Water Quality Reports
The Village is dedicated to supplying drinking water that meets or exceeds all state and federal standards. Each year, the U.S. Environmental Protection Agency requires communities to prepare a Consumer Confidence Report that provides information on the quality of the local drinking water.
In addition to detailed analyses of substances in the water, the report also includes facts about the community's drinking water delivery system and source, which for Oak Park, is Lake Michigan.
Links to the current and past reports are listed below. Reports are published the year following the testing, typically in late spring or early summer. The dates below reflect the year when testing was conducted.
For more information on Oak Park's drinking water, call 708.358.5700 or email publicworks@oak-park.us.
