Assessment, management and spatial distribution of ground water for irrigation in Rupnagar district of Punjab (India).

Ground water samples for geo-referenced sites were collected and analyzed for various chemical constituents for assessing their quality for irrigation. These waters were categorized as good and marginal sodic based upon the values of EC and RSC. The ground water quality map of the area was prepared and digitized using GIS software and blockwise area under different categories was commuted, which indicates that Kharar block (46.7 percent of the TGA) has maximum area under marginally sodic water as compared to the Anandpur Sahib block with 8.5 percent of its TGA under marginally sodic waters.
