Boy, it’s all arsenic all the time on this blog!

Chemical & Engineering News: Latest News – In Katrina’s Wake, An Arsenic Threat

An incredible 72 million m3 of debris was created when Hurricane Katrina wreaked havoc in Louisiana and Mississippi in 2005. A survey of this debris now reveals that an estimated 1,740 metric tons of arsenic could leach into groundwater from unlined landfills where the materials are being disposed (Environ. Sci. Technol., DOI: 10.1021/es0622812).

Here’s EPA’s page on arsenic treated wood, and here’s the cheerleader page for same (mmm, industry advocacy websites, delicious!). Note that the EPA is currently working with the manufacturers to “voluntarily” phase out the use of Chromated Copper Arsenate in residential settings. Note that there are several alternatives available, all of them less toxic and equally effective. While this “voluntary” action limits direct exposure for certain types of people, old wood ending up in unlined landfills will overwhelmingly affect people who live near said landfills, namely the poor, and African American

Even lined landfills leak eventually, and while other organic matter may degrade before the leaking, arsenic and heavy metals are not going anywhere. Unlined landfills, which is a fancy way of saying hole in the ground where you throw trash in, are completely unacceptable in this day and age in a so called developed country like the US of A. On the other hand, it is fashionable to refer to Louisiana as a third world country, so I guess anything goes for those kinds of people, eh.

  • New Source Review stands for now

    Cinergy, now Duke Energy, was trying to claim that as long as its plants’ hourly emission rate did not increase, they could make unlimited “modifications” to the plants. So, in theory, if capacity got doubled so a plant was operating 24 hours a day from 12, the hourly rate would remain the same, but pollution would double. Well,  isn’t that a “new source” then? Apparently, Cinergy did not think so, and after at least 6 years of wrangling, this thing is going to be decided by the Supreme Court this fall. So, once again, the crack team of Roberts, et al. will decide whether we breathe or not, policy by judicial fiat?

    US court hands EPA a win in utility emission case | Reuters.com

    A federal court has ruled that a big U.S. utility must install costly pollution-reduction equipment at its aging coal-powered electric plants if it expands them, handing a victory to the U.S. government in a case that could shape an upcoming Supreme Court ruling.

    The three-member 7th Circuit Court of Appeals in Chicago on Thursday ruled that Cinergy must install emission curbs at its coal-powered plants in the Midwest if it expands them to prolong their operating lives.

    The Environmental Protection Agency had sued the utility to force it to apply for an expansion permit, which would trigger emission-reduction measures.

    In a bevy of cases, U.S. utilities are testing how far they can go to expand aging plants without triggering a section of the Clean Air Act known as “New Source Review.”

    Arsenic in the News

    Professor wins $1M for arsenic filter – Yahoo! News

    The National Academy of Engineering announced Thursday that the 2007 Grainger Challenge Prize for Sustainability would go to Abul Hussam, a chemistry professor at George Mason University in Fairfax. Hussam’s invention is already in use today, preventing serious health problems in residents of the professor’s native Bangladesh.

    This British Geological Survey website provides a good primer to the problem. Some key points:

    1. Arsenic is very toxic
    2. Arsenic is naturally occurring in the shallow groundwater aquifers of Bengal and Bangladesh at a toxic level
    3. The surface water is contaminated with bacteria and was responsible for high infant mortality, so aid agencies in the ’70s encouraged the use of tube wells and other groundwater pumps. While this contributed to a decline in infant mortality from gastrointestinal infections, it also dosed unsuspecting people with disease causing levels of arsenic
    4. The technology for removal of arsenic is very well known. But most solutions require electricity/periodic maintenance/technical skills and are thus not universal or sustainable.
    5. Simplicity is the key. You can’t tell the people to not drink the water, it is the only clean water available. You can’t install water treatment plants, there is no running water, you can’t rely on solutions that are centralized.

    So with all that in mind, here’s what Prof. Hussam did:

    The Gold Award-winning SONO filter is a point-of-use method for removing arsenic from drinking water.  A top bucket is filled with locally available coarse river sand and a composite iron matrix (CIM).  The sand filters coarse particles and imparts mechanical stability, while the CIM removes inorganic arsenic.  The water then flows into a second bucket where it again filters through coarse river sand, then wood charcoal to remove organics, and finally through fine river sand and wet brick chips to remove fine particles and stabilize water flow.  The SONO filter is now manufactured and used in Bangladesh. That’s great, and easy!

    That’s pretty much freshman chemistry right there, further proof that most innovation does not need new science, only people willing to spend some time on problems that don’t necessarily get looked at.

  • E.P.A. Says 17 States Can’t Set Emission Rules for Cars

    Shameful. I did not blog much, or anything about the recently passed energy bill because I thought it was a watered down compromise that subsidized coal, oil and ethanol industries at the expense of renewable energy, public transportation and public health. But these are the consequences of passing such a bill, it allows the EPA to claim that something major has already been done, so noting needs to be done any more .

    The E.P.A. administrator, Stephen L. Johnson, said the proposed California rules were pre-empted by federal authority and made moot by the energy bill signed into law by President Bush on Wednesday. Mr. Johnson said California had failed to make a compelling case that it needed authority to write its own standards for greenhouse gas emissions from cars and trucks to help curb global warming.

