Recent ‘raw water’ movement is misguided
DEAR DOCTOR: My daughter has been talking about the merits of “raw water” — and the perils of regular tap water. Could it be that people are really drinking nonsterilized or treated water? Isn’t that dangerous?
DEAR READER:
Thanks to a recent feature story in The New York Times about several companies in the United States that are selling so-called raw water, there’s now a national conversation about this trend. The water referred to in the story is untreated, unfiltered and unsterilized. The purveyors claim it is bottled in the exact state that it emerges from certain springs, and they attach all sorts of health claims to their products.
While these companies say that the water they sell is safe for consumption (it turns out that one of these vendors, who charges upward of $20 per gallon, is actually drawing from the very same aquifer that furnishes part of Oregon with tap water at a fraction of the cost), the idea that people would seek out so-called natural water is alarming.
The truth is that securing clean drinking water has been one of the great challenges throughout history. Untreated water can contain everything from parasites, viruses and bacteria
to naturally occurring chemicals like arsenic. And while municipal drinking water certainly has its own share of black eyes, as the scandal in Flint, Michigan, has illustrated, the idea that spring water is automatically safe to drink is naive and dangerous.
According to the Environmental Protection Agency and the Centers for Disease Control and Prevention, drinking untreated water puts you at risk for any number of pathogens such as E. coli, hepatitis A, Shigella, giardia and norovirus, to name just a few. Diarrhea, cholera, dysentery, typhoid and polio are all water-borne illnesses. Add in wild-card pollutants like pesticides, farmwaste runoff, carcinogenic compounds and leakage or even spillage from septic tanks — all of which can leach into the ground miles upstream of a seemingly pristine spring — and drinking “raw” water can become a genuine health risk.
