BP Oil Spill
4/20/2010
“The worst environmental disaster
in US history.” (White House)
Statistics
Deep water well leak
3 months in time
4.9 million barrels = 205.8 million gallons of oil
665 miles of coastline affected
The Clean Up Techniques
•
•
•
•
•
•
Burning
Naturally dispersed
Skimmed by ships
Direct recovery from well
Evaporation and dissolving
Chemical dispersants
Death Toll
• 6,104 Sea Birds
• 609 turtles
• 100 dolphins
Still Under Investigation:
67 Dead Dolphins
35 of them premature or newborn calves
End Result
• BP
–$20,000,000,000 fund for those
affected
–$4,300 per barrel lost + other fines =
$21,000,000,000
Exxon Valdez
March 24,1989
Statistics
• 10.8 million
gallons
• 4.8% of BP
oil spill
• 1,300 miles
of coastline

Death Toll
Death Toll
•2,800 sea otters, 300 harbor seals, 900 bald
eagles, 1,000 harlequin ducks and 250,000
seabirds died in the days following the
disaster.
Death Toll
• Pink salmon embryos continued to be harmed
and killed by oil that remained on stones and
gravel of stream banks through at least 1993.
As a result, the southwestern part of Prince
William Sound lost 1.9 million or 28 percent of
its potential stock of wild pink salmon.
The Cost
2,200,000,000 in fines
1,000,000,000 in payment
300,000,000 to residents and businesses
Questions:
• Why is there such a difference in
environmental impact in these two different
situations?
• Do you agree with the White House on the BP
oil spill being the worst environmental disaster
in history? Explain!
• During the clean up process for each spill, did
the positives help to outweigh the damage?
Explain!
BP vs. Exxon vs. You
• Compare the 2 oil spills with the amount of oil
that would be added to the oceans if everyone
in the US dumped one oil change down the
drain.
Statistics
US population
316,602,287
Vehicles oil capacity
1.25 gallons
Household size
2.63
Vehicles per household
1.9
• If every household in the US dumped one oil
change down the drain on the same day,
calculate how much oil would be “spilled?”
NO calculators!
Compare your answer with that of the two oil
spills discussed in class.
1. Which oil spill would be the most similar to
our produced oil spill?
2. Is this a realistic problem or fiction? Explain!
3. How can we prevent this from happening?
