Paddling a free Little Wolf for the first time in nearly 150 years

On June 28, 2026, we joined supporters of the Friends of the Little Wolf River for a paddle near Manawa, WI. 

On the July 4 weekend of 2024, Manawa received so much rain that the abutment of the dam on the Little Wolf gave away, effectively destroying a structure that had been in place for nearly 150 years. Since then, the greater Manawa community has debated the future of the dam, the mill pond the dam created, and the Little Wolf River itself.

Manawa dam in the Little Wolf River

Out of that community conversation formed a new friendship between Ben Hlaban and Nick Heise. They are calling for the Little Wolf to remain a free-flowing river. Both have deep family ties to the area and grew up fishing in the Little Wolf. They believe a free-flowing river is key to a more natural path to flood resilience in a changing climate where the next 100- or 500-year flood is no longer a matter of “if” but “when.”

The best way to learn about the beauty and benefits of a free-flowing river is to experience it first hand. So we loaded up our kayaks and helped a couple dozen fellow river enthusiasts join us on a guided trip. 

A changing river

In between waving to neighbors, pointing out bird species, and picking up trash, Ben and Nick explained how much the riverbed has changed since the 2024 flood. What used to be a mill pond is now a flowing river with clear water, native mussels, cold water tributaries, and migratory sturgeon. 

They pointed out good fishing spots, a train bridge that could be a future segment of the Tomorrow River trail, and how rain and the river have pushed sand and sediment into new places.

“The first thing I noticed was how quiet it was,” said River Alliance of Wisconsin Communications Director Stacy Harbaugh. “You just hear birds and the breeze. I also expected the gap between the former shoreline of the mill pond and the edge of the river to be more dramatic. What we saw was a river, a floodplain, and a lot of potential for restoration of this paddler’s delight.”

We stopped for lunch (catered by the friendly local diner, Sunrise Cafe) and a discussion at a local park where we heard from Ben and Nick about the options for the community. Undeterred by a little rain, we continued on to paddle past the former dam and into a more heavily wooded area that will be stunning in the fall. We wrapped up our trip with a visit to Linda Mae’s, a local ice cream parlor, for treats. 

The future of the Little Wolf

The community of Manawa, WI is still debating what to do about the dam. The City of Manawa’s consultants say that the dam cannot be fixed. Rebuilding the dam would cost $8 million. Removing the remnants of the structure and letting the river flow freely would cost around $700,000.

What isn’t included in that estimate is how a healthy river and floodplain can help protect the community from flood damage in the future. There are still a lot of misconceptions about the role of dams in flood control. 

The best place to learn about opportunities for public comments on the future of the Little Wolf River is by following the Friends of the Little Wolf on Facebook.

Read an opinion piece in Silent Sports magazine that is a deep-dive into the history of the Manawa mill pond, why dams are contentious, and why a free-flowing river has value by Timothy Bauer of Miles paddled.  

Timothy also documented the stretch of river we traveled back in October 2025 for Miles Paddled where you’ll find descriptions of where to put in and take out, the boulder gardens, and the little riffles that make the trip exciting. The included YouTube video gives you a good idea of what the river looked like in that snapshot of time.

By Vivian La, IPR

This story is made possible through a partnership between Interlochen Public Radio and Grist, a nonprofit environmental media organization.

Researchers from the University of Notre Dame have developed the most comprehensive look yet at how PFAS moves through the food web in the Great Lakes.

The study published this spring in the Journal of Environmental Quality analyzed 42 years of studies and combined nearly 2,500 samples of algae, fish, birds and other organisms — in what’s called a meta-analysis — to identify trends.

PFAS refers to a group of man-made and long-lasting compounds linked to a range of human health issues. It can enter waterways through landfills, wastewater and industrial facilities.

“What we’re finding is that the food web itself is a vehicle for transferring these chemicals from one organism to another,” said Gary Lamberti, aquatic science professor at Notre Dame and a study co-author. “So it’s a more holistic view than we’ve known before.”

The study identified a dramatic decrease over the last two decades of one PFAS chemical known as PFOS, following a voluntary phase out by industries in the early 2000s.

“If we stop manufacturing these chemicals, they will eventually reduce in concentration in the food web,” Lamberti said. “That’s kind of good news for how we can manage these chemicals.”

Those declines were seen in the lower Great Lakes — Ontario and Erie — likely because these areas are home to the heavy industries that used the chemical.

But there was little to no decline in PFOS in the upper Lakes Superior, Michigan and Huron, most likely because the water bodies are larger that the lower lakes. In contrast to the shallower Lakes Erie and Ontario, water can stay in the upper lakes anywhere from about 60 to 170 years.

The study also confirmed that these chemicals increase in concentration as they travel up the food chain. Algae and plants have the lowest concentration, according to the study, because they grow and die quickly.

But predators like salmon and eagles had the highest concentration because they’re eating a large amount of prey that have a lot of accumulated PFAS.

Potentially dangerous levels of these chemicals in fish have prompted warnings across the state on how much is safe to eat. Michigan has been testing fish for PFAS since 2012.

“If we can understand what the PFAS levels are in the food web, we can better communicate the risk of consuming those potentially toxic food sources,” said Katherine Manz, an environmental health professor at the University of Michigan who was not involved in the study.

But because PFAS chemicals are in everyday products and they’re very hard to avoid, Manz said her best advice is to use less. Online databases can help consumers avoid certain chemicals.

Manz said the study also pointed out some interesting gaps in research on PFAS dynamics, like a lack of data on certain species.

It was easy to find PFAS data on salmon, trout, and some birds, Lamberti said. But information on the “less glamorous” smaller fish, invertebrates or algae was harder.

The study only focused on six of the PFAS chemicals most commonly tested for, but there are more than 15,000 types out there, according to the National Institutes of Health.

Tools to analyze the range of these chemicals are still evolving, said Vernon Lalone, CEO of Traverse City-based startup Wave Lumina that’s developing a rapid testing kit for PFAS in water and soil.

“It’s like a chicken and an egg situation,” said Lalone, who wasn’t involved in the study. “You’ve got to have an analytical method that’s robust and reliable enough to measure these things before you can regulate them at certain limits.”

Lamberti said there’s still plenty of questions about how these chemicals will shift in the lakes as temperatures rise due to climate change, ice formation shifts and as industries introduce new chemicals.

“Anything we put into the Great Lakes will be there for an extremely long time, not only the water, but all the chemicals that it has, so we have to be very cognizant of how we treat the lakes and what we put into them,” Lamberti said.

In: forever chemicals, great lakes news collaborative, Latest News, North Bay, Ontario, PFAS, The narwhal, Water quality

By Leah Borts-Kuperman, The Narwhal

The Great Lakes News Collaborative includes Bridge Michigan, Circle of Blue, Great Lakes Now at Detroit PBS, Michigan Public and The Narwhal who work together to bring audiences news and information about the impact of climate change, pollution, and aging infrastructure on the Great Lakes and drinking water. This independent journalism is supported by the Charles Stewart Mott Foundation. Find all the work HERE.

Gathered in an arena in North Bay, Ont., in summer 2024, federal officials told hundreds of concerned citizens how they planned to remediate longstanding contamination of the city’s waterways left behind by the Department of National Defence. A few months later, officials gave a similar presentation to a packed hotel conference room.

For nearly a decade now, residents have known about the contamination. Some have been told not to drink the water from their own wells, and everyone in the city has been warned not to drink water or eat fish from a creek outside town.

The creek is part of a system of waterways where carcinogenic “forever chemicals” run downstream from a military base, emptying into Trout Lake, the source of the city’s drinking water. It sits at nearly double Health Canada’s guideline for PFAS in drinking water, measured in nanograms per litre. 

Health Canada published an “objective” level of 30 nanograms per litre in August 2024 for 25 chemicals in the PFAS family. That’s less than half of what Ontario currently recommends: 70 nanograms per litre, pertaining to just 11 PFAS chemicals. And that’s just a suggestion, not a binding regulation. 

