Analysis of hydrochemical processes controlling the urban groundwater system in Seoul area, Korea

摘要: Urban activities cause a number of hydrogeological environmental problems. The aim this study was to undertake hydrochemical evaluation the urban aquifer system in Seoul, Korea. Well monitoring, analysis, identification contamination sources, and an assessment mechanisms impact were undertaken. quality is affected by several processes groundwater contamination. Hydraulic conductivity Seoul aquifer, geologically consisting alluvium, granite, metamorphic rocks, varies from 2.3×10−9 1.5×10−3 m/sec. Interpretation data indicates that pollution causes general decline baseline downgradient. Sliding stiff diagrams illustrate mixing effect between polluted water background fresh groundwater. Groundwater area diffuse industrial complexes, seepage oil storage tanks, infiltration sewage, leachate percolation abandoned landfills.
