PFAS in the drinking water of Fleetwood Boro Water System: none of the four main PFAS detected, each below the 3 to 4 ng/L reporting limit

In the latest UCMR 5 entry-point sample on August 21, 2023, none of the four most closely watched PFAS was detected: each was below the 3 to 4 ng/L reporting limit. That is below the 4.0 ng/L federal MCL for PFOA and PFOS, but the test cannot tell whether the water is above or below the 0.5 ng/L benchmark pfasnearme uses. EPA set the maximum contaminant level goal (MCLG) for PFOA and PFOS at zero because there is no level without risk. UCMR 5 results do not indicate compliance or noncompliance with the PFAS drinking water standards, and this site reports published measurements without judging health risk. This is not medical advice. If you are concerned, talk to your water system or your doctor.

The Fifth Unregulated Contaminant Monitoring Rule (UCMR 5) had every large US water system and a sample of small ones test 29 PFAS and lithium between 2023 and 2025, at each entry point to the distribution system. EPA set minimum reporting levels of 3 to 4 ng/L for PFOA, PFOS, PFNA and PFHxS and reports nothing below them. A result "below the 3 to 4 ng/L reporting limit" therefore means the lab could not quantify the compound, not that it is absent, and it is never shown here as zero.

0.5 ng/L for the PFAS-4 sum (PFOA + PFOS + PFNA + PFHxS) is the health benchmark pfasnearme applies on every page, in Europe and the United States, built from the European Food Safety Authority's tolerable intake with stricter safety choices. 4.0 ng/L is the enforceable federal maximum contaminant level for PFOA and for PFOS individually under EPA's PFAS National Primary Drinking Water Regulation (NPDWR), the US legal limit. Any PFAS-4 compound quantified under UCMR 5 (at or above 3 to 4 ng/L) is above the benchmark, so the benchmark tells you whether anything was found and the MCL tells you whether the system would have to act. EPA set the maximum contaminant level goal (MCLG) for PFOA and PFOS at zero because there is no level without risk.

EPA published the PFAS National Primary Drinking Water Regulation (NPDWR) on April 26, 2024. Systems must finish initial monitoring by April 26, 2027, tell customers about PFAS in their 2027 Consumer Confidence Reports, and comply with the PFOA and PFOS MCLs from April 26, 2029. Two proposals published on May 20, 2026 are not final: one would let systems in states where EPA holds primacy extend PFOA and PFOS compliance to April 26, 2031; the other would rescind the PFHxS, PFNA, HFPO-DA MCLs and the Hazard Index while keeping PFOA and PFOS. The rule is also before the U.S. Court of Appeals for the D.C. Circuit (American Water Works Association v. EPA, argued 2026-09-18 before Judges Millett, Pillard and Wilkins; no decision).

Yes. Pennsylvania Department of Environmental Protection (PA DEP), Bureau of Safe Drinking Water enforces MCLs under 25 Pa. Code Chapter 109 (PFAS MCL Rule): PFOA 14 ng/L (since January 14, 2023); PFOS 18 ng/L (since January 14, 2023). The federal PFOA and PFOS MCLs (4.0 ng/L) are stricter than every state MCL, so the federal line is about severity and the state line is about what is enforceable today. In this UCMR 5 sample, no compound was above a Pennsylvania MCL. State monitoring: initial monitoring 2024, quarterly compliance monitoring since 2024; statewide results summary xlsx refreshed semi-annually.

Only if Fleetwood Boro Water System (PWSID PA3060029) is your water system: check your water bill or your ZIP code page on this site, or the Berks County page. Samples are taken at the entry point to the distribution system, not at your tap. The system may have changed sources or installed treatment since this sample. PFAS treatment reported to EPA: not reported to EPA. The system's own Consumer Confidence Report, published every year, states what it measures today.

Ask Fleetwood Boro Water System for its latest PFAS results and its plan for the 2029 MCLs, read its Consumer Confidence Report (EPA's CCR finder, PWSID PA3060029), and if you want to lower PFAS at home, use a filter certified to NSF/ANSI 53 or 58 for PFOA and PFOS (reverse osmosis and activated carbon block filters; see the filter comparison linked on this page). Boiling water does not remove PFAS.

No PFAS-4 compound was quantified in any of the 6 UCMR 5 sampling events since February 6, 2023; each result was below the 3 to 4 ng/L reporting limit.
