How To Filter Lead Out Of Drinking Water?

How to Remove Lead from Water?

The lead in drinking water issue in Flint, Michigan, thrust lead to the forefront of public discourse. The findings of a USA Today investigation confirmed that Flint was not an isolated incident. It was discovered that approximately 2,000 water systems, spanning all 50 states, were supplying water that contained high amounts of lead to 6 million people, according to the research.

How Does Lead Get Into Drinking Water?

The presence of lead in our drinking water may be traced back to the corrosion of the pipes that transport water to our homes, schools, and daycare facilities.Fixtures and pipelines are particularly vulnerable to corrosion when the water is acidic or has a low mineral content.Although most pipes nowadays are constructed of copper, the potential of lead contamination in drinking water is substantial since many homes built before 1986 still have lead solder connecting their copper pipes.According to the Centers for Disease Control and Prevention, children in 4 million US families are exposed to high amounts of lead in their drinking water on a daily basis.Despite the fact that the pipes transporting water are spanking new, it is possible that the water is contaminated with lead.

  • According to the Environmental Protection Agency, hundreds of large cities in the United States still use 100 percent lead pipe to link municipal water facilities to homes and businesses.

How to Remove Lead in Water

The Centers for Disease Control and Prevention recommends two methods for removing lead from drinking water: reverse osmosis and distillation.

  1. Reverse osmosis is a simple and cost-effective method of protecting your family drinking water by removing pollutants such as lead from the water. In order to remove 99.1 percent of lead from water, reverse osmosis is used
  2. distillation, on the other hand, is a very slow process that takes a lot of energy from a heat source, making it less than ideal.

During the reverse osmosis water treatment process, the water is forced through a series of filters by the pressure of the domestic water supply.The reverse osmosis membrane in a water treatment system will filter out impurities, including lead, and will remove it from the water.Water that has undergone reverse osmosis (RO) filtering is free of contaminants, leaving you with purified, safe drinking water.Aside from being a very successful purification process, reverse osmosis has a cheap production cost (just pennies per gallon), requires no energy, and is simple to clean and keep in working order.In order to understand more about the operation of reverse osmosis, see Understanding Reverse Osmosis.

Does Boiling Water Remove Lead?

Boiling your water will not eliminate lead from it; in fact, boiling your water may increase the quantity of lead in it.As water evaporates throughout the boiling process, the lead-to-water ratio becomes larger than it was when the process began.To properly remove lead from water, the Centers for Disease Control and Prevention website recommends ″water treatment procedures such as reverse osmosis, distillation, and carbon filters that are specifically intended to remove lead from water.″

How to Reduce Lead Risk in Drinking Water

1) How long water has been sitting in pipes: If a faucet has been left open for more than six hours, the Centers for Disease Control and Prevention recommends that you run water for 1-2 minutes.The longer water has been lying in pipes, the greater the likelihood of lead contamination in the water.Flushing your pipes may be wasteful, so you may want to try taking a shower instead of flushing your pipes to save water.(You might wonder, ″Is it safe to take a shower with lead water?″ Showering or cleaning while flushing the pipes is safe since human skin does not absorb lead from water.2) Water Temperature: Hot water dissolves and corrodes lead more readily than cold water, thus when taking water from the tap for drinking or cooking, get it from the ″COLD″ side of the faucet and heat the water yourself to lessen the likelihood of lead contamination.

  • ″Do not prepare cereals, beverages, or infant formula using hot tap water.″ It is possible to take cold water after cleansing the faucet and then heat it if necessary″ (Centers for Disease Control and Prevention).

Can Lead in Water Make You Sick?

  • According to the Environmental Protection Agency, lead is a major health hazard, particularly for pregnant women, babies, and young children. Lead exposure, for example, has been related to the following problems in children: Physical development delays
  • behavioral difficulties
  • harm to developing brains

Aside from children, adults are also at danger when it comes to the health implications of lead in water. According to the data, lead exposure is associated with renal issues, high blood pressure, and an increased risk of cardiovascular mortality.

How do I Know if There’s Lead in My Water?

1.Purchase a test kit: Because lead cannot be tasted, seen, or smelled in water, the only method to determine whether or not it is present in your water is to do a water test.For between $10 and $20, you may get simple tests from your local home improvement store.If you want a more in-depth water analysis, your local or state drinking water authority can supply you with a list of approved laboratories for your convenience.The EPA requires that all community water providers compile and distribute an annual water quality report to its consumers by July 1 of each year, as mandated by the Environmental Protection Agency (EPA).

  • You may locate your local Consumer Confidence Report on the EPA’s Consumer Confidence Report website.
  • This Contaminant Rejection Table contains more information on the impurities that can be eliminated by a reverse osmosis system (including the percentage of contaminants removed).

How to Filter Lead from Your Tap Water

The majority of the twentieth century saw American communities and homes put lead pipes and solder in their water distribution systems, leaving a hazardous legacy for future generations.And it’s not expected that the situation will improve very soon.Anyone, no matter where they reside, may utilize easy ways to determine whether or not their tap water has lead contamination.In the United States, the Environmental Protection Agency requires that most water utilities test their drinking water and take steps to prevent lead pollution if the lead level in the water reaches 15 parts per billion (ppb) in more than 10% of the residences that they sample.During extreme incidents of lead pollution, such as the one that occurred in Flint, Michigan, municipal utilities must educate citizens on how to avoid drinking lead-tainted water while the utility attempts to determine the source of the contamination.

