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 screened interval of 15 to 35 ft bgs were used to deliver the treatment chemistry. A total of approximately 86,430 gallons of treatment chemistry was injected across the site.
