Question

Leachate is a coloured liquid that comes out of (A) Compost (B) Aerated lagoon (C) Septic tanks (D) Sanitary landfills

Answer 1

Hint: Leachate is a solvent that contains toxic compounds that can damage our environment. During the process of going through some matter, it is a liquid that removes suspended or soluble solids or some part of substance.

Complete answer:
A leachate is any substance that removes soluble or suspended solids or any other part of the substance it passes through during its passage through it.
Leachate is a term that is often used in the environmental sciences to describe a solvent that has dissolved or entrained environmentally toxic compounds that can then be released into the atmosphere. It's most often associated with the disposal of putrescible or industrial waste.
Leachate is described as any liquid substance that drains from land or stockpiled material and contains substantially elevated concentrations of undesirable material extracted from the material through which it has passed. Leachates are high-strength wastewaters that form as rainwater and moisture percolate into waste in landfills. Humic acids, ammonia nitrogen, heavy metals, xenobiotics, and inorganic salts are among the organic and inorganic pollutants found in leachates. Leachate is a liquid that is generated by composting.
