~ G <br />' A aC1EMECN, ING, Cmry~ny <br />Environmental Solutions & Management, loc., Lakewood, Colorado 1996 - 1998 <br />Owner and President <br />' Chlorinated Solvent Remedial Action: Developed scope of work and technical approach for <br />n:mediation of tetrachloroethene plume from manufacturing facility. Completed review of site <br />hydrogeologic wnditions and performed ground-water modeling to evaluate ground water capture <br />' scenarios. Evaluated prospective n-medial measures including in-situ dehalogenation using passive <br />reaction wall technology. <br />Regulatory Review / IJtlgatlon Support: Pmvided analysis of applicable regulations (newly- <br />'. promulgated military munitions nile under RCRA) for small arms shooting range in anticipation of legal <br />action. Perforated cost/brnefit analysis of prospective remedial actions, <br />LJ <br /> <br /> <br /> <br />1 <br /> <br />1 <br />Environmental Assessment: Performed environnrrntal assessments for real esbte transactions. <br />Parsons Engineeriug Science, Inc., Denver, Colorado <br />Senior Hydrogeologist <br />1993-1995 <br />In~itu Bioremediatlon of Chlorinated Solvent: Project marrager for the investigation of the potrntial <br />for in-situ bioremediation of fuels and chlorinated solvents at the Rocky Flats Environmrntal Technology <br />Site (BEETS). A facility-wide survey was conducted to identify candidate sites suitable for evaluating & <br />demonstrating the potential for in-situ bion;mediation. Upon review of the darn, the Fast Trenches, OU- <br />2, was selected for lire study because of the presence of an appropriate substrate (cutting oils and other <br />aliphatic hydrocarbons), generally low dissolved oxygen levels, and the presence of chlorinated solvents <br />with attendant degradation by-products. A Work Plan was developed and implemented to obtain <br />geochemiral data of sufficient quality to demonstrate that naturally-occurring microorganisms were <br />currently degrading site contaminants. <br />Solar Ponds (OU-4) Closure: Team member developing the Phase I and the Interim MeasuresMterim <br />Remedial Action Decision Document (IIvl/LRA DD) for OU4, the Solar Evaporation Ponds, at the <br />RFETS. Tasks included evaluating field and laboratory analytical data to assess the nature and extent of <br />contaminated media beneath ponds liners. Analysis was used for evaluating remedial alternatives and <br />developing asite-specific baseline risk assessment Upon analysis of existing data, the Phase II RCRA <br />Facility Investigation/Remedial Investigation (RFI/RI) Work Plan for OU4, was developed and <br />implemented to better define extent of contaminated media. <br />' Environmental Engineering & Services, loc., Denver, Colorado 1992-1993 <br />Geological Engineer <br />' RCRA Closure Plans: Provided technical review and recommendations to gain agency approval of <br />RCRA Closure Plans for seven hazardous waste sites at the U.S. Coast Guazd Support Center in Kodiak, <br />Alaska. <br />Hydrogeologic Investigation of Chemical Release: Developed technical approach and scope of work <br />for the subsurface investigation of a toluene release at a chemical plant in Texas. <br />' Euvironmental Assessment: Conducted Phase I and Phase II environmental assessments to identify <br />potential sources of hazardous substances for Environmental Assessments (Eas) and Environmrntal <br />Impact Statements (E1Ss) required under the National Environmental Policy Act (NEPA) for highway <br />' and railway expansion projects that receive federal funding. <br />1 <br />t <br />
