How does landfills affect water?
Landfills, even well engineered ones, can cause air and water pollution. The predominant concern is groundwater and surface water pollution from runoff. After water has filtered through a landfill, it is called leachate. Leachate commonly contains high concentrations of chemicals, heavy metals and microbial life.
Can a landfill contaminate groundwater?
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 landfills can pollute groundwater?
Landfills are supposed to have a protective bottom layer to prevent contaminants from getting into the water. However, if there is no layer or it is cracked, contaminants from the landfill (car battery acid, paint, household cleaners, etc.) can make their way down into the groundwater.
How far should a landfill be from groundwater?
Relevant standards of municipal solid waste landfills (MSWLs) require MSWL and hazardous waste landfills to maintain an isolation distance of 500 and 800 m from the surrounding residents and water bodies.
Is living near a landfill dangerous?
Increases in risk of adverse health effects (low birth weight, birth defects, certain types of cancers) have been reported near individual landfill sites and in some multisite studies, and although biases and confounding factors cannot be excluded as explanations for these findings, they may indicate real risks …
What is a safe distance from a landfill?
Summary: Health is at risk for those who live within five kilometers of a landfill site. According to research published today in the International Journal of Epidemiology, health is at risk for those who live within five kilometres of a landfill site.
What do US citizens throw away the most?
– Food waste and yard trimmings make up more than a quarter (28.2 percent) of the U.S.’ garbage and are organic and easily compostable. – Paper and paperboard, some of which could be composted and the rest of which could be recycled, also make up over a quarter (26.6 percent) of America’s trash.
What happens to landfills after they are no longer active?
But garbage in a landfill does decompose, albeit slowly and in a sealed, oxygen-free environment. Because of the lack of oxygen, bacteria in the waste produce methane gas, which is highly flammable and dangerous if allowed to collect underground. It is also a potent greenhouse gas and contributes to global warming.
What organisms are attracted to landfills?
The food waste found in landfills is attracting birds, mammals and rodents alike to feast on our leftovers.
