Abstract : Three water samples were collected around The Federal University of Technology, Akure (FUTA), Nigeria. The samples were analyzed for physicochemical properties such as temperature, acidity alkalinity, conductivity, chemical oxygen demand (COD), biochemical oxygen demand (BOD), nitrate, phosphate and sulphate, total hardness and suspended solids. The levels of heavy metals in the samples were also investigated. Microbial analysis was carried out on the samples to assess faecal contamination and type of bacteria present. For the physicochemical properties, chemical oxygen demand (COD) values for samples A and B deviated from 10 mg/L specified by WHO whereas the value for sample C was within the standard. Total alkalinity and phosphate values exceeded WHO standard limits. Also, the values of dissolved oxygen (DO) (8.28 - 10.97 mg/L) and pH (5.79 – 5.95) failed the standards set by WHO. Sample C was below WHO standard for total hardness having 93.60 mg/L as against 100 mg/L (minimum). However, calcium hardness, suspended solid, dissolved solids, BOD, and concentrations of heavy metals in the samples were within WHO permissible limits for drinking water. The microbial analysis showed that the samples contained some undesirable microorganisms such as E. coli (an indication of faecal contamination).
