Environmental Laboratory Accreditation Program (ELAP)
Last Update: March 5, 2014
ELAP provides evaluation and accreditation of environmental testing laboratories to ensure the quality of analytical data used for regulatory purposes to meet the requirements of the State's drinking water, wastewater, shellfish, food, and hazardous waste programs. The State agencies that monitor the environment use the analytical data from these accredited laboratories. The ELAP-accredited laboratories have demonstrated capability to analyze environmental samples using approved methods. ELAP is within CDPH's Division of Drinking Water and Environmental Management.
- ELAP Chief: CDPH is currently recruiting to fill the position of Chief of ELAP. Information on the minimum qualifications and the application process is at http://jobs.spb.ca.gov/spb1/vpos1/vadmin_moreinfo.cfm?recno=505390.
- Hexavalent chromium: Certified laboraties for testing hexavalent chromium in drinking water are listed below. Public water systems outside of California should be aware that California's method currently uses a 1-ppb detection limit for purposes of reporting (DLR). However, analytical results at concentrations below the DLR may be reported when laboratories have associated quality assurance data for their results. Any modification to California’s current DLR will be associated with the hexavalent chromium maximum contaminant level (MCL), which is in the formal regulations adoption process. In addition, California concurs with USEPA’s temporary extension of the maximum holding time for properly preserved drinking water samples from 24 hours to 5 days. These recommendations may be revised once USEPA finalizes the re-evaluation of its hexavalent chromium analytical method for drinking water samples. Follow this link for additional information.
