A product release at a remote pipeline site was determined to contain naphthalene concentrations at a level that prompted remediation. Unfortunately, the area of the plume requiring attention was located in a forested area that rendered conventional remediation techniques such as excavation, soil vapor extraction (SVE) or groundwater pump and treat systems impractical. A recently developed in-situ oxidation process was employed as the best candidate technology to address the problem. The BIOX? Process proved to be a very effective remedial tool. The hand-held jet probe drilling technique used to place the oxidation reagent, eliminated the needed for direct-push equipment at the injection points. And, the mixer/pump trailer was parked over three hundred feet away at a spot convenient for efficient operation. The application resulted in a No Further Action (NFA) letter being issued by the State of South Carolina.
