Title: The Truth of Water

The Truth of Water
  • Bottled Water vs. Tap Water Whats the
    difference anyway?

Sarah Shimek Duda Minnesota State University,
Mankato, Water Resources Center

Bottled Water Myth Busters
  • "If you were cool, you were drinking bottled
    water," says Ed Slade, Evian's vice president of
    marketing since 1990. "It was a status symbol.
  • no one should think that bottled water is
    better regulated, better protected or safer than
    tap," says Eric Goldstein, co-director of the
    urban program at the Natural
  • Resources Defense Council
  • (NRDC), a nonprofit organization
  • devoted to protecting health and
  • the environment.
  • Up to 40 of bottled water is
  • sourced from tap water

Healthier?
  • In 1999 the NRDC tested more than 1,000 bottles
    of 103 brands found a third of the brands
    contained bacterial or chemical contaminants,
    including carcinogens, in levels exceeding state
    or industry standards. (Thats 34 brands!)
  • Approx. 60-70 of bottled water is not regulated
    at all.
  • Contamination can come from leaching of chemicals
    in the bottles themselves.

Leave-no-trace or Muddy Boots Ecological
Footprint
  • The Fiji Water plant is a state-of-the-art
    facility that runs 24 hours a day. That means it
    requires an uninterrupted supply of electricity,
    something the local utility structure cannot
    support. So the factory supplies its own
    electricity, with three big generators running on
    diesel fuel.
  • According to his calculations, it takes about 72
    billion gallons of water a year, worldwide, just
    to make the empty bottles, says Todd Jarvis, PhD,
    associate director of the Institute for Water and
    Watersheds at Oregon State University.
  • Americas recycling rate for PET is only 23,
    which means we throw away 38 billion water
    bottles a year more than 1 billion worth of
    plastic.
  • About 1 billion bottles of water a week are moved
    around in ships, trains and trucks in the United
    States alone. That's a weekly convoy equivalent
    to 37,800 18-wheelers delivering water.

  • Bottled Water's Environmental Toll (Eco Footprint
    cont)
  • The energy used each year making the bottles
    needed to meet the demand for bottled water in
    the United States is equivalent to more than 17
    million barrels of oil. That's enough to fuel
    over 1 million cars for a year. If water and
    soft drink bottlers had used 10 recycled
    materials in their plastic bottles in 2004, they
    would have saved the equivalent of 72 million
    gallons of gasoline. If they had used 25, they
    would have saved enough energy to electrify more
    than 680,000 homes for a year. In 2003, the
    California Department of Conservation estimated
    that roughly three million water bottles are
    trashed every day in that state. At this rate, by
    2013 the amount of unrecycled bottles will be
    enough to create a two-lane highway that
    stretches the state's entire coast. In 2004
    the recycling rate for all beverage containers
    was 33.5 percent. If it reached 80 percent, the
    reduction of greenhouse gas emissions would be
    the equivalent of removing 2.4 million cars from
    the road for a year. That bottle that takes
    just three minutes to drink can take up to a
    thousand years to biodegrade.

Pennies from Heaven
  • If the water we use at home cost what even cheap
    bottled water costs, our monthly water bills
    would run 9,000.
  • Bottled water costs more ounce by ounce than
    oil, Amber Collett, Corporate Accountability
    International
  • In the U.S. combined water sewer bills average
    only about 0.5 of household income
  • National average cost of tap water is 2.00 per
    1,000 gallons, the same amount of bottled water
    would cost 8,000

12
Tap Water Just as Pure Practically Free
  • Indeed, while the United States is the single
    biggest consumer in the world's 50 billion
    bottled-water market, it is the only one of the
    top four -- the others are Brazil, China and
    Mexico -- with nearly universally reliable tap
    water.
  • Minneapolis water tested 400 1,000 times daily
  • Common treatment processes include coagulation
    (settling), filtration, and disinfection.

13
Filtered Water The Perfect Beverage?
  • 4 out of 10 Americans use a home water treatment
    unit
  • Point of Use Filters (POUs ) include filter
    pitchers, faucet filters, distillers, reverse
    osmosis units
  • Point of Entry Devices (POEs) include adsorptive
    media (carbon filters), aerators, water softeners

The Last Drop
Tap Water Regulated by EPA Bottled Water Regulated by FDA
Cannot have confirmed E. coli or fecal Coliform bacteria. A certain amount of any bacteria is allowed.
Filtered and/or disinfected No federal filtration or disinfection requirements.
Violation of drinking water standards are grounds for enforcement. Bottled water in violation of standards can still be sold.
Utilities must have their water tested by certified labs. Such testing is not required for bottlers.
Tap water results must be reported to state or federal officials. There are no reporting requirements for bottlers.
Water system operators must be certified. Bottled water plant operators do not have to be certified.
Water suppliers must issue consumer confidence reports annually. There are no public right-to-know requirements for bottlers.
Costs pennies a day Costs .80 to 4.00 per gallon.
Contains essential nutrients for the body such as calcium and iron. Natural minerals are removed by filtration.
Chlorine residual in water to prevent bacteria growth. No disinfectant present to kill bacteria in bottles.
