York Sewer District Files a Lawsuit Against 3M, DuPont and Others Over PFAS Contamination in Wastewater

YORK, ME, October 24, 2023 – “At York Sewer District we are proudly working to hold polluters accountable. Our rate payers are our top priority. Like so many across the State of Maine York Sewer District is concerned about the impact of these chemicals to our health, infrastructure, and finances. Therefore, we thought it critical to partner with SL Environmental on this unprecedented matter.” Says Phil Tucker, Superintendent of York Sewer District.

SLEnvironmental Law Group P.C., a New Hampshire-based law firm committed to holding polluters accountable for environmental cleanup costs, has filed a lawsuit on behalf of York Sewer District against 3M Company, E.I. DuPont de Nemours, Inc., and other manufacturers of PFAS. The case was filed following sampling of wastewater effluent and biosolids (sludge) from the District’s wastewater treatment plant serving York, Maine. Levels indicate contaminationof the wastewater system from mostly household residential sources as York has no significant industry.

PFAS are persistent toxic chemicals that build up over time when released into the environment. Due to the widespread use of these compounds in commercial and consumer products, PFAS tend to concentrate in wastewater streams, making wastewater treatment plants potential avenues of PFAS contamination. Though not currently regulated at the federal level, the US Environmental ProtectionAgency (EPA) has strongly encouraged wastewater treatment plants to test for suspected upstream PFAS sources using the latest sampling methods and effluent guidelines. A risk assessment for PFOA and PFOS in biosolids is also expected to be released by the winter of 2024.


In the absence of federal guidelines, some states have begun enacting wastewater regulations for PFAS In Maine specifically, the Department ofEnvironmental Protection has the authority to order the cleanup of PFAS contaminated sites or seek compensation from responsible parties to pay for that clean up, and a recently enacted law prohibits the spreading ofPFAS-laden sludge and sludge-derived compost as fertilizer.


Exposure to certain PFAS has been associated with several negative health outcomes in both humans and animals. PFAS has impacted surface water and groundwater throughout the country resulting in hundreds of similar suits brought forward by water providers, and mostly against the same defendants, in an ongoing multi-district litigation supervised by a federal judge in South Carolina.


SLEnvironmental Law Group has decades of experience representing municipalities and water providers across the nation in efforts to recover the costs of treating drinking water and wastewater contamination from the corporations whose products caused the pollution. In collaboration with a team of law firms, SL Environmental Law Group is handling York Sewer District’s case along with several water systems in Maine andmore than 100 entities across the country affected by PFAS.
