Information for Public Drinking Water Systems

Foot Bridge to Intake Structure Any facility that serves water to 25 or more people a day for more than 60 days per year is a public water system.  The federal Safe Drinking Water Act establishes requirements for public drinking water systems, and the Maryland Department of Environment has primacy authority for enforcing the federal requirements.  Protection of drinking water involves using the best possible source and protecting that source from contamination, ensuring adequate supplies for the demand, conducting routine monitoring of water quality, regularly inspecting water treatment infrastructure, and ensuring that consumers are informed about their drinking water.
