Conducted long-term microcosm tests to evaluate the biodegradation potential of BTEX constituents in shallow aquifer material in Oklahoma. The project was partially funded by the USEPA.

Conducted investigation of a solvent spill to delineate the extent of contamination in the drift and bedrock aquifer at an industrial facility in Illinois. The contamination originated from a release of both light non aqueous phase liquids (LNAPLs) and dense non-aqueous phase liquids (DNAPLs). Developed and implemented a remediation program involving the installation of an air-stripping treatment system with a 99% removal efficiency. Conducted microcosm studies to determine the biodegradation potential and instituted an in-situ biodegradation program. A sampling plan, a quality assurance project plan, and a site health and safety plan were developed in compliance with Illinois Environmental Protection Agency (IEPA) regulations. The project was partially funded by the state of Kansas and Kansas State University.

Conducted ex-situ bioremediation of hazardous wastes using land treatment techniques at RCRA facilities located at various sites in Oklahoma. Project tasks included installation of lysimeters to monitor the effectiveness of the treatment zone and to provide early detection of contaminant migration.

Directed the investigation of a fuel oil spill at a large utility company in Kansas. Developed interim remedial methods for recovery of free-floating petroleum products and conducted detailed investigation to assess the extent and migration of contaminant plumes. Utilized soil gas investigation as a tool to provide quick and cost effective service in the delineation of the contaminant plumes. Conducted microcosm tests to assess the biodegradation potential of the soil and ground water contaminated with petroleum and chemical constituents. Developed methods to implement in-situ biodegradation of contaminants in the drift aquifer at sites owned by large utility and industrial facilities.
