WATER / WASTEWATER

EFFLUENT LIMITATION GUIDELINES (ELGS)

ELGs establish national technology-based regulatory limits for pollutants in wastewater discharge. The U.S EPA updates its ELG Plan every two years, and the Effluent Guidelines Program Plan 15 was finalized in January of 2023. It’s important to note that Plan 15 does not set ELGs. It identifies the industries for which ELGs will be set. Plan 15 calls for ELGs to be set for discharge from landfills. Once defined, these ELGs will be the first PFAS-related ELGs for wastewater discharge. Plan 15 also calls for more research on PFAS in wastewater discharge from textile mills as well as wastewater discharge from industry sent to publicly owned treatment works (POTW). The EPA will also continue to investigate wastewater discharge from other industries such as organic chemicals, synthetic fibers, plastics, airports, and more.

BIOSOLIDS

Roughly half of the domestic sewage sludge produced by wastewater treatment in the United States is applied to agriculture as a soil amendment. If these biosolids contain PFAS, contamination can enter the food chain and spread to local ground and surface waters.

WASTEWATER TREATMENT

Storm sewers, industrial discharge, landfill leachate, and other non-potable liquids that contain PFAS are often sent to the municipal wastewater treatment facility for processing. Unfortunately, traditional municipal wastewater treatment does not remove PFAS. In fact, it can convert PFAS precursors into terminal PFAS, further compounding a local contamination issue
