What Makes Lyons's Water Unique?
Local geology and source profile
The Village of Lyons serves around 10,000 residents in Cook County, Illinois, and surrounding areas with purchased treated surface water. The utility, reachable at 708-442-4500, does not perform local treatment, relying on regional providers for its supply. These sources are part of the Chicago metropolitan watershed, potentially drawing from the Des Plaines River or Lake Michigan allocations. Annual Consumer Confidence Reports for 2022 and 2023 confirm compliance with all federal drinking water standards, with disinfection using chloramines and hypochlorite.
The water's journey begins in the Chicago metropolitan watershed, which includes the Des Plaines River sub-basin. This area's geology features Wisconsinan glacial till and outwash overlying Silurian-age Niagaran dolomite and dolomitic limestone formations. These prevalent carbonate rock layers naturally dissolve, releasing alkaline earth metals like calcium and magnesium. This geological characteristic results in a supply that is naturally hard, with minimal softening effects from other soil types.
Homeowners in Lyons will notice the impact of this very hard water primarily through scale buildup in appliances such as dishwashers, washing machines, and water heaters, which can reduce their efficiency and lifespan. Faucet aerators and showerheads often become clogged, affecting water flow. To manage this, monthly vinegar descaling of fixtures is recommended, along with annual professional flushing of water heaters. For a more comprehensive solution, installing a whole-house water softener is advisable to prevent spotting, extend appliance life, and improve soap lathering, though it requires ongoing salt refills.
Geology & Source: Pleistocene glacial drift over Paleozoic Silurian dolomite and limestone; carbonate bedrock leaches calcium and magnesium, producing hard water

Data Sources & Methodology
Water quality data for Lyons 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.
