Q. The pollutants which move downward with percolating ground water are called ____:
Answer: Leachates
Notes: Leachate is any liquid that, in passing through matter, extracts solutes, suspended solids or any other component of the material through which it has passed. In older landfills and those with no membrane between the waste and the underlying geology, leachate is free to egress the waste directly into the groundwater. In such cases high concentrations of leachate was often found in nearby springs wells and flushes.
