• A critical review of perfluoroalkyl and polyfluoroalkyl substances (PFAS) landfill disposal in the United States

  Science

  25 Sep 2023 | Sci. Total Environ.

  Annually, an estimated 7.5 metric tons of PFAS enter municipal solid waste landfills, with the majority staying in the solid waste and 16% leaving through leachate and landfill gas.

• Buffalo Sewer Authority moves to remove forever chemicals from landfill leachate through firm's new tech

  News

  20 Sep 2023 | Buffalo News

  The largest landfill in New York State for years has been trucking up to 150,000 gallons of leachate per day to Buffalo for treatment at the city's Bird Island wastewater plant, where toxic levels of chemicals such as ammonia and nitrogen are removed before the water gets piped into the Niagara River.

• Comparative study of Per-and Polyfluoroalkyl substances (PFAS) removal from landfill leachate

  Science

  31 Aug 2023 | Chemosphere

  Foam fractionation and anion exchange resin treatment were the most cost-effective methods for removing >90% of PFOA and PFOS, while nanofiltration was the only method practical for short-chain PFAS removal.

• New study finds harmful forever chemicals in seemingly ‘green’ products: ‘I would not consider that biodegradable’

  News

  29 Jul 2023 | Yahoo News

  But a recent study revealed that these biodegradable alternatives might not be as environmentally friendly as they appear.

• Diffusion and partitioning of different PFAS compounds through thermoplastic polyurethane and three different PVC-EIA liners

  Science

  26 May 2023 | Sci Total Environ

  PFAS was found to diffuse through certain membranes used in landfills, potentially leading to groundwater contamination.

• 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.

• Federal PFAS Report Card

  Policy

  13 Jun 2022

  EWG has researched actions the federal government is committed to taking, or for which it faces congressionally mandated deadlines, to tackle the “forever chemicals” known as PFAS.

• 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.
