The Water Supply Program is part of the Water Management Administration within the Maryland Department of the Environment (MDE). The mission of the Water Supply Program is to ensure that public drinking water systems provide safe and adequate water to all present and future users in Maryland, and that appropriate usage, planning and conservation policies are implemented for Maryland's water resources. This mission is accomplished through proper planning for water withdrawal, protection of water sources that are used for public water supplies, oversight and enforcement of routine water quality monitoring at public water systems, regular onsite inspections of water systems, and prompt response to water supply emergencies. The Water Supply Program's activities help to ensure safe drinking water for more than 5.7 million Marylanders. For more general facts on Maryland Drinking Water, click here.
