Effect of Eco- Geomorphological Factors on Physical and Chemical Quality of Groundwater Resources (Case Study: Bandargaz City)

Groundwater resources play a major role in providing drinking water. Geomorphological parameters are one of the factors that affect the quality of water resources. Physical and chemical quality of water can be affected by ecological factors such as geological formations and human activities, including agricultural, industrial and urban activities. The combination of these fields is studied under the term eco-geomorphology. This study consists of analyzing 48 samples in the year 1391. Physical and chemical parameters including EC, TDS, pH, color, turbidity, total hardness, amount of cations (sodium, calcium, iron, magnesium, potassium and magnesium) and anions (fluoride, chloride, nitrite, nitrate, sulfate and carbonate) were measured. The purpose was to assess the likely influences of the eco-geomorphological factors on physical and chemical properties of groundwater sources in Bandargaz city. The results show that according to the allowable water quality standards, the concentration of ions in the samples is desirable. In the well no. 2, the turbidity was 22 NTU and the fluoride concentration in the well no. 5 was 0.15 mg per liter which is the least amount. Considering the results of this study and the amount of rainfall in the area, planning for continuous monitoring of water resources, prevention of human activities and agricultural development around the wells, and sanitary disposal of the wastewaters, are the important factors in the quality management of the water sources.
