Abstract

This paper is about the study of the Ground water quality analysis using Geographical Information System (GIS) techniques of Kakinada mandal of East Godavari District, Andhra Pradesh, India on 1: 50,000 scale. The Godavari district is also known as the rice bowl of Andhra Pradesh. Godavari River is the second longest river in the country with a length of 1,465 km spreads over an area of about 5,100 sq km on the east coast of India bordering the Bay of Bengal and is a densely populated basin. The study area bounded on its North by Kottapalli; Pithapuram; in the West by Samalkota, Pedapudi, Karapa; in the South by Tallarevu and in the East by Bay of Bengal. The area is flourished with lands of fertile soils, good rain fall and balanced climatic conditions and possesses all the natures hand works of perennial rivers, forests. The sea coast covers 144.4 sq km with made up of Gondawana sandstones. The average annual rain fall is between 110 and 115 centimeters. 20 ground water samples collected at different parts of the study area for Physio-chemical analysis. Using the Inverse Distance Weighted (IDW) interpolation method in ArcGIS software, spatial distribution maps of 12 major water quality parameters are prepared. Water Quality Index (WQI) has been calculated to find the suitability of water for potable purposes. Ground water samples analyzed show quality parameters are pH, Electrical Conductivity, TDS, Fluorides, Chlorides, Calcium, Magnesium, Iron, Turbidity, Magnesium, Alkalinity, Hardness and water zoning using spatial data.
