About Landfills

A landfill is a site for the disposal of waste materials by burial and is the oldest form of waste treatment. Historically, landfills have been the most common ways to dispose of waste and remains in many places around the world. Many landfills accept uncontaminated soil, green waste, and asphalt loads. Landfills are designed to make sure the waste is isolated from the neighboring environment, such as groundwater, air and rain. It is important to keep waste from surrounding environments to ensure it does not decompose.

The Department of Resources Recycling and Recovery (CalRecycle), along with local enforcement agencies (LEA), regulates the operation of landfills. If facilities do not follow regulations, landfills can harm the environment and public health. Landfills that are not managed correctly can release toxic chemicals in the air and soil, and expose residents to serious health risks.
