Exxon valdez oil spill bioremediation

The Exxon Valdez oil spill occurred in Prince William Sound, Alaska, March 24, 1989, when Exxon Valdez, an oil tanker owned by Exxon Shipping Company, bound for Long Beach, California, struck Prince William Sound's Bligh Reef, 1.5 mi (2.4 km) west of Tatitlek, Alaska, at 12:04 a.m. and spilled 10.8 million US gallons (260,000 bbl) (or 37,000 metric tonnes) of crude oil over the next few days. Statistical analyses of changes in the composition of oil residues remaining on beaches following the Exxon Valdez oil spill in Prince William Sound have demonstrated that bioremediation was effective in accelerating oil removal. Extensive data were obtained in a joint bioremediation monitoring program conducted during the summer of 1990 by the U.S. Environmental Protection Agency (EPA), the State of Alaska, and Exxon.

Exxon Valdez oil spill clean up efforts in the once pristine bays of Prince William Sound. Bioremediation of Exxon Valdez Oil Spill. Based upon results of EPA's research program, the Exxon Corp. will soon begin bioremediation applications on 5800 yards of shoreline on Green and Seal Islands in Prince William Sound, Alaska. The Exxon Valdez Spill in Prince William Sound. On March 24, 1989 the oil tanker Exxon Valdez ran aground on Bligh Reef in Prince William Sound, AK, spilling an estimated 11 million gallons (42 million liters) of crude oil that spread as a surface slick(1) (Figure ​(Figure1).1). In this article we consider what we have learned from the Exxon Valdez oil spill (EVOS) in terms of when bioremediation should be considered and what it can accomplish. We present data on the state of oiling of Prince William Sound shorelines 18 years after the spill, including the concentration and composition of subsurface oil residues (SSOR) sampled by systematic shoreline surveys conducted between 2002 and 2007. A new interpretative technique used following the 1989 Exxon Valdez spill in Alaska shows that fertilizer applications significantly increased rates of oil biodegradation. Biodegradation rates depended mainly on the concentration of nitrogen within the shoreline, the oil loading,

According to studies done by the EPA and Exxon following the Exxon Valdez spill in 1989, initial bioremediation rates can be as high as 1.2% per day. However, as hydrocarbon concentrations decreased, bioremediation rates dropped accordingly irrelevant of further fertilizer application, suggesting that it is most effective with high concentrations of oil. The Exxon Valdez spill, in particular, gave researchers a rare opportunity to evaluate the feasibility of using bio- remediation as an oil spill countermeasure. This OTA background paper evaluates the current state of knowledge and assesses the The Exxon Valdez oil spill was a manmade disaster that occurred when Exxon Valdez, an oil tanker owned by the Exxon Shipping Company, spilled 11 million gallons of crude oil into Alaska’s Prince The Exxon Valdez oil spill in 1989 in Prince William Sound, Alaska, was the genesis of global attention to this process. Since 1989, bioremediation has become a technology that is discussed, applied, and considered in many different circumstances. Bioremediation was used extensively to combat the devastating effects of the Exxon Valdez oil spill in 1989 and BP’s Deepwater Horizon oil spill in 2010. In both oil spills, microorganisms were used to consume petroleum hydrocarbons and played a significant role in reducing the environmental impact. Clean Up of the Exxon Valdez Spill. By Patrick Shinnefield. In March of 1989 the Exxon Valdez, loaded with 1,264,155 barrels of North Slope crude oil ran aground on Bligh Reef in the northeastern portion of Prince William Sound. About one fifth of the total cargo, 1 1.2 million gallons, spilled into the sea.

It was the worst oil spill in U.S. history until the Deepwater Horizon oil spill in 2010. Exxon Valdez On March 24, 1989, shortly after midnight, the oil tanker Exxon Valdez struck Bligh Reef in Prince William Sound, Alaska, spilling more than 11 million gallons of crude oil. The spill was the largest in U.S. history and tested the abilities of local, national, and industrial organizations to prepare for, and respond to, a disaster of such magnitude. How much oil was spilled? Approximately 11 million gallons or 257,000 barrels or 35,000 metric tonnes (38,800 short tons). Picture the swimming pool at your school or in your community. The amount of spilled oil is roughly equivalent to 17 olympic-sized swimming pools. How much oil was the Exxon Valdez carrying? 53,094,510 gallons or 1,264,155 barrels The Exxon Valdez oil spill occurred in Prince William Sound, Alaska, March 24, 1989, when Exxon Valdez, an oil tanker owned by Exxon Shipping Company, bound for Long Beach, California, struck Prince William Sound's Bligh Reef, 1.5 mi (2.4 km) west of Tatitlek, Alaska, at 12:04 a.m. and spilled 10.8 million US gallons (260,000 bbl) (or 37,000 metric tonnes) of crude oil over the next few days.
