In Situ Benzene Naphthalene

ORIN successfully reduced concentrations of benzene and naphthalene in groundwater utilizing in-situ chemical oxidation. The treatment area was approximately 1,800 square feet and the contamination was due to leakage from underground storage tanks (USTs) that were removed in 1996. The client elected to implement DPT injection of a peroxide-based reagent to reduce COC concentrations in groundwater to meet the Alabama Department of Environmental Management (ADEM) preliminary screening values (PSV). Two wells had concentrations of Benzene and Naphthalene above the PSVs. Fenton’s reagent effectively oxidized contaminants within the matrix. Forty six points received a combined total of 9,576 gallons of treatment chemistry.
