Mr. Adcock has a thorough knowledge of Industrial and Manufacturing facilities throughout the USA. He is responsible for the Industrial Division within GER. He is very experienced with Nuclear Power and its specialized environmental problems. As a (GS-12) Nuclear Engineer for the U.S. Naval Shipyard, he was responsible for the maintenance and repair of primary nuclear plant components, i.e., steam generators and main coolant piping. He directed a fast response team of mechanics, engineers and support personnel to undertake steam generator repairs within a moments notice throughout the world for the U.S. Navy. His responsibilities included development procedures, specifications, tooling design, and training to ensure the safety of the mechanics as well as the components. Radioactive materials and radiation exposure were of primary concern. Much of the repair was on highly contaminated and radioactive material; therefore, considerations were necessary to minimize risks.

Mr. Adcock is responsible for the Environmental Compliance & Industrial Division within GER. He has a thorough knowledge of Industrial and Manufacturing facilities throughout the USA. His experience includes a wide range of environmental issues regarding air, soil and water pollution. He is experienced with the development and implementation of UST/AST Management Programs including data gathering, risk assessment, remediation, prevention of future problems, and liaison with regulatory authorities to ensure compliance. He has directed engineering studies as necessary to perform detailed site characterization reports (SCRs), aboveground storage tank facility closure reports, risk assessments including the use of detailed computer modeling, waste minimization analysis, groundwater quality investigations, etc. He has also directed and conducted many Phase I Environmental Site Assessments, Phase II Environmental Site Assessments, Hazardous Waste Closure Plans, etc.

Mr. Barnhill has held key technical and managerial positions in the areas of environmental and geotechnical engineering. He had been an adjunct professor of engineering at Old Dominion University teaching foundation engineering for 11 years. He has been involved in over 6000 projects nationally and overseas, but predominantly located on the east coast from Maine to Florida. Projects have included DOD projects, such as the Pentagon Basement Renovation, commercial buildings, large industrial and waterfront facilities, coal terminals, landfills, roadways, bridges, slope stability, underwater slopes, bulkhead design, underwater retaining walls, foundations, soft soil response, ground reinforcement, and ground improvement. He has developed computer programming in various formats to analyze and evaluate several geotechnical issues. Recently, he has added finite element modeling to enhance company geotechnical abilities. Using the FE method, the company can now evaluate more complex problems that are difficult or impossible to do with conventional methods.

His environmental experience includes Phase I environmental assessments, Phase II contamination assessments, and Phase III contamination site characterization and risk assessments. He has performed groundwater monitoring, aquifer testing, and computer modeling to evaluate contaminant transport, closed loop groundwater remediation systems and 3D groundwater withdrawal using MODFLOW.
