What is the outcome when leachate flows to a low point in a collection system?

• A. It is allowed to evaporate
• B. It is pumped or flows by gravity out of the landfill
• C. It remains and causes pressure buildup
• D. It becomes solidified

Answer: (B)

When leachate flows to a low point in a collection system, the correct outcome is that it is pumped or flows by gravity out of the landfill. This process is essential for managing leachate effectively, as it prevents the accumulation of potentially harmful liquids within the landfill. Effective leachate management ensures that the liquid waste is collected and treated appropriately, avoiding any negative environmental impacts. Allowing leachate to flow by gravity or utilizing pumps facilitates its efficient removal, which is crucial in maintaining the structural integrity of the landfill and minimizing the risk of leachate contaminating surrounding soil and groundwater. The other outcomes do not accurately reflect responsible leachate management practices. For instance, allowing leachate to evaporate would not address the potential pollutants it contains, remaining stagnant would lead to pressure buildup and potential leaks, while solidifying leachate is not a feasible option within the context of landfill operations.
