A review of the occurrence, transformation, and removal technologies for the remediation of per- and polyfluoroalkyl substances (PFAS) from landfill leachate
Science
8 May 2023 | Chemosphere
This paper critically reviews various treatment techniques for PFAS removal in landfill leachates and provides guidance for promoting environmental protection and sustainable development of PFAS remediation in landfill leachate.

Per-and Polyfluoroalkyl Substances (PFAS) Distribution in Landfill Gas Collection Systems: Leachate and Gas Condensate Partitioning
Science
31 Jan 2023 | J. Haz. Mat.
PFAS identities and concentrations were compared in landfill gas condensate and leachate within gas wells, including more semi-volatile PFAS rarely measured in water matrices.

Presumptive Contamination: A New Approach to PFAS Contamination Based on Likely Sources
Science
12 Oct 2022 | ES&T
A contamination model was used to create a map of presumptive PFAS contamination sites in the United States, identifying more than 57,000 sites including industrial facilities, wastewater treatment plants, current or former military sites, and airports.

Per-and polyfluoroalkyl substances in the atmosphere of waste management infrastructures: Uncovering secondary fluorotelomer alcohols, particle size distribution, and human inhalation exposure
Science
29 Jul 2022 | Environ. Int.
PFAS were prevalent in the air and in particulate matter near landfills and wastewater treatment plants, and modeling demonstrated that fine and ultrafine particles may carry PFAS into the lung alveoli.

PFAS use in electronic products and exposure risks during handling and processing of e-waste: A review
Science
24 May 2022 | J Environ Manage
The wide use of PFAS in electronics presents a likely exposure source to workers at electronic-waste disposal sites given that PFAS have been detected in environmental and human samples near waste processing sites.

Pilot-Scale Continuous Foam Fractionation for the Removal of Per-and Polyfluoroalkyl Substances (PFAS) from Landfill Leachate
Science
17 May 2022 | ACS ES&T Water
Foam fractionation was found to remove PFAS from landfill leachate, with higher removal efficiencies for long-chain PFAS compared to short-chain PFAS.

Widespread Occurrence of Non-Extractable Fluorine in Artificial Turfs from Stockholm, Sweden
Science
19 Apr 2022 | Analytical Chemistry
Results suggest the use of polymeric organofluorine in artificial turf, such that the production, end-of-life, and microplastic concerns are greater than the risk to users.

Two area landfills show high PFAS levels in leachate
News
9 Apr 2022 | The Finger Lakes Times
In testing that took place four years ago, high levels of polyfluoroalkyl substances, or PFAS, and several related compounds were found in leachate originating from the Seneca Meadows and Ontario County landfills.

Per- and Polyfluoroalkyl Substances (PFAS) in Facemasks: Potential Source of Human Exposure to PFAS with Implications for Disposal to Landfills
Science
6 Apr 2022 | ES&T
Preliminary findings indicate that wearing masks treated with high levels of PFAS for extended periods of time can be a notable source of PFAS exposure and have the potential to pose a health risk.

Scientists sound alarm at US regulator’s new ‘forever chemicals’ definition
News
5 Apr 2022 | The Guardians
The EPA responsible for protecting the public from toxic substances is working under a new definition of PFAS “forever chemicals” that excludes some of their widely used compounds.

Municipal solid waste incineration (MSWI) ash co-disposal: Influence on per- and polyfluoroalkyl substances (PFAS) concentration in landfill leachate
Science
31 Mar 2022 | Waste Manag
PFAS concentrations in leachates are higher when PFAS-rich unburned wastes are disposed of alongside incineration ash, even if the unburned fraction is small.

PFAS Complicates the Problem of Handling ‘Garbage Juice’ From State’s Only Landfill
News
28 Oct 2021 | VTDigger
Leachate is most often disposed of at municipal sewage-treatment plants — but those plants have no way of treating PFAS and other “forever chemicals” that are in products that wind up in the landfill.
