Coastal Communities Affected
by the Offshore Oil Spill

On April 20, 2010 an explosion occurred at the Deepwater Horizon oil well in the Gulf of Mexico, 50 miles southeast of the coast of Louisiana. Two days later the rig sank and emergency workers reported that oil was being spilled into the Gulf waters. This page is devoted to helping you understand the communities that are threatened by the oil spill.
