Study Of Water Quality Evaluation And Prediction Of The Shallow Groundwater In Fuxin

According to the investigation of Fuxin shallow groundwater, adopting the single constitute composition evaluation combining with the comprehensive evaluation method, the water quality condition of 51 groundwater wells and 19 underground headwaters was evaluated in this paper, which disperse over Fuxin downtown, suburb, Fuxin county and Zhangwu county. The groundwater evaluation results were geographically analyzed on map by MapInfo Professional software, and the fluoride content of Fuxin groundwater had been made special subject map. Take the Wangyingzi mineral area underground headwaters as an example, the groundwater flow model was established by Visual MODFLOW software to predict the changing of groundwater level in studying area in 20 years .The studying results indicate that water resource in Fuxin is grave shortage. Especially, shallow groundwater is gravely contaminated whose main contamination factors are fluoride, iron, manganese and total hardness etc, that GIS as graphic tool of environmental quality appraises, enables to make data analysis and forecasts of pollution change more convenience, and that groundwater level in studying area declines obviously, and probably form the gigantic descending funnel in 20 years. It is suggested to enlarge treatment and reuse degree of waste sewage, to improve utilization efficiency of water resources, to decrease exploiting amounts appropriately, and to adjust groundwater exploiting layout.
