ABSTRACT

Water quality index (WQI) is a dimensionless number that combines multiple water quality factors into a single number by normalizing values to subjective rating curves. The present work is aimed at assessing the Water Quality Index (W.Q.I) of ground water of some towns of villupuram district. Physicochemical parameters were monitored for the calculation of W.Q.I for the sep 2016. The physicochemical parameters namely pH, Total hardness, TDS, Alkalinity, Chloride, Sulphate, Fluoride, Nitrate,, EC and Ammonia was determined and it is found that their values were exceeding the permissible limits as prescribed by WHO. The analysis reveals that the ground water of the area needs some treatment before consumption, and it also needs to be protected from the perils of contamination.
