EWG's Tap Water Database

Donate

City of Flint

 

EWG's drinking water quality report shows results of tests conducted by the water utility and provided to the Environmental Working Group by the Michigan Department of Environmental Quality, as well as information from the U.S. EPA Enforcement and Compliance History database (ECHO). For the latest quarter assessed by the EPA (January to March 2017), tap water provided by this water utility was in compliance with federal health-based drinking water standards.

This water utility buys or otherwise receives some or all of its finished water from one or more public water utility systems. EWG research suggests that this utility purchases water from a single supplier, City of Detroit. Tap water results displayed on the utility page show the water quality testing conducted by the original water supplier and this utility.
