WASTEWATER ANALYSIS

Analytical methods utilized by Colorado Analytical Laboratory satisfy NPDES requirements.  Metals are analyzed by ICP-MS and Atomic Absorption.  The lowest detection levels are obtained by ICP-MS and are normally in the ppb range. The most commonly tested parameters include the following:
