Assessment of pollution in ground water in Krishna Delta

Abstract

The maintenance of groundwater quality is more necessary due to increasing demand and need for various purposes such as drinking and cultivation of crops etc. Over-exploitation without proper planning decreases groundwater quality which affects adversely the health aspects of living beings and decrease in agricultural output.. Hence a detailed survey conducted for examine groundwater pollution in Doppalapudi (Latitude: 15.97410 N; Longitude: 80.50700 E) and Mannava (Latitude: 16.48100 N; Longitude: 80.57870 E) regions. The formations in the study area belong to sand and clay of Recent Era. Groundwater is analyzed for various physico-chemical parameters. Most of these parameters values are excess over prescribed values for drinking water. Values of quality methods such as Percent Sodium etc., suggest groundwater not suited to cultivation. Present attempt is made to examine the various controlling factors. This study is useful for similar studies throughout the world. Appropriate remedial measures are suggested for development of ground water quality to maintain environmental balance in study area.
