How To Remove Arsenic From Drinking Water: A Step-by-step Guide

Arsenic is one of the byproducts of mining, coal burning, and smelting. It occurs naturally in soil and rocks. Arsenic can enter water supply in a community through natural deposits in the earth. When the ground level drops drastically, arsenic can find it’s way into water by dissolving from rocks.

Too much exposure to water to arsenic can cause skin, bladder, kidney, and cancer. It can also cause pigmentation in the skin. In areas where drinking water is highly exposed, it can be contaminated with arsenic, and the effects is seen in a lot of individuals in the community.

Natural arsenic is found in the crust of the Earth. In humans, arsenic is a carcinogen and can cause cancer.

These technologies remove arsenic via adsorption and ion exchange, which require a water pre-treatment to remove organic matter that binds to the arsenic.

It might not surprise that arsenic is a poisonous substance, but people have been using it for a long time to make their food taste better or kill pests.

There is an increase in the cases of lung and bladder cancer caused by arsenic in drinking water. It is therefore fitting that you know how to remove arsenic from water at home.

Where and How Does Arsenic Get Into Drinking Water?

Arsenic is a metal-like substance that is found in small amounts in the environment. It occurs in groundwater as a natural element. Arsenic in groundwater is as a result of contamination that is caused by the release of hazardous wastes from industries that use arsenic in their production.

Where And How Does Arsenic Get Into Drinking Water?

Arsenic can get into drinking water in two major ways. One is through mineral deposits. These mineral deposits contain a high level of arsenic, and groundwater flowing through these minerals can dissolve the arsenic. When the groundwater dissolves the mineral deposits, arsenic finds its way into the well, thereby entering into your drinking water.

The other way arsenic can get into your drinking water is y having contact with hazardous wastes. Some industries use arsenic in their production, and the waste materials from these industries can get into the water, transmitting arsenic into the water. Arsenic is used in wood preservatives, in pesticides, and glass, improper disposal of this waste can contaminate groundwater with arsenic.

Arsenic generally has no smell, color, or taste. This makes it challenging to know if your water contains arsenic. The only way to tell if your water has arsenic is to test the water.

What are the concerns?

Ingesting arsenic groundwater can cause severe health problems (and even death) over time – as much exposure as possible increases the risk of lung cancer, heart disease, diabetes, amputations, and renal failure.

In addition, arsenic affects human development at all stages of life. Arsenic exposure during pregnancy can result in heart malformations, brain damage, deafness, blindness, skeletal deformities, and mental retardation. The effects on fetuses and infants who ingest contaminated breast milk are also severe.

How to Remove Arsenic From Water at Home

How to Remove Arsenic From Water at Home

Once you suspect that you have a risk of arsenic poisoning, you need to have the water tested to be sure. If your water comes from a private well or groundwater, you should have it tested for arsenic. After testing and confirming that arsenic is present, several methods exist to remove arsenic from water at home.

Reverse Osmosis Systems 

Reverse Osmosis water filtration is a method used to filter out arsenic from water. It helps to reduce arsenic concentrations in well water. RO doesn’t always reduce arsenic concentrations to the barest minimum level, but a safe point for drinking.

Reverse Osmosis Systems

Reverse Osmosis is a process that allows water to pass through a semi-permeable membrane under pressure but leaves contaminants behind. This provides the home with clean and healthy drinking water. RO process can get rid of arsenic, alongside other pollutants like lead, cysts, in water.

However, proper maintenance of the RO system should be regularly to ensure arsenic filtration works appropriately.

Anionic Exchange Systems 

Anionic exchange system operates by allowing water to pass through a resin bed, which removes arsenic and exchanges it with a non-toxic substance in water. The anionic exchange unit is installed at the point of entry of water into the home. The process is more of like an exchange program. The arsenic exchanges it’s spot on the resin bed with a less toxic and harmful substance.

Anionic Exchange Systems

This process effectively removes arsenic in the water, but a pre-treatment can be needed sometimes. The anionic exchange system is easy to operate and inexpensive to maintain. The resin bed needs to be cleaned frequently, depending on the quality of the resin and the water. If the system is not adequately maintained, the arsenic may detach from the resin bed and find it’s way back to the water at a higher level.

When the anionic exchange removes arsenic and other contaminants from water, they remain on the resin bed until lt is backwashed and flushed to a drainage system. The water treated by this system may be corrosive because of the presence of high chloride concentration and low pH levels.

Iron Oxide Filter Systems 

Oxidation is a precipitative process that removed naturally occurring iron and contaminants from water. This process involves the oxidation of the soluble forms of the pollutants to their insoluble forms and then remove them by filtration. Arsenic and iron occur in their reduced form in groundwater. And for proper removal of the arsenic, both the iron and the arsenic has to be oxidized simultaneously.

