What is landfill contamination?

The most serious form of water pollution from landfills is direct leachate contamination, considered a major environmental and human-health hazard. Leachate is a highly odorous black or brown liquid that commonly contains heavy metals, such a lead, and volatile organic compounds or VOCs.

How do landfills prevent groundwater contamination?

Modern sanitary landfills are constructed to prevent leachate contamination of groundwater or surface waters. The bottom of the landfill is lined with impermeable layers, and the leachate is collected and treated before being released to the environment.

How does reducing waste help the environment?

Benefits of Reducing and Reusing

Reduces greenhouse gas emissions that contribute to global climate change. Helps sustain the environment for future generations. Reduces the amount of waste that will need to be recycled or sent to landfills and incinerators. Allows products to be used to their fullest extent.

How can we minimize leachate and landfill gas generation in landfill?

utilization of advanced waste disposal method such as incineration and recycling may be suitable to mitigate the generation of landfill leachate.

How do landfills contaminate water?

Once in the landfill, chemicals can leach into the ground water by means of precipitation and sur- face runoff. New landfills are required to have clay or synthetic liners and leachate (liquid from a landfill containing contaminants) collection sys- tems to protect ground water.

How does landfill affect the environment?

Environmental Impact of Landfills

Along with methane, landfills also produce carbon dioxide and water vapor, and trace amounts of oxygen, nitrogen, hydrogen, and non methane organic compounds. These gases can also contribute to climate change and create smog if left uncontrolled.

How do landfill sites cause pollution?

Greenhouse gas

When organic material such as food scraps and green waste is put in landfill, it is generally compacted down and covered. This removes the oxygen and causes it to break down in an anaerobic process. Eventually this releases methane, a greenhouse gas that is about 25 times more potent than carbon dioxide.

How can landfills affect groundwater?

Groundwater moves slowly and continuously through the open spaces in soil and rock. If a landfill contaminates groundwater, a plume of contamination will occur. Wells in that plume will be contaminated, but other wells, even those close to the landfill, may be unaffected if they are not in the plume.

What are landfills What factors must be kept in mind while planning a landfill?

Explanation: Factors that should be considered when choosing a landfill are topographic relief, location of the water table, amount of precipitation, type of rock and soil and location of the disposal zone in the surface water and groundwater flow systems.

How do landfills affect water quality?

Dumps and landfills are a threat to water supplies when water percolates through waste, picking up a variety of substances such as metals, minerals, organic chemicals, bacteria, viruses, explosives, flammables, and other toxic materials.
