The Deepwater Horizon spill resulted in the largest natural resource damage assessment ever undertaken. A large scale of bioremediation was deployed during the BP oil spill crisis due to its effectiveness and lower cost [8]. [201] In October 2013, Al Jazeera reported that the gulf ecosystem was "in crisis", citing a decline in seafood catches, as well as deformities and lesions found in fish. [318] 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). [320] Halliburton stated that it was acting only upon the orders of BP when it injected the cement into the wall of the well. [123], For a time, a group called Matter of Trust, citing insufficient availability of manufactured oil absorption booms, campaigned to encourage hair salons, dog groomers and sheep farmers to donate hair, fur and wool clippings, stuffed in pantyhose or tights, to help contain oil near impacted shores, a technique dating back to the Exxon Valdez disaster. In March 2014, BP was again allowed to bid for oil and gas leases. Fish and Wildlife Service rescued animals to help with the spill cleanup, although there were many animals found dead. Degraded hydrocarbons mineralize to carbon dioxide, used in biomass or expelled as other hydrocarbon derivatives that are most likely used by other microbes. [141] On 24 May, EPA Administrator Lisa P. Jackson ordered EPA to conduct its own evaluation of alternatives and ordered BP to reduce dispersant use by 75%. Dan Zak for the Washington Post, 3 June 2010. [201] Prior to the spill, approximately 0.1% of Gulf fish had lesions or sores. BP issued a statement strongly disagreeing with the finding, and saying the court's decision would be appealed. The spill occurred in the Gulf of Mexico, off the coast of Louisiana, and resulted in a massive release of oil into the ocean. Credits: U.S. Coast Guard [368] Lastly, Anthony Badalamenti, a Halliburton manager, was charged with instructing two employees to delete data related to Halliburton's cementing job on the oil well. [185], The State of Louisiana was funded by BP to do regular testing of fish, shellfish, water, and sand. The North American Wetlands Conservation Fund received $100 million from the court fines to support projects on wetlands restoration and conservation in the United States, Canada and Mexico. Connect With ASM. The Macondo well is found roughly 41mi (66km) off the Louisiana coast. Initial testing regularly showed detectable levels of dioctyl sodium sulfosuccinate, a chemical used in the clean up. ) or https:// means youve safely connected to the .gov website. The Deepwater Horizon oil spill began on April 20, 2010, when an explosion damaged the Deepwater Horizon oil rig. For the Deep Horizon oil spill, cleanup workers used 1,400,000USgal (5,300,000l; 1,200,000impgal) of various chemical dispersants to further breakdown the oil. Bioaugmentation. "But tens of thousands of gulf residents still haven't been fully compensated for their losses, and many are struggling to make ends meet. [58] As of December2012[update], 339mi (546km) of coastline remain subject to evaluation and/or cleanup operations. Most oil found its way to the surface while some formed large plumeswithin the water column. Under the final consent decree, BP will pay the trustees up to $8.8 billion, the largest recovery of damages ever for injuries to natural resources, to restore the Gulf. The United States Government report, published in September 2011, pointed to defective cement on the well, faulting mostly BP, but also rig operator Transocean and contractor Halliburton. Gerald Baron for Crisisblogger, 8 June 2012. ", "Limits on access to oiled waters, coast frustrates journalists", "It's BP's Oil': Running the Corporate Blockade at Louisiana's Crude-Covered Beaches, "BP's Photo Blockade of the Gulf Oil Spill: Photographers Say BP and Government Officials Are Preventing Them from Documenting the Impact of the Deepwater Horizon Disaster", "Dying, dead marine wildlife paint dark, morbid picture of Gulf Coast following oil spill". [59], On 25 July 2013, Halliburton pleaded guilty to destruction of critical evidence after the oil spill and said it would pay the maximum allowable fine of $200,000 and will be subject to three years of probation. [198][212][213] By 2013, over 650 dolphins had been found stranded in the oil spill area, a four-fold increase over the historical average. The first one is increasing the surface area through emulsification. Tens of billions of dollars in liability and fines were at stake. Though the leak had slowed, it was estimated by a government-commissioned panel of scientists that 4,900,000 barrels of oil had already leaked