Nitrate in Groundwater:
Pilot Projects in Tulare Lake Basin/Salinas Valley-SBX2 1
Current Efforts Addressing Nitrate
Nitrate contamination in soil and groundwater has been a concern of the Regional Water Boards for some time. These two fact sheets outline how the Central Valley and Central Coast Regional Water Quality Control Boards are currently addressing nitrate.
Develop Nitrate Pilot Projects in the Tulare Lake Basin and Salinas Valley
Water Code Section 83002.5 (SBX2 1) requires that the State Water Board, in consultation with other agencies, develop pilot projects in the Tulare Lake Basin and the Salinas Valley to study nitrate contamination, and identify remedial solutions and funding options to recover costs associated with cleanup or treatment of groundwater and to report to the Legislature within two years. It also directs the State Water Board to create an interagency task force (ITF) as needed, to oversee the pilot projects and develop recommendations for the Legislature.
The pilot projects are intended to help improve understanding of the causes of groundwater contamination due to nitrate, identify potential source reduction measures, remediation and treatment solutions, and funding sources to recover costs expended by the state to clean up or treat groundwater, and ensure the provision of safe drinking water to all communities.
Nitrate Project Development
The State Water Board contracted the UC Davis Land, Air and Water Resources to conduct an independent investigation in these areas and report on the findings and potential solutions for nitrate in groundwater. Dr. Thomas Harter, Professor of Hydrogeology, is the principal investigator.
Member agencies of the ITF are identified in the legislation include:
- California Environmental Protection Agency
California Department of Food and Agriculture
- California Department of Public Health
- California Department of Pesticide Regulation
- California Department of Toxic Substances Control
- California Department of Water Resources
- Fresno County Department of Public Health
- Kern County Department of Public Health
- Kings County Department of Public Health
- Monterey County Health Department
- Tulare County Health Services
- State Water Resource Control Board
- Central Coast Regional Water Quality Control Board
- Central Valley Regional Water Quality Control Board
Although the ITF is not a state body subject to open meeting laws, the ITF will conduct its work in a manner that is transparent to the public to the extent practicable. The State Water Board would like to thank all of those who participate in these events.
