Is there PFAS in Washington Court House tap water?

In EPA's UCMR 5 testing of WASHINGTON COURT HOUSE PWS (2024-10-02 to 2025-07-07): none of the 29 PFAS tested detected. "Not detected" means below the lab's reporting limit, not proven zero.

What are the federal PFAS limits?

EPA's 2024 drinking-water rule set maximum contaminant levels of 4.0 ng/L for PFOA and for PFOS, and 10 ng/L for PFHxS, PFNA and HFPO-DA (GenX). In May 2026 EPA proposed keeping the PFOA and PFOS limits, with the option of until 2031 to comply, and rescinding the other three. Until a final rule, all five limits apply. Results above them today are above the limits in force.

How do I remove PFAS from my tap water?

Reverse-osmosis systems and filters certified to NSF/ANSI 53 or 58 for PFOA/PFOS reduction are the proven options at the tap. Check the certifier's listing (NSF, WQA or IAPMO) for the exact model, and replace cartridges on schedule.
