An analysis of groundwater quality evolution in the area of depression cone in the Santan riverside wellfield

The hydrochmical characteristics and the spatial and temporal distribution of water chemistry in the shallow groundwater in the Lanzhou faulted-depression basin were examined in this paper. The study focused on the exploitation of groundwater in shallow groundwater areas and analyzed the relationship of the Yellow River for groundwater recharge and water quality of the exploitation of the evolution of the land funnel. A typical rift basin water monitoring data for many years (1987-2006) of groun...
