Reorganization Proposal: The Administration has proposed a July 1, 2014 transfer of the Drinking Water Program from CDPH to the State Water Resources Control Board (SWRCB). Find out more at http://www.swrcb.ca.gov/drinkingwater/index.shtml.  The Environmental Laboratory Accreditation Program (ELAP) is also proposed to be transferred to SWRCB.  In this proposal the other branches in DDWEM -- the Environmental Management Branch and the Drinking Water and Radiation Laboratory -- will remain in CDPH.

The California Department of Public Health'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.

Here's DDWEM's organization (PDF) Opens in new window.for quick reference and program contacts.  DDWEM's major components are:

  • Drinking Water Program. The Drinking Water Program regulates public water systems; promotes and provides information on drought preparedness and water conservation; oversees water recycling projects; certifies residential water treatment devices; certifies drinking water treatment and distribution operators; supports and promotes water system security; provides support for small water systems and for improving technical, managerial, and financial (TMF) capacity; oversees the Drinking Water Treatment and Research Fund for MTBE and other oxygenates; and provides funding opportunities for water system improvements, including funding under Proposition 84, Proposition 50 and the Safe Drinking Water State Revolving Fund.
  • Environmental Management Branch (EMB). EMB regulates medical waste generators, shellfish production and harvesting operations, and recreational health (swimming pools and ocean beaches); provides sanitary surveillance of state institutions; oversees radiological surveillance around federal facilities, the state's radon program, and the Medical Waste Management Program; and houses CDPH's Nuclear Emergency Response Program.
  • Drinking Water and Radiation Laboratory (DWRL). DWRL provides analytical support to the DDWEM's programs and CDPH's Radiological Health Branch, and, through interagency agreements, to other State agencies. DWRL was formerly known as the Sanitation and Radiation Laboratory.
  • Environmental Laboratory Accreditation Program (ELAP). ELAP provides evaluation and accreditation of environmental testing laboratories to ensure the quality of analytical data used for regulatory purposes to meet the requirements of the State's food, drinking water, wastewater, shellfish, and hazardous waste programs.
