Treatability Study: Using Various Oxidizers for TCE, PCE

ORIN sought to compare the effectiveness of sodium permanganate and sodium persulfate treatment chemistries on TCE and PCE contaminated soil.
Total oxidant demand testing for both persulfate and permanganate were performed with site soils.  Oxidant consumption […]

Remediation: Three rounds of injection completed

ORIN completes first of three rounds of injection for pilot testing of extract and re-inject process to create an oxidizing barrier to intercept the groundwater plume.  Project implantation is being conducted to test the treatment […]

Free Product Removal: Another successful free product removal

ORIN completes another successful free product removal project.  Utilizing oxidant injection and vacuum extraction ORIN was able to remove the NAPL free product and treat dissolve phase contaminants.  The project was implemented over a 2 […]

Ex-Situ Remediation of Former Gas Station UST Release

ORIN successfully treated petroleum contaminated soil and groundwater with ex-situ chemical oxidation during a pilot study at a former gas station facility. Petroleum hydrocarbons were reduced from 264,700 ppb to less than 10,635 ppb over a two-week period. ORIN’s […]

Chlorinated and Petroleum UST Release

ORIN successfully implemented a pilot study combining in-situ and exsitu chemical oxidation to treat contaminated soil and groundwater at a manufacturing facility. Chlorinated hydrocarbons were the remedial drivers. However, during the tank pull and subsequent ex-situ remediation, a large quantity of petroleum hydrocarbons was also present. […]

Ex-Situ Remediation of an Active Manufacturing Plant

ORIN successfully treated a 600 cubic yard petroleum and chlorinated hydrocarbon contaminated plume with ex-situ chemical oxidation. Petroleum hydrocarbons were reduced from 295ppm to less than 4.4 ppm and chlorinated hydrocarbons were reduced from 200 ppm to non-detect. ORIN’s approach […]

Ex-Situ Remediation of Former Wood Frame Manufacturing Plant

ORIN successfully treated unsaturated soils contaminated with creosote compounds including pentachlorophenol (PCP) and diesel range organics (DRO) using ex-situ chemical oxidation at a former wood frame manufacturing facility located in Lester Prairie, Minnesota. Two different treatment chemistries were implemented due […]

Ex-Situ Remediation of a Manufacturing Plant Drainage Lagoon

ORIN successfully treated a 5,920 cubic yard drainage lagoon with an oxidizing chemistry. Numerous contaminant levels were reduced to levels to meet U.S. EPA Toxicity Characteristic Leaching Procedure (TCLP) criteria and waste disposal facility limits. ORIN’s approach saved the client approximately $2,000,000 […]

Oil Refinery Pipeline Release

ORIN successfully treated petroleum contaminated groundwater with an enhanced bioremediation chemistry. Contaminant levels were reduced from 4,700 ug/L to less than detection over a four-month period. ORIN’s approach saved the client approximately $28K to $50K over traditional remediation approaches.
Site Characteristics:

Geology […]

Active Truck Terminal Release

ORIN successfully implemented a pilot study utilizing in-situ chemical oxidation to treat contaminated groundwater at an active truck terminal. Petroleum hydrocarbons were the remedial drivers. Due to the large amount of free phase diesel, ORIN recommended a remedial strategy combining […]