  • When the situation is less severe, water companies are gradually replacing outdated lead-based water lines and pushing people to remove lead pipes and fixtures from their houses.
  • However, this is a slowed-down and more expensive procedure.
  • It is possible that replacing water pipes will cause lead levels to surge for a period of time after the new lines are placed.
  • In the meanwhile, we may filter our water to decrease the amount of lead that our families are exposed to.
  1. Water filters that are particularly intended to remove lead from drinking water are available that are both effective and inexpensive.
  2. Most carbon-based faucet-mount filters are effective in their respective fields of use.
  3. Some are available for as low as $70 a year.

Many pitcher filters are not approved to remove lead, and as a result, they do not perform as well in this application.For help finding a water filter that meets your needs and fits your budget, see the Environmental Working Group’s Water Filter Buying Guide.Look for models that are certified for lead removal by NSF International, the California Environmental Protection Agency, or the Water Quality Association.

  • Look for a product that eliminates more than 99 percent of the lead present in tap water before purchasing it.
  • Before making a purchase, double-check the model number because product characteristics are subject to change.
  • Use filtered water for both drinking and cooking to keep your family’s exposure to lead to a bare minimum.
  • Filters should be changed on a regular basis to ensure that the gadget continues to perform effectively.
  • The lead content of cold tap water is often lower than that of warm or hot tap water.

Lead cannot be removed from water by boiling it.If you have children under the age of six at home, or if you or someone else in your family is pregnant, nursing, or wanting to become pregnant, take particular precautions to ensure that lead is removed from your tap water.Infant formula should be mixed with filtered or bottled water.Lead has been shown to cause damage to virtually every organ system in the human body, with the brain being the most severely affected.Numerous health concerns, including lifelong brain damage and diminished intelligence, as well as miscarriage and early delivery, have been linked to it.According to some research, lead exposure throughout childhood is associated with an increase in criminal conduct.

The age at which children grow less sensitive to lead is approximately seven, when their bodies become more capable of preventing lead from entering their brains.Lead exposure, on the other hand, should be avoided by everyone due to the fact that it is detrimental to people of all ages.

How To Filter Lead Out of Your Water

If you go to your faucet to fill up a sippy cup of water for your child, you don’t give a second thought to the toxins that can be present in the water.And why would you want to?There are restrictions in place by the Environmental Protection Agency to guarantee that your water does not exceed any potentially unsafe levels.You may have heard about lead in drinking water since the Flint disaster began in 2014, but there is no way that it could have an impact on your health or your family.Right?

  • Unfortunately, this isn’t the case in this instance.
  • In any case, this is not always the case.
  • As reported by the Centers for Disease Control and Prevention (CDC), at least four million homes have children who are exposed to high levels of lead, and it is projected that 63 million Americans have been exposed to lead in their tap water in only the previous ten years.
  • What is the significance of this?
  1. Lead is a neurotoxin that may be harmful to one’s health if exposed for an extended period of time.
  2. There is no acceptable amount of lead exposure for either children or adults, and our most vulnerable group – our children – is in desperate need of our assistance.
  3. Here’s how to figure out where it’s coming from and how to keep it out of your entire household.

How Lead Gets in Your Water

63 million Americans are exposed to lead, which may be found in lead-based paint as well as your drinking water source, which is unexpected.The United States government has signed a few measures to aid in the improvement of water quality around the country, but it is still difficult to determine where the major source of lead contamination is.What we do know is that it frequently originates from underneath the surface.Even if the water comes from a source that is free of lead, it may become polluted on its trip to your tap.Even if the water comes from a source that is free of lead, it may become polluted on its trip to your tap.

  • Consider the fact that, despite the fact that the use of lead-based plumbing was outlawed in 1986, there are still many homes that have lead-based pipe that has not been updated.
  • Even if your plumbing system is lead-free, it is possible that your water will take up lead while traveling through municipal pipes on its route to your home.
  • So, what are you supposed to do in the meantime?
  • It is only by using a water filter that you can significantly lower the amount of lead in your drinking water.
  1. Not all water filters, on the other hand, are created equal.
  2. A water filter is an investment, and you want to make certain that you are getting the most value for money possible.

Understanding Your Contaminants

In order to choose which filter is the most appropriate for your needs, you must first determine what is flowing out of your faucet.Besides lead, there are several other contaminants that might be present in your drinking water.Heavy metals such as mercury and environmental pollutants such as medicines, herbicides, and pesticides can be found in treated drinking water, as well as other contaminants.In addition, the disinfectants used to clean your drinking water are frequently harsh compounds such as chlorine or chloramines, which can cause skin irritation.It’s possible to find out what’s poisoning your water by looking online for a Water Quality Report for your region or by calling your municipal authority.

  • Locate a filter that will eliminate the impurities that can have a bad impact on your health or the flavor of the water you are drinking.

Look for the Certification

For starters, be certain that your filter has been approved by a third-party organization such as the NSF or the IAPMO. Groups like these provide third-party, independent testing and certification, so you can be certain that the filter you’re purchasing has been thoroughly tested and shown to deliver real-world outcomes.

Getting Lead Out

Reverse osmosis and ion-exchange are two methods for removing lead from water that are both successful.When exposed to pressure, reverse osmosis is the process by which a solvent passes through a porous membrane in the direction opposite to that of natural osmosis.Traditional reverse osmosis systems remove practically everything from water that is bigger than a water molecule, including trace minerals that occur naturally in the water.It is necessary to remove particles such as lead, fluoride, arsenic, cadmium, mercury, and asbestos as part of this procedure.The Aquasana Reverse Osmosis System, which is NSF-certified, has two extra processes that help to enhance the RO process.

