PFAS found in nearly all fish tested from four northern Illinois rivers
CHAMPAIGN, Ill. — Scientists tested nine fish species from four northern Illinois rivers for contamination with per- or polyfluoroalkyl substances, synthetic chemicals found in numerous industrial and commercial products and known to be harmful to human health. They found fish contaminated with PFAS in every one of their 15 test sites. Elevated levels of PFOS, one type of PFAS compound, were found in nearly all fish tested.
The findings are reported in the journal Science of the Total Environment.
The qualities that make PFAS desirable for industrial uses — their durability and stability under stresses such as high heat or exposure to water, for example — also make these chemicals particularly problematic in the environment and hazardous to human and animal health, said Joseph Irudayaraj, a professor of bioengineering at the University of Illinois Urbana-Champaign who led the new study.
“PFAS contain multiple carbon-fluorine bonds, one of the strongest bonds in organic chemistry,” Irudayaraj said. “Because of this, they are also very hard to break down. They persist for a long time because they are very, very stable.”
There are nearly 15,000 PFAS chemicals, according to the U.S. Environmental Protection Agency. These are classified either as short-chain PFAS, which have less than six carbon-fluorine bonds, and long-chain PFAS, with six or more of these bonds, Irudayaraj said.
Long-chain PFAS were widely used before awareness grew about the hazards of these chemicals. More recently, many industries switched to using short-chain PFAS.
“It was thought that the short-chain PFAS were less toxic, and that they could more easily degrade,” he said. “But surprisingly, that was not the case.”
Now, both types of PFAS are found in groundwater, soil and human tissues.
“About 99% of people living in the U.S. have PFAS in their system,” Irudayaraj said.
Despite a voluntary phasing out of some PFAS in industry in the U.S. and efforts to reduce PFAS pollution, these chemicals are still found in drinking water, household products, food packaging and agricultural products, he said.
The researchers focused on fish in northern Illinois rivers because they are close to urban and industrial areas. Industrial emissions and urban rainwater runoff may further contaminate local waterways with PFAS. Sport fishing is also popular across the state, including in areas inside and near Chicago. More than 666,000 fishing licenses were issued across the state of Illinois in 2020.
The researchers focused on fish in the Pecatonica River, Rock River, Sugar River and Yellow Creek from 2021-22. The team collected dozens of samples from nine species of fish, including bluegill, channel catfish, common carp, northern pike, smallmouth bass and walleye. The fish represented different levels of the food chain, from those that feed only on plants, like bluegill, to those eating other fish, such as channel catfish and northern pike.
Back in the lab, the scientists analyzed fish tissues for 17 PFAS chemicals. They found PFAS-contaminated fish in every river they tested and in every one of their 15 sampling sites. Fish from the Rock River had the highest concentrations of PFAS in their tissues. Contamination levels were highest in channel catfish, at the top of the food chain, and lowest in the plant eaters.
Four chemicals known as perfluorooctanesulfonic acids or PFOS were detected in fish from every site tested.
“These are long-chain PFAS that have been in use over the past few decades,” Irudayaraj said. “They were found in all the sites, along with a few short-chain PFAS.”
Because fish are mobile, it is problematic to tie their contamination levels to the locale where they were sampled, he said. But the finding is worrisome for people who are exposed to the water or eating the fish from these sites.
“Further studies are warranted to comprehensively evaluate the occurrence and sources of PFAS throughout the state of Illinois,” the researchers wrote. “Such information is crucial to better understand the distribution and potential risks of these compounds to the environment.”
Bioengineering is a department in the The Grainger College of Engineering at Illinois. Irudayaraj also is a professor in the Beckman Institute for Advanced Science and Technology and an affiliate of the Carl R. Woese Institute for Genomic Biology and the Carle Illinois College of Medicine at the U. of I.

I’m grateful for Illinois legalizing physician-assisted suicide | Letter
When I became disabled due to a traumatic injury at 17, the first thing I felt was a tremendous loss of control over my life. I’ve worked since then to regain and retain it.
It’s why I embrace the fundamental principle of the independent living movement and the disability rights and justice movement – that all of us have and deserve the right to self-determination and to make our own decisions, including decisions about the services and care we receive.
That is why I am grateful to Gov. Pritzker and the Illinois General Assembly for passing a new law that legalizes Medical Aid in Dying (SB 1950), the End of Life Options Act.
Death elicits fear. It certainly represents the ultimate loss of control. We all hope that it will be peaceful and without great suffering.
For many of us who have experienced marginalization because of disability or age, poverty, race, and other socially imposed constructs, we fear being devalued or dismissed in decision-making in systems, including in chronic or acute health care situations. This law relates specifically to terminal illness, not chronic or acute care. And disability should not be conflated with terminal illness.
