Study Finds That Bottled Water Is Same As Tap Water

By Phyllis Wheeler

An October, 2008, analysis of bottled water showed many chemical contaminants in each brand analyzed at levels no different from those in tap water.

The Environmental Working Group of Washington, DC, purchased 10 bottled water brands in nine states and the District of Columbia. A lab found traces of 38 pollutants, averaging eight pollutants per brand. In addition, four of the brands showed bacterial contamination (http://www.ewg.org/reports/bottledwater).

Two of the brands, Walmart's and Giant's store brands, were chemically indistinguishable from tap water, containing chlorine disinfectant byproducts. Giant's brand also contained fluoride. These levels of chlorine byproducts exceeded the safety standards set by the bottled water industry and the state of California.

The tests, conducted at the University of Iowa Hygienic Laboratory, revealed a variety of pollutants like caffeine and Tylenol, arsenic, radioactive isotopes, fertilizer residues nitrate and ammonia, and various other chemicals used as solvents, plasticizers, propellants, and so on.

Researchers added a test, to check the possible carcinogenic effect of estrogen-mimicking chemicals in the plastic bottles themselves. Breast-cancer cells in petri dishes flourished in one case, growing 78 percent more with one of the bottled water brands than with the control.

Americans are drinking more than nine billion gallons of bottled water yearly, at a typical cost of $3.79 per gallon. But this study shows, and the EPA points out, "Bottled water is not necessarily safer than your tap water (www.epa.gov/ogwdw/faq/faq.html). That's because the EPA sets tap water standards, and the FDA sets bottled water standards based on the EPA's tap water standards.

It seems clear that spending money on bottled water, only to get the same quality as tap water, isn't wise. Instead, let's consider a home water filter. A filter at your kitchen sink or icemaker can provide your family with plenty of clean pure water, bottled in safe containers you choose, such as stainless steel or glass. Such pure healthy water can be yours for only 8 cents per gallon.
