Biography

Tony R. Lee is a Physical Scientist in GWERD's Subsurface Remediation Branch. Mr. Lee has a B.S. in Environmental Science from East Central University and a M.S. in Environmental Science from the University of Oklahoma. Previously, he worked as a Project Scientist for ManTech Environmental Technology, Inc. (10 years), where he conducted research on the identification of ribosomal RNA/DNA from subsurface microorganisms while using Gel Electrophoresis/High Pressure Liquid Chromatography techniques. Mr. Lee is also a Class B Certified Waste Water Operator with the State of Oklahoma (Department of Environmental Quality).

Since April 1999, Mr. Lee has been employed with the Environmental Protection Agency as an Environmental/Physical Scientist. He is working with the Enhanced Source Removal (DNAPL) group while concentrating his investigations on co-solvent and surfactant flushing of residual tetrachloroethylene (PCE) with the micromodel/2-D flow model systems. The micromodel system includes a fiber optic imaging system which records the visual effects of mobilization and solubilization of PCE in the micromodel during the flushing processes. The 2-D flow model system includes Light Transmission Visualization/Optical Imaging techniques for the identification of residual PCE for various flushing procedures. The DNAPL work has involved both field and laboratory studies, and has focused on six separate sites; 1) Jacksonville, FL, 2) Dover AFB, DE, 3) Camp Lejeune, NC, 4) Cape Canaveral, FL, 5) Fort Lewis, WA, and 6) Hill AFB, UT. The work done at these sites involves groundwater sampling of multi level samplers, flux pump tests, installation of multi-level samplers/wells, core sampling (including microbial core sampling techniques), partitioning tracer tests, and DNAPL controlled release techniques (Dover site). Mr. Lee is currently working on the Scanning Electron Microscope (2004 – Present) to identify diatom, sediment (arsenic identification), and iron filing samples (Permeable Reactive Barrier) with secondary/backscatter detectors and EDX (x-ray) elemental mapping software. The identification of elemental weight %, atomic %, and the mapped location of the element in the Region of Interest can be achieved with the EDX detector/software.

Mr. Lee is the Alternate Radiation Safety Officer at Kerr Lab and helps to ensure a safe and compliant radioactive-licensing program at GWERD.
