The Bottled Water Lie

When Antonia Mahoney moved to Boston from her native Puerto Rico 35 years ago, the first thing she noticed was how much better the water tasted. Over the years, however, the water she was receiving from her tap began to lose its appeal. "Little by little, the taste changed," says the retired schoolteacher, who eventually gave up tap water altogether and began paying over $30 a month to get bottles of Poland Spring water delivered to her house.

Walking through Boston's Copley Square on a sunny day last month, however, she was intrigued by a banner advertising something called the "Tap Water Challenge." As she approached the table, a fresh-faced activist behind it told her the "challenge" was a blind taste test to see if passersby could tell the difference between bottled water and tap water. Mahoney turned her back while four water samples were poured into small paper cups -- two of tap water from Boston and a nearby suburb, and one each of Poland Spring and Aquafina.

"That's tap water," Mahoney declared after draining the first cup. "That tastes just like what I drink at home." Her confidence faded, however, as she downed the next three, which all seemed to taste the same. When the cups were turned over, it turned out that what she thought was tap water was actually Aquafina -- and what she thought was Poland Spring was actually the same Boston tap water she gets at home for free. "I couldn't believe it, I couldn't believe it," she says later. "You know I pay so much for that water. Now I am thinking to stop the Poland Spring."

Mahoney wasn't alone in that decision. A student from Connecticut who attends Massachusetts College of Art says that she has cartons of bottled water stocked in her dorm room, because she doesn't want to chance city tap water. After taking (and flunking) the test, she says now she'll start drinking from the faucet. "It tastes the same as the tap water I drink at home in Connecticut, and I drink that all the time," says the student, Katey vanBerkum. "Why spend your money on bottled water if you don't have to."

The two are among the many who have been converted across the country over the past year by the taste test, which, if not quite as ubitquitous as the Pepsi Challenge, is equally surprising in its results. Of the hundreds of people who have participated in the Tap Water Challenge in cities including Austin, Baltimore, Minneapolis, and Philadelphia, few of them were able to identify all the samples correctly, says Gigi Kellett, who is doling out water samples this afternoon. "It's usually those who are the most die-hard or committed to a certain brand who are most surprised when they realize they can't tell the difference," she says.

Kellett is associate campaigns director at Corporate Accountability International (CAI), a nonprofit formerly known as Infact, which is best-known for its relentless crusade against tobacco companies in the 1990s. Now, the group has started a campaign to blow away perceptions that bottled water is somehow better-tasting or purer than good old H2O from the tap. At stake, they say, is the increasing commodification of a resource that should be a basic human right, not a product on sale for $1.50 at the local convenience store.
