| India's solid waste production processes along with features have drastically changed as a result of rapid industrialisation, growth, and changes in lifestyle. To look into the impacts of leachate percolate on groundwater, samples of leachate and groundwater were obtained from landfills in Hubli, Karnataka, India. Certain physico-chemical factors and such as the content of heavy metals were measured using groundwater and leachate collections. The current analysis assesses the impact of leachate from Municipal Solid Waste (MSW) dumps on the groundwater quality in Hubli, the Indian state of Karnataka. The physico-chemical properties of leachate and groundwater samples were used to calculate the Leachate Pollutant Index (LPI) and the Water Quality Index (WQI). The leachate pollution index indicates that the leachate from the dump site is highly contaminated. The Hubli municipal solid waste disposal facility appears to be at a mature development stage based on the pH of 7.5 found in the leachate. WQI indicates percentage of groundwater that is good, poor, unsuitable for consumption by humans, and extremely bad is, respectively, 61, 23, 9, and 4%. The main component assessment yielded three basic components (cumulative variance: (80.4%), the first of which showed the largest percentage of variation (36%), suggesting the effects of human as well as natural factors. Hierarchical cluster analysis is used to display three distinct cluster types, types of water in the research location. Because leachate affects the availability of groundwater, it is advisable to construct a carefully built landfill site to avoid leachate from penetrating into the groundwater. | ||
