CAREER SUMMARY

I have many years of experience in the chemistry field, including years in the United States Government, also working as a sergeant in the US Army and especially as a chemist at the US Bureau of Mines and at the US Mint while using specialized knowledge of chemistry, geophysics and mining to solve problems. I developed and applied quality standards on various research projects including assessing potential risks associated with metals, chemicals and hazardous materials at landfills and other cleanup sites throughout the western US. I also prepared reports and used EPA methods to characterize hazardous chemicals and their effects on water air and soil. I wrote the chemical hygiene plan for the Mint and the Bureau of Mines. In my last job at the US Mint in Denver, I helped the Environmental Engineer ensure the Mint was in compliance with EPA and City of Denver Wastewater regulations. I applied quality control methods and trained personnel in statistical processing of data and use of chemicals and disposal of hazardous chemicals properly. I have expanded my computer skills and am familiar with Word, Excel, PageMaker, PeopleSoft, Datamyte, and other chemistry applications of software such as XRF, UV, NMR HPLC and IR.

Responsible for assay determinations and analytical data to maintain specifications within the minting process. I solved chemical problems using specialized instrumentation such as X-Ray Fluorescence, spectrometers, Atomic Absorption Spectrometry to analyze wastewater, steel, copper plated zinc and other materials in order to meet contract specifications and compliance. I set up, maintained and wrote programs for the Datamyte Statistical Data System and trained the operators. I worked in the quality assurance sections helping inspect articles for compliance with physical characteristics such as diameter, hardness, edge thickness, upset diameter and metal defects. I set up and used the X-Ray Fluorescence Spectrometer and Carbon- Sulfur Analyzer for die steel and tool stee l machinability and durability. I used AA and other methods to analyze wastewater to insure the Denver Mint’s compliance with the EPA and City of Denver Wastewater Regulations. I also analyzed samples for chemical and biological oxygen demand.

I characterized minerals, rocks, uranium samples and other analyses as required. I wrote project proposals, monthly reports and papers on results obtained while working underground in metal and non-metal mines at many sites. I served as the Chemical Safety Officer, teaching Hazard Communication Training for the Research Center. I tested novel rock mass grouting materials applicable for acid mine drainage control and encapsulation of hazardous substances. I won a R&D 100 Award for a Coal Air-Lift Hydrohoist project for new methods of coal movement. I used EPA methods to provide guidelines for air, water and soil contamination at a uranium mine at Welpinit, WA for the Bureau of Indian Affairs. I characterized gold mine sites in Nevada and Arizona for gold leaching projects using novel lixiviants. I conducted tracer studies to characterize hydro geologic conditions at Idaho Springs, CO and Buena Vista, CO. I have helped in planning, performance and analyses of many types of compounds using specialized techniques including HPLC, IR, UV, NMR and Mass spectrometry. I designed and implemented changes to the coal screw auger system on the Coal Air-Lift Hydrohoist project to enhance production and our project won an R & D 100 Award in Chicago, Illinois. At Avondale, Maryland, I analyzed boiler and cooling water samples by prescribed procedures using wet chemistry methods, colorimeters, spectrometers, turbidimeters, and UV to characterize the condition of the boilers and cooling towers.
