Risk Analysis Of Groundwater Pollution In Xi'an City

As the developing of the economy and society, Environmental problem began to emerge. Specifically in some developing countries, such as China. So the experts began to study how to control the endangering cause by environment pollution. To reduce the endangering, the experts advance the prevention of risk in environment. Groundwater is very important to people in production and live, it's a big wealth. In China,it's an integral part of water resources, and also an important source of agricultural, industrial and domestic water, it'can ensuring people with a normal daily life, support economic development and maintain the balance of nature. In the dry and semi-dry area, the groundwater play a key role. And now people more and more use groundwater that make the groundwater worse. The pollution has appeared in some areas. So it's important that forecasting the groundwater pollution. It's a hot spot issue of forecasting groundwater pollution both in China and abroad. In this paper, I gather lots of data with xi'an groundwater, determine a typical case for the object of study, and then use the GMS to simulate the pollution of ground water, study the migration of pollutant in groundwater, to do the early warning of groundwater.Xi'an Jiangcungou refuse landfill is the only refuse landfill in Xi'an. And now 90% refuse of xi'an are treated in there. Xi'an is a important city in northwest China, Industrial development and with high densities population. So, choose the Jiangcungou refuse landfill for the object of study. Evaluate the quality of groundwater according to the groundwater data with synthetic index. Then the conclusion is that the groundwater of Xi'an is good. On next step, analysis the impact of refuse landfill to the groundwater. In different years, rendering the simulated diagram of pollution.
