What system is in place to contain and test the leachate?

• A. Double-lined perforated pipes and a leak detection system
• B. Single liner with no testing
• C. Concrete containment with no drainage
• D. Portable containment bags

Answer: (A)

Containing and testing leachate relies on a system that both holds the liquid produced by waste and monitors for leaks. A double-lined setup provides primary and secondary containment, so if the inner liner fails there’s a backup barrier. The perforated pipes in the leachate collection layer gather the liquid and channel it to a drainage or pump system, while the leak detection system continuously watches for breaches, enabling quick detection and response. This combination protects groundwater and surface water and allows regular testing of the leachate to ensure the system is functioning. Why the other ideas don’t fit: a single liner with no testing lacks a secondary barrier and fails to monitor for leaks; concrete containment with no drainage would trap liquids and create structural and environmental problems; portable containment bags aren’t designed for ongoing leachate management or monitoring.
