Elevated salinity and nitrates in surface water and groundwater are increasing problems affecting much of California, other western states, and arid regions throughout the world. In California, as surface and groundwater supplies become scarcer, and as wastewater streams become more concentrated, salinity and nitrate impairments are occurring with greater frequency and magnitude.

In 2006, the Central Valley Water Board, the State Water Board, and stakeholders began a joint effort to address salinity and nitrate problems in California’s Central Valley and adopt long-term solutions that will lead to enhanced water quality and economic sustainability. Central Valley Salinity Alternatives for Long-Term Sustainability (CV-SALTS) is a collaborative basin planning effort aimed at developing and implementing a comprehensive salinity and nitrate management program. The goal of CV-SALTS is to maintain a healthy environment and a good quality of life for all Californians by protecting our most essential and vulnerable resource: WATER.

In July 2008, the Central Valley Salinity Coalition (CVSC) was formed.  CVSC represents stakeholder groups working with the Board in the CV-SALTS effort.  Its purpose is to organize, facilitate and fund efforts needed to fulfill the goals of CV-SALTS.  CVSC coordinates the meetings of the CV-SALTS committees, maintains an independent web site, and manages the projects originating from this effort.  Information and materials regarding the stakeholder committees and other activity, including the meeting schedule, are posted on their website: www.cvsalinity.org. 

Archives of initial CV-SALTS activities and meetings (2006-2008) will be posted on this site until further notice.

In January 2017, CV-SALTS developed and submitted a Central Valley-wide Salt and Nitrate Management Plan to the Central Valley Water Board. In March 2017, the Board adopted a resolution accepting the Salt and Nitrate Management and Plan (SNMP) and directing Board staff to initiate Basin Plan Amendments to incorporate recommendations from the SNMP into the Basin Plans.

In January 2018, a Board workshop was held to discuss the proposed Basin Plan Amendments to incorporate a Central Valley-wide Salt and Nitrate Control Program. The Central Valley Water Board adopted the proposed amendments in May 2018.

The Salt and Nitrate Control Program basin plan amendment is currently going through the State Water Board adoption process and will be followed with the OAL and U.S. EPA (as appropriate) adoption processes.

• Currently in the process of transmitting Resolution R5-2018-0034 to State Water Resources Control Board.
