In 2005, ARS completed its largest project to-date at a DOD facility in Southwest Georgia. ARS was contracted to an international consulting company to provide groundwater remediation treatment that included the injection of more than 170,000 pounds of ZVI powder during a first phase and 133,000 gallons of 8% sodium permanganate during a second phase.

The first phase was completed in the summer and the second in late fall. Two field injection/drilling crews worked simultaneously at separate parts of the base. During the sodium permanganate injection phase, a mixing operation was set up onsite to dilute 40% solution to 8% for the injection operation. Sonic drilling rigs were utilized to advance injection tooling efficiently and as well as to minimize the generation of soil cuttings. The ZVI and permanganate were delivered via 40 injection points, some of which within high activity zones within the facility. The injections were conducted at depths as great as 160 feet into a weathered limestone/clay formation.

Technically, logistically and from a safety standpoint, this was a challenging project. Overall the project was completed on-budget and on schedule.
