Effect of change in ecosystem on ground water quality

Abstract

The variation in cholride and magnesium in the ground waters of Andhra Pradesh for the last half a decade was mapped and compared with the population patterns align obtained from recent census operations. It is observed that both the ions give rise to similar patterns apparently controlled by the hydrogeological settmg, physiography. etc Significant differences were, however. noted in certain areas. The influence of  977 cyclone was clearly decipherable in coastal areas Saline matter carried by the cyclone winds was confined to the region between Vinukonda in Guntur district and Eluru in West Godavari district.

The Coastal parts and Rayalaseema show increasing salinity in ground waters with rising population. Similar effect is not felt in Telengana area presumably because of Jag in transport of salt waste into ground water.
