Abstract
The present study intended to calculate water quality indices (WQIs) for six different areas of Batlagundu, Dindigul District in order to ascertain the quality of water for public consumption and other domestic purposes. This paper deals with the study on the influence of environmental parameters on the water quality. In this study, five WQIs have been determined on the basis of 24 physico-chemical parameters. The parameters, namely, temperature, pH, sulphate, potassium, nitrate, phosphate, DO, BOD and COD were within the permissible limits of BIS and WHO while other parameters such as turbidity, total dissolved solids, electrical conductivity, total hardness, total alkalinity, calcium, magnesium, chloride, nitrite, fluoride, sodium and iron were found to exceed the limit. Results of WQIs indicated that the quality of water was deteriorated by natural and anthropogenic sources. The aforesaid study showed that the groundwater of the above-selected sampling sites was not safe for human consumption but could be used for domestic purpose after purification.
