[211][dead link] A peer-reviewed NOAA/BP study disclosed that nearly half the bottlenose dolphins tested in mid-2011 in Barataria Bay, a heavily oiled area, were in guarded or worse condition, "including 17 percent that were not expected to survive". ", EPA slams Jindal's sand berm plan | wwltv.com New Orleans, "How can human hair mop up the oil spill? Post-oil spill samples on the other hand, contain mostly oil-degrading organisms with drastic decrease in diversity. Damage Assessment, Remediation, and Restoration Program. Crude oil is a heterogeneous hydrophobic compound that contains four classes of molecules: saturates, aromatics, asphaltenes, and resins [10] . Environ Sci Technol 45(16):6709-6715. [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. [270] The ban was lifted in October 2010. According to researchers, there is "some evidence it may have caused lesions in fish caught in that area". The Macondo well is found roughly 41mi (66km) off the Louisiana coast. [198] Chemicals from the spill were found in migratory birds as far away as Minnesota. 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. [319][321] It criticized BP for its failure to run a cement bond log test. The spill area hosts 8,332species, including more than 1,270fish, 604 polychaetes, 218birds, 1,456mollusks, 1,503crustaceans, 4sea turtles and 29marine mammals. environmental disaster, Gulf of Mexico [2010]. [248], A 2012 survey of the health effects of the spill on cleanup workers reported "eye, nose and throat irritation; respiratory problems; blood in urine, vomit and rectal bleeding; seizures; nausea and violent vomiting episodes that last for hours; skin irritation, burning and lesions; short-term memory loss and confusion; liver and kidney damage; central nervous system effects and nervous system damage; hypertension; and miscarriages". Mixing dispersants with oil at the wellhead would keep some oil below the surface and in theory, allowing microbes to digest the oil before it reached the surface. [59][109] In addition, a white, milky substance was observed seeping from the wreckage. During this transition period additional $404million in claims were paid. In summer 2010, approximately 47,000people and 7,000vessels were involved in the project. Claims by several research groups that subsurface plumes of dispersed hydrocarbons had been detected in May were initially dismissed by BP and the National Oceanic and Atmospheric Administration (NOAA). Now, a team of American scientists led by Terry Hazen have shown that just a. On 20 April, 2010, an explosion at the Deepwater Horizon rig unleashed the largest oil spill in US history. Corexit EC9500A and Corexit EC9527A were the principal variants. Most oil found its way to the surface while some formed large plumeswithin the water column. GoMRI uses a peer-review process to award grants for independent scientific research conducted primarily at academic institutions, as well as at select for-profit entities. BP originally estimated as part of a Federal Court supervised program offsite link, that those private claims would total about $7.8 billion. Microbial biosurfactants help in bioremediation of hydrophobic compounds by two main mechanisms. Let us know if you have suggestions to improve this article (requires login). [4][49] By early June 2010, oil had washed up on 125mi (201km) of Louisiana's coast and along the Mississippi, Florida, and Alabama coastlines. [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. Observe fireboat responding to crews battling the fire during the Deepwater Horizon oil spill of 2010, See how wire entanglement inside a well bore mitigates the effects of blowout preventer failure in an oil well.

