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
ORIN successfully reduced BTEX contaminated groundwater utilizing in-situ DPT injection of BAM combined with a slow-release oxidizer. Approximately 100 gallons of treatment chemistry was injected into each of 9 injection points at depth-specific intervals. The injection points were spaced to target the remnant hot spot area of a contaminant plume. The treatment chemistry injection
ORIN successfully conducted a pilot test to treat groundwater contaminated with GRO, DRO, Crude Oil, and PVOC utilizing BAM, a pyrolized cellulosic material, VB591 nutrient blend. Two pilot areas were conducted: one with BAM alone (IW-3) and one with BAM mixed with nutrients (IW-2). DPT points were advanced around each well. The treatment chemistry
ORIN successfully treated Benzene contaminated groundwater utilizing ORIN’s patented Bioavailable Absorbent Media (BAM). ORIN utilized DPT in order to effectively cover the injection area around MW-1. A vacuum truck was utilized during chemical injection to remove highly contaminated groundwater and to provide hydraulic control. Eleven injection points received a combined total of 1,100 gallons
ORIN successfully treated BTEX contaminated groundwater utilizing ORIN’s patented Bioavailable Absorbent Media (BAM). The primary contaminant, Benzene, was prevalent in five of the primary monitoring wells on site. ORIN utilized DPT in order to pinpoint the targeted areas with higher Benzene concentrations. A vacuum truck was utilized during chemical injection to remove highly contaminated
ORIN successfully treated BTEX contaminated groundwater utilizing in-situ chemical oxidation. Approximately 70 gallons of catalyzed sodium persulfate at 18-percent solution was injected into each of the forty-two injection points at depth-specific intervals. Each interval received approximately 20-gallons of treatment chemistry. The injection points were spaced in a grid pattern to treat the contaminant plume.
ORIN successfully treated BTEX, MTBE, & Naphthalene contaminated plume with ex-situ chemical oxidation. An excavator was present to displace a certain area of soil down to depth. A portion of that soil was then placed back into the excavated hole while the treatment chemistry was being applied to the soil. The excavator would then
