Evaluations of the effects of the Columbia River on the unconfined aquifer beneath the 1301-N Liquid Waste Disposal Facility
Description: Westinghouse Hanford Company (WHC) requested that Pacific Northwest Laboratory (PNL) perform a study to determine what influence the Columbia River has on the aquifer beneath the 1301-N Liquid Waste Disposal Facility (LWDF) located in the 100-N Area. Because of the change in operational status of the N Reactor to dry layup'' in November 1989, there has been a reduction in the liquid effluent discharge to the ground in the 100-N Area. This reduction in discharge reduces the artificial recharge to the unconfined aquifer, thereby altering ground-water flow in the vicinity of the 1301-N LWDF. This study addresses these changes and evaluates the effect that the Columbia River has on the unconfined aquifer beneath the 1301-N facility under present ground-water conditions. 30 refs., 8 figs., 4 tabs.
