Across the country, environmentalists are waging campaigns to get people to drink more tap water, to save our environment from the scourge of up to 1.5 million tons of plastic waste generated each year by the bottled water industry. According to Food and Water Watch , that plastic requires up to 47 million gallons of oil per year to produce, and over 80 percent of plastic bottles are thrown away instead of recycled–so drinking from the tap not only saves waste and protects the environment, but helps reduce our country’s dependence on foreign oil and offshore drilling, too. So it’s pretty clear: Tap is the way to go.
But there’s a downside to drinking tap water, which is that it’s usually at least somewhat polluted—at least in the U.S. and most of the Western Europe. Some of that pollution is simply left in after insufficient purification by municipal water supply utilities, but some of it is added in by those same utilities in the name of protecting our health–fluoride (to protect our teeth) and chlorine (to kill bacteria and other organisms) are two of the most common additives. Most states require water processing plants to add both to our water, so they’re pretty much impossible to avoid. But they’re both associated with elevated risks for certain illnesses, including cancer, with the evidence for a chlorine-cancer link emerging as the strongest.
Numerous studies published in the American Journal of Epidemiology, the Journal of the National Cancer Institute and other widely respected medical journals around the world have documented a strong, significant increase in the incidence of bladder cancers among people who drink unfiltered, chlorinated tap water on a regular basis–with higher cancer rates among those who have been drinking it for the longest periods of time.
And bathing in tap water isn’t too much better. We not only absorb chlorine through our skin, but breathe it in as chloroform in the steam from a long hot shower, where it irritates our lungs and can cause asthma. Yes, chloroform is the stuff evil criminals in movies make people breathe to knock them out. And for one more scary fact, a study conducted by Dr. Niels Skakkebaek of the University of Copenhagen documented a nearly 50 percent decrease in male sperm counts in areas of Denmark where the water supply is chlorinated. Yikes.
Fortunately, however, it’s possible to enjoy the environmental (and political) benefits of using tap water and avoid the health hazards of the toxic chemicals in it, by using some form of home water filtration. A wide range of water filtration options can be found among the many other green products carried by Green Depot, ranging from simple filter pitchers to whole-house water supply filtration systems. A popular one among design junkies is the Aquaovo Ovopur system, a nifty ceramic giant egg that uses carbon, ceramics and quartz to remove not just chlorine but a host of other toxins naturally.
