deepwater horizon oil spill bioremediation

[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. An investigation of the possible causes of the explosion was launched on 22 April 2010 by the USCG and the Minerals Management Service. One year after the notorious BP Deepwater Horizon oil spill in the Gulf of Mexico and two decades after the Exxon Valdez spill in Prince William Sound off the coast of Alaska the scientific lesson is clear - microbes matter! Responding to the report, Transocean and Halliburton placed all blame on BP. The result could have long-term effects because oil could remain in the food chain for generations. Using Manual Labour. 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). An official website of the United States government. [114], In May 2010, a local native set up a network for people to volunteer their assistance in cleaning up beaches. Booms extend 1848in (0.461.22m) above and below the water surface and were effective only in relatively calm and slow-moving waters. These numbers, coupled with the National Audubon Society scientists' observations of bird colonies and bird mortality well after the acute phase, have led scientists to conclude that more than one million birds ultimately succumbed to the lethal effects of the Gulf oil spill. [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.

The first one is increasing the surface area through emulsification. Phylogenetic Not only was BP required to pay both criminal and civil court ordered penalties of more than $20.8 billion, they funded $500 million in additional research in 2010. [271] On 22 June, a United States federal judge on the United States District Court for the Eastern District of Louisiana Martin Leach-Cross Feldman when ruling in the case Hornbeck Offshore Services LLC v. Salazar, lifted the moratorium finding it too broad, arbitrary and not adequately justified. These traditional techniques are limited in effectiveness and are expensive due to the large area affected by the BP oil spill. [197] A study of insect populations in the coastal marshes affected by the spill also found a significant impact. [286], 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. It uses microorganisms or biological agents to treat oil spills, and soils contaminated 4. . Crude oil is a heterogeneous hydrophobic compound that contains four classes of molecules: saturates, aromatics, asphaltenes, and resins [10] . "The Impact of the BP Oil Spill on Visitor Spending in Louisiana: Revised estimates based on data through 2010 Q4, Prepared for the Louisiana Office of Tourism", "Summary of Information concerning the Ecological and Economic Impacts of the BP Deepwater Horizon Oil Spill Disaster", "BP costs for oil spill response pass $3billion", "Smaller BP's profits down as oil spill trial looms", "Time to scrap BP brand? . Marisa Taylor and Renee Schoof for McClatchy Newspapers, 18 May 2010. [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. [63][64][65], That means that over 10010^6USgal (380Ml) (2.4million barrels) remained in the Gulf. BP officials deny that the disease conditions are related to the spill, saying that dolphin deaths actually began being reported before the BP oil spill. [328], The GCCF and its administrator Feinberg had been criticized about the amount and speed of payments as well as a lack of transparency. [154], Oil was collected from water by using skimmers. Court order granting partial summary judgment of liability for the spill, criminal plea agreement with BP Exploration & Production, Transocean Offshore Deepwater Drilling Inc., Transocean Deepwater Inc., Transocean Holdings LLC, and Triton Asset Leasing GmbH (Transocean), Phase One Trial: Findings of Fact and Conclusions of Law on Gross Negligence and Willful Misconduct, Phase Two Trial: Findings of Fact on Source Control and the Amount of Oil Spilled, Ruling on Maximum Dollars-Per-Barrel Penalty Amount, as Adjusted by the Penalty Inflation Act, $14.9 billion civil settlement with BP Exploration & Production. When did the Deepwater Horizon oil spill happen? [161], Several studies suggest that microbes successfully consumed part of the oil. [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. Omissions? The Deepwater Horizon accident has brought oil contamination of deep-sea environments to worldwide attention. ", EPA slams Jindal's sand berm plan | wwltv.com New Orleans, "How can human hair mop up the oil spill? On 20 April, 2010, an explosion at the Deepwater Horizon rig unleashed the largest oil spill in US history. A study based on samples taken at several beaches in the Gulf of Mexico before and after the BP oil spill showed a drastic change in the microbial community at the locations [5]. [192] The oil contained approximately 40% methane by weight, compared to about 5% found in typical oil deposits. The Deepwater Horizon oil spill began on April 20, 2010, when an explosion damaged the Deepwater Horizon oil rig. Oil cleanup crews worked four days a week on 55mi (89km) of Louisiana shoreline throughout 2013. Fortunately, unl [185], The State of Louisiana was funded by BP to do regular testing of fish, shellfish, water, and sand. On September 17 the bottom kill maneuver was successfully executed through the first relief well. A large scale of bioremediation was deployed during the BP oil spill crisis due to its effectiveness and lower cost [8]. [3] After several failed efforts to contain the flow, the well was declared sealed on 19 September 2010. BP originally estimated a flow rate of 1,000 to 5,000bbl/d (160 to 790m3/d). The Macondo well is found roughly 41mi (66km) off the Louisiana coast. [282], Initially, BP downplayed the incident; its CEO Tony Hayward called the amount of oil and dispersant "relatively tiny" in comparison with the "very big ocean. [138] Because the dispersants were applied at depth, much of the oil never rose to the surface. Corexit EC9500A and Corexit EC9527A were the principal variants. 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. [326][327] Until this more than one million claims of 220,000 individual and business claimants were processed and more than $6.2billion was paid out from the fund. Oil plumes as large as 17 kilometers in diameter were detected just beneath the surface [11] . The conclusion was that BP was partly to blame, as was Transocean, which owned the rig.

