Abstract: Physico-chemical quality of borehole water and pipe-borne water from selected second cycle institutions in the Accra metropolitan area in the Greater Accra region of Ghana was evaluated. A total of Seventeen (17) samples were collected from eight (8) boreholes and nine (9) pipe-borne water sources respectively. The parameters determined were; physico-chemical (pH, Temperature, Conductivity, Total Dissolved Solids, Total Suspended Solids, Salinity, Turbidity, Colour, Alkalinity and Total Hardness), anions (Chloride, Fluoride, Sulphate, Phosphate and Nitrate), some trace metals and essential metals (Iron (Fe), Zinc (Zn), Lead (Pb), Sodium (Na), Potassium (K), Magnesium (Mg) and Calcium (Ca)). Standard methods were employed for the determination of all the parameters. From the results, pH of both the borehole and pipe-borne water samples were acidic to neutral (range: 4.78-7.38). Both water sources were moderately soft to slightly hard (range: 14.67-444.33 mg/l). The anions observed in the water sources were within the WHO guidelines except chloride concentrations in the borehole water which were above 250 mg/l. Magnesium, Zinc and Iron concentrations were below the WHO limits of 330 mg/l, 3.0 mg/l and 1.0 mg/l respectively. While Cadmium concentrations in both water sources were below detection, lead concentrations exceeded the WHO limit of 0.01mg/l. The results suggest that most of the borehole and pipe-borne water sources in the second cycle institutions are acceptable for household utilization except for the isolated cases of lead contamination.
