Ashe County – West Jefferson and Jefferson – serves about 27,000 residents in the high mountains along the Virginia and Tennessee borders. Water comes from the headwaters of the New River, one of the oldest rivers in the world. The New River flows north through Virginia and West Virginia, and Ashe County sits at its origin, giving the county first access to its clean mountain water.
Ashe County benefits from headwater-quality source water with no upstream contamination sources. UCMR5 data shows no PFAS detections. According to NC DEQ's 2024 data, systems met all standards. The county's remote mountain setting provides natural watershed protection through forest cover and low population density.
Ashe County's headwater position on the New River gives it source water that no downstream community can match.
