Jamestown Water Hardness & Quality Report (2026)

Jamestown Board of Public Utilities (BPU) serves approximately 47,425 residents in Jamestown, Chautauqua County, New York. The utility draws drinking water exclusively from 12 artesian wells — eight in the Cassadaga well field tapping the Cassadaga aquifer, and four in the Poland Center well field tapping the Conewango aquifer. There are no surface water treatment plants; water is treated at wellhead facilities using disinfection and other processes before entering the distribution system. The utility is located at 92 Steele St, Jamestown, NY 14701, reachable at 716-661-1606.

The Cassadaga and Conewango aquifers sit within western New York's glacial drift overlying Devonian-age bedrock of the Appalachian Basin, including shales, sandstones, and carbonate-rich limestones and dolomite. As groundwater recharges through these formations, it dissolves calcium and magnesium ions from the limestone and dolomite layers, producing a hard supply. Source water assessments indicate medium-high susceptibility to microbials, viruses, and nitrates from pastureland and wastewater influences, alongside medium risk from industrial solvents.

At 171.2 mg/L, this hard water drives significant scale buildup in pipes, water heaters, dishwashers, and washing machines, reducing efficiency and shortening appliance lifespan. Affected appliances may require more frequent descaling or early replacement. Regular descaling with vinegar and selecting scale-resistant appliance models is advisable; a water softener is strongly recommended to mitigate these effects and improve soap lathering. The 2025 Annual Water Quality Report confirms compliance with EPA standards for lead and copper; treatment includes disinfection, regular monitoring, and corrosion control.