BP also agreed to four years of government monitoring of its safety practices and ethics, and the Environmental Protection Agency announced that BP would be temporarily banned from new contracts with the United States government. A .gov website belongs to an official government organization in the United States. The effects of a small spill can take 15 . Regular cleanup patrols were no longer considered justified but cleanup was being conducted on an as-needed basis, in response to public reports. [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. 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. [334] On 21 April 2011, BP issued $40billion worth of lawsuits against rig owner Transocean, cementer Halliburton and blowout preventer manufacturer Cameron. In the case of the Deepwater Horizon oil spill, clean-up workers treated the oil with over 1.4 million gallons of various chemical dispersants. [259] Due to the loss of the market value, BP had dropped from the second to the fourth largest of the four major oil companies by 2013. [204] In March 2012, a definitive link was found between the death of a Gulf coral community and the spill. [10], In May 2010, BP admitted they had "discovered things that were broken in the sub-surface" during the "top kill" effort.

In a New York Times opinion piece, Stephen Teague, staff attorney at the Mississippi Center for Justice, argued that BP had become "increasingly brazen" in "stonewalling payments." [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. On the night of April 20 a surge of natural gas blasted through a concrete core recently installed by contractor Halliburton in order to seal the well for later use. "There was not a culture of safety on that rig," the co-chair said. The second had been intended to serve as a backup and was not completed. [81] The United States government's estimates suggested the cap and other equipment were capturing less than half of the leaking oil. [191][195][196] Signs of an oil-and-dispersant mix were found under the shells of tiny blue crab larvae. Dan Zak for the Washington Post, 3 June 2010. Deepwater Horizon. Washington, DC 20036. [228] A 2015 study of the relative toxicity of oil and dispersants to coral also found that the dispersants were more toxic than the oil. [357][358] According to The Wall Street Journal the U.S. government and Gulf Coast states had prepared an offer to BP for a $16billion settlement. [287][288] CEOs from the top five oil companies all agreed to work harder at improving safety. [citation needed], Prior to the oil spill, on March 31, 2010, Obama ended a ban on oil and gas drilling along the majority of the East Coast of the United States and along the coast of northern Alaska in an effort to win support for an energy and climate bill and to reduce foreign imports of oil and gas. [52] On 10 July, the containment cap was removed to replace it with a better-fitting cap ("Top Hat Number 10"). [364][365][366] Three more BP employees were charged in November 2012. Damage Assessment, Remediation, and Restoration Program. 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]. 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. [116] The fires released small amounts of toxins, including cancer-causing dioxins. The U.S. State Department listed 70 assistance offers from 23 countries, all being initially declined, but later, 8 had been accepted. An oil spill is the release of a liquid petroleum hydrocarbon into the environment, especially the marine ecosystem, due to human activity, and is a form of pollution.The term is usually given to marine oil spills, where oil is released into the ocean or coastal waters, but spills may also occur on land.Oil spills may be due to releases of crude oil from tankers, offshore platforms, drilling . [188][189] Between May and June 2010, the spill waters contained 40 times more polycyclic aromatic hydrocarbons (PAHs) than before the spill. Deepwater Horizon Oil Spill Test Results BioWorld is the greatest of all products tested and 96.1% of the initial concentration of oil was degraded by the end of the study. While the Deepwater Horizon oil spill occurred at a depth of greater than 5,000 feet, deep oil drilling continues in the Gulf of Mexico. Oil sheencould be seen on the surface of the water covering up to 180 000km2 [3] . This process involves investigating the effects of the spill on natural resources and determining the costs to restore them. 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 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. While this technique had worked in shallower water, it failed here when gas combined with cold water to form methane hydrate crystals that blocked the opening at the top of the dome. Now, a team of American scientists led by Terry Hazen have shown that just a. "[296] BP's chief operating officer Doug Suttles contradicted the underwater plume discussion noting, "It may be down to how you define what a plume is here The oil that has been found is in very minute quantities. Under the Clean Water Act fines can be based on a cost per barrel of up to $4,300, at the discretion of the judge. [256][257] The Gulf of Mexico commercial fishing industry was estimated to have lost $247million as a result of postspill fisheries closures. [77] The collected gas was flared and oil stored on board the drillship Discoverer Enterprise. were used to cleanup after the Deepwater Horizon oil spill. Deepwater Horizon Oil Spill Crude oil is shown in the Pacific Ocean offshore of Orange County, California, Oct. 3, 2021. [160], After the well was capped, the cleanup of shore became the main task of the response works. As a result, about $64million of additional payments was made. Brown pelicans and laughing gulls