According to researchers at Columbia University, even small amounts of arsenic in your drinking water can lower children’s IQ. If you’re wondering if your local water supply has arsenic in it, then wonder no more: Just about every water system – private or public – does. The study suggests that 5 or more parts per billion can impact children’s cognitive abilities. The EPA standard for acceptable arsenic levels is 10 parts per billion or less.

Via Press Herald:

Scientists from Columbia University and the University of New Hampshire recently completed a five-year study of 272 schoolchildren in Maine who had been exposed to arsenic in well water. They found that even at low levels, 5 or more parts per billion, the exposure could correlate to lower intelligence, as much as five to six points on IQ tests.

“Everyone was a little taken aback by that,” said professor Amy Schwartz of the University of New Hampshire, who coordinated the testing of Maine children. “This is a great piece of public health research. People shouldn’t panic, but be informed.”

    five to six points on IQ tests
    is statistical noise
    not sayin arsenic is good for you
    butt this study proves that grant money
    requires a published finding

    • Right… on that note, there are real reasons fluoride is used to treat reclaimed waste water that’s hidden in plain sight yet not disclosed in any published findings. No, it’s not placed there by the 4th Reich of Der Homeland functioning as Liquid Autism for the masses. Try telling anyone it’s because the water is so full of residual medications, industrial waste and petroleum byproducts that you need a binding agent to detoxify it.

    The EPA does a cost benefit analysis and sets what they determine to be an enforceable level. How is a new study saying arsenic is bad going to change that? It’s already higher than the scientifically recommended level, which was already zero.

      Whenever I drink a nice, cool glass of water I like to think to myself – mmm, that’s what the industrial revolution tastes like.

    If anyone recalls, Bill Clinton raised standards for arsenic in water right before he left office to sweeten his legacy. W obligingly re-lowered it.

    My comment was hyperbole.

    However, arsenic pollution does have a number of anthropogenic sources – mining, arsenic-based insecticides, coal burning, and chemical treatment of lumber are all sources. An estimated 1.6 million tons of arsenic have been used for industrial & agricultural purposes alone in the US (as referenced by Consumer Reports article posted in the comments here).
