How to Remove Lead from Drinking Water


How to Remove Lead from Drinking WaterLead contamination is a growing concern throughout the nation and how lead can be removed from drinking water is a question we’re often asked.

Since the incident in Flint, Michigan brought the national spotlight on lead, a number of other cities have since found excessive levels of lead contamination in their water supplies.

USA Today reports they have, “Identified almost 2,000 additional water systems spanning all 50 states where testing has shown excessive levels of lead contamination over the past four years. The water systems, which reported lead levels exceeding Environmental Protection Agency standards, collectively supply water to 6 million people.”

Why is Lead Dangerous?

Lead exposure can pose a serious health threat. In fact, lead contamination has been linked to the following issues in children:

  • Behavior problems
  • Impair brain development
  • Heighten attention disorders
  • Reduce IQ
  • Delay physical development

Why is Lead in Our Drinking Water?

Lead is a natural element found in the earth’s crust and thus can be found in our water, air,

Lead can come from the source water of municipal suppliers

and soil.  And before the dangers of lead were understood, lead was commonly used in paint, pipes batteries, ceramics and even cosmetics. Thus, the potential exposure to lead is all around us.

When we’re talking about water being contaminated with excessive lead levels, this is generally from lead in the soil or from lead pipes. Even though pipes are generally made of copper rather than lead today, many of the pipes that carry water to our homes are still lead because the infrastructure is in place and removing it would be costly and time consuming.

How to Protect Your Household from the Dangers of Lead

Lead contamination can pose a serious health risk when ingested or inhaled. It is especially dangerous for children, seniors and pregnant women. There are a few specific ways to reduce the risk of lead contamination.

Water Sitting in Pipes.

When you’re away from home for several hours, it’s a good idea to flush the water when you return. The longer water sits in pipes, the more lead it may contain. So run the tap for a couple of minutes, flush the toilet or take a shower (skin does not absorb lead in water so you’re OK to shower).

Hot vs. Cold Water.

For drinking water, it’s best to get water from the “cold” side of your tap. Because water temps play a role in how corrosive water can be, pull from the cold faucet and then heat up the water for that baby bottle or cup of cocoa.

Install a Reverse Osmosis Water Filtration System

For a long-term solution that will ensure your household is protected from the dangers of lead contamination 24/7, installing a reverse osmosis water filtration is a possibly the best method. Reverse osmosis is widely considered to be the most thorough and cost-effective way to remove lead from drinking water since an RO system can effectively remove up to 98% of lead from water.

How Does Reverse Osmosis Remove Lead

Reverse osmosis uses household water pressure to push water through a series of filters. The RO membrane can filter out impurities such as lead, arsenic, nickel, nitrates and dozens of other contaminants. These impurities that are trapped by the fine RO membranes are flushed away, leaving delicious, clean drinking water.

  • I didn’t realize that lead exposure could lead to such serious problems. I like your tips to flush the water from your pipes if you have been away from home for a while and to install a filtration system. What happens to the lead that is removed by these kinds of filters? I like that they get rid of more than just lead so you get really clean water. Thanks for sharing this information!

      Hi April: all contaminants that are captured by the RO membrane are subsequently flushed away –so that you’re left with clean, delicious drinking water.
