rust burn or rot are disposed of improperly such as on the side of the road or in a lot.
There are many environmental problems associated with disposing waste in this manner
such as the potential to damage surface and drinking water and creating breeding grounds
for rats and mosquitoes that can transmit varies diseases. The build up from waste can
also cause levels of methane to raise to the point of combustion.
An early landfill is like an open dump but took the place of open dumps, with no effort to
compact or cover up the waste. Some issues with early landfills are toxins such as acids,
lead, mercury and arsenic along with leachate, and greenhouse gases. Other issues with
early landfills include incomplete decomposition due to the lack of oxygen meaning once
the landfill is closed it will be prone to settling meaning the land will not be able to be
built on. The other issue is that early landfills produce methane which would just seep
upwards and into the atmosphere polluting the air.
Modern landfills are designed to take certain kinds of waste ranging from solid waste to
hazardous waste. Modern landfills have laws and regulation they must follow such as
location restrictions that prevent landfills from being built in wetlands or flood plains.