There are two primary means to remove arsenic from water. These are adsorption and coprecipitation. After oxidizing the iron and arsenic, the arsenic adsorbs into the iron hydroxide precipitate and filter out of the water. This method’s removal of arsenic increases the water’s pH level. Iron removal plants are also an effective means of removing arsenic from water.

Coagulation, Precipitation, and Filtration

Coagulation and filtration are the most highly documented method of arsenic removal from water. Coagulation uses three mechanisms to remove arsenic from water. These methods are precipitation, co-precipitation, and adsorption.

Coagulation, Precipitation, and Filtration

Precipitation is the formation of insoluble compounds in water; co-precipitation is the incorporation of a soluble arsenic sample into a growing metal hydroxide phase. Adsorption is the binding of soluble arsenic to external surfaces of insoluble metal hydroxide. Coagulation has been used over a long period to remove arsenic from water. It is an effective method.

Coagulation is one of the most well-known methods in removing arsenic from water. PH controls the removal of arsenic in water by coagulation and works best at low pH.


The toxic chemical arsenic can cause problems with the nervous system, liver, and kidney. Distillation is a method that does this, which removes the arsenic from water by boiling it. Distillation is when the potentially toxic substances in water are separated from the pure water vapor.

Ancient civilizations have used distillation for thousands of years, and is even mentioned in the Bible.

The low-cost technique of arsenic removal is distillation. Arsenic can be removed through this process by boiling the water with organic material, such as charcoal or wood ash.

Safe water technology

Safe water technology for arsenic removal is a process that consists of three steps:

(1) pre-filtering the water,

Pre-filtering involves filtering the water before arsenic removal takes place. Pre-filters are usually made up of sand, gravel, or crushed rock. Filters are placed in front of the arsenic treatment unit to prevent impurities from entering it.

(2) removing the filtrate using ion exchange resins, and

Removing the filtrates is done by passing the water through ion exchange resins. Porous materials with negatively charged sites on their surface are ion exchange resins. Calcium and sodium ions, such as those found in seawater, are drawn from the water through the resins. Arsenic will be released back into the waste stream once it has attached itself to the resin.

(3) post-treatment with an acidic solution.

Post-treatment involves treating the filtered water with a caustic solution. Caustics are chemicals that react with metals, including arsenic, and form insoluble salts. Here, the treated water is passed through the second set of resins, which will absorb the arsenic once more.

In developing countries, where arsenic contamination is common, these methods are safe. The use of hazardous chemicals makes them unsuitable for developed nations.


Biomaterials for arsenic removal is a list of names and types of biomaterials used in the process of arsenic removal.

Biomaterials are natural or manmade substances that help us live longer and healthier lives. The most commonly used biomaterials include activated carbon, iron oxide, zeolite, and chitosan.

Activated carbon

Activated carbon is an inexpensive material that is commonly used for arsenic removal. Activated carbon is a type of carbon that has undergone a high-temperature process. This process causes the carbon atoms to become bonded together, making them more stable and less reactive.

Sand Filters

Sand filters are made from coarse sand, which is unique in that it can filter out large particles yet still allow water to flow. Solids, heavy metals, and other contaminants are filtered out using sand filters in wastewater treatment plants.

Arsenic removal using sand filters works by allowing the water to pass through the sand slowly. The sand, as it passes through the water, traps any arsenic present in the water. After the water has been filtered, the sand is then discarded.


Electrolysis is the process of breaking down elements into smaller components. This process occurs when electricity is applied to a component. When the electrons of an atom move away from the nucleus, they cause the atom to lose its electron configuration. Through this process, new compounds are formed, called cations and anions.

Sorptive Filtration Processes

Sorption is the process of attracting and holding onto a solid surface. In this case, the solid surface is activated charcoal. The adsorbent properties of activated charcoal make it useful in removing many types of chemicals.

In sorptive filtration, a liquid containing arsenic is passed over the activated charcoal. The arsenic binds to the charcoal, thus preventing it from entering the water.

How to Test Arsenic in Water at Home

Testing for arsenic in water wells has always been difficult since it has no odor or taste. Estimating arsenic concentrations in water accurately is left to be carried out in the laboratory with advanced equipment. This laboratory process takes time, and it is expensive. Several test kits have to be in place to get this test done.

How to Test Arsenic in Water at Home

The test kit has a plastic bottle, and that is what you use for the process. The arsenic sample and all other reagents combine in the reaction vessel, and you use a test strip to measure the arsenic concentration in the water sample. The test strip is placed over the sample, and as the arsenic converts to arsine gas, the indicator on the test strip changes from white to yellow and brown.

