Fracture Enhanced Dual Phase Soil Vapor Extraction

A former manufacturing facility in South-Central, Iowa was contaminated with trichloroethene (TCE) in the soil and groundwater. The soil, a tight highly consolidated clay, had significant amounts of TCE present requiring source removal down to a depth of 30 feet. Due to the soil’s low permeability and perched water table, a horizontal sand filled fracture enhanced dual phase SVE system in the vadose zone was selected for source removal.
