Public Drinking Water Testing

Public drinking water supplies are tested for bacteria on a monthly basis for Total Coliform and E. coli bacteria to comply with the State and US Environmental Protection Agency's Safe Drinking Water Act. The Missouri State Public Health Laboratory (MSPHL), US EPA certified laboratory # MO 00003, and its Southeastern Branch Lab in Poplar Bluff, US EPA certified laboratory # MO 00071, test approximately 60,000 public water samples annually. These services are provided as part of an interagency agreement with the Missouri Department of Natural Resources (MO DNR). 

For more information on public drinking water systems and compliance testing requirements, contact the Missouri Department of Natural Resources' Public Drinking Water Branch.
