  • Toxic algae blooming in warm water from California to Alaska

    A vast bloom of toxic algae off the West Coast is denser, more widespread and deeper than scientists feared even weeks ago, according to surveyors aboard a National Oceanic and Atmospheric Administration research vessel. This coastal ribbon of microscopic algae, up to 40 miles wide and 650 feet deep in places, is flourishing amid unusually warm Pacific Ocean temperatures. It now stretches from at ...

  • Testing confirms US coastal waters less toxic than 20 years ago

    US environmental laws enacted in the 1970s are reducing overall contaminant levels in coastal waters of the United States, finds a 20 year study released today by scientists with the National Oceanic and Atmospheric Administration, NOAA. But the study shows continuing elevated levels of toxic metals and oils near urban and industrial areas of the coast. Oil related compounds from motor vehicles ...

  • EPA Issues Health Advisories to Protect Americans from Algal Toxins in Drinking Water

    The U.S. Environmental Protection Agency (EPA) today issued health advisory values that states and utilities can use to protect Americans from elevated levels of algal toxins in drinking water. Algal blooms in rivers, lakes, and bays sometimes produce harmful toxins. Because utilities often use these water bodies as sources of drinking water, EPA has determined algal toxin levels in tap water ...

  • Investigation begins to track suspected pollution from the Lahaina wastewater facility (HI)

    Federal and state agencies have begun important research to evaluate the suspected discharge of pollutants to the coastal waters along the Kaanapali coast of Maui. Funded by the U. S. EPA, U.S. Army Corps of Engineers, and the Hawaii Department of Health, the University of Hawaii will measure how long it takes for wastewater from the Lahaina sewage treatment facility to flow to the near-shore ...

  • Toxicity tests improve the assessment of harbour sediment quality

    Harbour sediments should be tested for their toxic effects on living organisms in addition to being subject to the chemical, physical and biological tests usually conducted to assess water quality, according to recent research from Portugal. This would provide a better environmental assessment of dredged material to help guide port authorities’ decisions on its disposal. Under the Water ...

  • EPA Proposes Changes to Cleanup Plan at Cattaraugus County, NY Toxic Site Public Meeting to take place August 5 in Olean

  • Washington State Continues Permits for Aquatic Pesticides

    OLYMPIA, Washington (ENS) - The Washington state Department of Ecology will continue using permits to control the use of aquatic pesticides in and around state waters. Use of the permits came into question when the U.S. Environmental Protection Agency, EPA, ruled in November 2006 that a pesticide applied according to the federal label is not a pollutant under the federal Clean ...

  • Are Toxic Chemicals in Your Gardening Tools?

    Testing shows that many common gardening tools—including hoses, gloves, kneeling pads, shovels, and trowels—are contaminated with harmful chemicals, claims the nonprofit environmental group Ecology Center. CNN reports that the organization analyzed 200 popular gardening products and found that two-thirds of them contained significant levels of phthalates, bisphenol A (BPA), and lead. ...