After the test, the test strip is matched to a color comparator chart and the measure of arsenic taken. Arsenic test kits are expensive but are accurate in testing for arsenic in water.

How to remove arsenic from well water

Arsenic removal from well water poses a difficult challenge. There are two ways to remove arsenic from well water. You can either use a chemical treatment or an adsorption process.

By using chlorine dioxide as a reagent, the arsenic in the water is chemically reacted with. Oxidation removes it from the water and leaves behind harmless chemicals like oxygen and chloride.

Nevertheless, this method does not always work as well as other methods, especially due to the additional cost and time it takes to use chlorine dioxide every four months. Adsorption is a second method that is cheaper and lasts longer than adsorption.

You need to purchase a filter cartridge containing activated carbon to do this. Activated carbon will absorb any impurities present in your drinking water. Once the cartridge becomes saturated with contaminants, simply replace it with another one.

How to remove arsenic from rice water

An element of toxic chemical nature, arsenic can often be found mixed in water. It’s most concentrated in the rice water, so people in Bangladesh are at higher risk. If you decide to remove arsenic from rice water, you should understand the associated health risks before proceeding.

There are four main methods for removing arsenic from rice water:

Distillation: This method separates liquids by boiling them and condensing them back down to their liquid form. This removes all contaminants like arsenic, but the process is time-consuming and cost-prohibitive.

Lime Washing: Uses alkaline solutions created by quicklime, calcium oxide, and sunlight to react with arsenic, forming arsine gas that evaporates. While effective, lime washing takes up to three days to complete.

Activated Carbon Filters: This method involves filtering contaminated water through filters made of activated carbon. When these filters become full, they must be replaced. The cost is cheap and the installation is easy, but they do not eliminate arsenic contamination.

Chromatography Columns: Chromatographic columns separate different types of molecules based on size and weight. As long as there isn’t enough arsenic in the sample, chromatography columns should effectively remove it. Unfortunately, they aren’t very efficient at doing so.

How To Make Your DIY Filter That Removes Arsenic

A DIY filter that removes arsenic can be made with two materials: activated charcoal and sand. Carbon is extremely porous, and activated charcoal has an extremely high porosity. It is used in many different industries to absorb bad smells, toxins, pesticides, and chemicals.

To remove arsenic from water, place 1 inch of sand in the bottom of a container, then charcoal on top of the sand. The top layer should be an inch or so of sand covered with activated charcoal. The filter should be kept in direct sunlight until it dries out completely before use.

The first step in making a DIY filter to remove arsenic is to find a large plastic jug or bucket. This will serve as the base of the filter. Next, fill the jug halfway with sand. Then add about 1/4 cup of activated charcoal. Finally, place another 1/4 cup of sand over the activated charcoal.

Next, cover the entire filter with a piece of clear plastic wrap, sealing all edges tightly. Place the filter in direct sunlight for several days, turning it every once in a while to ensure even exposure. Once the filter has dried, remove the plastic wrap and discard.

Now that the filter is ready, it’s time to test it. Add a few drops of tap water into the jug. If the water turns cloudy immediately, the filter is working properly. If not, try again.

Once you’ve successfully tested your DIY filter, keep it in a safe location where children cannot access it. Use it regularly to remove arsenic from drinking water.

Common myths about Arsenic Removal Techniques!

In some parts of the world, arsenic contaminates drinking water supplies, causing serious health problems. It is usually found in the form of arsenic trioxide or arsenic pentoxide. Among other things, arsenic is a by-product of mining, smelting, and refining processes.

Common myths about arsenic removal techniques:

  1. There are no effective methods for removing arsenic from drinking water!
  2. Electrocoagulation is effective at treating groundwater for arsenic!
  3. Chlorine is not effective at removing arsenic from drinking water!
  4. Reverse osmosis is an effective method for removing arsenic from drinking water!
  5. Ion Exchange Columns are ineffective at removing arsenic from drinking water!
  6. Iron oxide nanoparticles are ineffective at removing arsenic from drinking water!
  7. Activated Carbon Filters are ineffective at removing arsenic from drinking water!

A Biomaterial-Based Approach for Arsenic Removal from Water

To remove arsenic from water, the researchers came up with a biomaterial-based approach. A biomaterial is a material made from living organisms, such as bacteria and algae. The researchers used Seawater Green Algae, or SGA, as a biomaterial.

SGA is a type of algae that naturally produces arsenic-binding ligands, which help extract the chemical from water. The study showed that this process was able to remove up to 98% of arsenic from water.

Household Sand Filters for Arsenic Removal

Household sand filters are used to remove arsenic from drinking water. In groundwater and other sources, arsenic is a naturally occurring element but at very low levels. Using sand filters to remove arsenic from drinking water can reduce exposure to this element. The sand filters in household water are not effective in removing all arsenic.

