Non-Point Source Contamination of Aquifers

Part of: Optimizing the Resources for Water Management

Abstract: The paper discusses a new method for simulating the movement of contaminants from a diffuse source at the soil surface through a variably-saturated porous medium. The method accounts for the effect that the distribution of the soil water velocity and soil properties have on the resulting contaminant concentration in the soil profile, so that an accurate prediction of the arrival time of a contaminant plume at the water table of an aquifer can be determined. The objective is accomplished by using a statistical approach to simulate the movement of a contaminant through a porous medium.
