Evaluation of pollution susceptibility of Karst aquifers of Rewa Town (Madhya Pradesh) using "DRASTIC" approach.

Pollution susceptibility of groundwater of Rewa town situated on karstified Bhander limestones of the Bhander group is discussed in this paper. Pollution potential of selected localities in the town has been determined using the DRASTIC INDEX methodology. Pollution potential for these localities varied between 162 to 217. Shallow aquifers in karstified limestones having direct access to surface water were found more susceptible to pollution. Accordingly, remedial measures were suggested for minimising pollution.
