Evaluation of fluorochemical leaching from lithium-ion batteries under simulated solid waste landfill conditions
Science
3 Dec 2025 | Environ. Sci. Technol.
Lithium-ion batteries may release multiple fluorochemicals, including PFAS such as 2,4-difluorobenzoic acid and several fluorinated electrolyte additives, under simulated landfill conditions, suggesting that end-of-life battery disposal may introduce additional PFAS sources into landfill leachate.

Maine was first to ban spreading PFAS-contaminated sludge on farmland. Now sludge is filling up landfills.
News
28 Nov 2025 | Sentient Health
“When we think about policy change around PFAS in commercial products and our waste stream, we tend to focus on economic impacts,” said Adam Nordell, a farmer who had to close his operations a few years ago over high PFAS contamination and who now advocates about farmland contamination risks. “But at the end of the day, it’s a story about human health.”

Nationwide estimate of volatile per-and polyfluoroalkyl substance (PFAS) emissions from US landfills via landfill gas
Science
17 Nov 2025 | Environ. Sci. Technol.
Landfill gas was found to contain notable levels of volatile PFAS, particularly 6:2 and 8:2 FTOH, suggesting that landfills may act as an underrecognized source of atmospheric PFAS emissions and raising policy concerns due to major uncertainties in how effectively these compounds are managed.

Per- and polyfluoroalkyl substances (PFAS) profiles in primary and secondary landfill leachates: Indications of transformation, liner interactions, and other PFAS sources
Science
24 May 2025 | J Hazard Mater
Tests at three modern, double‑lined Florida landfills showed that the supposedly isolated liquid beneath the main liner still contained thousands to tens of thousands of nanograms‑per‑litre of assorted PFAS, often rivaling or exceeding levels in the primary leachate, revealing that “forever chemicals” can slip through liners, transform, and build up despite today’s best landfill safeguards.

National Assessment of PFAS in Landfill Leachate in China: Non-Negligible Ultrashort-Chain Components and Socioeconomic Impacts
Science
20 May 2025 | Environ Sci Technol
A nationwide survey of 70 Chinese landfills found that their wastewater holds sizable amounts of PFAS, mostly newer ultrashort‑chain chemicals, releasing about 419 kg into the environment each year and underscoring the need for stricter waste controls.

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.

Evaluating the hypothesis of per-and polyfluoroalkyl substances (PFAS) presence in HDPE geomembranes
Science
22 Apr 2025 | J. Hazard. Mater. Adv.
Ultra-short-chain PFAS (specifically PFPrA) were detected in all tested HDPE geomembranes used for waste containment—potentially leading to elevated PFAS concentrations in landfill leachate.

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.

Leaching profile of per-and polyfluoroalkyl substances from selected e-waste components and potential exposure pathways from discarded components
Science
17 Mar 2025 | J Hazard Mater
Discarded electronics like cables, keyboards, monitors, and circuit boards can release harmful PFAS—especially PFBA, PFHxA, PFOA, and PFOS—into the environment through leaching, highlighting e-waste as a significant but underrecognized source of long-term contamination and exposure risks.

PFAS opportunities coming as Trump enters office, waste executives say
Policy
25 Nov 2024
Executives said the incoming Trump administration could roll back the EPA’s hazardous substance designation for PFAS, but they expect continued business opportunities with the material.

Release of Volatile Per- and Polyfluoroalkyl Substances from Plant Fiber-Based Food Packaging and Municipal Solid Waste to Gas under Simulated Landfill Conditions.
Science
19 Nov 2024 | Environ Sci Technol
High-fluorine food packaging released 62–800 ng PFAS per gram into the air, dominated by 6:2 fluorotelomer alcohol, with early decomposition stages accounting for most of the emissions.

A Pilot Study of Bis-perfluoroalkyl Sulfonimides in Dust from E-waste and Urban Regions
Science
12 Nov 2024 | Environ. Sci. Technol. Lett.
Dust samples from e-waste recycling sites showed significantly higher levels of bis-FMeSI (median 12 ng/g) compared to surrounding and urban areas, indicating e-waste recycling as a major source of environmental release for this emerging PFAS, which poses potential ecological and human health risks.

Permeation of Per-and Polyfluoroalkyl Substances (PFAS)-Laden Leachate in Landfills as an Outcome of Puncture Failures of High-Density Polyethylene Geomembranes
Science
12 Nov 2024 | Environmental Pollution
Puncture failures in high-density polyethylene landfill liners increase the permeation of hazardous PFAS-laden leachate. Short-chain PFAS, due to their surfactant properties, significantly enhanced permeation rates, highlighting concerns over environmental contamination if proper landfill protections are not maintained.

City-scale Impacts of PFAS from Normal and Elevated Temperature Landfill Leachates on Wastewater Treatment Plant Influent
Science
4 Nov 2024 | J. Hazard. Mater.
Elevated temperatures in landfills can significantly increase PFAS concentrations and precursors in leachate compared to normal conditions, indicating diverse and complex PFAS sources impacting wastewater treatment plants and underscoring the need for further research on their environmental impact.

Decontamination of landfill waste leads to increase in toxic chemicals, says study
News
4 Nov 2024 | The Guardian
Processes intended to decontaminate noxious liquid landfill waste before it enters rivers and sewers have been found to increase the levels of some of PFAS, a study has shown.
