Case Studies

Baytown Township Groundwater Contamination Superfund Site.

ORIN has begun work on the Baytown Township Groundwater Contamination Superfund Site. The project utilizes both sodium permanganate and emulsified oil in various areas of the site.

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 […]

Active Gas Station – Powder Springs, Georgia

ORIN successfully implemented in-situ chemical oxidation using catalyzed persulfate to treat contaminated groundwater at an active gas station in Powder Springs, GA. Gasoline and BTEX compounds were the remedial drivers. The site achieved closure status […]

Former UST Leakage

ORIN successfully treated petroleum contaminated soil and groundwater with an enhanced bioremediation chemistry. Unsaturated contaminant levels were reduced from 2,900 ug/L to less than detection over a four-month period. ORIN’s approach saved the client approximately $20K to $48K over traditional […]
