To assess the level of contamination that has occurred or may occur, contaminant movement in soil and water media must be modeled. Additionally, these models aid in the selection of an appropriate remediation approach for the afflicted site. Leachate is a liquid that is created by the penetration of water into landfills and its percolation into waste, as well as by the compression of waste due to its own weight. Contamination causes abrupt changes in the water quality. As a result of natural and human activity, the quality of ground water is always changing. Water pollution is caused by a variety of factors. The main source of organic and inorganic contaminants in ground water is industrial water. Because of the rapid rise of industrialization, a large amount of sewage is disposed of, resulting in significant changes in ground water pollution. The experimental work was carried out according to the American Standard Testing Methods (ASTM, D3987-85 reapproved 200) standard procedures. The work entails sampling contaminated soils from the Shivakote dumpsite at several places and determining heavy metal background concentrations. A study of the level of groundwater contamination in and around the dumpsite would also be conducted. In order to treat them, multiple studies will be conducted by mixing them with various percentages of Fly ash (10-30%) and Bentonite (2-6%) as additives. We can say that the leaching phenomenon on soil and soil mixes spiked with heavy metals lead and nickel was studied using different load ratios of 50mg/kg and 100mg/kg. The leaching percentage for all MP soil and their blends was found to be higher when the load ratio was higher. The subsamples were obtained at 7-day, 28-day, and 45-day curing intervals, respectively. The ability of contaminants to be retained is mostly determined by the curing period, which is unaffected by the action of precipitation.
