Ex-Situ Soil Mixing–Chlorinated Solvents

ORIN successfully treated contaminated unsaturated soils using BAM treatment material in conjunction with chemical oxidation while simultaneously mixing soils with an excavator. Approximately ten 80yd3 batches of soil were transferred to a treatment area where they were treated with Fenton’s Reagent. Following the completion of the Fenton’s reaction, approximately eight cubic yards of BAM

DPT Injection & Extraction – LNAPL

Corrosion of an oil water separator at an operating locomotive service building resulted in the release of LNAPL into the subsurface. ORIN successfully treated soil and groundwater utilizing a combination of in-situ chemical oxidation and vacuum extraction. Nine injection points were advanced to an injection interval of 15 to 10 ft bgs using Geoprobe

BAM Injection – Per- and polyfluoroalkyl substances (PFAS)

ORIN conducted a pilot test to treat groundwater contaminated with PFAS using BAM, a pyrolized cellulosic material. BAM was mixed with water and injected through 46 DPT points encompassing PZ-1 and MW-5. A total of 4,445 gallons of BAM solution was injected through the 46 points. During injection activities, BAM was observed in PZ-1.

Permanent Point Injection & Extraction – LNAPL Free Product

Leaks from underground storage tanks resulted in the release of LNAPL free product into the subsurface. The plume has since migrated across a busy road to a nearby residential area. ORIN successfully injected treatment chemistry into 7 drilled injection points on the gas station property and 13 points on residential properties. Approximately 10,000 gallons

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 the 4 and 6

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 injection to remove

Remediation: Catalyzed Hydrogen Peroxide Injection

ORIN had just traveled to southern Alabama to successfully reduce concentrations of benzene and naphthalene in groundwater utilizing in-situ chemical oxidation. The site is a former military base with a targeted treatment area of approximately 1,800 square feet. The client elected to implement DPT injection of a peroxide-based reagent to reduce COC concentrations in groundwater

Remediation: Another Successful Inject & Extract Project

ORIN has completed work at a former gas station in western Nebraska utilizing in-situ chemical oxidation with vacuum extraction. A dual phase extraction system was previously in place, but was not sufficient in meeting the site clean-up goals. The contaminants of concern at this site were benzene, toluene, ethylbenzene, and xylene (BTEX). The treatment chemistry

Remediation: A Successful Active Gas Station Implementation

ORIN returns from central Nebraska having completed in-situ chemical oxidation project at an active gas station.  The objective of this project was to eliminate dissolved phase benzene, toluene, ethylbenzene, and xylene (BTEX) compounds.  Activated sodium persulfate combined with calcium peroxide was chosen as the right treatment chemistry.  Delivery of the treatment chemistry was performed by

Remediation: Active Military Base in Puerto Rico

ORIN had the opportunity to travel to Ft. Buchanan near San Juan, Puerto Rico to conduct an Enhanced Reductive Dechlorination injection (ERD). The project was designed to treat contaminated groundwater affected with chlorinated solvents. A series of drilled injection wells and DPT injection points were utilized to deliver the electron donor, carbon substrate solution.
