deepwater horizon oil spill bioremediation

Clarke, Sanchez, Bonfiles, Escobedo (15 June 2010). [15] 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. Improving Your Non-Technical Skills as a Scientist. [233] Chemicals from the oil and dispersant are believed to be the cause; it is believed that the addition of dispersants made the oil more toxic. The United States federal government estimated the total discharge at 4,900Mbbl (210million USgal; 780,000m3). It smothered corals in oil and chemicals, and disrupted the reproductive cycles of commercial and recreational fish -- including large fish like bluefin tuna. The rig capsized and sank on the morning of April 22, rupturing the riser, through which drilling mud had been injected in order to counteract the upward pressure of oil and natural gas. ASM Connect. By October 2013 it had increased its projection to $9.2billion, saying it could be "significantly higher. Connect With ASM. Now, a team of American scientists led by Terry Hazen have shown that just a. On October 5, 2015, we proposed a comprehensive, integrated, ecosystem restoration plan to address impacts from the spill to the Gulf of Mexico. In May 2010, the bacterial count for the deepwater plume was 55,000 cells/ml and only 27,000 cells/ml outside of the plume. [209] Some estimates are that only 2% of the carcasses of killed mammals have been recovered. The Macondo well is found roughly 41mi (66km) off the Louisiana coast. The time an ecosystem takes to recover from an oil spill depends on its size. [116] The fires released small amounts of toxins, including cancer-causing dioxins. On April 4, 2016, the court approved a settlement with BP for natural resource injuries stemming from the spill. Investigations continue into the public health effects on coastal residents and responders who investigated and cleaned up the mess. The oil slick was comparable in size to naturally occurring oil seeps and was not large enough to pose an immediate threat to wildlife. "[116] Altogether, 1.8410^6USgal (7,000m3) of dispersants were used; of this 771,000USgal (2,920m3) were released at the wellhead. [300][301], Hayward's involvement in Deepwater Horizon has left him a highly controversial public figure. "But tens of thousands of gulf residents still haven't been fully compensated for their losses, and many are struggling to make ends meet. Share sensitive information only on official, secure websites.. On April 20, 2010, the Deepwater Horizon oil rig exploded off the Gulf Coast, killing 11 people and injuring 17. [193] Methane can potentially suffocate marine life and create "dead zones" where oxygen is depleted. The Deepwater Horizon criminal case, also prosecuted under the Clean Water Act, resulted in the largest criminal penalty with a single entity in U.S. history. [115], Containment booms stretching over 4,200,000ft (1,300km) were deployed, either to corral the oil or as barriers to protect marshes, mangroves, shrimp/crab/oyster ranches or other ecologically sensitive areas. This was described as a "sick joke" and "a very serious error of judgement" by Friends of the Earth Scotland. [113] On the most demanding day, 47,849 people were assigned on the response works and over 6,000 Marine vessels, 82 helicopters, and 20 fixed-wing aircraft were involved. The study was published in the April 2016 Diseases of Aquatic Organisms. Pelican eggs contained "petroleum compounds and Corexit". [11][12] The Deepwater Horizon oil spill is regarded as one of the largest environmental disasters in world history. [124][125], The spill was also notable for the volume of Corexit oil dispersant used and for application methods that were "purely experimental. Exceptions for these restrictions were granted on a case-by-case basis dependent on safety issues, operational requirements, weather conditions, and traffic volume. [293][294], In the UK, there was anger at the American press and news outlets for the misuse of the term "British Petroleum" for the company a name which has not been used since British Petroleum merged with the American company Amoco in 1998 to form BP Amoco. How Microbes Clean up Oil: Lessons From the Deepwater Horizon Oil Spill. Natural Resource Damage Assessment (NRDA). [252], A cohort study of almost 2,200 Louisiana women found "high physical/environmental exposure was significantly associated with all 13 of the physical health symptoms surveyed, with the strongest associations for burning in nose, throat or lungs; sore throat; dizziness and wheezing. [234], The United States Department of Health and Human Services set up the GuLF Study in June 2010 in response to