The WATEQ4F-based “multiple step method”, or the method of running WATEQ4F repeatedly, was used to evaluate the error propagation in computations of water-mineral interactions under the circumstances of constant and varied temperatures due to the uncertainties of input variables. The results show the following: the errors of water chemistry analysis can strongly affect the modelling results of water-mineral reactions; different input variables (errors) have different effects on the saturation indices (S.I.) of different minerals; in many cases, the S.I. errors of minerals change with temperatures.

Hundreds of precipitation samples collected from meteorological stations in the Ordos Basin from January 1988 to December 2005 were used to set up a local meteoric water line and to calculate weighted average isotopic compositions of modern precipitation. Oxygen and hydrogen isotopes, with averages of-7.8‰ and -53.0‰ for δ^18O and δD, respectively, are depleted in winter and rich in spring, and gradually decrease in summer and fall, illustrating that the seasonal effect is considerable. They also show that the isotopic difference between south portion and north portion of the Ordos Basin are not obvious, and the isotope in the middle portion is normally depleted. The isotope compositions of 32 samples collected from shallow groundwater （less than a depth of 150 m） in desert plateau range from -10.6‰ to -6.0‰ with an average of-8.4‰ for δ^18O and from -85‰ to -46‰ with an average of-63‰ for δD. Most of them are identical with modern precipitation. The isotope compositions of 22 middle and deep groundwaters （greater than a depth of 275 m） fall in ranges from -11.6‰ to -8.8‰ with an average of -10.2‰ for δ^18O and from -89‰ to -63‰ with an average of -76‰ for δD. The average values are significantly less than those of modern precipitation, illustrating that the middle and deep groundwaters were recharged at comparatively lower air temperatures. Primary analysis of ^14C shows that the recharge of the middle and deep groundwaters started at late Pleistocene. The isotopes of 13 lake water samples collected from eight lakes define a local evaporation trend, with a relatively flat slope of 3.77, and show that the lake waters were mainly fed by modern precipitation and shallow groundwater.

The Ordos Cretaceous Groundwater Basin, located in an arid-semiarid area in northwestern China, is a large-style groundwater basin. SO4^2- is one of the major harmful components in groundwater. Dissolved SO4^2- concentrations, and δ^34S-SO4^2- and δ^18O-SO4^2- in groundwater from 14 boreholes and in gypsum from aquifer were analyzed. Results show that SO4^2- in shallow groundwaters originates from precipitation, sulfide oxidation, and dissolution of stratum sulphate, with a big range of δ^34S values, from -10.7‰ to 9.2‰, and addition of SO4^2- in deep groundwater results from dissolution of stratum sulphate, with bigger δ^34S values, from 7.8‰ to 18.5‰, compared with those in shallow groundwater. This research also indicates that three types of sulphate are present in the strata, and characterized by high δ^34S values and high δ^18O values-style, high δ^34S values and middle δ^18O valuesstyle, middle δ^34S values and low δ^18O values-style, respectively. The δ^34S-SO4^2- and δ^18O-SO4^2- in groundwater have a good perspective for application in distinguishing different groundwater systems and determining groundwater circulation and evolution in this area.

Coal resources are very abundant in Zibo, Shandong Province, China. A lot of mining sewages are discharged during the coal mining. The mining sewage is characterized by high ρ (SO 2- 4 ), hardness and totally dissolved solids (TDS). Mining sewage in the southern Zibo is acidic, where heavy metals and benzene are detected. The Xiaofu River is polluted when mining sewage flows into it, so that the Mengshan Reservoir is polluted by Xiaofu River. The groundwater is polluted in Zichuan by the leaking of the Xiaofu River. The polluted Xiaofu River is thus used to irrigate the farmland in Mashang Mengshui zone. The irrigation water affects the quality of shallow groundwater. The laboratory soil column test shows that SO 2- 4, Cl -, Ca 2+ and Mg 2+ can migrate through vadose soil, especially SO 2- 4 and Cl -.

Numerical simulation technology is nowadays an important means for groundwater issues because of its efficiency and economical advantages. But in case of natural hydrogeological boundaries are not within the interest area, it may be a big trouble to set boundary conditions of the model artificially without enough field investigation information. This paper introduced a method for solving such problem applying field pumping test and recovery test. The method was applied to build an in-situ leaching of uranium model. Results showed that the model boundary conditions can be set satisfactorily, and also the calculated heads matched the observed data well in both two models.

在咸水含水层中进行CO2地质封存是通过向含水层中注入CO2驱走咸水实现的。在大部分地下水被驱走之后,仍会有部分地下水残留在原来的岩石孔隙中形成残余水。残余水的形成过程及残余水饱和度的大小对CO2地质封存潜力及地质封存安全性等都具有重要影响。本研究通过超临界CO2排驱饱水岩心实验,研究了盐水种类对残余水的形成过程及残余水饱和度大小的控制作用。实验结果表明,在盐水浓度相同(35g/L)的情况下,超临界CO2排驱盐水的最终稳定不可再降的残余水饱和度是去离子水

Conditions of the water environment in the region of the Zhaling and Eling lakes, which are located in the frozen earth zone on the Qingzang plateau, are unique. The equilibrium of the water quantity of the two lakes is maladjustment under the condition of a dry and cold climate in which evaporation is greater than precipitation. The Zhaling and Eling lakes have been atrophying, leaving three lake terraces and star studded lagoons around the two lakes since Holocene. When these lagoons were separated from the original lakes, they became cut lake basins, and were transformed from fresh water lakes into salt water lakes, salt lakes or salt playas owing to strong evaporation. This kind of evolutionary process will continue in the future.
