  • EPA targets electric utilities - the agency steps up efforts to manage coal ash damage

    Approximately 5.4 million cubic yards, or 1.1 billion gallons, of coal ash from the Tennessee Valley Authority (TVA) plant near Knoxville, Tenn., in December 2008 flooded some 300 acres of land, damaging property, polluting waterways, and killing fish. TVA will likely spend more than $500 million and perhaps as much as $1 billion dollars on the cleanup, says the U.S. Environmental Protection ...

  • Time to stop losing ocean data to vandalism

    More must be done to prevent damage of ocean data buoys that costs money, vital data — and lives, say Sidney Thurston and M. Ravichandran. The global community relies on a rapidly expanding ocean observing network to understand the climate and ecosystems, to help warn against ocean-borne hazards such as tsunamis and storm surges caused by cyclones, and to support sea rescue ...

  • Environmental Industrial Water & Algae Control in lagoons and ponds.

    Proven site trails and report shows a excellent reduction/removal of Microcystis and filamentous algae where we proved excellent results with ASMP-1000.A systems These ponds are characterised by large open lagoons with a fairly high residence time of water and UV exposure in the summer months. During the holding period in the open reservoirs, filamentous algae start growing ...

  • The Role of Mangroves in Fisheries Enhancement

    In 2011 humans caught and consumed 78.9 million tonnes of fish, crustaceans, molluscs and other species groups from the world’s oceans, accounting for 16.6% of the world’s animal protein intake (FAO 2012). This is projected to increase further, to over 93 million tonnes by 2030 (World Bank 2013). Global demand for fish products has increased dramatically over recent decades. Fishing ...

  • Legal lookout: EPA responds to coal ash release

    Once again, it took a major catastrophe to wake up industry and regulators to a problem that should have been addressed long ago. Dec. 22, 2008, was a nightmare for federal and state regulators, electrical utilities, and most particularly the residents of Kingston, Tenn. On this day, approximately 5.4 million cubic yards (or 1.1 billion gallons) of coal ash from the Tennessee Valley Authority ...

  • Toxicity of forest fire retardant chemicals to stream‐type Chinook salmon undergoing parr–smolt transformation

    Long‐term fire retardants are used to prevent the spread of wildland fires. These products are normally applied by aircraft and are intended specifically for terrestrial application, but fire retardants have entered aquatic habitats by misapplication and/or accidental spills and have resulted in fish mortalities. The authors examined the toxicity of two fire retardant products, PHOS‐CHEK 259F ...

  • 3 Ways to get rid of birds on golf courses

    Birds – Canadian Geese especially – can be a nuisance on the golf course. Canadian Geese get in the way of golfing and are known to be aggressive and territorial, especially when they are nesting. They cause physical damages on the golf course and their droppings can spread bacteria like E. coli and listeria to other animals or golfers. See what you can do to help get rid of birds on ...

  • Balancing Environmental Concerns with Beach Attractiveness

    Maintaining beaches that are free of human debris often creates a challenge, because synthetic debris often mixes with natural organic deposits from the ocean, like seaweed. For many beach owners and locations, removing seaweed and other debris at the tide line using mechanical beach cleaners is no problem, and actually, preferred. This creates a pristine beach for visitors to enjoy. In addition ...

  • Valuing Plastic – The Case for Business Action

    Concern is growing over the threat that widespread plastic waste poses to marine life, with conservative estimates of the overall financial damage of plastics to marine ecosystems standing at US$13 billion each year, according to two reports released last week at the first United Nations Environment Assembly. The eleventh edition of the United Nations Environment Programme (UNEP) Year Book looks ...

  • How do You Know When You Need Commercial Plumbers

    In your day-to-day routine, either at home or at your business, the plumbing doesn’t get much attention. That is, until it starts showing warning signs of problems via sinks, tubs, and shower stalls not draining, toilets not flushing, or sewage backing up into your basement. It’s true you can buy drain openers and cleaners in the hardware store or even in the grocery store, but these ...

  • Least-Cost Approaches to Reducing Acid Emissions

    ' The costs of meeting sulfur emission targets can be high. It is essential, therefore, that countries adopt policies which (a) minimize the net economic and social costs of reducing emissions to the agreed target levels, and (b) maximize the overlap between measures designed to reduce acidifying emissions and those addressing other forms of air pollution. This note discusses alternative ...

  • The number one thing we can do to protect Earth’s oceans

    Marine governance favors consumption and commerce over conservation. Here's what we can do about it. When New England fishers complained of working harder and harder to catch fewer and fewer fish, Spencer Baird assembled a scientific team to investigate. Though a fishery failure would once have seemed inconceivable, Baird wrote in his report, “an alarming decrease of the ...

  • Late lessons from early warnings: science, precaution, innovation

    With much scientific uncertainty about the real impact of new products and technologies, policy-makers face difficult decisions, particularly when they have to deal with powerful commercial interests and economic trade-offs. The back stories of some widely used innovations of the past, such as leaded petrol, mercury products, DBCP pesticide, vinyl chloride, DDT, tobacco, and fossil fuel energies ...

  • Mercury Analysis

    Characteristics of Mercury What is Mercury? Mercury is a naturally occurring silver-colored metallic element noted for its occurrence as a liquid at room temperature and toxic to living organisms. This silvery, opaque liquid metal is very dense, yet has a high surface tension that causes it to form tiny perfect spheres in the pores of the rocks it is found in. It is ...

  • Managing oceans with sound science

    Management of marine resources for sustainable development needs local capacity for science, particularly in the Pacific region. Those who care about environmental damage and its effects on the health and welfare of communities tend to focus on land-based threats. That is where harm can be most easily observed, and where its causes — from agricultural pesticides to industrial air ...

  • ENVIRONMENTAL MANAGEMENT: Algae recruited for waterways clean-up

    Most people have heard about the canary in the cage; the hapless sentinel that warns miners of lethal build-ups of poisonous gas by falling off its perch, dead. Researchers have applied a similar principle to their development of a procedure for identifying and removing toxicants from estuarine and coastal waters, using highly sensitive algae as toxicity test subjects. The use of such ‘lower ...