The ability to control the decision-making process in the End of Life Options Act is detailed and robust. It’s a high bar to be eligible to participate.
It requires you to be able to be fully in control of the decision-making process and of the administration of medication, only when you have a prognosis of less than six months or less to live. It requires consultation with at least two different medical professionals. It has strong provisions that prevent anyone from assisting or exerting undue influence, including any person to whom you might have already given health care power of attorney.
Medical aid in dying is a trusted and time-tested medical practice that is part of the full spectrum of end-of-life care options, including hospice and palliative care. People move across the country to access it. Those with terminal illness who are unable to relocate because of disability or income need the equity that comes from being able to access options where we live.
As someone who has learned to never take it for granted, I want this right to self-determination to extend through the final days of my life if I should face a terminal illness.
I am grateful that Illinois has joined the many other states who support this additional end of life care option for all who are facing terminal illness.

Power drip: Electricity shortages coming to Illinois
A recent study published by three state agencies warns electricity shortages are coming to Illinois.
The shortages will start in PJM Interconnection’s regional transmission system by 2029, with the shortage hitting Illinois’ ComEd territory (which is within PJM) beginning in 2030, and then kicks in hard by 2032.
Capacity shortages in downstate Ameren’s territory are expected to begin in 2031 and escalate through 2035, when the stuff hits the fan. Ameren is in the Midcontinent Independent System Operator’s, or MISO’s, regional transmission network.
The report acknowledges that some fossil fuel power plants might have to remain open at least in the short-term, despite the state’s ambitious climate goals. A bill passed the legislature in October to facilitate that.
The Illinois Power Agency, the Illinois Environmental Protection Agency and the Illinois Commerce Commission conducted the study.
Massive increases in power needs by data centers are the “primary driver” of increased electricity demand, according to the report. Those gigantic increases were not foreseen when the state designed its landmark clean energy law in 2021 requiring net-zero carbon energy by 2045.
Coal and gas plants “are planned to retire across both [PJM and MISO] due to age, economics and emissions limits,” the new report points out, and that’s also contributing to the coming shortage.
Also problematic is the fact that new gas plant equipment takes 5-7 years to purchase and install, and the plants face additional siting and permitting barriers. Wind and solar face serious obstacles as well..
All that results in this warning from the three state agencies: “These conditions create a credible risk of regional capacity shortfalls that will impact Illinois’ future ability to import power during critical hours and may cause reliability issues in Illinois even if Illinois market zones have enough capacity to meet their [resource adequacy] requirements as determined by [PJM and MISO].”
Translation: Even if Illinois produces more power, we still might be in big trouble because other states are facing similar problems.
In the ComEd region alone, projected load growth “drives a 24% increase in resource adequacy requirements between 2025 and 2030, which contributes to growing dependence on external capacity even before the onset of an outright shortfall in 2032.”
However, the report claims, “The state can successfully navigate both near-term reliability risks and longer-term decarbonization goals through a diversified resource strategy.” That strategy includes “the continued use” of fossil fuel plants “even as their energy output declines with higher renewable penetration.”
Another study will be published in 2027. The report said that study will likely include increased renewables and battery storage but will also look at “delays and/or reductions” to emissions requirements allowed by the Clean and Reliable Grid Affordability Act, which passed in October.
That’s cutting it awful close. Some business groups, including the Illinois Manufacturers’ Association, want the state to act immediately to keep existing fossil fuel plants open.
Forty years ago, Illinois had some of the highest electric utility rates in the Midwest. Then, after the state deregulated the industry, our costs became far more competitive and the state used those low rates to lure new businesses.
But then abundant supply (encouraged by deregulation) pushed rates to a point where some nuclear power plant owners couldn’t afford to operate, so Illinois had to force consumers to subsidize the plants.
Then, with the gigantic data center and resulting artificial intelligence booms, along with aging plants going offline, electricity started becoming scarce again and rates have gone up.
Unilaterally cutting off data center expansion here won’t work because the state is part of those two large regional power distribution networks. They’ll just cross the state lines and continue consuming our juice.
Maybe the AI bubble will burst. But what is clear is that Illinois laws have to be flexible enough to deal with the unexpected, and that obviously hasn’t been the case
Yes, coal plants were closing anyway because they aren’t cost competitive. Same with some gas plants. But government operates so slowly that few have confidence it can turn the ship around in time to avert a coming shortage.
Everyone is pointing to the recently passed Clean and Reliable Grid Affordability Act as a possible solution because it gives the state more pollution control flexibility, but even that may not be adequate if there’s not enough will at the top to make extra sure we don’t enter a crisis stage.
The governor has expressed confidence that the state can handle this. But businesspeople are rightly freaking out.
Climate change is real. But if the lights don’t go on, or the local factories close, nobody will care about excuses. They’ll just want it fixed.
