Lead contamination in drinking water remains a concern in older infrastructure, highlighted by events like the Flint Water Crisis. While regulations have reduced new sources, aging pipes and fixtures can still introduce lead into tap water. Understanding how to remove lead from water and removing lead from water effectively with proven water filtration methods is key to protecting your household. If you're wondering how to remove lead from water at home, the methods below provide reliable solutions.
What Is the Best Way to Remove Lead from Water?The most effective ways to remove lead from water are reverse osmosis systems, NSF/ANSI 53-certified lead reduction rated carbon filters, and distillation. These are the most reliable methods for removing lead from water in residential settings. These water filtration methods are specifically designed to reduce or eliminate lead at the point of use, making them highly effective for removing lead from water in residential applications. Boiling water does not remove lead and may increase its concentration.

Reverse osmosis systems (NSF/ANSI 58 certified) remove dissolved lead using a semipermeable membrane
-
Lead reduction rated carbon filters certified to NSF/ANSI 53
-
Distillation removes lead by separating water from contaminants through vaporization
Yes, some older homes still use lead plumbing, and some older cities use supply lines that contain lead. Lead plumbing fixtures are more common in older homes built before the Safe Drinking Water Act was amended 1986, which prohibited the use of pipes, solder, and flux that were not lead free. Lead service lines are also more common in older cities and are usually the most significant source of lead in water according to the Environmental Protection Agency (EPA). As a result, you are still potentially at risk of lead in your tap water even if your home’s pipes contain no lead.
How Lead Gets Into Drinking WaterLead enters drinking water primarily through corrosion of plumbing materials. This includes lead pipes, service lines, brass fixtures, and solder used in older plumbing systems. When water sits in these materials—especially under certain water quality standards like low pH or low mineral content—lead can leach into the water. The EPA action level for lead is 15 parts per billion (ppb), but no level is considered completely safe.

Exposure to lead in drinking water can result in serious health effects, especially for children and pregnant women. Understanding the health risks of lead in drinking water and recognizing early warning signs is essential. Even low levels of exposure can accumulate over time.
Children:
-
Developmental delays and learning difficulties
-
Behavioral issues and attention disorders
-
Hearing and speech problems
Adults:
-
High blood pressure and cardiovascular issues
-
Kidney damage

Reproductive complications
Testing is the only way to confirm lead in drinking water, as it is odorless and tasteless. Using home water testing kits regularly supports early detection and helps guide decisions around removing lead from water. Home water test kits and certified lab testing are both viable options when removing lead from water safely.
-
Collect a first-draw sample (water that has sat in pipes for 6+ hours)
-
Collect a flushed sample after running water for 2–3 minutes
-
Use home water testing kits for initial screening
-
Send samples to a certified lab for precise measurement
Reverse Osmosis Systems
When considering how to remove lead from water, reverse osmosis systems are one of the most effective solutions available.
Reverse osmosis systems use a semipermeable membrane with extremely small pore sizes (typically around 0.0001 microns) to block dissolved contaminants like lead and other heavy metals while allowing clean water molecules to pass through. This makes reverse osmosis one of the most effective water filtration methods for removing lead from water and improving overall water quality standards.
These systems are commonly installed as under-sink lead reduction filters for dedicated drinking water filtration, but countertop reverse osmosis systems are also available for renters or homes without installation flexibility. When selecting a system, look for NSF/ANSI 58 certification to ensure it is tested for lead reduction and overall performance.
Activated Carbon Filters Rated For Lead Reduction
Another proven approach for how to remove lead from water is using properly certified lead reduction activated carbon filters. Activated carbon filters remove lead through adsorption, and with a little help from specific additives. Many homeowners choose this type of lead water filter as part of a broader strategy for removing lead from water. When selecting a lead water filter, look for NSF lead certification (NSF/ANSI 53) to ensure performance. NSF/ANSI 53-certified filters are tested to reduce lead and are commonly used in under-sink or faucet-mounted systems. Not all carbon filters qualify as a lead water filter, so certification is critical.
Distillation
Distillation works by heating water into steam and then condensing it back into liquid form, leaving contaminants like lead behind. This is another effective method for removing lead from water in smaller quantities. This method is effective but slower and typically used for smaller volumes.
Pipe Replacement
Replacing lead-containing pipes and fixtures is the most permanent solution for removing lead from water and maintaining long-term compliance with water quality standards. This approach addresses contamination at the source and supports long-term water quality standards. However, it can be costly and may not address contamination from municipal service lines.
No, boiling water does not remove lead. In fact, boiling can increase lead concentration as water evaporates and leaves contaminants behind.

FAQs: Lead in Drinking Water
What are the symptoms of having lead in your water?
Symptoms include developmental delays in children and cardiovascular or kidney issues in adults.
How does reverse osmosis remove lead from water?
It forces water through a membrane that blocks heavy metals like lead.
Does a Brita filter remove lead?
Some models do, but only those certified under NSF/ANSI 53 for lead reduction.
What are government standards for lead in drinking water?
The EPA action level is 15 ppb, but the goal is zero.
What is the cost of installing a lead removal system?
Costs vary widely from $50 for filters to several hundred dollars for RO systems.
Can I remove lead from water myself?
Yes, by installing certified filtration systems or replacing plumbing components.
Testing your water and identifying potential sources of lead—such as older plumbing or fixtures—are essential first steps when learning how to remove lead from water. Installing NSF-certified filtration, like reverse osmosis or certified carbon filters, helps reduce lead at the point of use, but ongoing monitoring is important to ensure continued protection. Explore reverse osmosis systems to find a reliable solution for how to remove lead from water in your home water supply, especially when combined with other approaches for removing lead from water.
