Site Summary

ORC Advanced releases a maximum of 17% by weight of oxygen into a saturated area. Such a high release of oxygen can effectively reduce high concentrations of contaminants, allowing for successful bioremediation of source areas. A petroleum contaminated site in Virginia had TPH and MTBE contamination at levels much higher than MCLs. The source area contained concentrations of TPH and MTBE at 192,000 ug/L and 12,400 ug/L, respectively. A pilot scale application of ORC Advanced was initially designed to treat low levels of contamination at the site , approximately 20,000 ug/L of TPH. After injection was complete, it was found that concentrations were approximately 10 times higher than anticipated. This case study provides performance data in treating an unexpected high level of contamination with a low dose of ORC Advanced.
