For the latest quarter assessed by the U.S. EPA (January 2021 - March 2021), tap water provided by this water utility was in compliance with federal health-based drinking water standards. UTILITY DETAILS * Baltimore, Maryland * Serves: 1,600,000 * Data available: 2014-2019 * Source: Surface water CONTAMINANTS DETECTED 9 EXCEED EWG HEALTH GUIDELINES 25 Total Contaminants * Legal does not necessarily equal safe. Getting a passing grade from the federal government does not mean the water meets the latest health guidelines. * Legal limits for contaminants in tap water have not been updated in almost 20 years. * The best way to ensure clean tap water is to keep pollution out of source water in the first place.
