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.

Nitrate Project Interagency Task Force (ITF)

Member agencies of the ITF are identified in the legislation include:
