Unregulated Contaminant Map

The containment map was generated using data from the Unregulated Contaminant Monitoring Rule (UCMR3), an initiative by the U.S. Environmental Protection Agency that gathered data from public water systems reporting unregulated contaminants. Click on each step to find the contaminants in the area you wish to select.
