  • What Is Lead?

    Lead is a toxic heavy metal that can cause long-term health and behavioral problems.

  • How Does Lead Get In Tap Water? 

    Lead enters drinking water through corroded plumbing materials. The most common sources are lead pipes, faucets, and fixtures.

  • Does Lead Have Any Known Health Effects?

    Lead exposure affects everyone and can cause serious health problems ranging from stomach distress to brain damage. In particular, children are at the highest risk of permanent damage from lead poisoning. Health risks of lead exposure in children include impaired development and learning, behavior, and hearing problems.

  • What Regulations Are In Place To Protect Against Lead Poisoning?

    The U.S. Environmental Protection Agency (EPA) established the Lead and Copper Rule (LCR) in 1991 in an effort to minimize and control lead contamination in water. The LCR replaced the existing maximum contaminant level (MCL) with enforceable treatment techniques that are implemented if lead concentrations were to exceed an action level of 15 parts per billion (ppb).

What Is Lead?

Lead is a metal that can be found in all parts of our environment, including in the air, soil, and water. Most of our exposure to lead comes from drinking contaminated water and proximity to lead-based paint. 

Lead exposure can lead to long-term, severe health issues and behavioral problems. It is a potent neurotoxin that can impair children’s intellectual development.

TOXICITY RATING

How Does Lead Get Into Our Water?

Lead service lines are typically the most significant source of lead in the water. In 2016, the American Water Works Association estimated that 15 to 22 million Americans are drinking water from a system with lead-based pipes.

When pipes corrode or break down, lead from the pipes can leach into the water supply. A number of factors determine the concentration of lead that enters the water, including the amount of lead the water comes into contact with, how long the water stays in the pipes, and the condition of the pipes. 

Additional water treatment chemicals can be added to our water supplies to reduce further corrosion of pipes, but the approach is only partly successful. In the long run, the only solution that addresses the main source of lead contamination in drinking water is to remove lead-based pipes and plumbing fixtures and replace them with safer alternatives.

Health Effects of Lead

Lead accumulates in our bodies over time and can cause health problems in everyone. In adults, exposure can cause severe brain and kidney damage, increase blood pressure and hypertension, and lead to reproductive issues. 

While lead poisoning is dangerous for everyone, pregnant women and children are at the highest risk. During pregnancy, lead can cross the placental barrier and expose the fetus to lead. This can result in severe effects to both the mother and the fetus and lead to reduced growth of the fetus and premature birth. 

Children are especially vulnerable to lead poisoning because their nervous system is still developing. In addition, their bodies can absorb metals at a higher rate than the average adult. At low levels of exposure, lead can impair mental development and physical growth, as well as cause behavioral problems. High levels of lead exposure can result in anemia, muscle weakness, and brain damage.     

Several agencies have recognized lead as a substance that can possibly cause cancer in humans. The Department of Health and Human Services and the EPA has determined that lead can be reasonably classified as a human carcinogenic, while the International Agency for Research on Cancer clarified that inorganic lead is likely carcinogenic, but there is insufficient information to determine whether organic lead compounds are carcinogenic.
