Environmental Laboratory Accreditation Program (ELAP)
CA State Program
The California Environmental Laboratory Improvement Act (Department-sponsored Assembly Bill 3739, Chapter 894, Statutes of 1988) took effect on January 1, 1989. It established within the Department of Health Services (now CDPH) a consolidated fee-supported accreditation program for environmental health laboratories, and a special fund, the Environmental Laboratory Improvement Fund, to support the program. Under the Act, accreditation is required of an environmental laboratory for producing analytical data for California regulatory agencies, such as Division of Drinking Water and Environmental Management (DDWEM), Department of Toxic Substances Control in California Environmental Protection Agency, State Water Resources Control Board, Regional Water Quality Control Boards, and California Department of Food and Agriculture. The data may be used to demonstrate compliance with applicable requirements of drinking water, wastewater, food for pesticide residues, shellfish testing, and hazardous waste sections of the California Health and Safety and Water Codes.
A laboratory seeking accreditation must submit a completed application form, a quality assurance manual, and appropriate fees. The fee schedule (Excel) is based on the number of fields of testing (FOT) applied for, and due at the time of application and annually thereafter. The base fee is $1003.00 and the FOT fee is $452.00 for each FOT. A site visit is then conducted by the ELAP technical staff. The laboratory must take corrective actions for the deficiencies found. The laboratory is also required to participate successfully in performance evaluation (PE) studies. The PE samples must be successfully analyzed prior to the granting of certification and annually thereafter for all applicable test parameters for which PE samples are available. A certificate is issued for a period of two years based upon completion of the application process, verification of the quality assurance program, successful completion of the site visit, and acceptable analytical performance on the appropriate PE samples.
A laboratory desiring to add one or more subgroups within a FOT to its current certificate must submit a completed amendment application form with appropriate fees. A site visit and PES evaluation follow as described above. The application forms for certification and for amendment, and instructions for completing the forms can be obtained from the ELAP web site.
ELAP also conducts investigations and takes enforcement actions as warranted. Further, ELAP provides technical consultations and regulatory updates to the environmental laboratory community. ELAP also provides information on certified laboratories to government agencies and the general public.

Reciprocity allows ELAP to recognize accreditation of environmental laboratories granted by other states or U.S. government agencies. This process of accreditation through reciprocity saves considerable resources and still meets the needs of the program. ELAP has reciprocity agreements of varying scope with the following states:
- Washington State Departments of Ecology and of Health: Drinking Water, Wastewater, Hazardous Waste, Bioassay/Toxicity
- Nevada Department of Human Resources: Drinking Water
