What to Do After Testing Positive for Lead in Water

Discovering that your drinking water contains lead can be an unsettling experience. Because lead is an invisible, odorless, and tasteless contaminant, its presence often goes unnoticed until a test reveals it. However, receiving an elevated result is not necessarily a cause for panic—it is a call to action. With the right information, you can effectively manage the risk and protect your household.

If your recent test results show lead levels above zero, here is a practical guide on how to respond, minimize your exposure, and find long-term solutions.

1. Take Immediate “Stop-Gap” Measures

If you have received a positive test result, your priority is to reduce immediate exposure. You do not need to stop using your home’s water entirely, but you should change how you interact with it.

  • Switch to Cold Water: Lead dissolves more easily in warm or hot water. For drinking, cooking, and preparing baby formula, always use cold, flushed water. Do not use hot tap water, as it is much more likely to contain higher concentrations of leached lead. YouTube+ 1
  • Boiling Won’t Help: A common misconception is that boiling water makes it safe. Boiling does not remove lead; in fact, as some water evaporates during the boiling process, it can actually increase the concentration of lead remaining in the pot. EPA+ 1
  • Flush the Pipes: If the water has been sitting stagnant for several hours (like overnight or while you were at work), run the cold water for 3–5 minutes before using it. This flushes the water that has been in contact with your internal plumbing and brings in fresh water from the municipal main. EPA+ 1

2. Identify the Source

Lead in drinking water usually comes from one of three places: the service line, your home’s internal plumbing, or your fixtures. Identifying the culprit is key to solving the problem.

Head Start

  • Check the Service Line: The pipe connecting your home to the water main in the street may be made of lead. Contact your local water utility; they often keep records of known lead service lines and may have replacement programs in place. EPA+ 1
  • Inspect Your Fixtures: Sometimes, the source is simply an older brass faucet or valve. Even “lead-free” fixtures installed years ago may contain enough lead to affect your water quality. Replacing these fixtures with modern, certified “lead-free” options is often a quick and effective fix. Head Start
  • Professional Assessment: If you are unsure where the lead is coming from, consider hiring a licensed plumber. They can inspect your home’s plumbing and help you determine if you have lead solder, lead pipes, or specific fixtures that need replacing. NRDC

3. Utilize Certified Filtration

If you cannot immediately replace your pipes, a point-of-use (POU) water filter is an excellent interim or long-term solution.

  • Look for Certification: Not all filters remove lead. Ensure the filter is certified by NSF/ANSI Standard 53 specifically for lead reduction. You can check the packaging or the manufacturer’s website for this specific certification. Environmental Hazards Services LLC+ 1
  • Placement Matters: Whether you use a pitcher filter or a faucet-mounted unit, follow the manufacturer’s maintenance schedule strictly. A filter that is not changed on time can lose its effectiveness. ArcGIS Experience Builder
  • Other Options: If you prefer, high-quality bottled water is a safe, short-term alternative for drinking and preparing baby formula until your plumbing issues are addressed. NJDEP – NJ.gov

4. Consult the Experts

You do not have to navigate this alone. Many resources are available to help you interpret your results and plan your next steps.

  • Contact Your Water Utility: Many utilities provide free or subsidized testing and can offer guidance on the specific infrastructure in your neighborhood. EPA
  • Health Department Guidance: If you have young children or pregnant members in your household, reach out to your local health department. They can provide information on blood lead testing to ensure your family’s health hasn’t been compromised. NJDEP – NJ.gov
  • Deepen Your Knowledge: If you are still trying to piece together what your results mean, our FAQ section covers common questions regarding lead thresholds and safety. For those interested in the underlying science, revisiting how lead testing works can help you understand the nuances of your specific sample results.

5. Long-Term Remediation

If your test results consistently show high levels, you should aim for a permanent solution. This might involve:

  • Plumbing Replacement: If your home is one of the many lead in older buildings, consider replacing older lead-soldered pipes or fixtures.
  • Service Line Replacement: If your service line is the source, coordinate with your utility for a full replacement. Avoid “partial” replacements, which can sometimes temporarily spike lead levels. NJDEP – NJ.gov+ 1

Moving Forward

The most important takeaway is that you have options. Testing your water is the first step toward taking control of your environment. While a positive result can be stressful, it is simply a data point that allows you to make an informed decision about the health of your home.
