Heavy Metal and Physicochemical Analysis of Well Water from Selected Areas in Wamakko Community, Sokoto State, Nigeria

Abstract

Aim: This research is aimed at investigating the heavy metals levels and physicochemical properties of well water from Wamakko community, Sokoto state, Nigeria. Study Design: Twelve (12) well water samples were collected from four different areas (A, B, C and D) in Wamakko community (n=3). Heavy metals concentrations (Cr, Cd, Fe and Pb) were determined using AAS and physicochemical analysis (pH, Temperature, Cl-, CO3, HCO3 and TDS) were carried out using standard analytic procedures. Place and Duration of Study: This study was carried out between November 2019 and January 2020 at Biochemistry and chemistry laboratory, Sokoto State University, Sokoto, Nigeria. Methodology: Heavy metals concentrations (Cr, Cd, Fe and Pb) were determined using AAS and physicochemical analysis (pH, Temperature, Cl-, CO3, HCO3 and TDS) were carried out using standard analytic procedures. Results: The levels of heavy metals investigated in all samples fell within the permissible limit approved by WHO and SON, with the exception of Fe and Pb. The physicochemical parameters investigated fell within the recommendable limit set by WHO and SON. Conclusion: The well water from the studied areas contain higher than normal levels of Pb & Fe, which can be toxic and may pose risk to human health. Therefore, awareness and periodic monitoring of well water from these areas are required since it’s the major source of drinking water for the people.
