Geographic data framework programming is valuable in concentrating hefty metal contamination in streams by gathering information concerning the grouping of HMs in the water, silt, and suspended particles. GIS programming makes it simpler to deal with a voluminous measure of information that is hard to manage on paper. GIS is accordingly helpful in arranging and dynamic. By utilizing GIS we can without much of a stretch update the data that is hard to do in a paper-based arrangement. GIS programming is utilized for digitization of land use map, layers of waste example, HM grouping of the reviewed region, and geochemical guides of the HMs (Ni, Cu, Zn, Cr, Cd, and Pb). GIS helps in getting data in regards to the beginnings of HM contamination in water and its destructive impacts in city regions, farming, and other land units.
