How Much
Lead Is Too Much?
T he
EPA says action should be taken when lead levels reach 15 parts per
billion or higher. If tests show the lead level in your household water is
in the area of 15 ppb or higher, The EPA suggests you do as much as
possible to reduce lead levels, especially if there are young children in
the home.
What Is Lead Poisoning?
POSTED:
11:09 AM EST February 2, 2004, nbc4.com
Too much
lead can result in lead poisoning, which affects essential physical
functions. It can damage nearly every body system, including the brain,
the nervous system, and digestive tract. Lead poisoning can cause learning
disabilities, seizures, coma and even death.
Children younger than six, women of child-bearing age and those
with weakened immune systems are especially vulnerable.
The health
risks of lead include:
In
Children:
· Nervous
system damage
·
Learning disabilities
· Speech
and language problems
·
Decreased muscle development and decreased coordination
· Hearing
damage
In
Adults:
· High
blood pressure
· Nervous
system disorders
·
Digestive problems
· Memory
and concentration
· Muscle
and joint pain
In
addition, lead poisoning can pass from a pregnant woman to her unborn
fetus and can cause fetal brain damage.

How Lead Gets
Into The Water Supply
February 2, 2004
Lead in home water supplies is most frequently
tracked to the home's own plumbing. Lead in pipes or the solder that joins
pipe can leach into the water supply. Homes with copper pipes may still find
lead in the solder used to join the pipes. Brass faucets and fittings can also
contain lead. Lead can also be found in some pipes that lead from the water
treatment plant to the home.
Your home is most at risk for high lead levels
if:
your home has faucets or fittings of brass
which contains some lead
your home or water system has lead pipes
your home has copper pipes with solder and
the house is less than five years old, or you have naturally soft water, or
water often sits in the pipe Copyright 2004 by mbc4.com
Testing For Lead
February 2, 2004
You can't see, smell or taste lead in the water
supply. You should have your water tested for lead by a certified
laboratory. (Lists are available from your state or local drinking water
authority). Testing costs between $20 and $100.
Be especially suspicious if you have lead
pipes or soldering in your home.
Testing is especially important in high-rise
buildings where flushing might not work Water samples from the tap will have
to be collected and sent to a qualified laboratory for analysis.
However, be wary of "free" water testing
that is provided by the salesperson to determine your water quality; many
tests are inaccurate or misleading. Research the reputation and legitimacy
of the company or sales representative.
Protective
Action To Combat Lead
February 2, 2004
If you think your water might have lead in it, the EPA says there are
actions you can take to minimize its impact:
Use only cold water for drinking and
cooking. Hot water is more likely to flush lead from pipes and soldering.
Run water for 15 to 30 seconds before drinking, especially if
water hasn't flowed from that tap in a few hours. You must do this for
each tap you use - flushing water from the kitchen sink, won't help the
water quality coming from another room of the house.
Once you have flushed a tap, you might
fill one or more bottles with water and put them in the refrigerator for
later use that day.
Boiling water will not remove lead
A number of filters claim to reduce lead
levels in water. However, the EPA suggests you check the manufacturer's
claims and make sure they are certified by an independent agency.
NSF is one
non-profit organization that evaluates filter quality.
More information is available from the
EPA's Web site.
The EPA also supports a Safe Drinking
Water Hotline. You can reach that service by calling (800) 426-4791.
News: Water Pipe Lead Poisoning of Drinking Water
BWL to
replace lead piping to 14,000 Lansing homes
By Tom
Lambert
Lansing State Journal, July 11, 2004
Lansing's
water supplier has identified 14,000 homes with potential lead poisoning
problems and plans to replace piping going into the homes in the next 10
years.
Until Friday,
however, the Board of Water and Light had no plans to warn homeowners that
the water they are drinking could be dangerous.
Now it will.
People living in all 14,000 homes will be urged to flush their water systems
each morning and avoid drinking and cooking with hot water from their taps.
The utility has
replaced lead piping at several thousand homes over the past 12 years but
gave owners only a few weeks notice that it would go into their homes to
change the pipes - which run underground and connect to the homes' water
heaters - to copper.
But after
inquiries into the policy by the State Journal, utility officials on Friday
decided they would hold public meetings and send letters this week notifying
homeowners whether they have lead pipes. The letters won't say when the
pipes will be replaced.
When asked why
residents weren't told earlier, Sanford Novick, BWL general manager, said:
"Our position is, this isn't an immediate crisis, this is a long-term
situation. It's not like people are going to be poisoned to death starting
today."
That angers
Emily Bourne, who lives on the south side with her husband and 3-month-old
son, Aiden.
"What else
aren't they telling us?" said Bourne, who drank tap water for five months of
her pregnancy. She now uses bottled water.
Most susceptible
Those most at
risk from lead exposure are children 6 and younger and unborn children.
Prolonged exposure to lead weakens the central nervous system and can cause
learning disabilities and other problems.
