Gasconade PWS

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 2019 - March 2019), tap water provided by this water utility was in compliance with federal health-based drinking water standards.

GUIDELINES

5 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.

Legal ≠ Safe

EWG Health Guidelines fill the gap in outdated government standards.

The federal government’s legal limits are not health-protective. The EPA has not set a new tap water standard in almost 20 years, and some standards are more than 40 years old.

Tribromoacetic acid

more about
this contaminant

Tribromoacetic acid is formed when chlorine or other disinfectants are used to treat drinking water. Disinfection byproducts increase the risk of cancer and may cause problems during pregnancy.

Tribromoacetic acid was found at 50 times above EWG's Health Guideline.
