The Division of Consolidated Laboratory Services (DCLS) was directed by Section 2.2-1105 of the Code of Virginia to establish a program to certify environmental laboratories that perform tests, analyses, measurements or monitoring required pursuant to the Commonwealth's air, waste and water laws and regulations. The program became established on January 1, 2012.
The Virginia Environmental Laboratory Accreditation Program (VELAP) carries out the administration of two chapters of the Virginia Administrative Code. These chapters set out the required standards and the processes by which laboratories become accredited or certified and by which laboratories maintain that accreditation or certification.
