Physico-chemical analysis of ground water samples from Nasarawa LGA, Kano State-Nigeria

Abstract

This study was carried out to access some physico-chemical quality of borehole water used for drinking and domestic purposes in Nasarawa Local Government Area of Kano Metropolis. Twenty water samples were randomly collected from different sampling sites and were analyzed for their levels in pH, Alkalinity, Conductivity, Total dissolved solids (TDS), Total hardness, Permanent hardness, temporary hardness, Calcium hardness and Magnesium hardness, using standard methods of analysis. The results obtained indicated that the mean pH level was 7.76+0.277, mean alkalinity level was 714.70+336.701mg/L, the mean conductivity level was found to be 1057.40+669.092μScm-1: Total dissolved solid (TDS) had mean value of 708.46+448.286mg/L Total Hardness had mean level of 652.35+311.241 mg/L: Permanent hardness had mean level of 400.20+253.767mg/L. The mean value of Temporary hardness was found to be 252.15 + 181.915mg/L while mean calcium level was 237.80+139.259mg/L; and finally the mean magnesium level was found to be 414.10+254.057mg/L. The results of this analysis indicated that pH, conductivity and total dissolved solids were within the acceptable range recommended by World Health Organization. (W.H.O), while Alkalinity, Total hardness, Permanent hardness, Temporary hardness, Calcium hardness and Magnesium hardness were all above the safe limit recommended by World Health Organization.
