Document Description
The proposed In Situ Thermal Remediation Work Plan for the remediation of volatile organic compounds (VOCs) in soil and groundwater at the Embee Facility. The remedial action would involve using heat to volatilize VOCs in soil (in situ) which are then captured in the gas phase using vapor extraction. Heating would be achieved through physical heating (conduction) of the soil using steam or direct heating (heater wells would apply a heat source directly to the soil and groundwater) or through electrical resistance heating (ERH) using an electrical, alternating current is passed through soil and the soils resistance generates heat along the path that the current travels. ERH is most effective at treating low permeability soils because the clays heat very efficiently, and the VOCs are boiled out of the low permeability zones.
