Greg Bischof

Principal Scientist

Mr. Bischof is a Principal Scientist whose primary duty is the management and internal oversight of subsurface investigation / remediation sites.  He manages complex projects while providing technical support to project managers through document review and mentoring.  Mr. Bischof has 26 years of experience in environmental investigation and remediation at a variety of sites, including many petroleum sites.  This experience includes site specific cleanup/remediation planning, closure feasibility assessments, and negotiating access agreements and property transactions with property owners. He has significant regulatory expertise and regularly acts as the liaison between his clients and local, state and federal regulatory agencies.  Previously managed contract work for EPA Regions 7 & 5, and the Missouri Department of Natural Resources (MDNR). Experienced with managing sites in the Missouri Petroleum Storage Tank Insurance Fund (PSTIF).


Managed or provided senior oversight on over 150 MRBCA projects for a variety of commercial and industrial clients.  These projects involve site characterization, geotechnical and hydrogeologic testing, development of corrective action / risk-based cleanup plans, implementation of sampling / monitoring programs, performance of risk based assessments, statistical stability evaluation, and project estimation / budget tracking.

Experienced with the development and review of risk assessments and other related activities including but not limited to work plan development, corrective action plans, and regulatory coordination.

Designed and installed multiple remediation systems, supervised chemical oxidation projects, coordinated various free product recovery programs (systems), and managed large soil excavation projects.

Manages subsurface investigation and remediation projects in the MDNR Brownfields/Voluntary Cleanup Program (BVCP), including sites in the Drycleaning Environmental Response Trust Fund (DERT).

Key BVCP / DERT projects include the multi-zone characterization of Tetrachloroethylene (PCE) and petroleum based solvent releases at a former dry cleaning facility. Key tasks included hydraulic testing of a deep water well, installation and operation of an interim groundwater recovery system, performing a soil / vapor survey within a building complex, and completing a   3-D geophysical survey of the plume.

Managed and assisted with multiple railroad projects in Missouri and Alabama.  Railroad sites are highlighted by the investigation and recovery of released diesel fuel and used petroleum products at a major railroad facility.  Work was completed with no down time to the facility despite the collection of soil samples from over 70 locations and the excavation of 1,700 tons of impacted soil.  Installed and operated a fluid recovery system, and completed a risk assessment.
