Clean Up Technology-1

What is the primary focus of clean up technology?

• Removal of pollution from environmental media

• Preventing oil spills

• Creating barriers to contain oil spills

• Using dispersants to spread oil

What are the reasons for oil spills?

• Accidents, unavoidable events, and intentional acts

• Carelessness and weather conditions

• Methane bubbles and earthquakes

• Chemical cleaning and high pressure water

What is the purpose of using oil booms?

• To contain and divert oil spills

• To burn the oil on the water surface

• To use dispersants to spread the oil

• To solidify the spilled oil

What is the downfall of using burning as an oil spill cleanup method?

• Emulsions up to 35% water

• Limited by location and weather

• Inefficiency and high cost

• Loss of resource and release of greenhouse gases

What is the purpose of using dispersants in oil spill cleanup?

• To use microorganisms to break down the oil

• To remove oil from the surface of the water

• To collect the floating oil from the surface of water

• To increase the fluidity of the oil

What is the primary function of skimming in oil spill cleanup?

• To collect the floating oil from the surface of water

• To use microorganisms to break down the oil

• To burn the oil on the water surface

• To solidify the spilled oil

What is the purpose of using vacuum in oil spill cleanup?

• To remove the oil from the surface of the water

• To increase the fluidity of the oil

• To collect the floating oil from the surface of water

• To use microorganisms to break down the oil

What was the cause of the Exxon Valdez oil spill in 1989?

• Oil tanker struck the Bligh Reef

• High pressure methane gas rose up the drilling well

• Gulf War intentional act

• Deepwater Horizon rig explosion

What is the environmental impact of the Exxon Valdez oil spill?

• Estimated up to $500 million losses in fishing

• 20 acres of shoreline still contaminated

• Many species still affected today

• All of the above

What are the cleanup methods deployed for the Deepwater Horizon oil spill in 2010?

• All of the above

• Skimmers accompanied

• Over 1200 miles of boom used

• 1.345 million gallons of dispersants
