Geosyntec Meets with ARTT for Technology Advancement Discussion
Geosyntec met with the Alternative Restoration Technology Team (ARTT) a Naval Facilities Engineering Command (NAVFAC) chartered workgroup established to promote the use of cost-effective, innovative technologies in the Navy's Installation Restoration (IR) program at Naval Air Station, Jacksonville, Florida.
The ARTT fosters partnerships, supports research and technical resources, and encourages participation in NAVFAC-wide efforts. As part of these efforts, Geosyntec employees, and David Gent (USACE ERDC) met with 24 members from ARTT and the Optimization Workgroup to introduce them to electrokinetic (EK) technologies and update them on the status of advancements in vapor intrusion (VI) technologies.
After a short introduction to the site by Mike Singletary (NAVFAC SE), Evan Cox (Ontario) presented Geosyntec's EK-BIO™ and EK-TAP™ technologies. Next, Dave Reynolds (Ontario) and Rachel Klinger (Florida) led a presentation about Geosyntec's enhanced in situ bioremediation (EISB) project involving emulsified vegetable oil and KB-1® in the sand aquifer in Operable Unit 3 (OU3). Following the presentation, James Wang (South Carolina) conducted a site tour of Geosyntec's Environmental Security Technology Certification Program (ESTCP) EK-BIO™ demonstration site in OU3.
Todd McAlary (Toronto) and Helen Dawson (Washington DC) presented the status of advancements in VI which promoted a very high degree of dialogue, discussions, and questions among the participants.
NAS Jacksonville is located on the west bank of the St. Johns River in Duval County, Florida. The contamination within OU3 is associated with a former dry cleaning facility, which was located in former Building 106. Tetrachloroethene (PCE) was released through occasional spills and leaks, resulting in contamination of the shallow aquifer. Site characterization results indicate that chlorinated volatile organic compound (CVOC) mass present in the clay layer beneath the shallow sand aquifer can potentially serve as a long-term source of contamination to the shallow aquifer. This clay layer beneath the shallow sand unit is the target for the EK-BIOTM technology demonstration.
