The levels of trace metals and major chemical constituents in 28 ground water samples of Korangi Industrial Area (KIA) and its adjoining areas were determined to assess the impact of uncontrolled disposal of industrial waste water on the quality of water. The concentration of metals viz. Zn, Mn, Fe, Cu, Pb, Cd, Ct, Co and Ni, were found to be excessive higher than the WHO recommended limits. The significantly higher concentration of major chemical constituents and trace metals in KIA water samples than the corresponding concentrations in the adjoining areas samples clearly indicated that the contamination in ground water of KIA was primarily due to percolation of industrial waste water into the acquifer of the area. The positive and high correlation co-efficient values (r) showed strong correlation among the metals and also suggested high and consistent trace metals concentration in the ground water under investigation.
