Leachate from a landfill varies widely in composition depending on the age of the landfill and the type of waste that it contains. [1] [2] It usually contains both dissolved and suspended material. The generation of leachate is caused principally by precipitation percolating through waste deposited in a
If they are above these levels the waste must be taken to a hazardous waste disposal facility and the cost of disposal may increase from about $50.00/ton to as much as $1200.00/ton. As extremely contaminated material is expensive to dispose of, grading is necessary to ensure safe disposal and to avoid paying for disposal of "clean fill."
Double-liner systems are usually found in municipal solid waste landfills, as well all hazardous waste landfills. The first layer is constructed to collect the leachate, while the second layer is engineered to be a leak-detection system to ensure that no contaminants seep into the ground. [3]
Leachate Collection and Removal Systems - sit on top of the composite liner and removes leachate from the landfill for treatment and disposal. [ 5 ] Operating Practices - including the compacting and covering of waste frequently with several inches of soil to help reduce odor; control litter , insects and rodents ; and protect public health .
