List: Maximum Contaminant Levels (California Safe Drinking Water Act)
Description
The California Safe Drinking Water Act (CA SDWA) was passed to build on and strengthen the federal Safe Drinking Water Act (SDWA). The CA SDWA authorizes the state's Department of Health Services (DHS) to protect the public from contaminants in drinking water by establishing maximum contaminants levels (MCLs) that are at least as stringent as those developed by the U.S. EPA, as required by the federal SDWA.

The California DHS lists any contaminants that may have any adverse health effects, based on expert opinion, and may occur in public water systems, including all the substances for which federal MCLs exist.
