Senior Principal
Geosyntec Consultants

Mr. Whisman has over 26 years of experience supporting clients on more than 450 challenging remediation projects across the world. Much of his career has been working closely with client managers, technical organizations, and government agencies to develop effective and innovative technical solutions to challenging remediation projects. He has assisted many clients, including major oil & gas and energy sector clients, with the development of remediation guidance and engineering design standards. He has developed processes for making the right in-situ remediation technology decisions and has created remediation system optimization tools and guidance. He has developed patented chemical oxidation process, such as ozone and hydrogen peroxide injection techniques, created real-time feasibility study mobile platforms, and involves remote monitoring and optimization tools into most of his remediation designs. He has collaborated on many technical guidance documents, research, and trainings throughout his career for organizations such as ITRC, NGWA, and PERF.


PLATFORM PRESENTATION

Innovative Remediation Solutions to Aggressively Remediate LNAPL Plumes

Recent case studies will be presented to detail innovative remediation solutions at different and challenging LNAPL plumes. The first case study will show how the combination of many in-situ technologies and remote monitoring resulted in the aggressive remediation of a 10-acre LNAPL plume to residential standards in just 5-months of system operation at a Brownfields redevelopment site. Remediation technologies included oil recovery, groundwater recovery, air sparging, surfactant injection, vacuum-enhanced oil recovery, and enhanced bioremediation. The case study will demonstrate how the combination of aggressive in-situ technologies and remote control and data management features allowed for real-time system optimization and plume visualization to understand remediation progress. LNAPL mobility and risk assessment work led to the development of site-specific cleanup goals for the site (based on potential residential use). The project achieved “no further action” status following the 5-month remediation and continued monitoring. The system was able to be optimized remotely by the project engineer, and included real-time monitoring and adjustments, including groundwater elevations, and pressures and flow rates of remediation equipment. Variable frequency drives on electrical pump motors made it easy to remotely adjust flow rates and liquid levels of recovery trenches across the site. Another case study involved the remediation of a long-term oil spill into the ocean from an on-shore industrial area in the Bahamas. The case study will demonstrate how an innovative 3-stage barrier system along the ocean was effective to prevent oil migration. Thousands of gallons of oil had been migrating into the ocean each week prior to the innovative 3-stage barrier system, which included a 1600’ steel barrier wall into the ocean floor, a 9-segment oil recovery trench system (over 1500’ long), and an HDPE liner barrier system. A third case study will include an innovative “enhanced” landfarming operations to treat over 40,000 cubic yards of crude oil impacted soil. The presentation will discuss various remediation system optimization concepts that can be included in any remediation system design and O&M program to reduce months, or perhaps years, off of the typical remediation duration. The presenter has over 26 years of experience designing remediation systems and has been involved in over 450 remediation projects in his career.
