Organic matter like yard waste in landfills is a problem primarily because

• there is a high risk of toxic leaching

• it contains bacteria that spreads disease

• as it breaks down it can dissolve the containment

• it produces methane gas

Where would you expect to find the greatest concentration of leachate?

• at the bottom of the landfill

• at the top of the landfill

• throughout the landfill

• leachate is not created in a landfill

Bacteria in landfills perform anaerobic respiration as they decompose materials very slowly. This process creates

• methane

• leachate

• CO2

• oxygen
