Quick Answer
Is PFAS in drinking water a real concern in North Carolina?
Yes — North Carolina has one of the most significant industrial PFAS contamination cases in the nation. Chemours' Fayetteville Works plant on the Cape Fear River has discharged PFAS — including the novel compound HFPO-DA (GenX) — into the river for decades, contaminating the drinking water supply for hundreds of thousands of downstream residents including Wilmington, NC.
Where does PFAS come from in North Carolina?
Chemours' Fayetteville Works facility (formerly DuPont) in Bladen County is the dominant PFAS source in North Carolina. The plant manufactures fluoropolymers and has discharged PFAS compounds — including novel 'replacement' PFAS like GenX — into the Cape Fear River through direct discharge and air deposition. Communities drawing drinking water from the Cape Fear River downstream from the plant, including Wilmington (population ~120,000) and other Brunswick and New Hanover County communities, have been exposed to elevated PFAS levels for decades.
What should North Carolina residents know?
Wilmington area residents and all communities drawing water from the Lower Cape Fear River should review their utility's PFAS data. The Cape Fear River Basin extends from the Piedmont to the coast, and multiple water utilities draw from this source. NC DEQ has implemented significant regulatory actions against Chemours and is pursuing further restrictions. North Carolina also has military installations including Seymour Johnson AFB that contribute additional PFAS loading.
Key Facts
| EPA MCL (PFOA/PFOS) | 4 ppt — effective April 2024 |
| EPA MCL for HFPO-DA (GenX) | 10 ppt — specifically relevant to NC Cape Fear River contamination |
| MCLG | Zero |
| Primary contamination source | Chemours Fayetteville Works plant (Bladen County) — Cape Fear River PFAS discharge including novel GenX compound |
| Communities affected | Wilmington, Brunswick County, New Hanover County — Cape Fear River water users |
| Historical significance | GenX discovery at Wilmington in 2017 accelerated EPA PFAS MCL rulemaking |
| State regulator | NC Division of Water Resources — active enforcement against Chemours |
| Health effects | Cancer risk, thyroid disruption, immune effects; GenX-specific health data still emerging |
| Effective treatment | GAC or RO — Wilmington utilities have installed treatment; RO for households |
Why PFAS Matters in North Carolina
North Carolina's Cape Fear River PFAS contamination case is unique in several ways: it involves novel 'next-generation' PFAS compounds like GenX (HFPO-DA) that were used as replacements for PFOS and PFOA — compounds that were supposed to be safer but turned out to have similar toxicity concerns. The discovery of GenX in Wilmington's water in 2017 by UNCW researchers shocked the scientific community and the public. Chemours' facility had been discharging these novel PFAS compounds without any regulatory limit because they were unregulated replacements. The EPA has since set an MCL of 10 ppt for HFPO-DA as part of the 2024 PFAS rule. North Carolina has pursued aggressive legal and regulatory action against Chemours and DuPont.
Historical Context
UNCW researcher Detlef Knappe's discovery of GenX (HFPO-DA) in Wilmington's tap water in 2017 is considered a landmark moment in PFAS science. The findings demonstrated that 'replacement' PFAS compounds were being used in manufacturing and discharged without any regulatory oversight — a loophole that accelerated EPA action on a comprehensive PFAS MCL covering multiple compounds.
North Carolina PFAS Regulation
North Carolina DEQ has focused PFAS regulatory efforts on the Chemours/DuPont Fayetteville Works facility, which discharges PFAS (including GenX/HFPO-DA) into the Cape Fear River — the drinking water source for Wilmington and surrounding communities. North Carolina enacted the PFAS notification rule in 2022 requiring utilities to notify customers of detections. The state is developing its own MCLs and has been at the forefront of GenX regulation nationally.

What Are PFAS (“Forever Chemicals”)?
PFAS are a family of over 12,000 synthetic chemicals used in non-stick cookware, stain-resistant fabrics, food packaging, and AFFF firefighting foam. Their carbon-fluorine bonds do not break down in the environment or the body — hence the name “forever chemicals.” AFFF used at military bases is the single largest source of PFAS in U.S. drinking water.

Wilmington, Brunswick County, and New Hanover County residents drawing water from the Cape Fear River face the most direct risk. Communities in Bladen County near the Fayetteville Works plant face the highest concentrations. Seymour Johnson AFB area residents in Wayne County face additional military-source PFAS exposure.

Private well owners near military or industrial sites
Pregnant residents and families with young children
Residents in communities with documented PFAS detections
Anyone who has consumed water above 4 ppt for an extended period
Residents near airports, fire training areas, or industrial manufacturers
How to Check Your Situation in North Carolina
- 1
Identify your water utility using the ZIP lookup below or by browsing the North Carolina utility directory on this site.
- 2
Review your utility's Consumer Confidence Report (CCR) — it must report PFAS monitoring results under UCMR5 and the new MCL.
- 3
Check the EPA's ECHO database for your utility's monitoring history. Look for PFAS, PFOA, PFOS, and related compound results.
- 4
Contact your utility directly and ask for their most recent PFAS test results and whether they are implementing treatment under the 2024 MCL.
- 5
If you use a private well near a military base, airport, or industrial facility, order a PFAS panel test from a state-certified laboratory. Tests typically cost $150–$400.
- 6
If PFAS is detected above 4 ppt in your source water, install a certified NSF/ANSI 58 reverse osmosis system or an NSF/ANSI 53-certified activated carbon filter rated for PFAS removal.
How to Remove PFAS from Tap Water
Reverse Osmosis (Best)
90–99% removal — NSF/ANSI 58 certified systems only
Certified Activated Carbon
Effective with NSF/ANSI 53 or 58 certification — verify before buying
Boiling concentrates PFAS. Standard pitcher filters and water softeners do not remove PFAS. Always verify NSF certification before purchasing.
Take Action Now
Look up your North Carolina utility's PFAS monitoring history on the PFAS Watchlist below.
If your utility has detected PFAS above 4 ppt, install an NSF/ANSI 58-certified reverse osmosis system at your drinking tap.
Private well owners near military or industrial sites should order a PFAS panel test ($150–$400 at a state-certified lab).
Request your utility's most recent Consumer Confidence Report — PFAS results must be disclosed under the new 2024 MCL.