The Deepwater Horizon accident has brought oil contamination of deep-sea environments to worldwide attention. [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. Repeated or excessive exposure may cause injury to red blood cells (hemolysis), kidney or the liver. The manual adds: Excessive exposure may cause central nervous system effects, nausea, vomiting, anesthetic or narcotic effects. It advises, Do not get in eyes, on skin, on clothing, and Wear suitable protective clothing. For Corexit 9500 the manual advised, Do not get in eyes, on skin, on clothing, Avoid breathing vapor, and Wear suitable protective clothing. According to FOIA requests obtained by GAP, neither the protective gear nor the manual were distributed to Gulf oil spill cleanup workers. The gas released caused an enormous underwater explosion that sadly took 11 lives and injured 17 others. [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. [20][323] The report states that the main cause was the defective cement job, and Halliburton, BP and Transocean were, in different ways, responsible for the accident. The scientists said that their findings would most likely apply to other large predator fish and "even to humans, whose developing hearts are in many ways similar." Using Manual Labour. [131] According to BP and federal officials, dispersant use stopped after the cap was in place;[132][133] however, marine toxicologist Riki Ott wrote in an open letter to the EPA that Corexit use continued after that date[134] and a GAP investigation stated that "[a] majority of GAP witnesses cited indications that Corexit was used after [July 2010]."[135]. [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). "[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. 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? How long does oil spill take to clean up? BP set up its own private claims program unilaterally in 2010. A report from the University of Florida said that many locations showed 20% of fish with lesions, while later estimates reached 50%. 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." How Microbes Clean up Oil: Lessons From the Deepwater Horizon Oil Spill. In their statement the DOJ said that some of BP's arguments were "plainly misleading" and that the court should ignore BP's In both oil. [72][73] Next, it placed a 125-tonne (280,000lb) containment dome over the largest leak and piped the oil to a storage vessel. Secondly, increasing the bioavailability (by micelle formation or decreasing interfacial tension and increasing solubility) of hydrophobic water insoluble substrates (14). 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. On August 3 BP conducted a static kill, a procedure in which drilling mud was pumped into the well through the BOP. This was to cover all offshore cleanup activities, BP later requested a second NIOSH investigation of onshore cleanup operations. It also included economic damage claims submitted by the five Gulf states and their local governments. [18][19], Numerous investigations explored the causes of the explosion and record-setting spill. 202-737-3600. service@asmusa.org. 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. [262] NOAA had closed 86,985sqmi (225,290km2), or approximately 36% of Federal waters in the Gulf of Mexico, for commercial fishing causing $2.5billion cost for the fishing industry. Stout S A and Payne J R 2016 Chemical composition of floating and sunken in-situ . Gulf of Mexico Oil Spill: No End in Sight for Eco-Disaster. [191] PAHs can harm marine species directly and microbes used to consume the oil can reduce marine oxygen levels. 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. [138] Because the dispersants were applied at depth, much of the oil never rose to the surface. However, it was verified in June that the plumes were in fact from the Deepwater spill. It set five goals: In 2011, one year after the Deepwater Horizon oil spill, BP agreed to provide up to $1 billion toward early restoration projects in the Gulf of Mexico. [210], In the first birthing season for dolphins after the spill, dead baby dolphins washed up along Mississippi and Alabama shorelines at about 10times the normal number. They used skimmer boats to remove a majority of the oil and they used sorbents to absorb any remnant of oil like a sponge. [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. [369], None of the charges against individuals resulted in any prison time, and no charges were levied against upper level executives. 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. Petroleum is constantly seeping through cracks and vents on the ocean floor; organisms like Pseudomonas thrive in petroleum present environments have evolved mechanisms that would allow them to use the energy rich hydrocarbons as a nutrient source [10]. [156] In mid-June 2010, BP ordered 32machines that separate oil and water, with each machine capable of extracting up to 2,000bbl/d (320m3/d). (1 May 2010). 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. [81] The United States government's estimates suggested the cap and other equipment were capturing less than half of the leaking oil. This coalition gained significant influence in the clean-up of the oil spill to try to gain some control over the situation. Including one-time use sorbent booms, a total of 13,300,000ft (4,100km) of booms were deployed. The disaster had a significant impact on the environment and the local economy, and it highlighted the . By that time cleanup had cost BP over $14billion. [242], Workers reported that they were not allowed to use respirators, and that their jobs were threatened if they did. Oil spill transport and fate models are effective tools which allow a . Blake D A, John V and Lvov Y M 2018 Bacterial proliferation on clay nanotube Pickering emulsions for oil spill bioremediation Colloids Surfaces B Biointerfaces. The paper is titled "Oil biodegradation and bioremediation: A tale of the two worst spills in U. S. history." . [338] On 13 January 2013, Judge Barbier approved a medical-benefits portion of BP's proposed $7.8billion partial settlement. Two weeks after the wellhead was capped on 15 July 2010, the surface oil appeared to have dissipated, while an unknown amount of subsurface oil remained. 