Abstract

The human activities are constantly adding industrial, domestic and agricultural wastes to the ground water reservoirs at an alarming rate. In the last few decades, rapidly developing technologies, increase in population and urbanization have been witnessing alarmed phenomena all over the world. Anthropogenic activities like generation and indiscriminate disposal of solid wastes and extensive use of fertilizers have resulted in increasing levels of air, water and soil pollution, changing land use patterns, decrease in arable land and other dominant problems. The problems of groundwater quality arise with changing land use patterns and are acute in areas that are densely populated and thickly industrialized, which affect the ground water resources and quality. The present study is aimed at generating physical characters and water quality by using remote sensing and GIS. The thematic map of the study area was prepared from linearly enhanced fused data of IRS-ID PAN and LISS-III merged satellite imagery and Survey Of India (SOI) toposheets on 1:50,000 scale using visual interpretation technique using AutoCad and Arc/Info GIS software forming the spatial database. Groundwater samples were collected from the predetermined sampling locations and analyzed for physico-chemical parameters for the generation of attribute database. The spatial and attribute database thus generated are integrated and maps showing spatial distribution of selected water quality parameters were prepared. Water quality index (WQI) is calculated to assess the suitability of ground water for drinking purpose in the environmental stress areas with respect to water quality . suitable remedial measures are suggested.

Highlights

  • Water is the most ubiquitous material in nature and is the most vital and fascinating of all God’s creation

  • The above investigation reveals that water quality parameter like Hardness, Alkalinity, TDS and Fluoride are beyond the permissible limits and found that the pollution of groundwater is more in the study area

  • Unfit for drinking 8 samples were found with the Water Quality Index (WQI) ranging above 100 in Talaukal,Gundipudi areas.the poor to unfit for drinking samples were observed in areas which are all residential and Agricultural areas. where the domestic waste generated is increasing day by day and using the pesticides in the agricultural lands Improper management of these waste, pesticides may have a greater impact on ground water quality

Summary

INTRODUCTION

Water is the most ubiquitous material in nature and is the most vital and fascinating of all God’s creation. Remote sensing applications have been operationalized in most of the natural resource management themes and at present the trend is on integrated surveys to arrive at sustainable developmental packages Keeping this in view, an attempt is made to evaluate the water quality. Study area The Maripeda Mandal lies geographically between latitudes 17° 20’ 00’’ and 17° 35’ 00’’ and longitudes 79° 45’ 00’’ to 80° 00’ 00’’ is covered in the Survey of India toposheet numbers 56 O/14 and 56 O/15. It is one of the 51 Mandals of Warangal district, in Andhra Pradesh.
