A total of 10 samples including 5 from surface water (surrounding industries leather ,power, steel, electronics, chemical, matrices, etc.), and 5 from open well water of all bore wells in the vicinity of the SEZ were collected in November 2011, the samples in the SEZ of mambattu, the industry like leather, Power, Steel, Electronics, Chemicals, Matrices are located were analyzed for various physico chemical parameters like temperature, pH, EC,DO, Total Hardness, BOD,COD,TDS, Sulphates, Nitrates, Chloridres and heavy metals like Fe, Pb, Zn, Mn, Cd .The results were compared with US EPA and WHO standards for both surface and open well water collected from above said area. All physicochemical parameters are within the permissible limit except Fe concentrations which were found above the permissible limit. Key words: Surface water, Open well water, Physico - chemical Parameters, Water Quality Index, WHO. ______________________________________________________________________________ INTRODUCTION Open well water and surface water has been using for domestic and industrial water supply and irrigation purposes all over the world. There has been a tremendous increase in the demand for fresh water due to rapid growth of population and the accelerated pace of industrialization. Industrial estates are established to fulfill the demand of the growing population in the country 1-2 . The introduction of industries on one hand manufactures useful products but at the same time generates waste products in the form of solid, liquid or gas that leads to the creation of hazards, pollution and losses of energy. Most of the solid wastes and waste waters are discharged into the soil and water bodies and thus ultimately pose a serious threat to human and routine functioning of ecosystem. In India groundwater is used for domestic and agricultural purposes. Similarly most of the industries are using ground as well as surface water for their manufacturing and cleaning purposes, this used water come out as a waste water. Heavy metals are basically present in groundwater but these play an important role in determining the quality of water for drinking purposes. Metals are considered toxics and when they enter the body more than the prescribed limit they start causing harm. In the same way many physicochemical parameters play an important role in determining the quality of water. According to WHO organization, about 80% of all the diseases in human beings
