* Correction Statement: Our 2017 Consumer Confidence Report listed the 90th percentile for lead as <2 parts per billion (ppb). The correct value for our system’s most recent 90th percentile should have been listed as 4.3 ppb, which is still below the 15 ppb action level for lead. We apologize for this error. The Oak Park - 2018 Annual Water Quality Report link above contains a corrected copy of the Report.

The City of Oak’s Complete Distribution System Material Inventory (CDSMI) report shows the city is free of any known lead service lines.

While the program requires the city to verify 370 random water service lines throughout our system, the link below shows the progress we have made as of October 16, 2024:
