What is remediation of landfill sites?
Generally, the remediation process consists of waste reprofiling; capping, usually with topsoil such as clay or with a geotextile; revegetating, usually with indigenous grass; and, finally, closure. A key element in site reclamation is the transformation of anaerobic to aerobic conditions in the landfilled waste.
Can you build on old landfill sites?

In fact, according to Mike Webster of the environmental charity, Wastewatch: “Historically, municipal landfills were seen as a step forward; a form of landscape remediation whereby you have a hole in the ground created by from open cast mining or quarrying, you fill it up and you can build on it.

Why there is a need of monitoring open dumping sites?
Open dumps are just holes dug to accumulate waste, and no amount of operational activity such as application of compact soil is done. Hence, they pose a greater danger to the environment in terms of bad odors containing harmful contaminants such as methane. 3. Monitoring is a key part of any sanitary landfill.
Why is construction not allowed in a landfill area for 20 years?
It is not safe to construct a building on the landfill or area around it since the breakdown of waste materials in landfills several types of gases are released which are very harmful. So human habitat should be away from landfills to avoid harmful gases, diseases and dirty condition of landfills.
