Environmental Laboratory Accreditation Program (ELAP)

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 which 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.

The National Environmental Laboratory Accreditation Program (NELAP) granted recognition of ELAP on July 1, 1999, to be the NELAP Accrediting Authority for California.
