This time we leave the Marcellus Shale region and set our sights a bit southwest, to Clinton—er, former Clinton—territory: Little Rock, AR. Seems folks there aren’t convinced that fracking’s the way to go to drill for natural gas—at least not in their backyard. Also seems like fracking’s become the NIMBY hot-button issue of the day, reminiscent of the tenor that swept the nation when the Three Mile Island core meltdown was hot and heavy in the news. NIMBY indeed.
The backyard in question here, however, happens to be government-owned land—namely the Ozark National Forest, and also Greers Ferry Lake. The plaintiffs, which are a collective of environmental groups and concerned citizens, are calling for three US government agencies (US Bureau of Land Management (BLM), US Forest Service and the US Army Corps of Engineers) to stop drilling operations from going forward until proper studies are done that show that fracking is not harmful to the environment.
Hydraulic fracturing (aka “fracking”) has been getting a fair amount of attention in the press lately—thanks in large part to the work that Public Citizenand other consumer advocacy groups have been doing. The issue with fracking is that the drilling process calls for massive amounts of water combined with chemicals—chemicals that have not fully been disclosed yet to the public by the oil companies—to be forced into the ground in order to facilitate (ie, by helping to “fracture” the underground) the release of the natural gas below.
Environmental groups, farmers and homeowners alike who live in areas where fracking is going on are concerned for the safety of their drinking water, their land—their very health. The EPA is conducting a study to assess the overall impact on water quality and human health—but those results are not available yet, and of course, there are plenty of oil-industry-backed or -initiated studies proclaiming the merits and safety of fracking. So bottom line, until the EPA study is available, anecdotal information—such as that of flammable tap water—doesn’t have too many folks grabbing a glass of their local water well’s finest with much confidence.
It’s that lack of information and lack of confidence that forms the backdrop to the current charges of the lawsuit. The plaintiffs’ allegations state that the number of wells in which drilling is already going on in the region surpasses the number that were estimated in 2005 by the BLM—and its the agencies listed as defendants in the lawsuit that are responsible for leasing the gas and issuing drilling licenses on land owned by the government.

Okay, we all know that those fluorescent bulbs are more efficient than incandescent bulbs. They last longer, and reduce greenhouse gasses.
And everyone is on the bandwagon. Canada starts phasing out incandescent bulbs starting next year. In the US, it’s 2014. Australia led the way in 2007, and the European Union came soon after.
Here’s the thing. Incandescent light bulbs, as inefficient as they are, don’t contain mercury.
But fluorescents do.
Okay fine, the mercury is in the bulb and as long as they don’t break…
Indeed.
Yes, mercury is a naturally occurring element, just as the inert gas used in the incandescent bulb is also naturally occurring. The difference with mercury is that it’s a neurotoxin that can damage the brain, spinal cord, kidneys and liver through chronic exposure.
Health Canada says, “Mercury can impair the ability to feel, see, move and taste and can cause numbness and tunnel vision. Long-term exposure can lead to progressively worse symptoms and ultimately personality changes, stupor and in extreme cases, coma or death,” according to Health Canada.
The regulator goes on to say that recent research suggests even at low levels, mercury can have adverse health impacts on the cardiovascular and immune system.
Here’s the question. What happens to all these bulbs when they are spent? And what happens if they break en route to a disposal facility?
The U.S. Environmental Protection Agency estimates that three per cent of the total mercury in Read the rest of this entry »
