Carteret County, North Carolina: drinking water report. Carteret County on the central North Carolina coast has about 70,000 residents in communities…
Carteret County on the central North Carolina coast has about 70,000 residents in communities including Morehead City and Beaufort. The county relies on groundwater from the Castle Hayne and deeper confined aquifers, supplemented by surface water from Bogue Sound watershed. Marine Corps Air Station Cherry Point in neighboring Craven County sits directly upgradient from some of the county's water resources.
Saltwater intrusion is a persistent threat to Carteret County's shallow wells. According to NC DEQ's 2024 coastal groundwater monitoring report, chloride concentrations have been rising in production wells on Bogue Banks and along the Intracoastal Waterway. Heavy pumping during tourist season – the county's population swells significantly in summer – accelerates the intrusion.
PFAS from MCAS Cherry Point's operations has been detected in groundwater that extends into northern Carteret County. A 2024 NC DEQ investigation documented PFAS at 15 ppt in monitoring wells along the county's northern border. The combination of military contamination and saltwater intrusion creates a squeeze on available clean groundwater.
Carteret County's coastal location means water quality shifts with the seasons and with pumping demand. If your water tastes different in summer – saltier or harder – that reflects real changes in aquifer chemistry driven by tourist-season demand.
