Physicochemical Analysis of Well-Water Samples from Villages in Bwari Area Council-Abuja, Nigeria

Abstract

This study involved the determination of the trace metals and some physiochemical properties in well-water samples taken within selected villages in Bwari Area Council, Abuja, where well water samples are not treated before consumed. The purpose was to ascertain the quality of water from these sources. The collected water samples were subsequently analyzed for the following parameters: Na, K, Ca, Zn, Cl, Mg, and SO4 2-, using APHA standard methods of analysis. The data showed the range in variation of the investigated parameters in samples as follows: pH 6.2-6.7, electrical conductivity, 90-570µs/cm, total alkalinity 48-66 mg/L, total hardness 40-60 mg/L , Na 26-542 mg/L,K 56-218 mg/L, Ca 0.44-2 mg/L, Cl- 29.82-45.44mg/L, SO4 2- 7.7-14.7 mg/L, and Mg 1.01-3.64 mg/L. The concentrations of most of the investigated parameters in the well water samples from these villages were within the permissible limits of the World Health Organization drinking water quality guidelines except sodium and potassium. The linear correlation test conducted indicated that Electrical conductivity, chloride, pH and total alkalinity were slightly correlated
