Starting by introducing the hydrological and geologic characteristics of Shijiazhuang, this paper analyzes the chemical properties and pollution status of the underground water in the city and the effect of factors that exceed the standard on the human body. Based on the analysis, it further discusses the causes for pollution and cases of pollution treatment that absorbed tremendous manpower and resources in the past and thus resulted in huge economic losses to the state. The paper concludes that it is extremely important to make a serious commitment to the pollution control. Judging from the hydrological conditions, the southeast part shows stronger anti-pollution performance than the northwest under the natural state.展开更多
