Abstract
The paper deals with the spatial variation of various groundwater quality parameters and their interrelationship in lower Bhavani River basin, Tamil Nadu, India. Biotite hornblende gneiss and charnockite are the basement rocks in this region. Groundwater occurs under water table conditions in the weathered mantle of crystalline rocks. Interpretation of the analytical results of fifteen groundwater samples spread over the basin indicates that groundwater of the area is mainly alkaline and hard in nature. Magnesium is the second dominant cation next to sodium, which is highly responsible for the higher total hardness in groundwater. Higher concentrations of geochemical parameters are noticed in the eastern part of the basin. Concentrations of geochemical parameters exceed the maximum allowable limits for drinking at few locations. Thus, it is suggested that groundwater of these locations need to be treated before using for drinking purposes. Groundwater of the area is, however, suitable for irrigation.
