Physio chemical Water Quality Assessment from Source to Point of Use: The Case of Woldia Town, Ethiopia

Abstract Sanitation and access to clean drinking water are major global issues. A major problem in many nations' water supply systems is the deterioration of water quality, which can be caused by a variety of interrelated physical, chemical, and biological factors. The issue is more serious in developing nations such as Ethiopia. Thus, the aim of this study is to evaluate the variation in drinking water quality, both seasonal and spatial, in Woldia town, Amhara Regional State, Ethiopia. The research was carried out between July 2023 and December 2022. A total of 200 water samples were collected from each sample site during two rounds of sampling during the dry and wet seasons. Water sources (n = 4), reservoirs (n = 2), and distribution are the 12 sampling points that are chosen in accordance with the WHO sampling points selection principle. The analysis of the data was done with SPSS 26. Descriptive statistics like mean and standard deviation were employed in the study, along with inferential statistics like Pearson correlation and analysis of variance (ANOVA). To observe the significant difference between sampling points at p<0.05 and the significant correlation between the parameters. The outcome demonstrated that, in both seasons, all chosen physicochemical parameters were found to be within the acceptable limit of WHO and Ethiopian standards, with the exception of total hardness, free residual chlorine, and water temperature.