into the gulf. restoration plan to address impacts from the spill to the Gulf of Mexico, Trustees final comprehensive restoration plan, National Oceanic and Atmospheric Administration, NOAA and the Gulf States Marine Fisheries Commission Partner to Restore Recreational Fish, Rescued from Deepwater Horizon, a Resilient Native Returns to Queen Bess Island, $226 Million in Projects Approved in Gulf Open Ocean Restoration Plan, Two Partners Recommended for Funding to Restore Habitat From Oil and Hazardous Waste Spills, Comments Welcomed on Deepwater Horizon Open Ocean Draft Restoration Plan, Deepwater Horizon Open Ocean Restoration Plan 1 Finalized, Mississippi Acquires Land in Grand Bay with Deepwater Horizon Settlement Funds, NOAA Announces Latest Partnership to Restore Habitats Damaged by Oil and Hazardous Waste, Deepwater Horizon Trustees to Host Two Public Events, July 18 and 19 in Mississippi, A Decade Later: Advances in Oil Spill Science Since Deepwater Horizon, Deepwater Horizon oil spill contributed to high number of Gulf dolphin deaths, https://www.doi.gov/deepwaterhorizon/adminrecord. Many organizations, businesses, and private citizens filed lawsuits for economic, health, and other damages over the spill, and the final $20.8 billion settlement does not cover those. [322] The report concluded that the primary cause of failure was that the blind shear rams failed to fully close and seal due to a portion of drill pipe buckling between the shearing blocks. Phylogenetic As many as 8.3 billion oysters were lost. A bioremediation expert says extreme caution must be used in cleaning up the fragile Gulf Coast ecosystem in the aftermath of the Deepwater Horizon oil spill. The Deepwater Horizon oil spill occurred after a surge of natural gas blasted through a concrete core recently installed to seal an oil well for later use. "There was not a culture of safety on that rig," the co-chair said. "Bryan Walsh. . Thousands of animals were visibly covered in oil. Conferences on this theme occurred at least in 2016 and 2017. Our editors will review what youve submitted and determine whether to revise the article. Early response to the Deepwater Horizon oil rig explosion (USCG). [336] BP originally expected to spend $7.8billion. "[116] Altogether, 1.8410^6USgal (7,000m3) of dispersants were used; of this 771,000USgal (2,920m3) were released at the wellhead. argument that the Gulf region is "undergoing a robust recovery". Review of 10 later hospitalizations found that heat exposure and dehydration were consistent findings but could not establish chemical exposure. [29], The Deepwater Horizon was a 10-year-old[30] semi-submersible, mobile, floating, dynamically positioned drilling rig that could operate in waters up to 10,000ft (3,000m) deep. 4 million barrels of oil flowed from the damaged Macondo well over an 87-day period, before it was finally capped on July . What resulted from this one incident was an economic, political, scientific and legal nightmare. [72][73] Next, it placed a 125-tonne (280,000lb) containment dome over the largest leak and piped the oil to a storage vessel. Bacteria that had adapted to consuming naturally occurring gas and oil seeping from the seabed were thought to have consumed a portion of it. [33][34] BP was the operator and principal developer of the Macondo Prospect with a 65% share, while 25% was owned by Anadarko Petroleum, and 10% by MOEX Offshore 2007, a unit of Mitsui.[35]. The trusteesGovernment officials acting on behalf of the public when there is injury to, destruction of, loss of, or threat to natural resources. "[331], In July 2013, BP made a motion in court to freeze payments on tens of thousands of claims, arguing inter alia that a staff attorney from the Deepwater Horizon Court-Supervised Settlement Program, the program responsible for evaluating compensation claims, had improperly profited from claims filed by a New Orleans law firm. The damage ranged from wetlands and beaches all the way down to the organisms on the sea floor. In addition to the private lawsuits and civil governmental actions, the federal government charged multiple companies and five individuals with federal crimes. These traditional techniques are limited in effectiveness and are expensive due to the large area affected by the BP oil spill. Official websites use .gov The explosion Without any opposing force, oil began to discharge into the gulf. Biostimulation is the adding of nutrients and other growth limiting resources to stimulate the growth of indigenous oil-degrading microbes to increase the rate of remediation. This entailed pumping cement through a channelknown as a relief