Pleasure Ridge Park Water Hardness & Quality Report (2026)

Pleasure Ridge Park, Kentucky, is an unincorporated community in Jefferson County served by Louisville Water Company, one of the oldest and largest municipally owned water utilities in the country, founded in 1860. Louisville Water draws its supply directly from the Ohio River, maintaining intake facilities along the river corridor. Water undergoes treatment at the Crescent Hill Water Treatment Plant — one of two main treatment facilities — where advanced sedimentation, filtration, and disinfection prepares Ohio River water for distribution throughout the Louisville metro area, including Pleasure Ridge Park in the southwestern suburbs.

The hard 165.5 mg/L hardness reflects the Ohio River's deep exposure to Devonian carbonate geology throughout its drainage basin. Near Louisville, the river flows directly over the Falls of the Ohio — an exposed Devonian coral reef complex containing extraordinary concentrations of calcite-rich fossil limestone, recognized as one of the best-preserved Devonian reef systems in North America. Upstream tributaries across Indiana, Ohio, and Kentucky drain extensive karst limestone plains, loading the Ohio River with dissolved calcium and magnesium bicarbonates throughout its journey.

At 165.5 mg/L, Pleasure Ridge Park's water is solidly in the hard category, and mineral-related scaling is a consistent reality for residents. Kettles develop white crust within weeks of regular use, dishwashers leave cloudy spots on glasses, and water heaters gradually lose efficiency as scale insulates heating elements. Regular descaling every two to three months is recommended for small appliances, and a water softener or ion-exchange system offers meaningful protection for washing machines and water heaters. Wiping down bathroom tile and glass shower doors daily significantly reduces the buildup of unsightly limescale deposits in this hardness range.
