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
PFOA4.7 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, 2026 · The scope this project includes a pilot study evaluation of various treatment technologies to assess their ability to meet the current regulatory requirements for PFAS at WRWD. Technologies under consideration include reverse osmosis, granular activated carbon, anion exchange, Fluorosorb, powdered activated carbon, and foam fractionation. The purpose of this PFAS treatment alternatives study is to evaluate performance and conceptually size potential advanced water treatment technologies to remove PFAS compounds and comply with MCLs as well as evaluate impacts to current WTP operations and water quality. · $1.2M

Oct 22, 2024 · The WRWD WTP treats raw water from the North Tyger River and the South Tyger River. PFAS level in the raw water have been found to be greater than the MCL proposed by the EPA. Testing of finished water in WRWD's distribution system has shown similar PFAS levels, suggesting that the existing treatment process is not removing PFAS in any significant way. WRWD also maintains distribution system interconnections with Spartanburg Water and the SJWD Water District. The project scope includes planning and design of distribution system improvements to provide a 12-inch interconnection with the SJWD system in order to provide redundancy to the overall WRWD system. To date, SJWD reports no PFAS in their raw or finished water. ·
