    A concentration of heavy metals (Pb, Cd, Zn), an electrical conductivity and water density at Sungai Singingi by using an experimental method have been carried out. Water sampling at Sungai Singingi that crosses the village of Koto Baru is conducted three times at five points where the distance between the point is 10 m as long as 40 m. The equipment used are the concentration of heavy metals by using Atomic Absorption Spectrophotometer (AAS), the electrical conductivity by using a Total Dissolved Solid Meter (TDS meter), and the density of the water by using a Hydrometer. The results shows that the concentrations of heavy metals lead (Pb) are highest in five points, namely 0.0889 mg/l and the lowest one is of -0.0296 mg/l. The highest the concentration of heavy metal cadmium (Cd) in the five points is 0.0028 mg/l and the lowest one of -0.0004 mg/l. The highest concentration of zinc (Zn) is 0.0228 mg/l and the lowest one is 0.0020 mg/l. The highest electrical conductivity of water in the five point is 31.8 μmho/cm and the lowest one is 28.3 μmho/cm. The highest water density in five point is 1095.9 kg/m3 and the lowest one is 1031 kg/m3.
