Abstract
This decision document presents the selected interim remedial actions for portions of the USDOE Hanford 100 Area, Hanford Site, Benton County, Washington. The selected remedy is an interim action that involves removing hexavalent chromium from groundwater that discharges into the Columbia River. To intercept the chromium plumes, groundwater will be pumped from approximately 30 wells located along and inland from the river shoreline. The water will then be treated using an ion exchange treatment technology to remove chromium. The treated effluent will then be returned to the aquifer using injection wells located upgradient of the existing chromium plumes. The interim action includes monitoring of the groundwater near the river and the effluent from the treatment system to determine system performance in meeting the remedial action objectives for protection of the Columbia River. The interim action also involves institutional controls to protect human health from groundwater contaminants.
