ارزیابی کیفیت هیدروژئوشیمیایی آب زیرزمینی حوزه سیاهو، شمال شرق شهر بندرعباس

Background and Objective: Water quality assessment is an important step for optimal and proper use of water resources for drinking and selection of suitable and consistent water quality patterns. Therefore, the necessity of studying water quality characteristics in water resource management programs has been highly considered. Materials and Methods: In this study, the hydrogeochemical quality of groundwater resources in the Siahoo region of Bandar Abbas was studied for drinking, agricultural and industrial purposes. Qualitative parameters of three wells, three springs, one juicy aqueduct and one surface water sample were used as input data. Water quality characteristics and charts were evaluated using Aq.qa and AquaChem software. Results: Groundwater of the studied area was in the category of very hard water. According to the PIPER chart, the dominant hydrochemical facies were sulfatecolic and chloroformate species. According to the Willcox and Schuller qualitative index, groundwater for agricultural use was moderate and was acceptable for drinking water. In terms of the saturation index of islands, the existing water resources are corrosive to the sediment. Conclusion: The data of this study indicate that one of the problems of the available water resources in Siahoo region is the high amount of salt and soluble materials, which show the effect of geological formations (evaporation, Chile, carbonates) and salt domes on the groundwater resources and reduction of the quality of water resources.
