Knowledge of groundwater-flow patterns \nand rates is essential for effective management of groundwater resources and for mitigation of potential \nadverse effects of the plumes on drinking-water supplies and on ecosystems. Eight hypothetical remedial \nscenarios were evaluated to hydraulically contain a VOC plume.  Specifically, the remedial scenarios \nwere optimized to achieve full containment by altering the pumping well locations, adjusting the pumping \nrates, and adjusting the discharge locations and rates.  This modeling analysis will allow the New York \nState Department of Environmental Conservation (NYSDEC) to evaluate pump-and-treat remedial \nalternatives identified in a separate feasibility study (FS), including plume containment and hydrologic \neffects. Modeling will also provide insight into the potential impact to the environment that remedial \nalternatives may have.
