Wilson Water Hardness & Quality Report (2026)

The City of Wilson utility (WILSON, CITY OF) serves approximately 50,001 residents in Wilson County, North Carolina. Water is sourced from surface water treated at the Wiggins Mill Water Treatment Plant (mailing address: PO Box 10, Wiggins Mill WTP, Wilson, NC 27894; phone: 252-399-2376). The plant employs conventional filtration and chlorine disinfection to process raw surface water before distribution across the service area.

The supply originates from surface waters in the coastal plain watersheds near Wilson, likely tributaries of the Neuse River Basin. Underlying Cretaceous and Tertiary sedimentary formations — sands and clays from the Black Creek and Peedee groups — influence water chemistry by contributing moderate dissolved ions as water moves through the low-relief terrain. The minimal presence of limestone prevents extreme hardness; instead, the sandy aquifers and riverine inputs produce a balanced, moderately mineralised profile shaped by seasonal precipitation patterns.

In a moderately hard supply, scale buildup can develop in water heaters, dishwashers, and washing machines, reducing efficiency and leaving visible deposits on plumbing fixtures. Soap usage increases and glassware may show spotting. Regular vinegar descaling, drain screens, and a water softener — particularly where the supply leans harder — are recommended to extend appliance life and improve laundry results. The utility reports no EPA violations, with all contaminants meeting health guidelines and a quality score of 100/100 in recent assessments. Treatment relies on conventional filtration and chlorination; independent data notes potential concerns with TTHMs and chromium-6 above some health guidelines, though within EPA MCLs. No specific PFAS issues appear in available reports.
