Rockford, DeKalb and Northern Illinois

Northern Illinois communities where municipal groundwater systems, local aquifers and regional distribution differences shape hardness, iron, radium and treatment questions.

Regional context

Use the regional hub, then verify the exact property

Northern Illinois communities where municipal groundwater systems, local aquifers and regional distribution differences shape hardness, iron, radium and treatment questions. The city pages below identify provider and source-water research starting points, but the current bill and PWSID remain the decisive identifiers.

Do not treat the metro as one water system. Communities within the same labor market can use Lake Michigan water, groundwater, river water, reservoirs or purchased supply from different wholesalers.
