To a Friend

It's a rare day that Kelly Harrison, a mother of five from Tulsa, Okla., doesn't find herself chauffeuring kids to some kind of sports practice or school activity. As she checks to see that each child is seat-belted into the family's minivan, Harrison also makes sure they've got the essentials: the right sports equipment, the right clothes, and what she considers to be the right drink--bottled water.
When she was growing up, Harrison, 34, might have grabbed a soft drink or juice on her way out the door. But for her kids, Harrison insists on what she thinks is a healthier choice--water. She says her children's young bodies need water as they play in the Oklahoma sun. Bottled water also contains no caffeine, no calories and no sugar. Plus, bottled water comes in convenient bottles, easy to tote from home to wherever the busy family goes. [See what Americans are drinking in 2002.]
"I really think this is best for a lot of different reasons," says Harrison, who often tucks a bottle for herself into the basket in her minivan that contains other on-the-go mom necessities, such as a paperback book and her cell phone.
Once, most Americans got their water only from the tap. Now, like Harrison, they're often buying their water in a bottle. At work, after a workout, or just about any time, Americans are drinking bottled water in record numbers--a whopping 5 billion gallons in 2001, according to the International Bottled Water Association (IBWA), an industry trade group. That's about the same amount of water that falls from the American Falls at Niagara Falls in two hours.
Explosive growth in the industry for more than a decade has placed bottled water in nearly every supermarket, convenience store and vending machine from coast to coast, where dozens of brands compete for consumers' dollars. In four years, industry experts anticipate that bottled water will be second only to soda pop as America's beverage of choice.
Water, of course, is essential to human health. Drinking enough water to replace whatever is lost through bodily functions is important. But surveys indicate that most of us might not be drinking enough. Is bottled water part of the answer? To decide, consumers need to arm themselves with knowledge about what they're buying before they grab the next bottle of Dasani, Evian or Perrier off the shelf. "It really pays to do your homework," says Stew Thornley, a water quality health educator with the Minnesota Department of Health.
Bottled water may seem like a relatively new idea--one born during the heightened awareness of fitness and potential water pollution during the last two or three decades. However, water has been bottled and sold far from its source for thousands of years. In Europe, water from mineral springs was often thought to have curative and sometimes religious powers. Pioneers trekking west across the United States during the 19th century also typically considered drinkable (potable) water a staple to be purchased in anticipation of the long trip across the arid West.
Today, of course, there are dozens of brands of bottled water and many different kinds, including flavored or fizzy, to choose from.
The Food and Drug Administration regulates bottled water products that are in interstate commerce under the Federal Food, Drug, and Cosmetic Act (FD&C Act).
Under the FD&C Act, manufacturers are responsible for producing safe, wholesome and truthfully labeled food products, including bottled water products. It is a violation of the law to introduce into interstate commerce adulterated or misbranded products that violate the various provisions of the FD&C Act.
The FDA also has established regulations specifically for bottled water, including standard of identity regulations, which define different types of bottled water, and standard of quality regulations, which set maximum levels of contaminants (chemical, physical, microbial and radiological) allowed in bottled water.
From a regulatory standpoint, the FDA describes bottled water as water that is intended for human consumption and that is sealed in bottles or other containers with no added ingredients, except that it may contain a safe and suitable antimicrobial agent. Fluoride may also be added within the limits set by the FDA.
Is the extra expense of bottled water worth it? One thing consumers can depend on is that the FDA sets regulations specifically for bottled water to ensure that the bottled water they buy is safe, according to Henry Kim, Ph.D., a supervisory chemist at the FDA's Center for Food Safety and Applied Nutrition, Office of Plant and Dairy Foods and Beverages. Kim, whose office oversees the agency's regulatory program for bottled water, says that major changes have been made since 1974, when the Safe Drinking Water Act (SDWA) first gave regulatory oversight of public drinking water (tap water) to the U.S. Environmental Protection Agency (EPA). Each time the EPA establishes a standard for a chemical or microbial contaminant, the FDA either adopts it for bottled water or makes a finding that the standard is not necessary for bottled water in order to protect the public health.
"Generally, over the years, the FDA has adopted EPA standards for tap water as standards for bottled water," Kim says. As a result, standards for contaminants in tap water and bottled water are very similar.
However, in some instances, standards for bottled water are different than for tap water. Kim cites lead as an example. Because lead can leach from pipes as water travels from water utilities to home faucets, the EPA set an action level of 15 parts per billion (ppb) in tap water. This means that when lead levels are above 15 ppb in tap water that reaches home faucets, water utilities must treat the water to reduce the lead levels to below 15 ppb. In bottled water, where lead pipes are not used, the lead limit is set at 5 ppb. Based on FDA survey information, bottlers can readily produce bottled water products with lead levels below 5 ppb. This action was consistent with the FDA's goal of reducing consumers' exposure to lead in drinking water to the extent practicable.
Production of bottled water also must follow the current good manufacturing practices (CGMP) regulations set up and enforced by the FDA. Water must be sampled, analyzed and found to be safe and sanitary. These regulations also require proper plant and equipment design, bottling procedures and recordkeeping.
