Safe Drinking Water Act

Drinking Water Quality

The Safe Drinking Water Act (SDWA) regulates the quality of drinking water delivered by cities, towns and municipalities. It also regulates community water systems including housing complexes, schools and transient water systems serving more than 25 people.
