Bioremediation Methods for Oil Spills

Abstract. The increasing number of marine oil spills asks for effective solutions for the environment. Bioremediation techniques have become a major mechanism for removing oil residues on the affected shorelines. Among the different techniques to enhance natural biodegradation by indigenous microorganisms, seeding of new bacteria and fertilizing the indigenous populations have attracted the most interest. The application of nutrients as nitrogen and phosphorus in the form of fertilizers have shown to be most effective in accelerating the biodegradation process and at the same time to be environmentally safe.

I. Introduction

Since the freighter Pallas caused the worst oil pollution of the tidel shallows in the North Sea last November, thousands of sea birds and probably numerous other species lost their lives in the polluted water. The responsible parties have not yet taken any measures to mitigate the damage, neither have they provided for the prevention of a similar catastrophe in the future. This is especially striking as the first devastating oil spill occurred no less than ten years ago, when the tanker…...

...British Petroleum’s Deep Water Horizon rig explosion infested the Gulf of Mexico, its surrounding coastline, and its inhabitants. The U.S. officials have labeled this incident as an accident. However, preceding events suggest otherwise. A causal argument attempts to demonstrate the believed relationship between actions and certain results. Due to neglect and financial greed, the livelihood of thousands was threatened. Transocean Ltd is the world's largest offshore drilling contractor. It rents floating mobile drill rigs, equipment, and personnel to oil and gas companies. The Deep Water Horizon oilrig was owned by Transocean and leased to BP when the explosion occurred. For three months oil gushed into the Gulf of Mexico. Remote causes are events in the past that link to the future. An example of this in the case of the BP oil spill was the diminished work level of the organization that looks over the proper management of oilrigs. Due to the continual persuasion by profit-driven US corporate and financial elite, US government made it acceptable for the required work level of Mineral Management Service (MMS) to dwindle between 2005 and 2009. As a result, the safety regulations for workers and the environment were left up to drilling organizations. The lack of a constraining factor to stabilize safety resulted in negligence as the drilling companies found it cheaper and more convenient to assume that all operations were going well. As a result, the effectiveness of the rig......

Oil Spills

...Environmental Implications: When oil is leaked, it adversely alters aquatic environments by physically harming mammals and damaging their habitat. Oil is a compound derived from hydrogen and carbon, however, the process in which the compound is formed, enables it to be toxic to plants and wildlife (Cartage, 2012). The accidental spillage of oil is damaging to subsurface and surface organisms through the physical damage that is done to their habitat. The severity of an oil spill is contingent on two factors; whether it is petroleum or non-petroleum based and the general magnitude of the spillage which is typically measured in barrels or U.S. gallons. Oil is destructive to aquatic ecosystems since it interferes with animal membranes, disrupts the regulation of water controlled by fishes and inhibits metabolic activity (Environment Canada, 2011). Typically, wildlife is affected by oil since it gets sticky over time through weathering. This sticky oil induces hypothermia as oil destroys the waterproofing and insulation of their feathers (Australian Maritime Safety Authority, 2012). The ways in which oil spills damage mammals and birds is threefold; through contamination and destruction of food resources. Animals can be affected by oil through inhalation and ingestion. Vapors inherent in oil will denigrate a mammal’s central nervous system, liver, lungs. Additionally, when the oil is ingested, it may unable birds and mammals to properly digest their food as intestinal tracts......

