The quality and suitability of boreholes water quality in the Rivers State University of Science and Technology were assessed for potability and irrigation purposes by analyzing the water for physico-chemical parameters, microbial contents and irrigation indices using standard methods. The results obtained were compared with permissible limits for drinking water provided by World Health Organization and Standard Organization of Nigeria The results showed pH ranged from 4.09 - 6.77 at 26.4 - 30.3°C, Turbidity <0.01 NTU in all the samples, Electrical Conductivity 20 - 407 mS/cm, Salinity <0.01 - 0.20‰,TDS 12 - 274 mg/l, Chloride <1.0 - 12.3 mg/l, Sulphate <1.0 - 15.5 mg/l, Phosphate <0.05 - 1.9 mg/l, Nitrate 0.30 - 6.20 mg/l, Total Alkalinity (as CaCO3) 2 - 8 mg/l, Total Hardness <0.1-34.6 mg/l, Calcium <0.08 - 9.2 mg/l, Magnesium <0.05 - 2.8 mg/l, Sodium <0.01 - 44.62 mg/l and Potassium <0.01 - 11.88 mg/l. The results of microbial analyses showed Total Heterotrophic Bacteria population ranged from Nil - 3000 cfu/ml, Total Coliform Bacteria 0 - 210 MPN/100ml while Faecal Coliform Bacteria were not present in all the samples. The Groundwater within the University is fresh, soft and has low pH. The water in some parts had high microbial count and therefore not suitable for drinking. The ground water in the area should be regularly monitored and treated to avoid serious pollution problems. The irrigation indices showed the water is suitable for irrigation and other purposes.