The FDA also oversees inspections of the bottling plants. Kim says, "Because the FDA's experience over the years has shown that bottled water poses no significant public health risk, we consider bottled water not to be a high risk food." Nevertheless, the FDA inspects bottled water plants under its general food safety program and also contracts with the states to perform some bottled water plant inspections. In addition, some states require bottled water firms to be licensed annually.
Members of the IBWA also agree to adhere to the association's Model Code, a set of standards that is more stringent than federal regulations in some areas. Bottling plants that adopt the IBWA Model Code agree to one unannounced annual inspection by an independent firm.
The FDA also classifies some bottled water according to its origin.
Bottled water may be used as an ingredient in beverages, such as diluted juices or flavored bottled waters. However, beverages labeled as containing "sparkling water," "seltzer water," "soda water," "tonic water," or "club soda" are not included as bottled water under the FDA's regulations, because these beverages have historically been considered soft drinks.
Some bottled water also comes from municipal sources--in other words--the tap. Municipal water is usually treated before it is bottled.
Examples of water treatments include:
Bottled water that has been treated by distillation, reverse osmosis, or other suitable process and that meets the definition of "purified water" in the U.S. Pharmacopeia can be labeled as "purified water."
Whether bottled water is better than tap water, and justifies its expense, remains under debate. Stephen Kay, vice president of the IBWA, says member bottlers are selling the quality, consistency and safety that bottled water promises, and providing a service for those whose municipal systems do not provide good quality drinking water.
"Bottled water is produced and regulated exclusively for human consumption," Kay says. "Some people in their municipal markets have the luxury of good water. Others do not."
Thornley, of the Minnesota Department of Health, agrees that consumers can depend on bottled water's safety and quality. But he says consumers should feel the same way about the quality of their tap water. Tap water may sometimes look or taste differently, he says, but that doesn't mean it's unsafe. In fact, the most dangerous contaminants are those that consumers cannot see, smell or taste, he says. But consumers don't need to worry about their presence, he adds. Municipal water systems serving 25 people or more are subject to the federal Safe Drinking Water Act. As such, the water constantly and thoroughly tested for harmful substances, he says. If there is a problem, consumers will be warned through the media or other outlets.
"In lieu of being told otherwise, consumers should feel confident of the safety of their water," Thornley says.
Dr. Robert Ophaug, a professor of oral health at the University of Minnesota School of Dentistry, notes that tap water has another advantage many people don't think about: It typically contains fluoride. Many communities have elected to add fluoride to drinking water to promote strong teeth and prevent tooth decay in residents, though some groups continue to oppose this practice and believe it's detrimental to health.
Ophaug says bottled water often does not have fluoride added to it. Or, if it has been purified through reverse osmosis or distillation, the fluoride may have been removed. People who drink mostly bottled water, especially those who have children, need to be aware of this, he says. They may need to use supplemental fluoride that is available by prescription from dentists or doctors. The supplements are usually recommended for children ages 7 to 16. Fluoride supplements cost around $15 for a three-month supply.
"At the least, inform the children's dentist or doctor that you are relying on bottled water," Ophaug says.
The IBWA says there are more than 20 brands of bottled water with added fluoride available to consumers today. When fluoride is added to bottled water, the FDA requires that the term "fluoridated," "fluoride added," or "with added fluoride" be used on the label. Consumers interested in how much fluoride bottled water contains can usually find out by contacting individual companies directly.
Consumers don't appear ready to give up their bottled water any time soon. Younger, health-oriented people are driving the market's growth, according to industry officials. "They've grown up with bottled water, and it doesn't seem like such a stretch to them to buy water," says Kay.
Jeremy Buccellato, 31, of Ramsey, Minn., says he's heard the arguments that tap water is just as good if not better than bottled water. A glass from his own tap, however, provides water that's discolored, chlorinated, and tastes like "pool water." Buccellato says the extra money he spends on bottles of Dasani water is worth it.
"It tastes better and looks better, plus it's easy to take with me," says Buccellato. "What's not to like?"
Harrison agrees that there's nothing like a refreshing cool bottle of water to beat the heat during an Oklahoma summer.
"It's a product that fits our needs and our lifestyle," she says.

Consumers can buy purified water. They also have the option of doing it at home.
Numerous companies sell filtration systems. Some attach to the faucet and filter the water as it comes through the tap. Others are containers that filter the water in them. Among the best-known manufacturers are PUR and Brita.
Water purified with these products typically costs less than buying bottled water. According to Brita, its high-end faucet filter system provides water for 18 cents a gallon, a considerable saving from $1 or more typically charged for an 8- to 12-ounce bottle of water.
John B. Ferguson, communications manager/executive editor with the Water Quality Association, says that consumers can feel confident about the water quality provided by brand name home-filtration systems.
Stew Thornley of the Minnesota Department of Health agrees that home filtration systems can improve the taste or appearance of tap water at a minimal cost. However, Thornley points out that consumers need to be careful about maintaining these filters. Typically, specific instructions are included with the purchase of the product. Without proper maintenance, he says, it's possible bacteria or other contaminants can build up in the products.
