Microbiology & Metals Unit

Comprised of the Metals and Microbiology analytical groups.

Responsible for analysis of water samples for the parameters listed below (the Metals group also analyzes soil/sediment and fish tissue samples) utilizing a variety of analytical systems and procedures that include AA Furnace, ICP, ICP/MS, automated combustion catalytic oxidation, membrane filtration, and titration.

Houses a Class-1000 clean room for analysis of mercury at the parts per trillion level.
