PFAS IN LANDFILL LEACHATE

PACE® WAS ONE OF THE FIRST LABS IN THE U.S. TO SUPPORT REPONSIBLE WASTE MANAGEMENT PRACTICES WITH TESTING SERVICES FOR PFAS IN LEACHATE.
(UNDER)LINING THE ISSUE
Leachate from unlined or poorly lined landfills, commonly found in industry and on construction sites, can contaminate local groundwater and surface water. Since PFAS don’t degrade naturally, contamination may continue for decades after the landfill has been decommissioned.
Municipal landfills are typically well lined, so leachate doesn’t leak directly into the surrounding environment. Instead, the leachate is often sent to the local wastewater treatment plant for processing. Unfortunately, traditional wastewater treatment processes do not remove PFAS and can convert PFAS precursors into terminal compounds
SOURCES OF PFAS IN LANDFILL
Both industrial and municipal landfills are easily contaminated with PFAS. Here are just a few common sources.
Construction Waste
Roofing, carpeting, wiring, solar panels, and more may contain PFAS to make them more durable.
Food Packaging
PFAS is often added to paper and paperboard food packaging to make it grease resistant.
Discarded Clothing
PFAS has historically been used to weather-proof clothing or to make it flame retardant.
Industrial Waste
PFAS may be used in industrial applications as a lubricant or to increase mechanical durability.
Fluorinated Plastics
PFAS added to plastics can prevent seepage and block noxious fumes and unpleasant odors.
Household Garbage
Cosmetics, non-stick cookware, cleaning products and other waste may contain PFAS.
REGULATORY LANDSCAPE FOR LEACHATE
Many of the high profile PFAS lawsuits have involved industrial landfills, so even without specific laws targeting leachate, risk mitigation requires a focus in this area. In addition, the EPA plans to complete a detailed study on PFAS discharge from landfill by fall of 2022. They will use this data to inform future rulemaking.