these reports. [329] An independent audit of the GCCF, announced by Attorney General Eric Holder, was approved by Senate on 21 October 2011. The first one is increasing the surface area through emulsification. "Bryan Walsh. Bioaugmentation is the inoculation of a relatively small amount of oil-degrading microbes into an affected area. [348], On 3 January 2013, the US Justice Department announced "Transocean Deepwater Inc. has agreed to plead guilty to violating the Clean Water Act and to pay a total of $1.4billion in civil and criminal fines and penalties". [67] 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. [263][264][265] The U.S. Travel Association estimated that the economic impact of the oil spill on tourism across the Gulf Coast over a three-year period could exceed approximately $23billion, in a region that supports over 400,000travel industry jobs generating $34billion in revenue annually. [31] Built by South Korean company Hyundai Heavy Industries[32] and owned by Transocean, the rig operated under the Marshallese flag of convenience, and was chartered to BP from March 2008 to September 2013. [142][143][144] BP reduced Corexit use by 25,689 to 23,250USgal (97,240 to 88,010L) per day, a 9% decline. [270] The ban was lifted in October 2010. The study is run by the National Institute of Environmental Health Sciences, and will last at least five years. Please refer to the appropriate style manual or other sources if you have any questions. An official website of the United States government. When oil from the Deepwater Horizon spill first began washing ashore on Pensacola Municipal Beach in June 2010, populations of sensitive microorganisms, including those that capture sunlight or fix nitrogen from the air, began to decline. Thus, oil that would normally rise to the surface of the water was emulsified into tiny droplets and remained suspended in the water and on the sea floor. [266][267], On 30 April 2010, President Barack Obama ordered the federal government to hold the issuing of new offshore drilling leases and authorized the investigation of 29oil rigs in the Gulf in an effort to determine the cause of the disaster. "[88] On 4 August 2010, BP began pumping cement from the top, sealing that part of the flow channel permanently. On December 15, 2010, the United States filed a complaint in District Court against BP Exploration & Production and several other defendants alleged to be responsible for the spill. were used to cleanup after the Deepwater Horizon oil spill. [242], Workers reported that they were not allowed to use respirators, and that their jobs were threatened if they did. "[342][343] The DOJ also said Transocean, the owner and operator of the Deepwater Horizon rig, was guilty of gross negligence as well. The microbial ecosystem in the Gulf of Mexico may have been primed for oil bioremediation before DWH because of persistent oil seepage in the waters from drilling. Two days later, following a series of pressure tests, it was announced that the well was completely sealed. [342][344], On 14 November 2012, BP and the US Department of Justice reached a settlement. What caused the Deepwater Horizon oil spill? [281], Public opinion polls in the U.S. were generally critical of the way President Obama and the federal government handled the disaster and they were extremely critical of BPs response. The draft plan allocated up to $8.8 billion for restoration from a proposed settlement with BP. In addition, Louisiana reported that lost visitor spending through the end of 2010 totaled $32million, and losses through 2013 were expected to total $153million in this state alone. The Deepwater Horizon accident has brought oil contamination of deep-sea environments to worldwide attention. [63][64][65], That means that over 10010^6USgal (380Ml) (2.4million barrels) remained in the Gulf. In June, 2016 BP announced offsite link that it had come up with its final estimate of the cost for the oil spill: $61.6 billion. [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. There was a microbial shift in the deepwater community as the chemistry and nature of the oil changed. [146], Underwater injection of Corexit into the leak may have created the oil plumes which were discovered below the surface. You may remember the Deepwater Horizon oil spill that happened in 2010, where 3.19 million barrels of oil spilled off the Gulf of Mexico. The oil rig involved in the Deepwater Horizon oil spill was owned and operated by offshore oil-drilling company Transocean and leased by the oil company BP. 