Bottled vs. Tap Water


Bottle water costs as much as 15,000 times more than tap water.[1] In a report by the Beverage Recycling Institute, “Water, Water Everywhere: the Growth of Non-Carbonated Beverages in the US” notes that sales of plastic bottle water 1 liter and less increased more than 100 percent from 2002 to 2005[2]. The bottle water segment in the worldwide beverage industry is bottled water. This universal solvent will exceed sales of milk and coffee becoming the second most consumed beverage next to soft drinks by 2004. However, this product may contain impurities and may not live up to many of the brand labels pristine sounding names. Many bottlers just use reprocessed water from municipal water supplies.

Bottled water is big business. In 2002 worldwide sales of bottled water were $35 billion dollars. In 2002 the United States sold 7.7 billion dollars worth of bottled water showing an increase in sales of 11 percent from 2001.

While the people think this water is better than tap water this is not the case. While the names on the bottles may sound wonderful they can be misleading. According to Coop America 40 percent of bottled water comes from the tap. Also, this water may or may not be further purified depending upon the independent bottler. In 1997, the United Nations Food and Agriculture Organization stated that bottled water does not have greater nutritional value than tap water.

Ironically, municipal water system do a much more extensive job in testing water for contaminants mandated by the Environmental Protection Agency or state regulatory agencies. However, bottle water is regulated by the Food and Drug Administration and has very relaxed regulations if any. Such industry standards, monitoring and even enforcement for bottled water is largely self-regulated. This radically differs with controls placed on tap water requirements. For example if bottled water is sold within the same state it is produced then FDA does not regulate it. Most bottled water brand are sold in a single state operation and the majority states have very modest if any enforcement activity. Also testing of bottle water is significantly less than tap water. There are exceptions to this rule since states like California, New York and Texas have mandatory programs for disinfection standards to reduce possible contaminants. The Kansas Department of Health and Environment tested 80 bottled water samples from manufacturers and stores. They found that all 80 samples had detectable levels of chlorine, fluoride and sodium. 78 contained some nitrates which in large concentrations can cause blue baby syndrome. In another type of test done by a private firm, Idaho Pure Health Solutions, found that certain bacteria will grow in bottled waters after several weeks.

Another concern is that bottled water generates a lot of plastic waste. Each year 1.5 million tons of plastic are used in bottled water according to the World Wildlife Fund. It is estimated only ten percent of these plastic bottles are recycled in the US. The Container Recycling Institute estimates that American water bottles yearly consume 1.5 million barrels of oil, or enough to generate electricity to a quarter million homes for a year. Worldwide some 22 million tons of bottled water is transported from country to country impacting our air. The Container Recycling Institute cites that the overall recovery rate for drink containers was 34% in 2004, it was only 15% for custom PET bottles which includes bottled water. As sales of bottled water spirals up the amount of PET bottles being disposed of also increases.

Public drinking water supply advocates wish to address the challenges confronted by existing aged tap water infrastructure. United States EPA has accounted that 527 small water systems exist today serving 25 to 3,300 people. It estimates that the price tag to maintain these systems will cost $ 138 billion by 2014. Also it was estimated by EPA that 46,500 small systems serve only 10% of the population but will cost in the next 20 years per household $3,300. This cost is due to deferred maintenance, failure to replace or upgrade failing systems, lack of planning and insufficient rate structures to set aside funds to improve infrastructure

Some environmental advocates say the government must focus their limited resources on protecting groundwater and watersheds. However, most consumers are unaware about the quality of the expensive bottled water they purchased compared to the cost and quality of their tap water.

The PRO Zone

I was just at the US Open as their guest. My mentor, Pauline Betz Addie, was inducted in their Court of Champions, winning four times in the 1940s.  In walking around several mindless cell phone users nearly collided with me. When I realize I am mindless, I celebrate the gift of the now, also called the present. Playing tennis has been a form of meditation for me. I call  the “PRO Zone " The acronym PRO- Pause, Relax and Open helps my game — arriving fully to play tennis. By relaxing in the present, I allow the distracting “mental” weather systems to pass. This allows me to greet each new point. Increasing my concentration, I give my fullest intention to pay attention.  When I “pause” between points and slow down-- becoming more responsive and less reactive increases my concentration during play. Next, getting myself to “relax” and focusing on mentally showing up can both lessen my errors and my anxiety  My introduction to mindful tennis first began when I asked my f...

Green Spaces Provide Great Economic Potential

This is a guest column thanks to Jack Lundee - "Taking a more progressive green approach." Some of the more heavily discussed topics of early 2010 include obesity, green infrastructure, clean water, and more. In particular, the addition and/or substitution of green spaces have been quite controversial as of late. Senior resident of Urban Land Institute Ed T. McMahon states "Green space adds value to property." Not only would these areas of conservation drive economic trends upward, but they also improve the overall health of the surrounding community. For example, substituting things like golf courses with conservation areas would essentially increase surrounding property value while diminishing overpriced maintenance fees. The same holds true for airports and other large acre-eating developments. Some of these areas are already abandoned or unkempt. For instance, park and recreational areas that were once highly visited have become urban wastelands. In an articl...

Celebrate Starshine

The shortest day is upon us. This is an opportunity to celebrate the most startime.  I embrace this starlight to light my inner candle. Dance under the Milky Way, allowing the trillions of lights filtering into the trillions of cells within you.   We are all children of the stars! It is a quantum pool of loving kindness. 93% of the mass in our body is stardust originating from giant red stars by the Big Bang 5 billion years ago. We share 97% of the same atoms. All the basic elements of life, oxygen, hydrogen, carbon, calcium, and iron, were created before the earth. We share from these red giant stars more of this stardust than the asteroids or the planet Mars, All living and nonliving things on Earth, from water, crystals, rocks, stones,plants, animals, insects, birds, fish consists, of this stardust The First People are and were mystical stars watchers. These heavens are the homes of ancestors, animals, plants, and spirits.    Stargazing allows me to play with the ...