... Gulf Oil Spill Keith Niesen ENV/100 July 22, 2013 Nash Saleh Gulf Oil Spill In 2010 America had a major disasters on its hands the BP oil spill, not only did some people die from this spill, but the oil spill contaminated the Gulf of Mexico. This was a representation of bad technology it also revealed many environmental risks that many people rather ignore. The oil spill also sparked huge outrage as to why this happened and what we must do to prevent another disaster like this. How can we change the way we drill oil and not affect our precious ecosystems and ruin wildlife or are ocean. What is some of the new technology we are using to help with preventing another oil spill from happening? After the oil rig explosion many pollutants were introduced into the air and water. Many of these pollutants were smoke and or hydrocarbon fumes. The water pollutants was the oil and natural gas that was constantly gushing out of the well. The primary pollutants are the smoke and hydrocarbon because they are pollutants that are directly being emitted into the air from a source. There are many concerns with air pollution and scientist have found many chemicals such as alkyl nitrates, methane, hexane and butane compounds the can irritate and burn skin and the eyes and can cause dizziness as well. With all of these samples that have been collected they have not shown levels above government safety regulations (Roosevelt, 2013). Oil pollution we know is dangerous for the environment our...

...American History have we seen the catastrophe that we've seen this year by the BP Oil Spill. The Oil Spill in the Gulf of Mexico is beyond heart breaking. The 1989, Exxon Valdez Oil Spill has been considered the most devastating, human-caused, environmental disaster ever to occur in history, especially towards the Nigerians, since they are still being affected by it. But, even though the Exxon Valdez happened years ago and Nigerians are still in tight situations due to the spill, I believe the BP Oil Spill is just a beginning of a major political conundrum, with lasting consequences similar to what the Nigerians people are experiencing. There are a lot of controversy regarding, who is going to take responsibility for the cleanup for both BP and the Valdez Oil Spill. Some people blame President Obama and some blame Bp for its spill. Blaming the company that is actually in charge of the operation does seem like a logical first step, not to mention, there were many safety warning signs that they ignored to give way to greed. But bear in mind, blaming a president for a disaster caused by a corporation is ridiculous in my opinion. If people are blaming Obama, I think it should be because he didn’t make and veto certain laws and kept an eye on certain factories, if he did, then probably the oil spill would have never happened in the first place. We cannot blame the Spill on Obama completely, but we can blame him for not watching out for......

...   Since April of 2010, BP Oil Company has been working to repair the damages of an oil rig explosion in the Gulf of Mexico. According to Do Something, an environmental website, have reported the death and injury of 28, more than 8,000 animals dead within six months, and 16,000 miles of coastline pollution (11 Facts about the BP Oil Spill). Many accounts blame this catastrophe on BP’s neglect to properly build and maintain machinery. Several clean up workers and fisherman have been affected due to this oil spill (Reed 35). People living near the coast line has been affected due to polluted air and water. Many children had been sick and they had problem breathing fresh air. BP’s ways of “cutting corners” are a point of interest when considering the factors leading to the Deep-water Horizon Oil Spill. There were several issues with this oil spill: professional issues, ethics and new technology issues, legal, regulatory and political, safety issues, and environmental issues. If BP would have taken care of all these issues there had been no oil spill. According to the official federal report, BP’s management cut corners in many areas, especially during the installation of the drill. While drilling the drill pipe got stuck and the engineering had to redesign the parameters but completely cut corners to drill the fastest way possible, which was the start of BP’s problems. Events leading up to the Deepwater Horizon incident led one to question the values and motives of the British......

...English 1301, 9:05 MW P. Schmidt, HLN Paper# 3 Research Paper October 22, 2014 After the oil spill in Gulf of Mexico in 2010, a research by Douglas. B. Inkley shows that scientists are still assessing the effects of the estimated 170 million gallons of oil that flooded into the Gulf after the explosion of BP's Deepwater Horizon oil rig. The effects of oil spills can have wide ranging impacts that are often portrayed by the media as long lasting environmental disasters. Such perceptions are understandable as they are often fuelled by distressing images of oiled animals and other wildlife. More than 8,000 birds, sea turtles, and marine mammals were found injured or dead in the six months after the spill. In the months following the Gulf oil disaster, wildlife managers, rescue crews, scientists and researchers saw many immediate impacts of the oil impacting wildlife. Though oil is no longer readily visible on the surface, it isn’t gone. Scientists have found significant amounts on the Gulf floor, and the oil that has already washed into wetlands and beaches will likely persist for years. We likely will not see the full extent of impacts for many years, which makes creating and implementing successful restoration plans a serious challenge. Here is a list of some animals that were affected by the oil spill: * Sick Dolphins - As part of the official investigation into impacts of the Deepwater Horizon disaster, a team of scientists did comprehensive physicals on dolphins......

