"Most of the groundwater at the Cliffside site was apparently assumed to discharge into the Broad River (other than groundwater discharges to small streams such as Suck Creek) according to a generalized conceptual model (Legrand, 2004) before actual site-specific hydrogeologic data were analyzed," Cosler wrote in his report. "Statements to this effect were made at numerous points in the CSA and CAP reports. However, HDR did not present any site-specific data analyses or groundwater flow modeling that would support this assumption in either report. In fact, as discussed below, the boundary conditions for the CAP Parts 1 and 2 flow models effectively forced site groundwater to discharge into the river at the downgradient model boundary."