The city did not reply to The Narwhal’s detailed questions regarding the current state of the drinking water supply, but CBC reported in February 2026 that Trout Lake contained around 58 nanograms of PFAS per litre of water.  

Thousands of substances classified as per- and polyfluoroalkyl substances, known as PFAS, are used to make everything from medical equipment to waterproof clothing. They can generate hazardous waste which, if not disposed of carefully, contaminates air, water and soil — where it can remain for 1,000 years, hence their other nickname, “forever chemicals.”

Statistics Canada reports almost all Canadians already have PFAS in their bodies, including in remote regions such as the Arctic and subarctic. 

In North Bay, the issue is top of mind, with a class-action lawsuit, a lengthy and expensive remediation plan and a new factory importing chemicals from the Teflon-like subgroup of PFAS, called PTFE. And the company behind that factory, Industrial Plastics Canada, is one of the 10 major importers of PTFE in Canada.

While PFAS have been making global headlines for years as an emerging threat to the environment and our bodies, North Bay knows the issue intimately; citizens fear for their water as politicians try to clean up the mess.

Here’s everything you need to know about PFAS in North Bay.

1. North Bay’s PFAS contamination comes from firefighting foam 

From the early 1970s to the mid-1990s, the Department of National Defence used a fire suppression foam containing PFAS to train firefighters across Canada, including near the North Bay Jack Garland Airport. In 2016, after the North Bay Parry Sound District Health Unit learned PFAS had been identified by the Department of National Defence in waterways around the city, it commissioned consulting firm Stantec to assess the impacts on soil and groundwater.

It’s the invisible nature of these chemicals that are part of what makes them so insidious; you can’t see them or smell them, so you don’t know they’re there without testing. 

“When you look at a mine, for example, you can see it and say, ‘That’s obviously disruptive to our ecosystem.’” North Bay-based environmental anthropologist Carly Dokis previously told The Narwhal. “But these things are invisible pollutants, which then tend to attract less public awareness.”

Stantec found PFAS from the foam had contaminated soil, bedrock, groundwater, private wells and several waterways in the region including Trout Lake, Lake Nipissing and Lees, Dorlan, Chippewa and La Vase creeks and surrounding areas.

In 2025, reporting by the Investigative Journalism Bureau surfaced a report by the Royal Military College showing the Department of National Defence found elevated PFAS levels around the base as far back as 2012. That means the department knew about the contamination for five years before revealing it to the City of North Bay in 2016, and the public in 2017.

2.  PFAS impacts health, environment and property values. Residents are seeking recompense

In late 2025, North Bay citizens filed a proposed class-action lawsuit asking for remediation, safe drinking water and $105 million in damages for residents living within a three-kilometre radius of the 22 Wing Canadian Forces Base and Jack Garland Airport. Some of the people who live closest to the contamination have been receiving bottled water from the government for years, but have had no other opportunity for recourse.

The proposed lawsuit, if certified by the court, would be against the City of North Bay and the Attorney General of Canada, on behalf of the Department of National Defence, focusing on the loss of property value and remediation costs. The case is also seeking punitive damages, contending that National Defence was aware of the contamination long before warning residents.

Not mentioned in the suit is the long list of health concerns associated with “forever chemicals.”

The United States Environmental Protection Agency lists potential health risks of exposure to PFAS, including reproductive problems like infertility, developmental effects in children, increased risk of certain cancers and weakening of the body’s immune system, including reduced vaccine response. The Canadian government says PFAS can be transferred through the placenta during pregnancy, and infants can be exposed through human milk. 

Ecosystems are affected, too. Studies have shown exposure to per- and polyfluoroalkyl substances can stunt plant growth and cause reduced seed germination and ability to photosynthesize. The chemicals can build up in the organs of living creatures throughout the food chain. In the district of Nipissing, that poses a risk to people who hunt, fish and harvest from the land.

“These industrial areas are often surrounded by lower-income buildings and peoples and communities,” Curtis Avery, environment department manager with Nipissing First Nation, told The Narwhal in summer 2023. “We’re the most vulnerable group of people that utilize our lands — the lands are our grocery stores. … If these are being impacted, we need to know.”

3. Cost of North Bay clean-up grew five-fold, to more than $100 million

In 2021, the City of North Bay announced plans to begin remediation under a “shared responsibility” agreement between the Department of National Defence and the city. The federal department would cover 97 per cent of the costs, or $19.4 million, and the city would cover the remaining three per cent, at $600,000. But costs have ballooned since then; in December 2025, National Defence announced it would contribute another nearly $100 million to the remediation, with the city’s share rising to more than $3.6 million. The total for the cleanup project has risen to more than $122 million.

The remediation, which began on the ground in 2024, includes excavating and disposing of about 26,000 tonnes of PFAS-impacted soil; injecting activated carbon material into particularly dense patches of PFAS to stop the underground plume from spreading; and installing a filtration system to treat water leaving the site.

“We remain committed to addressing and managing the operational legacy of the Canadian Armed Forces responsibly,” Minister of National Defence David J. McGuinty said in a news release.

As part of the process, a notice went up on the federal Impact Assessment Agency registry on April 28, inviting the public to comment up until June 5 on a proposal to install a 250-metre permeable barrier in the ground to help filter impacted groundwater. A spokesperson for the agency said its role in the project is to offer advice on determining its environmental effects, as well as providing the opportunity to post the project on the registry.

Local organizations, including the environmental group Northwatch, said in a press release that they were concerned about “very limited public engagement over the last ten years since the public disclosure of the contamination,” counting only the two forums in 2024 and 2025, where there was “limited opportunities for the public to ask questions.” 

Northwatch’s project coordinator Brennain Lloyd told The Narwhal about the public notice period, which she said her organization only learned of in a daily bulletin from the Impact Assessment Agency listing multiple assessment notices from across the country.

“To the best of our knowledge there were no local announcements or invitations to comment issued to the many residents and organizations who have identified their interest in this program,” a release from Northwatch reads.

The Department of National Defence did not respond to questions from The Narwhal. 

4. North Bay’s not alone: contaminated military bases affect communities across Canada

Contamination on federal sites is an issue across Canada. There are thousands of contaminated sites listed on the federal contaminated sites inventory, and PFAS are found on more than 100 of them. These include at least 26 National Defence sites including bases in Trenton, Ont., Gagetown, N.B., and Moose Jaw, Sask.

And contaminants don’t stop at the fenceline. Health Canada says some contaminants can travel long distances through soil, water and air: “PFAS can be found in fresh water and drinking water in areas that are far away from where they entered the environment,” according to the department’s website.

5. Industry is still importing PFAS-class chemicals into North Bay

While the Canadian government no longer uses firefighting foam that contains PFAS, industry continues to bring these substances into the country. In 2023, The Narwhal reported on an international plastics conglomerate that opened its first Canadian location, Industrial Plastics Canada, in North Bay. The company has a presence across Europe as well as in India and China, billing itself as one of the “largest worldwide manufacturers of PTFE products.”

PTFE, or polytetrafluoroethylene, is a Teflon-like product in a subgroup of PFAS known as fluoropolymers, or fluoroplastics. A company spokesperson previously told The Narwhal the use of PTFE at the factory will not produce waste and poses “no risk.” The company also says fluoropolymers aren’t as dangerous as other PFAS and are “considered safe, non-bioaccumulative and non-toxic.” 

But fluoropolymers have been found to be dangerous to human health, according to research published in the peer-reviewed journal Environmental Science & Technology and others.

In 2023, Health Canada released a draft assessment of the state of PFAS in Canada to help decide how to regulate the class of chemicals. In it, the agency cited an industry-funded study that said fluoropolymers should be considered separately from other PFAS as “polymers of low concern.” A Health Canada spokesperson said the agency, along with Environment and Climate Change Canada, “examined information from a wide range of sources,” including scientific journals and reports while preparing the state of PFAS report.

