Heavy metals are relatively dense metals noted for their potential toxicity. This work was designed to determine the physiochemical properties and heavy metals levels in domestic water sources in “Esan” commonly referred to as Esanland in Edo State, Nigeria. These water sources serve as the sources of drinking and general domestic water sources for the people. Concentration of Cadmium (Cd), Lead (Pb), Mercury (Hg), Nickel (Ni) and Arsenic (As) as well as pH, Sulphate and Nitrate were determined in the Borehole water, River water and water from Rain fall on metal roofing sheets collected into ground water-storage tanks in the upper and lower plateau, in Esan Edo State, Nigeria. Water from the Ikogosi Warm spring (IKWS) Ekiti State served as control. Results of the analysis showed that Arsenic and Mercury levels were below the detectable limit. Pb concentration in the upper plateau river was significantly higher (0.02 ± 0.00; P=0.02) in comparison with the controls, nitrate was significantly higher for River in the lower plateau and upper plateau. And Sulphate also was significantly higher for Borehole samples from Irrua (4.19 ± 0.35; p = 0.04) and Uromi (5.12 ± 2.93; p=0.01). Cd and Ni levels were not significant.
