The EPA has set its recommended maximum level at zero, arguing that even trace amounts of this toxic substance can harm human health.
But, some researchers maintain that small amounts of lead may be somewhat beneficial, pointing out that low levels are naturally present in surface water and certain foods.
Drinking water that contains lead can have several serious health consequences. Individuals exposed to high levels of lead in their drinking water may experience hypertension, anemia, and immune system dysfunction, which can be very dangerous.
Also, chronic exposure to lead may result in hearing loss or other neurological problems. In the most severe cases, lead poisoning can be life-threatening, as it can disrupt the normal function of vital organs like the kidneys and liver.
Reducing or eliminating any risk of ingesting lead in drinking water is extremely important. This can be accomplished by testing your water supply regularly and installing treatment systems if necessary.
