Case Studies - NJ003 - Ferox^sm

Ferox^sm was successfully applied in the vadose zone at a site located in Newark, New Jersey. The geology at this active industrial facility consists primarily of fine- to coarse-grained sand with approximately 15-20% fines. Approximately 1,500 cu.yd of TCE- and PCE-contaminated soils lie underneath 6 inches of concrete.

Outcome

Subsequent to injection iron powder was detected at a radial distance of more than 9 feet from the injection point during. Average total iron content within the soil matrix increased by 170%. The iron powder was injected within a six (6) foot vertical thickness in the vadose zone.

Post-injection samples collected from within the Ferox^sm application zone indicated PCE and TCE reductions as high as 86 and 98 percent, respectively. These reductions were achieved within the 3.5 month remediation period without the accumulation of daughter products associated with PCE and TCE degradation. The reduction patern had a strong correlation with the iron distribution.
