Modelling the position of pumping well located between two parallel contaminant sources

Abstract

This article provides an analytical model to determine the suitable location of pumping well located between two polluted parallel sources. The first source is assumed to be a polluted river, while the second one is an arbitrary contaminant source such as landfill leachate site or wastewater. The location of the well is specified so that it gets the highest amount of river water that satisfies water quality requirements. To validate the model results, a numerical simulation is conducted using MODFLOW to calculate the concentration of contaminants at various locations determined by the proposed analytical model. The results confirmed the suitability of the analytical model to determine the location of pumping well. Additionally, it is found that any increase in pumping time, pumping rate or initial contaminant concentration increases the distance between river and well.
