Is there PFAS in Gcwsd Waccamaw Neck (sc2220010) water?
Yes. EPA's final UCMR 5 results show Gcwsd Waccamaw Neck (sc2220010) averaged 6.1 ppt of PFOS at its worst sampling point, 1.5 times the EPA limit of 4 ppt.
Gcwsd Waccamaw Neck (sc2220010) is a public water system drawing on surface water, based in Pawleys Island, South Carolina, serving about 41,300 people, including Murrells Inlet, Pawleys Island. Under EPA's Fifth Unregulated Contaminant Monitoring Rule it was tested for 29 PFAS and lithium 4 times across 1 sampling point between Oct 2024 and Aug 2025.

What the EPA limits mean here
In April 2024 EPA set enforceable limits of 4 ppt for PFOA and PFOS, 10 ppt each for PFHxS, PFNA and GenX, and a hazard index of 1 for mixtures. Utilities were given until 2029 to comply. In May 2026 EPA proposed keeping only the PFOA and PFOS limits and moving that deadline to 2031. Until that proposal is final, the 2024 limits stand.
Compliance is judged on a running annual average at each entry point, so we show the average at this system's worst sampling point next to its single highest result. UCMR 5 results do not by themselves put a utility in or out of compliance.
What you can do at home
Two routes work for PFAS. For drinking and cooking water only, a reverse osmosis system certified to NSF/ANSI 58 with a PFOA/PFOS reduction claim is the cheapest proven option. To treat every tap and shower, a whole-house carbon system with enough contact time works, but check that the maker has PFAS test data, not just a marketing claim. See the best filters for PFAS and how PFAS removal works.
