Answer: A highly toxic liquid formed in landfills
Notes: Recently, environmentalists, wildlife activists, and locals urged the Union Environment Ministry to act against the illegal discharge of toxic leachate into the Aravalli hills. Leachate is a highly toxic liquid formed in municipal landfills. It collects at the bottom of landfills through waste decomposition, water infiltration, and chemical reactions. Its composition depends on waste type, landfill age, rainfall, and temperature. It contains organic pollutants, inorganic compounds, heavy metals, and microbes. Leachate can pollute soil, groundwater, and ecosystems, posing serious health risks. Proper leachate collection and disposal are essential under strict environmental regulations to prevent contamination.
