"In Praise of Tap Water"

Here are the hard, dry facts: Yes, drinking water is a good thing, far better than buying soft drinks, or liquid candy, as nutritionists like to call it. And almost all municipal water in America is so good that nobody needs to import a single bottle from Italy or France or the Fiji Islands. Meanwhile, if you choose to get your recommended eight glasses a day from bottled water, you could spend up to $1,400 annually. The same amount of tap water would cost about 49 cents.

Next, there’s the environment. Water bottles, like other containers, are made from natural gas and petroleum. The Earth Policy Institute in Washington has estimated that it takes about 1.5 million barrels of oil to make the water bottles Americans use each year. That could fuel 100,000 cars a year instead. And, only about 23 percent of those bottles are recycled, in part because water bottles are often not included in local redemption plans that accept beer and soda cans. Add in the substantial amount of fuel used in transporting water, which is extremely heavy, and the impact on the environment is anything but refreshing.

Tap water may now be the equal of bottled water, but that could change. The more the wealthy opt out of drinking tap water, the less political support there will be for investing in maintaining America’s public water supply. That would be a serious loss. Access to cheap, clean water is basic to the nation’s health.

From In Praise of Tap Water New York Times Editorial. (Hat tip Bill Cork. I got no problem with tap water.

Never had a problem with tap water, anyway.

. . . Ounce for ounce, it costs more than gasoline, even at today's high gasoline prices; depending on the brand, it costs 250 to 10,000 times more than tap water. Globally, bottled water is now a $46 billion industry. Why has it become so popular?

It cannot be the taste, since most people cannot tell the difference in a blind tasting. Much bottled water is, in any case, derived from municipal water supplies, though it is sometimes filtered, or has additional minerals added to it.

Nor is there any health or nutritional benefit to drinking bottled water over tap water. In one study, published in The Archives of Family Medicine, researchers compared bottled water with tap water from Cleveland, and found that nearly a quarter of the samples of bottled water had significantly higher levels of bacteria. The scientists concluded that "use of bottled water on the assumption of purity can be misguided." Another study carried out at the University of Geneva found that bottled water was no better from a nutritional point of view than ordinary tap water.

. . . Bottled water is undeniably more fashionable and portable than tap water. The practice of carrying a small bottle, pioneered by supermodels, has become commonplace. But despite its association with purity and cleanliness, bottled water is bad for the environment. It is shipped at vast expense from one part of the world to another, is then kept refrigerated before sale, and causes huge numbers of plastic bottles to go into landfills.

Of course, tap water is not so abundant in the developing world. And that is ultimately why I find the illogical enthusiasm for bottled water not simply peculiar, but distasteful. For those of us in the developed world, safe water is now so abundant that we can afford to shun the tap water under our noses, and drink bottled water instead: our choice of water has become a lifestyle option. For many people in the developing world, however, access to water remains a matter of life or death.
