centurymound

Centurymound is a term used to describe a large accumulation of trash, typically from a landfill, that has been capped or covered, often with the intention of allowing it to decompose over an extended period. The "century" aspect refers to the long timescale over which this process is expected to occur, often measured in decades or even centuries. These mounds are characterized by their significant size and the potential environmental considerations associated with them.

The formation of a centurymound is a consequence of waste management practices, particularly in the past when less sophisticated methods of landfilling were employed. As waste decomposes, it can generate gases, such as methane, and leachate, a liquid that can contaminate soil and groundwater if not properly managed. Modern landfill designs incorporate measures to mitigate these risks, including containment systems and gas collection.

The management and monitoring of centurymounds are ongoing concerns for environmental agencies and local authorities. This can involve regular inspections, monitoring of gas emissions, and maintaining the integrity of the capping layers. In some cases, efforts are made to reclaim the land above centurymounds for recreational purposes or other uses, but this requires careful assessment of the site's stability and environmental impact. The long-term stability and potential for future environmental issues are key considerations when dealing with these large, aged waste sites.
