DPT Injection – Chlorinated VOC’s

DPT Injection – Chlorinated VOC’s ORIN successfully treated chlorinated VOC’s contaminated soil and groundwater utilizing In-situ chemical bioremediation during the pilot scale injection. Twenty-six injection points were advanced using DPT throughout the area. A barrier wall injection was also implemented to intercept the advancing plume before migrating off-site. The vertical injection zone extended from an

In Situ BTEX

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

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

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 – Clay & Bedrock

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

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 BTEX

DPT Injection – Benzene ORIN successfully treated BTEX contaminated groundwater utilizing ORIN’s patented Bioavailable Absorbent Media (BAM). The primary contaminants, Benzene and Xylene, were prevalent in the two monitoring wells on site. ORIN utilized DPT in order to pinpoint the targeted areas with higher Benzene and Xylene concentrations. A vacuum truck was utilized during chemical

In Situ PCE

BAM Injection – Chlorinated Solvents ORIN successfully conducted two pilot tests to treat groundwater contaminated with chlorinated solvents using BAM, a pyrolized cellulosic material. BAM was mixed with water and injected through 4 and 6 DPT points encompassing MW-03 and MW-04 respectively. A total of 700 and 1,200 gallons of BAM solution was injected through