    E.P.A. Says 17 States Can’t Set Emission Rules for Cars – New York Times

    This is truly absurd. The energy bill does not address CO2 emissions. California has used its right to set stronger standards many times in the past, and nothing in this bill preempts this right.

    I guess this is Supreme Court bound, where that one man decision making machine Justice Kennedy will no doubt set the standards for this country.

  • Signs of the Rapture – Killer Algae

    This time, it’s the killer algal bloom, to add to the dying bees and the dying fish.

    Algae killing birds, sealife in Calif. – Yahoo News

    A bloom of ocean algae that produces a toxic acid has sickened and killed hundreds of birds, sea lions and dolphins in California, environmentalists said.

    Birds and animals have been washing up on shores from San Diego to San Francisco Bay.

    In the past week, 40 birds have been taken to the International Bird Rescue Center in San Pedro with symptoms of domoic acid poisoning, which attacks the brain and can cause seizures.

    In previous seasons, the center might see seven birds a week, director Jay Holcomb said.

    “I have been doing this work for 35 years and I have never seen anything like this as far as the number of species affected, other than an oil spill,” Holcomb said Thursday.

    Domoic acid is produced by microscopic algae. Birds and sea mammals ingest the acid by eating fish and shellfish who dine on the algae.

    The algae population increases or “blooms” every year as the ocean waters warm but this year’s bloom seems early, extensive and “very, very thick,” said David Caron, who teaches in the biological sciences department at University of Southern California.

    “In five years of study I have not seen a bloom this large at this particular time of year,” Caron said. “It’s having an extraordinary impact on pelicans and many other species.”

    “There are conceivably thousands of animals being affected,” Caron said.

    domoic acidDomoic acid is a naturally occuring toxin from red algae. Increased nutrient loadings into the ocean, and warming ocean temperatures are both linked with an increasing incidence of this toxic “red tide“. It is a naturally occurring phenomenon every year, so it is hard to tease out human inputs and just plain ol’ natural variation. One more thing to keep an eye on, I guess.

    Statutory Disclaimer: I don’t actually believe in the rapture – it’s just a cheap rhetorical trick.

    Power to Build Border Fence Is Above U.S. Law

    Banana Republic Alert…

    Securing the nation’s borders is so important, Congress says, that Michael Chertoff, the homeland security secretary, must have the power to ignore any laws that stand in the way of building a border fence. Any laws at all.

    Last week, Mr. Chertoff issued waivers suspending more than 30 laws he said could interfere with “the expeditious construction of barriers” in Arizona, California, New Mexico and Texas. The list included laws protecting the environment, endangered species, migratory birds, the bald eagle, antiquities, farms, deserts, forests, Native American graves and religious freedom.

  • Carrboro Screening of "After the Peak"

    I happened to watch an interesting short film called After the Peak about peak oil, the concept (not that revolutionary unless you ask Messrs  Exxon-Mobil, Shell and Dick Cheney!) that oil production will start declining after a certain peak production event. The docudrama made by local film maker James McQuaid was part of a public meeting on the local (Orange County, NC) responses to the coming energy crisis. Interesting conceptually, it was shown as a 30 minute local newscast, with the usual cast of characters, the too handsome eye candy anchor and his female sidekick, the young and breathless “street reporter”, the gray haired expert, and the uber-energetic sports guy! The newscast is set a year into the future when the price of gas is $10/gallon. The documentary of interviews with various community members about the effects of the price of gas on their business/life. In the 30 minutes, he touched upon food, school buses, sports, NASCAR, the poor, commutes, etc. It was an interesting effort, if a little over the top! The fake interviews with the racing track owner who’s closing his track down, the UNC athletic director who has to cancel all his long distance events, the manager of the local food store who threatens food scarcity.

    But is $10 a gallon really a big deal?

    gas-prices.png

    This simple chart shows income adjusted dollar per gallon gas prices (gas prices from 2006, income from 2004, but it should not change too much.)

    Let’s avoid the low income outliers and just compare the U.S and Germany. In April 2006, the U.S was paying $2.95 a gallon and Germany, $8.06 per gallon (ref). If you further adjust that with the per capita income of the two countries, $41,300 for the U.S versus $30,500 for Germany (ref), you will find that the price of gas in Germany is well above $10 a gallon already, they seem to be doing just fine! Maybe they just drive less. The US uses 381 million gallons of gas per day (that’s about 1.2 gallons per day per person). I agree that this comparison is a little flawed because the bulk of the German price is due to taxes, which go back to the government and are presumably used for various good deeds. Also, if the price of gas went up due to shortages, the price differential between Germany and the US would presumably stay constant (unless the Germans lowered taxes). My point is that many countries cope with high gas prices quite well, they just don’t make the same choices the Americans make, 1 acre lots, large SUVs, super long commutes, etc. There are a lot of efficiencies to be had here. The graph below shows the income adjusted gasoline price for a few countries (easy data was available!)

    My take: we need to swiftly move away from gasoline by a) Disincentivizing the use of gasoline in transportation b) Incentivizing the use of electricity for transportation. Electricity can be produced more efficiently, and pollution at the source can be controlled more effectively. A combination of a drastic increase in solar and wind power, coupled with aggressive development in battery technology should more than solve our problem without much recourse to biofuels (that great boondongle).
