Bottled Water Pure Drink or Pure Hype?
Findings
1. Most bottled water apparently is of good quality, but some contains contamination; it should not automatically be assumed to be purer or safer than most tap water.
Based on available data and our testing, most bottled water is of good quality, and contamination posing immediate risks to healthy people is rare (see Chapter 3 and theTechnical Report [print report only]). However, blanket reassurances from the bottled water industry that bottled water is totally safe and pure are false.
No one should assume that just because water comes from a bottle that it is necessarily any purer or safer than most tap water. Testing commissioned by NRDC and studies by previous investigators[3] show that bottled water is sometimes contaminated. NRDC contracted with three leading independent laboratories to do “snapshot” testing (testing one to three times for a subset of contaminants of concern) of bottled water.
