Abstract

One of the most effective ways to communicate information on environmental status or trends to policy makers and the general public is with indices. Water Quality describes the information about chemical, physical and biological characteristics of water. Defining good or bad water quality is not as simple as it seems because it depends on the context in which it is used. For some quality parameters high value is better and for some low value is better according to various use of water. Generally, there are some standard techniques to measure water quality by Index number. To develop Water Quality Indices, before averaging one need to bring all the parameters to a common unit. This is the reason we have standardized gap between actual value and desirable dividing it by the range of that parameter, i.e difference between maximum and minimum value of that parameter.
