Microbiology & Metals Unit
Unit Supervisor: Joe Jurgevich
Comprised of the Metals and Microbiology analytical groups.
Responsible for analysis of water samples for the parameters listed below utilizing a variety of analytical systems and procedures that include AA Furnace, ICP, ICP/MS, automated combustion catalytic oxidation, membrane filtration, and titration.
In addition to analyzing aqueous samples for total and dissolved metals, the Metals Unit also analyzes non-aqueous and fish tissue samples. The Metals Unit houses a Class-1000 clean room for the analysis of mercury at the parts per trillion level.
