Three Great Lakes States at Greatest Risk as EPA Rolls Back Wetland Protections

Communities in Michigan, Minnesota, and Wisconsin are especially vulnerable to regulatory rollbacks.

On Monday, the U.S. EPA and Army Corps of Engineers proposed a set of new rules that would leave millions of acres of wetlands, small waterbodies, and ephemeral streams across the country unprotected โ€” threatening the drinking water of millions of Americans and leaving crucial habitat and floodplains susceptible to filling. These proposed changes wereโ€ฆ

Power Agency: Legislators in Illinois have introduced a bill aiming to better understand and monitor data center water pollution. Senate Bill 3830 would require data centers to identify and track all likely pollutants in wastewater that is discharged from these facilities into treatment plants. The bill would also task the state Environmental Protection Agency with analyzing and assessing this data. 

Recent investigations have shown that chemicals such as PFAS and nitrates, which are harmful to human health, are often a part of these data center discharges. The concentrations are high enough to be concerning, but their environmental and human health impacts have not been adequately studied. In September, the U.S. EPA ordered a priority review of these chemicals. 

The bill, which is included in a larger package related to artificial intelligence and data privacy, would also charge the state Department of Natural Resources with maintaining water consumption data from these facilities in a publicly accessible website. 

โ€œThis package is about responsibility,โ€ says state Sen. Rachel Ventura in a statement. โ€œResponsible innovation, responsible data practices and responsible stewardship of our communities and resources. Illinois can lead by setting smart, balanced guardrails that protect people while allowing technology to serve the public good.โ€

In Context: Ohio EPA Considers โ€˜Lowering of Water Qualityโ€™ Necessary for Data Center Growth

PFAS Declines: A study published in the Journal of Great Lakes Research suggests that concentrations of PFAS in the Great Lakes have gradually declined over the past 20 years, a trend that coincides with the phasing-out of โ€œforever chemicalsโ€ โ€” which have been shown to increase the risk for certain types of cancer and kidney and liver disease โ€” from household products. 

The study was conducted by researchers at the EPAโ€™s Great Lakes Toxicology and Ecology Division Lab in Duluth, Minnesota, a facility that last summer faced serious risks of defunding and closure amid the Trump administrationโ€™s staff and spending cuts.

The labโ€™s scientists examined frozen samples of walleye and trout from all five Great Lakes dating back 50 years. These samples had previously been studied to glean how pollutants including pesticides and mercury had traveled throughout the watershed, but the fish tissue had not been analyzed for PFAS until now. 

Though it is encouraging that PFAS concentrations have decreased, the researchers make it clear that there is no established โ€œsafeโ€ baseline for humans. In September, environmental watchdogs were alarmed when the U.S. EPA filed a court motion to vacate drinking water limits for four PFAS chemicals โ€” GenX, PFHxS, PFNA, and PFBS. In January, a circuit court denied this motion

Fish consumption advisories across the region, spurred by high levels of PFAS in waterways, remain common. In December, the Great Lakes PFAS Action Network (GLPAN) published a new online map detailing consumption and do-not-eat warnings in Michigan.  

โ€œFor many Michiganders, fishing is not just recreation โ€” itโ€™s a tradition, a way of life, a means to put food on the table,โ€ Tony Spaniola, co-chair of GLPAN, said in a statement. โ€œAs thousands of anglers head out to fish Michiganโ€™s lakes, rivers and streams this winter, this tool serves as a critical resource to ensure people know if the fish they are catching are safe to eat. People shouldnโ€™t have to comb through complicated government websites to figure that out.โ€ 

Indiana Environmental Protections: A controversial bill that would overhaul the scope of Indianaโ€™s Department of Environmental Management (IDEM) by making dozens of mandatory environmental reporting provisions optional continues to gain momentum in the Legislature. 

Senate Bill 277 passed narrowly out of the House Committee on Environmental Affairs last week in a 6-5 vote. The bill would eliminate more than 250 reporting mandates considered โ€œunnecessaryโ€ and โ€œburdensome,โ€ and would no longer require IDEM divisions of air quality, water quality, land quality, legal counsel, and program support. 

Environmental advocates have said the bill represents the stateโ€™s commitment to being no more stringent than the federal governmentโ€™s environmental regulations, many of which have been rolled back in the past year.

Pennsylvania Stream Impairment: Approximately 37 percent of Pennsylvaniaโ€™s 85,000 river and stream miles are impaired โ€” up from 34 percent in 2024 โ€” according to a draft water quality report from the state Department of Environmental Protection (DEP). Agricultural runoff, drainage from mining operations, and urban runoff were determined to be the three primary contributors to water degradation. 

In a two-hour-long meeting last week, Pennsylvaniaโ€™s House Committee of Environmental and Natural Resource Protection discussed the reportโ€™s findings with environmental scientists, county officials, and department leaders. Experts urged the committee to devote a greater number of resources to designing strategic projects, and identified state agency siloing as an impediment to watershed restoration.

โ€œHuman health is a priority for our surface water assessments and monitoring,โ€ said Jill Whitcomb, the deputy secretary of the DEPโ€™s Office of Water Programs. Roughly 80 percent of Pennsylvaniaโ€™s residents receive their water from surface waters, which is slightly above the national average.