  • Aquasana Claryum® technology is incorporated to remove an additional 60 pollutants, including chlorine and chloramines (a disinfectant that contains both chlorine and ammonia), medicines, herbicides, and pesticides, among other things.
  • Once the procedure is complete, the re-mineralizer replenishes your water with beneficial minerals like as calcium, which improves the flavor of your water.
  • As the name implies, this device may be installed at the ″point of use,″ which is the sink where you desire to filter water for drinking or culinary purposes.
  • It is the exchange of ions with the same charge between an insoluble solid and a solution that is known as ion exchange.
  1. According to water filter terminology, this implies that we employ a potassium ion to form bonds with heavy metal pollutants such as lead in your drinking water and remove them from it.
  2. From the point at which water enters your home, our new OptimH2O® Whole House water filter filters it using an ion exchange process and sub-micron filtration to safeguard you and your family when you are at the sink, showering, cooking, using the dishwasher, and other household appliances.
  3. According to IAMPO, the first-of-its-kind system is capable of reducing more than 99 percent of lead and cysts and 98 percent of PFOA/PFAS, as well as chlorine, chloramines, and other contaminants.

As a company, Aquasana believes that having access to high-quality, independently verified water is something that everyone should strive to achieve.Make yourself your own best advocate by investing in a water filter that is up to the duty of producing clean, healthful water every time you turn on the water faucet.Protect Your Family and Your Home From Lead

Top 6 Water Filters To Remove Lead From Water

Lead is plentiful in our water and is considered to be one of the most serious environmental and health risks.Following the recent Flint water crisis, numerous questions were raised about the quantity of lead present in drinking water based on where individuals reside in the country.Several pollutants are present in our drinking water, and these toxins represent a major threat to human health.Lead is a neurotoxin that was widely employed in the construction of pipes many years ago and is still in use today.Due to the fact that the pipeline system had not been updated for many years, the deterioration of pipe materials resulted in the leakage of large levels of lead into the drinking water supply.

What does lead do to our health?

  • Lead is a neurotoxin that may induce mental issues as well as severe kidney damage if consumed in large quantities. Lead also has the additional effect of damaging red blood cells as well as the walls of the blood stream. It is extremely harmful for pregnant women since it poses a serious threat to the lives of unborn children as well as infants. The effects of this drug can be severe even in young children as young as 7 years of age, resulting in many abnormalities and disabilities such as: retardation of mental and physical development
  • reduced IQ
  • attention disorder, problems with general behavior
  • damage to the nervous system
  • and permanent brain and nerve damage.

How can you remove lead from water?

Fortunately, lead can be removed from our drinking water with a simple chemical process.One of the most straightforward methods of removing lead from water is to use the appropriate water filter after establishing the source of contamination and the intensity of lead buildup per gallon.It is critical to determine the source of the lead contamination in the water supply system.The majority of water distribution pipes in the United States are composed of copper, and their fixtures are linked using corroding solders, which leak large amounts of lead into the environment.This issue is more prevalent in places where dwellings and drainage systems were constructed prior to 1986, in particular.

  • In other words, if you are relying on the city’s drinking water supply, there is nothing you can do to clean the water source other than replacing the water source itself.
  • However, if the water comes from a private source such as a borehole or a well, you can investigate possibilities for removing lead from the water at the source.
  • The issue here is the amount of time water sits in the pipelines before being released.
  • The longer the water remains in those pipelines, the greater the likelihood that it may collect lead.
  1. It is always possible, if eliminating the source of lead buildup appears to be too expensive, to employ the least expensive technique of cleaning the water that comes into the house itself by using the appropriate water filters for the situation and requirements.

The right filtration methods to remove lead from water

It is simple to install a water filter for the removal of lead, but it is much more difficult to select the most appropriate filter for your needs. However, there are three fundamental water filtering processes that may be used to remove lead from water:

1. Reverse Osmosis

Reverse osmosis (RO) is the most extensively used and least expensive way of lowering the level of lead in water and removing it.Complete Reverse Osmosis is not commercially accessible due to the high cost of the technology and the fact that it is only employed by high-end water filtering equipment.However, partial reverse osmosis, which is sold by the majority of water filter firms, is inexpensive and removes 95 percent of the lead from water.Related Article: The Advantages of Using a Reverse Osmosis Filter System

2. Activated Carbon Filtration

Activated carbon is capable of absorbing heavy metals such as lead and magnesium, as well as a wide range of other hazardous pollutants.However, not every carbon activated filtering system is effective at removing lead completely.Consequently, the filter cartridges become overfilled and must be replaced on a regular basis.The effectiveness of the filters to remove lead from water diminishes after a certain volume of water has been processed, and this is dependent on the quality and power capability of the filters used.

3. Distillation

Distillation produces water that is nearly clean.The downside is that it is one of the most costly techniques of removing lead from water, and it becomes less expensive as the volume of water filtered in a single pass grows.In addition, the technology is highly good in removing lead from water, even after extended periods of use, and it needs less replacement of filtration cartridges than other methods.Distillation requires a significant amount of power to operate and takes a significant amount of time to complete.

Top 6 water filters to remove lead from water

There are several different types of water filters available that are effective at removing lead from water.However, picking the most appropriate one for your needs will provide you with the greatest value for your money.However, before purchasing any of the types of water filters listed below, it is necessary to double-check a few things.For any water filter that you purchase, search for the NSF (National Sanitation Foundation) certification.This is because the requirements necessary to get the NSF certifications are fairly high in terms of both quality and energy efficiency.

