The Groundwater Quality Evaluation and Analysis of its Changing Trend in Major Cities of Xinjiang
Abstract:
In order to identify the main factors causing the changes of groundwater quality in major cities of Xinjiang and provide the basis for the prevention and control of groundwater pollution, the monitoring statistics of 17 groundwater samples from the same positions or similar positions in nine major cities of Xinjiang in April-June 2003 and in October-November 2011 are used to classify the groundwater quality of the nine cities in 2003 and 2011 by the “one vote veto” system. The groundwater quality is evaluated with city as the basic unit and according to Quality Standard for Groundwater (GB/T 14848-93). Meanwhile, the changing trend of the major ions in the groundwater is analyzed. The results show: the overall quality of the groundwater of each city was good in 2003 but deteriorated seriously in 2011; Urumqi and Shihezi were the cities where the groundwater quality was seriously deteriorated; the concentrations of most ions and other quality indices in the groundwater all presented a rising trend
