Enhanced Biological Degradation Groundwater Remediation Project60 Minute Cleaners – College Parkway, Fort Myers, Lee County, Florida

摘要

A soil and groundwater remediation system was designed and installed at the 60Minute Cleaners in Ft. Myers Florida under the State of Florida Drycleaning SolventCleanup Program (DSCP) in March 2003. A contamination assessment wascompleted at the facility which showed chlorinated solvents concentrations,associated with drycleaning operations, exceeding soil and groundwater cleanuptarget levels beneath the facility with a groundwater plume migrating approximately200 feet downgradient of the facility.A remedial system was designed and implemented which included a soil vaporextraction (SVE) system to address affected soil. To address affected groundwater,nested groundwater extraction wells were installed downgradient of the drycleaningfacility and multiple injection wells installed upgradient of the facility. The primaryobjectives for installation and operation of the remediation system were:1. Enhance the rate of dechlorination of dissolved chlorinated ethenes withindigenous microorganisms in the presumed source area (beneath the former
