EWG's Tap Water Database — 2021 UPDATE

Donate

City of Deer Park

EWG's drinking water quality report shows results of tests conducted by the water utility and provided to the Environmental Working Group by the Texas Commission on Environmental Quality, 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.

Utility Details

  • Deer Park, Texas
  • Serves: 32,964
  • Data available: 2013-2019*
  • Source: Purchased surface water

    • * 2013 testing is for chemicals in EPA's Third Unregulated Contaminant Monitoring Rule (UCMR-3) only.

  • 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.
