Drink Tap Water for Your Health ... and Wealth!

Water from the tap is regularly disinfected, and surprisingly, bottled water is not.

It’s difficult to pinpoint exactly when it happened, but sometime over the past decade or so, the general population of this country formed a belief that bottled water is better than tap—safer and healthier, too. It is easy to figure out where this idea originated. It was with bottled water suppliers. It was pretty ingenious to convince otherwise normal people to pay between 240 and 10,000 times more to purchase water in a bottle than to get it from the supply we’re already paying for that comes out of the taps in our homes.

Tap Water is Cheaper

These days a 16-ounce bottle of “spring” water goes for about a dollar. That’s $8 a gallon—twice the cost of milk, about on par with soft drinks purchased in the same manner. Home delivery of water in those great big, heavy bottles is less per gallon but still around $40 a month, according to online averages.

The average cost of town water for U.S. households typically ranges from $1.50 to $3 per cubic meter. This cost can vary widely depending on the location, local water utility rates and the specific pricing structure of the area. One cubic meter equals 265 gallons, or 4,240 8-ounce glasses of water—enough to last the average person 530 days (consuming eight 8-ounce glasses per day). Another way to price it: Sixty-two 8-ounce glasses of water cost about 4 cents.

Tap Water is Safer

This may startle you, but it is absolutely true: Tap water is safer than bottled water. How could that be? The reason is simple. The U.S. water supply is regulated by the Environmental Protection Agency under very strict guidelines and heavily enforced rules. Bottled water is subject to Food and Drug Administration rules, which are far less stringent. For example, tap water by law requires disinfection. Testing for bacteria must be conducted hundreds of times a month. On the other hand, bottled water is not required to be disinfected; bacteria testing is performed fewer than five times per month.

Tap Water is Healthier

Tooth decay in children is making a big comeback. The culprit? Bottled water. It’s not the water that’s causing the decay, according to the World Dental Congress. It’s the lack of fluoride. Parents believe they are giving their children a superior product in bottled water, but in fact they are depriving kids of the fluoride and minerals they need to build healthy teeth and bodies. Fluoridation, present in most public water supplies, has become recognized as a key intervention in tooth decay.
