Abstract – This Water Quality Index (WQI) for the ground water sampling locations were calculated , considering the observed and estimated ground water quality parameters values. Water quality assessment was carried out for the parameters like Electrical conductivity, pH, calcium, magnesium, sodium, total hardness, chlorides, sulphates, total dissolved solids, alkalinity and turbidity by the standard methods and procedures. Ground water samples were collected from 60 locations in Erode District during post-monsoon. WHO standards were estimated values based on water quality indices revealed that drinking water at almost all the locations were found to be highly contaminated, except at few locations, where it was found to be excessively contaminated for post monsoon. WQI provides an easy and rapid method of monitoring of water quality. It also becomes easier to compare the quality levels in different locations and to give priority for the required treatment to the location (which is severely affected) and also to select the type of treatment required.