Oils Spills

...Oil Spill Environmental Diaster Thursday, April 29, 2010. The massive oil spill off the gulf coast is an environmental disaster. Since it was an oil rig that blew, the oil is leaking from an underwater well, deep in the ocean. It has been hard to calculate how much oil continues to leak, but today it appears to be leaking at the rate of 5,000 barrels a day, not 1,000 as had been thought, and that the spill could reach the coast by Friday. And they don’t have a way to stop the leaking. This is different that the oil that leaked from a grounded ship over the coral reef in Australia this month. That was terrible due to the damage it did to the endangered (and supposedly protected) Great Barrier Reef. But the ship had a limited amount of oil. Since this is a well that is leaking, it seems as if the oil leak could go on and on until they find a way to cap the well. The oil slick is over 80 miles across. The coasts of Louisiana, Mississippi, Alabama, and Florida are preparing for the oil to reach the shore line by as early as Friday. The military has been asked to help, and the Coast Guard are trying to burn the oil in the sea before it comes to the shoreline. Whew! The money made by the oil production could be off set by the loss of income by tourism to these coastal areas. The tension that exists between protecting our environment and increasing our energy sources like oil, coal, and nuclear power, seems to be very problematic. I hope they figure out a way to control this leak....

Bp Oil Spill Disaster

...BP Oil Spill Public Relations Response Introduction BP Oil Spill which is also known as Gulf of Mexico and Deepwater Horizon oil spill is the largest marine oil spill throughout the history which was caused by an explosion on offshore oil platform namely Deepwater Horizon on 20th April, 2010 located at the Mississippi River delta. British Petroleum (BP) was the principal developer of Macondo Prospects oil field where the accident held. The accident occurred when they were closing the oil well for using it in future prospects. BP claimed that on July 15, 2010 they capped the well by stopping the flow of into the Gulf of Mexico in 86 days. Following the hazards of oil spill U.S. Government held British Petroleum responsible for the incident and told the company for all cleanup measure which result in oil spill. BP accepted the responsibility and cleanup costs. According to numerous reports, abnormal amounts of high-pressure methane gas accumulated inside the rig's marine risers, a complex system of tubing that runs between an underwater oil sources. The methane gas traveled through the risers and expanded rapidly, igniting the oil within. The exact cause of the explosion and fire are still under investigation, but according to interviews conducted during BP's internal investigation, several workers aboard the rig reported that a bubble of methane gas had in fact escaped from the well and shot up the drill column, expanding as it burst through several seals and barriers......

Oil Spill

...Oil Spill The disaster that occurred in the Gulf of Mexico on April 20, 2010 was a huge deal to our nation. I'm sure that everyone old enough to understand heard about the oil spill. The spill was very bad, but I believe we got lucky because it could have been even worse than it ended up to be. The oil flowed into the open ocean for over three months, but it was originally thought that it was going to take even longer to stop. A oil spill of that magnitude could severely damage any environment that it was spilt into. The corporation BP took much heat from the government, along with everyone around the country for causing the leak, and not fixing it quick enough. The fact is, once the leak started as it did, it was a very hard problem for them to stop. My paper will cover three elements of this horrible disaster: First, the ecological impact on life in the gulf after the spill, Second, the current economic life of the local communities, and lastly, what is being done to mitigate future consequences. First, obviously the oil spill in the Gulf of Mexico left an ecological impact on life in the gulf, and surrounding areas. On July 15, the leak was stopped by capping the gushing wellhead, after it had released about 4.9 million barrels,^ or 205.8 million gallons of crude oil. That is a whole lot of oil being released, so the impact that it had on the environment was a big one. Actually, it was the largest accidental marine oil spill in history. Obviously the......