  • Standard 53 of the National Sanitation Foundation is required for water filters.

1. Reverse Osmosis Filters

RO systems are capable of removing 94 percent to 97 percent of the lead from water, depending on the model.However, due to the fact that the systems available for personal or commercial use are not full reverse osmosis systems, some quantity of contaminants remains in the water after filtering.It is recommended that an activated carbon filter cartridge be added to the RO system in order to obtain entirely clean water that is free of lead.

2. Filter Pitchers

Activated carbon derived from coconut, combined with ion exchange resin, is used in regular filter pitchers to significantly lower the levels of lead in water by a wide margin.Because of their low cost and energy-efficient operation, they are easily transportable and useful for personal usage.In addition to the WQA certification, which demonstrates that filter pitchers remove up to 99 percent of lead from water, filter pitchers require an extra certification of standards.

3. Faucet Mount Units

The market is flooded with several types of water filtration systems that may be put directly over the sinks’ faucets.The removal of lead, mercury, microbial cysts, chlorine, disinfection byproducts, and a variety of medications is possible with these devices.In order to function, these machines do not require power to run and instead rely on the pressure per gallon of water that is delivered to the faucet.If the PPG of your water supply is not greater than 50 scales, you may need to install a water pump over the water main line in order to achieve the optimum results.The filter cartridges must be replaced on a regular basis, however they are rather inexpensive.

4. Whole House Filters

In order to prevent water from entering the house, point of entry water filters or whole house water filters are installed on the mainline before the water is turned on.Whole-house water filters are extremely successful in purifying well water and reducing the levels of iron and lead in it to a significant degree.The 15ppb and 25ppb filter categories are among the most suited for big water systems with daily consumption rates exceeding 100 gallons.100ppb water filters are suited for commercial use or for use on a large scale of up to 1, 50,000 gallons per day, depending on the application.

5. Shower head filters

Lead has been shown to damage hair.Even in adults, direct contact with lead on the scalp can allow water to permeate straight into the skull, resulting in serious brain problems and other complications.Shower filters employ a particular medium to filter out up to 99 percent of the lead from the water they circulate through.The elevated level of lead in the hot water that comes from the water warmers is also removed by these devices.

6. Undercounter purifiers

Undercounter water filters are one of the most often utilized types of drinking water purifiers.There is no RO process involved; instead, they use a separate filtration method that can remove up to 99.9 percent of lead from drinking water.Under sink filters are also available with temperature control, which helps to prevent lead from accumulating in the containers.Due to the fact that they are inline filters, installation is simple and inexpensive.

How to Make Sure Your Water Filter Really Removes Lead

The mayor of Newark distributed water filters to households last year as a result of an issue with excessive levels of lead in the city’s drinking water.It was just this week that the Environmental Protection Agency notified the city that drinking water samples from two of three residences it examined still contained high levels of lead, despite the filters being used to treat it.The Environmental Protection Agency (EPA) warned Newark citizens to refrain from drinking tap water and encouraged the city to provide bottled water instead (though that solution also ran into problems when the city learned some of the water had passed its expiration date).It’s unclear why the filters in the two houses — which have been verified by globally recognized laboratories and were effectively utilized during the Flint, Michigan, water crisis — didn’t remove the lead at the levels predicted in these tests.NSF International, one of the groups that sets the industry standards for water filter certification, says, ″This is a little shocking to us.″ Rick Andrew, director of development at NSF International, describes the situation as ″quite startling.″ ″This is something we’ve never seen before, and it’s clearly an uncommon circumstance,″ says the team.

  • Filters that are certified to eliminate lead must pass stringent testing by the National Sanitation Foundation (NSF) or other laboratories.
  • The Water Quality Association, for example, tests the filters with water that has been polluted at 150 parts per billion (ppb), which is ten times greater than the Environmental Protection Agency’s action limit of 15 ppb.
  • Even when tested with water that was polluted to 1,000 parts per billion (ppb), researchers in Flint discovered that the filters were still capable of removing all lead from the water.
  • During the course of the ongoing investigation into the apparent failure of the filters in the two Newark houses, CR consulted with water experts who explained some of the reasons why your filter may be failing to remove lead correctly.
  1. Find out how to prevent this from happening to your own water filter in the following guide: The filters that were supplied in Newark were activated carbon filters that were certified to eliminate lead from drinking water.
  2. However, not all filters are capable of doing so.
  3. So, to begin, make certain that the filter you are using is approved by the National Sanitation Foundation, the Water Quality Association, or another certifying institution.

Look for those that state that they comply with Standard 53, which is for lead.Two certified pitcher filters were included in CR’s water filter ratings of pitcher filters, and we validated that they successfully remove lead.The Flint water crisis prompted Shawn McElmurry, a Wayne State University professor who conducted significant field study during the crisis, to assert that activated carbon has a lot of surface area with nooks and crannies where pollutants might adhere.

  • ″However, it is not limitless.″ Consider the scenario of tossing tennis balls at a wall of Velcro that can hold 100 tennis balls.
  • It will get increasingly difficult to find a spot for the ball to stick the more you throw, until soon there will be no area left at all, and further balls will bounce off the wall.
  • McElmurry believes that there may be additional toxins in the water that are fighting for those attachment sites, which would further complicate matters.
  • And if some of those pollutants have more mass or energy than others, they may be able to knock some lead away, just like tossing softballs at a Velcro wall of tennis balls may knock some lead loose.
  • A water test will tell you everything about your water, including how much lead is present and what levels of lead you’re dealing with if any.

