ABSTRACT: The name of water is called life. Providing safe drinking water is one of the momentous public health precedencies and the drinking water quality is closely associated with human health. The most important human well-being is affordable, abundant, and clean drinking water. This study has been conducted for assessing the drinking water quality of various locations in Noakhali. Total of nine water samples have been collected from three different locations (Sadar, Begumgonj, and Hatiya). Each sampling location consists of three separate sampling points. The samples have been analysed for their physical-chemical and microbiological quality in order to observe health impact. Physicochemical parameters of the collected samples like Temperature, pH, Electric Conductivity (EC), Total dissolved solid (TDS), and Salinity have measured by Multiparameter meter and Microbial parameters like Total Viable Bacterial Count (TVBC), Total Coliform (TC) and the presence of E. coli have also examined. All the parameters have analysed and compared with WHO drinking water quality standards to understand the overall water quality status of the study area. The study has shown that the water samples in almost all the locations have been contaminated by microbial contamination and the range of the physicochemical parameters was not suitable for consumption. Preliminary treatment is needed prior to using the water for drinking purposes and necessary steps should be taken for alternative safe sources of drinking water.
