The study determined the physicochemical and microbiological properties of the water supply sources at the University of Port Harcourt; as well as employed a triangulated descriptive cross-sectional retrospective survey, to identify the factors that guide consumers’ selection and consumption of drinking-water, and equally assessed their perception of drinking-water quality and its impact on public health. The pH of all the samples was found to be acidic, and the total hardness was very low. Moderate sodium and slight calcium levels were observed in the samples. Seventy percent (70%) of the samples indicated the presence of pathogenic coli form organisms: Klebsiella spp., Escherichia coli and Salmonella spp. The most probable number (MPN) of the pathogens ranged between 3 – 93 per 100 ml. Three sources flouted the USA Environmental Protection Agency (EPA) criteria of a minimum horizontal distance of 50 ft clearance from underground septic sewage tanks and water wells. A total of 500 questionnaires were administered, and most respondents relied solely on physical assessment of their drinking-water. A rigorous sensitization and education is advocated to improve students’ perception of drinking-water quality; and simple methods should be adopted to eliminate bacteriological contamination and assure the total quality of the water supply framework
