Lead Poisoning: What You Should Know

Lead is the number one environmental health threat to our children.

Next to chlorine, lead is the most common contaminant found in tap water. Lead in drinking water usually originates
between the water main in the street and the household faucet, so treatment from a central point is neither logical
or practical.

Most lead in drinking water comes from lead lined pipes, lead solder and brass plumbing fixtures inside
your home. The EPA estimates that 98% of all homes have pipes, fixtures or solder joints in the household plumbing
that can contribute some level of lead to the tap water.

It has been determined and recognized by the EPA that there is no safe level for lead in drinking water and that
any level poses some degree of adverse health effects.

Ironically lead takes it’s greatest toll on small children. Even very low levels of lead can cause reduced IQs,
learning disabilities and behavioral problems such as hypertension and reduced attention span in children. And often
the effects of lead are life long and irreversible.

In adults lead in drinking water causes high blood pressure and reduces hemoglobin production necessary for oxygen
transport and interferes with normal cellular calcium metabolism. Water borne lead effects every one in a very tragic
and permanent way. Lead exposure is cumulative and long lasting. This toxic metal is stored by the body, primarily
in teeth and bones. When the body is under physical stress, or deficient in certain minerals, the stored lead is
released in varying quantities depending on the individuals physical state.

Essentially, lead has a very damaging effect on the body’s electrical system, the nervous system. It causes the
critical life giving messages, sent from the brain to every cell and organ in our body, to become distorted. This
results in the onset of a chain of tragic health effects.

It is estimated by the U.S. EPA that lead in drinking water contributes to 560,000 cases of learning disorders in
children and 680,000 cases of hypertension in adults, each year in the U.S. alone. Some studies have even shown a
relationship in exposure to lead and adolescent crime. Areas in large cities that have shown to have higher levels
of lead in the drinking water, have also been found to have a higher rate of pre-adult crime. The effects of lead
in drinking water; depression, anxiety, learning disabilities and hypertension are many of the same factors that
lead to anti-social behavior and in some cases violent activities in children and teenagers.

In the first quarter of 1993, the EPA released a first-time report that showed the results of the new test at the
tap requirements for lead in drinking water. The report documented that, in America, 42 states exceeded the legal
limits of lead in drinking water and that other states failed to do the required testing. Some areas had lead levels
in excess of 450 parts per billion, thirty times the legal limit of 15 ppb. The level the EPA has set as the safe
level, or MCLG (maximum contaminant level goal), is 0 ppb.

The U.S. EPA has also found that in adult males, better control over lead in drinking water could prevent over 680,000
cases of hypertension, 650 strokes, 880 heart attacks, and 670 premature deaths from heart disease every year in
America alone.

In 1991, the U.S. EPA lowered the federal standard for the allowable level of lead in drinking water from 50 ppb
(parts per billion) to 15 ppb. This new standard was an improvement, but according to the Natural Resources Defense
Council, was in violation of federal law. The law requires EPA to set Maximum Contaminant Levels based on “health
effects” and not economic feasibility. Even though research presented to the EPA documented that there is NO
safe level for lead in drinking water, and that any level poses certain adverse health effects, the allowable level
was set at 15 ppb after an intense lobbying effort by the water utilities. EPA’s new standard also gave water utilities,
that were out of compliance, up to 20 years to comply.

Essentially, every household with indoor plumbing has some level of lead in the tap water that represents a health
risk. The biggest tragedy of lead contamination from drinking water is that it is completely preventable. By taking
a few simple steps, beginning with Point-Of-Use filtration of our drinking water, we can virtually eliminate the
crippling effects of lead on our society, and most importantly on our children.
