Private
well water should be tested yearly, and in some cases more often,
according to new guidance offered by the American Academy of Pediatrics
(AAP). Researchers at the National Institute of Environmental Health
Sciences (NIEHS), part of the National Institutes of Health, took
a lead role in working with the AAP to develop these recommendations
and draft a new AAP policy statement about the things parents should
do if their children drink well water.
The
recommendations call for annual well testing, especially for nitrate
and microorganisms such as coliform bacteria, which can indicate
that sewage has contaminated the well. The recommendations point
out circumstances when additional testing should occur, including
testing when there is a new infant in the house or if the well is
subjected to structural damage.
"Children
are especially vulnerable to waterborne illnesses that may come
from contaminated wells," said Walter J. Rogan, M.D., an epidemiologist
at NIEHS and lead author on the policy statement and technical report
that appears in the June issue of Pediatrics.
The
new policy statement, "Drinking Water from Private Wells and
Risks to Children," offers recommendations for inspection,
testing and remediation of wells providing drinking water for children.
"With
few exceptions, well owners are responsible for their own wells,"
said Rogan. Private wells are not subject to federal regulations
and are only minimally regulated by states. With proper care, well
water is safe; however, wells can become contaminated by chemicals
or pathogenic organisms.
Nitrate,
which comes from sewage or fertilizer, is the most common contaminant
in wells. The presence of nitrates can be a problem particularly
for infants under three months who can not metabolize nitrate. Water
with a nitrate concentration of more than 10 milligrams per liter
should not be used to prepare infant formula or given to a child
younger than one year.
The
policy statement suggests using bottled water for infants when nitrate
contamination is detected, or when the source of drinking water
is not known.
The
policy statement and accompanying technical report point out that
water contamination is inherently local, and that families with
wells need to keep in contact with state and local health experts
to determine what should be tested in their community.
For
example, some parts of the country may have arsenic, radon, salt
intrusion or agricultural runoff that may get into the water supply.
"As
people move out of urban and suburban areas into areas that are
not reached by municipal water supplies, it is more important than
ever that people know who to contact in their local health department
to get information about local groundwater conditions," said
N. Beth Ragan of NIEHS, who served as consultant on these reports.
A compilation
of state by state telephone and Web-based resources of local experts
is included in the technical report. Approximately one-sixth of
U.S. households now get their drinking water from private wells.
NIEHS
Director Linda Birnbaum, Ph.D., says she is pleased that NIEHS researchers
took the lead in writing this statement, and continue their longstanding
liaisons with the American Academy of Pediatrics to develop state-of-the-science
technical reports that can have a direct impact on public health.
"This
statement will be extremely useful to many audiences especially
pediatricians," Birnbaum said. "Pediatricians needed a
one-stop shopping document that they can share with parents who
have concerns about their children's sources of drinking water."
