Concentrations of per-and polyfluoroalkyl substances (PFAS) in private well drinking water and serum of individuals exposed to PFAS through biosolids: The Maine Biosolids Study
Science
20 Oct 2025 | Environ. Pollut.
Individuals living near farmland where PFAS-contaminated biosolids were historically applied had elevated PFAS in their private well water and blood, especially PFOA, which showed a strong water-to-serum correlation, demonstrating that biosolids can be a major exposure source and that some people may still have high serum levels even when their current water meets standards.

Profiles of per- and polyfluoroalkyl substances in firefighter turnout gear and their impact on exposure assessment
Science
20 Oct 2025 | Environ Sci Process Impacts
Firefighter turnout gear contains varying levels of PFAS chemicals that accumulate more in older gear and the inner moisture barrier, increasing with wear, heat, and abrasion, which raises firefighters’ potential exposure risks.

Changes in the levels and predictors of per-and poly-fluoroalkyl substances in maternal plasma, relative to timelines of EPA PFOA Stewardship
Science
18 Oct 2025 | Environ. Int.
PFOS, PFOA, PFHxS, PFHpS, and Me-PFOSA-AcOH declined over time after EPA’s PFOA Stewardship Program, but other PFAS such as PFNA, PFUnA, PFDeA, PFDoA, and GenX increased especially among non-White mothers, and higher levels were linked to eating fish/shellfish and vegetables, working, and having carpet or pets during pregnancy, showing that policies reduced some PFAS but exposure sources and inequities remain.

PFAS in stormwater control measures: Removal, distribution, and long-term fate
Science
18 Oct 2025 | Water Research
Stormwater systems such as ponds and filters are not designed to remove PFAS, so most PFAS pass through the system, build up in water and sediment over time, and can transform from precursors into more toxic terminal PFAS, making stormwater a growing and often hidden source of PFAS pollution in the environment.

EPA moves to allow more PFAS in drinking water
News
15 Oct 2025 | Environment America
The current U.S. EPA is moving to weaken that rule—including rescinding the limits for four of those PFAS chemicals and delaying limits on the other two.

After finding forever chemicals in its drinking water, this Eastern Oregon city stopped testing for them
News
14 Oct 2025 | OBP
The report shows that Hermiston’s water consistently tested above the federal maximum containment level for a PFAS called perfluorooctane sulfonate.

Comparison of four PFAS mixtures assessment approaches based on extensive tap water and groundwater data
Science
13 Oct 2025 | Environ. Pollut.
Analyzing more than 1,700 U.S. water samples, the study shows that PFAS risk conclusions depend heavily on the method used, simple “sum of PFAS” limits often miss potential health concerns, while toxicity-weighted approaches like EPA-style risk assessment or relative-potency methods flag far more exceedances, frequently driven by PFOA and PFOS.

Per- and polyfluoroalkyl substances exposure in hexavalent chromium exposed workers and the effects of exposure mixtures on oxidative stress and genomic instability
Science
12 Oct 2025 | Environ Pollut
Workers in chrome-plating and similar industries are exposed to toxic hexavalent chromium alongside very high levels of PFAS such as PFOS and PFDA, and this combined exposure is linked to early signs of oxidative stress and DNA changes that may increase the risk of cancer, mitochondrial damage, and impaired DNA repair over time.

Wisconsin moves to bring PFAS limits in line with contested federal standards
News
3 Oct 2025 | Wisconsin Public Radio
Environmental advocates are urging state regulators to bring Wisconsin’s PFAS standards in line with federal drinking water standards despite an ongoing legal challenge to the federal rules.

Assessment of arsenic, cadmium, lead, mercury, and per-and polyfluoroalkyl substances concentrations in human milk and infant formula in the United States: A systematic review
Science
23 Sep 2025 | AJCN
A review of U.S. breast milk and infant formulas found that screening for harmful contaminants such as PFAS and metals are limited or outdated, while public health agencies continue to recommend breastfeeding because of its known benefits.

Per- and polyfluoroalkyl substances and the gut microbiota in infants: A scoping review
Science
23 Sep 2025 | Environ Res
PFAS exposure in infants, often through breast milk, maternal blood, or cord blood, was linked to shifts in gut bacteria diversity and changes in metabolism.

Trump EPA will defend Biden rule forcing polluters to pay for ‘forever chemical’ cleanup
News
17 Sep 2025 | The Hill
The rule in question designated two types of these chemicals as “hazardous substances,” giving the EPA more authority to clean up their contamination and require polluters to pay for it.

Per- and polyfluoroalkyl substances in agricultural systems: Human dietary exposure via beef raised on corn stover from a field with contaminated biosolids
Science
9 Sep 2025 | J Environ Qual
Cattle fed contaminated corn stover can accumulate harmful levels of PFAS in their meat and liver, creating health risks, especially for young children who eat more relative to their body weight.

A geospatial dataset of PFOS and PFOA occurrence records in China’s multi-media environments
Science
8 Sep 2025 | Nature
PFOS and PFOA, were found widely across China’s water, soil, air, food, and living organisms between 2021 and 2024, with the new geospatial dataset revealing pollution hotspots and recent declines in human blood levels linked to stricter regulations.
