emissions, and painting emits VOCs. Fuel leaks also
result in potential air, water, and soil pollution. Glycol-
based materials used in aircraft de-icing can run
off into surface waters or infiltrate groundwater,
depleting oxygen and introducing toxins that
adversely affect life forms in water. Airport cargo
and passenger operations generate large quantities of
solid waste in the forms of paper, wooden pallets,
aluminum, plastic, and glass containers, and consume
large amounts of energy from lighting, heating,
cooling, and computer use.
