Define the term leachate. Where does it originate and what environmental problems are associated with it?
Leachate is a widely used term in the environmental sciences where it has the specific meaning of a liquid that has dissolved or entrained environmentally harmful substances that may then enter the environment.It is most commonly used in the context of land-filling of putrescible or industrial waste.he primary criterion for design of the leachate system is that all leachate be collected and removed from the landfill at a rate sufficient to prevent an unacceptable hydraulic head occurring at any point over the lining system.
The key environmental problem we face as a result of landfills is groundwater pollution from leachates (the liquid that drains or 'leaches' from a landfill). Although they intended to protect human beings from toxins, due to natural deterioration the protective barriers only delay the inevitable.andfills create a clear and obvious threat to human health as well as a threat to our environment from the hazardous contaminated air emissions emitted from the landfill biodegradation.
10 most extreme places on Earth. Landfill leachate is liquid that moves through or drains from a dump or organized trash collection site. Some leachate exists on its own, usually as a result of natural decomposition.liquids and chemicals that have been discarded also contribute.The biggest source of leachate in most places is rainwater, though.0 most extreme places on Earth.
