This study characterizes groundwater's physicochemical parameters and bacteriological analysis in Bwari, FCT, Nigeria. Nine boreholes were randomly selected for sampling. Sample locations include Dutse Sokali, Dutse Baupma, Dutse Jabu, Kogo, Bwari, Sabon Gari Bwari, Dimas Isuwa Street, Bwari, Dutse Alhaji, Tasha Bwari and F01 Kubwa Bwari. The parameters studied were pH, Electrical Conductivity, Fluorine, Nitrate, Total Dissolved Solids, Chloride, Sulphate, Biocarbonate and bacteriological assessment. In addition, a comparative analysis was done using the World Health Organization water quality standard (WHO). The comparative analysis shines a light on the groundwater contamination in the area.