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. "[304], The U.S. government rejected offers of cleanup help from Canada, Croatia, France, Germany, Ireland, Mexico, the Netherlands, Norway, Romania, South Korea, Spain, Sweden, the United Kingdom, and the United Nations. "[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. 4 million barrels of oil flowed from the damaged Macondo well over an 87-day period, before it was finally capped on July . For example, genes for hydrocarbon degradation (ex: alkB) are found in uncontaminated samples from the Gulf of Mexico more commonly than in other regions around the world. NIOSH personnel performed air monitoring around cleanup workers at sea, on land, and during the application of Corexit. A massive response ensued to protect beaches, wetlands and estuaries from the spreading oil utilizing skimmer ships, floating booms, controlled burns and 1.8410^6USgal (7,000m3) of oil dispersant. assessedinjuries to natural resourcessuch as fish, bottom-dwelling organisms, nearshore ecosystems, birds, sea turtles, and marine mammalsand lost recreation resulting from the spill. Marine mammals such as dolphins, whales, and seals are also greatly affected by this horrific event. Only about 800,000 barrels had been captured. In the November 2012 resolution of the federal charges against it, BP agreed to plead guilty to 11 felony counts related to the deaths of the 11 workers and paid a $4billion fine. 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. At the same time, organisms able to digest light components of the oil began to multiply, starting the process of converting the pollutant to carbon dioxide . [58] As of December2012[update], 339mi (546km) of coastline remain subject to evaluation and/or cleanup operations. An official website of the United States government. This was to cover all offshore cleanup activities, BP later requested a second NIOSH investigation of onshore cleanup operations. By that time cleanup had cost BP over $14billion. Being hydrophobic compounds that are less dense than seawater, a large amount of such substances will form sheens on the ocean surface. [215] [150] The scientists concluded that "Mixing oil with dispersant increased toxicity to ecosystems" and made the gulf oil spill worse.

The organization Smithsonians National Zoological Park also helped to rescue the remaining marine life. The volume of oil escaping the damaged welloriginally estimated by BP to be about 1,000 barrels per daywas thought by U.S. government officials to have peaked at more than 60,000 barrels per day. Oil cleanup crews worked four days a week on 55mi (89km) of Louisiana shoreline throughout 2013. Pre-oil spill samples are what someone would expect in other beaches of similar location without contamination, which include a variety of diverse organisms that exhibit high level of interactions [5]. oil rig explosion", "BP confirms that Transocean Ltd issued the following statement today", "Offshore Field Development Projects: Macondo", "Search Ends for Missing Oil Rig Workers", "The 11 Workers Who Died During The Deepwater Horizon Explosion", "Rescued oil rig explosion workers arrive to meet families at Kenner hotel", "Coast Guard: Oil rig that exploded has sunk", "US military joins Gulf of Mexico oil spill effort", "White House Struggles as Criticism on Leak Mounts", "Scientists up estimate of leaking Gulf oil", "BP Seeks Gulf Oil Spill Size Ruling From Judge", "New Estimate Puts Gulf Oil Leak at 205 Million Gallons", "New BP Oil Spill Emails Suggest Cover-Up", "The Cover Up: E-mails Show BP Lied to Authorities on The Deepwater Horizon Spill", "Impacts, Perception, and Policy Implications of the BP/Deepwater Horizon Oil and Gas Disaster", "Response To Oil on Gulf Island Beaches Continues", "BP has another setback as oil slick threatens Florida", "Admiral back on the Gulf Coast for spill", "Oil in Lake Pontchartrain stokes worries in New Orleans", "New wave of oil comes ashore west of Mississippi River", "Massive stretches of weathered oil spotted in Gulf of Mexico", "BP Oil Still Ashore One Year After End of Gulf Spill", Deepwater Horizon Oil Spill: Recent Activities and Ongoing Developments, "Environmental effects of the Deepwater Horizon oil spill: A review", "Simulations of underwater plumes of dissolved oil in the Gulf of Mexico", "Nearly 3/4 of BP spill oil gone from Gulf", "Scientists call new gulf spill report 'ludicrous' Oneindia News", "Foul waters, hard lessons from BP oil spill", "Spilled BP oil lingers on Louisiana coast", "Dirty blizzard buried Deepwater Horizon oil", "40,000-Pound Tar Mat Reminds Us the Oil Spill is Not Over", "BP Pulls Out of Gulf Cleanup, Leaving Unanswered Questions