The substances were ultimately excluded from the final report, released in March 2025, in which Health Canada proposed classifying the remaining PFAS chemicals as toxic substances under the Canadian Environmental Protection Act.

The Health Canada spokesperson said in an email that fluoropolymers “have specific properties that differentiates them from other PFAS,” which led to their exclusion from the final report. They added that the exclusion “should not be interpreted as meaning they are or are not of concern,” and that a separate fluoropolymer assessment is currently underway.

The exclusion of PTFE from that classification was a major priority for industry, Rémy Alexandre, toxics project lead at environmental law non-profit EcoJustice, told The Narwhal.

According to data collected by Alexandre, who studied Industrial Plastics Canada’s imports to North Bay, the company brought in almost 207,000 kilograms of PTFE from India and China from July 2025 to May 2026.

This puts the facility on the list of the 10 major importers of PTFE in Canada, alongside U.S.-based chemicals company Chemours, a spinoff of Dupont that has been arguing that the European Union should exempt fluoropolymers from their regulations, too. 

“The decision to site this plant in a community that is an existing hotspot for PFAS raises concerns,” Alexandre told The Narwhal. “And so does the selection of a jurisdiction that isn’t regulating fluoropolymers.”

Manawa: Paddle the Little Wolf River with us on June 28

River Alliance of Wisconsin welcomes paddlers to join us on the Little Wolf River near Manawa, WI for a recreational opportunity to experience a free-flowing Little Wolf after the destruction of a dam after a storm and flood in 2024.

Register for the June 28 Little Wolf paddle

Join us on the Little Wolf River

On Sunday, June 28, we will meet up at 10 a.m. at a riverside location north of Manawa, Wisconsin. Location details will be sent to event registrants by email. Bring your own boat, and we will assist with a vehicle shuttle. A boxed lunch will be provided. Weather updates or an event cancellation will be shared with registrants the morning of the event by email. There is no rain date for this paddle.

Why paddle the Little Wolf

Paddling a free-flowing Little Wolf River is a significant action. There has been a millpond in Manawa since the 1870s when settlers dammed the river for the logging industry, and the dam was rebuilt in 1920s as a small hydropower dam. The segment of the river hasn’t flowed freely in 150 years.

On July 5 2024, heavy rains impacted the land around the Manawa Dam. The banks eroded, the flooded millpond destroyed part of the dam, and areas of the city including the annual Mid-Western Rodeo had to be evacuated. Since then, the Manawa community and their neighbors have debated whether to repair, rebuild, or remove the Manawa Dam, which had structural deficiencies even prior to the flood.

A feasibility study by the Cedar Corporation emphasized that repair was not feasible, replacement would cost $8.4 million, and removing the remnants of the dam and restoring the shoreline could cost as little as $700,000. From a cost perspective, the solution is clear. But what is harder to measure is the ecological and recreational value of the Little Wolf River.

That’s why we hope you’ll join us to see how the river has returned to a free-flowing state. We can witness the return of plants on its banks, scout for native mussels, and talk about what a river could do for the community’s future flood resilience in a changing climate. Bonus: we’ll get ice cream at the end of the trip!

In: Michigan, PFAS, Water Quality and Restoration Efforts

By Sarah Cwiek, Michigan Public

The Great Lakes News Collaborative includes Bridge Michigan; Circle of Blue; Great Lakes Now at Detroit PBS; Michigan Public, Michigan’s NPR News Leader; and The Narwhal who work together to bring audiences news and information about the impact of climate change, pollution, and aging infrastructure on the Great Lakes and drinking water. This independent journalism is supported by the Charles Stewart Mott Foundation. Find all the work HERE.

Compounds from the family of chemicals known as PFAS can suppress the body’s ability to mount a defense against new pathogens — and the effects can last well into adulthood.

That’s one conclusion from a new Michigan State University study that looked at how people in two West Michigan communities that had PFAS-contaminated water responded to the virus that causes COVID-19.

Courtney Carignan, an environmental epidemiologist and the lead researcher for the MSU team, had already been conducting PFAS impact studies in Parchment and Cooper Township near Kalamazoo. Both communities were home to paper mills, and in 2018, state testing found that public water supplies had been historically contaminated.

Carignan said it’s well-established that PFAS chemicals are immunotoxic in children, but it’s been harder to study that impact on adults. That’s because adult immune systems have already been exposed to a number of pathogens that trained their immune systems to respond by producing antibodies, the frontline “soldiers” of immune response.

So when the COVID pandemic struck, Carignan and her team took the opportunity to look at the immune responses in adults participating in the existing research. And what they found was striking: a strong link between blood levels of a certain PFAS compound — perfluorohexanesulfonic acid, or PFHxS — and fewer defensive antibodies being produced in response to COVID exposure through vaccination.

“And so we infer then that people who have higher exposures, if they’re producing less antibodies, then their bodies are less able to fight an infection,” Carignan said.

“It reinforces what we know about these contaminants — that they have been phased out of use because they’re known to be harmful, that they are immunotoxic, and that these effects persist into adulthood.”

Carignan added that while some classes of PFAS have been phased out, including PFHxS, thousands more remain in use.

They’re known as “forever chemicals” because of how long they take to break down in the environment and in human bodies. In addition to immunotoxic properties, they’re also known endocrine disruptors and linked to multiple types of cancer.

PFAS are so prevalent in the environment that nearly everyone has some level of them present in their body. However, Carignan said there doesn’t appear to be a link to suppressed immune response correlated with those lower levels.

“Most of us, unfortunately, do have these chemicals in our body,” she said. “[But] at those levels, we don’t really see not producing enough antibodies to be protected.”

The study comes at a time when the U.S. is still debating PFAS standards for drinking water. The U.S. Environmental Protection Agency finalized its first enforceable drinking water standards for certain PFAS chemicals in 2024, but implementation timelines and enforcement for some compounds have since been pushed back, according to Carignan. Michigan, however, has its own standards.

“I think Michiganders can know that our state is doing more than other states, and we have more protections,” Carignan said. “That’s a good thing.”

Data Center bills in the Wisconsin State Legislature

On February 17, 2026 the Wisconsin Senate Committee on Utilities, Technology, and Tourism held a hearing on data center development bills. River Alliance’s Agriculture and Policy Director Mike Tiboris attended the hearing and submitted the following testimony on why our state should pause new data center construction until our leaders fully understand the implications of how industries with extreme energy and water demands will have on our resources.

Chair Bradley and the members of the Committee on Utilities, Technology, and Tourism:

Thank you for holding this hearing for several bills on the emerging issues related to data center development in Wisconsin. River Alliance of Wisconsin has registered neutral on SB 729 and opposed on both SB 843 and AB 840 as written. River Alliance is a statewide nonprofit, nonpartisan advocacy organization that empowers people to protect and restore Wisconsin’s waters at a local level. The organization’s supporters include more than 5,000 individuals and businesses and nearly a hundred local watershed organizations. 

All of these bills recognize that we must thoughtfully confront the sudden construction pressure from a rapidly evolving technology. Our concern is that we do not allow Wisconsin’s water, among our most valuable public assets, to be mortgaged for unproven benefits and without adequate protection. A medium-sized data center consumes as much water as 1000 households per year for cooling (110 million gallons). Rapid and improperly regulated data center construction poses a potentially serious threat to our natural water resources. The benefits to Wisconsin of data center construction are unproven, but the hazards to our water are quite clear. Data centers directly use water to cool servers that generate heat either through evaporative cooling or through the addition of contaminants that can be discharged in wastewater and enter the environment. Further, these facilities may invite the construction of new hydropower facilities on already taxed river systems and cause aging, outdated, facilities to stay online. Often touted as “green”, hydropower operations can cause myriad negative environmental impacts, from preventing fish migrations to reducing water quality and water quantity at critical times of the year, affecting aquatic life and recreation.

