Water Quality Assessment of Velacherry Lake Using Remote Sensing and GIS Techniques
Madhumathi T | Sharon Bercy J | Thangaperumal S 
Abstract: Lakes are major upholder of freshwater that supports the environment and its existence. It is evident that many inland water bodies are becoming obsolete with no steps taken towards its protection. A shallow lake in Velachery was tested for its quality with samples collected from 15 points. With urban agglomeration around the lake, it poses a threat to the eco system and its biotic community. Geographical Information System (GIS) which is widely recognized in water quality monitoring in conjunction with remote sensing was used to map the pollution extent of various parameters. It was explicitly seen that the lack of measures for diversion of untreated domestic waste from residential areas combined with dumping of solid discharge and effluents from industries has altered the physio-chemical parameters in an alarming rate.
