Modeling Remediation of a Polluted Aquifer in Israel

Abstract:

The Givon aquifer in Israel was heavily polluted with Perchlorate during tens of years. The sandy aquifer is made up from layers belonging to seven facies, the predominant one is being sand. Remediation is conducted by pumping out water from the upper part of the aquifer for treatment. As a first step, the aquifer is modeled as a stratified one in the neighborhood of a partially penetrating well. The thickness of the layers of different permeabilities is random, with univariate distribution determined from measurements in a few boreholes. Prediction is carried out depending on discharge water realizations of permeability distribution and pollutant spatial distribution.
