CDPH's Drinking Water Program (DWP) is within the Division of Drinking Water and Environmental Management. DWP regulates public drinking water systems, but it doesn't regulate bottled water or vended water -- these are regulated as food by CDPH's Food and Drug Branch.

Private domestic wells are not regulated by DWP. The State Water Resources Control Board has information pertinent to private domestic well water quality.
DWP consists of three branches: (1) the Northern California Field Operations Branch, (2) the Southern California Field Operations Branch, and (3) the Technical Programs Branch.
Northern California & Southern California Field Operations Branches (FOBs)
Here is a map of FOB districts and office contact information (PDF).
The FOBs are responsible for the enforcement of the federal and California Safe Drinking Water Acts (SDWAs) and the regulatory oversight of ~7,500 public water systems to assure the delivery of safe drinking water to all Californians. In this capacity, FOB staff perform field inspections, issue operating permits, review plans and specifications for new facilities, take enforcement actions for non-compliance with laws and regulations, review water quality monitoring results, and support and promote water system security. In addition, FOB staff are involved in funding infrastructure improvements, conducting source water assessments, evaluating projects utilizing recycled treated wastewater, and promoting and assisting public water systems in drought preparation and water conservation. The Techinical Operations Section is located in the Northern California Field Operations Branch.
FOB staff work with the US Environmental Protection Agency (EPA), the State Water Resources Control Board, Regional Water Quality Control Boards (RWQCBs), and a wide variety of other parties interested in the protection of drinking water supplies. On the local level, FOB staff work with county health departments, planning departments, and boards of supervisors. Primacy has been delegated by CDPH to certain county health departments for regulatory oversight of small water systems, and FOB staff provide oversight, technical assistance, and training for the local primacy agency personnel.
The Technical Operations Section
The Technical Operations Sections administers its programs through the following units. Click on a link for contact information
Technical Programs Branch
The Technical Programs Branch is responsible for maintaining the scientific expertise of the Drinking Water Program and for administering the Safe Drinking Water State Revolving Fund and the Small Water Systems program. The branch is composed of the Technical Operations Section, the Infrastructure Financing and Inftrastructure Funding Administration Sections, and the Monitoring and Evaluation Unit.
Infrastructure Financing & Infrastructure Funding Administration Sections
These sections administer funding programs through the following units and activities (Click here for information about funding programs, pre-applications, and claims forms):
- The Safe Drinking Water State Revolving Fund (SDWSRF) Unit implements the SDWSRF Program, including funding from the federal American Recovery and Reinvestment Act of 2009 (ARRA), and administers portions of voter-approved funding initiatives from March 2000 (Proposition 13), November 2002 (Proposition 50), and November 2006 (Proposition 84).
- The Environmental Review Unit (ERU) is responsible for complying with the California Environmental Quality Act (CEQA) when a water supply permit is issued or a drinking water project is funded.
- The Technical Support Unit provides technical and TMF capacity development assistance, and administers the local primacy delegation program for small water systems.
Monitoring and Evaluation Unit
- MEU collects analytical results from laboratories, compiles, evaluates, and reports drinking water quality data from laboratories that monitor drinking water for public water systems.
- MEU disseminates data to FOB and other staff, preparing reports on findings and evaluations, and meets the US EPA's data reporting requirements under primacy.
