Remediation of Gasoline with Air Sparge and SVE
About:
A major petroleum retailer retained RCC to investigate and remediate a retail gasoline service station in Lindenwold, NJ. Gasoline constituents BTEX, MTBE and TBA were present in soil and groundwater above NJDEP Remediation Criteria with MTBE concentrations as high as 140,000ug/L.
RCC designed and constructed an air sparge, soil vapor extraction and groundwater recovery and recirculation remediation system to address the soil and groundwater contamination.
The remedial system operated for three (3) years. Following remedial action at the site, contaminants detected in groundwater were determined to be below the applicable NJDEP (Class IIA) groundwater remediation standards. An Unconditional RAO for soil and groundwater has been issued for the Area of Concern by an RCC LSRP.