wellthat paralleled and eventually intersected the original well. "[88] On 4 August 2010, BP began pumping cement from the top, sealing that part of the flow channel permanently. The Deepwater Horizon rig, owned and operated by offshore-oil-drilling company Transocean and leased by oil company BP, was situated in the Macondo oil prospect in the Mississippi Canyon, a valley in the continental shelf. [41] The oil flowed for 87 days. [308] The National Commission on the BP Deepwater Horizon Oil Spill and Offshore Drilling was established on 22 May to "consider the root causes of the disaster and offer options on safety and environmental precautions. Chemical data implied that the substance might be residual oil leaking from the wreckage. [272], On 28 April 2010, the National Energy Board of Canada, which regulates offshore drilling in the Canadian Arctic and along the British Columbia Coast, issued a letter to oil companies asking them to explain their argument against safety rules which require same-season relief wells. [364][365][366] Three more BP employees were charged in November 2012. Oil spill clean upusing oil bloom containments, skimmers, and separators were immediately deployed. [68], In 2013, more than 4,600,000lb (2,100t) of "oiled material" was removed from the Louisiana coast. As oil and gas, shipping, and tourism activities increase, the possibilities of an oil spill also increase. (1 May 2010). [367] David Rainey, BP's former vice-president for exploration in the Gulf of Mexico, was charged with obstructing Congress by misrepresenting the rate that oil was flowing out of the well. "[246] ProPublica reported that workers were being photographed while working with no protective clothing. A limitation of their methodology was that some VOCs may have already evaporated from the oil before they began their investigation. The oil firm alleged failed safety systems and irresponsible behaviour of contractors had led to the explosion, including claims that Halliburton failed to properly use modelling software to analyze safe drilling conditions. The effects of a small spill can take 15 . [350], In January 2014, a panel of the U.S. Fifth Circuit Court of Appeals rejected an effort by BP to curb payment of what it described as "fictitious" and "absurd" claims to a settlement fund for businesses and persons affected by the oil spill. [11][12] The Deepwater Horizon oil spill is regarded as one of the largest environmental disasters in world history. The court ruled that BP hadn't explained "how this court or the district court should identify or even discern the existence of 'claimants that have suffered no cognizable injury. "[237] In July, after testing the blood of BP cleanup workers and residents in Louisiana, Mississippi, Alabama, and Florida for volatile organic compounds, environmental scientist Wilma Subra said she was "finding amounts 5 to 10 times in excess of the 95th percentile"; she said that "the presence of these chemicals in the blood indicates exposure. [369], None of the charges against individuals resulted in any prison time, and no charges were levied against upper level executives. GSF Development Driller II started drilling a second relief on 16 May 2010. According to BP and the USCG, it is "not oil and it's not harmful. [176] The Coast Guard and BP denied having a policy of restricting journalists; they noted that members of the media had been embedded with the authorities and allowed to cover response efforts since the beginning of the effort, with more than 400 embeds aboard boats and aircraft to date. "[281] Some observers suggested that the Obama administration was being overly aggressive in its criticisms, which some BP investors saw as an attempt to deflect criticism of his own handling of the crisis. Articles from Britannica Encyclopedias for elementary and high school students. How long does oil spill take to clean up? [345][346] The plea was accepted by Judge Sarah Vance of the United States District Court for the Eastern District of Louisiana on 31 January 2013. [101][102], The USCG initially said the oil was too dispersed to recover and posed no threat to the coastline,[103] but later warned BP and Transocean that they might be held financially responsible for cleaning up the new oil. In their statement the DOJ said that some of BP's arguments were "plainly misleading" and that the court should ignore BP's [319][321] One was that it had not used a diagnostic tool to test the strength of the cement. "[341], On 31 August 2012, the US Department of Justice (DOJ) filed papers in federal court in New Orleans blaming BP for the Gulf oil spill, describing