LNAPL

ORIN successfully implemented Free Product Removal (FPR) in-situ chemical oxidation using catalyzed sodium persulfate to treat LNAPL, contaminated soil, and groundwater. Treatment chemistry was injected while the Geoprobe rods were raised throughout the target interval. A vac truck was present to remove LNAPL and desorbed contaminants while providing hydraulic control. Approximately 2,400 gallons of

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

ORIN successfully reduced the amount of LNAPL within the groundwater utilizing a combination of in situ chemical oxidation and vacuum extraction. Approximately four vacuum extraction events took place prior to the full scale injection event. A vacuum extraction truck was onsite and was utilized simultaneous to the injection event. 122 injection wells with a
