New Albany Water Hardness & Quality Report (2026)

New Albany, Indiana, the Floyd County seat — a major south Indiana Ohio River city directly across from Louisville, Kentucky (New Albany is one of the three major Indiana cities in the Louisville–Jefferson County metropolitan area, along with Jeffersonville and Clarksville), a historic community with significant Victorian and antebellum architecture (New Albany was the largest city in Indiana in the 1850s — primarily due to its Ohio River steamboat and boat-building industry), home of Floyd Memorial Hospital and a growing Louisville-facing suburban and urban community, and a diverse Floyd County community — draws its municipal water supply from the Ohio River via the New Albany Water Works. Water hardness in New Albany measures 120.5 mg/L — classified as moderately hard.

New Albany's moderate hardness reflects the Ohio River watershed's calcareous geology and New Albany Water Works treatment. The Ohio River at New Albany–Floyd County carries runoff from: the Mississippian Salem, Ste. Genevieve, and Warsaw Limestone (highly calcareous limestone of the south Indiana Carboniferous Platform); the Pennsylvanian calcareous limestone and dolomite; and the Ohio River alluvial deposits. New Albany Water Works applies coagulation and filtration treatment, producing the moderate 120.5 mg/L.

At 120.5 mg/L, New Albany residents encounter moderate scale accumulation. Monthly cleaning with citric acid solution is recommended. New Albany Water Works consistently delivers water meeting all Indiana DEM and EPA Safe Drinking Water Act requirements.
