  1. The Problem of Oil Spills Post Lab: How do we clean up real oil spills? AIS: ES 2011-2012

  2. Water Pollution: Oil SpillsOil spills are one of the most visible signs of pollution to our environment.  

  3. Sometimes the environment is able to take care of an oil spill by natural processes. However, when a large oil spill occurs, nature needs some assistance in the clean-up process.

  4. Why are oil spills such a problem?

  5. The Exxon Valdez

  6. 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?

  7. 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

  8. 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.

  9. 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.

  10. 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.

  11. Our model vs reality • How was our lab similar to cleaning a real oil spill? • How was it different than cleaning a real oil spill?
