AB: Optimal remediation design using the pump and treat method is obtained for a hypothetical contaminant transport with natural attenuation represented by first-order decay and sorption. The total pumping volume is set to the decision value. Simulation-optimization method is used to minimize the total volume and find optimal pumping locations. When the first-order decay rate becomes higher, less pumping volume is required but the pumping wells stay at the same positions. The location of pumping wells is on the centerline of domain and down-gradient region from highly contaminated zone. First-order decay rate has influence on the portion of the pumping rate; the lower decay rate causes the higher pumping rate is to be assigned. The sorption also influences on the optimal design. More pumping rate and pumping wells are required when the sorption effect increases. Most of additional wells are located on highly contaminated zone.
