Four Columbia Analytical Laboratories Receive DoD-ELAP Certificates of Accreditation

KELSO, Wash. – Columbia Analytical Services, Inc. announced today that four of its laboratories have met the requirements of the Department of Defense (DoD) Environmental Laboratory Accreditation Program (ELAP) and each have been awarded a certificate of accreditation.

The recently accredited laboratories are located in Houston, Texas, Simi Valley, Calif., Rochester, N.Y., and Kelso, Wash. Columbia Analytical’s Houston facility is dedicated to high resolution analyses of analytes such as dioxin, furans and PCB congeners and the Simi Valley laboratory specializes in the analysis of ambient and indoor air pollution, stationary source emissions, process gas, and industrial hygiene samples. The Rochester facility, a full service laboratory, also offers air analyses and other specialized testing like that for perchlorate by LC/MS. The Kelso laboratory became DoD-ELAP accredited in November 2009 and specializes in non-routine, complex low-level analyses requiring a high degree of technical expertise.

The full scope of accreditation, including the list of analytes to which these accreditations apply, may be found on Columbia Analytical’s DoD ELAP webpage.

Columbia Analytical is an employee-owned, full-service environmental analytical laboratory testing network established in 1986 and headquartered in Kelso, Washington. Their expertise encompasses air, water, dioxin, biological, pharmaceutical, solid and hazardous waste analyses.