Our preference in this moment of uncertainty would be to pause all new data center construction until we can develop appropriate legislative mechanisms for managing its downsides. Legislators’ recently proposed moratorium on data center construction should be used to give the Legislature time to create thoughtful controls that ensure new data centers actually benefit Wisconsinites and do not cause problems we could avoid if we took the time to prepare for them. Our abundant natural water and land resources are an obvious attraction for companies that want to build projects in Wisconsin, but we should be very careful to make sure the benefits are not simply handed to companies to export from the state for their own profit at the cost of damage to an irreplaceable public good and, at best, uncertain employment or tax benefits.

 

SB 729

River Alliance has registered neutral on SB 729. We are supportive of the bill’s emphasis on making sure that data centers pay for the energy that they use and that their usage does not drive up the cost of energy for Wisconsin homeowners. Similarly, it is common sense that such large water users should be required to report on their usage when it accounts for 25 percent or more of the total water usage of all customers for a water utility. Enforcing transparency about usage will help communities, utilities, and municipalities respond appropriately to water demand increases that could have very negative effects on local water sources, ecosystem health, and the costs of water provision.

We support the idea of encouraging data centers to rely on renewable wind and solar energy sources. SB 729 would require that at least 70 percent of the total annual electric energy used by the buildings be derived from renewable resources, as defined under s.16.75(12)(a)4. The definition of “renewable energy” referenced, however, includes hydropower, and we do not support the construction of new hydroelectric generation facilities to power data centers. 

Many people believe that hydropower, which uses dams and gravity to spin electricity generating turbines, is a clean, climate-smart, energy source. This is a misconception. While wind and solar power offer renewable low-carbon energy and are generally cheaper than fossil fuels, hydropower can cause environmental damage. Dams and reservoirs alter river flows, raise water temperature, degrade water quality, increase sedimentation in reservoirs, and prevent migrations of fish and native mussels harming aquatic ecosystems and Wisconsin communities. Reservoirs are a significant source of greenhouse gas emissions, predominantly methane, an especially potent greenhouse gas, that results from eutrophication and harmful algal blooms.

Again, River Alliance supports the approach that SB 729 takes to create water usage transparency and accountability, to ensure that the costs of new energy and water demand are borne by the data centers and not by other customers, and to encourage the use of renewable energy like wind and solar as power sources. We are concerned that, in its current form, the bill will encourage expansions of hydropower generation that will extensively damage aquatic ecosystems and may be more destructive to the climate than fossil fuel use in some cases.

 

SB 843 and AB 840

The above reasons also underwrite our opposition to both of these bills as written. The bills require that “any renewable energy facility that primarily serves the load of a data center must be located at the site of the data center.” (Section 2. 196.492(2), lines 16-17). Again, using the definition of renewable energy from s. 196.378 (1)(fg), we are concerned this will encourage the construction of new, environmentally damaging, hydropower facilities. Limiting the use of renewable energy to sources constructed on site is unnecessarily restrictive and would likely have the effect of discouraging renewable energy use entirely. Because the bills do not explicitly require that data center owners pay the full cost of their energy use, this will drive up the cost of energy for Wisconsin residents while increasing pollution.

However, the requirements to require reporting to the DNR about annual water usage and to ensure that the costs of reclamation and failure of the facility are borne by the data center owners are sensible. 

We are encouraged by the serious interest the Legislature is taking in managing the environmental consequences of data center construction. Given the likelihood that the industry will expand rapidly in the coming years, we hope this is the beginning of a sustained conversation about how to ensure that the benefits of data centers accrue to Wisconsinites and that these do not come with irreparable harm to our land and water resources.

Watch “How do PFAS affect Wisconsin’s fish?” (Video by Bonnie Willison / ASC)

In order to become big fish, baby fish face seemingly impossible odds. They evade predators, find food, and fend off disease — all while being smaller than the size of a fingernail. But what if contaminants in the water affect their ability to respond to those challenges and survive?

With funding from Wisconsin Sea Grant, University of Wisconsin–La Crosse Professor Tisha King-Heiden is studying how per- and polyfluoroalkyl substances, or PFAS, impact the nervous and immune systems of young fish. PFAS are a family of chemicals found in non-stick and waterproof household products, from food packaging to dental floss. They’re widespread in lakes and rivers across Wisconsin. 

“What I’m interested in is how exposure to environmental contaminants during early stages of embryonic development can lead to adverse health effects later on in life,” said King-Heiden. 

Her work on the project is personal. King-Heiden lives on French Island in Campbell, Wisconsin, where the groundwater is contaminated with PFAS. 

“It hit home pretty hard. I’ve been on bottled water now for going on five years,” she said. “So I just wanted to try to contribute a little bit more to understanding what the risks are and what they aren’t, because there’s still quite a few unknowns.”

New PFAS, new fish

With over 7,000 types of PFAS, King-Heiden is zeroing in on three newer chemicals: PFHxS, PFUNdA, and PFNA. Not much is known about how they affect fish, as past studies have primarily focused on older, “legacy” PFAS that are no longer used but remain in the environment. 

 ”The vast majority of information we have is on PFOA and PFOS. So those are […] the original PFAS chemicals,” she said.

PFHxS, PFUNdA, and PFNA have slightly different chemical structures than the legacy PFAS, which may affect how they accumulate in and affect fish. 

Another novel aspect of King-Heiden’s project is the type of fish she’s studying: fathead minnow, walleye, and sturgeon. Many PFAS studies use zebrafish, a popular lab species from southern Asia.

“I wanted to try something different and start working with some other prevalent species that are more ecologically and culturally relevant to people living in Wisconsin,” she said.

Measuring tail flicks and body bends

To evaluate the effects of PFAS on fish, King-Heiden and her team are collecting data on hatching success, growth, and immune system responses. They’ve also developed a series of behavioral tests to gauge how the nervous system develops.

The first test? Watching fish embryos for tail flicks.

“It’s the same thing that humans feel when they can start to feel the fetus moving,” said King-Heiden. “If they are flicking their tails too much, or if they’re not flicking them enough, it can give us an idea of how PFAS is impacting that nervous system development.”

After the fish hatch, the team then measures how well they can respond to stimuli. King-Heiden explained that during this time, fish develop neurons along their body that help them sense movement in the water. And when they do detect movement — a lurking predator, perhaps — the fish bends into the shape of “C” and swims away. It’s called a C-start response.

“It’s an autonomic reflex, like the knee-jerk reflex,” she said. 

Using a high-speed camera, the team measures how long it takes for a fish to respond to a vibration sent through the water. The longer the response time, the more likely the neurons are damaged. 

The final behavioral test raises the stakes. Instead of contending with vibrations, a baby fish is placed in a container with a hungry adult fish.

“We give them a certain amount of time and see if the fish can actually escape that predator,” King-Heiden said. Cumulatively, the tests can indicate how the nervous system is developing and how baby fish might survive in the wild.

Protecting wild fish and people

While PFAS concentrations in lakes and rivers may not be high enough to kill baby fish, they could make them more susceptible to predation and disease. King-Heiden said that could spell trouble for wild fish populations, especially if they’re dealing with other issues, like invasive species. 

“If you add other environmental contaminants and stressors like disease to that mix, you can exacerbate the problem,” she said. 

Human health is also a concern, as people catch and eat fish from contaminated water. Understanding if and how the new PFAS accumulate in tissues of fish can help set consumption advisories that keep people safe. King-Heiden is also developing a communication campaign to engage local communities around PFAS, fish, and human health.

“We can try to help explain why it’s important for us to spend the money to clean up PFAS, to spend the money to support the research that’s going to find the most cost-effective way of cleaning up our drinking water for both human health as well as our wildlife,” she said.

PFAS compromise bills must limit spills law exemptions

UPDATE – March 17: River Alliance of Wisconsin applauds the Wisconsin State Senate for unanimously approving PFAS bills AB 130 and AB131 to send the bills to Governor Evers to sign. On February 20, the Wisconsin State Assembly voted unanimously on bills that would release the long-awaited PFAS trust fund money to help fund PFAS remediation projects.

