Oil doesn’t dissolve in water. It lasts a long time and sticks to
everything from beach sand to bird feathers. Oil and petroleum
products are toxic to people, wildlife, and plants. One quart of
motor oil can pollute 250,000 gallons of water, and one gallon
of gasoline can pollute 750,000 gallons of water! Oil that leaks
from our cars onto roads and driveways is washed into storm
drains, and then usually flows directly into a lake or stream.
Used motor oil is the largest single source of oil pollution in
lakes, streams, and rivers. Americans spill 180 million gallons
of used oil each year into the nation’s waters. This is 16 times
the amount spilled by the Exxon Valdez in Alaska!
