Project Description:

In this demonstration project conducted for the Air Force Center for Environmental Excellence (AFCEE) at Cape Canaveral Air Station in Florida, the following procedures and techniques were used to install a Permeable Reactive Treatment (PeRT) system with dimension of 50 feet long by 40 feet deep by 4 inches wide. There were also three walls 9 feet long by 40 feet deep by 4 inches wide installed down-gradient of the large wall to evaluate the multiple treatment effects of several systems.
Foremost's in situ X-PeRT System, which is permeable to groundwater but reactive to the compounds of concern that are destroyed or trapped as they move through the engineered system, was installed to treat chlorinated compounds from previous releases at the site. Compounds of concern were TCE, DCE, and vinyl chloride. The X-PeRT wall, which was 50 feet below ground surface, was installed in 8 days by a jetted I-beam and continuous jet grouting techniques. The walls were installed to design by pounding in and pulling out a jetted I-beam with simultaneous injection of 120 tons of zero-valent iron filing slurry at a cost of $190,000. Total project cost for design, oversight and installation was $250,000. After it had been in place for about six months, DCE concentrations were remediated from 190 parts per million (ppm) up-gradient to less than 10 ppm down-gradient of the treatment wall.
This X-PeRT wall was the first of its kind and performed more efficiently than other systems tested. However, Foremost has not used the method again because BioLuxing has proven more efficient and easier and safer to install.
