Abstract: (173 Views)
Introduction: Water is the most important life-sustaining substance for various living organisms, including humans. Among the most important physicochemical parameters in water include nitrite, nitrate, fluoride, dissolved oxygen, and turbidity. The presence of these parameters in drinking water at excessively high or low levels over the long term can pose health risks to the community. Therefore, this study aims to examine the concentrations of these physicochemical parameters in the drinking water sources of Ilam city from 2021 to 2023.
Materials and Methods: This study is descriptive-analytical. Considering the existence of 13 sources in Ilam city for supplying drinking water, data from all these sources were used. The study spanned three years from 2021 to 2023, with samples collected twice a year (every 6 months) for each parameter, resulting in a total of 78 samples (13×3×2) for each parameter. All samples were analyzed at the provincial health center laboratory after collection. Finally, the data was analyzed using Excel software and compared with WHO[1] guidelines.
Results and Discussion: The results showed that the highest average concentration of nitrate and nitrite in Ilam city's drinking water sources was found in Haft Cheshmeh well in the rural area, with levels of 54.17 mg/l and 2.22 mg/l, respectively, both exceeding national and international standards. Additionally, the highest average turbidity in Ilam city's drinking water sources was detected in Haft Cheshmeh well, at 5.92 NTU, surpassing both national and global maximum permissible levels. According to the table, the average fluoride concentration in Ilam city's drinking water sources was within the accepted range for all sources, adhering to national and international standards. The highest three-year average dissolved oxygen level was observed in Khorrmaroudi well, at 7.67 mg/l, which is within the permissible standards.
Conclusion: Since most physical and chemical parameter values in Ilam city are below national and international standards, the physicochemical quality of drinking water in Ilam city is not a health concern and is considered safe.
