What is the function of a leachate collection system?

• A. To reduce the volume of solid waste
• B. To capture and remove leachate from landfill sites
• C. To manage air quality
• D. To generate energy from waste

Answer: (B)

The function of a leachate collection system is primarily to capture and remove leachate from landfill sites. Leachate is a liquid that forms when water seeps through landfill materials, becoming contaminated with various organic and inorganic substances from decomposing waste. This system ensures that the leachate is collected before it can contaminate surrounding soil and groundwater, thus protecting the environment and human health.

By effectively managing the leachate, the collection system helps prevent seepage into the surrounding ecosystem, which could lead to significant environmental damage and potential health threats due to the leachate's toxic properties. The proper handling of leachate also aids in adhering to regulatory requirements regarding landfill management, ultimately promoting sustainable waste management practices.

Other options, while related to waste management, do not describe the specific function of a leachate collection system. Reducing the volume of solid waste pertains to waste minimization strategies, air quality management involves controlling emissions and pollutants from various sources, and generating energy from waste relates to converting waste materials into usable energy, none of which address the critical need for leachate management in landfill operations.
