What Makes Pleasant Prairie's Water Unique?

Local geology and source profile

The Village of Pleasant Prairie Water Utility serves the Pleasant Prairie area in Kenosha County, Wisconsin. Rather than operating its own treatment plant, the utility purchases treated surface water from the City of Kenosha, which draws from Lake Michigan. The water is disinfected with chlorine and distributed through the municipal system serving residential, commercial, and industrial customers in the village. Annual Consumer Confidence Reports are published by July 1st on the Village of Pleasant Prairie website or available by contacting Public Works at 262.925.6700.

Pleasant Prairie's water supply originates from Lake Michigan, a Great Lakes source that passes through the region's glacial geology. The underlying bedrock consists primarily of Silurian-age dolomite formations, which are highly soluble and contribute significant dissolved minerals to groundwater and surface water alike. This geological setting is characteristic of southeastern Wisconsin and results in a naturally mineralized water supply with elevated hardness from calcium and magnesium carbonates typical of the region.

At hard water levels, scale buildup is noticeable in kettles, coffee makers, and showerheads, and soap does not lather efficiently. Appliances such as water heaters and dishwashers are particularly vulnerable to mineral accumulation and reduced efficiency. A water softener is recommended to protect plumbing infrastructure, extend appliance lifespan, and improve cleaning effectiveness. Regular maintenance of water-using appliances is important at this hardness level. The utility has reported at least one contaminant above EPA health-based guidelines; residents can obtain full details including pH, lead, and copper compliance results from the annual Consumer Confidence Report.

Geology & Source: Lake Michigan surface water source; Silurian-age dolomite formations underlying southeastern Wisconsin highly soluble — dissolved calcium and magnesium carbonates from glacial deposits and dolomite bedrock produce hard water typical of the region

Frequently Asked Questions

Is Pleasant Prairie's water safe to drink?
Yes. Pleasant Prairie's water meets all federal safety standards. The hardness is ≈ 120–179 mg/L (Hard), which is safe to drink. High hardness affects appliances and taste, but poses no health risk.
Do I need a water softener in Pleasant Prairie?
At ≈ 120–179 mg/L (Hard), Pleasant Prairie's water will cause significant limescale on kettles, washing machines, and water heaters. A water softener or descaler is strongly recommended to extend appliance lifespan and reduce energy bills by up to 20%.
How does Pleasant Prairie compare to the USA average?
The USA national average is 151 mg/L. Pleasant Prairie (≈ 120–179 mg/L) is 1 mg/L below the national average. The softest major city is Scarsdale at just 0.02 mg/L.

Data Sources & Methodology

Water quality data for Pleasant Prairie is derived from geographic and geological modelling of the surrounding region. No federal monitoring station data was available for this location.

Estimated

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.

Estimated

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.

Estimated

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.

Measured

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.

Modelled

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.

Calculated

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.
