Amendments to the Water Quality Control Plan for the Sacramento and San Joaquin River Basins to establish a Drinking Water Policy for surface waters of the Delta and its upstream tributaries. The Amendments include a new narrative water quality objective for the Cryptosporidium and Giardia, along with implementation provisions, as well clarification to the existing narrative water quality objective for chemical constituents. The amendments were approved by the State Water Board on 3 December 2013, the Office of Administrative Law on 19 May 2014, and by the US Environmental Protection Agency on 20 November 2014.

On 11 April 2013 a public hearing was held to receive comments on an amendment to the Water Quality Control Plan (Basin Plan) for the Sacramento River and San Joaquin River Basins to establish a Drinking Water Policy for Surface Waters of the Sacramento - San Joaquin Delta and Upstream Tributaries. The proposed Policy will be considered for adoption during the July 2013 meeting of the Central Valley Water Board.
Materials from the 2013 public hearing:
The Central Valley Drinking Water Policy Workgroup has finalized a report documenting and synthesizing the results of technical studies conducted to support the development of a Central Valley Drinking Water Policy (21 February 2012).
Source Control Evaluations
The following studies were conducted to provide inputs and refinements for modeling efforts evaluating various future scenarios and their impacts on drinking water treatment needs of Delta water. The wastewater and urban runoff studies include predicted future regulatory scenarios and cost estimates.

3 October 2006 Public Workshop
The intent of this workshop was to update interested stakeholders and the general public on the status of
development of the drinking water policy and related efforts and to obtain input.
The Drinking Water Policy Workgroup collaborates with several agencies to acquire and share data and modeling tools.
These agencies presented updates on their ongoing studies related to drinking water quality, some of which are posted below.
The Future for Drinking Water Contaminant Regulations, 1.68 MB*, PDF (PDF Info)
Bruce Macler, USEPA Region 9, delivered a presentation to the Central Valley Drinking Water Policy Workgroup on 11 December 2006. The presentation centered on how EPA develops regulations for contaminants of concern in
drinking water and how a drinking water regulation is initiated and promulgated including the information necessary to list a contaminant on the Candidate Contaminant List (CCL). Bruce concluded with a review of the
current status of various constituents on the CCL and emerging constituents of concern.
Conceptual Model for Salinity in the Central Valley and Sacramento San Joaquin Delta
Resolution in Support of Developing a Drinking Water Policy for the Sacramento-San Joaquin Delta and Upstream Tributaries
The purpose of the resolution is to show progress toward developing a policy and affirm the Regional Board's commitment to the effort.