... On April 20, 2010 a gas release and explosion happened on the Deepwater Horizon oil rig, famously known as the BP oil spill. It was the largest oil spill in the United States history, eleven people died from the spill and injured 17 others. From the spill there was about more than about 200 million gallons of crude oil that was pumped into the Gulf of Mexico. It happened for almost a total of 87 days, the oil spill started on April 20 until July 15. From underwater cameras it showed that the BP pipe was leaking oil and gas on the ocean floor about 42 miles off the coast of Louisiana. After hearing about the oil spill workers from BP and many government agencies tried to control the spread of the oil to beaches and other coastal ecosystems using floating booms to contain surface oil and chemical oil dispersants to break it down underwater.   [pic]Over a period of those 87 days the wellhead leaked for about 3.19 million barrels. After the release of the oil it cause some floated to the ocean's surface to form oil slicks which expanded more quickly by being pushed by winds. The spill affected coasts of Texas, Louisiana, Mississippi and Florida adding up to total about 16,000 miles. Many investigations were started from the incident, the U.S government faulted BP and the rig operator. Due to many much of the spill coming in contact with wetlands and estuaries affecting many wildlife habitats and fishing and tourism. Being that Louisiana is mostly a tourist......

...Reagan Stehman Mr. Yupanqui ENGL 101-016 9 February 2015 The Devastating Oil Spill of June 3, 2014 On June 3, 2010, an oil rig exploded cracking an underwater oil pipeline which released massive amounts of oil for 3 months straight in the Gulf of Mexico. The oil spill devastated the local wildlife and the surrounding environment. In the picture, there is a brown pelican covered in oil from the spill. The pelican was drenched in oil causing the poor, helpless bird to be unable to fly because the feathers on its wings were clumped together which made it too heavy for the pelican to lift up. The food source that the pelican relied on to survive was most likely destroyed due to the oil spill. When it comes to an oil spill, animals will have swallowed some oil while trying to escape from the monstrosity eventually causing them to slowly die because they ended up poisoning themselves. Not only did the oil spill effect the pelican but also the environment and mankind. Many other animals suffered the same effects as the pelican. The oil polluted the Gulf of Mexico and surrounding waterways both saltwater and freshwater. Oil from the spill covered the beaches along the Gulf of Mexico. With oil-covered beaches, the amount of visitors decreased dramatically. Many stores and restaurants that thrive off of visitors, suffered a great deal of business. A lot of the businesses had to close down or file for bankruptcy because that did not have any money flowing in. Fishermen, who fish......

...clean up oil spills because these oil spills killed hundreds of organisms that lived in the ocean, and if we have another devastating oil spill we’ll know how to clean it up better and faster, so that way animals that live in the ocean won’t die, like the ones that have in the past. So knowing how to clean up after an oil spill is important because if we didn’t then the animals in the sea would die, when they die there won’t be any sea food and the sea food that was there would be filled with oil, dirt, and slime. Who would want to eat food that has oil dirt and slime on it? In the past few centuries, there has been devastating oil spills, like the Exxon Valdez spill on March 23, 1989. The 987 ft. ship was carrying 53,094,510 gallons (1,264,155 barrels) of North Slope crude oil that was bound for Long Beach, California. The Exxon Valdez grounded at Bligh Reef, in Alaska, rupturing eight of its 11 cargo tanks and spewing approximately around 10.8 million gallons of crude oil into Prince William Sound. Another dangerous oil spill was the BP oil spill, in the Gulf of Mexico. On April 20, 2010 an explosion aboard the Deepwater Horizon killed 11 crew members and set off a massive blaze, fire. The rig sank 2 days later into the Gulf of Mexico, unleashing a gush of oil that continued to leak at an alarming rate. Also, in January 1991, Iraq forces released 240 million gallons of crude oil into the Persian Gulf to spoil an amphibious landing by the U.S. Marines. The resulting oil......
