Numerical Analysis of Solute Transport in Groundwater of Jingquan Water Source Area

At present, groundwater pollution is becoming more and more serious. In order to explore the groundwater pollutant migration in Jingquan water source area, this paper takes Jingquan water source area as the research area, and uses MODPATH to conduct trace simulation to show the particle migration path in groundwater flow, and carries out numerical analysis of groundwater solute migration in Jingquan water source area. The research shows: Several point pollution sources are set in the upstream of Jingquan water source, and the pollutants will continue to spread in the southwest direction. In about 100 days, the pollutants released at about 150 m away from the mining well will reach the water source, and in about 1000 days, the pollutants will almost reach the water source. In this study area, permeability is the main factor affecting the transport of pollutants, and the influence of dispersion on the transport of pollutants is relatively weak under the same permeability conditions.
