Water is a vital resource for the survival of mankind. The rapid urbanization, industrialization and uncontrolled use of chemicals in agriculture, deteriorate the quality of water and showed adverse effect on the aquatic environment. As a result, a huge population of human kind suffered with water borne diseases because of using the contaminated water. There are many parameters available, based on that the water suitability can be evaluated for potable use. Generally, the chemicals which present in water bodies such as Ca (Calcium), Mg (Magnesium), Chlorides (Cl- ), Sulphates (SO4 2- ), Total Hardness, Fluoride, Nitrate, Total Dissolved solids and the physical properties such as temperature, Electrical Conductivity etc are analyzed. On the basis of above mentioned physico-chemical parameters the goodness of water can be indexed by using the Tool Water Quality index (WQI) assessment which expressed quality of water in terms of some index number. Water quality index number stored all the information related to the water in single value. Various researchers have developed water Quality index region wise and proposed models for the anticipation of quality of water. This paper is focused upon the various ways for the detection of Water Quality index.

Keywords : Water Quality Standard, Water Quality Index, Physico- Chemical Analysis.