were among the species most affected. [116] Booms were criticized for washing up on the shore with the oil, allowing oil to escape above or below the boom, and for ineffectiveness in more than three- to four-foot (90120cm) waves. GSF Development Driller II started drilling a second relief on 16 May 2010. [227], A 2014 bluefin tuna study in Science found that oil already broken down by wave action and chemical dispersants was more toxic than fresh oil. This is done through the production of proteins and other cellular elements that require a large amount of nitrogen, phosphorous and sulfate. The plan was criticised for its expense and poor results. Construction of two such wells had begun in May. Forensic analysis of the BOP completed the following year determined that a set of massive blades known as blind shear ramsdesigned to slice through the pipe carrying oilhad malfunctioned because the pipe had bent under the pressure of the rising gas and oil. [330] An auditor BDO Consulting found that 7,300 claimants were wrongly denied or underpaid. It is possible to add fertilizers, such as iron, nitrogen and phosphorus, to stimulate the growth of such bacteria, an approach used to speed up microbial activity in the sediment along the Alaska. NOTE: If you need captions, please click the CC button on the player to turn them on.Unprecedented in both scope and nature, the April 20, 2010 Deepwater Hor. Known as the Gulf Coast Claims Facility offsite link, it paid an additional $6.2 billion to more than 220,000 individual and business claimants. The settlement includes: Up to an additional $700 million to respond to natural resource damages unknown at the time of the agreement, and for adaptive management. As many as 8.3 billion oysters were lost. 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. So began an 87-day oil spill that spewed 3.19 million barrels, or nearly 134 million gallons, into the Gulf of Mexico. Please click here to see any active alerts. Updates? website belongs to an official government organization in the United States. [136] 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. [72][73] Next, it placed a 125-tonne (280,000lb) containment dome over the largest leak and piped the oil to a storage vessel. 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. BioWorld Hydrocarbon Treatment was added to weathered oil from the Gulf. [23][24][25] As of 2018[update], cleanup costs, charges and penalties had cost the company more than $65billion. [172][177][178][179][180][181][182] In some cases photographers were granted access only with BP officials escorting them on BP-contracted boats and aircraft. [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. Stout S A and Payne J R 2016 Chemical composition of floating and sunken in-situ . 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. This coalition gained significant influence in the clean-up of the oil spill to try to gain some control over the situation. [172], The FAA denied that BP employees or contractors made decisions on flights and access, saying those decisions were made by the FAA and Coast Guard. With a decrease in microbial diversity and members in these communities, many nutrients cycles are disrupted; this further affects microbes and organisms in general. He apportioned 67% of the blame for the spill to BP, 30% to Transocean, and 3% to Halliburton. [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. Many died from ingesting oil or because it interfered with their ability to regulate their body temperatures. The Deepwater Horizon oil spill added roughly 800 million liters of hydrocarbons to the Gulf of Mexico. [23][59] Oil sector analysts at London-based investment bank Canaccord Genuity noted that a settlement along the lines disclosed would only be a partial resolution of the many claims against BP. Two main types of affected coast were sandy beaches and marshes. environmental disaster, Gulf of Mexico [2010]. Atlas RM, Hazen TC (2011) Oil Biodegradation and bioremediation: a tale of the two worst spills in US history. [241], 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. BP said administration of the 2012 settlement was marred by the fact that people without actual damages could file a claim. The spill area hosts 8,332species, including more than 1,270fish, 604 polychaetes, 218birds, 1,456mollusks, 1,503crustaceans, 4sea turtles and 29marine mammals. 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. BP set up its own private claims program unilaterally in 2010. This oil sheen decreases the amount of sunlight reaching organisms in the water and forms a barrier between the air and water, blocking oxygen and other necessary nutrients from diffusing into the water. U.S. Environmental Protection Agency, Office of Solid Waste and Emergency Response. [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. Appropriate nutrients and dispersants are used in conjunction to help induce growth and increase surface area between oil and microbe by emulsifying the oil respectively [10](refer to Figure 4). It fouled the coasts of Florida, Alabama, Mississippi, Louisiana and Texas and launched a six-year long environmental and legal battle. Oil spill transport and fate models are effective tools which allow a . [147] One plume was 22mi (35km) long, more than 1mi (1,600m) wide and 650ft (200m) deep. Through the Natural Resource Damage Assessment (NRDA)Investigation performed by trustees to identify injuries to natural resources caused by oil spills, hazardous substance releases, and grounding incidents in National Marine Sanctuaries, and plan restoration activities. Corrections? Due to the Deepwater Horizon spill, marine life was suffering. [20] 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.
