Certain daily cover materials can pose environmental risks if they are not properly selected or managed. Some synthetic materials or processed wastes may contain chemicals that could leach into soil or groundwater if they break down over time. Organic materials, like compost or green waste, can generate excess moisture or contribute to uncontrolled decomposition if applied too thickly or unevenly.
Improperly processed construction debris or auto shredder residue might contain metals, plastics, or other contaminants that could affect surrounding soil or water. Weather events, such as heavy rain or strong wind, can also spread lighter materials beyond the landfill boundary, creating litter or pollution offsite. To minimize risks, operators must choose approved materials, monitor their condition regularly, and follow proper application procedures.
