In August the company filed suit against the EPA in Texas federal court, asking that the ban be lifted. The effect of the microscopic oil droplets on the ecosystem was unknown, though their presence, along with that of a layer of oil several inches thick discovered on portions of the seafloor in September, cast doubt on earlier predictions about the speed with which the discharged oil would dissipate.
Legal action Charges, settlements, and penalties A formal civil and criminal investigation into the spill was initiated in June by the U.
The deal was approved in January A spokesperson for the U. A modeling study released in February suggested that the activity of oil-eating microbes was negatively affected by blooms of other species of microbes that preferred to feed on the dispersants.
Few travelers were willing to face the prospect of petroleum-sullied beaches, leaving those dependent on tourism struggling to supplement their incomes. The ruling on the second phase, announced in Januaryset the legal amount of oil for which the involved parties would be liable at 3.
Deepwater Horizon oil spill: Found as deep as 4, feet below the surface, corals near the blowout showed signs of tissue damage and were covered by an unknown brown substance, later identified as oil from the spill.

Aftermath and impact Economic prospects in the Gulf Coast states were dire, as the spill affected many of the industries upon which residents depended. Eggs containing traces of contaminants were found in Iowa and Illinois as well.
Disasters of epic proportions. Researchers are developing new dispersants that cause less environmental damage for the next spill. The impact of the spill on fish communities is still largely unknown.
Five years after the spill some scientists believe that injecting dispersants directly at the wellhead may not have done much to help reduce the size of the oil droplets. Tests also determined that oil and dispersants were fatal to rotifers, microorganisms crucial to the gulf food web.
Coral larvae, which are initially mobile, attached to mature corals at much-reduced rates following exposure to the substances. The drilling moratorium, initially set to expire in Novemberwas lifted in mid-October, though new drilling permits were not issued until February of the subsequent year following mounting government and industry pressure to increase domestic oil production.
Booms to corral portions of the slick were deployedand the contained oil was then siphoned off or burned. It was not lifted until March ; the company successfully bid on 24 federal contracts later that month. A spokesperson for the U.
It was hoped that extensive revisions to offshore-drilling regulations, prompted by the spill and issued in Aprilwould mitigate the likelihood of future disasters. Oil continued to wash ashore in many areas, and much of it could not be removed, either because of logistical reasons—mats of submerged oil and organic matter collected in tidal zones that were difficult to reach—or because cleaning it up would inflict greater harm on the ecosystem.
By late some 1, turtles had been found dead. Various risks were identified and evaluated, in particular that an increase in microbial activity might reduce subsea oxygen levels, threatening fish and other animals.
A study showed that the larvae of commercially important fish species, including tuna, likely developed heart defects after exposure to polycyclic aromatic hydrocarbons PAHs from the oil.
In addition to large oil spills such as this, non-point sources of pollution continue to threaten our ocean ecosystem.
These sources can be as significant as the Deepwater Horizon/BP spill and are more directly linked to individual behaviors. Deepwater Horizon oil spill ofalso called Gulf of Mexico oil spill oflargest marine oil spill in history, caused by an April 20,explosion on the Deepwater Horizon oil rig—located in the Gulf of Mexico, approximately 41 miles (66 km) off the coast of Louisiana—and its subsequent sinking on April In the BP Oil Spill, more than million gallons of crude oil was pumped into the Gulf of Mexico for a total of 87 days, making it the biggest oil spill in U.S.
