Investigating the Physicochemical Status of the Sources of Drinking Water Supply in Asadabad City During 2011-2018

Background and Objectives: Sufficient sources of water with acceptable qualities are vital for human survival. Health development and environmental protection have been always depended on providing healthy water supplies. The purpose of this study was to determine the physiochemical status of drinking water sources in Asadabad city during 2011-2018. Materials and Methods: This descriptive study investigated 19 parameters of  physicochemical quality of water taken from General Office of Water and Wastewater of Hamedan Province in 2011- 2018 and 32 samples taken in 2018 from 8 underground water sources. Finally, the data were analyzed by descriptive statistical tests (compared with the national standards of Iran). Results: The results showed that the average  pH was 8.30±0.37, turbidity 0.77±0.5 NTU, temperature 9.12±2.20 C, electrical conductivity 418.5±307.22 microseisms per cm, total soluble solids 236.25±174.5 mg/l, total hardness 214.12±162.13 mg/l calcium carbonate, total alkalinity 186.63±21.77 mg/l calcium carbonate, nitrate 15.66±25.85 mg/l, nitrite 0.280±0.110 mg/l, fluorine 0.53±0.22 mg/l, chlorine 36.37±85.63 mg/l, sulfate 14.5±13.49 mg/l, carbonate 2.75±18.64 mg/L, bicarbonate 133.25±56.58 mg/L, phosphate 0.20±0.39 mg/L, sodium 0.02±0.028 mg/l, manure 5.5±3.74 mg/l, potassium 0.0 mg/l, and iron 0.072±0.14 mg/ml, which were consistent with the similar results of the past five years. Conclusion: According to the results, the water samples tested for physicochemical parameters were within the range of Iranian National Standard. However, some chemical parameters have increased in 2018 compared with the past years.
