Fayetteville Water Hardness & Quality Report (2026)

Fayetteville, North Carolina receives its municipal water from PWC (Public Works Commission of the City of Fayetteville), sourcing raw water from Lake Purvis — a reservoir created on Bones Creek — and supplemental intakes on the Cape Fear River in Cumberland County. Raw water is treated at the Hoffer Water Treatment Plant, which serves the city and surrounding Cape Fear area communities. The Cape Fear River basin's generally sandy, low-calcium coastal plain geology produces relatively soft supply throughout the year. Water hardness in Fayetteville measures 69.5 mg/L — classified as moderately soft.

Fayetteville's moderate softness is rooted in the geology of the Cape Fear River watershed and the Carolina Sandhills. The Cape Fear basin at this latitude traverses the Cretaceous Atlantic Coastal Plain — a wide belt of unconsolidated quartz sand, kaolinite clay, and occasional marl deposited in ancient shallow sea environments. These sediments, while calcium-poor overall, overlie weathered Triassic rift basin sediments and Paleozoic crystalline basement to the northwest, contributing modest but limited calcium to surface runoff. The dominance of silica-rich sandy terrain keeps overall mineral dissolution low.

With hardness at 69.5 mg/L, Fayetteville residents experience minimal scale accumulation in everyday household use. Faucet aerators and showerheads can go several months between cleanings, and kettles accumulate only a minor mineral film over time. Soap and shampoo lather freely with standard amounts, and dishwashers tend to produce clean, spot-free results without heavy reliance on rinse-aid. Hot water systems experience minimal long-term scale build-up. As one of the larger cities in North Carolina, Fayetteville's PWC consistently delivers water that meets or exceeds all EPA Safe Drinking Water Act requirements.
