Albany Water Hardness & Quality Report (2026)

Albany, New York — the state capital — draws its municipal water supply from the City of Albany Water Department, sourcing from a protected watershed system in Albany County: the Alcove Reservoir (on Hannacroix Creek — a Hudson River tributary) and the Basic Creek Reservoir in the Helderberg Escarpment region, supplemented by the Vly Creek Reservoir system in Albany County. The Helderberg Plateau watershed overlooks the Hudson Valley and is underlain by Devonian carbonate formations. Water hardness measures 110 mg/L — classified as moderately hard.

Albany's moderate hardness reflects the geology of the Helderberg Escarpment watershed in Albany County. The Alcove and Basic Creek reservoir catchments drain the Helderberg Plateau — the prominent limestone escarpment west of Albany underlain by Devonian Onondaga Limestone (famous for its rich fossil fauna), Devonian Helderberg Group formations (Coeymans Limestone, Kalkberg Limestone, New Scotland Limestone, and Becraft Limestone), and the Devonian Hamilton Group (calcareous shale and limestone). These Devonian carbonate and calcareous shale formations dissolve moderate calcium into Hannacroix Creek and tributary drainage, producing moderately hard supply in Albany's reservoir system.

At 110 mg/L, Albany residents encounter moderate scale accumulation. Faucet aerators and showerheads develop deposits after several months — monthly cleaning with citric acid solution is practical maintenance. Dishwashers produce cleaner glassware with rinse-aid. City of Albany Water Department consistently delivers water meeting all NYSDOH and EPA Safe Drinking Water Act requirements.
