EWG's Tap Water Database — 2021 UPDATE

Donate

Jackson County PWSD 2

EWG's drinking water quality report shows results of tests conducted by the water utility and provided to the Environmental Working Group by the Missouri Department of Natural Resources - Public Drinking Water Program, as well as information from the U.S. EPA Enforcement and Compliance History database (ECHO). 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.

  • 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.
