Lead is a potent neurotoxin that has been recognized for decades as a significant public health threat, particularly to children. Because children are still in the critical stages of physical and neurological development, their bodies are uniquely vulnerable to the effects of lead exposure.
In older cities like New York, where historic building infrastructure may contain legacy lead plumbing, understanding the risks is a vital responsibility for parents, guardians, and property managers.
Why Children Are More Vulnerable
Children are at a higher risk of lead poisoning than adults for several key reasons, which makes regular lead testing for drinking water in Brooklyn brownstones and older residential buildings crucial for parents:
- Rapid Absorption: A child’s body absorbs lead from the environment at a much higher rate than an adult’s.
- Developing Brains: A child’s nervous system is constantly growing. Lead interferes with the development of synapses and the nervous system, which can cause permanent damage to brain function.
- Hand-to-Mouth Behavior: Young children are naturally curious and frequently touch surfaces or objects, then place their hands or toys in their mouths, increasing their risk of ingesting lead particles found in dust, soil, or water.
- Low Body Mass: Because children are smaller, even small amounts of lead represent a much higher concentration relative to their total body mass compared to an adult.
The Health Consequences of Lead
The effects of lead exposure in children are often irreversible. Because these impacts can be subtle, they may not be immediately obvious, making prevention the only truly effective strategy.
- Cognitive Delays: Exposure is linked to lower IQ scores, reduced attention span, and learning disabilities.
- Behavioral Issues: Research has shown associations between lead exposure and increased hyperactivity, impulsivity, and aggressive behavior.
- Developmental Challenges: It can affect physical growth, hearing, and the ability to process information.
- Anemia: High levels of lead can interfere with the body’s ability to produce hemoglobin, the protein in red blood cells that carries oxygen.
Lead in Drinking Water: The Invisible Risk
While lead-based paint and contaminated soil are well-known hazards, lead in drinking water is a frequent, silent contributor to childhood exposure. Lead does not have a taste, smell, or color, so a child can be drinking contaminated water without anyone knowing.
Lead enters the water supply when water reacts with old plumbing components—specifically lead service lines, lead-based solder used to join copper pipes, and outdated brass fixtures. When water sits stagnant in these pipes overnight, it can accumulate lead.
Why You Cannot “See” the Danger
Because you cannot see lead, professional water testing is the only way to know if your home’s water is safe. Relying on visual checks or municipal water reports is not enough, as these cannot account for the specific condition of your building’s internal plumbing.
How to Protect Your Children
If you live in an older home, you can take immediate, proactive steps to minimize the risk of exposure:
- Test Your Water: Use an accredited laboratory to perform professional water testing. This gives you a clear, scientific baseline.
- The “First-Draw” Protocol: Always flush the cold water tap for at least 30 seconds to 2 minutes before using it for drinking, cooking, or preparing baby formula, especially if the water has been sitting in the pipes for several hours.
- Use Cold Water Only: Never use water from the hot water tap for drinking or cooking. Hot water is more aggressive and dissolves lead from pipes and fixtures much faster than cold water.
- Install NSF-Certified Filters: If tests show the presence of lead, install an NSF-certified point-of-use filter specifically designed to remove lead.
- Clean Aerators: Periodically clean the aerators (the small mesh screen at the tip of your faucet) to remove trapped lead particles or sediment.
Taking Action with Confidence
Securing your home environment is one of the most important things you can do for your family’s long-term health. If you are concerned about lead, do not rely on guesswork. Using the correct lab methods provides the precision needed to understand your risk and take informed action.

If your home was built before 1986, have you ever taken the step to have your kitchen tap water professionally tested for lead?
