Per- and polyfluoroalkyl substances in municipal solid waste incineration ash: occurrence and management implications
Science
9 Nov 2025 | Waste Manag
Municipal solid waste incineration ash from four Florida facilities contained measurable PFAS, with bottom ash showing higher levels dominated by diPAP precursors while fly ash held mostly short-chain PFAAs. These results highlight the need for stack and leaching tests as well as establishment of thresholds for some relevant PFAS to properly assess the risks of municipal solid waste incineration and ash reuse.

Life cycle assessment and life cycle costing analysis for removing per-and polyfluoroalkyl substances from landfill leachate with foam fractionation Technology
Science
22 Oct 2025 | ACS ES&T Water
Foam fractionation was identified as a sustainable and cost-effective method for removing PFAS from landfill leachate, cutting global warming potential by more than half compared to traditional one-stage systems and producing minimal hazardous waste, though energy use and short-chain PFAS removal remain challenges.

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.

Per-and polyfluoroalkyl substances (PFAS) in urban stormwater runoff: Insights from a roadside rain garden
Science
16 Oct 2025 | Water
A New Jersey roadside rain garden removed less than 1% of the 1,400–1,600 ng/L of PFAS (mainly PFBS and PFHxA) found in stormwater, showing that current stormwater systems are ineffective in removing PFAS and need advanced treatment and stronger policies.

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.

Canada’s new PFAS limits leave water utilities scrambling for costly fixes
News
29 Jul 2025 | Jaela Bernstien
Canadian water utilities are racing to assess and treat PFAS contamination after the federal government slashed drinking water limits for the chemicals and signaled plans to classify them as toxic.

A comprehensive analytical approach to monitoring selected emerging contaminant classes in sewage sludge and e-waste from Norway
Science
19 May 2025 | J. Environ. Chem. Ecotoxicol.
Norwegian researchers found that anaerobic digestion of sewage sludge converts PFAS precursors into highly mobile perfluorocarboxylic acids and leaves more persistent long‑chain PFAS, while discarded e‑waste plastics, although less contaminated, still harbor up to 176 ng g⁻¹ of PFAS, indicating that both sludge treatment and electronics recycling inadvertently leak these pollutants.

Texas bill seeking to keep toxic “forever chemicals” off farmland misses key deadline
Policy
14 May 2025
Supporters say the bill would protect farmland in Texas. Opponents say limiting PFAS chemicals in biosolids will force water utilities to look at other disposal methods, which will lead to higher utility bills.

Sewage sludge fertilizer from Maryland? Virginians say no thanks.
News
8 May 2025 | The New York Times
To protect its food and drinking water, Maryland has started restricting the use of fertilizer made from sewage sludge. At the same time, a major sludge-fertilizer maker, Synagro, has been applying for permits to use more of it across the state border, on farms in Virginia.

The cost to remove PFAS: A review of US water treatment plants
Science
14 Apr 2025 | Journal AWWA
Removing PFAS from U.S. drinking water costs between $0.75 and $8.89 per gallon in capital expenses and up to $0.28 per gallon in annual operations and maintenance, with total costs depending on plant size, location, and treatment type.

Elevated PFAS precursors in septage and residential pump stations
Science
25 Mar 2025 | Environ. Sci. Technol. Lett.
Septic systems and residential pump stations—despite lacking industrial input—were found to be significant sources of PFAS contamination, with septic systems showing especially high levels of PFAS precursors like diPAPs, underscoring the need to include precursor analysis in monitoring and to strengthen wastewater treatment strategies for decentralized systems.
