HOW DOES LEAD
GET INTO WATER?
Lead enters the water
("leaches") through contact
with the plumbing.
Lead leaches into water through:
• Corrosion of
- Pipes
- Solder
- Fixtures and Faucets (brass)
- Fittings
• Particles caught in aerators
Water characteristics, such as pH,
hardness and temperature, affect the
amount of leaching.
WHY SHOULD WE
TEST THE WATER?
Lead is a health risk to infants and
children.
Exposure to lead is a significant
health concern, especially for
pregnant women, young children and
infants, whose growing bodies tend to
absorb more lead than the average
adult. Drinking water is one possible
exposure route for lead. A dose of
lead can have a big effect on a little
body, especially an infant whose diet
is mostly liquid.
The longer water remains in contact
with leaded plumbing, the more
opportunity exists for lead to leach
into the water. Facilities with
prolonged periods of no water usage,
such as schools and day cares, may
have elevated lead concentrations in
the water.
Many children spend a significant
part of their days at school or in a
child care facility. The fixtures that
provide water for consumption,
including drinking, cooking lunch, and
preparing juice and infant formula,
should be tested.
Testing is the only way to confirm if
lead is present or absent.
Lead solder with more than 0.2% lead
and plumbing with more than 8% lead
were banned in 1987. Buildings did
not have to be built with certified
"lead-free" fixtures until 1997.
Even new, certified components can
leach some lead.
Water System tests do not give the
whole picture.
Most water systems test for lead as
a regular part of water monitoring.
These tests give a system-wide
picture but do not reflect conditions
at a specific drinking water outlet.

HOW DO WE
PARTICIPATE IN THE
LEAD-FREE DRINKING
WATER PROGRAM?
• Develop a sampling plan.
• Take water samples.
• Use a certified lab to analyze
water samples.
• Replace outlets with lead-
free components, as
necessary.
EPA's guidance, "Lead in Drinking
Water in School and Nonresidential
Buildings" and "Sampling for Lead in
Drinking Water in Nursery Schools
and Day Care Facilities," can help
schools and day cares achieve lead-
free drinking water. Obtain these
documents through
www.epa.gov/safewater/Pu bs.

achieve lead-free drinking water:

WHAT CAN I DO TO REDUCE LEAD
RISK AT MY HOME?
• After the water is stagnant for
several hours, flush pipes until
you feel the temperature
change before cooking,
drinking, or brushing teeth.
• Use only cold water for cooking and
drinking. Never cook or mix
infant formula using hot water.
• Have your water tested.
