Clark County sits across the Ohio River from Louisville, KY, home to about 120,000 residents in communities like Jeffersonville, Clarksville, and New Albany (partially). The Indiana American Water company draws from the Ohio River to serve much of the county, though some communities maintain independent groundwater systems.
The Ohio River at Clark County has already traveled past Pittsburgh, Cincinnati, and Louisville's industrial waterfronts. UCMR5 data shows low-level PFAS detections in county systems. Indiana does not have state-specific PFAS standards, relying on federal guidelines.
According to the Indiana Department of Environmental Management's 2024 compliance data, county systems met federal standards. The Ohio River's complex contaminant profile means treatment must address a wider range of compounds than cleaner source waters require. Disinfection byproducts from treating organic-rich river water are a seasonal management challenge.
The Ohio River's complexity as a water source means treatment quality matters significantly.
Check your water for data in your area. An activated carbon filter helps with taste and DBPs. For PFAS, reverse osmosis provides broader coverage. Our water filter guide covers options. Pull your detailed report, and visit our Indiana page for statewide data.
