Global inventory of fluoropolymer production plants and their associated PFAS environmental contamination
Science
8 Apr 2026 | Environ Sci Technol
A global assessment of industrial sites manufacturing fluorinated polymers indicates that releases of perfluoroalkyl carboxylic acids, perfluoroalkyl sulfonic acids, and ether-based alternatives are commonly detected in air, water, soil, and biota, often at elevated levels and across broad distances.

Local scientists to host press conference on PFAS, forever chemicals
News
20 Mar 2026 | Tallahassee Democrat
Ron Saff, an allergist, and Don Axelrad, a retired Florida A&M professor of environmental health sciences, are planning to host a press conference outside of City Hall on March 23 at 11 a.m. to discuss PFAS that the two have found in local water supplies.

Atmospheric transport and deposition of PFAS in East Antarctica: Evidence from snow transect measurements and a multidecadal record
Science
20 Mar 2026 | Science Advances
PFOA, PFNA, TFA, PFPrA, and HFPO-DA were found to persist in Antarctic snow due to long-range atmospheric transport and ongoing formation from precursor chemicals.

Louisville Found PFAS in Drinking Water. The Trump Administration Wouldn’t Require Any Action.
News
12 Feb 2026 | Louisville Public Media
The GenX levels Louisville found in December 2024 were 15 times the reading from the previous month: 52 parts per trillion versus 3.4 ppt.

Wisconsin moves forward with PFAS limits that Trump EPA is rolling back
News
2 Feb 2026 | Wisconsin Public Radio
“We certainly hope that the state and the federal government will provide the support to allow our utilities to do the projects and build the facilities and do the treatment where it might be necessary to meet these regulations as quickly as possible,” Smith said.

As EPA tries to loosen PFAS rules, NC regulators inch toward statewide protections
Policy
9 Jan 2026
Members of the Environmental Management Commission expressed the need for some urgency in moving forward with the development of statewide rules on Thursday. The group took up two sets of “monitoring and minimization rules”: one for three types of PFAS – PFOS, PFOA and GenX – and another for 1,4-Dioxane.

Fate, bioaccumulation, and toxic responses of PFOA, PFOS, and GenX in the paddy soil-rice system across the full growth cycle
Science
1 Jan 2026 | J Hazard Mater
Analysis of a full growth cycle study in paddy soil suggests that PFOA, PFOS, and the replacement PFAS GenX may disrupt rice growth and induce oxidative stress. GenX is showing greater upward movement into edible tissues, highlighting potential food-chain relevance and informing proposed soil safety thresholds for rice cultivation.

More cities are seeing PFAS pollution in drinking water. Here’s what Louisville found
News
1 Dec 2025 | NPR
At the Louisville Water Co., the team's calculations eventually showed that the December 2024 spike in GenX levels corresponded to publicly-available data from Chemours, about its chemical discharges into the Ohio River.

Regrettable for whom? GenX chemicals as a case study in detrimental chemical substitution
Science
18 Nov 2025 | Environ. Sci. Policy
The example of GenX’s substitution for PFOA shows how structural factors in the US chemical regulatory system, including data gaps, permissive loopholes, and limited oversight, can enable detrimental chemical replacement. These findings underscore the need for stronger policies that prioritize public health.

Asymmetrical contamination of anionic PFAS across global freshwater reservoirs
Science
18 Nov 2025 | Water Research
Freshwater reservoirs across Asia, North America, Europe, Africa, and Oceania show three distinct PFAS contamination stages, including PFOA-dominated, PFOA plus PFOS co-dominated, and short-chain PFBA-dominated profiles, which together point to the need for more coordinated global multi-media PFAS monitoring and governance.

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.

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.

Comparing in-home and bottled drinking water quality: regulated and emerging contaminants in rural Central Appalachia
Science
3 Sep 2025 | J Water Health
PFAS were present at very low levels in some in-home, spring, and bottled water, measured by LC-MS/MS with reporting limits down to 0.015 ppt, bottled water showed total PFAS up to 2.354 ppt with no individual PFAS exceeding the April 2024 EPA MCLs, and only one tap sample contained GenX at 0.136 ppt.

Per-and polyfluoroalkyl ether acid (PFEA) concentrations in indoor dust are higher in homes closer to a fluorochemical manufacturing facility
Science
31 Mar 2025 | Environ. Sci. Technol.
Homes closer to a PFAS manufacturing facility in North Carolina had significantly higher levels of toxic PFAS—including GenX and Nafion byproducts—in indoor dust, suggesting that air emissions from the facility may be a major source of exposure, especially for children.