Behind", "Robot subs trying to stop Gulf oil leak", "US oil spill 'threatens way of life', governor warns", "Engineers work to place siphon tube at oil spill site", "Update on Gulf of Mexico Oil Spill Response May 24", "Gulf awaits word on latest bid to plug oil leak", "Oil stains beaches and tourists as slick spreads", "Hayward says spill 'never should have happened', "Robots begin work to remove cap from gushing well", "Relief wells and Subsea containment illustration", "Relief wells aim at pipe 18,000 feet deep", "BP's Deepwater Oil Spill Tests End and the Kill Begins, Well Reaches Static Condition", "BP begins pumping cement in next stage of 'static kill', "BP: Blowout preventer that failed to stop Gulf of Mexico oil leak removed from well", "Failed blowout preventer, a key piece of evidence in Gulf oil spill probe, secure on boat", "BP: Cement being pumped in to permanently seal the company's blown-out well in Gulf of Mexico", "Oil could spew until August, officials say", "No end in sight for oil in the Gulf of Mexico", "Oil in new Gulf slick matches that of 2010 spill", "Probe Deepens on New Oil Linked to BP Site", "Scientists: Oil fouling Gulf matches Deepwater Horizon well (photo gallery, video) | al.com", "Coast Guard, BP investigating reports of oil at Deepwater Horizon site", "Coast Guard says oil sheen 16 miles northeast of BP well too dispersed to be recovered", "Sheen at Deepwater Horizon disaster site is BP oil, Coast Guard says", "Coast Guard Says Sheen Near Macondo Matches 2010 BP Spill", "BP finishes latest search for Gulf oil leaks", "Oil may be seeping from Deepwater Horizon site", "Source of new oil sheen near Deepwater Horizon site has been plugged, BP says", "BP Macondo well, Deepwater Horizon wreckage videos released by Coast Guard", "Unknown substance leaking from Deepwater Horizon site", "Mystery 'oil sheen' grows near site of BP Gulf disaster, says researcher", "BP oil spill: US scientist retracts assurances over success of cleanup | Environment", "A Lot of Oil on the Loose, Not So Much to Be Found", "Tar Balls from BP Oil Spill Wash Up on Gulf Beaches", "Florida Keys environmentalists act to protect against BP oil spill summer 2010 | Global Nonviolent Action Database", Containment boom effort comes up short in BP oil spill, "BP oil spill Deepwater Horizon, BP (Business), Oil spills (Environment), Oil and gas companies (Business), Oil (environment), Oil (business), US news, Conservation (Environment), Pollution (Environment), World news, Environment, Business", BP spill response plans severely flawed | MNN Mother Nature Network, "Slosh and Berm: Building Sand Barriers off Louisiana's Coast to Hold Back Oil Spill Has Low Probability of Success", "Are the Sand Berms Really Stopping Oil? When Congress passed the RESTORE Act in 2012, it dedicated 80 percent of all administrative and civil penalties from the responsible parties to ecological and economic recovery efforts in the Gulf. [191] PAHs can harm marine species directly and microbes used to consume the oil can reduce marine oxygen levels. [187] The U.S. It later emerged through documents released by Wikileaks that a similar incident had occurred on a BP-owned rig in the Caspian Sea in September 2008. [359], On 4 September 2014, U.S. District Judge Carl Barbier ruled BP was guilty of gross negligence and willful misconduct. [47][48] The company argued that government figures do not reflect over 810,000bbl (34million USgal; 129,000m3) of oil that was collected or burned before it could enter the Gulf waters. [79] On 3 June 2010, BP removed the damaged drilling riser from the top of the blowout preventer and covered the pipe by the cap which connected it to another riser. [154], Oil was collected from water by using skimmers. [81][324] This fund was set aside for natural resource damages, state and local response costs, and individual compensation, but could not be used for fines or penalties. The addition of an ancillary collection system comprising several devices, also tapped into the BOP, increased the collection rate to approximately 25,000 barrels of oil a day. In addition, the U.S. government temporarily banned BP from new federal contracts over its "lack of business integrity". [370][371], This article is about the oil spill itself. The well is situated in the Macondo Prospect in Mississippi Canyon Block 253 (MC253) of the Gulf of Mexico, in the United States' exclusive economic zone. [155] Due to use of Corexit the oil was too dispersed to collect, according to a spokesperson for shipowner TMT. The report places some of the blame for the accident on BP but also on Halliburton and