Regional context

Use the regional hub, then verify the exact property

Mississippi River communities and western Illinois groundwater markets where source-water type, wholesale arrangements and distribution systems vary by city. 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.
