Bottled Water Found Contaminated with Medications, Fertilizer, Disinfection Chemicals
4/5/2009
Bottled water across the country contains a wide variety of toxic substances, according to laboratory tests conducted by the Environmental Working Group (EWG).
“Our tests strongly indicate that the purity of bottled water cannot be trusted,” the study authors write. “Given the industry’s refusal to make available data to support their claims of superiority, consumer confidence in the purity of bottled water is simply not justified.”
Researchers conducted comprehensive tests at the renowned University of Iowa Hygienic Laboratory on 10 leading bottled water brands, purchased from retailers in nine states and the District of Columbia (D.C.). A total of 38 toxic pollutants were detected altogether, with each brand containing an average of eight. Chemicals detected included fluoride, byproducts of chlorine-based disinfection, caffeine, pharmaceutical drugs, fertilizer residue, plasticizers, solvents, fuel propellants, arsenic, other minerals and heavy metals, and radioactive isotopes. Four brands also contained bacteria.
More than a third of the chemicals detected are not regulated by the bottled water industry. Voluntary industry standards regulate the following two-thirds, but water purchased in five states and in D.C. contained levels of some carcinogens in excess of even the industry’s standards.
