Twenty five years ago on March 24, more than 11 million gallons of crude oil spilled into Alaska’s Prince William Sound after Capt. Joseph Hazelwood ran the Exxon Valdez into Bligh Reef.

Deepwater Horizon Oil Spill

On July 30, 1989, four months after it ran aground in Alaska’s Prince William Sound and caused the then-largest oil spill in U.S. waters, the crippled Exxon Valdez entered dry dock at National Steel and Shipbuilding in San Diego—its original birthplace.

The National Transportation Safety Board reported Thursday that the captain of the Exxon Valdez was legally drunk when he was tested some 10 hours after his tanker hit a reef last week, causing the worst oil spill in U.S. history.

Exxon Valdez oil spill costs exceeded $7 billion Cleanup alone cost in the region of US $2.5 billion and total costs (including fines, penalties and claims settlements) have, at times been estimated at as much as US $7 billion.”

The Exxon Valdez is significant because it was an oil tanker that caused one of the worst oil spills in U.S. history, leading to the building of double-hulled ships.

Wildlife suffered Photos of oiled seabirds and otters have become spill clichés but animals were indeed hurt by the Exxon Valdez disaster. An estimated 250,000 seabirds, 2,800 sea otters and 300 harbor seals were killed in the immediate aftermath, according to the National Oceanic and Atmospheric Administration (NOAA).

It decimated salmon fisheries. It killed hundreds of harbor seals and thousands of sea otters. It wiped out hundreds of thousands of sea birds, and billions of salmon and herring eggs. The “highly unlikely” devastated 28 types of animals, from mussels and clams to salmon, bald eagles, cormorants, and killer whales.

A new study released today into the effects of the 1989 Exxon Valdez oil spill in Alaska shows that embryonic salmon and herring exposed to very low levels of crude oil can develop hidden heart defects that compromise their later survival, indicating that the spill may have had much greater impacts on spawning fish …

On March 24, 1989, the Exxon Valdez ran aground in northern Prince William Sound, spilling 42 million liters of crude oil and contaminating 1,990 kilometers of shoreline. Some 2,000 sea otters, 302 harbor seals and about 250,000 seabirds died in the days immediately following the spill.

The U.S. Congress enacted the Oil Pollution Act of 1990 (OPA) to streamline and strengthen the Environmental Protection Agency’s (EPA) power to prevent oil spills. It was passed as an amendment to the Clean Water Act of 1972 following the Exxon Valdez oil spill of 1989.

Why do oil spills pose a long-term risk? Organisms living in the ocean are part of a complex web of relationships. In addition, the oil tends to concentrate in the tissues of living organisms and can persist long after the spill has been cleaned up.

Generally, oil spills harm ocean life in two ways: Oil toxicity: Oil consists of many different toxic compounds. These toxic compounds can cause severe health problems like heart damage, stunted growth, immune system effects, and even death.

Oil spills are harmful to marine birds and mammals as well as fish and shellfish. Following an oil spill, there are specialists and veterinarians to deal with oiled wildlife. These experts are trained on how to clean oil from animals, rehabilitate them, and return them to the environment.

Oil pollution can have a devastating effect on the water environment, it spreads over the surface in a thin layer that stops oxygen getting to the plants and animals that live in the water. harms animals and insects. prevents photosynthesis in plants. disrupts the food chain.

At least four species of marine mammals have been killed by the oil spill, including bottlenose dolphins, spinner dolphins, melon-headed whales and sperm whales.

Studies of biomarkers have uncovered irreparable harm to humans exposed to oil and gas from spills. These effects can be grouped into respiratory damage, liver damage, decreased immunity, increased cancer risk, reproductive damage and higher levels of some toxics (hydrocarbons and heavy metals).

Once an oil spill has been deemed “cleaned”, it’s not surprising that there are a number of long-term effects on the environment and nearby ecosystems. Crusty balls filled with soft, gooey oil known as “tarballs” continue to wash up onshore months or years later after a spill.

Given how quickly oil can spread in rough seas, though, this is an extremely difficult process, and only 10 to 15 percent is typically recovered in major maritime spills. Once oil waste is recovered, it is classified by type.

He estimated that the damage to the reefs could last two to five years, but that other oil spills have shown that in some instances it can be longer than that.

« BACK TO FAQ It is estimated that cleanup costs for a medium-large oil spill could be between $2.4 billion and $9.4 billion dollars. Cleanup costs for an oil spill could be between $2.4 billion and $9.4 billion dollars.

BP Exploration and Production Inc. pleaded guilty to 14 criminal counts for its illegal conduct leading to and after the 2010 Deepwater Horizon disaster, and was sentenced to pay $4 billion in criminal fines and penalties, the largest criminal resolution in U.S. history, Attorney General Holder announced today.

Dispersants and booms and skimmers are the most frequently used methods to clean up ocean oil spills. All methods have advantages and disadvantages. The effectiveness depends on the situation – the amount and type of oil, the ocean currents and tides and the weather.

Oil-covered rocks after a spill In emulsification, the oil mixes with water and the resulting oil/water mixture can take on a thick, pudding-like consistency. Emulsified oil is very difficult to clean up using standard means (sorbents, dispersants, skimmers, etc.).
