Our model vs. reality How did we clean up our model oil spill? Which method(s) worked best? How do you think real oil spills are cleaned? What methods might work best?
Cleanup Methods: Booms Definition: used to hold oil in one place so that it is easier to clean. Once the spread of oil is controlled, environmental scientists can choose from three major methods for oil clean-up: –Biological –Chemical –Physical/Mechanical
Cleanup Methods: Biological How is it used: to break down oil into a harmless substance. Examples: fungi, microorganisms They have the potential to provide clean- up in sensitive areas such as shorelines and wetlands without further harming the environment.
Cleanup Methods: Chemical How is it used: to break up or dissolve oil. Examples: soap Another chemical method is simply burning the oil off of the surface. However, because burning and special chemicals might hurt the environment and living organisms, these methods are not the best choice along coastlines or populated areas.
Cleanup Methods: Physical/Mechanical How is it used: to physically remove the oil from the water. Examples: large vacuums, skimmers, and substances to soak up or absorb oil.
