Optimal design of cleanup schemes for groundwater polluted by multiple contaminants Yanyong Xiang, J.F. Sykes, N.R. Thomson Department of Civil Engineering, University of Waterloo, CWono, Canada #21 ABSTRACT A formulation to design the optimal cleanup schemes for groundwater pol- luted by multiple contaminants of different characteristics is described. The objective function is a weighted sum of the volumes of the extracted and/or injected water. The groundwater quality constraints include, for each con- taminant, the pointwise and the spatially averaged residual concentrations. Various solutions to a hypothetical problem involving two contaminants of different characteristics and remediation requirements are presented. INTRODUCTION Pump-and-treat is one of the major technologies employed for the reme- diation of contaminated groundwater aquifer systems. For cases when the remediation is targeted at a single contaminant, several formulations have been proposed to c
