Abstract :
Background and Objective: In many villages of Robat Karim city, such as Hossein Abad, Shahr Abad, Elard and Jum Abad, they have faced a severe problem of water shortage during the past years. Sazi will have the possibility of providing a suitable solution to reduce the expenses incurred which is a waste of capital and has quantitative and qualitative destructive effects on wells and drinking water sources. At the same time, it should be mentioned the important role of quantitative and qualitative parameters of drinking water resources and its impact, because the lack of monitoring and comparison with drinking water standards can be the source of creating or intensifying other pollutions, hence the purpose of this research is to identify the situation The quality of drinking water is extracted from the wells of Robat Karim city.
Material and Methodology: In this stage, sampling was done from the water wells of the villages of Robat Karim city. The statistical population of this study included at least 6 wells in the villages of Robat Karim, including: 3 wells over 10 years old, 2 wells under 5 years old, and at least one new well in Hafar. The sampling method was also used in the form of sampling raw water from these wells to measure the quantitative and qualitative parameters of drinking water. The issue was resolved.
Findings: In 2016, the concentration of turbidity in the well of Shahrabad due to the location of the well next to the black water drainage system and the presence of clay layers on the wall of the well caused the potential of increasing the concentration of turbidity in this well to be expected. The trend of hardness concentration (TH) in the northwest (Shahrabad-Eilat region) and southeast (Shahristank-Vohnabad and Aliabad region) due to the presence of calcium (Ca) and magnesium (Mg) layers and the dominance of chalk-marl layers (calcium sulfate) has caused the dissolution concentration of these layers in aquifers and the increase in the concentration of calcium, magnesium, hardness in these areas shows an increasing trend. Accordingly, according to the increase in the concentration of total dissolved solids in these ranges, the concentration of TDS and following these conditions, the concentration of EC is also increasing.
Discussion and Conclusion: In the area of Shahrabad, due to the location of the well approximately the village, the possibility of entering domestic sewage and increasing the concentration of nitrates in this area can be justified. In addition, in the years 2016 and 2017, physical parameters such as EC, TDS and TH are somewhat higher in the villages of the northwestern areas of Shahrabad and Anjamabad and the southeastern areas of Shahristanak, Vahanabad and Hakimabad due to geological evaporation conditions. Considering the prevailing conditions in the northwest villages of Rabat Karim villages in Anjam Abad to Shahr Abad, it is better to avoid drilling wells for the future of drinking water supply in this area.
