New Albany Water Hardness & Quality Report (2026)

Indiana American Water - Greater Jeffersonville Area serves New Albany, Indiana, alongside Jeffersonville and Clarksville in Clark County. The utility draws from 17 groundwater wells as its sole water source, supplying an average of 15.4 million gallons per day. All supply is groundwater-based — there are no surface water treatment plants in this service area. Water is drawn from underground aquifers and treated at dedicated facilities before distribution, with chlorine disinfection applied throughout the distribution system to maintain safety and quality.

Recharge for this groundwater supply occurs through the broader Ohio River Valley drainage basin, where permeable soils and karst features overlie Mississippian limestone formations. Key formations include the Borden Group limestones and dolomites, as well as Valmeyeran Series rocks — notably the Ste. Genevieve and St. Louis Limestones — prevalent across southern Indiana. These karstic carbonate layers dissolve over geological time, leaching substantial calcium and magnesium ions into the aquifers, creating a characteristically hard and mineral-rich groundwater profile typical of the region.

At 182 mg/L, New Albany's water is very hard, causing significant scale buildup in pipes, water heaters, dishwashers, and washing machines, reducing efficiency and lifespan. Faucets and fixtures develop stubborn mineral deposits, and soap lathering is diminished. Regular deliming of appliances and installation of scale inhibitors is advised; a water softener is strongly recommended to protect plumbing and extend appliance life. The 2024 Consumer Confidence Report shows pH averaging 7.47 with hardness ranging 158–209 ppm; the utility confirms compliance with lead regulations and no PFAS exceedances.
