The purpose of leachate and gas monitoring of wells primarily revolves around protecting groundwater on the property’s boundary. Leachate is the liquid that forms when waste breaks down and water filters through that waste, potentially carrying pollutants. Gas monitoring, on the other hand, is concerned with the gases produced by decomposition processes in the landfill.

Monitoring these factors is crucial because they can indicate whether contaminants are migrating from the landfill site into surrounding soil or groundwater. This is particularly important for properties close to water sources, as any leachate or gas leak could pose a significant risk to public health and the environment by contaminating drinking water supplies.

While the other options do relate to aspects of waste management, they do not directly capture the primary aim of leachate and gas monitoring, which is specifically focused on safeguarding groundwater resources.
