Per- and polyfluoroalkyl substances — PFAS, commonly called \"forever chemicals\" — have become one of the most significant water quality concerns in North Carolina and across the United States. North Carolina sits at the center of national PFAS awareness due to documented industrial contamination, and the issue extends beyond the most-publicized southeastern NC cases into communities throughout the state, including the greater Raleigh area.

What Are PFAS?

PFAS is a family of thousands of synthetic chemical compounds used in industrial and consumer products since the 1940s. They appear in non-stick cookware, water-resistant fabrics, food packaging, firefighting foam (AFFF), and numerous industrial applications. Their defining characteristic — extraordinary chemical stability — is both what makes them useful and what makes them a problem. They do not break down in the environment or in the human body, accumulating over time with continued exposure.

How PFAS Get Into North Carolina Water

Industrial Discharge

North Carolina has documented PFAS contamination linked to industrial facilities discharging into surface water. The Cape Fear River system's contamination from GenX chemicals released by a fluorochemical manufacturer brought national attention to NC's PFAS problem and led to significant state-level regulatory action.

Military Installations and Airports

Firefighting foam containing PFAS (AFFF) has been used for decades at military bases and airports. Groundwater contamination from these sites has affected private wells and, in some cases, municipal water supplies in surrounding communities throughout NC.

Widespread Product Use

Beyond point-source contamination, PFAS have dispersed widely through product use, landfills, and biosolids application on agricultural land. They've been detected in water supplies across the country where no obvious industrial source exists.

Health Concerns Associated with PFAS

Research has associated long-term PFAS exposure with a range of health concerns. The EPA finalized the first-ever national maximum contaminant levels (MCLs) for several PFAS compounds in 2024 — a recognition of their health significance. Because PFAS have no taste or odor, the only way to know if they're present in your water is testing.

What About PFAS in Raleigh\'s Water Supply?

The City of Raleigh and other Wake County utilities have been conducting PFAS monitoring. Recent results have generally shown concentrations below the EPA's new limits, but monitoring is ongoing and standards continue to evolve. For private well users in the greater Raleigh area, there is no mandatory PFAS monitoring — testing must be initiated by the homeowner.

What Pittsboro Residents Should Know

Pittsboro's municipal water supply — drawn from the Haw River — has been a focus of elevated PFAS concern due to upstream industrial discharge into the Cape Fear system. The Town of Pittsboro has taken treatment steps, but many residents have installed reverse osmosis systems as a proactive precaution. If you're on Pittsboro municipal water, RO filtration at the kitchen tap is a well-reasoned protective measure.

How to Remove PFAS from Your Water

Reverse Osmosis --- The Most Effective Point-of-Use Solution

NSF/ANSI Standard 58-certified reverse osmosis systems consistently demonstrate high reduction rates for a broad range of PFAS compounds. An under-sink RO at the kitchen tap is the most practical and cost-effective solution for drinking and cooking water protection. Look specifically for systems with an NSF 58 PFAS claim.

Activated Carbon Filtration --- Whole-Home Protection

Granular activated carbon (GAC) filtration with adequate media volume and contact time provides meaningful PFAS reduction across many compound types. Whole-home carbon systems installed at the point of entry provide broader protection — including for shower and bath water — though RO remains the gold standard for drinking water specifically.

What Doesn\'t Work for PFAS

  • Standard sediment filters --- remove particles only, no effect on

dissolved PFAS

  • Water softeners --- address hardness ions, no effect on PFAS
  • UV disinfection --- kills pathogens, no effect on PFAS
  • Basic pitcher filters --- limited and inconsistent PFAS removal

Should You Test for PFAS?

If you are on a private well, near an industrial site or military installation, or simply want to know your exposure level, PFAS testing is available through state-certified laboratories. Standard water tests do not include PFAS analysis by default — you must request it specifically.
