The Chicago flood occurred on April 13, 1992, when repair work on a bridge spanning the Chicago River damaged the wall of an abandoned and disused utility tunnel beneath the river. The resulting breach flooded basements, facilities and the underground Chicago Pedway throughout the Chicago Loop with an estimated 250 million US gallons (1,000,000 m3) of water. The remediation lasted for weeks, and cost about $2 billion in 1992 dollars, equivalent to $4.17 billion in 2022. The legal battles lasted for several years, and disagreement over who was at fault persists to this day.
Newark Bay is a tidal bay at the confluence of the Passaic and Hackensack Rivers in northeastern New Jersey. It is home to the Port Newark-Elizabeth Marine Terminal, the largest container shipping facility in Port of New York and New Jersey, the second busiest in the United States. An estuary, it is periodically dredged to accommodate seafaring ships.
A berm is a level space, shelf, or raised barrier separating areas in a vertical way, especially partway up a long slope. It can serve as a terrace road, track, path, a fortification line, a border/separation barrier for navigation, good drainage, industry, or other purposes.
In usage in the Southern United States, a bayou is a body of water typically found in a flat, low-lying area. It may refer to an extremely slow-moving stream, river, marshy lake, wetland, or creek. They typically contain brackish water highly conducive to fish life and plankton. Bayous are commonly found in the Gulf Coast region of the southern United States, especially in the Mississippi River Delta, though they also exist elsewhere.

The Mississippi River Delta is the confluence of the Mississippi River with the Gulf of Mexico in Louisiana, southeastern United States. The river delta is a three-million-acre area of land that stretches from Vermilion Bay on the west, to the Chandeleur Islands in the east, on Louisiana's southeastern coast. It is part of the Gulf of Mexico and the Louisiana coastal plain, one of the largest areas of coastal wetlands in the United States. The Mississippi River Delta is the 7th largest river delta on Earth (USGS) and is an important coastal region for the United States, containing more than 2.7 million acres of coastal wetlands and 37% of the estuarine marsh in the conterminous U.S. The coastal area is the nation's largest drainage basin and drains about 41% of the contiguous United States into the Gulf of Mexico at an average rate of 470,000 cubic feet per second.
The wetlands of Louisiana are water-saturated coastal and swamp regions of southern Louisiana, often called 'Bayou'.
William Kane Reilly was Administrator of the Environmental Protection Agency under President George H. W. Bush. He has served as president of World Wildlife Fund, as a founder or advisor to several business ventures, and on many boards of directors. In 2010, he was appointed by President Barack Obama co-chair of the National Commission on the BP Deepwater Horizon Oil Spill and Offshore Drilling to investigate the oil spill in the Gulf of Mexico.
Puget Sound Bridge and Dredging Company was a major shipbuilding and construction company, located in Seattle, Washington, on the southwestern corner of Harbor Island, an artificial island in Elliott Bay. The Bridge and Dredging Company created the island, completing its construction in 1909. It established itself in 1898 and engaged in construction projects around the United States and shipbuilding for the U.S. Navy during and after World War II. During the war it also operated under the name Associated Shipbuilders in a joint venture with the nearby Lake Union Dry Dock Company. In 1959 Lockheed purchased the shipyard and it became the Lockheed Shipbuilding and Construction Company. The Yard was permanently closed in 1987.
The Water Resources Development Act of 1999, Pub. L.Tooltip Public Law 106–53 (text)(PDF), was enacted by Congress of the United States on August 17, 1999. Most of the provisions of WRDA 1999 are administered by the United States Army Corps of Engineers.
The Coastal Wetlands Planning, Protection and Restoration Act (CWPPRA) was passed by Congress in 1990 to fund wetland enhancement. In cooperation with multiple government agencies, CWPPRA is moving forward to restore the lost wetlands of the Gulf Coast, as well as protecting the wetlands from future deterioration. The scope of the mission is not simply for the restoration of Louisiana's Wetlands, but also the research and implementation of preventative measures for wetlands preservation.

The Deepwater Horizon oil spill was an environmental disaster which began on April 20, 2010, off the coast of the United States in the Gulf of Mexico on the BP-operated Macondo Prospect, considered the largest marine oil spill in the history of the petroleum industry and estimated to be 8 to 31 percent larger in volume than the previous largest, the Ixtoc I oil spill, also in the Gulf of Mexico. Caused in the aftermath of a blowout and explosion on the Deepwater Horizon oil platform, the United States federal government estimated the total discharge at 4.9 MMbbl. After several failed efforts to contain the flow, the well was declared sealed on 19 September 2010. Reports in early 2012 indicated that the well site was still leaking. The Deepwater Horizon oil spill is regarded as one of the largest environmental disasters in world history.
The following is a timeline of the Deepwater Horizon oil spill. It was a massive oil spill in the Gulf of Mexico, the largest offshore spill in U.S. history. It was a result of the well blowout that began with the Deepwater Horizon drilling rig explosion on April 20, 2010.
Following is a timeline of the Deepwater Horizon oil spill for June 2010.
Following is a Timeline of the Deepwater Horizon oil spill for May 2010.
The Kalamazoo River oil spill occurred in July 2010 when a pipeline operated by Enbridge burst and flowed into Talmadge Creek, a tributary of the Kalamazoo River near Marshall, Michigan. A 6-foot (1.8 m) break in the pipeline resulted in one of the largest inland oil spills in U.S. history. The pipeline carries diluted bitumen (dilbit), a heavy crude oil from Canada's Athabasca oil sands to the United States. Cleanup took five years. Following the spill, the volatile hydrocarbon diluents evaporated, leaving the heavier bitumen to sink in the water column. Thirty-five miles (56 km) of the Kalamazoo River were closed for clean-up until June 2012, when portions of the river were re-opened. On March 14, 2013, the Environmental Protection Agency (EPA) ordered Enbridge to return to dredge portions of the river to remove submerged oil and oil-contaminated sediment.
Water pollution in the United States is a growing problem that became critical in the 19th century with the development of mechanized agriculture, mining, and industry, although laws and regulations introduced in the late 20th century have improved water quality in many water bodies. Extensive industrialization and rapid urban growth exacerbated water pollution as a lack of regulation allowed for discharges of sewage, toxic chemicals, nutrients and other pollutants into surface water.
Breton Island is an island in the Gulf of Mexico near the mouth of the Mississippi River and part of Plaquemines Parish, Louisiana. It is part of the Breton National Wildlife Refuge, which was established in 1904.
The Deepwater Horizon oil spill occurred between 10 April and 19 September 2010 in the Gulf of Mexico. A variety of techniques were used to address fundamental strategies for addressing the spilled oil, which were: to contain oil on the surface, dispersal, and removal. While most of the oil drilled off Louisiana is a lighter crude, the leaking oil was of a heavier blend which contained asphalt-like substances. According to Ed Overton, who heads a federal chemical hazard assessment team for oil spills, this type of oil emulsifies well. Once it becomes emulsified, it no longer evaporates as quickly as regular oil, does not rinse off as easily, cannot be broken down by microbes as easily, and does not burn as well. "That type of mixture essentially removes all the best oil clean-up weapons", Overton said.
