Godfrey Water Hardness & Quality Report (2026)

Godfrey Water Department, part of the Village of Godfrey in Madison County, Illinois, supplies approximately 5,000 connections across residential, commercial, and industrial users located about 20 miles north of St. Louis, Missouri. The primary sources are multiple municipal wells tapping groundwater aquifers, with treatment occurring at the local Water Treatment Plant on Godfrey Road. There are no surface water intakes; the system relies entirely on wells screened into glacial drift and bedrock aquifers. Godfrey operates independently from larger regional providers such as American Water, which serves nearby systems.

Godfrey's groundwater sits within the Upper Mississippi River Basin, with recharge via precipitation infiltrating glacial deposits and fractured limestone of Mississippian age, including the Burlington and Keokuk formations — prolific karstic aquifers in western Illinois. These dolomitic limestones naturally impart a hard character through prolonged contact with calcium- and magnesium-bearing minerals. The St. Louis Limestone and overlying Pennsylvanian coal measures, blanketed by Pleistocene Illinoisan glacial till and outwash, channel surface-derived minerals into the aquifer, yielding a mineralised profile typical of Midwestern carbonate terrains.

Very hard water causes significant scale buildup, manifesting as white crusts on fixtures, reduced pipe flow, and encrustation inside appliances. Water heaters, dishwashers, washing machines, and coffee makers suffer most, with efficiency losses up to 30% from insulated heating elements. Maintenance involves monthly vinegar soaks for aerators and showerheads and annual descaling of water heaters. A water softener is strongly recommended to prevent spotting and reduce detergent use by up to 50%. Godfrey's water meets EPA standards for pH (7.2–7.8), complies fully with the Lead and Copper Rule, and reports no PFAS detections above advisory levels; the system earns high marks in state audits with no violations in the past five years.
