In assessing the quality of water within the Adekunle Ajasin University, Akungba Akoko, Ondo state Southwestern Nigeria, 12 representative samples were analysed from 3 hand dug wells. 3 streams and 6 boreholes for their physical and chemical parameters. The result show that the appearance of water samples varied and they were all clear. Turbidity ranges from 0.050-0.195NTU which indicate that the samples turbidity are below the W. H.O guideline of 5.0NTU. Conductivity ranges from 0.04 (mho/cm) to 0.11 (mho/cm), for hand-dug wells the 0.02 (mho/cm) to 0.05 (mho/cm) and for stream’s the conductivity ranges from 0.02 (mho/cm) to 0. 08 (mho/cm).The chemical parameters analyzed for the samples include pH, total dissolved solids, total Hardness, and concentration of ions. The total dissolved solid is highest in borehole 1 with a value of 700ppm while stream 2 and hand dug well 3 has the lowest value of 100ppm respectively. The Total Hardness is highest in borehole 4 with value of 77.78 and lowest in borehole 3 with value of 16.70. The value of the calcium concentration in the water samples range from 7.21mg/1 to 40.08mg/1. The W.H.O recommended minimum and highest desirable levels are 75m/1 and 200mg/I respectively The magnesium concentration of the samples ranges from 2.43mg/1-41.31mg/l. According to the World Health Organization permissible limits for minimum and maximum values are given as (50mg/1 and 150 mg/l),The results of the analysis compare favourably with the standard practice, the pH value also suggests that most of the water samples are slightly acidic but only a sample falls within the alkalinity range, the geology of an area influences groundwater chemistry while the activity of human influences the quality of groundwater.