The BWL has
replaced 2,000 to 3,000 lead pipes in Lansing since 1992, said Clyde Dugan,
the utility's director of special projects.
But with people
becoming more aware of the dangers of lead exposure, the utility decided
this year to step up its replacement initiative and replace the remaining
14,000 pipes over 10 years, at a cost of $30 million to $40 million.
Bill Maier, a
BWL water quality analyst, said a task force was formed in early May to
accomplish that plan.
"We are
replacing these pipes because it could be a problem down the line since they
deteriorate over time," said Maier, also a task force member. "We don't have
to do this, but we are. It's what our customers expect of us."
Citing
confidentiality concerns, the utility wouldn't release the list of the
14,000 homes affected.
The BWL put an
additional $2 million toward the project in this year's budget. In the past,
it took about $500,000 annually out of its $8 million water utilities
capital budget for the work.
The utility has
tested about 290 Lansing homes for lead exposure in the past 12 years, Maier
said. He said less than 10 percent of the tests came back with more than 15
parts per billion of lead - the limit state and federal governments have set
before a utility has to address the issue.
He wouldn't say
specifically how many homes exceeded 15 parts per billion.
Safe to drink
"Our water is
safe to drink," Maier said. "People shouldn't be worried."
Jim Cleland,
assistant chief of the state Department of Environmental Quality's water
division, confirmed that the Board of Water and Light wasn't required by the
state to replace the lead piping.
He also said
that it isn't difficult for homeowners to see if they have lead pipes going
into their homes.
"You should be
able to see the pipe coming from the outside wall and connecting to your
water meter, which is usually in the basement," he said.
Cleland added
that just because homes don't have lead pipes doesn't mean the owners are in
the clear.
"Lead is an
alloy of brass - so fixtures in your home plumbing system, which could be
faucets, valves or other connections, could lead to a problem," he said.
"People should keep that in mind."
To reduce lead in drinking water
·
Let the tap water run for at least 30 seconds to a minute before drinking
it. The more time water has been sitting in your home's pipes, the more lead
it may contain. Anytime the water in a faucet has not been used for six
hours or longer, flush the pipes by running the water until it becomes as
cold as it will get.
·
Don't use hot water from the tap for cooking, drinking or making baby
formula. Use only cold water.

Reaction Time to Fixing Lead in Schools' Water Is Disputed
By DAVID M.
HERSZENHORN
he
chairman of the State Assembly Education Committee charged yesterday
that New York State health and education officials failed to follow up
on reports that dangerous levels of lead had been detected in drinking
water at 120 schools and day care facilities.
State officials disputed the charge and said that problems had been
corrected at all but eight of the schools.
The chairman, Assemblyman Steven Sanders, said that regulators
distributed a survey in April to 684 schools and day care centers, and
that results tallied in August found that the lead levels in water from
fountains and sinks at 120 locations were high enough to require action
under federal Environmental Protection Agency guidelines.
In a blistering attack on the state's Health and Education
Departments, Mr. Sanders charged that the agencies "ignored the findings
entirely and did absolutely nothing to follow up." He also criticized
the agencies for asking schools and day care centers only whether their
lead levels exceeded the federal standard of 20 parts per billion and
not demanding the specific results.
Mr. Sanders also complained that 91 schools had checked a box on the
survey saying they needed assistance on lead in drinking water but had
received no response. He said he would pursue legislation mandating
periodic lead testing at all schools.
State officials said that Mr. Sanders was being unnecessarily
alarmist and that parents had little reason for concern. "All but a
handful of the schools identified as having levels that exceeded the
standard have taken corrective action," said William Van Slyke, a
spokesman for the Health Department. "This has actually been a
wonderfully successful effort by the two state agencies."
Mr. Van Slyke accused Mr. Sanders of grandstanding ahead of Election
Day. "This is an egregious example of election eve hysteria," he said.
Repeated exposure to hazardous lead levels can result in lead
poisoning, which can cause irreversible neurological damage, including
learning disabilities, hearing loss and other problems. Mr. Sanders, a
Democrat from Manhattan, called the agencies "shamefully negligent" for
failing to follow up on the survey and request detailed information from
schools.
State officials said the survey was distributed only to schools in
areas where questions had been raised about the public water system and
where officials would have been monitoring the situation. And they noted
that the survey asked schools: "What follow-up actions have been taken
as a result of the sampling?"
Officials said that even before the survey was distributed to 1,700
schools in April, the state had worked with federal officials to check
the water in the largest school districts, including New York City,
where 33,857 samples were taken from the city's roughly 1,200 schools.
In a letter to the Environmental Protection Agency, Michael E. Burke,
the director of the Bureau of Public Water Supply Protection, part of
the state's Health Department, reported that "in New York City,
mitigative measures were taken at outlets in 370 schools."
In Syracuse, Mr. Burke reported, 2,351 samples were taken from 370
schools, and problems were addressed at 289 outlets.
More than 400 of the state's 5,000 schools operate and maintain their
own drinking water supply and are required to test for lead.
