Abstract

Abstract Three well configurations were compared in terms of short-term ground-water contaminant plume containment. These include parallel, octagonal and combination systems. Each system had three extraction wells upgradient and three injection wells downgradient of the contaminant plume. For each system, optimal pumping values and resulting potentiometric surface smoothness were computed for a hypothetical plume. Tested models utilized linear programming optimization and simulation via the response matrix method. The octagonal well configuration required less pumping for a pumping period of 8 days, than did the parallel or combination systems. The octagonal configuration resulted in the smoothest potentiometric surface, in terms of difference in final head at observation wells compared with those at the contaminant source.