The Environmental Protection Agency suggests choosing a lab that has been certified by your state.Free water testing kits are available from several state and municipal health authorities.The cost of testing is normally between $20 and $100.Because lead filters are not tested at concentration levels more than 150 parts per billion (ppb), if your lead contamination reaches that level, or if you have a high concentration of other pollutants, you may want to consider utilizing a reverse osmosis filtering system.They are, however, expensive: some models cost $1,000 or more, in addition to annual fees for components and labor to have a professional disinfect and inspect the system.In addition, they may necessitate the installation of specialized plumbing.

In most cases, faucet-mount filters, such as the ones used in Flint and Newark, cost $20 to $40 and need multiple processes to be completed, all of which might go wrong.In McElmurry’s opinion, ″it is difficult to install these filters onto the faucets.″ ″We discovered that many people in Flint who have arthritis or impaired motor function in their hands were unable to attach them,″ says the researcher.In addition, faucet-mounted filters sometimes require specific adapters or do not fit on faucets at all, depending on the manufacturer.The filter or adapter may not fit correctly in the housing, resulting in a little amount of water bypassing it and going directly into your drinking glass.To install these filters, you must first remove the faucet’s aerator, which is a little disc screwed into the faucet tip that controls water flow.This will reveal threads beneath the faucet tip.

Most faucets with external threads may be screwed on with the filter; however, faucets with internal threads will require an adaptor.Never demand a precise fit if none of the adapters are available.Instead, contact the maker and request that others be tested.Make sure the filter is screwed on level as well, and then tighten it by hand rather than with pliers, which might cause it to shatter.″It’s so straightforward, yet a lot of people don’t do it,″ says Andrew of the National Science Foundation.However, changing the filter after it has reached its maximum capacity is the most effective approach to guarantee that lead continues to be filtered out.

The majority of faucet-mounted filter cartridges can filter around 100 gallons of water, whereas pitcher filters can filter approximately 40 gallons.In both circumstances, the filters are often equipped with electronic indicators that alert the user when it is time to replace the filter cartridge, based on either the amount of time that has passed or the amount of water that has passed through.However, they are powered by non-replaceable batteries that will eventually cease operating and will no longer be able to alert you when it is time to replace the filter.Then you’ll have to decide if you want to spend the money on a new device or keep track manually, maybe by setting a reminder on your calendar.If you use activated carbon filters for an extended period of time, they will eventually reach a point where they will not be able to hold any more lead.

If you use them for an extended period of time, lead may pass through the filter, says James Dickerson, CR’s chief scientific officer.″Heat has the potential to significantly impair the chemical-physical processes involved in activated carbon’s capacity to absorb pollutants,″ Dickerson explains.For starters, high temperatures can interfere with the bonds that allow lead and other compounds to adhere to activated carbon, causing them to become less effective.For example, they have the potential to enhance the rate at which lead flows through water, making it more difficult for filters to catch it.

It also makes it simpler for bacteria to grow on the filter, which can interfere with the filter’s capacity to remove lead from the environment.It is fine if you mistakenly turn on the hot water for a few seconds and then switch back to cold water because the filter will not be damaged.However, discard the hot filtered water and flush the filter with cold water to remove any remaining contaminants.If you have left the hot water running for an extended period of time or have used extremely hot water, change the filter immediately.It’s possible that there is a break in the carbon block or a fault in the device itself, which would allow an uninterrupted passage through or around the filter, according to McElmurry.Some filters may have manufacturing flaws that must be addressed.

Alternatively, you may cause harm to it by dropping it or exposing it to hot water, which would cause the plastic filter housing to melt.Occasionally, extra sediment in your water might build up in the system and block it, preventing appropriate sealing and water flow from occurring.As Dickerson points out, ″even a small number of particles can choke up the flow of water until it is reduced to a trickle.″ ″Water pressure is required by these water filters in order to get the water into the filter at a precise velocity, move it around in there, and get it out.″ Do you have water that doesn’t taste good?

How to Remove Lead From Water (2022 Ultimate Guide)

Lead is one of the most prevalent pollutants detected in drinking water sources in the United States, particularly in urban areas.It’s not surprising that you’re concerned about lead intake because it’s been related to cognitive and cardiovascular disorders, reproductive troubles, high blood pressure, impaired kidney function, and other health concerns.Here, I’ll go through how lead gets into water in the first place, and I’ll give you some information on the most successful techniques of eliminating lead from your water supply, which are distillation and reverse osmosis, in this tutorial.

How Can Lead Get Into the Drinking Water Supply?

Once upon a time, hundreds of thousands, possibly even millions, of lead pipes were laid beneath our feet to bring water to our houses and other structures.When these pipes were constructed, the dangers of lead exposure were still largely unknown to the public.However, it was only a few years later that studies revealed some really terrible information concerning the dangers of lead ingestion, prompting the government to outlaw lead pipes.In contrast, the Environmental Protection Agency (EPA) never insisted on the removal of old lead pipes; rather, it only insisted on the construction of new pipes from lead-free materials.This implies that thousands of water pipes carrying drinking water to houses in the United States continue to leach excessive amounts of lead into water sources.

