General Information
Event Name: Monthly Engineering Forum Virtual Training
Topic: Paradigm Shift in Liability Management - Using HRSC and 3D Modeling to Develop a New CSM and Bring a Site to No Further Action Status
Hosted By: U.S. EPA
Office of Superfund Remediation and Technology Innovation
Event Description:

The Engineering Forum (EF), established in the late 1980s, is a group of engineers and scientists that supports the Superfund and RCRA programs in each of the ten EPA Regional Offices. As one of the EPA Technical Support Project’s (TSP) three technical forums, the EF is a medium for exchanging technical information regarding innovative site cleanup and characterization technologies. Monthly technical talks focus on site-specific engineering problems encountered, alternatives and solutions, and lessons learned. After each presentation, information regarding upcoming events and training are discussed and time for an Open Mic discussion is provided. If you are a Superfund, Resource Conservation and Recovery Act (RCRA), Brownfields, state or federal environmental professional who is interested in solving technical issues, register for any technical talks listed below that interest you and join the discussion!

Presentations are specifically designed for EPA staff including RPMs, OSCs, Corrective Action Managers, Superfund and Technology Liaisons, Chemists, Biologists, Physical Scientists, and Engineers from within EPA regions, program offices, laboratory system, and headquarters personnel as well as environmental professionals from state agencies, tribes, the U.S. Army Corps of Engineers, U.S. Dept. of Energy, and other federal agencies of all experience levels. THIS TRAINING IS NOT OPEN TO ACADEMIA, CONTRACTORS, CONSULTANTS OR OTHER PRIVATE ENTITIES.

We will try to meet any special accommodations necessary for our participants as possible if given a minimum of two weeks notice. You will be prompted to indicate if you need any special accommodations upon registering for these events.

*This training is offered free of charge to all registrants who are confirmed to attend. One CLP will be issued for each session attended when you register and log on with the registration link provided to enable your attendance to be confirmed.*

Additional Information:

An underground refined petroleum products pipeline developed a leak that resulted in pooled petroleum at the surface. Five remedial technologies were applied over a 13-year period. A significant rebound occurred at the conclusion of each remedial technology. A new Conceptual Site Model (CSM) was developed incorporating High Resolution Site Characterization (HRSC) and 3D contaminant modeling. This study revealed hydrocarbon pockets were serving as secondary sources leaching to groundwater resulting in chronic post-remedial rebound. A revised remediation plan was created to focus on eliminating all secondary sources in the vadose zone before remediating the dissolved phase contaminants. By eliminating the ongoing secondary sources prior to dissolved phase remediation, contaminant reduction efficiencies were drastically improved. Once Benzene and TPH groundwater concentrations were reduced below their regulatory goals, the presiding Judge agreed with the regulator’s recommendation and issued No Further Action Status. Join the Engineering Forum call to hear from Janet Castle, President and Founder of Eagle Synergistic Optimizing Technologies, and learn more about the HRSC tools used for this case study.
