The aim of this study was to evaluate and compare the drinking water quality for four residential locations at the University of Benin, Benin City, Ugbowo Campus by carrying out physical and chemical analysis on water samples and access their safety by calculating their water quality index values and comparing with those of the Nigerian Standard of Drinking Water Quality (NSDWQ), and World Health Organization (WHO). Acomprehensive physical and chemical assessment was conducted on water samples collected from four residential areas within the University of Benin: Senior Staff Quarters (SSQ), NDDC Quarters, Junior Staff Quarters (JSQ), and Hall 4 Hostel. Key water quality parameters analyzed included pH, turbidity, electrical conductivity, Total Dissolved Solids (TDS), biochemical oxygen demand (BOD), mineral content, and the presence of heavy metals. Heavy metal analysis was performed using an air-acetylene flame atomic absorption spectrophotometer. Water samples from the Junior Staff Quarters had better physical parameters while water samples at the hall 4 residence had the least quality in comparison to SON and WHO standard. However, all water samples were found to be acidic according to their pH values of 5.1 5.2, 5.4 and 5.3 for SSQ, NDDC, JSQ, Hall 4 Hostel respectively. The result gotten from water quality index calculation was 68.076, 97.10, 97.59, 94.60 for SSQ, NDDC, JSQ, Hall 4 hostel respectively.The water sample for SSQ is poor, for NDDC is bad, for JSQ is bad and that for Hall 4 Hostel is very bad
