Landfill facilities cause the formation of leachate. These waters contain organic and inorganic pollutants. Wastewater contains dissolved chemicals, acidic substances and particles from stored waste. Leachate water is very dangerous for living life, because it seeps into ground and surface waters from the soil, pollutes drinking water sources, and causes diseases to occur and spread. The most important environmental problem is the high pollution load of leachate and the very low biodegradability of organic compounds and heavy metals. It contains high concentrations of COD, BOD, heavy metals, ammonia, inorganic substances as well as durable organic substances such as humic acid. The COD value varies between 150-100000 mg/L.
