Determination of lead concentration in well and borehole water in Zaria, Nigeria

Abstract

In this study, lead concentration of sixty well and five borehole water samples collected from Zaria and environs was determined. Lead concentrations ranged from 0.000786 to 0.0595mg/L, with 91% of samples above the 0.01mg/L WHO drinking water guideline. Borehole water samples were found to contain less lead compared with the shallow well water samples studied. In this study Atomic Absorption Spectrophotometric (AAS) method was used because of its simplicity and accuracy.