Transocean. Booms extend 1848in (0.461.22m) above and below the water surface and were effective only in relatively calm and slow-moving waters. [278], On 30 April, President Obama dispatched the Secretaries of the Department of Interior and Homeland Security, as well as the EPA Administrator and NOAA to the Gulf Coast to assess the disaster. [181], On 15 April 2014, BP announced that cleanup along the coast was substantially complete, while the United States Coast Guard work continued using physical barriers such as floating booms, the cleanup workers' objective was to keep the oil from spreading any further. The explosion, which killed 11 men, caused the rig to sink and started a catastrophic oil leak from the well. The British Petroleum oil spill (BP oil spill), also known as the Deepwater Horizon oil spill, is the largest oil spill in the history of the petroleum production industry [11] . The Deepwater Horizon oil spill added roughly 800 million liters of hydrocarbons to the Gulf of Mexico. Post-oil spill samples on the other hand, contain mostly oil-degrading organisms with drastic decrease in diversity. [354], BP and its partners in the oil well, Transocean and Halliburton, went on trial on 25 February 2013 in the United States District Court for the Eastern District of Louisiana in New Orleans to determine payouts and fines under the Clean Water Act and the Natural Resources Damage Assessment. This incident was caused by an explosion of the Deepwater Horizon offshore drilling unit located in the Gulf of Mexico capable of drilling down to 9144 meters deep under water [11] . British pension fund managers (who have large holdings of BP shares and rely upon its dividends) accepted that while BP had to pay compensation for the spill and the environmental damage, they argued that the cost to the company's market value from President Obama's criticism was far outweighing the direct clean-up costs. In summer 2010, approximately 47,000people and 7,000vessels were involved in the project. "Health of Exxon Valdez cleanup workers was never studied". In 2011, one year after the spill, BP agreed to provide up to $1 billion toward early restoration projects in the Gulf of Mexico. JavaScript appears to be disabled on this computer. [10] Reports in early 2012 indicated that the well site was still leaking. A report from the University of Florida said that many locations showed 20% of fish with lesions, while later estimates reached 50%. The remaining 20 percent, or $1.33 billion, went to The Oil Spill Liability Trust Fund, a general government fund established in 1986 to aid in oil spill removal and assessment of the damage they have caused. Three new agencies replaced it, separating the regulation, leasing, and revenue collection responsibilities respectively, among the Bureau of Safety and Environmental Enforcement, the Bureau of Ocean Energy Management, and Office of Natural Resources Revenue. [89], On 3 September 2010, the 300-ton failed blowout preventer was removed from the well and a replacement blowout preventer was installed. [59], It was estimated with plus-or-minus 10% uncertainty that 4.9Mbbl (780,000m3) of oil was released from the well; 4.1Mbbl (650,000m3) of oil went into the Gulf. Transocean plead guilty to criminal charges in January 2013, adding $300 million from criminal fines to funding dedicated to the restoration efforts in the Gulf region and to improve oil spill response training and prevention. [315], The National Commission on the BP Deepwater Horizon Oil Spill and Offshore Drilling released a final report on 5 January 2011. 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. [10], In May 2010, BP admitted they had "discovered things that were broken in the sub-surface" during the "top kill" effort. During this transition period additional $404million in claims were paid. Oil plumes as large as 17 kilometers in diameter were detected just beneath the surface [11] . No flights, except aircraft conducting aerial chemical dispersing operations, or for landing and takeoff, were allowed below 1,000m (3,300ft). [217][218], In 2012, tar balls continued to wash up along the Gulf coast[219][220][221][222] and in 2013, tar balls could still be found in on the Mississippi and Louisiana coasts, along with oil sheens in marshes and signs of severe erosion of coastal islands, brought about by the death of trees and marsh grass from exposure to the oil. After the explosion, oil gushed from the sea floor releasing an estimated 5.84x108 litre of crude oil into the ocean [11] . On September 17 the bottom kill maneuver was successfully executed through the first relief well.