Clean water advocates voiced clear concerns during the years-long debate over spending the state budget funds and how to define innocent landowners. Ultimately legislators wrote a compromise that will make some needed progress in creating remediation grants and some limited exemptions to the state’s Spills Law.

It is because of people living with PFAS pollution who have tirelessly steered legislators into action to meaningfully release funds for drinking water remediation in Wisconsin. We encourage Governor Evers to sign this legislation and state legislators to continue to work to ban the use of PFAS-style chemicals.

 

 

On January 21, 2026, state legislators held another hearing on policies and funding for addressing PFAS contamination. The bills are the result of many months of debate and compromise. Through the whole process, we’ve listened to leaders of impacted communities and experts across the state and held firm on three core issues.

We insisted that since the 2023 state budget was passed, the Joint Finance Committee has always had the power to release the over $125 million of funds earmarked for action on PFAS. Though JFC leaders refused to release the money to communities with contaminated water, this legislation would finally move dollars out the door.

We insisted that our state should not make Swiss cheese out of our Spills Law with broad and vague exemptions for corporate pollution accountability. While we would prefer fewer exemptions to the Spills Law, we understand the need to exempt truly passive receivers, like farmers.

Finally, we insisted that there was no community left behind when it comes to accessing the funds needed to test, filter and remediate drinking water resources. We cannot support a bill that would create new policies and grant programs without hiring state experts to administer grants and enforce laws. The only way we would support this legislation is with an amendment to hire adequate DNR staff.

With the legislative session winding down and elections coming this fall, legislators are under pressure to have some progress to report to their constituents. Governor Evers has signaled his optimistic support for this compromise. However, from the start, this bill was an effort to exempt big businesses under the guise of helping innocent landowners. Adding further exemptions to protect already identified polluters is unacceptable.

It is only due to the many hours – years, in fact – of vocal members of impacted communities and clean water advocates that got PFAS contamination to be a household word and to push state leaders to do the right thing for our water.

We’re only at the beginning of providing remedies for communities living with water pollution. The people of Wisconsin cannot wait for funds from lawsuit settlements over PFAS pollution to get help for their drinking water. The state legislature must release the funds, hire the staff, and set their sights on the next step which is to ban PFAS-style chemicals and prevent further damage to our water.

Contacting your legislators will make an impact. 

Please contact your State Representative to let them know the people of Wisconsin have waited for action on PFAS for far too long and they should support Assembly Substitute Amendment 1 to AB 131, and Assembly Substitute Amendment 1 to AB 130 without further exemptions.

By Kelly House, Bridge Michigan

The Great Lakes News Collaborative includes Bridge Michigan; Circle of Blue; Great Lakes Now at Detroit PBS; Michigan Public, Michigan’s NPR News Leader; and The Narwhal who work together to bring audiences news and information about the impact of climate change, pollution, and aging infrastructure on the Great Lakes and drinking water. This independent journalism is supported by the Charles Stewart Mott Foundation. Find all the work HERE.

In the years since Michigan’s PFAS crisis became public knowledge, widespread contamination has prompted a growing list of “do not eat” advisories in waterways across the state.

But a study published this month in the Journal of Great Lakes Research offers hope that, one day, the fish could be safe to eat again.

The study was conducted by researchers in the former US Environmental Protection Agency Office of Research and Development, which the Trump administration has since dismantled amid a broad push to curtail federal oversight and loosen regulations on a host of chemicals, including PFAS.

Using decades’ worth of archived lake trout and walleye samples originally collected to track older pollutants like mercury and PCBs, scientists discovered PFAS levels in Great Lakes fish have declined significantly since the late 2000s, when manufacturers began phasing out once-common compounds like PFOS and PFOA amid growing regulatory pressure.

“The ecosystem responded very quickly to these changes in industrial production,” said Sarah Balgooyen, a lead author of the study and former EPA chemist who is now a researcher at the Colorado School of Mines.

A growing body of research has linked certain PFAS (an acronym for a class of thousands of chemicals known as per- and polyfluoroalkyl substances) to cancer, thyroid problems and developmental, fertility and immunity challenges.

The research team tested for 45 compounds, using fish taken from the Great Lakes between 1975 and 2020. They found that average contamination levels by 2020 had reached their lowest since the 1980s.

In Lake Erie, for example, PFAS levels in the freeze-dried tissue samples peaked at close to 450 nanograms per gram in 2005 but were closer to 50 nanograms per gram in 2020. In Lake Michigan, levels reached a high of about 150 nanograms per gram in 2010 before drifting down to about 80 nanograms per gram in 2020.

“We hope to see that trend continue,” Balgooyen said.

That’s welcome news to Chris Matteson, a 76-year-old from Muskegon who has been fishing in the Great Lakes since the days when factories lined the shore, spewing effluent so foul that, “if you could see a foot into the water, that was pretty good.”

“I’ve been through a lot of fish warnings,” Matteson said.

Although PFAS manufacturers have known their products are toxic since at least the 1970s, the public wouldn’t learn until decades later. Unregulated use of the so-called “forever chemicals” allowed them to escape into the environment, poisoning drinking water and embedding in the bodies of humans, fish and wildlife.

Only in recent years — after a series of contamination scandals — have state and federal governments begun regulating PFAS and investigating the extent of the pollution.

In 98 Michigan water bodies, some fish species are so full of PFAS that state health officials say it’s not safe to eat them. Health advisories in hundreds more water bodies call for limiting meals to anywhere from 16 servings a month to six a year.

Michigan Department of Health and Human Services spokesperson Lynn Sutfin said agency staff are reviewing the study.

For now, she said, “our advice for anglers remains the same: To learn how to choose safer fish to eat, follow the Eat Safe Fish Guides.”

Find out whether your local fishing spot is affected here.

Gary Ankley, a former EPA research toxicologist and coauthor on the study, said the declining PFAS levels are encouraging. But there is no way to know how low PFAS levels will ultimately fall.

Known as “forever chemicals” because they don’t break down readily in the environment, some amount of PFAS will remain in the lake indefinitely, Ankley predicted.

Balgooyen cautioned that the study offers only a partial picture of PFAS risks in the lakes.

While manufacturers have largely stopped using the so-called “long-chain” PFAS compounds that tend to bioaccumulate in fish, many have switched to new “short-chain” compounds that do not.

The health risks of those newer compounds have not been well-studied.

“We’re seeing decreases in these compounds that we know are harmful, which is great,” Balgooyen said. “But there’s still this unknown component of the replacement chemicals.”

Citing evidence that PFAS is more toxic than previously thought, state and federal regulators in recent years have lowered allowable PFAS levels in drinking water and taken other steps to discourage the chemicals’ use.

Seeking to make the EPA more business-friendly, the Trump administration has reversed some of those actions, announcing plans to loosen PFAS drinking water standards and requirements for manufacturers to report their PFAS use.

EPA Administrator Lee Zeldin called those “commonsense” changes that would lower costs for industries and water providers while still protecting the public.

But Matteson, the Muskegon fisherman, views the administration’s loosening of environmental regulations differently.

“The companies will go back to the easiest, cheapest way to do anything,” he said. “Most likely, it isn’t environmentally friendly.”

In: bald eagle nestlings, Brian Dhuey, Dan Goltz, Emily Cornelius Ruhs, Great Lakes Eagle Health Project, Lindsey Long, PFAS, Wisconsin River

It hadn’t been a successful morning for the Great Lakes Eagle Health team.

Traveling by boat, truck, and foot, the team was searching for active eagle nests along the Wisconsin River in Nekoosa, Wisconsin. Tree one was a dud, and tree two, a heartbreaker. Dan Goltz, one of the team’s climbers and a wildlife biologist with the Wisconsin Department of Natural Resources, scaled a 70-foot tree only to be met with a gentle breeze blowing through an empty nest.

