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
PFOA5.5 ppt(MCL: 4 ppt)
PFOS6.7 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, 2024 · A study, and subsequent pilot testing, will be conducted to determine which process is recommended for the Pee Dee WTP. This study will involve pilot testing one or more of the technologies. This would allow the City to make informed choices during the design of the current expansion to enable integration of any advanced PFAS treatment process (e.g., placement of tees with blind flanges in yard piping, allocation of appropriate space). This would also allow the City to determine a cost-effective phased plan of improvements to comply with upcoming PFAS and other emerging contaminant regulations. ·
