Tony R. Lee, Environmental Scientist

Phone: 580-436-8890

Mr. Lee is a Physical Scientist in GWERD's Subsurface Remediation Branch. He holds a B.S. in Environmental Science from East Central University and an M.S. in Environmental Science from the University of Oklahoma. Previously, he worked for ten years as a project scientist for ManTech Environmental Technology, Inc., 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’s Department of Environmental Quality.

Mr. Lee has been with EPA since April 1999. He worked with the Enhanced Source Removal/DNAPL (dense nonaqueous-phase liquid) 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 that 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 involved both field and laboratory studies, and focused on six separate sites: Jacksonville, Florida; Dover Air Force Base, Delaware; Camp Lejeune, North Carolina; Cape Canaveral, Florida; Fort Lewis, Washington; and Hill Air Force Base, Utah. The work done at these sites involved groundwater sampling of multilevel samplers, flux pump tests, installation of multi-level samplers and wells, core sampling (including microbial core sampling techniques), partitioning tracer tests, and DNAPL controlled-release techniques.

Since 2004, Mr. Lee has been working on the scanning electron microscope to identify diatom; arsenic, chromium, and precipitate identification in sediment; and iron filing samples in a permeable reactive barrier (PRB) with secondary/backscatter detectors and EDX (X-ray) elemental mapping software. The identification of elemental weight percent, atomic percent, and the mapped location of the element in the region of interest can be achieved with the EDX detector/software.

Mr. Lee is also working on solid-phase characterization with Dr. Rick Wilkin at various field sites, such as Elizabeth City, North Carolina; East Helena, Montana; Ponchatoula, Louisiana; and the Cimarron Pork field site near Stillwater, Oklahoma. Mr. Lee operates the XRD, TGAMS and the atomic force microscope for his research. He has extensive experience in the collection of groundwater, lagoon, and soil core sampling techniques at concentrated animal feeding operations and PRB field locations.

Mr. Lee is the Alternate Radiation Safety Officer at the Kerr Center, where he helps to ensure a safe and compliant radioactive licensing program.
