A
It has toxic fumes
B
It can leak into our water supply
C
It can’t be processed
D
None of the above
Explanation: 

Detailed explanation-1: -The leachate from Municipal Solid waste landfills is a highly concentrated “chemical soup", so concentrated that small amounts of leachate can pollute large amounts of groundwater, leaving it unsuitable for domestic water use.

Detailed explanation-2: -’Leachate’ is the term for the liquid pollution that seeps through a landfill’s waste pile when it rains or snows. The leachate contains all sorts of harmful chemicals, many of which are known to cause cancer or other serious harm to human health.

Detailed explanation-3: -Landfill leachates contain both dissolved and suspended material and may pose a threat to the environment because of the toxic substances that it carries and contaminates surface water and groundwater.

Detailed explanation-4: -However, other impacts may arise from gas and leachate formation if not well controlled. These impacts include fires and explosions, vegetation damage, unpleasant odors, landfill settlement, groundwater pollution, air pollution and global warming [1].

Detailed explanation-5: -When landfill waste degrades and rain rinses the resulting products out, leachate is formed. The black liquid contains organic and inorganic chemicals, heavy metals as well as pathogens; it can pollute the groundwater and therefore represents a health risk.