97% of payments were made to claimants in the Gulf States. [353], In September 2014, Halliburton agreed to settle a large percentage of legal claims against it by paying $1.1billion into a trust by way of three installments over two years. The U.S. District Court for the Eastern District of Louisiana has established the Deepwater Horizon Oil Spill website for this purpose. [356][357] The second phase scheduled in September 2013 focused on the flow rate of the oil and the third phase scheduled in 2014 was to consider damages. 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. Much research has been done on microbes and their implications in oil spills, but there are still much more to know. 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] . 4 million barrels of oil flowed from the damaged Macondo well over an 87-day period, before it was finally capped on July 15, 2010. Updates? [319] Still another was for not plugging the pipe with cement. [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. [120][121] Critics allege that the decision to pursue the project was political with little scientific input. [146], Underwater injection of Corexit into the leak may have created the oil plumes which were discovered below the surface. However, it was not clear if this deal had been officially proposed to BP and if BP has accepted it. Share sensitive information only on official, secure websites. [292] The council called together a number of federal committees and departments engaged in ocean issues to work with a newly established committee for conservation and resource management. It was largely settled when a Federal District judge approved the largest environmental damage settlement in United States history $20.8 billion on April 4, 2016. [289], The Organization for International Investment, a Washington D.C.-based advocate for overseas investment in the United States, warned that the heated rhetoric was potentially damaging the reputation of British companies with operations in the United States and could spark a wave of U.S. protectionism that would restrict British firms from government contracts, political donations and lobbying. BP was also faced with growing private claim payments estimated at $14.8 billion in October 2016. Secure .gov websites use HTTPS [163][164] David L. Valentine, a professor of microbial geochemistry at UC Santa Barbara, said that the capability of microbes to break down the leaked oil had been greatly exaggerated. That 80 percent resulted in $5.3 billion going to the Gulf Coast Ecosystem Restoration Trust Fund, dedicated to five priorities, commonly called funding buckets: Amount of civil penalties collected from the Clean Water Act and dedicated by the federal RESTORE Act to the Gulf. In addition to the private lawsuits and civil governmental actions, the federal government charged multiple companies and five individuals with federal crimes. [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. Two main types of affected coast were sandy beaches and marshes. Bioremediation was used extensively to combat the devastating effects of the Exxon Valdez oil spill in 1989 and British Petroleum's Deepwater Horizon oil spill in 2010. [10] Reports in early 2012 indicated that the well site was still leaking. Dispersants, Bacteria and Illness in the Gulf, "West Siberian research institute to help clean up Deepwater Horizon spill", BP withholds oil spill facts and government lets it, White House and BP legal wrangling: more damage to collaborative work in disaster response, "Deepwater Horizon NOTAM Overview: Air Traffic Organization, System Operations, Security", "Is BP Stopping Journalists from Observing the Oil Slick? Testing over the past year (2019) reported by GulfSource.org, for the pollutants tested have not produced results.[186]. In April 2012, the Justice Department filed the first criminal charge against Kurt Mix, a BP engineer, for obstructing justice by deleting messages showing that BP knew the flow rate was three times higher than initial claims by the company, and knew that "Top Kill" was unlikely to succeed, but claimed otherwise. . Air concentrations of volatile organic compounds and PAHs never exceeded permissible exposure levels. 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. [137][138] On 19 May, the EPA gave BP 24hours to choose less toxic alternatives to Corexit from the National Contingency Plan Product Schedule, and begin applying them within 72 hours of EPA approval or provide a detailed reasoning why no approved products met the standards. When an attempt to employ a top kill, whereby drilling mud was pumped into the well to stanch the flow of oil, also failed, BP in early June turned to an apparatus called the Lower Marine Riser Package (LMRP) cap. Clean Water Act, RESTORE Act, Oil Pollution Act and criminal statutes lead to $20.8B settlement, largest in U.S. history, Unprecedented funding to support Gulf-wide restoration and research, Major restoration programs funded for next 30 years, NOAA, Department of the Interior and Gulf states developing a 15-year plan, Explosion triggered economic, environmental devastation, and a legal battle, The RESTORE Act results in funding buckets, Settlement to fund a coordinated restoration effort, National Oceanic and Atmospheric Administration, Number of adult oysters lost to the marketplace because of the, What resulted from this one incident was an economic, political, scientific and legal nightmare. Traditional methods of oil spill cleaning include processes such as controlled burns, skimmers, vacuum pumping, low-pressure flush, manual mechanical cleanup, gelling agent, and many more [3], most of which merely remove the hydrocarbon from the affected water or environment and transfers them to another location. [3], From April to mid-July 2010, 411controlled in-situ fires remediated approximately 265,000bbl (11.1million USgal; 42,100m3). [252][253], A study that investigated the health effects among children in Louisiana and Florida living less than 10 miles from the coast found that more than a third of the parents reported physical or mental health symptoms among their children. [105], In October 2012, BP reported that they had found and plugged leaking oil from the failed containment dome, now abandoned about 1,500ft (460m) from the main well. $ 7.8 billion mostly oil-degrading organisms with drastic decrease in diversity of compounds!
