Health Information
This section provides information on potential health risks for
children exposed to lead in drinking water at school. Public Health
- Seattle & King County recommends that parents with concerns
about their child's exposure to lead should contact their health
care provider. Public Health - Seattle & King County also
offers health care services. Fees are assessed based on a family's
ability to pay, and Medicaid and Medicare are accepted. For clinic
locations and other information, call Public Health - Seattle &
King County at 206-296-4600 or visit their web site at http://www.metrokc.gov/health.
Information on Lead in
Drinking Water - Frequently Asked Questions
Seattle Public Schools engaged an independent toxicologist to
develop an information
sheet related to health risks from exposure to lead in drinking
water at Seattle Public Schools. The Information Sheet is posted on
this website. The detailed analysis of the data and conclusions
summarized in the information sheet is available in the more
extensive background
report. The document and supporting analysis was also
peer-reviewed and endorsed by a panel of independent scientists and
health experts, and findings presented in the letters.
For
all except four locations (fountains and fixtures) in the district,
analysis of the 2000 drinking water samples drawn from Seattle
Public Schools leads to these conclusions:
- The
Centers for Disease Control and Prevention (CDC) have set a level
of 10 micrograms of lead per deciliter of blood as the level below
which a child is not considered to be lead-poisoned.
-
- Based on the most
conservative (worst case) scenario, the predicted increase in blood
lead level from exposure to lead in school drinking water, for an
average 6 to11 year old child (drinking an average amount of water)
is 3.2 micrograms per deciliter (ug/dL) of blood. This included all
of the sources that had a first draw result of 670 ppb or less. The
average "background" blood lead level for children in King County,
based on exposure to all other sources, is 1.5 ug/dL. Therefore the
total predicted blood lead level is 4.7 ug/dL, which is below the
current CDC level of 10 ug/dL.
Also
based on the most conservative scenario, the predicted increase in
blood lead level from exposure to drinking water at the four
locations testing highest for lead (one each at AE II, Wedgwood,
Madison at Boren, and Roosevelt at Lincoln), the predicted increase
in blood lead level from exposure to school drinking water is
between 5.7 and 7.0 ug/dL. Therefore the predicted blood lead level
is up to 8.5 ug/dL, still below the CDC level of 10.
However, it is recommended that any parent or guardian with
concerns about this topic contact their health care provider.

Public Health
- Seattle & King County has provided the following general
information about lead exposure:
There are many
environmental sources of lead and no amount of lead is good for us,
particularly for children. Children under the age of six are most
vulnerable because they do not have a blood brain barrier formed.
Very young children also have more hand-to-mouth behavior, spend
more time on the floor where lead contaminated dust may be, and eat
more food and water per pound than do adults.
Common sources of lead
in our region include lead dust from chipping, peeling or otherwise
deteriorating paint. Homes that are much older than about 25 years
should be suspected to have lead paint in them. As long as the
paint is not deteriorating, there is no exposure.
Soil
adjacent to busy roadways may have lead deposited in it from cars
that historically used leaded gasoline. Care should be taken with
children so that they do not play in potentially contaminated dirt.
Cover dirt with grass or other plants. Carefully wash food grown in
gardens with potentially contaminated soil carefully.
Other sources of lead
in our soil include pesticide residue, and industrial sources (for
example, pollution from a Tacoma copper smelter blew over parts of
King County for almost 100 years).
Parents who work in
industries that use lead (e.g. batteries) can bring home lead on
their clothing. Some "folk" remedies involve medicines that have
lead. Candy wrappers from other countries have been found to have
lead, as has pottery.
Lead
occurs in the water, particularly when there was lead soldering
used. Running water for a few minutes before use if the water
hasn't been used flushes some of the lead out.
In
short, there are many sources of lead in our environment and
parents should take care to avoid all exposures.
If
you are concerned about your child's exposure to lead, Public
Health recommends that you discuss your child's risk with your
primary care provider. If a blood lead screening is appropriate,
your child will be given a finger stick test, not a venipuncture
(needle) test. If it comes back positive, a follow-up venipuncture
test would be advised.
