deepwater horizon oil spill bioremediation

The parents reported "unexplained symptoms among their children, including bleeding ears, nose bleeds, and the early start of menstruation among girls," according to David Abramson, director of Columbia University's National Center for Disaster Preparedness. [197] A study of insect populations in the coastal marshes affected by the spill also found a significant impact. 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.

[85][86][87] On 3 August 2010, first test oil and then drilling mud was pumped at a slow rate of approximately 2bbl (320L) per minute into the well-head. 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." On August 3 BP conducted a static kill, a procedure in which drilling mud was pumped into the well through the BOP. 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. [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). [74] Pumping heavy drilling fluids into the blowout preventer to restrict the flow of oil before sealing it permanently with cement ("top kill") also failed. 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? [257][258] BP's expenditures on the spill included the cost of the spill response, containment, relief well drilling, grants to the Gulf states, claims paid, and federal costs, including fines and penalties. Many low-wage workers in the fishing and service industries, for example, have been seeking compensation for lost wages and jobs for three years. [314], On 9 November 2010, a report by the Oil Spill Commission said that there had been "a rush to completion" on the well and criticised poor management decisions. The study was published in the April 2016 Diseases of Aquatic Organisms. [36][40] The Deepwater Horizon sank on the morning of 22 April 2010. The Deepwater Horizon accident has brought oil contamination of deep-sea environments to worldwide attention. [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. [58] As of December2012[update], 339mi (546km) of coastline remain subject to evaluation and/or cleanup operations. The loss of life and the subsequent pollution of the Gulf of Mexico were the result of poor risk management, lastminute changes to plans, failure to observe and respond to critical indicators, inadequate well control response, and insufficient emergency bridge response training by companies and individuals responsible for drilling at the Macondo well and for the operation of the drilling platform.

Being hydrophobic compounds that are less dense than seawater, a large amount of such substances will form sheens on the ocean surface. To assist with the efforts the captains had to register their ships with the Vessels of Opportunity; however, an issue arose when more boats registered than actually participated in the clean-up efforts only a third of the registered boats. "[246] ProPublica reported that workers were being photographed while working with no protective clothing. "[88] On 4 August 2010, BP began pumping cement from the top, sealing that part of the flow channel permanently. Construction of two such wells had begun in May. 2. Washington, D.C.: U.S. Environmental Protection . The Gulf Coast Claims Facility and the Deepwater Horizon Litigation: Judicial Regulation of Private Compensation Schemes", Independent Evaluation of the Gulf Coast Claims Facility. The study is run by the National Institute of Environmental Health Sciences, and will last at least five years. Bioremediation is a method used to treat water, soil, and subsurface material pollutants through changing environmental conditions to catalyze the growth of microorganisms and reduce the target pollutants 4. [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. The Deepwater Horizon oil spill began on April 20, 2010, when an explosion damaged the Deepwater Horizon oil rig. [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.
