What is a typical task during the expansion of landfill gas systems?

Installing new underground wells is a typical task during the expansion of landfill gas systems because these wells are essential for capturing and managing the gas generated by decomposing organic materials within the landfill. As the landfill matures and expands, the amount of gas produced can increase, necessitating the installation of additional wells to enhance gas extraction and ensure that the system functions efficiently.

This process involves strategic placement to optimize gas collection, reduce odor, and prevent potential environmental hazards associated with gas migration. It is critical for maintaining compliance with environmental regulations and for the overall effectiveness of the gas management system.

The other options involve different processes that, while important for landfill operations, do not specifically pertain to the expansion of gas systems. Sealing off old cells is more about managing completed sections, implementing public education strategies focuses on community engagement, and conducting soil compaction tests pertains to evaluating ground stability rather than gas management.
