Lead - why should i be concerned?
Lead in Water
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 point-of-use treatment is the most logical or practical means of filtering this contaminant. Most lead in drinking water comes from lead lined pipes, lead solder and brass plumbing fixtures inside your home. The Environmental Protection Agency (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. 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 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 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 permanent adverse health effects.
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.
