Successful treatment of petroleum contaminated soil and groundwater at the site of a former leaking underground storage tank using PermeOx®.
Benzene, Toluene, Ethylbenzene and Xylene
Former underground storage tank leakage
Orin Remediation Technologies
BTEX compounds including benzene, toluene, ethylbenzene and xylene were present in the site of a former leaking underground storage tank. PermeOx® was used to treat 41,200-square-foot plume of petroleum contaminated soil and groundwater.
Three months following the injection, benzene concentrations were reduced from 1,400 μg/L to 1.8 μg/L in the highest impact soils within the plume. Down and side gradient groundwater also showed significant reduction. Overall, unsaturated contaminant levels were reduced from 2,900 μg/L to less than detection over a four-month period.
ORIN successfully remediated the site by injecting Klozur® (sodium persulfate) and PermeOx® Plus chemistry through a series of direct push points over a five-day period.
