Division of Consolidated Laboratory Services


The Division of Consolidated Laboratory Services (DCLS) supports public health by certifying non-commercial laboratories that demonstrate compliance with applicable regulations. The certification program for non-commercial laboratories ensures that laboratories have quality systems and analytical procedures in place which support the production of accurate, reliable, and defensible test results.

Who Should Apply

  • Non-Commercial laboratories providing testing for the purpose of compliance with the Virginia Air Pollution Control Law, the Virginia Waste Management Act or the State Water Control Law (§ 10.1-1300 et seq., § 10.1-1400 et seq., and § 62.1-44.2 et seq., respectively, of the Code of Virginia) are required to hold accreditation under 1VAC30-45.
  • The regulation at 1VAC30-45-40 defines non-commercial laboratories. Typically a non-commercial laboratory is a municipal or industrial laboratory providing analytical data for its owner holding a permit issued by Virginia Department of Environmental Quality (VA DEQ).
