|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.|
