In a detailed assessment of the Deepwater Horizon oil spill, researchers led by a team from the Woods Hole Oceanographic Institution (WHOI) have determined that the blown-out Macondo well spewed oil at a rate of about 57,000 barrels a day, totaling nearly 5 million barrels of oil released from the well between April 20 and July 15, 2010, when the leak was capped. In addition, the well released some 100 million standard cubic feet per day of natural gas
About 20 percent of untreated water samples from public, private, and monitoring wells across the nation contain concentrations of at least one trace element, such as arsenic, manganese and uranium, at levels of potential health concern, according to a new study by the U.S. Geological Survey.
Baylor University environmental researchers have proposed in a new study a different approach to predict the environmental safety of chemicals by using data from other similar chemicals.
The U.S. Environmental Protection Agency (EPA) recently announced a new tool to allow 28 industrial sectors to submit their 2010 greenhouse gas (GHG) pollution data electronically.
Carbon dioxide still plays a major role in climate change, but other greenhouse gases contribute to the problem.
Fallen autumn leaves transfer as much, if not more, hazardous mercury from the atmosphere to the environment as does precipitation each year, according to recent U.S. Geological Survey research.
Researchers found that bacterial microbes inside the slick degraded the oil at a rate five times faster than microbes outside the slick—accounting in large part for the disappearance of the slick some three weeks after Deepwater Horizon's Macondo well was shut off.
Aerosol particles, including soot and sulfur dioxide from burning fossil fuels, essentially mask the effects of greenhouse gases and are at the heart of the biggest uncertainty in climate change prediction.
The U.S. Environmental Protection Agency (EPA) and the U.S. Department of Justice announced that Dow Chemical Company has agreed to pay a $2.5 million civil penalty to settle alleged violations of the Clean Air Act, Clean Water Act and the Resource Conservation and Recovery Act (RCRA) at its chemical manufacturing and research complex in Midland, Mich.
U.S. District Court Judge Adalberto Jordan sentenced Brendan Clery, 34, to 18 months in prison and ordered him to pay a $10,000 criminal fine and forfeit illegal proceeds in the amount of $935,240.
The Robert J. Dole Veterans Administration Medical Center in Wichita, Kan., has agreed to pay a $17,979 civil penalty to the United States to settle a series of hazardous waste violations on its campus.
Greenhouse gas (GHG) emissions have been reduced by an accumulated 5.7 million metric tonnes (mt) in Mexico City since it began implementing its Green Plan in 2008, the Mexico City government recently announced.
Surface water quality is important for the proper function of aquatic ecosystems, as well as human needs and recreation. Pasturelands have been found to be major sources of sediment, phosphorus and pathogens in Midwest surface water resources.
After collecting weathered crude oil from the Gulf of Mexico following the Deepwater Horizon oil spill, researchers at Texas Tech University have reported that only 8 to 9 percent coverage on the shells of fertilized mallard duck eggs resulted in a 50 percent mortality rate.
Quantum dots made from cadmium and selenium degrade in soil, unleashing toxic cadmium and selenium ions into their surroundings, a University at Buffalo study has found.
Taking another major step in sleuthing the 2010 Deepwater Horizon oil spill, a research team led by the Woods Hole Oceanographic Institution (WHOI) has determined what chemicals were contained in a deep, hydrocarbon-containing plume at least 22 miles long that WHOI scientists mapped and sampled last summer in the Gulf of Mexico, a residue of the Deepwater Horizon oil spill.
Tenaris Global Services Corp., a manufacturer and supplier of steel pipe products for the oil and energy industry, has agreed to pay $717,324 of civil penalties to the United States to settle violations of environmental regulations at seven facilities related to the public reporting of toxic chemicals at its facilities in Louisiana, Texas and Arkansas.
As the process of recovering from the May 22 tornado in Joplin, Mo., nears the end of its eighth week, EPA Region 7 is urging residents and cleanup crews to keep residential storm debris segregated into six categories to speed curbside collection efforts.
Companies in Massachusetts and Vermont company that store significant amounts of oil are facing EPA penalties of up to $177,500 for failing to take adequate precautions to prevent and contain spillage of that oil.
Chemically bonded phosphate ceramics create a passivation layer that stops corrosion and is protected by a tough ceramic outer layer. These compounds protect metal from corrosion better than other options, such as polymer paints, and are less expensive than using stainless steel.
