The Public Water Supply Program ensures safe drinking water to the 2.8 million citizens of Mississippi who utilize the state's public water supplies by strictly enforcing the requirements of the Federal and State Safe Drinking Water Acts (SDWAs).

The Public Water Supply Program is implemented through five major programmatic areas:

• microbiological, chemical, and radiological monitoring of drinking water quality;
• negotiation with consulting engineers on the final design of engineering plans and specifications for all new or substantially modified public water supplies;
• annual surveys of each community public water supply to identify and eliminate operational and maintenance problems that may potentially affect drinking water quality;
• enforcement to ensure that all public water supplies follow SDWA standards; and
• licensure of waterworks operators and backflow assembly testers and training of water supply officials, consulting engineers, and MSDH environmental staff in the proper methods of designing, constructing, and operating public water systems.

The Public Water Supply Program also provides all administrative support necessary to manage the State Drinking Water Revolving Fund Loan Program.
