Pleasure Ridge Park Water Hardness & Quality Report (2026)

Kentucky American Water (Kentucky-American Water Company) serves Pleasure Ridge Park, an unincorporated community in southwest Jefferson County, Kentucky, as part of the Louisville metropolitan area. The utility draws water primarily from the Ohio River at the Louisville Water Treatment Plant, supplemented by reservoirs including Harrods Creek and Floyds Fork. Treatment occurs at major plants including the River Road and Pond Creek facilities, distributing to over 300,000 customers across Jefferson County and surrounding areas.

The Ohio River watershed spans the unglaciated Appalachian Plateau, featuring karst topography with Mississippian-age limestone and dolomite bedrock. Formations including the Ste. Genevieve and Bethel formations promote high mineral leaching into rivers and aquifers. Groundwater components also tap the karstic Pennyroyal aquifer system — Paleozoic limestone-based — which concentrates calcium and magnesium through prolonged contact with fractured carbonates, with acidic rainfall accelerating dissolution rates across the region.

At hard levels, mineral scaling affects water heaters, dishwashers, and washing machines most, reducing efficiency and lifespan by 30–50%. Soap lathering diminishes, increasing detergent use, while fixtures develop stubborn deposits. Regular vinegar descaling and annual appliance flushes help mitigate buildup. A water softener is recommended for households to prevent these issues and extend equipment durability. Kentucky American Water maintains pH between 7.0–8.5 for corrosion control, with full compliance on lead and copper under EPA LCR rules (90th percentile copper <1.3 mg/L). No PFAS exceedances reported in recent CCRs; treatment includes coagulation, filtration, chloramination, and fluoridation.
