"It's become very fashionable I think to carry around bottled water from France or Iceland to think that we could somehow opt out of the water cycle, but in fact the scientific studies are showing us that the majority of our exposure to contaminants in drinking water don't come actually from drinking it, it comes from inhalation. So we're actually breathing water pollutants, and that happens every time you turn on your shower, every time you turn on your dishwasher, every time you do a load of laundry.
"It turns out that jumping in the shower for 10 minutes is the exposure equivalent of drinking a 1/2 gallon of tap water. Meaning that you can drink all the bottled water you want if you feel concerned that perhaps there are contaminants in your drinking water that you don't want to be exposed to, but every time you take a shower those contaminants in the hot water volatilize, they evaporate, they enter your air space and you breathe them in.
"We certainly know that among children with leukemia in places where water contamination has been severe, and in fact we know that some of the contaminants in the water can cause leukemia in laboratory animals, that there are cases in which children have contracted leukemia whose parents always bought them bottled water. But because they flush the toilet, because they take a bath, the contaminants in the water carried to them either from groundwater wells or from reservoir water enters the air of the household and is inhaled by children.
"So this is where it's not a lifestyle issue anymore."
