  • Lowest level for lake mead

    In August 2010, Lake Mead reached its lowest level since 1956. Two images from the Thematic Mapper on the Landsat 5 satellite show some of the stark changes on the eastern end of the lake since 1985. The largest reservoir in the United States was straining from persistent drought and increasing human demand. Badger Cove, Driftwood Cove, and Grand Wash Bay have receded to become valleys ...

  • The effect of global warming on eutrophication in lakes

    Shallow lakes are an important type of ecosystem that may be vulnerable to current warming trends. A recent study examines just how vulnerable they are. It indicates that climate change combined with nutrient pollution could exacerbate eutrophication and suggests nitrogen levels should be monitored. Shallow lakes are important in their support of biodiversity. However, their large ...

  • Measure Great Lakes cleanup progress

    An Obama administration program that has spent more than $1.3 billion on healing the troubled Great Lakes needs a better scorecard for measuring its performance, a government watchdog report released Friday says.

  • NASA Researchers Discover Ancient Microbes In Antarctic Lake

     In one of the most remote lakes of Antarctica, nearly 65 feet beneath the icy surface, scientists from NASA, the Desert Research Institute (DRI) in Reno, Nev., the University of Illinois at Chicago, and nine other institutions, have uncovered a community of bacteria. This discovery of life existing in one of Earth's ...

  • Hurricane Ike’s effects linger in the Great Lakes

    Although Hurricane Ike is long gone, its impact lingers more than a thousand miles from where it made landfall.  Runoff from tributaries dumped massive amounts of sediment into Lake Michigan, contaminating the water, compromising near-shore navigation and raising E coli bacteria to levels unsafe for swimming. According to Richard Whitman, a U.S. Geological Survey (USGS) expert on beach health, ...

  • Toxics Persist in Washington Rivers, Lakes and Fish

    OLYMPIA, Washington - Toxic chemicals banned decades ago continue to linger in the environment and concentrate in the food chain, threatening people and the environment, according to three recent studies by the Washington state Department of Ecology. The new data on toxic contaminants in freshwater fish and sediments add evidence to the state's push to reduce and eliminate the use of toxic ...

  • EPA Proposes Revised Plan to Remove Mercury Contaminated Sediment from Bottom of Pompton Lake in Pompton Lakes, New Jersey

    The U.S. Environmental Protection Agency today proposed a new plan to remove mercury contamination from areas of Pompton Lake in Pompton Lakes, New Jersey, including the areas where the Acid Brook flows into the lake, called the Acid Brook Delta. Areas of the sediment on the bottom of the lake have become contaminated with mercury and lead that flowed down the Acid Brook into the lake. The public ...

  • Great Lakes Legacy Act Ottawa River cleanup has begun

    U.S. Environmental Protection Agency, the Ottawa River Group and the state of Ohio have begun dredging 240,000 cubic yards of contaminated sediment from a 5.5-mile section of the Ottawa River in Toledo, Ohio. The first phase of the project – removing 10,000 cubic yards of sediment from Sibley Creek – was completed in April. The US$49 million cost of the total project will be split ...

  • Great Lakes initiative cleanup helps restore grand calumet river

    The recent completion of a $52 million project to rid Roxana Marsh of contaminated sediment will speed the recovery of Indiana’s Grand Calumet River, marking a step forward for one of the Great Lakes’ most complex Area of Concern cleanups. Representatives from U.S. Environmental Protection Agency, U.S. Fish and Wildlife Service and the State of Indiana were joined by Congressman Pete ...

  • Water Sampling Update

    Summer field work has come to a close at the Newberry EGS Demonstration site, and with it we’ve completed the last round of water sampling and analysis. The EGS project was carefully designed to protect the local groundwater system, and our groundwater monitoring program helps us make sure we protect this valuable natural resource. Our water monitoring program was designed to document and ...

  • US river flows altered by water management

    The amount of water flowing in streams and rivers has been significantly altered in nearly 90% of waters that were assessed in a new nationwide USGS study. Flow alterations are a primary contributor to degraded river ecosystems and loss of native species. Flows are altered by a variety of land- and water-management activities, including reservoirs, diversions, subsurface tile drains, groundwater ...


  • Mississippi River an `Orphan` in Terms of Water Quality

    WASHINGTON, DC, October 18, 2007 (ENS) - The U.S. Environmental Protection Agency has failed to coordinate and oversee state water quality activities along the Mississippi River, leaving the nation's largest waterway an 'orphan,' the National Research Council says in a new report. Greater effort is needed to ensure that the river is monitored and evaluated as a single system, said the ...

  • New Reservoir Will Funnel Colorado River Water to Nevada

    LAS VEGAS, Nevada (ENS) - A bill that directs the Bureau of Reclamation to construct a new reservoir to capture billions of gallons of Colorado River water requested by Arizona and California users but not used, was signed into law today by President George W. Bush. Included in the massive HR 6111 Tax Relief and Health Care Act, the measure will enable the capture and use of ...

  • EPA Releases Scientific Report Showing U.S. Coastal Waters a Mix of Good and Fair Health

    Biological Quality is rated good in 56% of coastal and Great Lakes nearshore waters. Healthy communities of bottom-dwelling macroinvertebrates (such as worms and clams), which are indicators of biological quality, are supported in these waters. Water Quality is rated fair in 48% of coastal and Great Lakes waters and good in 36% when measuring phosphorus, nitrogen, water clarity, chlorophyll a, ...

  • EPA to approve California’s newest list of impaired waterways

    More than 40,000 miles of California’s rivers and streams are currently threatened by pollution, according to a list of impaired waterways submitted by the state to the U.S. Environmental Protection Agency. Monitoring of rivers, lakes and coastal waters in California continue to show harmful pollutant levels, based on updates to the list from three of the state’s nine regional Water ...

  • Melting glaciers free trapped pollutants

    Melting glaciers in the Swiss Alps are releasing pollutants that have been frozen in the ice for decades. A recent study suggests that by accelerating global ice loss, global warming is likely to increase environmental contamination with persistent organic compounds that are no longer widely used, such as PCBs and DDT. Persistent organic pollutants are chemicals that can travel long distances in ...

  • Louisiana Included in EPA Assessment of Nation’s Coasts

    The U.S. Environmental Protection Agency (EPA) recently awarded $485,000 to the Louisiana Department of Wildlife and Fisheries (LDWF) for testing water quality along the state’s Gulf Coast. The sampling results will contribute to EPA’s National Coastal Conditions Assessment (NCCA). The NCCA is a survey of our nation’s coastal waters which EPA and state partners conduct to ...

  • Desert dust cuts Colorado river flow

    Snow melt in the Colorado River basin (USA) is occurring earlier, reducing runoff and the amount of crucial water available downstream. A new study shows this is due to increased dust caused by human activities in the region during the past 150 years. The study, led by a NASA scientist and funded by the agency and the National Science Foundation (NSF), showed peak spring runoff now comes three ...