the spill as an example of "gross negligence and willful misconduct." [170][171], The first video images were released on 12 May, and further video images were released by members of Congress who had been given access to them by BP. Deepwater Horizon oil spill. Another possibility is that it is formation oil escaping from the subsurface, using the Macondo well casing as flow conduit, possibly intersecting a naturally occurring fault, and then following that to escape at the surface some distance from the wellhead. The devastating environmental impacts of the Exxon Valdez spill in 1989 and its media notoriety made it a frequent comparison to the BP Deepwater Horizon spill in the popular press in 2010, even though the nature of the two spills and the environments impacted were vastly different. [340] BP says that it has $9.5billion in assets set aside in a trust to pay the claims, and the settlement will not increase the $37.2billion the company budgeted for spill-related expenses. Deepwater Horizon oil spill, also called Gulf of Mexico oil spill, largest marine oil spill in history, caused by an April 20, 2010, explosion on the Deepwater Horizon oil riglocated in the Gulf of Mexico, approximately 41 miles (66 km) off the coast of Louisianaand its subsequent sinking on April 22. [160], After the well was capped, the cleanup of shore became the main task of the response works. According to EPA's report, the released amount is not enough to pose an added cancer risk to workers and coastal residents, while a second research team concluded that there was only a small added risk. In addition, the U.S. government temporarily banned BP from new federal contracts over its "lack of business integrity". environmental disaster, Gulf of Mexico [2010]. Benthic and highly productive habitats such as marshes and coastal wetlands in the affected areas were contaminated with crude oil and other petroleum by products; they are harmful to many of the organisms that thrive there [2]. In the Deepwater Horizon disaster (2010, Gulf of Mexico), where an oil rig exploded that produced the worst spill in history, bioremediation techniques were applied when it was verified that the spilled oil had bacterial activity. In one example, the U.S. Coast Guard stopped Jean-Michel Cousteau's boat and allowed it to proceed only after the Coast Guard was assured that no journalists were on board. Many large-scale skimmers exceeded the limit. [205][206][207][208] 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. His ruling stated that BP "employees took risks that led to the largest environmental disaster in U.S. history", that the company was "reckless", and determined that several crucial BP decisions were "primarily driven by a desire to save time and money, rather than ensuring that the well was secure." [249], Two years after the spill, a study initiated by the National Institute for Occupational Safety and Health found biomarkers matching the oil from the spill in the bodies of cleanup workers. A final device was created to attach a chamber of larger diameter than the flowing pipe with a flange that bolted to the top of the blowout preventer and a manual valve set to close off the flow once attached. Brown pelicans and laughing gulls were among the species most affected. In October 2011, the United States Department of the Interior's Minerals Management Service was dissolved after it was determined it had exercised poor oversight over the drilling industry. Mac McClelland for Mother Jones, 24 May 2010. The Coast Guard said on Oct. 3 that over 5,300 feet of floating barriers, known as booms, had been deployed and that approximately 3,150 gallons of oil had been recovered from the water. "[295] Later, he drew an outpouring of criticism when he said that the spill was a disruption to Gulf Coast residents and himself adding, "You know, I'd like my life back. [100] Repeated scientific analyses confirmed that the sheen was a chemical match for oil from the Macondo well. The oil well over which it was positioned was located on the seabed 4,993 feet (1,522 metres) below the surface and extended approximately 18,000 feet (5,486 metres) into the rock. [302], In July 2013, Hayward was awarded an honorary degree from Robert Gordon University. Selective pressure placed upon communities of organisms by the large increase of petroleum and other petroleum derivatives selects for the survival of organisms that can use petroleum and derivatives as energy, electron, and or carbon source [5]. 1) The use of dispersants can be harmful to the environment but it is necessary to increase the rate of crude oil degradation by microbes.
