Mr. Grigsby has designed, conducted, and evaluated large-scale subsurface drilling projects, soil- and groundwater-sampling programs, aquifer tests, and soil-gas sampling programs in support of environmental investigations, remediation projects, and water resources evaluations. He has conducted geologic, hydrogeologic, and geochemical evaluations at sites located throughout the United States and over a broad range of environments — from relatively simple alluvial settings to complex fractured bedrock regimes. He has been involved in projects addressing chlorinated solvents, PCBs, petroleum hydrocarbons, and metals.

Since late 2017, Mr. Grigsby has been SSP&A’s field project manager for a large demolition, remediation, and redevelopment project that has involved coordination with several contractors, the site owner, state regulators. Other recent work has involved the assessment of hydrologic and geochemical impacts of oil and natural gas development in the eastern and western U.S., RCRA cleanup investigation and planning, and environmental management for a commercial spring-water site. He has presented findings for several of these projects at public meetings and regulatory hearings.
