How to Test for Lead in Water (and What to Do Next)
Understanding how to test for lead in water isn’t just about reacting to fear—it’s about taking smart, informed steps to protect your family. Lead contamination is often invisible and odorless, which is why so many homeowners are surprised to learn it can exist in otherwise clear, clean-tasting water. At Clean Water of Virginia, we believe that education is the first line of defense. By learning how to identify and address potential issues in your water supply, you can make confident decisions about your home’s water quality—without the guesswork or panic.
Whether you’re using an older plumbing system or simply want peace of mind, this guide walks you through the most accurate testing methods, explains what your results mean, and outlines actionable next steps. Our team is here to provide clarity, not confusion—because we care about the health and safety of every household we serve in Virginia.
Why Lead in Drinking Water Is So Dangerous
One of the most concerning things about lead in drinking water is that you won’t see, smell, or taste it—but that doesn’t mean it’s not there. Lead can quietly accumulate in the body over time, and even small amounts may contribute to serious health concerns like developmental delays in children, high blood pressure, kidney damage, and more. Both the CDC and EPA agree: no amount of lead exposure is considered safe, especially for children and pregnant women.
In many cases, lead enters the water through older plumbing systems—such as pipes, solder, and fixtures installed before 1986. But it’s important to note that lead in the local water supply can also be a factor. Homes in areas with aging infrastructure or certain water chemistry are more likely to experience corrosion that leaches lead into the water.
If you’re unsure about your home’s risk level, reaching out to your local health department can help. They often provide community water quality reports and updates on regional concerns. You can also take proactive steps by working with a local water expert. Clean Water of Virginia offers professional and personalized guidance to help protect your household. With the right information and support, you can stay ahead of potential risks and ensure your family’s water is as safe and reliable as possible.
How to Test for Lead in Water
There are four common approaches to water testing for lead:
- DIY Test Kits: Widely available at home improvement stores, these kits offer a quick and affordable way to detect the presence of lead. However, they may not provide exact measurements, and results can vary in accuracy.
- State-Certified Lab Testing: This method involves collecting a sample of your tap water and sending it to an EPA-certified lab for detailed analysis. It’s the most precise way to determine safe lead levels in tap water, typically reported in parts per billion (ppb).
- Assisted Testing with a Local Expert: A trusted local provider, like Clean Water of Virginia, can help guide the sample collection process and coordinate testing with a certified lab. While results still come from the lab, having a professional assist ensures proper procedures and accurate interpretation.
- Health Department Resources: In many areas, your local health department offers free or low-cost lead testing kits and can provide water quality information specific to your region. This can be a great starting point if you’re unsure whether lead might be a concern in your home.
For the most accurate results, it’s recommended to collect samples from multiple water sources in your home—such as the kitchen faucet, bathroom taps, and refrigerator water line. This helps capture a full picture of your home’s potential lead exposure.
Understanding Safe Lead Levels in Tap Water
The EPA’s action level for lead is 15 parts per billion (ppb), meaning utilities must take corrective action if levels exceed this threshold. However, the EPA and CDC both emphasize that no amount of lead is truly safe, particularly for young children and pregnant women.
Even trace amounts should not be ignored. If your results show anything above 1 ppb, it’s worth evaluating filtration solutions for drinking water or further testing.
What to Do If Lead Is Found
If your results reveal any amount of lead in your water, act quickly to protect your household. Here are your options:
- Use NSF-Certified Filtration: Look for filters certified to NSF/ANSI Standard 53 or 58, which are tested specifically for lead reduction. Reverse osmosis systems are especially effective for removing lead and other heavy metals.
- Flush Your Plumbing: Run cold water for several minutes in the morning to flush out stagnant water that may contain higher lead concentrations.
- Use Cold Water for Cooking and Drinking: Hot water is more likely to leach lead from pipes.
- Replace Problem Plumbing: If old pipes or fixtures are the source, consider updating them with lead-free materials.

Frequently Asked Questions
How often should I test my water for lead?
You should test your water for lead at least once a year—especially if your home was built before 1986, you use a private well, or your area has known infrastructure issues. Regular water testing helps ensure your family’s drinking water stays safe and within safe lead levels in tap water.
Can I boil water to remove lead?
No, boiling water does not remove lead. In fact, it can make the problem worse by concentrating the lead levels. To reduce lead in drinking water, you’ll need a filtration system certified for lead removal, such as those with NSF/ANSI certification.
What’s the fastest way to know if my water has lead?
The fastest and most reliable way to test for lead is to schedule a professional in-home water test. Experts like Clean Water of Virginia can help you collect samples properly and often provide same-day analysis and next-step recommendations.
What kind of water filter removes lead effectively?
The most effective filters for removing lead include reverse osmosis systems and certain high-grade activated carbon filters. Make sure your filter is clearly labeled as NSF/ANSI certified for lead reduction to ensure it meets safety standards.
