U.S. Rep. Mark Pocan announcing a nearly $1 million investment in PFAS research. Photo by Wisconsin Sea Grant.
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 a new Center of Excellence in PFAS Environmental Science. Photo by Wisconsin Sea Grant.
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.

Every five years, the University of Wisconsin Water Resources Institute (WRI) is evaluated to determine eligibility for continued support under the federal Water Resources Research Act of 1984, which is administered by the U.S. Geological Survey (USGS).
WRI recently received the results of that review of 2016-20 research, student support and information transfer. The headline is the USGS found that WRI is “performing at an outstanding level.”
The USGS review panel assessed WRI’s effectiveness in using its federal grant, as well as required matching funds, which come from the state of Wisconsin. The panel also called out notable features in how WRI operates:
“We work every day to leverage our federal and state funding effectively to help communities across Wisconsin, and it is truly a collective team effort,” said Jennifer Hauxwell, WRI’s research director. “From the dozens of researchers at Wisconsin universities across the state who step up to address our shared water challenges to institute staff who coordinate our research program, create student training opportunities, manage the distribution of funding and communicate stories and archive findings, we are so very grateful. We still have a lot to learn about Wisconsin’s water resources and community needs, and we look forward to tackling future challenges and opportunities together.”
WRI is one of 54 national water research institutes. For 60 years, it has been a locally focused state and federal partnership supporting unbiased research and information transfer, which leads to safeguarding Wisconsin’s water quantity, quality and management. Some of the research projects supported during this evaluation period looked at naturally occurring contaminants like strontium, radium and manganese. Other projects explored land use practices and the resulting levels of nitrate in groundwater.

Discovery is part of first-ever study of viruses in healthy fish across the state.
Researchers at the University of Wisconsin-Madison have detected a suite of new viruses in five species of Wisconsin sport fish. Although none pose a threat to human health, one is a type of coronavirus usually associated with birds. It was found in healthy walleyes from Wisconsin lakes. The finding is part of a Wisconsin Sea Grant-funded study of the natural diversity of viruses (or virome) of fish in Wisconsin and is the first project of its kind in North America.

Tony Goldberg, a professor in the Department of Pathobiological Sciences, said his research group identified 19 viruses in blood samples from 103 Wisconsin bluegills, brown trout, lake sturgeon, northern pike and walleye. Seventeen of the 19 viruses were new to science. Among them was the first fish-associated coronavirus from the Gammacrononavirus genus, which differs from the type of virus that causes COVID. It was present in 11 out of 15 walleyes sampled by the Wisconsin Department of Natural Resources (DNR).
While the findings are novel, Goldberg stressed that anglers should not be worried. “None of these viruses can infect people. It’s not a risk for people to catch, handle and eat fish because of these viruses. There’s no evidence that these viruses are causing any problems. They may just be part of the natural ecosystem of these fish,” he said.
The results were recently published in the journal “Pathogens.” Of the different species of fish sampled, lake sturgeon blood contained the most viruses (97% of samples), with brown trout samples showing the least prevalence (6%).
Regarding the coronavirus found in walleye, Goldberg said, “There’s an important poultry disease called infectious bronchitis that is caused by a relative of this new virus, but this is the first example in fish and it is an honest-to-goodness coronavirus.”
This virus survey builds on previous Sea Grant-funded research in which Goldberg studied viral hemorrhagic septicemia in fish. The DNR took blood samples from healthy fish across Wisconsin to test for viral hemorrhagic septicemia antibodies. They saved the blood and used it for this current study on the viromes of Wisconsin fish.
The findings will aid fishery managers when they routinely test the health of fish about to be released into state lakes from hatcheries or for fish that are being shipped out of state.

