Cap and cover systems

Cap and cover systems refer to methods used for managing and containing potentially hazardous materials, such as landfill sites or contaminated land. The "cap" is a layer of material placed on top of the site to prevent exposure to contaminants and to manage water infiltration. The "cover" involves the use of vegetation or additional materials to stabilize the area and protect the cap. Together, they help isolate harmful substances from the environment, preventing pollution and ensuring safety for nearby communities while allowing the land to be reused or rehabilitated over time.
