ORIN successfully reduced BTEX contaminated groundwater utilizing in-situ DPT injection of BAM combined with a slow-release oxidizer. Approximately 100 gallons of treatment chemistry was injected into each of 9 injection points at depth-specific intervals. The injection points were spaced to target the remnant hot spot area of a contaminant plume. The treatment chemistry injection was coordinated with vacuum extraction to control hydraulic activity more accurately and to improve injection efficiency. This facilitated preferred treatment chemistry coverage within the targeted treatment area.
