* There is no statewide requirement for a specific laboratory test. Contact the lead agency for guidance. Note: Soil and water analyses must be conducted by a California DHS accredited Laboratory. Contact the California DHS Environmental Laboratory Accreditation Program (ELAP) at 510-540-2800.

Note: California does not have state standard cleanup levels. Values shown are recommended action levels from the LUFT Field Manual. Cleanup levels are site specific. California has 9 Regional Water Quality Control Boards and 104 local agencies throughout the state. The Regional Water Quality Control Board is generally the lead on complex unauthorized UST releases, groundwater cases and cases referred to them by the local agency. Larger implementing local agencies with staff, expertise, and Regional Water Quality Control Board concurrence may be the lead in overseeing corrective action to these cases. The jurisdiction or Regional Water Quality Control Board enforces site specific cleanup levels, detection levels, etc. If groundwater is contaminated, often times, drinking water standards or MCL's are imposed
