What is the main purpose of a leak detection system in landfill leachate containment?

• A. To monitor groundwater levels only
• B. To detect leaks in the leachate containment system
• C. To monitor methane levels in air
• D. To measure waste volume only

Answer: (B)

The main purpose of a leak detection system in landfill leachate containment is to identify any breaches in the containment barriers so leaks can be stopped quickly. This system monitors the integrity of liners and piping (often using interstitial space sensors or other moisture/pressure indicators) to provide an early warning if leachate starts to escape. Detecting leaks early helps prevent contamination of soil, groundwater, and surface water and allows prompt repair before problems escalate. Other options describe monitoring activities that are not the primary function of a leak detection system: groundwater level monitoring checks water resources, methane monitoring assesses air gas, and measuring waste volume is unrelated to detecting containment leaks.
