Welcome to the State of California 

Division of Drinking Water and Environmental Management

CDPH's Division of Drinking Water and Environmental Management (DDWEM) promotes and maintains a physical, chemical, and biological environment that contributes positively to health, prevents illness, and assures protection of the public.

On July 1, 2014, the Drinking Water Program and the Environmental Laboratory Accreditation Program moved from CDPH to the State Water Resources Control Board (SWRCB). Find out more at http://www.swrcb.ca.gov/drinkingwater/index.shtml.
