POLLUTANT SOURCE DETECTION OF GROUND WATER CONTAMINATED BY CHLORINATED ORGANIC COMPOUNDS USING GENETIC ALGORITHM

Abstract

It is important for recovering the ground water contaminated by chlorinated organic compounds to search the point of pollutant source. The authors study the methods to detect the point of pollutant source by GA (genetic algorithm) using existing concentration data obtained from monitoring wells. We assume that pollution proceeds by advection and diffusion in two-dimensionally without absorption. Unknown factors detected are a source point, the direction and the velocity of ground water, the concentration of source point, the beginning time of pollution and the continued period of pollution. The method proposed is verified by the virtual numerical simulation and is applied to the actual polluted site.
