Abstract: For the remediation of aqueous phase plumes extending over large areas simulation models are often used to predict the response of the aquifer system and the contaminant concentrations to the remediation strategy. Models are used to understand the water balance and contaminant transport characteristics of a particular site, analyze the design of the remediation system with respect to placement of wells and their pumping rates and to evaluate the cost of remediation and the length of time required to clean the aquifer. In addition, models can be used to evaluate the longterm concentration profiles and risk exposures that will result from the remediation strategy. The purpose of this study is to calculate for a particular example aquifer the reliability of model predictions in the context of a pump and treat strategy.
