emoving lead from drinking water naturally can be a bit tricky because lead is a toxic metal that dissolves into water, often from old plumbing pipes or fixtures. While there are no purely natural methods that are 100% effective on their own, certain approaches can help minimize lead exposure or reduce lead in water, often in conjunction with filtration systems. Here’s how you can reduce or remove lead from drinking water:
1. Use a Water Filter Certified for Lead Removal
One of the most effective methods to naturally remove lead from drinking water is using a filter designed to specifically target lead. While filters themselves are not “natural,” they provide a passive, non-chemical solution.
Look for Filters with NSF/ANSI Certification:
- NSF/ANSI Standard 53: Certified for lead reduction.
- NSF/ANSI Standard 58: Reverse osmosis filters (RO) that remove lead.
Types of Filters That Work:
- Activated Carbon Filters: These filters, especially if designed for lead, can trap lead particles. They’re found in pitchers, faucet filters, and whole-house systems.
- Reverse Osmosis Systems: RO systems use a semi-permeable membrane to remove lead and other contaminants. This is one of the most effective methods for lead removal.
- Distillation Systems: Distillers boil water and collect the steam, leaving lead behind.
Natural Option:
- Carbon-based filters use coconut shell carbon, a more natural filtering medium that can be effective for lead reduction. However, they must be certified for lead removal.
Top Products:
- Brita Longlast Filter: Certified to remove 99% of lead.
- ZeroWater Pitcher: Features ion exchange and removes lead effectively.
- APEC Reverse Osmosis System: NSF-certified for lead removal.
2. Flush Your Water Lines
If lead is coming from your plumbing pipes or fixtures, you can reduce lead levels by flushing the lines before using water for drinking or cooking. This removes the stagnant water sitting in lead pipes.
How to Flush Your Water:
- Run the tap for 30 seconds to 2 minutes before using water for drinking or cooking, especially if the water has been sitting in the pipes for several hours (e.g., overnight or during the day).
- Always use cold water for drinking and cooking, as hot water can dissolve lead more easily.
Pros:
- No cost or special equipment needed.
- Easy to implement in everyday routines.
Cons:
- Only reduces lead temporarily; it doesn’t remove it completely.
- Wastes water unless you use the flushed water for cleaning or other non-consumptive uses.
3. Use a Lead-Reducing Shower Filter
While drinking water is the primary concern, lead can also be absorbed through the skin in the shower, especially when using hot water. Installing a shower filter certified for lead removal can minimize lead exposure while bathing.
How it Works:
- Activated carbon filters in shower heads can reduce lead and other contaminants like chlorine.
Pros:
- Reduces lead exposure in hot water during showers.
- Easy to install without the need for professional help.
Cons:
- Doesn’t address lead in drinking water.
4. Use Only Cold Water for Drinking and Cooking
Lead dissolves more easily in hot water, so avoid using hot tap water for consumption or cooking. Always boil cold water if you need hot water for cooking, even for tasks like making coffee or tea.
Pros:
- Simple and free to implement.
- Reduces the risk of lead leaching into your water.
Cons:
- Doesn’t remove lead, only minimizes risk.
5. Collect Rainwater (Safely)
Collecting and purifying rainwater can provide a lead-free alternative if your local water supply has contamination issues. However, rainwater needs to be filtered and stored correctly to prevent contamination from air pollutants or dirt.
Steps:
- Use a rain barrel or cistern to collect rainwater from your roof.
- Install a filtration system to remove dirt, dust, and bacteria before use.
- Boil or filter the water with a lead-removing filter before drinking.
Pros:
- Rainwater itself is typically lead-free.
- Natural and renewable water source.
Cons:
- Requires proper filtration and safety measures.
- Not feasible in all climates or urban areas.
6. Install Lead-Free Plumbing Fixtures
In many older homes, lead contamination comes from lead pipes, faucets, or fixtures. By replacing these components with lead-free plumbing materials, you can naturally reduce lead exposure.
Steps:
- Replace old lead pipes with copper or PEX pipes (consult a plumber if necessary).
- Install lead-free faucets and fixtures, which are now required in new plumbing installations.
- Consider whole-house repiping if lead contamination is severe.
Pros:
- Long-term solution to eliminate the source of lead.
- Reduces lead exposure throughout the home.
Cons:
- High cost and labor-intensive, especially for whole-house repiping.
- Requires professional help unless you are experienced in plumbing.
7. Boiling Water (Not Effective for Lead)
It’s important to note that boiling water does not remove lead. In fact, it may increase the concentration of lead in the water, as the water evaporates and leaves the lead behind. Always use other filtration methods rather than boiling to remove lead from your water.
Conclusion:
To naturally reduce lead from drinking water, combining methods like using a certified lead filter, flushing water lines, and avoiding hot tap water for consumption will significantly lower lead exposure. The most effective “natural” solution comes from activated carbon filters (like those found in Brita Longlast or ZeroWater filters), while installing lead-free plumbing fixtures can provide a more permanent solution. While rainwater collection offers a lead-free source of water, it’s essential to properly filter it to ensure safety.