  • Even today, man-made water pipes remain the primary source of lead contamination in drinking water.
  • Alternatively, if you live in an older home where your water pipes haven’t been replaced in decades, this might be another source of lead contamination in your drinking water supply.
  • It’s not always feasible – or inexpensive – to completely replace your home’s plumbing system, which means you’re stuck with lead-contaminated water for the same reason you’re stuck with lead-contaminated water if the water pipes in your neighborhood are composed of lead.

What Are the Lead Health Hazards?

The most serious concern with lead is that it is bio-accumulative, which means that it may accumulate in the human body over time, even if you are only absorbing little quantities of it through your water source.If you continue to drink the same tap water from the same faucet day after day, the little amounts of lead will accumulate in your cells rather than being excreted as a poison by your kidneys.Knowing this, it’s simple to understand why lead exposure from drinking water can result in some serious health consequences.Children that drink lead water have been shown to have developmental delays such as impaired hearing and learning impairments as well as harm to their neurological systems and poorly functioning blood cells.Lead in drinking water can cause learning and behavioral problems, as well as decreased IQ, delayed development, and anemia in children.

  • Adults who consume lead through their drinking water may experience impaired renal function, cardiovascular disorders, and reproductive complications.
  • Since lead has been related to premature growth and delayed fetal growth in pregnant women, it is especially important to monitor lead exposure during pregnancy.

How to Detect Lead in Water?

In most cases, detecting lead in water is rather straightforward, so you can find out fairly quickly whether or not you need to remove lead from water that enters your house.Because lead is colorless and odorless, it cannot be detected by sight or smell.Detecting lead contamination in your drinking water may be accomplished in two ways: by consulting consumer confidence reports or by employing a water test kit.

Consumer Confidence Reports

Your local authority produces yearly consumer confidence reports, also known as water quality reports, that are distributed to the public.Obtaining a consumer confidence report will provide you with all the information you want about your water source, including which natural resource your water originates from, how it is treated, and the trace amounts of toxins it contains, among other things.You may find your most recent consumer confidence report online, or you can contact your local government to acquire a copy if you don’t have one on hand already.When it comes to consumer confidence reports, the problem is that they will only tell you about the quality of your water after it has been treated.Water quality reports will not discover lead contamination in your water if it has leached into it on its travel to your home.

  • As a result, you may want to use a test kit to check the quality of the drinking water in your house.

Water Test Kit

Depending on the spectrum of pollutants they are able to detect, water test kits are readily accessible online and typically cost between $10 and $20.In most cases, a water test kit will include many test strips as well as a color chart.Holding a strip under cold water for 2 minutes is standard procedure for most applications.The color of the test strip will vary depending on the pollutants it contains, and you may compare the results to the color chart to learn more about the toxins present in your water.Choosing a water test kit that specifically tests for lead, as well as one or two other pollutants, will provide the most exact findings.

  • You may then compare your lead levels to the EPA’s requirements (anything above the limit of 15 parts per billion is considered a problem), and determine whether you need to take action to eliminate lead from your home’s water supply.

✅ How to Remove Lead from Water?

Remember that not all water filters are intended to remove lead, so do your homework (or simply continue reading!) to ensure you’re making a sound investment. I’ve included the most popular lead removal strategies in the next section.


Water distillation takes place in a distiller, which is often a small equipment that stands on a countertop and is powered by electricity to function.To use a distiller, all you have to do is fill the machine’s boiling chamber with water before turning it on.As the water boils, it will begin to evaporate, before condensing and travelling through a tube into a fresh pitcher of water.The reason that distilling water is so successful is that when it is converted to gaseous form, most impurities are unable to reach this condition and are left behind in the boiling chamber, where they may be destroyed.Boiling water does not usually cause lead to transform into a gas, and any that does change into a gaseous state would be incapable of returning to its liquid condition when the water particles are added back in.

  • As a result, a distiller system is one of the most effective water treatment options for completely eliminating lead from your water source.

Reverse Osmosis

While not as successful as distillation in terms of lead removal, reverse osmosis filtering systems are an excellent alternative.During the process of reverse osmosis, water is pushed through numerous filter stages and a reverse osmosis membrane, which contains small holes that only allow water particles to flow through them.During the reverse osmosis process, the residual impurities, including lead, are flushed down a drain in the system at a steady pace, resulting in clean water.It is very successful, and a RO system routinely eliminates more than 90 percent of total dissolved solids, with values as low as 50 parts per million in some instances (PPM).Because of its comprehensive filtration, it is good at removing lead from water, however it is slightly more expensive than other alternatives in this category.

NSF 53 Certified Filters

  • A growing number of drinking water filters now have the NSF 53 certification, which ensures that lead is removed from the water. A variety of water treatment filtration system types, from carbon pitcher filters to countertop systems and whole-home filters, are available with NSF 53-certified filters. Standard 53 certification by the National Sanitation Foundation indicates that a product has undergone third-party testing to ensure that its lead-filtering capabilities are as effective as stated. Filter types for which NSF currently gives certifications include: gravity pitchers/carafes
  • faucet-mounted filters
  • countertop filter units attached to a faucet
  • under-sink water filters
  • refrigerator filters
  • and other similar products.

Lead removal certification from the National Sanitation Foundation (NSF 53) is becoming increasingly common with drinking water filters.A variety of water treatment filtration systems, from carbon pitcher filters to countertop systems and whole-home filters, are available with NSF 53-certified filters installed.Standard 53 certification by the National Sanitation Foundation indicates that a product has undergone independent testing to ensure that it has the lead-filtering capabilities that are stated.Water filters such as gravity pitchers and carafes, faucet-mounted filters, countertop filter units that are linked to a faucet, under-sink water filters, and refrigerator water filters are now among the filter types for which NSF grants certification.

