Interlayer oxidized zone and argillite-sisandstone-argillite sequence occur in red clastic rock formation with ideal artesian and circulating system of ground water.
Abstract: In the paper, by integrative using GIS and Geostatistics, we analyzed the special distribution characteristic of groundwater downrange in arid area.
We propose that As anomalism in groundwater possibly resulted from the combined effects of organic matter-enriched lacustrine sediments, geological setting and topographical characteristics.
Based on the quality data of overyear water table and groundwater, the research studied the dynamic variation of water table and quality of groundwater.
The karst depression belongs to the accumulative area of surface water and subdrainage area of subsurface water, the karstification is relatively week, and reservoirs are undeveloped.
Overpumping groundwater for drinking water and irrigation has caused water levels to decline by tens of metres in many regions, forcing people to use low-quality water for drinking.
The resistance to float relates to the attributes and conditions of the ground water, the pressure and floatage of water, the change of water level and the sudden supplement of water.
