Drinking Water Monitoring
Drinking Water Monitoring
The Public Drinking Water Branch's monitoring section is charged with ensuring Missouri public water supplies comply with state and federal rules and regulations and provide safe drinking water to all citizens.
Individual water systems are required to submit samples of their water for laboratory testing to verify the water they are serving to the public meets all federal and state standards. How often and where samples are taken varies by system and contaminant.
