“Analyzing the Unknowns and Making Them Known, Understood, and Manageable”

For over 45 years, our main laboratory has provided analytical services to a wide variety of industries, as well as engineers, municipalities and property owners. Using the latest technology, as well as classic wet chemistry techniques, the inorganic laboratory routinely performs analyses on drinking water, wastewater, surface wipe samples, soils, raw materials, and construction and demolition debris. The majority of the methods used are derived from EPA, ASTM, and Standard Methods.

The testing capabilities of this lab division are listed below. For more information regarding organics testing, such as semi-volatiles and VOCs, please visit our Organic Testing Lab page
