Which of the following is a potential consequence of excessive leachate head?

Excessive leachate head refers to the accumulation of leachate at a landfill site, leading to increased pressure on the underlying material. This pressure can compromise the integrity of the landfill liner and other containment systems, elevating the risk of leachate leakage into the surrounding environment. Leakage poses significant environmental concerns, including groundwater contamination and adverse impacts on nearby ecosystems. Therefore, the increased risk of leakage due to excessive leachate head is a critical issue that landfill managers must address to maintain compliance and protect environmental health. Other options either present outcomes that would not occur as a result of excessive leachate head or suggest improvements that are contrary to the challenges posed by leachate management.