⚠️ Does Boiling Water Remove Lead?

Because distillation, which involves boiling, is capable of removing a significant quantity of lead from drinking water, it would seem reasonable to think that boiling water might likewise remove at least a small amount of lead from drinking water.In reality, however, this is not the case.What happens when you boil water is that some of the water evaporates, resulting in a greater concentration of lead in a given volume of hot water — that’s all it does.Water exits the boiling chamber as gas and condenses into a clean pitcher, which is the difference that allows distillation to be effective in eliminating lead and other heavy metals.When you boil water, however, it will just rise to the surface of the water as a gas, and you will not be able to collect it in its distilled state.

  • You may, however, filter out lead by creating your own distillation process at home.
  • Simply fill a pot one-third of the way with cold water and nestle a little pot within it to start the process.
  • Using an upside-down lid, set the pot on a high heat and cook for about 15 minutes.
  • When the water evaporates, it will float to the top of the pan lid and into the consense, where it will run down to the centre of the lid and drop into the little pot, leaving the lead in the large pot behind.

❔ Frequently Asked Questions

Can I remove lead from hot water?

Due to the fact that hot tap water can damage the pores of most water filter cartridges, most of them can only be used to filter cold water. This means that if you want hot water that has been filtered, you’ll have to filter cold water first and then heat it on the stove.

How do I know if my home has lead pipes?

Homes constructed before to 1986 are more likely to have lead plumbing, so if you can pinpoint the year in which your home was constructed, you’ll have an easier time determining its age.Check your pipes by feeling them – lead pipes are soft and drab grey in color, and when you scratch them with a coin, they will expose a brilliant silver metal layer beneath the surface.Even if your actual pipes and faucets aren’t composed of lead, it’s possible that you have lead solder between them, so be sure to check for that as well.

Can I get my water tested for lead?

Yes, if you want the most detailed findings possible, you should get your water analyzed by a laboratory. You may want to do this in particular if you have a well water source that contains lead and you want to be sure that your lead exposure isn’t excessively high.

What else can a water filter system remove?

Often, a single filtration system can provide many advantages, since high-quality water filters are capable of removing a wide range of toxins including lead, chlorine, pesticides, herbicides, and other heavy metals.

What type of lead water filter system is best for me?

It is dependent on your financial situation and personal preferences.Under-sink filters and reverse osmosis filtering systems are more comprehensive, but they require a pretty constant water pressure to be installed in your house, and they are also more expensive to purchase and operate both in terms of purchase and operation.It is simpler to install and utilize a faucet water filter system, filter pitcher, or distiller, which can frequently filter more than 100 gallons of water each day – just be sure that the filter you choose is capable of removing lead contamination before you make your purchase.

How to remove lead from tap water?

Are you interested in learning how to remove lead from tap water? Do you want to discover which lead water filters are the best? Where does lead originate from, why is it a health hazard, how can it be detected and removed from drinking water are all discussed in this article.

Who is at risk of lead in tap water?

According to the Environmental Protection Agency and the World Health Organization*, more than 15 percent of families in North America and 5 percent of households in Europe have lead exposure levels that exceed guideline limits.Although lead pipes and jointures in older buildings are the most common source of lead contamination, it can also flow via the municipal water distribution system, as in the case of Flint, Michigan.Due to the fact that lead exposure must be evaluated on a case-by-case basis at each faucet, we don’t know where the problem lies.What we do know is that modern buildings constructed during the 1990s have a very minimal risk of lead exposure unless there is a problem with the city’s water supply in general.For example, if you reside in a property constructed before the 1970s, Thames Water in the United Kingdom suggests using a water filter.

What is the risk?

The most serious issue is that there is no safe amount of lead exposure.Young children, who are still developing, are particularly vulnerable to the effects of exposure.As a result, even lead levels below those recommended by the Environmental Protection Agency and the World Health Organization may have a deleterious impact on health.What makes matters worse is that it is extremely difficult to test for lead in municipal drinking water.Even if a lab test does not reveal any lead in the water, it is possible that lead will be detected the next day.

  • Lead often does not leach from pipes on a continuous basis, but rather comes and goes.
  • As a result, it is preferable to be safe than sorry when it comes to towns and buildings that may be susceptible to lead corrosion and to install a water filter.

How to remove lead from tap water?

The traditional method of eliminating lead was through the use of costly reverse osmosis or distillation filters.These filters also remove beneficial minerals from the water, resulting in significant water and energy waste.One other preventive measure is to flush out lead by running the water for 2 minutes after each use of the product.The downside is that it is cumbersome, wastes water, and is still not completely safe.Thanks to recent advancements in water filtration technology and materials, this has luckily been rectified.

  • Even modest activated carbon filters may now remove up to 95 percent of lead or more, lowering lead exposure to acceptable levels in the environment.
  • These filters are simple to put on the faucet and do not require the services of a plumber.
  • They can be purchased for as low as 60 euros or pounds each year.
  • You will, however, need to select a lead water filter.

Lead in drinking water

  • Lead is a metal that may be found in the environment in its natural state. It can be found in a variety of environments, including the air, soil, food, water, and some consumer items (for example, vehicle brakes and batteries).

