The ALS laboratory in Simi Valley, California is a nationally recognized, 22,000 square foot air testing laboratory specializing in the analysis of ambient and indoor air pollution, stationary source emissions, process gas, and industrial hygiene samples.
The laboratory has performed testing on projects for clients in all 50 United States, Puerto Rico, Guam, and several other countries. In addition, ALS has provided analytical support to colleges and universities located throughout the United States. ALS is accredited by the National Environmental Laboratory Accreditation Program (NELAP), and the US Department of Defense (DoD).
The Simi Valley laboratory provides analytical support for routine applications such as ambient air, remediation, landfills, soil vapor extraction (SVE), site characterization, source emissions testing, indoor air quality, waste water, treatment plants, fence-line ambient and residential monitoring, and government projects (AFCEE, ACOE, Navy).
The laboratory maintains an inventory of nearly 4,000 pre-cleaned passivated stainless steel canisters of various sizes, low volume flow controllers and critical orifice assemblies, analog vacuum gauges, and a wide assortment of solid sampling media.
In addition to routine air testing, ALS in Simi Valley performs a wide variety of specialized tests including the low level analysis of odorous compounds; compliance testing for the pulp and paper industry; measurement of thermal decomposition products from aviation and hydraulic fluids for the aerospace industry; and material off-gas testing of building materials and commercial and consumer products. The air laboratory maintains a separate off-site extraction laboratory. Utilizing a separate extraction facility minimizes the use of volatile solvents and other chemicals at the analytical laboratory, thereby enabling the laboratory to achieve low parts per billion or parts per trillion detection of volatile organic compounds in a contaminant-free environment.
As part of the expansion of the Simi Valley facility, analytical capabilities have been added for a limited number of analytical procedures for soil and water samples, primarily volatile organics and general wet chemistry methods.
