Lead pipes once carried water into millions of American homes. Today, they are a known source of lead exposure through drinking water. Lead pipe health risks include damage to the brain and nervous system, especially in children and pregnant women. You can spot a lead pipe by its dull gray color, softness (a magnet will not stick), and a scratch test that reveals shiny silver metal underneath.
What Is A Lead Pipe Health Risks And How To Spot One
A lead pipe is a water service line made from the metal lead. Before 1986, lead was a common material for pipes because it was durable and easy to shape. The health risks come from lead that can leach into the water and then into your body. Even low levels of lead can cause lasting harm. The best way to spot a lead pipe is to look at the pipe that enters your home from the street. If it is dull gray, scratches easily with a key or coin, and a magnet does not stick to it, it is likely lead. You can also check your water utility’s records or hire a licensed plumber to confirm.
How Does Lead Get Into Your Drinking Water?
Lead does not naturally appear in water sources. It enters the water when lead pipes or lead solder inside pipes corrode. Corrosion happens more quickly when the water is acidic or has low mineral content. Water that sits in lead pipes for several hours, such as overnight, tends to have higher lead levels. The U.S. Environmental Protection Agency (EPA) has set an action level of 15 parts per billion (ppb) for lead in public drinking water, but no level of lead is considered completely safe.
Who Is Most at Risk From Lead in Water?
Children under the age of six are at the highest risk. Their growing bodies absorb lead more easily, and lead can harm their developing brains. Pregnant women are also at increased risk because lead can cross the placenta and affect the fetus. Adults with high blood pressure or kidney disease may face additional risks from lead exposure. The CDC’s blood lead reference level is 3.5 micrograms per deciliter (µg/dL), and any child with a blood lead level above that is considered exposed to a level of concern.
What Health Problems Can Lead in Water Cause?
Lead affects nearly every system in the body. In children, long-term exposure can cause learning disabilities, lower IQ, attention problems, and behavioral issues. In adults, lead can raise blood pressure, damage the kidneys, and reduce fertility. Very high levels of lead can cause anemia, abdominal pain, and nerve damage. The effects of lead are often permanent, which is why prevention is critical.
How Can You Test for Lead in Your Water?
The only reliable way to know if your water contains lead is to have it tested by a certified laboratory. Your local water utility should provide information about lead testing. The utility may also offer free test kits. If you have a lead service line, the water utility is required under EPA rules to notify you. You can also buy a home test kit, but these are less accurate than lab tests. The most accurate method is to collect a first-draw sample from a faucet that has not been used for at least six hours and send it to a state-certified lab.
What Should You Do If You Have Lead Pipes?
If you confirm you have lead pipes, the most effective step is to replace them fully. Partial replacement can actually increase lead levels temporarily. While you wait for replacement, you can reduce your risk by using only cold water for drinking, cooking, and making baby formula. Run the water for one to two minutes before using it if the faucet has not been used for several hours. A certified water filter that removes lead can also help, but make sure the filter is specifically rated for lead reduction. Boiling water does not remove lead; it concentrates it.
How Are Lead Pipes Being Replaced Across the United States?
The Lead and Copper Rule, updated in 2021, requires water systems to inventory their lead service lines and develop plans to replace them. Many cities are working to replace all lead pipes, but the process is slow and expensive. Federal funding through the Bipartisan Infrastructure Law has allocated billions of dollars toward lead pipe replacement. Homeowners are often responsible for the portion of the pipe on their property, though some utilities and local programs offer assistance. If you own an older home, check with your water utility about replacement programs.
Frequently Asked Questions
How can I tell if my water pipes are lead?
Look at the pipe that enters your home from the ground. Lead pipes are dull gray and scratch easily with a coin, revealing a shiny silver line. A magnet will not stick to lead pipes.
Is it safe to drink water from lead pipes if I run the tap first?
Running the tap for one to two minutes reduces lead levels, but it does not eliminate risk entirely. The safest solution is to replace the lead service line.
What is the health risk of lead in water for adults?
In adults, lead can raise blood pressure, damage the kidneys, and reduce fertility. Long-term exposure may also increase the risk of cognitive decline.
Do water filters remove lead from tap water?
Some water filters certified to NSF/ANSI Standard 53 for lead reduction can remove lead. Check the label to be sure. Boiling water does not remove lead.
