Characterization of irrigation water of Gurgaon canal command area using geospatial techniques
Author(s): Bhanwar Lal Karela and Ruby Siddiqui
Abstract: There are four major irrigation systems and two minor/ micro irrigation systems available in the state for irrigating the crops. Gurgaon canal flowing through Gurgaon, Rewari and Palwal districts in NCR has been chosen for analysis. Gurgaon canal takes delivery of millions of industrial and domestic waste matters. The objective of the study is to characterize the water quality of Gurgaon canal for irrigation suitability and using geospatial techniques to generate of interpolation maps of individual parameters to find out points of maximum concentration and likelihood of probable agricultural land being affected by pollutant concentration beyond prescribed limit in nearby agricultural land area.
The discharge of untreated industrial effluents into the surface water bodies is a major source of surface as well as groundwater pollution. The analysis of canal water samples collected from different locations in the study area were polluted with industrial effluents and resulted in high concentration of soluble salts and exchangeable cations which may create degradation of soil and groundwater quality while making it unsuitable for irrigation purpose. The Gurgaon canal water at different locations were found high in electrical conductivity, TDS, Bicarbonates and RSC which are the indicators of presence of soluble salts and exchangeable sodium which ultimately create salinity and sodality in the soils and these are also responsible for continuous degradation of soil. The high electrical conductivity value of water samples indicates that the discharge of chemicals as cations and anions were higher in canal water which may be due to the mixing of industrial effluent discharged from industrial areas. The higher values of residual sodium carbonate are due to high concentration of bicarbonate which is responsible to create hardness of soil and water logging conditions in the area due to clogging of soil pores. Use of geospatial techniques help to predict and prevent the further extent of loss and deterioration of soil, plant human health, quality of irrigation and drinking water through satellite image interpretation and other tools. This study is focused to mitigate the deteriorating effect of industrial effluent being mixed with irrigation water which may in turn effect soil health and crop production.
