Ex-Situ Remediation of Former Gas Station UST Release

|0 Comments

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 approach saved the client approximately $85K over traditional remediation approaches.
Site Characteristics:

Site: Former Gas Station near Central […]

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. ORIN’s approach saved the client approximately $65K over traditional remediation approaches.

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 saved the client approximately $125K over a traditional dig and haul approach.

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 to differing soil chemistries at the site. ORIN’s approach saved the client approximately $500,000 over traditional remediation approaches.

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 over a dig and haul approach.
Site Characteristics:

Site: Manufacturing plant near
Grand Rapids, Michigan
Geology: Clay and sand interface […]

Oil Refinery Pipeline Release

|0 Comments

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 – fine grained, silty, calcareous sand.
Groundwater velocity – variable (10-3 to 10-5 cm/sec)
Contaminants – 4,700 […]

Active Truck Terminal Release

|0 Comments

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 mechanical and chemical oxidation remedies. ORIN’s approach saved the client approximately $45K over traditional remediation approaches.
Site Characteristics:

Site: […]
