Background: Consequent on the importance placed on potable water across the globe and the recurrent water borne diseases inherent from the consumption of polluted water, there is the need to periodically monitor the quality of water utilized domestically and industrially. Objective: The study is aimed at evaluating the physicochemical and microbial analyses of water samples from hand-dug wells around The Federal University of Technology, Akure, Nigeria. Materials and Methods: Water samples were collected from cased wells at selected locations around the North and South Gates of the Federal University of Technology, Akure(FUTA), Nigeria. The samples were subjected to physicochemical and microbiological analyses using standard analytical procedures. Results: The following results were obtained: pH (5.61 - 6.77); chloride (45.05 - 155.70 mg/L); nitrate (0.027 - 2.800 mg/L); sulphate (23.20 - 244.00 mg/L); phosphate (BDL - 20.52); total hardness (36.20 - 208.74 mg/L); sodium (9.51 - 58.64 mg/L); potassium (1.62 - 10.00 mg/L); temperature (26.00 - 28.1oC); turbidity (0.1 - 0.6 NTU); conductivity (129.00 - 586.00 µS/cm); acidity (63.00 - 108.00 mg/L); dissolved oxygen (DO) (29.17 - 50.00 mg/L); biochemical oxygen demand (BOD) (1.00 - 400.00 mg/L); and alkalinity (43.26 - 382.20 mg/L). The levels of total solids, total suspended solids and total dissolved solids were 0.19 - 1.15, 0.02 - 0.07, and 0.16 - 1.08 mg/L, respectively. Metal analysis showed the presence of K, Na, Mn, Fe, Cu, Zn, and Cr in varied amounts. However, Pb was below detection limit (BDL) in all the water samples. Microbial analysis revealed the presence of Staphylococcus aureus, Salmonella sp, Klebsiella sp, Shigella sp, Enterobacter sp, E. coli, and Bacillus sp. Conclusion: All the results obtained were compared with the permissible limits of the World Health Organisation (WHO), and it was observed that all the water samples studied did not conform in totality with the standards stipulated by WHO.
