The department’s Public Drinking Water Branch has the important mission of ensuring Missouri’s more than 2,700 public water systems provide safe drinking water to every resident and visitor in the state. To do this, the branch monitors for contaminants, issues permits for new and existing public water systems, certifies drinking water treatment and distribution operators, supports and promotes water system security, provides support for improving technical, managerial, and financial capacity, and provides funding opportunities for water system improvements. Our aim is to help keep you informed of the quality of Missouri's drinking water.

Information regarding private water and private water supplies as well as private water testing to homeowners and local public health agencies is available on the Department of Health and Senior Services' Private Drinking Water Bacteriological Testing webpage.
