This decision document presents the selected interim remedial action (IRA) for the Modesto Ground Water Contamination Site in Modesto, Stanislaus County, California. The primary components of the selected remedy include groundwater extraction, groundwater treatment by air stripping with carbon adsorption, discharge of treated groundwater to the City of Modesto's water system, and soil vapor extraction (SVE) followed by carbon adsorption. The selected alternative is expected to remove a substantial portion of dissolved PCE from the groundwater. EPA will be monitoring the downgradient edge of the plume to determine if the remaining PCE would be removed through natural attenuation. If necessary to comply with discharge requirements, extracted groundwater will also be treated using an ion exchange unit to remove naturally occurring uranium.
