Getting Lead Out of Water, What is now referred to as the “Flint Water Crisis” occurred in 2014 and made the nation aware of the risks posed by lead-contaminated water. Thousands of people in Flint, Michigan, were exposed to lead through their tap water after the city changed its municipal water source.
The Flint Water Crisis demonstrated that lead exposure risk still exists even though lead is not used in new plumbing fixtures. Many outdated lead-containing pipes are still in use today across the nation, as was the case in Flint.
Because lead is toxic to both children and adults, it’s critical to understand the dangers and discover ways to protect your home’s water supply from this unsettling contaminant.
The risks associated with lead, how to check if lead is present in your drinking water, and how to remove lead from water using reverse osmosis, water distillation, and activated carbon filtration when set up for lead reduction are all covered below.
How is lead introduced into water?
When lead-containing pipes and other plumbing fixtures corrode, lead can leach into the water and cause contamination. Older pipes are more susceptible to corrosion, which is more of a concern when the water is highly acidic or mineral-deficient.
While lead does not naturally exist in water, it does exist in the earth’s crust and was once a common ingredient in the manufacture of paint, gasoline, and plumbing supplies. Although lead use was drastically reduced in the 1970s and 1980s, lead is still obviously dangerous to human health today.
Older homes constructed prior to the Safe Drinking Water Act’s 1986 amendment, which forbade the use of lead-containing pipes, solder, and flux, tend to have more lead plumbing fixtures.
According to the Environmental Protection Agency, lead service lines are typically the most significant source of lead in water and are more prevalent in older cities. Therefore, even if your home’s pipes are lead-free, there is still a chance that the tap water you use contains lead.
How much lead in drinking water is safe?
Lead in drinking water is never safe in any amount. The EPA has set a limit of zero for the amount of lead that can be present in drinking water. In addition to being unhealthy at low concentrations, lead can build up in the body over time and cause high levels of health problems.
A plumbing fixture complies with the Safe Drinking Water Act if it has less than a 0.25 percent weighted average of lead across its surface. Despite the fact that this is a small quantity, it is crucial to be aware that “lead free” does not always equate to having no lead and that trace amounts of lead can contaminate drinking water.
Is lead present in drinking water harmful?
Yes, drinking water containing lead is very dangerous. Since children are more susceptible to the negative physical and behavioral effects of lead exposure than adults are, lead is particularly dangerous to children. According to the Centers for Disease Control (CDC), four million homes across the country’s population of children are exposed to high levels of lead through their water supply.
Even though adults can withstand higher levels of lead exposure, they are still susceptible to its negative effects, including kidney, reproductive, and cardiovascular issues. Due to the increased risk of miscarriage, stillbirth, premature birth, and low birth weight associated with lead exposure, pregnant women and their unborn children are at an even greater risk.
What negative effects does lead have on young people?
- damage to the nervous system and brain
- Having trouble learning
- Attention Deficit Hyperactivity Disorder (ADD)
- delayed physical and mental development
- distorted opment distor
- a higher risk of developing high blood pressure.
- kidney injury
- Reproductive difficulties
What harmful effects does lead have on fetuses that are developing and on pregnant women?
- Premature birth, stillbirth, and increased risk of miscarriage
- Preeclampsia risk is increasing.
- babies’ low birth weight
- Baby brain, kidney, and nervous system damage
How can you tell if your tap water contains lead?
By contacting your municipal water provider, testing your water with a home lead test kit, and determining whether your home has lead pipes or is served by lead pipes, you can determine whether there is lead in your tap water. Tests are the only way to confidently determine whether the water supply in your home contains this harmful contaminant because lead has no taste or odor in water.
Municipal water providers are required by law to provide you with the results of any tests they have conducted on the water supply if you ask for them. A home lead test is also advised because a municipal water test won’t show whether lead is getting into your water through your home plumbing. Additionally, it is the homeowner’s duty to test their well water for contaminants such as lead if they are using it.

How to check your water for lead:
The majority of home lead test kits are simple to use, requiring only the insertion of a test strip into a sample of your water. Unfortunately, the majority of home test kits only let you know whether your water has a positive or negative lead reading. They won’t disclose the amount of lead in your water.
The EPA advises working with a state-certified laboratory to conduct a test in order to get a precise reading of the amount of lead present in your water.
How to test for lead in your pipes:
By using a scratch test, you can determine whether your pipes contain lead. If corrosion has accumulated on a pipe, use a coin or the flat edge of a screwdriver to gently scratch through it. The pipe is probably made of lead if the scratched area appears shiny and silver.
The best course of action is to hire a water expert or a licensed plumber to professionally inspect your pipes, even though this test is a useful way to determine whether the water supply in your home is at risk of lead exposure.
How can lead be removed from water?
When set up for lead reduction, reverse osmosis, distillation, and activated carbon filtration can all remove lead from water. Finding and replacing all of your home’s lead-containing pipes and plumbing fixtures is another way to get rid of lead.
One of the following filtration systems, however, can offer a useful defense against lead and can give you peace of mind because water may pass through lead pipes before it enters your home’s plumbing system.
We advise point-of-use filters for lead reduction, even though filtration systems can be created as whole-house or point-of-use (POU) filters. If lead is coming from your home plumbing or municipal water, you can protect yourself by installing a point-of-use filter on each faucet in your house.
A whole-house filter, on the other hand, would only shield you from lead in the public water supply. You can install point-of-use filters such as reverse osmosis units, water distillers, and carbon filters to make sure that the water you drink has been lead-filtered.
One is reverse osmosis.
Pressure is used in a reverse osmosis (RO) system to force unfiltered water through a semipermeable membrane. Small pores in the membrane allow it to block contaminants like lead while still allowing clean water to pass through to the other side.

The process of distillation purifies water by simulating the way that water is naturally cleaned: by evaporation in the atmosphere. Since lead and other contaminants cannot be converted into steam like water can, they are removed by water distillers. The water is clean once it has reverted to a liquid state.

3. Filters with activated carbon
Activated carbon, which has a lot of pores on its surface and in its structure, is a component of carbon filters. Chemicals and other contaminants are removed from the water after it passes through the activated carbon, leaving only clean water behind.
It’s crucial to keep in mind that not all carbon filters can remove lead. Only those that have been certified to do so can filter lead, which necessitates using carbon that has been specially treated to reduce lead or combining it with another filtration medium that has been created and certified to remove lead. To confirm that your filter has been evaluated and certified, look for the National Sanitation Foundation (NSF) certification or the Water Quality Association certification.

How can the danger of lead in tap water be lessened?
By only using cold water and letting your water run for a few minutes before using it, you can lessen the chance that your tap water contains lead. In comparison to cold water, hot water corrodes lead and makes it easier for lead to dissolve in water.
It is safer to get cold water from the faucet and then heat it yourself if you need hot water for drinking or cooking. Contrary to popular belief, lead cannot be removed from water by boiling it. Additionally, the chance that lead will leach into the water increases the longer the water is left in lead pipes.
If the water has been sitting in the pipes for longer than six hours, the CDC advises running it for two minutes before using it.
Can you take a shower in water that contains lead?
Showering in lead-contaminated water is safe, yes. It should be safe for both children and adults to take a bath in lead-contaminated water because human skin does not absorb lead from water. However, if the water gets into your mouth while you’re taking a shower or bath, you could ingest very small amounts of lead.
