From the mountains to the sea, a state with a lot of water stories. North Carolina.
In the mountains, Asheville went 53 days without drinkable tap water after Hurricane Helene. On the coast, PFAS flowed into the Cape Fear River for decades. And Charlotte earned the state's only F for ozone. Here is the picture, based on public data.

From the City of Asheville and U.S. EPA, Cape Fear Public Utility Authority, the American Lung Association and local reporting
- Residents affectedMore than 100,000

- Boil water notice liftedNovember 18, 2024
- Samples tested before liftingMore than 1,000
Flooding destroyed water infrastructure and filled reservoirs with sediment, so even once water flowed, it wasn't safe to drink for weeks.
Asheville recommends running cold water for 30 seconds to 2 minutes before collecting water to drink, every day.
Wilmington's utility built eight deep-bed granular activated carbon filters, and says PFAS has not been detected in its treated water since October 2022.
The Charlotte metro ranks 69th worst for ozone and fails for year-round particles, 45th worst (ALA 2026). About 270,000 North Carolina children live with unhealthy air.
Where you live changes what matters
The mountains think about post-disaster water, the coast about river pollution, the cities about smog.
CharlotteCharlotte, Matthews, Concord
The state’s only F county for ozone, and over the limit for year-round particles. Summer smog is the main air concern.
The TriangleRaleigh, Cary, Durham, Chapel Hill
Known for spring pine pollen that coats everything yellow. Ozone and particles are better than Charlotte’s.
Cape Fear · CoastWilmington, downstream of Fayetteville, Brunswick
Once the center of the PFAS story; Wilmington’s Sweeney plant now treats it with large carbon filters. Hurricane prep matters here too.

The water system is restored after Helene, but homes with older plumbing are still advised to flush the cold tap first each day.

Typical patterns only; they vary year to year. As Helene showed, storms can do serious damage far inland in the mountains.
It meets today's standard. Is that enough?
In North Carolina, PFAS isn't just a Cape Fear River story. Wilmington's utility now treats PFAS with large carbon filters, but other systems across the state are measuring levels above the new federal limit. Because the federal limit doesn't apply until 2029, those readings aren't violations yet.
Even in the Triangle, Raleigh's tap water has measured PFOS slightly above the federal limit. Utility treatment upgrades take years, and as Wilmington showed, large systems are expensive. Activated carbon and reverse osmosis (RO) are the leading technologies for reducing PFAS, so an RO purifier at the one tap you drink from lets you start managing your water now. Check each model's certifications on its product page.
Homes with plumbing from before 1988, like those Asheville flagged, are advised to flush the cold tap daily, and during a post-hurricane boil water notice you should boil your purifier's water too or use bottled water. Rental customers get the post-notice filter check covered with regular service. For the air side: HEPA filters capture particles like pollen and fine dust, but ozone is a gas and HEPA filters don't remove it.
