Winthrop Harbor Water Quality Reports 

To ensure safe drinking water in the United States, federal regulations have guided intervention and regulatory efforts to successfully reduce exposure to water contaminants.

Each year the Village of Winthrop Harbor provides water customers with an Annual Water Quality Report. Our 2023 Water Quality Report has met all the USEPA drinking water requirements and standards. This report provides details about the source and quality of the drinking water delivered to our community in 2023.
