So the garbage does not contaminate the water supply
Landfills must be located far away from groundwater sources to prevent contamination of the water supply. Leachate, a liquid byproduct of decomposing waste in landfills, can contain harmful chemicals that can seep into the groundwater and pollute it. Placing landfills away from groundwater sources helps protect the quality of drinking water and the environment.
Liquids can disappear from landfill sites through a process called leachate. When rainwater or other liquids come into contact with the waste in a landfill, they can dissolve and carry away various chemicals and compounds, creating a toxic liquid known as leachate that can seep into the surrounding soil and water sources. Additionally, some liquids may evaporate over time, especially if the landfill is not properly sealed or covered.
A sanitary landfill retains the dumped material away from the environment until it is "sanitary" or "safe" to release it.
it get hauled away in a truck to the landfill
It goes into a landfill you dick! THANK YOU! :3 XD
As with all garbage on a landfill it will slowly decompose and that takes a really long time. Chemicals will eventually sink down and mix with groundwater. Nutrition and bacterias as well. This can pollute groundwater for generations to come. You ask for 3 threats but I can mainly think of one real threat and that is pollution as in oil or various chemicals. Bacterias can be of an issue if one pump up water close by, but these bacteria will most likely die off and be filtered away by the sand and soil in the ground over a relatively short distance. A third possibility could be radioactivity but this sort of waste-product is not allowed on an ordinary landfill. Finally, if not professionally designed and frequently topped by bulldozing a soil layer on top, contamination is a threat.
Rubbish has many potential routes to follow after collection: * It can be sorted into metals, plastics glass etc. for recycling * It can be incinerated for heat and power * It can be buried in a sanitary landfill
Leaching is the process where water dissolves and carries away minerals or nutrients from the soil or rock as it moves through the groundwater system. This can result in the removal of essential nutrients from the soil, potentially leading to nutrient depletion and water contamination if the leached minerals reach drinking water sources.
because they take a long time to rot and decay
why should you keep diskettes away from magnetic sources
When you throw paper away, it usually ends up in a landfill where it can take years to decompose. This contributes to environmental pollution and waste accumulation. Recycling paper is a more sustainable option as it conserves resources and reduces the amount of waste going to landfills.
After it rains, the water either evaporates, soaks into the ground, runs off into rivers and streams, or collects in puddles. This water can provide hydration for plants and replenish groundwater sources.