“It’s always a nice view,” he sighed, coiling his rope for the next climb. 

The team, however, had reason to be optimistic about tree number three, located on the grounds of a paper products factory on the river.

For one, it was streaked with whitewash, or eagle poop. Loathe to defecate inside their nests, baby eagles poop off the sides, spraying the ground with what looks like white paint. Fresh whitewash usually indicates an active nest. 

The second promising sign was that the tree was a white pine — Goltz’s favorite. Unlike cottonwoods, whose deeply furrowed bark could chip off under the pressure of spurred boots, white pines are smooth and offer stability. Goltz’s footholds would be more secure, and his climb, safer. Snapping on a hot pink helmet, he spiked his shoes into the trunk and began to haul himself upward.

And then there was what was happening above Goltz’s head. A bald eagle, clear against the high-noon sky, flew into view and began to circle and chirp. A second soon joined to voice its displeasure at the man approaching the nest.

“That’s a great sign when you hear the bird chirping at you like that,” said Brian Dhuey, WDNR research technician, peering through the trees. “It means there’s something to protect.”

The presence of the eagles energized the team on the ground. Lindsey Long, a WDNR wildlife veterinarian, kneeled on a blue tarp and began to unpack her sampling equipment: tubes, syringes, glass slides, a small machine that repels mosquitoes. Two volunteers huddled closer and listened as she explained protocol for taking blood. Dhuey shuffled among the dry leaves.

Now, they waited. Necks craned toward the sky, the team watched Goltz climb, hoping for news of a bird.

What eagles can tell us

The Great Lakes Eagle Health Project has tracked contaminant levels in bald eagles across Wisconsin since 1990. Currently funded by the National Oceanic and Atmospheric Administration (NOAA) and U.S. Geological Survey, the project brings together federal, state, tribal, and academic partners to test eagles for a variety of pollutants, like heavy metals and PCBs, and investigate how they’re affecting eagle health.

In 2023, Wisconsin Sea Grant’s emerging contaminants specialist Gavin Dehnert joined the project to investigate a new problem: per- and polyfluoroalkyl substances, or PFAS. 

Dubbed “forever chemicals,” PFAS don’t break down easily and are found in common household products like non-stick pans and water-repellant clothing. They’re harmful to human health and have been found in high concentrations in drinking water in communities across Wisconsin, like French Island and Marinette.

Dehnert, who has studied PFAS in maple syrup, wild rice, and fish, said eagles are what’s known as a “sentinel species,” organisms that can alert humans to environmental toxins — like a canary in a coal mine. Due to their diet, bald eagles are particularly good indicators of how much PFAS are in the environment.

“They eat a lot of the same foods that we do,” said Dehnert, like fish and deer. “And because they also eat both aquatic and terrestrial food sources […], they give us a really good idea of how much contamination is in the area.”

The team exclusively takes blood samples from baby eagles, called nestlings, that are younger than 12 weeks old. Because they cannot fly, the nestlings’ main exposure to PFAS is from the food their parents bring. This means that their blood samples provide clues to how contaminants are moving through and accumulating in the food web.

Each year, the team chooses different sampling sites. In May of 2025, they focused on the Wisconsin River, spending two weeks sampling eagles from Prairie du Chien to Minocqua.

“Because the Wisconsin River is so long and vast, it gives us a really good gradient of how these PFAS levels are changing,” said Dehnert. The team expects levels to be higher in the middle section of the river due to the presence of industries that have historically used PFAS.

In addition to measuring PFAS levels, Dehnert and Emily Cornelius Ruhs, an ecoimmunologist and postdoctoral researcher at the Field Museum, are studying how the contaminants affect eagle health, specifically their physical bodies and immune function. Do PFAS weaken eagles’ ability to fight off illness? Do they impact hormone levels? How are eagles growing and developing?

“We don’t know a lot about it or how it impacts wildlife,” said Cornelius Ruhs.

But a lot of information can be gleaned from a blood sample.

Landing the bird

The news was good. Secured to the tree with ropes, Goltz had peered across the eagles’ platform of sticks and declared there was not one, but two nestlings in tree number three. The task now was to safely transport the birds through the canopy to the team below.

Long mused at the feat from her spot on the blue tarp.

“The climber has to get that in a bag by himself,” she said. “It’s pretty amazing, the skillset that they have. Both of our climbers are also really, really, good at bird handling and are really conscientious.”

The climbers use what’s essentially a chicken hook — a tripod leg with a hook on the end — to coax the eagles toward their bag. Goltz’s hook had green glitter on it, which, he deadpanned, mesmerized the birds.

A joke, perhaps, but sometimes the rally cap prevails. Goltz’s bag lowered into view, and Dhuey swiftly claimed it.

Bird in tow, Dhuey walked back over to the team. He weighed the bird, still in its drawstring pouch, and knelt next to Long. With blue surgical gloves on their hands, they peeled back the bag to reveal the fluffy bundle they’d been chasing all morning. Dhuey held the bird as Long made final preparations for the blood draw.

Chocolate brown with sulfurous yellow feet, the nestling was no less striking than its parents. Its talons were curved and black, and under Dhuey’s strategic grip, they looked positively reptilian. The eaglet looked around at the team, a breeze riffling its feathers.

Long was ready. She helped Dhuey lay the nestling on its back and covered its head to keep it calm. One hand holding the feet, one hand unfurling the wing, Dhuey secured the bird. Long grabbed the syringe. The choreography between them was familiar and swift, two researchers practiced in the art of data collection.

Long crouched over the wing. Earlier, she said taking blood from an eagle is like taking blood from a human. Cold temperatures and dehydration can make the draw harder.

“Sometimes we have to do a little manipulation,” said Long, “just like if you’re at the hospital and they’re like, can you pump? Or, you need to move your arm a certain way or make a shift.”

On this unusually warm day in early May, the eagle wasn’t cold or dehydrated. Dark red began to spiral through a thin tube into the syringe.

Keeping eagles in the sky

Once collected, the blood samples are smeared onto slides and prepared for further testing. That’s where ecoimmunologist Cornelius Ruhs comes in. Her job is to decode what the blood says about the nestlings’ health.

“The blood sample is used for many things. The first one is a white blood cell count,” she said. “And that’s pretty much the same as what you would get at a doctor’s office, like a CBC or blood panel.”

Cornelius Ruhs also measures total antibody levels in the bird’s blood, levels of two different thyroid hormones, and corticosterone, a stress hormone. Additionally, the team is running a new test that’s only been done on humans and other primates. Known as an “ex vivo blood challenge,” the test mimics bacterial and viral infections in a tube containing live blood from the bird. The blood can then be sent off and analyzed for how it responded to the challenges.

All these data points tell a story about how well a baby eagle can fight off infection, like bird flu. The hypothesis is that “being exposed to high levels of PFAS might cause [eagles] to not respond as well or mount a response to a viral or a bacterial challenge,” said Cornelius Ruhs.

And that’s a concern for an iconic bird that was, in the 1960s, nearly extinct. “Bald eagles have been hit so hard by contaminants in the past, like DDT,” said Cornelius Ruhs.

Prior to being banned in 1972, DDT was widely used to kill mosquitoes, but it also weakened the eggshells of birds like bald eagles that ate contaminated fish. The eggs cracked under the weight of the incubating birds, causing reproduction rates to fall.

Long-term studies like the Great Lakes Eagle Health Project, however, can sound the alarm before something like that happens again. Bald eagles are beloved birds, and many folks want to continue seeing them thrive.

“This project is really special, I think, to all of us, not just because we get along so well and we all enjoy working with each other, but just because of the uniqueness to it,” said Cornelius Ruhs. “I don’t think a lot of people get to work with these large, majestic animals.”

