What Makes Lincolnwood's Water Unique?
Local geology and source profile
The Village of Lincolnwood receives its water supply from the City of Evanston, which draws directly from Lake Michigan. This vast freshwater lake serves as the primary source, with water undergoing treatment at Evanston's facilities before being distributed to Lincolnwood residents through local mains. The Village of Lincolnwood itself does not operate its own water treatment plant, relying entirely on the processed water purchased from its neighbor. The service area encompasses about 2.9 square miles and serves approximately 12,500 people.
The region's water is shaped by its underlying geology. Illinois is characterized by glacial drift deposits from the Pleistocene epoch, including layers of sand, gravel, and clay. These unconsolidated sediments sit atop ancient Paleozoic bedrock, specifically Silurian reef dolomites and Niagaran limestones. These carbonate rock formations are known to dissolve minerals like calcium and magnesium into the water, contributing to its hardness despite the dilution effect from the large volume of Lake Michigan.
Homeowners in Lincolnwood may notice scale buildup on faucets and inside appliances like water heaters and dishwashers, which can reduce their efficiency by as much as 20-30% over time. White deposits on kettles and showerheads are common signs of this hard water. While regular cleaning with vinegar can help manage scale, installing a water softener is often recommended to prevent spotting on glassware and extend the lifespan of plumbing and fixtures. Annual maintenance checks on plumbing are also a good idea, especially if low-flow fixtures are installed.
Geology & Source: Lake Michigan watershed; Silurian dolomite and limestone bedrock produce hard water

Data Sources & Methodology
Water quality data for Lincolnwood 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.
