This document outlines a proposed MSc research project that will evaluate the microbiological quality and potential health risks of tanker-supplied borehole water and roof-harvested rainwater in Nsukka, Nigeria. The study will involve collecting water samples from storage tanks, analyzing them for pH, temperature, and bacterial indicators. Isolates will be characterized, tested for antibiotic susceptibility, and pathogenic bacteria will be identified using PCR. Finally, a quantitative microbial risk assessment will estimate health risks associated with using the water sources. The expected outcomes are providing baseline water quality data, encouraging similar research, and publishing at least two journal articles.
