Growndwater Quality at Down Stream Area of River Basin by using Geospatial Engineering

Abstract

Water is the most precious natural resource for the survival of any living organism gifted by GOD which is available as surface water and Groundwater. Rivers are the most important surface water sources to meet the daily requirement of water demand for various activities of the people at any area around the whole world, but in the current scenario rivers are getting pollute due to various natural and manmade activities especially at the down steam areas of rivers. The major source for downstream pollution are due to the runoff of the nearby areas and also some times through the upstream polluted water flow of the rivers which is quite common in the developing cities of our country either by the negligence of the people and or due to the unaware of un desirable consequences of coastal pollution on the environment as well as on the living standards of the people living near to the coastal belts. Geo spatial technology is the advanced tool in water resource engineering to understand the exact existed scenario of groundwater prospects with high accuracy and reliability. The present study is carried out at downstream area of Krishna River in Guntur district of Andhra Pradesh, all the groundwater samples were collected from hand pumps and the bore wells at study area for three times and the average values are considered as final values, Analysis was carried out by using standard analytical procedure and the final average results were projected in GIS maps and then correlated with IS–10500-2012 drinking water quality standards to assess the present condition of groundwater at study area.
