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.

Assessment of trifluoroacetic acid in tap water from Besançon (France) and bottled water from France, Italy, and Romania
Science
14 Oct 2025 | Discover Water
TFA, an ultra-short chain PFAS, was found in 100% of tap water samples from Besançon (540–3,800 ng/L, average 1,164 ng/L) and in most bottled waters at lower levels, showing that tap water is a major source of exposure and that this persistent, unregulated chemical needs monitoring and inclusion in drinking water policies.

Current knowledge about per-and polyfluoroalkyl substances (PFAS) in the atmosphere: Fate, analytical methods and research priorities
Science
13 Oct 2025 | Chemosphere
PFAS can escape into the air from factories, firefighting foams, landfills, and wastewater plants, move long distances in gases and tiny particles, cycle back through rain and sea spray, accumulate indoors, and expose people by breathing or skin contact even far from the source.

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.

From carboxylates to chlorinated sulfonates: Contrasting fate and treatment prospects of GenX and F53B in WWTPs
Science
13 Oct 2025 | Science of The Total Environment
In wastewater systems, GenX was found to largely persist in the aqueous phase with minimal degradation, while F-53B partitions to sludge and undergoes limited breakdown, and advanced treatments like UV with sulfite or electrochemical oxidation outperform conventional processes, though byproducts and limited field data remain concerns.

A review of the key impacts of deforestation and wildfires on water resources with regard to the production of drinking water.
Science
12 Oct 2025 | Hydrology
Deforestation and especially wildfires can release pollutants into water, but wildfires pose an added threat because firefighting foams and burn residues introduce PFAS that contaminate both surface water and groundwater, making drinking water treatment far more difficult and costly.

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.

An unwanted hitchhiker: Assessment of per-and polyfluoroalkyl substances (PFAS) in vehicle cabin air conditioner and engine filters
Science
10 Oct 2025 | Analytical Methods
Car cabin air filters were dominated by diPAPs and long-chain PFCAs (like PFOA, PFNA, and PFDA), showing far higher PFAS levels than engine filters, which mainly contained fluorotelomer sulfonic acids and some PFCAs, indicating that vehicle interiors are a significant source of PFAS exposure.
