This study was designed to detect heavy metals level in water collected from Daura gypsum mining site, Yobe State, Nigeria. Samples were collected and analyzed using Atomic Absorption Spectroscopy. The level of Pb, Ni, Cd, As, Cu and Zn, were assessed. Also the conductivity of the water samples detected using Conductivity meter. The result shows significant level of As at 0.0382 mg/l, Cd at 0.06-0.18 mg/l and 0.9852 mg/l for Ni which exceeded the WHO limit (0.01 mg/l). Cu, Zn, and Pb were detected at 0.95mg/l, 1.77 mg/l and 0.244 mg/l respectively. Cu, Pb, and Zn were found below the WHO, USEPA limits. This may bring kidney related risk to the people over a long period of time, Therefore , incorporation of ion exchange, reverse osmosis or adsorption in water sources will help reduce the heavy metals burden of the public in the area.