A good day’s work

In under 10 minutes, the team had taken blood and measured beak, wings, and feet. Dhuey then snapped a lightweight metal band to the eagle’s ankle, a way to track and identify the bird. The cuff glinted like new jewelry above the outsized yellow feet.

Long and Dhuey then gently folded the bag over the bird to be ferried back up the tree as quickly as it came down.

The experience at tree number three went unrivaled. After lunch — the team had gotten ice cream, they claimed, to ensure their good fortune — they found an unoccupied nest in a cranberry bog and ended the day with another eagle-less climb up a tall white pine near the river.

It was clear that camaraderie kept the team going, even during the busts. They work two weeks together every year, crammed in aluminum boats, fighting heat and mosquitoes, processing blood samples in hotel parking lots. Several team members said they spend the weeks following field season looking out of car windows, looking for nests. They can’t help it.

This spring, it’s the Mississippi River.

“Every day is just getting us back to eagle sampling field season,” said Cornelius Ruhs.

A new study recently published in the “Journal of Environmental Health” shows that large numbers of Americans are searching online for ways to reduce their exposure to PFAS, a group of synthetic “forever chemicals” found in everything from nonstick pans to takeout containers.

The research also showed that when people did search for PFAS — which is short for per- and polyfluoroalkyl substances — they focused specifically on how to filter the chemicals from their drinking water.

“People are clearly trying to take action,” said Bret Shaw, a professor in the Department of Life Sciences Communication and the Division of Extension at the University of Wisconsin–Madison and co-author of the study. “They’re looking for actionable steps they can take to protect their families, and public health messaging needs to support their informational needs. We need to focus on actionable advice.”

Shaw and the study’s authors analyzed Google search data using Semrush, a digital analytics platform, to find out what kinds of questions people are asking about PFAS in drinking water.

These substances have the attention of scientists and environmental agencies because they don’t break down easily, which is what makes them useful in consumer products but also concerning for human health. Research has linked PFAS compounds to a range of problems such as cancers, reproductive issues, immune system effects, and more. The U.S. Environmental Protection Agency says nearly everyone in the U.S. has detectable levels of PFAS in their blood.

The research team’s goal is to help create messages that use the language audiences use and answer the questions they are asking. Their findings showed that nearly half of all PFAS- and water-related searches are about how to filter or remove them from tap water. Other common queries included things like “What are PFAS in water?” and questions about PFAS in bottled or sparkling water.

Interestingly, while “PFAS” had high search volume, other more specific terms like “PFOA” or “PFOS” didn’t, and even the commonly used phrase “forever chemicals” wasn’t searched as often.

“If your public health info doesn’t use the words people are typing into Google, they’re probably not going to find it,” said Tim Holland, lead author and Ph.D. student at UW–Madison’s Nelson Institute for Environmental Studies. “Even if it’s accurate, it’s not helpful if it doesn’t show up.”

The study suggests that public health communicators could improve outreach and communication efforts by focusing on search behavior, especially for issues like PFAS, where the science is complex and the interest in taking action has increased.

“In order to best communicate PFAS, it is essential to know what people are searching for,” said Gavin Dehnert, an emerging contaminants scientist and one of the research authors with Wisconsin Sea Grant. “It allows communicators to meet people where they are to create conversation around a difficult subject.”

Other co-authors include Professor Lyn Van Swol and Rachel Hutchins from the Department of Communication Arts at UW–Madison. Other partners include UW–Madison Division of Extension, the Wisconsin Department of Health Services, the Wisconsin Department of Natural Resources, Public Health Madison & Dane County, and the UniverCity Alliance.

The study is part of a larger project coordinated by Illinois-Indiana Sea Grant that addresses PFAS knowledge gaps in the Great Lakes region.

Coastal and estuarine waters are important for human and ecosystem health. Contaminants of emerging concern (CECs) are regularly detected in these waters; however, little is known about how they are transported, where they accumulate and their final destinations. There is also a lack of research on the health risks they pose to humans and aquatic life. It is critical to continue to support ongoing monitoring efforts and to address knowledge gaps around CEC exposures, which Sea Grant has established with previous funding.

For the last four years, Congress has directed Sea Grant to collaborate with state agencies and universities to expand emerging contaminant research and monitoring. Sea Grant is pleased to announce two projects receiving approximately $984,000 in federal funding in 2024. These projects were competitively selected through an opportunity focused on CECs. The projects, detailed below, will lead regional research competitions in the Southeast and Great Lakes regions focused on addressing CEC information needs. 

2024 project descriptions:

Wisconsin Sea Grant

Quantifying the health impacts of emerging and legacy contaminants on an apex bird predator in the Great Lakes region

Federal funding: $484,400

Project lead: Christina Remucal and Gavin Dehnert

Wisconsin Sea Grant plans to sample bald eagle nestlings, game fish and water from areas in Wisconsin, Minnesota and Michigan known to have per- and polyfluoroalkyl substances (PFAS) contamination. Researchers anticipate elevated PFAS levels near historical contamination sites and expect varying levels in game fish, which could lead to updating fish consumption guidelines. This study will inform long-term monitoring and bioremediation efforts and provide insights into the potential health impacts on both humans and wildlife. The findings will benefit local communities, including tribal nations, by offering updated fish consumption recommendations and contributing to future PFAS research.

The National Sea Grant Law Center

Strengthening and expanding regional CEC initiatives to promote research-to-application partnerships

Federal funding: $500,000

Project lead: Stephanie Otts

The National Sea Grant Law Center will assess and address the risks posed by contaminants of emerging concern to local communities through an interdisciplinary approach that involves both science and outreach. They will provide funding to the South Carolina Sea Grant Consortium for research projects through their contaminants grant program and will support partnership development in the Great Lakes and Southeast regions through a competitive grant process. The expected outcomes include a better understanding of the types, prevalence and movement of contaminants in the Southeast, stronger collaboration between researchers and policymakers in both regions, the creation of research-to-application partnerships that can serve as future models, and improved integration of research into policy decisions.

State legislature’s inaction on PFAS continues

Governor Evers addresses reporters in front of empty Joint Finance committee seats.One would be forgiven if you thought that by creating a $125 million in funding to help affected communities deal with PFAS in the budget that the legislature was actually concerned about the issue and ready to act.

Unfortunately, everything they have done since they approved the state budget undercuts that conclusion. Today is the latest example in which the Joint Finance Committee refused to answer the Governor’s call for a special session to allocate this money. This ignores the urgent need to send these funds to affected communities, and the calls from dozens of citizens asking the Committee to act.

This follows more than nine months of the negotiations around SB 312, a critically flawed bill the state legislature authored to direct the DNR on how to deal with PFAS. The bill, SB 312, didn’t specifically include funding. Worse, it gave polluters too many loopholes to avoid accountability. The Governor vetoed the bill and we supported that action.

While legislators debated SB 312, state budget funds were already approved and waiting to be released to the DNR to help affected communities with water testing, research, and provide safe drinking water to Wisconsin families. The Joint Finance Committee has had the power to release these funds, but partisan political power plays are getting in the way of meaningful action.

The funds would have been released pursuant to the Department of Natural Resources’ February request to allow the following:

  • provide safe drinking water to affected communities,
  • fund more water testing,
  • help municipal water treatment facilities and businesses find alternatives for clean
  • drinking water,
  • help those with contaminated private drinking wells,
  • cover costs with disposal of contamination, and
  • support further research into the PFAS problem.

The DNR’s formal request for state budget funds has clear direction for the agency to take action to reduce or prevent exposure to PFAS chemicals in water. The funding requested is aligned with the programs in SB 312 that everyone agrees with, and which passed both houses of the legislature.

This is an urgent matter that has been waiting for action for more than 280 days. Wisconsinites deserve action, not meaningless arguments about “legislative intent,” and should not have to wait any longer for access to safe water.

