Ex Situ Chlorinated Solvents AOTech ORIN successfully treated BTEX contaminated groundwater utilizing in-situ chemical oxidation. Previous vacuum extraction events were unsuccessful in achieving full clean-up of the contamination. The client elected to implement DPT injection to completely destroy the site COC. Sodium persulfate catalyzed with sodium hydroxide effectively oxidized contaminants within the matrix. In addition,
Ex Situ Chlorinated Solvents AOTech ORIN successfully treated highly contaminated unsaturated soils using an advanced oxidation treatment chemistry by applying it while simultaneously mixing the soils with an excavator. Approximately 4,498 cubic yards of soil were treated and removed from the site during treatment efforts. The treatment area was divided into 25ft by 25ft individual
In Situ Benzene Naphthalene ORIN successfully reduced concentrations of benzene and naphthalene in groundwater utilizing in-situ chemical oxidation. The treatment area was approximately 1,800 square feet and the contamination was due to leakage from underground storage tanks (USTs) that were removed in 1996. The client elected to implement DPT injection of a peroxide-based reagent to
Chlorinated Solvents – Bedrock ORIN successfully implemented in-situ chemical oxidation using sodium permanganate to treat contaminated groundwater. An average concentration of 10% NaMnO4 solution was injected at a rate of 1.5 to 6 gallons per minute. A total of 11,820 gallons of treatment chemical was injected throughout the targeted plume area. Ninety-one injection points were
Chlorinated Solvents – Bedrock ORIN successfully treated chlorinated VOC contaminated groundwater utilizing In-situ chemical oxidation. A pilot test was first conducted at the site to assess the feasibility and effectiveness of the approach and treatment chemistry. The injection wells were constructed of 2 inch PVC and nested to isolate specific treatment intervals targeting groundwater beginning
In Situ Soil Vinyl Chloride ORIN successfully treated contaminated unsaturated soils using BAM treatment material in conjunction with chemical oxidation while simultaneously mixing the soils with an excavator. Approximately 120 cubic yards of soil were homogenized with Fenton’s Reagent by direct spraying. Following the completion of the Fenton’s reaction, approximately 18 cubic yards of BAM
Ex-Situ Soil Mixing–Chlorinated Solvents & Metals ORIN successfully treated contaminated unsaturated soils using BAM treatment material in conjunction with chemical oxidation while simultaneously mixing soils with an excavator. Approximately 29yd3 of soil were first treated with Fenton’s Reagent. Following the completion of the Fenton’s reaction, approximately three cubic yards of BAM were applied to the
