Study on Coastal Area Pollution by Anthropogenic Activities Along The Krishna – Eastern Delta

Abstract

Krishna Delta is located towards 90 km southeast of Vijayawada and 50 km to the south of Machilipatnam. Krishna Eastern delta area receives large quantities of pollution due to Seawater intrusion which directly affects coastal groundwater. Another main cause of pollution is due to excessive use of pesticides, discharging of chemicals and other anthropogenic pollutants from nearby households, aqua cultures .The quality of water is getting deteriorated due to unscientific waste disposal and unethical manmade activities. The waste disposal around the water bodies may damage the groundwater aquifers and physio-chemical properties of water. By testing the Surface waters, underground waters and comparing their properties with Drinking standards of water , we can know the extent of pollution caused in the coastal areas and suggest possible remedial measures.
