Assessment Of Ground Water Quality In And Around Thuraiyur Taluk By Using Remote Sensing

Abstract The use of remote sensing and GIS in water monitoring and management has been long recognized. Geographical information system a tool which is used for storing, analyzing and displaying spatial data is also used for investigating ground water quality information. Management of water quality is very important as demand is increases day by day. Water is the most important source for living things on earth which is threatened on it's quality and quantity. pH, DO, COD, BOD, Chloride and Hardness are basic water quality parameter, using standard techniques in the laboratory and compared with the standards. GIS software applied to extract the boundary of the study area, the image was classified to create land use/land cover map. The land use map, geological and soil map are used for correlation between land use, geological formations, and soil types to understand the source of natural pollution that can lower the ground water quality In fact the capability of this technology offers great tools of how the water quality monitoring and managing can be operationalised in our study area. In conclusion remote sensing and GIS technologies coupled with computer modelling are useful tools in providing a solution for future water resources planning and management to government especially in formulating policy related to water quality.
