What is the difference between a sanitary landfill and a dump?
Traditional landfills, often referred to as “open” or “polluting” dumps, simply contain waste under the ground, potentially allowing a waste by-product called leachate to enter and contaminate groundwater and other water sources. They also attract rodents, insects and other disease-carrying vermin. Other negative effects of open dumps include emission of air pollution, odors and the creation of potential fire hazards. In a sanitary landfill these risks are virtually eliminated, thanks in part to protective liners and monitoring systems that ensure there is no harm being done to the environment.
