Clay Water Hardness & Quality Report (2026)

Clay Uniform Water Districts (Public Water Supply ID# NY3304344), located at 4401 State Route 31, Clay, New York 13041, serves the Town of Clay in Onondaga County — a suburb north of Syracuse in Central New York. The utility draws its entire supply from Lake Ontario, treating approximately 18.19 million gallons per day from an intake near the City of Oswego. Water is processed at the district's treatment facilities using conventional filtration and chlorination before distribution to residential and commercial customers throughout the uniform water districts.

The primary watershed is Lake Ontario within the Great Lakes Basin, fed by rivers including the Niagara and Oswego draining vast areas of upstate New York and Ontario, Canada. Underlying geology features Paleozoic carbonate rocks — Silurian dolomites, Ordovician limestones, and associated shales — with glacial till and moraines overlaying these formations. Watershed drainage through this limestone and dolomite terrain naturally dissolves calcium and magnesium ions into the lake, imparting a hard character to the supply with minimal natural softening due to the basin's carbonate-rich lithology.

Hard water promotes scale buildup in pipes, heaters, and fixtures, shortening the lifespan of water heaters, dishwashers, washing machines, and coffee makers. Soap lathering is reduced, leaving residues on skin, hair, and laundry. Regular descaling of appliances and flushing hot water systems is advised; a water softener is recommended to mitigate scaling and extend plumbing life. The 2024 Annual Drinking Water Quality Report confirms lead compliance (90% of taps ≤2.5 µg/L, action level 15 µg/L) and copper rule compliance; chlorine residual averages 0.69 mg/L; bromodichloromethane detected above health guidelines is addressed via filtration including activated carbon.
