The primary purpose of a sanitary landfill is to?

The primary purpose of a sanitary landfill is to dispose of non-hazardous waste efficiently. Sanitary landfills are specifically designed to manage solid waste in a way that minimizes environmental impact and protects public health. They do this by using engineered systems to contain waste, control leachate (the liquid that drains from the waste), and manage gases produced by decomposing material.

These facilities provide a controlled environment where non-hazardous waste can be buried and isolated from the surrounding environment, which helps to prevent contamination of soil and groundwater. By efficiently managing the disposal of large quantities of non-hazardous materials, sanitary landfills play a critical role in waste management and sustainability efforts in communities.

The other options suggest purposes that do not align with the fundamental role of a sanitary landfill. For instance, housing hazardous materials safely is not appropriate for a sanitary landfill since these materials require specialized handling and disposal methods. Encouraging illegal dumping contradicts the regulated and controlled nature of sanitary landfills aimed at managing waste responsibly. Consolidating waste processing into one area could be a byproduct of a landfill's function, but it's not the primary purpose; rather, the focus is on safe and efficient waste disposal.
