Leachate Solution - GCSE Chemistry Definition

Leachate solution is a liquid that forms when water passes through a material and picks up small amounts of substances from it, often creating a mix that can be harmful to the environment. For example, when rainwater filters through a landfill, it can collect chemicals and other materials from the waste, becoming leachate. This solution can be dangerous if it leaks into the ground or water supplies because it might contain toxic substances like heavy metals or pollutants. In GCSE Chemistry, understanding leachate is essential because it involves the study of how substances dissolve, interact, and influence our environment.