PFAS News Roundup: Landmark EPA decision implements first nation-wide PFAS limit in drinking water

In Fayetteville, North Carolina on Wednesday, April 10, the Environmental Protection Agency (EPA) announced the nation’s first ever drinking water standards for PFAS. Limits will be capped at the lowest possible limit, about 4 parts per trillion. The Biden-Harris Administration concurrently announced a $1 billion investment to update water treatment plants around the country.

During a press event at the University of Wisconsin-Madison Water Sciences and Engineering Lab (WSEL) yesterday, U.S. Rep. Mark Pocan announced $963,000 in funding for a new Center of Excellence in PFAS Environmental Science.

PFAS stands for per- and polyfluoroalkyl substances, a class of chemicals used in everyday items such as nonstick cookware, food packaging and stain-repellent products. Many PFAS resist degradation and are highly mobile in the environment. As a result, these chemicals have been detected across the globe and are directly impacting drinking water, as well as fisheries. They are known to cause negative health effects in people.

“UW-Madison is one of the premier research institutions in the United States and it was an honor to secure these federal funds for them,” Pocan said, “PFAS chemicals have been detected throughout our water table, contaminating both surface and groundwater systems. This funding will be used to help conduct research to improve the quality of Wisconsin’s drinking water by removing these harmful PFAS chemical compounds from the environment.”

Sea Grant Interim Director Christy Remucal will lead the new center. She was unable to attend yesterday’s event but provided information to be shared on her behalf. “This support will allow researchers to advance actional research on PFAS. This is necessary to safeguard water quality and protect public health,” she wrote.

The center will be housed at WSEL, which currently offers the only accessible instrumentation on campus for measuring PFAS in environmental samples. In a proposal first suggesting the center, Remucal wrote, “Typical funded research projects support one researcher at a time. This funding will support multiple scientists through a collaborative Center of Excellence framework, enabling scientists to take a holistic approach to address this complex issue for the first time.”

Despite joking that he could explain the chemical makeup of the more than 9,000 PFAS and how the new center would address them, Pocan turned to others at the event during a tour of the lab to gain an understanding of current and future work.

That work will be expanded thanks to the purchase of a state-of-the-art mass spectrometer, using a portion of the new funding. Standard techniques allow researchers to now measure only about 40 different PFAS. The new instrumentation will allow researchers to study more PFAS chemicals.

The new instrument will also have high-resolution capabilities that let scientists detect and identify PFAS they currently can’t measure. This will advance the field of environmental forensics, which uses PFAS chemistry to identify the sources of contamination. This is critical for cleaning up and preventing PFAS contamination.

This investment also means researchers will increase the quantity of samples processed in the lab. Sample preparation is very time consuming and often limits how many samples can be analyzed. Through the center, Remucal plans to purchase things like automated extraction equipment that will let researchers process more samples.

In her supplied remarks, Remucal noted that researchers are making progress in learning about PFAS and coming up with solutions to address them, especially here in Wisconsin.

Remucal noted the number of researchers in Wisconsin who study PFAS has grown dramatically in the last five years. She wrote that work is ongoing to understand the fate of PFAS and how they are impacting the Great Lakes, quantify the amount of PFAS in waste materials, determine toxicity, find new detection techniques and, finally, conceive of ways to contain or remediate the chemicals.

Sea Grant is currently funding PFAS research in Lake Superior to determine if PFAS accumulate at higher levels at the surface water in foams and ice as compared to lower water depths. If that is the case, it can complicate representative sample collection. A second project will provide a quantitative understanding of PFAS moving through groundwater near Lake Michigan. A final effort is looking at toxicity and bioaccumulation of different types of PFAS in larval fish.

Through WRI, a researcher is also currently studying PFAS levels in subsistence goods relevant to Indigenous communities—walleye, maple sap and wild rice.

Another current PFAS project is quantifying PFAS export from contaminated soil to underlying groundwater aquifers, and determining how long the contaminated soil can serve as a source of PFAS in the future.

Efforts to thwart regulation of PFAS polluters move down parallel tracks

This article, first posted here, was republished with permission from Wisconsin Watch.

By Bennet Goldstein, Wisconsin Watch

Last week, a divided Wisconsin Court of Appeals upheld a lower court ruling that limited the Wisconsin Department of Natural Resources’ ability to regulate PFAS and other emerging contaminants under the state’s long-standing spills law.

Groundwater is an important source of drinking water in Wisconsin. Image credit: David Nevala

When you turn on a faucet and a stream of cool, clear water pours out, that convenience can mask where the water comes from—underground. It’s there, and in great quantities. In fact, Wisconsin has so much groundwater – 1.2 quadrillion gallons – that if it were on the surface, it would submerge Packer fans in 100 feet of the wet stuff.

Just because groundwater is out of sight, doesn’t mean it’s out of mind – or use. Where does your drinking water come from? For 70 percent of us in the state, it’s thanks to the vast stores of groundwater in aquifers that not only quench our thirst but also fuel the operations of our power plants, breweries, factories and farms. The remaining 30 percent of Wisconsinites get their drinking water from the Great Lakes.

Wisconsin has more than 800,000 private wells and in excess of 11,000 public water systems. In all, Wisconsin’s annual average water withdrawal is 1.91 trillion gallons (some of that comes from surface water, such as lakes Michigan and Superior).

With so much demand and use, groundwater is clearly valuable. And, just as in the case of surface water, we need to be responsible stewards of it. That’s worth noting as the 2024 Groundwater Awareness Week (March 4 – 10) rolls around.

One manifestation of that stewardship is the work done by our sister organization, the University of Wisconsin Water Resources Institute (WRI). WRI runs a statewide research competition through the Groundwater Research Advisory Council (GRAC). As its basic function, the GRAC ensures that Wisconsin citizens have an adequate supply of high-quality groundwater and it funds university scientists to look into current topics such as per- and polyfluoroalkyl (PFAS) in numerous Wisconsin communities and pathogens in drinking water in the Driftless Area.

An example of past impactful GRAC research looked into naturally occurring radium in drinking water serving residents of Waukesha, which led to a binational decision a few years ago to allow that city to secure water from Lake Michigan, even though it lies outside of the Great Lakes Basin.

WRI also offers a robust information transfer program highlighting the work of water scientists through news stories, podcasts and videos. Finally, the WRI supports the Wisconsin Water Library, a resource with more than 30,000 holdings of all types of water-related material free for circulation to any state resident. The library further curates and distributes water-themed learning kits for children in the K-12 educational system.

River Alliance urges Governor Evers to veto PFAS bill

River Alliance of Wisconsin urges Governor Evers to veto Senate Bill 312.

“PFAS is an urgent issue that needs to be addressed in a serious way,” said River Alliance of Wisconsin Executive Director Allison Werner. “Instead we’ve watched the state legislature play partisan games to score political points with special interest groups like Wisconsin Manufacturers and Commerce. Senate Bill 312 is not the progress we need on PFAS.”

To be clear, Senate Bill 312 does not include an appropriation of funds. Without an appropriation, the bill does not spend the $125 million dollars that the Joint Finance Committee added to the state budget. It would take additional action by the legislature to approve the costs of the programs in SB 312. In addition, PFAS are widespread and expensive to clean up. $125 million is nowhere near enough to meet the current needs of homeowners and municipalities with polluted drinking wells.

If approved, SB 312 would make it harder for the state to hold those responsible for pollution accountable, and severely limit the amount of cleanup that can be done. SB 312 would also limit grant programs only to PFAS substances for which there are standards. As we have seen with the Department of Natural Resources’ past attempts to create groundwater standards for PFAS, this legislature has little interest in such standards being created, thus also limiting any potential impact of SB 312.

For those reasons, the Governor should veto SB 312.

For real progress on PFAS, the Joint Finance Committee should approve the DNR’s request from last December that would allow them to do more testing, get clean drinking water to those who need it, and begin cleanups. The state legislature can and should also let the DNR move ahead with improving groundwater standards on PFAS in drinking water.

“When we play a partisan game with our water, all Wisconsinites lose in the protection of our health and our environment,” said Werner.
