Hint:Pollutants from waste dumps have harmful environmental consequences.A landfill site, also known as a tip, dump, refuse dump, garbage dump, or dumping area, is a site for the disposal of waste materials. A leachate is any fluid that removes or any other part of the substance it passes through in the process of passing the matter, soluble or suspended solids.

Complete answer:The waste liquid that has drained into the waste base is stored by the leachate pipes. The infected substance will then be transferred into special vials, which will then be processed for proper storage by a dangerous transport company. Leachate is free to exit the waste and run directly into the groundwater in old waste sites and others without a barrier between the garbage and the underlying geology. High levels of leachate are also found in adjacent springs and flushes in such situations.
Once within the waste disposal, chemicals can leach from precipitation and surface runoff in the groundwater. New waste disposal systems are needed for the protection of groundwater by using tone and synthetic liner and liquid (liquid from waste disposal containing contaminants).
For Municipal Solid Waste (MSW) waste generation, leachate is a big problem and poses a severe threat to surface and groundwater. Many leachate treatment methods exist, including:
Biological aerobic therapy such as airy lagoons and sludge activation.
Biological anaerobic treatment including lagoons and reactors, for example.
Physicochemical treatment, for instance, airstrip, pH adjustment, precipitation chemical, oxidation, and decrease.
Lime, alum, ferric chloride, and soil treatment coagulation.
Advanced technologies including adsorption of carbon, ion exchange.

Hence, the correct answer is option C-both A and B.

Note: Those living five kilometers from a landfill are at risk for health. There was a mistake. The findings showed a clear correlation between sulfide hydrogen (used as a proxy for all contaminants from sites) and death from lung cancer, mortality, and respiratory hospitalization.