“This is a huge problem for fisheries managers that happens all the time,” Goldberg said. “We recently had a case where there were thousands of muskies that were ready to be released and they came back with an unknown virus. So, do you release them? Do you just keep them there? Do you kill them all? Maybe there are viruses out there that are a normal part of the ecosystem and they just infect a lot of fish, but they don’t cause disease.” This study’s findings will help managers decide what is normal and what is concerning in terms of fish viruses.
Goldberg said that one thing anglers can do to ensure fish viruses aren’t spread is not to transport fish between water bodies “If you move a fish from one water body to another, you’re moving everything that lives on and in that fish, and potentially causing problems,” he said.
As a follow-up, Goldberg’s collaborators at the U.S. Fish and Wildlife Service have designed specific tests for the various viruses and the team will test a larger set of fish blood samples from around Wisconsin. They will map the viruses so that fisheries managers can tell what’s normal for a particular watershed and whether stocking can or should not proceed.
He also plans to develop a “Fish Get Sick, Too,” educational program. Goldberg said that fish are “animals, like anything else, and they get sick, too. I think if people were more aware of that, it might help reinforce some of the best-handling practices we do for catch-and-release fishing, some of the harvest practices, and food safety things we do.”
Other members of the research team include Charlotte Ford and Christopher Dunn with the UW-Madison Department of Pathobiological Sciences; and Eric Leis and Isaac Standish with the U.S. Fish and Wildlife Service, La Crosse Fish Health Center.

CHICAGO, IL (March 25, 2024) – Last week on World Water Day, the Alliance for the Great Lakes, Ocean Conservancy, Illinois Environmental Council, and Loyola University scientists held a press conference with partners at the Museum of Science and Industry to discuss protecting the Great Lakes and waterways from the environmental and health risks of microfiber pollution. The Great Lakes provide drinking water for more than 30 million people and are home to diverse and increasingly threatened wildlife. However, the Great Lakes are in the midst of a plastic pollution crisis, with plastic waste increasingly accumulating in our waterways. To address this issue, Illinois lawmakers have introduced a bill that would require microfiber capture devices on all washing machines sold in Illinois by 2030.
“What happens in Illinois impacts the ocean – whether through the Great Lakes, whose water flows through the St. Lawrence Seaway to the Atlantic, or through the Mississippi River flowing into the Gulf of Mexico. Microplastics can even be carried by evaporated water and spread through our weather systems around the world. Washing machines are a major contributor to plastic microfiber pollution, and Ocean Conservancy is proud to support this bill to stop microplastics at the source,” said Jeff Watters, Vice President, External Affairs at Ocean Conservancy.
“For over 30 years, Alliance for the Great Lakes Adopt-a-Beach volunteers have been on the front lines of keeping litter off our beaches and out of the Great Lakes by removing over half a million pounds of litter from shorelines since 1991. Most of the litter collected is composed either partially or fully of plastic. The good news is that if we act now, we can stop the pollution before it makes its way into our waterways through simple washing machine filters like those used in dryers. Our dedicated volunteers shouldn’t be the only means to keep plastic pollution out of the Great Lakes. We need smart policies to reduce microplastic pollution, which is why we fully support Illinois House Bill 4269,” said Molly Flanagan, Chief Operating Officer & Vice President for Programs of the Alliance for the Great Lakes.
“Our research group has been studying litter in our waterways for over 10 years. The vast majority of the trash we find is plastic, and increasingly, microfibers are the most common microplastic in our waterways. Preventing pollution at the source is critical; washing machine filters are a simple and cost-effective solution. This approach is important and can make meaningful improvements to reduce pollution,” said Dr. Tim Hoellein, Associate Professor, Loyola University, Director Aquatic Ecology Lab.
Plastic microfibers that come from plastic-based textiles and clothing are of growing concern. Microfibers are the most prevalent form of microplastics in environmental samples and represent over 90% of microplastics ingested by marine animals. In animals, ingestion of microfibers has been shown to reduce food consumption, reduce energy for growth, alter gene expression, and block digestive tracts.
In many cases, microfibers that are shed from clothing during household and commercial laundering escape wastewater treatment plants (WWTPs) and flow with the discharge into our waterways. An existing technology, washing machine microfiber filters, have been shown to be a cost-effective solution that can capture up to 90% of microfibers from each load of laundry, leading to a significant reduction in microfibers in wastewater treatment plants.
