Bacteriological and physicochemical quality of drinking water and associated risk factors in Ethiopia

Abstract

AbstractThe problem of drinking water quality is critical public health concern in Ethiopia in which poor sanitation and the use of contaminated water are blamed for 80% of disease cases. This is very important for monitoring water supply to identify and address any potential contaminants as well as investment in infrastructures and treatment technology that can improve water quality. This review aimed to evaluate the quality of drinking water in Ethiopia based on the concentration status of physicochemical and bacteriological parameters and its risk factors. Different studies in most parts of Ethiopia indicated that physicochemical quality of drinking water meet the prescribed standard limit, but in some parts of Ethiopia, water did not meet quality standard. Accordingly, an overall coliform count of drinking water in different areas of Ethiopia indicated that drinking water was at risk. Microbiological implications in the country showed that considerable amounts of drinking water were tainted with E. coli and fecal coliforms, which indicated the existence of dangerous pathogens. The quality issues several parts of Ethiopia were significantly influenced by poor handling practices. Consequently, proper handling practices of drinking water both at the source and point of use is essential to have a safe water supply and thereby protect public health. In order to guarantee that people have access to safe and clean water. The review’s findings underscore the urgent need for enhanced water quality monitoring and treatment in Ethiopia.
