How to Remove Lead From Drinking Water
Lead contamination in drinking water is a serious issue that many homeowners face, often without realizing it. Unlike other contaminants, lead typically doesn’t originate from the water source itself. Instead, it leaches into your water from aging plumbing materials such as lead service lines, brass fixtures, and old solder connections. Because there is no safe level of lead in drinking water, especially for infants and pregnant women, understanding how to detect and effectively remove it is crucial for protecting your family’s health.
What Causes Lead in Drinking Water?
Lead contamination occurs primarily when water interacts with plumbing that contains lead. The US still has an estimated 9.2 million lead service lines in use, with the highest concentration in states like Florida, Illinois, and Ohio. These pipes connect the water main in the street to your home’s plumbing and over time, lead can leach into the water passing through them. Inside the home, brass fixtures and older solder may also release lead particles into your tap water, especially if the water has been sitting unused for several hours.
It’s important to note that lead typically does not come from the water source or municipal supply but from your home’s plumbing system. This means that even if your city water meets all safety regulations, lead exposure can still occur right at your kitchen tap.
Signs and Health Impacts of Lead in Water
Lead exposure through drinking water can cause severe health problems. It is particularly dangerous for infants, young children, and pregnant women because it can affect brain development, lead to lower IQ, behavioral issues, and other serious health conditions. Adults can also suffer from high blood pressure, kidney damage, and reproductive problems.
Unfortunately, lead-contaminated water usually has no taste, color, or smell, making it impossible to detect without proper testing. Some indirect signs can include blue-green staining around faucets or a metallic taste in the water, but these are not always present.
How to Reduce Lead in Drinking Water
The first step to addressing lead in your drinking water is to get your water tested, preferably by a certified laboratory. You can also contact your water utility to ask whether your home is served by a lead service line. If lead is present, there are effective treatment options you can use to reduce your exposure:
- **Flush your taps:** After water has sat in pipes for several hours (like overnight or during work hours), flush your taps by running cold water for 30 seconds to 2 minutes before drinking or cooking. Avoid using hot tap water for cooking or infant formula preparation, as hot water dissolves lead more quickly.
- **Use certified point-of-use treatment:** For reliable lead removal, install treatment devices certified specifically for lead reduction at your kitchen tap. These include Reverse Osmosis (RO) systems and lead-certified carbon block filters.
- **Avoid water softeners:** It’s important to understand that water softeners do not remove lead. If you rely solely on a water softener, lead contamination may still be an issue.
Installing a high-quality Reverse Osmosis system is among the most effective ways to reduce lead. An RO system uses multiple filtration stages to remove lead and other contaminants, giving you peace of mind with every glass of water.
How to Choose and Size a Lead Removal System
When selecting a lead removal system, consider the following:
- **Certification:** Ensure the system is NSF certified for lead reduction.
- **Point-of-use installation:** Focus on filtering water where you drink and cook, typically under the kitchen sink. This approach targets the water you consume directly.
- **Capacity and flow rate:** Look at the system’s daily output and if it can keep up with your household’s water usage while maintaining peak filtration performance.
- **Maintenance:** Regular filter changes are essential to keep the system functioning properly and effectively removing lead.

FAQ
How can I tell if my home has a lead service line?
Contact your local water utility and ask if your home is serviced by a lead line. Some utilities maintain maps or databases identifying lead service lines. You can also have your water tested for lead to determine if lead is present.
Is boiling water a good way to remove lead?
No. Boiling water does not remove lead; in fact, it can concentrate lead levels as water evaporates. Use certified filtration systems instead.
Why shouldn’t I use hot tap water for cooking or making baby formula?
Hot water dissolves lead from plumbing materials more quickly than cold water, increasing the risk of ingestion. Always use cold water that has been properly flushed and filtered for cooking and infant formula preparation.
Can a water softener remove lead from my water?
No, water softeners do not remove lead. They are designed primarily to remove hardness minerals like calcium and magnesium. To remove lead, you need specialized treatment such as Reverse Osmosis or a certified carbon block filter.
