The Charlotte metro spans 2.7 million people across a region that includes some of the most closely watched water contamination in the United States. Charlotte itself draws from Mountain Island Lake and Lake Norman, managed by Charlotte Water. Raleigh pulls from Falls Lake and the Neuse River system. Durham runs from Lake Michie and Little River Reservoir. Greensboro taps multiple reservoirs in the Piedmont region. Each city operates independently, with different source waters and different contaminant profiles.
North Carolina's water quality conversation, though, has been dominated by a single word for nearly a decade: GenX.
The Chemours Company's Fayetteville Works facility, located on the Cape Fear River downstream from the Charlotte metro, has been discharging GenX (a PFAS replacement compound) into the river since at least the 1980s – decades before anyone was testing for it. While the Cape Fear River contamination most directly affects Wilmington and downstream communities, the case elevated PFAS awareness across the entire state.
Within the Charlotte metro, UCMR5 testing has confirmed PFAS detections in multiple water systems. Charlotte Water's Mountain Island Lake supply has shown lower PFAS levels than communities drawing from the Cape Fear watershed, but detections are present. The Raleigh-Durham area, which draws from different basins, has its own contamination concerns linked to military sites and industrial activity.
North Carolina set a health goal of 140 ppt for GenX specifically – a compound-specific standard that few other states have addressed. According to NC DEQ data, 18 community water systems statewide have reported detectable GenX levels, with the highest concentrations in southeastern North Carolina.
North Carolina's role in the national PFAS story is outsized. The GenX contamination in the Cape Fear basin drew Congressional attention and prompted some of the earliest state-level PFAS regulations in the country. The Charlotte metro benefits from being upstream of the worst contamination, but the regulatory scrutiny has pushed all North Carolina utilities to test and report more aggressively than many peer states.
Within the metro, Charlotte Water's reservoir-based supply generally tests cleaner than systems relying on river intakes. Greensboro and Durham occupy a middle ground. The variation across this 2.7 million person metro is wide enough that metro-level averages are not useful.

Which city you're in matters more here than in most metros. Charlotte, Raleigh, Durham, and Greensboro operate entirely separate water systems with different source waters.
Check your water to see data for your specific system. If you're in a community drawing from the Cape Fear watershed or near military installations like Fort Liberty (formerly Fort Bragg, south of the metro), PFAS exposure could be significant. Our water filter guide covers filters tested against GenX and other replacement PFAS compounds.
