Objectives
After watching this video, you will be able to:

•   Name four health problems related to
    contaminants in drinking water

•   Identify the types of patients most sensitive to
    each health problem

•   Describe how contaminants can enter
    drinking water supplies

•   Identify the treatment methods that remove
    the contaminants

•   List clinical findings that should prompt
    reporting suspicion of a waterborne disease to
    the local health department

•   Describe how patients can learn about the
    quality of their drinking water

•   Describe the role of health care providers in
    a public health network that identifies and
    responds to waterborne illness

•   List resources for further information on
    drinking water and health

-------
Key Concepts
The following information represents some
contaminants to which certain patients may be
particularly sensitive.

Cryptosporidium parvum. Cryptosporidium
paruum is a pathogen found in human and animal
fecal waste. It can enter the rivers, lakes and
streams and rarely, ground water that contribute
to drinking water supplies. Because of it's small
size and composition, it is resistant to typical
filtration and disinfection methods—though
EPA has tightened its standards in recent years
requiring public water systems specifically to
address this contaminant.

  •  Exposure to Cryptosporidium parvum in
     drinking water may cause gastrointestinal
     problems, such as diarrhea, vomiting, and
     cramps. Patients whose immune systems
     are weakened by AIDS, chemotherapy,
     a recent transplant or other reasons are
     most vulnerable. Diarrhea and vomiting
     may cause infants and the frail elderly to
     become dehydrated more quickly. In most
     healthy adults and children, the problems
     are temporary. Other, more common
     routes of exposure to this pathogen are
     food, unsanitary diaper-changing practices,
     person-to-person-contact, and swimming in
     contaminated water.

-------
   «  Suggested interventions: Sample stools
     more frequently. Include questions on water
     sources for patients with diarrhea. Those
     with questionable water sources require
     further investigation. Most standard ova and
     parasite cultures do not automatically test
     for Cryptosporidium. Be sure to specifically
     request an acid-fast fluorescent test.

Escherichia colt or E. coli. E, coli is a type
of fecal coliform bacteria commonly found in the
intestines of animals and humans.  The presence
of E. coli in water is a strong indication of recent
sewage or animal waste contamination. Sewage
may contain many types of disease-causing
organisms. Although  most strains of E. coli are
harmless and live in the intestines of healthy
humans and animals, a particular strain, E. coli
0157-.H7, produces a powerful toxin and can
cause severe illness.

   «  Most infections of E. coJi O157:H7 are
     believed to have come from eating
     undercooked ground beef. However, some
     have been waterborne, and people have
     become sick after drinking contaminated
     water.

   •  Infection by E. coli 0157:H7 is characterized
     by severe bloody diarrhea and abdominal
     cramps, although sometimes the infection
     causes non-bloody diarrhea,  often with
     no fever. In some people, particularly
     children under 5 years of age and the

-------
     elderly, the Infection can also cause
     a life-threatening complication called
     hemolytlc luremlc syndrome, in which
     the red blood cells are destroyed and the
     kidneys fail. Hemolytic uremic syndrome is
     usually treated in an intensive care unit, and
     blood transfusions and kidney dialysis are
     often required.

   «  Suggested interventions: Encourage patients
     (or their parents) to have household well
     water tested annually  for nitrates and
     bacteria by a state-certified laboratory.  If a
     patient's well tests positive for E, coli, people
     in the household should not drink the water
     without boiling it for at least one minute
     at a rolling boil—longer if they live at high
     altitudes. The well may also be disinfected
     according to procedures recommended by
     the local health department. Water must be
     monitored periodically after disinfection to
     make certain the problem does not recur.
     If contamination is a recurring problem,
     patients should investigate the feasiblity
     of drilling a new well or installing a point-
     of-entry disinfection unit using chlorine,
     ultraviolet light, or ozone.

Disinfectants and Disinfection Byproducts
(DBPs). Disinfectants, while effective in
controlling many microorganisms, react with
matter in water to form DBPs. Unchlorinated
private well water is unlikely to contain any DBPs.

-------
   «  While health effects from exposure to
     disinfectants and DBFs vary by contaminant,
     some epidemiological studies have shown
     a link between bladder, rectal, and colon
     cancers and DBF exposure. Additionally,
     human epidemiological studies report an
     association between chlorinated drinking
     water and reproductive and developmental
     endpoints such as spontaneous abortion,
     neural tube defects, pre-term delivery,
     intrauterine growth retardation, and  low
     birth weight. In August 2003, EPA proposed
     measures beyond those already required for
     public water systems.

