What Makes Campbellsville's Water Unique?
Local geology and source profile
Campbellsville Municipal Water supplies the city of Campbellsville in Taylor County, Kentucky, serving about 25,385 residents. The Campbellsville Water Treatment Plant, located at 135 City Park Rd., has a capacity of 9.0 million gallons per day. Its primary source is Green River Reservoir on Smith Ridge, with City Lake on Lebanon Avenue serving as a backup. Both are surface water supplies drawn from the Green River watershed, which drains karst landscapes within the Western Coal Field. These waters are treated to meet EPA standards before reaching homes.
The region's geology is characterized by Mississippian limestones and dolomites, including formations like the Ste. Genevieve and Bethel limestones. Weathering and dissolution of this carbonate-rich bedrock naturally mineralize the surface water, contributing to its hardness. This contrasts with softer waters often found in areas dominated by sandstone or in glaciated regions. While no specific aquifer is named for this surface water supply, the underlying bedrock significantly influences its chemical composition.
Homeowners in Campbellsville may notice reduced soap lathering and soap scum in bathrooms due to the water's hardness. Scale buildup is common in appliances like dishwashers, washing machines, and water heaters, potentially shortening their lifespan by 30-50%. You might also see white deposits on faucets and inside kettles. Regular descaling with vinegar for fixtures, annual flushes for water heaters, and the use of low-flow aerators can help manage scale. For households concerned about hard water effects, installing a water softener is recommended to improve cleaning and extend appliance life. Campbellsville water quality reports, available at campbellsville.us/water-quality-reports, confirm compliance with all health standards.

Data Sources & Methodology
Water quality data for Campbellsville is derived from geographic and geological modelling of the surrounding region. No federal monitoring station data was available for this location.
Water Hardness
Modelled estimate based on state-level USGS geological survey data for this region. No direct USGS Water Quality Portal measurement was matched to this city — the value reflects a statistical range calibrated to the state's dominant rock types and typical source water characteristics.
pH
Estimated from regional geology and source water characteristics. pH is correlated with water hardness and local bedrock — values may differ from utility-reported figures.
TDS — Total Dissolved Solids
Estimated using a derived ratio from water hardness and regional conductance profiles. TDS in natural water correlates strongly with total mineral content including hardness ions.
PFAS — Perfluoroalkyl and Polyfluoroalkyl Substances
EPA UCMR5 (5th Unregulated Contaminant Monitoring Rule, 2023–2025) — sum of PFAS compounds detected at the public water system serving this city. A value of 0 indicates the system was sampled with no detection above reporting limits.
Lead
Modelled estimate based on the EPA Lead and Copper Rule 90th-percentile tap-sample methodology. No publicly available per-city lead dataset with sufficient national coverage exists. Values are a conservative baseline derived from city population tier and infrastructure age — all estimates are maintained below the EPA action level of 0.015 mg/L.
Appliance Lifespan
Calculated from water hardness using a linear degradation model. Baseline lifespans represent soft-water performance (kettle: 8.5 yrs, washing machine: 12.0 yrs, water heater: 15.0 yrs). Hard water mineral scale progressively reduces operational life in direct proportion to hardness concentration.
