description | Springs as one of the groundwater sources and suppliers of high volume of river basin discharge have been less analyzed and studied. The origin of these resources, due to the passage of natural heights and filtration, has a good quality and only some formations or human activities cause a change in the quality of these resources. This study evaluated the quality of springs in Ajabshir study area in the east of Urmia Lake in 2018. According to the type of geological formations, discharge and location of springs in the region, 13 springs were analyzed for qualitative analysis and evaluation of qualitative changes. Studies have shown that 100% these springs are very good quality in terms of drinking, and the GQI quality index is 33.23-95.32, indicating good to excellent condition for these resources. In terms of exploitation in the agricultural sector, the only issue was the high level of electrical conductivity (157-6490 µs/Cm) in some springs, and the alkalinity of all springs was in class S1 in Wilcox diagram. The quality situation from the industry point of view also indicated a low range of changes, and 77% of the springs in the region were corrosive. Evaluation of water source in this area showed a high ratio of sodium to chlorine and differences in calcium and sodium origin, so that the initial sections of the study area and the east of the area had magnesium source and the rest had calcium source. Finally, the study of geological formations showed their low impact on quality and the high concentration of nitrate in the part leading to the plain and aquifer due to human activities and sewage leakage was evident and reached 27 mg/l. |
