This paper describes the application of linear programming to optimize the number, location, and rates of extraction/injection for a pump and treat system at a groundwater remediation site. The constraints of the system include minimization of offsite migration potential and adequate flushing of contaminated groundwater. The flow system was simulated using the MODFLOW model. The same finite-difference grid was used to identify model cells for location of injection/extraction and monitoring wells and for defining the objective function in terms of pumping costs for the linear programming formulation.
