Regional context

Use the regional hub, then verify the exact property

Lake Michigan communities north of Chicago, including direct treatment systems and municipal distribution systems that may purchase water from neighboring suppliers. 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.
