Message in a bottle: despite the hype, bottled water is neither cleaner nor greener than tap water

Andrew Swanander, owner of Mountain Town Spring Water, says, "I'm embarrassed and appalled to see my bottled water products discarded on the side of the road." In fact, a considerable number of used water bottles end up as litter where they can take up to 1,000 years to biodegrade. A 2002 study by Scenic Hudson reported that 18 percent by volume of recovered litter from the Hudson River (and 14 percent by weight) was comprised of beverage containers.

Pat Franklin, the executive director of the Container Recycling Institute (CRI), says nine out of 10 plastic water bottles end up as either garbage or litter--at a rate of 30 million per day. According to the Climate Action Network, when some plastic bottles are incinerated along with other trash, as is the practice in many municipalities, toxic chlorine (and potentially dioxin) is released into the air while heavy metals deposit in the ash. If plastics are buried in landfills, not only do they take up valuable space, but potentially toxic additives such as phthalates may leak into the groundwater. "It's ironic that many people drink bottled water because they are afraid of tap water, but then the bottles they discard can result in more polluted water," says Franklin. "It's a crazy cycle."

Franklin also acknowledges that although her group is a strong advocate of recycling, the very concept may encourage people to consume more plastics. Replacing used water bottles with new containers made from virgin resources consumes energy and pollutes the air, land and water. CRI estimates that supplying thirsty Americans with water bottles for one year consumes more than 1.5 million barrels of oil, which is enough to generate electricity for more than 250,000 homes for a year, or enough to fuel 100,000 cars for a year.

Big Footprint

Despite such a sizable environmental footprint, the push to recycle plastic water bottles has not been as successful as many consumers might like to think as they faithfully toss their used containers into those blue bins. As Utne magazine recently reported, "Despite the ubiquitous arrow symbol, only five percent of plastic waste is currently recycled in America and much of that must be fortified with huge amounts of virgin plastic." One limitation is that recycling plastic causes it to lose strength and flexibility, meaning the process can only be done a few times with any given sample.

Another problem is that different types of plastics are very difficult to sort, even though they can't be recycled together. Common plastic additives such as phthalates or metal salts can also thwart recycling efforts as can too high a ratio of colored bottles (such as Dasani's blue containers) to clear bottles. Because of the challenges, many recycling centers refuse to accept plastics. In fact, a fair amount of America's plastic recycling is done in Asia, where laxer environmental laws govern polluting factories and fuel is spent in international transport.

According to a report recently released by the California Department of Conservation (CDOC), more than one billion water bottles are ending up in the state's trash each year, representing enough plastic to make 74 million square feet of carpet or 16 million sweaters. Darryl Young, the director of CDOC, says only 16 percent of PET water bottles sold in California are being recycled, compared to much higher rates for aluminum and glass. "It's good people are drinking water, but we need to do more outreach to promote recycling," says Young.
