LA Lab Accreditation

The Louisiana Environmental Laboratory Accreditation Program is designed to ensure the accuracy, precision, and reliability of the data generated, as well as the use of the department-approved methodologies in the generation of that data. Laboratory data generated by commercial environmental laboratories that are not accredited under these regulations will not be accepted by the department in accordance with LAC 33:I.4501.A.2. Whenever samples are subcontracted to another environmental testing laboratory, the original laboratory shall maintain a verifiable copy the results with a chain of custody. The subcontracting procedure may not be used to circumvent proper accreditation or any state requirements. The original laboratory is responsible for ensuring that the secondary laboratory used is properly accredited for the scope of testing performed in accordance with LAC 33:I.5307.D.

** The laboratory accreditation data is being pulled in real time from a separate server, so delays in processing requests should be expected
