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. Microbiology Analytical Unit Parameters Alkalinity (includes bicarbonate and carbonate) Biochemical Oxygen Demand (BOD5-day) Specific Conductance (conductivity) Carbonaceous BOD (cBOD5-day) Coliform, Fecal (bacteria) Dissolved Organic Carbon (DOC) Coliform, Total (bacteria) Total Organic Carbon (TOC) Turbidity Metals Analytical Unit Parameters Aluminum Al Manganese Mn Antimony Sb Mercury Hg Arsenic As Mercury, low-level (see below) Barium Ba Molybdenum Mo Beryllium Be Nickel Ni Boron B Potassium K Cadmium Cd Selenium Se Calcium Ca Silver Ag Chromium, total Cr Sodium Na Cobalt Co Strontium Sr Copper Cu Thallium Tl Iron Fe Tin Sn Lead Pb Titanium Ti Lithium Li Vanadium V Magnesium Mg Zinc Zn Notes: Low-Level mercury (EPA method 1631) requires a separate sample kit; by request only Additional Information for Metals Analyses: Link to the Mercury Method 1631 Overview presentation by Roy Byrd Link to the NC Division of Epidemiology Fish Consumption Advisories site.
