Problems
One of the problems of landfills is pollution of the road from dirty wheels on vehicles when they leave the landfill. To reduce this, wheel washing systems are used to clean the wheels as the vehicle exits the landfill. Poisonous lechate can also leak from the landfill contaminating nearby soil and groundwater. Methane gasses are flammable and explosive if exposed to heat.

“Imagination is a valuable asset in business and she has a sister, Understanding, who also serves. Together they make a splendid team and business problems dissolve and the impossible is accomplished by their ministrations.... Imagination concerning the world’s wants and the individual’s needs should be the Alpha and Omega of self-education.”
—Alice Foote MacDougall (1867–1945)
