Work Plan for a Treatability Study in Support of the Intrinsic Remediation (Natural Attenuation) Option at The Current Fire Training Area (Site FT-08) and The Christmas Tree Fire Training Area (Site FT-03)

摘要

This work plan, prepared by Parsons Engineering Science, Inc. (Parsons ES), formerly Engineering Science, Inc. (ES), presents the scope of work required for the collection of data necessary to conduct a treatability study (TS) for remediation of groundwater contaminated with petroleum hydrocarbons and solvents at Site FT-03, the Current Fire Training Area, and Site FT-03, Christmas Tree Fire Training Area, located at Westover Air Reserve Base (ARB) in Chicopee, Massachusetts (the Base). Several remedial options will be evaluated during the TS, including free-phase product removal (if present); groundwater extraction, treatment, and disposal (i.e., pump and treat); bio- sparging; and natural contaminant attenuation (intrinsic remediation) with long- term monitoring. All hydrogeologic and groundwater chemical data necessary to evaluate the various remedial options will be collected under this program; however, this work plan is oriented toward the collection of hydrogeologic data to be used as input into groundwater flow and solute transport models in support of intrinsic remediation for restoration of fuel-hydrocarbon and chlorinated solvent contaminated groundwater.
