Does Fuquay-Varina, NC Water Have PFAS? What EPA's Testing Found

Triangle Waterworks · informational guide

Direct answer: Yes. EPA's UCMR5 monitoring of the Town of Fuquay-Varina system (PWSID NC0392055) found PFOA and PFOS at both entry points — as high as 11 ppt each in November 2023, still 5.9 to 7.8 ppt by February 2024 — above EPA's 4.0 ppt limit. This is monitoring data, not a violation. Carbon certified for PFAS handles it, in the same all-in-one system built for this market.

Does Fuquay-Varina, NC water have PFAS?

Yes — EPA's UCMR5 monitoring of the Town of Fuquay-Varina system (PWSID NC0392055) detected PFOA and PFOS at both of the town's tested entry points. On November 9, 2023, entry point EP001 tested at PFOA 11 ppt and PFOS 11 ppt, while entry point EP003 tested at PFOA 10 ppt and PFOS 9.3 ppt. By February 15, 2024, both points came in lower but still detectable: PFOA between 5.9 and 6.8 ppt, PFOS between 6.6 and 7.8 ppt.

UCMR5 is EPA's nationwide program for monitoring unregulated contaminants across thousands of water systems. It builds an occurrence dataset, not a compliance record — these are real, verified readings reported exactly as EPA published them.

How do Fuquay-Varina's PFAS numbers compare to EPA's limit?

EPA's April 2024 PFAS rule set enforceable Maximum Contaminant Levels of 4.0 ppt each for PFOA and PFOS. Every reading at both Fuquay-Varina entry points, across both sampling rounds, came in above that number — 11 and 10 ppt for PFOA in 2023, still 5.9 to 6.8 ppt in early 2024.

That comparison is worth stating plainly, but it isn't a violation. UCMR5 monitoring data isn't the compliance testing utilities are held to under the rule. EPA's 2024 rule set a compliance date of 2029 for those limits, and in May 2026 EPA proposed keeping the 4.0 ppt limits while giving systems the option to request two additional years, to 2031.

Why does Fuquay-Varina have two different sets of PFAS readings for the same day?

Because the town draws from more than one source, tested at two separate entry points into its system. Fuquay-Varina purchases water from three different suppliers — the City of Raleigh, Harnett County, and Johnston County — so what reaches a given address depends on which supply feeds that part of town. EP001 and EP003 aren't duplicate readings of the same water; they're two real entry points that can carry a different blend.

That's exactly why an address-level test matters more here than in a town served by a single plant. A number from one entry point doesn't guarantee what's coming out of a tap fed primarily by the other.

What other PFAS compounds were detected?

Alongside PFOA and PFOS, the same UCMR5 rounds found PFHxA up to 19 ppt, PFPeA up to 21 ppt, PFBS up to 15 ppt, PFBA up to 13 ppt, PFHpA up to 7.0 ppt, and PFHxS up to 4.4 ppt. None of these six compounds carries an individual EPA Maximum Contaminant Level. The November 2023 round at EP001 also detected 6:2 FTS at 5.9 ppt.

Does boiling water remove PFAS from Fuquay-Varina tap water?

No — boiling does not remove PFAS, and it can concentrate it. Water leaves the pot as steam; the PFAS dissolved in it stays behind, so a smaller volume ends up carrying the same amount. Boiling is a fix for bacteria, not for a compound like this one.

What actually removes PFAS from Fuquay-Varina water?

Carbon certified for PFAS, or reverse osmosis. PFOA and PFOS need activated carbon certified to NSF/ANSI 53 or P473, or reverse osmosis certified to NSF/ANSI 58 — a basic pitcher filter or uncertified carbon isn't tested against either standard.

A water softener alone does nothing here. It's ion exchange for calcium and magnesium, with no mechanism for pulling PFAS out of water. An all-in-one whole-home system pairs a PFAS-rated carbon stage with softening resin, so the carbon side handles PFAS while the softening side protects your water heater, dishwasher, and plumbing from mineral buildup — one install, both problems solved.

FAQ

Did Fuquay-Varina violate a water quality law with these PFAS numbers? No. EPA's UCMR5 program collects nationwide occurrence data — it isn't compliance testing, so there's no violation to report. Every reading at both entry points sits above the 4.0 ppt MCL that now applies to PFOA and PFOS, which is worth knowing, but that's a comparison against a limit, not a legal breach.

I just moved to Fuquay-Varina and heard the town buys water from three different places — does that mean my water is worse than my neighbor's? Not necessarily worse, just potentially different. Fuquay-Varina purchases from Raleigh, Harnett County, and Johnston County, and the two tested entry points showed different PFAS readings on the same sampling day. A free water analysis at your specific address is the only way to know which supply reaches your tap.

I've been boiling my water because I'm worried about PFAS in Fuquay-Varina — is that helping? Unfortunately not — it works against you. Boiling drives off water, not PFAS, so the pot ends up holding the same amount in less liquid. What you want instead is carbon certified to NSF/ANSI 53 or P473, or reverse osmosis certified to NSF/ANSI 58, both of which remove it properly.

Will a water softener take care of the PFAS in Fuquay-Varina's water? No. A softener is ion exchange built specifically for calcium and magnesium — it has no mechanism for PFAS. Removing PFAS requires a carbon stage rated for it or reverse osmosis; an all-in-one system pairs that carbon stage with softening resin so both are handled in one unit.

Why did Fuquay-Varina's PFAS levels drop between November 2023 and February 2024? The dataset doesn't explain the cause, and round-to-round change is normal in occurrence monitoring — it can reflect source blending, seasonal flow, or other factors EPA's dataset doesn't capture. What it shows is that levels stayed detectable at both points across both rounds, which is why a carbon stage rated for PFAS removal is a more reliable answer than counting on a lower reading next time.

Is it worth testing my own Fuquay-Varina address if EPA already tested the system? Yes — EPA's UCMR5 sampling reflects two entry points into the system, not necessarily what comes out of your specific tap after your home's own plumbing and whichever supply feeds your part of town. A free water analysis gives you a number tied to your actual address, plus a system sized to it.
