4Why Nurses?
- IOM Report
- Gallup Polls
- Healthy People 2010
- Nurses, as primary health providers in the
community, must be able to field questions and
guide vulnerable populations to informed
decisions.
5Why Nurses?
- Because we get it!
- We recognize the wisdom of heeding early warnings
- We are fix it people
- We care passionately about our patients and our
communities. - We are trusted conveyors of health information to
our patients, community members, AND policy
makers - And there are a lot of us!
6What percentage of our earth is water?

8- For millions of people around the world, access
to clean and adequate water is a daily struggle. - 1.1 billion people lack access to improved water
supply.

9Facts and Figures Water and Health
- Water related diseases are killing more than 5
million people each year. - 2.3 billion people suffer from diseases linked
to dirty water. - 60 of all infant mortality worldwide is linked
to infectious and parasitic diseases, most of
them water-related. - People and the Planet UN World Water Development

12 History of Drinking Water Industrial
Agricultural Concerns
13Water Regulation
- Clean Water Act (1972)
- Safe Drinking Water Act (1978)
- Applies to all public water systems
- 1996 amendments
- source water protection,
- operator training,
- funding for water system improvements, and
- public information
14Drinking Water Standards
- Drinking water standards are regulations that EPA
sets to control the level of contaminants in the
nation's drinking water. There are two categories
of drinking water standards - National Primary Drinking Water Regulations
- MCL/MCLG
- Treatment Technique
- National Secondary Drinking Water Regulations
15Where Does Drinking Water Come From?
16Drinking Water Contaminants
- Pathogens
- Bacterial
- Viral
- Parasites
- Chemicals
- Inorganic
- Organic
- Radionuclides
- Gross alpha radiation
- Radon
17Point Source Pollution

24Contaminants of Emerging Concern in Drinking
Water Sources
- pharmaceuticals,
- synthetic fragrances,
- detergents disinfectants,
- plasticizers, preservatives,
- and others that can be present in wastewater, or
agricultural and urban runoff.

27EPA Seeks Comments on its Reevaluation of the
Chemical Perchlorate
- Most common use is in explosives and rocket
propellant - Detection in soil, surface water, and/or drinking
water wells has been reported in 49 states, DC
and Puerto Rico (DoD) - Perchlorate contamination is of concern because
- it has potential human health effects at low
concentrations - it may be widespread in the environment and
- removing it from water and soil may be costly.

29Consider an alternative source of drinking water
if
- a water advisory has been issued
- contaminant known to be in the water
- An individual is immuno-compromised

precautionary boil-water advisory for Jersey City

transmission main at the Charlotte Circle.

Centers for Disease Control and Prevention You
Can Prevent Cryptosporidiosis Drink safe
water. You may choose to take extra steps to
lower the risk of getting crypto from tap water.
These steps may take time and may cost money, so
you may want to talk about these with your
doctor. If you take these extra steps, you should
do so all the time, not just at home. Also,
remember that water and ice from a refrigerator
icemaker and drinks made at a fountain are often
made with tap water.
30Tap Water Alternatives
Boiled water Bottled water Home filtration
systems Home distillation systems
31Alternative Boiling Water
- For microbial disinfection
- Water advisories
- Vulnerable populations
- Some contaminates may be concentrated

33GAO Report Bottled Water
- evaluated the extent to which FDA regulates and
ensures the quality and safety of bottled water - evaluated the extent to which federal and state
authorities regulate the accuracy of labels and
claims regarding the purity and source of bottled
water and - identified the environmental and other impacts of
bottled water, and - conducted a state survey of all 50 states and the
District of Columbia reviewed bottled water
labels and interviewed FDA officials and key
experts. - http//www.gao.gov/new.items/d09610.pdf
34GAO Report Findings
- FDAs bottled water standard of quality
regulations generally mirror the EPAs national
primary drinking water regulations, although the
case of DEHP is a notable exception. - FDAs regulation of bottled water, particularly
when compared with EPAs regulation of tap water,
reveal key differences in the agencies statutory
authorities. - State requirements to safeguard bottled water
often exceed FDAs, but still are often less
comprehensive than state requirements to
safeguard tap water. - FDA and state bottled water labeling requirements
are similar to labeling requirements for other
foods, but the information provided to consumers
is less than what EPA requires of public water
systems under the Safe Drinking Water Act. - Regarding impacts on landfill capacity, GAO found
that about three-quarters of the water bottles
produced in the United States in 2006 were
discarded and not recycled, - Regarding the impact on U.S. energy demands, a
recent peer-reviewed article found that the
production and consumption of bottled water
comprises a small share of total U.S. energy
demand but is much more energy-intensive than the
production of public drinking water

35An EWG investigation found chemical contamination
in all bottled waters tested. The quality of the
samples varied significantly, with some bottled
waters exposing consumers to unexpectedly high
pollution load.

42Drinking Water From Private Wells and Risks to
Children
- New recommendations by the AAP call for annual
well testing - Approximately one-sixth of U.S. households now
get their drinking water from private wells. - Contaminants of concern Nitrate, Microorganisms
such as coliform bacteria, others - Circumstances when more frequent testing should
occur - new infant in the house
- well is subjected to structural damage.
- Recommendation Families with wells need to keep
in contact with state and local health experts - http//www.aap.org/advocacy/releases/june09wellwat

44- From earliest times, we and our ancestors have
depended on water as a highway, a sewer, a
pathway to discovery, a means to an empire, an
irrigator of crops - in short, as a social as
well as as chemical necessity. Chemistry,
however, remains the bottom line whatever else
we do with water, we must also drink it. - - Charles J Hitch
