Perfluorooctanesulfonic acid
21.8ng/L
Each block = 4.0 ng/L federal MCL (2024)
Short answer: Three PFAS, PFHxS, PFOA and PFOS, are above their federal limits (2024 limits that water systems have until at least 2029 to meet); 4 more are detected with no federal limit, and everything else measured is within its reference or not detected. Fayetteville Public Works Commission serves 226,441 residents.

FAYETTEVILLE PUBLIC WORKS COMM (EPA PWSID NC0326010) delivers surface water to 226,441 residents. This report reflects 29 individual PFAS result(s) from the source UCMR5 observations and the latest Lead & Copper Rule 90th-percentile result. Water hardness and disinfectant type are pending the utility's own annual report.
0health-based violations in the last 10 years
From EPA SDWIS. A clean violation history means no enforcement action was recorded; it does not cover contaminants without a limit.
No result is not a pass. Your utility's annual water quality report may list them, and a certified lab test covers your own tap.
Plumbing inside a home can add lead that the system record can't show. A tap test tells you what reaches your glass.
PFOS 21.8 ng/L, above the 4 ng/L limit (+8 more PFAS detected)
247 galvanized lines to replace
Screening tells you if something is worth a closer look; a lab result is the number you can act on.

Lead, read as one of three ranges: 0–4, 5–15 or 15+ ppb
What it can't tell you: It shows a lead range, not an exact level, and tests nothing else unless you pay extra for the optional lab test.
Lab-certified results
ETR Laboratories
50+ substances, including lead, copper, arsenic, nitrate, hardness and coliform bacteria
What it can't tell you: It does not test PFAS, and not every result on the panel falls under the lab's accredited scope.

PurityMap does not give a safe/unsafe verdict; it shows what the public records measured. For Fayetteville, PFOS 21.8 ng/L (limit 4 ng/L), PFOA 11 ng/L (limit 4 ng/L) and PFHxS 19.1 ng/L (limit 10 ng/L) were measured above their limits in EPA's 2024 testing. FAYETTEVILLE PUBLIC WORKS COMM (PWSID NC0326010) has a Purity Score of 57/100 (confidence: moderate), assessed at the water-system level and computed only from contaminants that were measured. Water can change in your own pipes, so a certified test is the only way to know what comes out of your tap.
FAYETTEVILLE PUBLIC WORKS COMM (PWS ID NC0326010) is the public water system on record for Fayetteville, North Carolina, serving about 226,441 people. Confirm the utility on your water bill before acting on a specific finding.
Surface water (primary source of record in EPA SDWIS).
Yes. In EPA's UCMR 5 testing (2023-10-17 to 2024-07-10), PFOS was measured at 21.8 ng/L against a 4 ng/L federal limit, PFOA was measured at 11 ng/L against a 4 ng/L federal limit and PFHxS was measured at 19.1 ng/L against a 10 ng/L federal limit. PFBS (12.1 ng/L, below the 2,000 ng/L EPA health advisory) and PFHxA (18.2 ng/L, below the 400,000 ng/L state limit) were also detected. 6:2 FTS (7.7 ng/L), PFBA (11.4 ng/L), PFHpA (7 ng/L) and PFPeA (21.5 ng/L) were also detected; they have no federal or state limit. Reverse osmosis and filters certified to NSF/ANSI 53 for PFOA/PFOS reduce them at the tap.
Lead is not in Fayetteville's current published record. Lead usually enters from a building's own pipes and fixtures, so a certified home test is the way to know yours.
PurityMap's current record for Fayetteville holds 31 findings: 3 above a reference, 2 detected within the reference, 4 detected with no limit and 22 not detected. Each finding links to its dated public record; a parameter that was never monitored is shown as pending, not as a pass.
