Contaminated Drinking Water Causes BPD?

What?! Water now? A new study had shown there to be a link between exposure to to tetrachloroethylene (also known as perchloroethylene or PCE), a common byproduct of the textile industry, in drinking water early in life and bipolar disorder, post traumatic stress disorder (PTSD), and schizophrenia later in life. PCE is a colorless organic liquid that is used in dry cleaning and is also used to clean metals. EPA has set an enforceable regulation for tetrachloroethylene (a maximum contaminant level [MCL]) of 0.005 mg/L or 5 ppb (parts per billion). Is nothing safe? Or is this another one of those fear studies? In the last we can safely assume that any toxic chemical isn't going to do wonders on your health.
