Abstract
The shallow aquifer in Lake County is a combined system of glacially deposited sands and gravels overlying fractured dolomite bedrock. This aquifer system provides drinking water to an estimated 50,000 private wells and hosts natural (geogenic) and human-sourced contaminants. Thirty monitoring wells were sampled in summer 2022 for inorganic constituents, non-purgeable organic carbon, and water isotopes. Nearly all wells were on public lands in natural areas owned by county governments. This report also reviews past water quality groundwater data pertaining to Lake County housed at the Illinois State Water Survey (ISWS).
