Evaluating the spatial segregations of underground water resources quality (case study: Dolat Abad, Dashtab, Soltani and Soghan stricts in Kerman)

Abstract:
The specific climatic and geomorphological conditions of arid and semi-arid regions, has made the underground water resources as the main resource of water supply in these regions. Accordingly, managing these water resources requires accurate evaluation of quality and quantity of water reservoirs, its access range (availability) in each region, and recognizing the environmental processes that govern these resources. In this research the quality of underground water resources in DolatAbad, Dashtab, Soghan and Soltani have been studied. Meanwhile, the difference between various quality indices have been measured and compared quantitatively. The results of variance analyze, prove significant difference between various indices. The results of mean comparing test for error likelihood less than (a˂0.01) for each above indices, separate the underground resources of various regions in diverse groups. According to EC, TDS, CL, SO4, Mg, Na, SAR and TH indices, the underground water resources of Dolat Abad and Dashtab, place in group one, and Soghan and Soltani regions take place in group two. Also, according to Ca index, the underground water resources of studied regions, were categorized in 3 various groups. Group one, including Soltani and Soghan regions, group two including DolatAbad region, and group three including Dashtab district. Also, placing the underground water resources of all districts in one group according to Hco3 index, indicates that there isn’t significant difference for quality of underground water resources in studied regions, according to Hco3 index. the analysis test of correlation between various indices for measuring the quality of underground water resources in the studied regions, indicates the maximum correlation existed in likelihood level of %1 between underground water level and PH indices.
