What is a leachate solution?
A leachate is any liquid that, in the course of passing through matter, extracts soluble or suspended solids, or any other component of the material through which it has passed.
What is leachate in simple terms?
Leachate is the liquid that drains or ‘leaches’ from a landfill. It varies widely in composition regarding the age of the landfill and the type of waste that it contains. It usually contains both dissolved and suspended material.
What is a leachate sample?
In the environmental sector, the term leachate is used in a variety of contexts. A leachate is defined as any liquid that, by passing through or making contact with matter, extracts soluble and suspended material from the matter. Landfill leachate is a widely used phrase that relates to pore water from a landfill site.
What are the different types of leachate?
The three main categories of conventional landfill leachate treatment technologies are (1) leachate transfer, (2) biological, and (3) physicochemical methods (Renou et al., 2008).
What is leachate how it is formed?
Leachate? “The liquid formed when rain water filters through wastes placed in a landfill. When this liquid comes in contact with buried wastes, it leaches, or draws out, chemicals or constituents from those wastes”.
What is leachate in bioleaching?
Bioleaching. Certain bacteria can break down ores to produce an acidic solution containing copper(II) ions. The solution is called a leachate and the process is called bioleaching . Bioleaching does not need high temperatures, but it produces toxic substances, including sulfuric acid, which damage the environment.
What is leachate and how is it formed?
What is leachate plume?
Leachate seeping from a landfill contaminates the ground water beneath the landfill, and this contaminated ground water is known as a plume. The normal movement of ground water causes the leachate plume to extend away from a landfill, in some cases for many hundreds of meters.
How is leachate made?
Leachate is produced when water filters downward through a landfill, picking up dissolved materials from the decomposing wastes. Depending on characteristics of the landfill and the wastes it contains, the leachate may be relatively harmless or extremely toxic.

What creates leachate and what does it contain?
Leachate is defined as any contaminated liquid that is generated from water percolating through a solid waste disposal site, accumulating contaminants, and moving into subsurface areas. A second source of leachate arises from the high moisture content of certain disposed wastes.
What is the composition of leachate?
Leachate composition is considered in four categories: (I) dissolved organic matter, (2) inorganic macro components, (3) heavy metals, and (4) xenobiotic organic compounds.
What is a leachate in water?
a solution resulting from leaching, as of soluble constituents from soil, landfill, etc., by downward percolating ground water: Leachates in the town’s water supply have been traced to a chemical-waste dump.
What is landfill leachate?
In fact the term “leachate” is so often applied to landfill leachate, both within the waste management industry and outside, that it is easy to forget that leachate is the term used for any liquid produced by the action of “leaching”. Leaching occurs when water percolates through any permeable material.
What is leachate and why is it bad?
Once many people have the answer to their first question of; “What is leachate?”, they realize that it is pretty unpleasant stuff (it smells, can cause pollution etc.). Naturally,they often react by saying they would rather it was not produced.
