CA ELAP Laboratory Assessment Program


The California Environmental Laboratory Accreditation Program (ELAP) Laboratory Assessment Program is a program developed by the California Department of Public Health (CDPH) to accredit laboratories that perform environmental testing in the state of California. The ELAP Laboratory Assessment Program is designed to ensure that laboratories that perform environmental testing have the necessary expertise and resources to accurately and reliably test environmental samples.

CA ELAP Laboratory Assessment Program

To become an accredited laboratory under the ELAP Laboratory Assessment Program, a laboratory must demonstrate that it has the necessary personnel, equipment, and procedures in place to perform environmental testing. This may include demonstrating expertise in specific areas of environmental testing, having a robust quality management system in place, and having the necessary equipment and personnel to perform testing and evaluations.

Accredited laboratories under the ELAP Laboratory Assessment Program are required to undergo regular evaluations to ensure that they continue to meet the necessary standards and are able to accurately and reliably test environmental samples. This helps to ensure that the results of environmental testing in California are reliable and accurate, which is important for both consumers and regulators.