   •  Suggested interventions: Drinking plenty of
     water from a safe source during pregnancy
     is important. If your patients' public water
     system has notified customers of a DBF
     violation, follow instructions from the public
     water system. For example, your patients
     might want to consider alternatives to tap
     water during pregnancy.

Lead. Paint chips and dust from lead paint in
old buildings are the primary routes of children's
exposure to lead, but EPA estimates that up to
20 percent of a person's background exposure
may be due to lead in drinking water—and the
percentage is higher for infants drinking formula
mixed with contaminated drinking water. Lead
may be present in drinking water because  of
corrosion of household plumbing systems; erosion
                      10

-------
of natural deposits. In some communities, lead
service lines can also contribute to high levels of
lead in drinking water.

  •  In Infants and young children,
     continuous exposure to high levels of
     lead may result In delays In physical
     or mental development, deficits
     In attention span, and learning
     disabilities.

  «  For adults, such exposure may result in
     kidney problems or high blood pressure.

  •  Suggested interventions: Look for symptoms
     of lead poisoning in children, and test
     infants' blood lead levels. If a child's blood
     lead level is high, consider lead in tap water
     as a possible factor, in addition to lead
     paint exposure. Encourage patients to have
     drinking water tested for lead in homes,
     schools, and day care centers by a state-
     certified laboratory. Encourage local schools
     and day care centers to test their drinking
     water outlets for lead.

  *  Use only cold water for drinking, cooking,
     and especially making baby formula. It's
     important to consider that foods that absorb
     all of the water in the pot, such as rice and
     dried beans, will also absorb all of the lead
     that is in the cooking water. Soups made or
     mixed with water will also contain any lead
     that's  in the water. Foods  cooked in water
                      11

-------
     and then drained, such as pasta, meat, or
     vegetables, also absorb some lead from the
     water.

   «  If lead levels in drinking water are  high,
     consider alternatives to using boiled tap
     water in baby formula.

   «  Information and brochures are available
     from the National Lead Information Center,
     (800) 424-LEAD [5323], www.eDa.aov/lead/
     nlic.htm

Nitrates and Nitrites. Nitrates may run off
or percolate into water sources from excessive
fertilizer use and animal waste: leaching from
improperly constructed or maintained septic
tanks, cesspools, sewage; or erosion of natural
deposits.

   •  Exposure to nitrates in drinking water at
     levels above the drinking water standard
     may result in methemaglobinemia,
     or  "blue  baby syndrome" in infants
     under six months. Blue baby syndrome
     is life-threatening without immediate
     medical attention. Infants most likely to
     get methemoglobinemia are  those who are
     already sick and consume food that is high
     in nitrates, such as spinach, broccoli and
     cured meats, and drink formula mixed with
     water that is high in nitrates.
                      12

-------
   «  Possible interventions: Encourage patients to
     have household well water tested annually
     for nitrates and bacteria by a state-certified
     laboratory, especially those caring for infants
     and expectant parents and grandparents.
     If water has high nitrate levels, consider
     alternatives to using boiled tap water in baby
     formula. Boiling water only increases nitrate
     concentrations.

Drinking Water Security. Events of September
11, 2001,  have brought into focus the possibility
of intentional contamination of drinking water and
wastewater infrastructure. Doctors, nurses, and
others in primary care would likely be the first to
observe unusual illness patterns or disease trends
resulting from intentional biological or chemical
contamination.

Recognize, Report, and Prevent
Waterborne Illness

•  Report suspicion of waterborne illness to your
    local health department.

•  Take an environmental health history that
    includes, "What is the source of drinking
    water?"

•  Familiarize yourself with your patients water
    supply. Annual water quality reports are a
    good first source of information on local
    public water systems. Household well owners
    are responsible for making sure their wells are
    tested regularly and maintained properly. A
    free booklet, "Drinking Water from Household
    Wells," is available at www.epa.gou/safewater/
    oriuatewells/booklet/mdex.html.

and provided valuable critiques and advice.

Finally, thank you to all those involved, on- and
off-camera, in the production of this video.
The Milwaukee segment was filmed the week
of September 11, 2001, and the Philadelphia
and Minnesota segments were filmed just a few
weeks later. The hospitality and commitment
of our hosts, and the diligence, support, and
professionalism of the DC-based crew, made this
production possible and will not be forgotten.
