Migration of contaminant plumes in aquifer systems can be controlled by producing desired changes in local flow rates and hydraulic gradients through the use of pumping and recharge wells. Such management scenarios have been used in the past for controlled operations in main aquifers. It is also possible to describe similar control procedures for multilayer aquifer systems. In these applications the migration of contaminant plumes in one layer may be controlled through the use of pumping and recharge wells in other layers which control the hydraulic gradients in the contaminated aquifer. In such applications the contaminated aquifer will not be interfered with and hydraulic gradient control operations will be performed on adjacent aquifer layers avoiding direct contact with the contamination source. Such operations may prove useful in case of hazardous waste management. In the study discussed here, mathematical preliminaries of the models utilized in this type of an operation are reviewed, and the effects of management scenarios are discussed for a typical aquifer considering only the hydraulic control aspects of the management process. Management procedures which incorporate the contaminant transport process and operational cost optimization processes into the analysis are not the subject matter of this study.
