Following the 26 May 2010 hospitalization of seven fishermen that were working in the cleanup crew, BP requested that the National Institute for Occupational Safety and Health perform a Health Hazard Evaluation. The report stated that "whether purposeful or not, many of the decisions that BP, Halliburton, and Transocean made that increased the risk of the Macondo blowout clearly saved those companies significant time (and money). According to NOAA, a cetacean Unusual Mortality Event (UME) has been recognized since before the spill began, NOAA is investigating possible contributing factors to the ongoing UME from the Deepwater Horizon spill, with the possibility of eventual criminal charges being filed if the spill is shown to be connected. The petroleum industry claimed that disasters are infrequent and that this spill was an isolated incident and rejected claims of a loss of industry credibility. Also the United States House Committee on Energy and Commerce conducted a number of hearings, including hearings of Tony Hayward and heads of Anadarko and Mitsui's exploration unit.

Matthew Lysiak and Helen Kennedy, "Dying, dead marine wildlife paint dark, morbid picture of Gulf Coast following oil spill", Daily News (New York), 2 June 2010.Oil continued to be found as far from the Macondo site as the waters off the Florida Panhandle and Tampa Bay, where scientists said the oil and dispersant mixture is embedded in the sand. Slosh and Berm: Building Sand Barriers off Louisiana's Coast to Hold Back Oil Spill Has Low Probability of Success" David Biello in Scientific American 8 June 2010. The report stated that, although the events leading to the sinking of Deepwater Horizon were set into motion by the failure to prevent a well blowout, the investigation revealed numerous systems deficiencies, and acts and omissions by Transocean and its Deepwater Horizon crew, that had an adverse impact on the ability to prevent or limit the magnitude of the disaster. James Diaz, writing for the American Journal of Disaster Medicine, said these ailments appearing in the Gulf reflected those reported after previous oil spills, like the Exxon Valdez.

Biodiversity of the Gulf of Mexico: Applications to the Deep Horizon oil spill" (PDF) (Press release). The two formulations are neither the least toxic, nor the most effective, among EPA's approved dispersants, but BP said it chose to use Corexit because it was available the week of the rig explosion. In 2013, some scientists at the Gulf of Mexico Oil Spill and Ecosystem Science Conference said that as much as one-third of the oil may have mixed with deep ocean sediments, where it risks damage to ecosystems and commercial fisheries. But her favorite part about being in beauty is finding the most effective products, and then sharing that intel with others—because who wants to spend money on stuff that doesn't work? A 2011 analysis conducted by Earthjustice and Toxipedia showed that the dispersant could contain cancer-causing agents, hazardous toxins and endocrine-disrupting chemicals.On 20 May, BP determined that none of the alternative products met all three criteria of availability, non-toxicity and effectiveness. Cetacean Unusual Mortality Event in Northern Gulf of Mexico – Office of Protected Resources – NOAA Fisheries". After one week of testing, BP began to proceed [159] and, by 28 June, had removed 890,000 bbl (141,000 m 3). During the spill response operations, at the request of the Coast Guard, the Federal Aviation Administration (FAA) implemented a 900 sq mi (2,300 km 2) temporary flight restriction zone over the operations area. Pumping continued for eight hours, at the end of which the well was declared to be "in a static condition.

The report also states that a central cause of the blowout was failure of a cement barrier allowing hydrocarbons to flow up the wellbore, through the riser and onto the rig, resulting in the blowout.The trial's first phase was to determine the liability of BP, Transocean, Halliburton, and other companies, and if they acted with gross negligence and willful misconduct. All flights in the operations' area were prohibited except flight authorized by air traffic control; routine flights supporting offshore oil operations; federal, state, local and military flight operations supporting spill response; and air ambulance and law enforcement operations.

They used skimmer boats to remove a majority of the oil and they used sorbents to absorb any remnant of oil like a sponge. The Gulf Coast Claims Facility and the Deepwater Horizon Litigation: Judicial Regulation of Private Compensation Schemes" (PDF).BP released a statement in response to this, saying, that "even prior to the conclusion of the commission's investigation, BP instituted significant changes designed to further strengthen safety and risk management. The manual adds: "Excessive exposure may cause central nervous system effects, nausea, vomiting, anesthetic or narcotic effects". A report from the University of Florida said that many locations showed 20% of fish with lesions, while later estimates reached 50%. Of course, we have a whole range of glossy pantyhose with varying degrees of shine to cover a whole range of circumstances from lunch with the ladies to a dance class. The 2015 film The Runner, directed by Austin Stark and starring Nicolas Cage, is a fictional story of a politician and his family set in the aftermath of the Deepwater Horizon disaster.
