Water quality index (WQI) is valuable and unique rating to depict the overall water quality status in a single term that is helpful for the selection of appropriate Water Quality Index. 1.

In this context, a water-quality index is a grading system for com parison of various waters. A water-quality index is also the summation of the individual effects of the several properties Water Quality Water quality refers to the chemical, physical, biological, and radiological characteristics of water. It is a measure of the condition of water relative to the requirements of one or more biotic species and or to any human need or purpose.

Water quality indices are accredited to demonstrate annual cycles, spatial and temporal variations in water quality and trends in water quality even at low concentrations in an efficient and timely manner. Surface water quality is generally unsafe to drink without treatment. 3. Rainwater – Water that is collected and stored using a roof top, ground surface or rock catchment. The quality of rain water collected from a roof surface is usually better than a ground surface or rock catchment. water quality indices are such approaches which minimises the data volume to a great extent and. simplifies the expression of water quality status. Calculation of water quality index is based on. number of physico-chemical and bacteriological parameters. chemical and biological processes, which can occur in water are temperature –dependent.

Water temperature needs to remain fairly constant so aquatic fauna can survive. Though high turbidity is often a sign of poor water quality and land management, crystal clear water does not always guarantee healthy water. Extremely clear water can signify very acidic conditions or high levels of salinity. chemical and biological processes, which can occur in water are temperature –dependent. Temperature affects a number of water quality parameters Such as dissolved oxygen which is a chemical characteristic Conductivity: is a measure of water capacity to convey an electric current. Most inorganic acids, bases and salts are good conductors Water Quality Surveys on the understanding that the new book would describe, in a much broader way, the application and interpretation of water quality information in water resource management. The methodological and technical aspects could be largely omitted since the reader could be referred to the above-mentioned GEMS/WATER literature. 7.
