Assessment of Groundwater Quality for Irrigation Use Chemical Analysis of Konaseema in the Godavari River Basin, East Godavari District, Andhra Pradesh, India

The present paper deals on ground water quality and Hydrochemical anamoly, The Markanda river basin occupying an area of about 1726.3 km2 is a part of the alluvial deposits of the Godavari deltaic plain which is dominated by wave in Godavari river basin in the east coast India. The region is associated with active agricultural activities and makes significant contribution to the country?s agricultural products. Assessment of groundwater quality for irrigation use and hydrochemical evolution of groundwater has been studied. Hydrochemical analysis has been carried out based on concentrations of Ca2+, Mg2+, Na+, K+, Cl-, SO42-, CO3 2- and HCO3 -. Sodium adsorption ratio (SAR), percent sodium (%Na), permeability index (PI) have been studied to evaluate suitability of irrigation use in study area apart from that we generate the spatial maps of pre monsoon and post moon seasons ground water maps with the help of new technologies like Geographical information system (Arc Gis 10.4.1) and Remote sensing.
