Transcript and Presenter's Notes

Title:


1
Back to the Tap Movement
  • David Fankhauser, PhD
  • Professor of Biology and Chemistry
  • University of Cincinnati Clermont College

2
Introduction
  • Clean water is essential for life.
  • Population pressures are leading to competition
    for water.
  • Pure, clean, safe water is everyones goal, some
    cities do this well.
  • But is bottled water better?
  • What are the real costs, both financially and to
    the environment?
  • What can I do?
  • What should we as a society do?

3
What might be wrong with tap water?
  • We flush our wastes into our rivers Out of
    sight, out of mind.
  • The America (and all of humanity) has a poor
    record on adequate treatment of waste water.
  • Many chemicals sent into the sewage waste stream
    are passed through sewage treatment.

4
Cincinnati water in the bad old days
5
Today, officially this water is treated
Major contaminants are removed in STPs. But,
for instance, is soap removed in the Nine Mile
STP? Many chemicals are resistant to standard
treatment.
6
Some pharmaceuticals are not removed by treatment
  • These pharmaceuticals
  • Antibiotics
  • anti-convulsants
  • mood stabilizers
  • sex hormones
  • These have been found in the drinking water
    supplies of at least 41 million Americans.
  • Including bottled water

7
Evidence of effects of drugs in water
  • Endocrine disrupting chemicals (EDCs) interfere
    by mimicking, blocking, or altering hormones and
    their signaling systems. An example is the
    feminization of male fish.

majority of EDCs reach aquatic environments via
effluents of sewage treatment plants.

8
In some parts of the world, bottled water makes
sense.
  • In some countries, it is wise to drink only
    bottled water.
  • But developed countries generally have high
    quality tap water.

9
NYC GREAT water
  • New York City, because of its protected
    watershed, has superb quality tap water.

10
Baltimore also protects its watershed
  • The Loch Raven Reservoir watershed is the largest
    watershed within Baltimore County.

Land use in Baltimores watershed
12
SW Ohio had a chance for pure water
The East Fork Reservoir drained low population,
non-industrialized region (but with considerable
agricultural usage). But CECOS, a mammoth
national toxic waste dump, was permitted directly
up stream Now closed, the wastes remain as a
threat.
13
What exactly IS bottled water?
  • Much bottled water is no more than filtered
    municipal tap water.
  • For instance
  • Aquafina by Pepsi-Cola
  • Dasani by Coca-Cola
  • Both municipal water

14
Pepsis original slogan for Aquafina "So pure,
we promise nothing"
  • As well they couldnt
  • A classic PR scam

15
Ironically, standards are lower for bottled water
than tap water
  • Tap water is much more strictly regulated and
    tested.
  • Water bottlers are not required to test for the
    presence of E. coli, Cryptosporidium, Giardia,
    asbestos, or certain organic compounds such as
    benzenes

16
Why is it so popular?
  • Corporate ad campaigns instill fear of tap water,
    implying that bottled water is safer
  • Status symbol (only poor or low class drink tap
    water)
  • Push for drinking 8 glasses of water a day
    (follow the money)
  • Does not taste like chlorine
  • Avoiding sugar drinks

17
Much more expensive than gasoline
So what do you pay for bottled water?
18
How absurd can we get?
  • Deep seawater from Hawaii is the most expensive
    bottled water in the world.
  • Hawaii Deep Marine Inc.s Kona Nigari water,
    sells for 33.50 per 2 oz bottle.
  • Its extracted from a depth of 915 feet, over 700
    feet more than is necessary for the water to be
    considered deep seawater.

19
And the cost to the environment?
  • Plastic manufacture, bottling, and transport all
    cost oil.
  • 86 of empties in the States are sent to landfill.

(In the orient, they are better at recycling.)
20
Any guess what we are looking at?
Hint this is five minutes worth
21
Getting closer
22
In 5 minutes 2,000,000 water bottles in US

23
Phthalates and Bisphenol A
  • PET bottles (1) are made with polyethylene
    terephthalate. Phthalates are hormone
    disrupters.
  • Bisphenol A is found in beverage bottles marked
    7 (including some baby bottles). It is an
    estrogen like compound.
  • Bottled water stored for long periods, especially
    in the heat, leach these materials into the
    water.
  • Never heat beverages in a PET container.

24
America has among the safest tap water, but
consumes most bottled water
25
A caution about home water filters
1) Place a sterile Millipore filter 2)
Attach a cylinder 3) Draw
water through with vacuum
Fresh tap water Filtered tap water
4) Place filter on nutrient pad

26
At home
  • Draw tap water and allow to breathe overnight
    to reduce chlorine. (Fill a glass gallon jug
    half full.)
  • Change filter on your water filter regularly
    (monthly?).
  • Dispose of pharmaceuticals (Incineration?
    Hazwaste? Landfill?)
  • Do not use garbage disposal, it adds to sewage
    treatment plant load.
  • Be an activist to your water works read the
    analysis reports, demand they test for
    pharmaceuticals.

27
Making the broader community Bottled Water
unfriendly
  • Insist on tap water in the US and other developed
    countries when served water.
  • Push to remove bottled water service at all
    functions government, church, business, etc.
  • Tax or require deposit on all bottles.
  • (Chicago already has a 5 cent tax/bottle.)
  • Reduce use and discharge of pharmaceuticals into
    waterways.
  • Work to make Knox Presbyterian Church Bottled
    Water Free and to promote such actions in the
    local Council of Churches, and to petition
    remedial actions by the City of Cincinnati and
    beyond.

28
Model for a petition to the church governing body
  • WHERE AS
  • Bottled water is damaging to our environment due
    to plastics used, cost of bottling, energy cost
    of transportation, the widespread litter it
    generates, and the requirements for landfill
    disposal.
  • Municipal tap water is as a rule more carefully
    regulated and at least as safe as bottled water.
  • One of the roles of the church is to be a good
    shepherd to our environment and to guide the
    community in morally responsible practices to
    this end.
  • BE IT RESOLVED
  • We the undersigned attendees of Knox
    Presbyterian Church request that the church make
    it policy to discourage the use of bottled water
    at church functions.
  • We request that Knox Presbyterian Church propose
    to the local Council of Churches that the Council
    take a stand against the use of bottled water.
