To leach out means to pass water through a mass of solid causing the soluble parts of the solid to pass into solution. (For instance, heavy rain can leach nitrates out of soil). Thus a leachate would be the water and its dissolved solids after it has passed through the solid.
To understand leachate, think of a teabag, water dissolves the organic flavour out of the tea leaves inside and becomes tea. Similarly when water comes in contact with the material in a dump or contaminated soil it dissolves part of the contamination and carries it along. The water and contaminant is leachate.

leachate -- very hard to find in dictionary and hardly general knowledge!!
Solution A is highly concentrated than solution B.

The term for the liquid at the bottom of a landfill is "leachate". It consists of anything soluble in water or any solvents in the waste. Leachate is very nasty stuff and the goal of landfill design is ways to minimize the entry of water to reduce leachate generation. It is typically acidic and contains metals in solution, along with organics of all types.
By using a liner to keep leachate in place.
The Environment Agency has information on treatment for leachate on their website. On their website you can find out how to make an environmental permitting application for leachate treatment activities and see the guidance available.
Yes, leachate can have harmful effects on nature. When it is released into the environment, leachate can contaminate soil, surface water, and groundwater with pollutants, such as heavy metals and harmful chemicals, posing risks to ecosystems and wildlife. Proper management and control of leachate are essential to minimize its impact on nature.
leachate comes from landfills; it leaks from landfills and pollutes waters and i think it is very bad so dont let landfills pollute any more because leachate is bad for us.

Leachate could run off into streams or lakes, or could trickle down into the groundwater below the dump.

In general, landfill leachate does not serve a meaningful purpose and is more of a hindrance than anything else. It can be possible to extract clean water from it however.
