What is Environmental Laboratory Licensure?

Environmental laboratory licensure is designed to help protect the Public Health and Environment by surveying all licensed laboratories for compliance with all applicable regulations and reviewing their compliance testing data for scientific validity and defensibility.

Who should be licensed?

Environmental laboratories that perform testing on compliance samples in drinking water, wastewater, hazardous waste and air are required to be licensed by the State of Arizona. Compliance testing is defined in A.R.S. § 36-495.

Where can I find Arizona's environmental laboratory regulations?

Regulations may be found on the Environmental Laboratory Licensure home page or by contacting the Secretary of State at (602) 542-4751 or AZSOS.gov.

Statutes may be found by visiting the Arizona State Legislature and looking at Title 36 Chapter 4.3.

Does the State of Arizona accept reciprocity from other states? from NELAC Institute?

Arizona does not currently accept reciprocity from any state or organization that licenses environmental laboratories. Laboratories that do not need an Arizona license are those that perform asbestos testing, except in drinking water, and are National Voluntary Laboratory Accreditation Program (NVLAP) accredited ( A.R.S. § 36-495.02(A)).
