One or more PFAS compounds exceed EPA Maximum Contaminant Levels. This is not a current violation — the federal compliance deadline is April 2029 (a proposed extension to 2031 is not final). These are UCMR 5 results from 2023 to 2025; the system may have installed treatment since.
Key contaminants vs MCL
PFOA5.6 ppt(MCL: 4 ppt)
PFOS5.3 ppt(MCL: 4 ppt)
EPA MCL: 4 ppt (parts per trillion) for PFOA and PFOS individually. Compliance deadline: April 26, 2029 under the current rule.

Jun 26, 2026 · The PFAS treatment project would install post-filter adsorption treatment technology at the Purrysburg WTP. The project would consist of a dedicated new building and would house the media contactors and related equipment required such as influent and backwash pumps, media delivery and storage facilities, cartridge filters, associated piping and valves, necessary chemical feed and storage monitoring equipment, and backwash water storage. The new building would include HVAC, electrical and other utilities. Additional project costs include the initial granular activated carbon media fill for the post-filter adsorption technology. The size of the improvements would be scaled to the Purrysburg WTP which will be rated to treat up to 30 million gallons per day. · $55.2M