The amount of lead present in the environment has declined dramatically during the last several decades.Neither natural water sources nor water from drinking water treatment facilities often have high levels of lead in the United States and Canada.When lead is liberated from portions of distribution or plumbing systems, it can make its way into the drinking water supply.In older homes and neighborhoods, lead is more likely to be present in the drinking water since the National Plumbing Code of Canada regarded lead an acceptable material for use in pipes that brought water into residences until 1975.

Lead from plumbing parts

  • According to current estimates, the most major source of lead in drinking water is anticipated to be lead service lines. The water pipes that connect the residence to the main water supply are referred to as distribution pipes. Solder, faucets, and valves, as well as other plumbing parts and fittings, such as solder, may contain lead, which can leach (seep) into drinking water sources. A variety of factors can influence the quantity of lead that seeps into drinking water, including the chemistry of the water, the age of the plumbing system, and the length of time the water is allowed to remain in the pipes.
  • In order to determine whether lead service lines exist in your region, you can consult with your plumber, water utility provider, or local government.
  • Alternatively, you can inspect the water supply pipe that enters your home (you may be able to see a portion of the service line in the basement, by the water meter). The following characteristics indicate that it may be composed of lead, or that it may include lead: greyish-black color
  • soft or readily dented when scraped with a knife
  • If you have reason to believe that your service line contains lead, you can get your water tested for lead contamination. To do so, you can do one of the following things: Find out whether your municipality has a water sample program or will test your water if you ask
  • In order to obtain guidance and support with the tests, contact your local public health authority.

Health effects of lead in drinking water

  • Drinking water that contains lead, even for a short period of time, can be hazardous to one’s health. Because of the development of their brains, fetuses, babies, and children are the most vulnerable.
  • Children’s and adults’ neurological development and behavior can be affected by lead exposure, which can result in a lower intelligence quotient (IQ) in children and higher blood pressure or renal issues in adults
  • exposure to lead in drinking water can cause:

Guideline value for lead in drinking water in Canada

As a result of collaboration with provinces, territories, and other federal departments, Health Canada was able to lower its new guideline value for lead in drinking water to 0.005 milligrams per litre (mg/L), despite the fact that every effort should be made to keep lead levels in drinking water as low as possible.Canada’s health, particularly that of the most vulnerable members of society, such as newborns and children, is protected by the guideline value set by the World Health Organization.Health Canada amended the previous recommendation value for lead (0.01 mg/L) because recent scientific research have revealed that health impacts can arise from exposure to lead at far lower levels than previously anticipated, resulting in the revision of the prior guideline value.According to the Guidelines for Canadian Drinking Water Quality for Lead, the fundamental requirements that every water authority should seek to meet in order to offer the cleanest, safest, and most dependable drinking water possible are outlined.

How to reduce your exposure to lead in drinking water

  • Next confirmation that lead is present in your drinking water, there are efficient methods for removing it permanently, which are explained in the following section. Meanwhile, you may limit your lead exposure by implementing a few basic, temporary precautions such as the following: Drinking, cooking, and making infant formula should all be done with cold tap water.
  • The discharge of lead and other metals from your plumbing is accelerated by the use of hot water. Flush out your plumbing after water has been sitting in the pipes for a few hours, such as first thing in the morning or when you return home from work, and then let it run for around 1 minute to remove any remaining sediment. By flushing the toilet, having a shower, or starting a load of laundry, you can get the pipes clear.

While showering or bathing, lead will not enter the body through the skin or by inhaling vapours from the shower or bath. It is deemed safe to bathe and shower in water that has levels of lead that exceed the recommended limit for lead.

If you are pregnant or breastfeeding

  • Lead can be transferred from a pregnant woman to her fetus
  • from a mother’s breast milk to a newborn
  • and from a pregnant mother to her partner.
  • If you are pregnant or nursing and have reason to believe that your drinking water contains lead, you should have it tested immediately. If lead levels are higher than the recommended threshold, you should: seek an alternative source of drinking water
  • install a treatment device to eliminate lead
  • and seek medical attention.

If you have any questions or concerns regarding your drinking water or your health, you should speak with your local public drinking water authority or public health authority for further information about your options.

Removing lead from drinking water

For eliminating lead from drinking water, there are numerous alternatives available, including water treatment equipment, replacing lead service lines, and updating your plumbing materials.

Using water treatment devices

  • There are excellent household water treatment systems on the market that are approved to eliminate lead from drinking water right from your faucet. Carbon-based filters, reverse osmosis or distillation treatment devices are examples of such equipment.
  • For the greatest results, a device should be put at the water faucet that is most frequently used to draw drinking water. In the majority of situations, this is the kitchen faucet. Make certain that any device you purchase is: certified as meeting the NSF International standard for lead removal (look for this certification on the box or label)
  • installed and maintained in accordance with the manufacturer’s instructions
  • and has been tested for lead removal.

Treatment devices are now authorized to remove lead down to a concentration of 0.01 mg/L, although the technology is capable of removing lead to concentrations even lower than that.Many people will be able to meet the revised recommendation of 0.005 mg/L.The gadget’s manufacturer can be contacted if you have any questions concerning the device.Treatment devices must be maintained (or changed) in accordance with the manufacturer’s specifications.Due to the fact that water treatment systems require continuing maintenance, such as the replacement of filters on a regular basis, they are not considered permanent solutions.

Replacing lead service lines

The most efficient and long-lasting solution to decrease lead in your drinking water is to replace the lead service lines that bring water into your house as well as any lead interior pipes or fittings.When it comes to water service lines, most municipalities or water utility providers are solely liable for those that run up to and past the curb.It is the hom
