After implementation of the South-to-North Water Diversion Project which has attracted worldwide attentions, new surface water sources would be added and, accordingly, mining of groundwater for industrial and living water would be reduced to ease the mining pressure of the underground water and abate the decline of the water level in the depression centers of Shijiazhuang and the whole intake area. Numerical model was established in this paper to respectively calculate the underground water level in 2020 based on three schemes including mining status of underground water, urban water resource planning of South-to- North water diversion in Shijiazhuang and Hutuo River infiltration with artificial regulation and storage. It is estimated that after implementation of the South-to-North Water Diversion Project, the buried depth of groundwater of depression centers in Shijiazhuang in 2020 will increase by 28.5~41.09 m comparing with that without water supply through South-to-North water diversion.

The underground water testing over the years has found that the total dissolved solids, total hardness, chloride, nitrate (calculated in N) and many other factors in the underground water in Shijiazhuang exceed the limits specified in Sanitary Standard for Drinking Water GB 5749-2006 and are distributed in a point source pattern. 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.