Arsenic Removal from Drinking Water During Coagulation

There is an element known as arsenic that can occur in drinking water. Coagulation is the process of removing arsenic-containing compounds from water.

Arsenic removal during coagulation can take place in several ways, such as:

  • Adsorption: the adsorption of arsenic onto other substances like clay or aluminum oxide.
  • Chemical precipitation: the formation of a new compound by the deluge of an arsenic salt from solution.
  • Dissolution: the dissolution of arsenic compounds into smaller molecules so they can be more easily filtered out of the water.
  • Filtration: the filtration of arsenic-contaminated water using materials like sand or activated carbon.

A very effective way to avoid exposure to arsenic is to avoid drinking water with high amounts of arsenic. If you must drink water with high levels of arsenic, then you can use a filter to remove arsenic.

Removal of Arsenic by Water Hyacinths

Water hyacinths can remove arsenic from groundwater by the process of phytoremediation. These plants use their roots to absorb arsenic in soils, releasing oxygen and organic matter to the soil. In addition, the plant’s leaves and stems also contain high levels of iron, which helps oxidize arsenic. The plants also help bind the arsenic in water, removing it back into the atmosphere

5 steps of Arsenic removal from drinking water using granular ferric hydroxide

  1. Granular ferric hydroxide needs to be mixed with the water and stirred for 30 minutes at a temperature of 80 degrees Celsius.
  2. The solution is then filtered and placed in a container.
  3. The pH of the solution is adjusted to 8 with hydrochloric acid and then stirred for 30 minutes at a heat of 80 degrees Celsius.
  4. The solution is then filtered and placed in a container to store it.
  5. The water is then treated by the following steps: filtration, pasteurization, and boiling.

Health Risks Associated With Drinking Water Contaminated With Arsenic

There are two types of health risks associated with arsenic in drinking water. The first type is the cancer risk, which occurs when the concentration of arsenic in the body reaches a certain level. The second type of risk is anemia, which happens when arsenic replaces iron in the body. Both of these risks increase if the person has been exposed to arsenic over a long period.

Cancer Risk

People should avoid drinking water with more than 10 micrograms per liter of arsenic. Dehydration can occur if people stop drinking water altogether; however, according to the WHO. Arsenic-exposed people should limit their consumption to 50 micrograms per liter or less.

Anemia Risk

People who have been exposed to arsenic over a long period may develop anemia. Anemia is more common in areas with naturally occurring arsenic in the ground or the air than in areas without clean drinking water.

Sources of Arsenic in Drinking Water

There are many sources of arsenic in drinking water. Some common sources include:

Natural Sources

These include the presence of arsenic in rocks and minerals that are found underground.

Industrial Sources

This includes mining activities and smelting operations that release arsenic into the environment.

Municipal Wastewater Treatment Plants

Cases are added to treated water at some municipal wastewater treatment plants to reduce bacteria. Sometimes, other chemicals are added, such as calcium carbonate, zinc chloride, and chromium trioxide. The chemicals become concentrated in the form of arsenic compounds in the water.

Other Sources

When people drink well water, they also ingest arsenic through food. For example, some foods contain arsenic. These include rice, seafood, mushrooms, and vegetables.

Does Boiling Water Get Rid of Arsenic?

While boiling, evaporation occurs, and the arsenic concentrations increase as the water boil. Most people think since boiling water can get rid of other contaminants like bacteria, then it should get rid of arsenic. But nothing can be farther from the truth. Boiling water doesn’t get rid of arsenic in water wells.

33. Does RO filter remove arsenic?

Reverse osmosis filtration systems use high-pressure pumps to force water through membranes made of polyamide. These membranes allow only certain molecules to pass through. Arsenic is among those molecules that cannot penetrate the membrane. As a result, the arsenic stays behind in the waste stream.

34. What amount of arsenic causes health effects?

The U.S. government’s maximum contaminant level for arsenic in drinking water is 10 ppb. In the United States, individuals who consume water with concentrations above 5 ppb are at risk of developing skin lesions, bladder cancer, and lung disease.

35. What else can I do to prevent arsenic besides filtering my water?

Yes! You can install a system that uses ultraviolet light to kill bacteria and viruses. UV disinfection systems are effective against many types of pathogens, including bacteria, protozoa, and viruses. The most common form of UV disinfection uses ultraviolet C radiation. It has been shown to eliminate more than 99% of all microorganisms in water.

Useful Info for Definition may help:

Long-term exposure

Long-term exposure to inorganic arsenic can lead to health effects, mainly from drinking contaminated water and consuming food prepared with it. Chronic exposure is already linked to a higher risk of skin cancer and may cause stomach pain.

As a result of long-term exposure, risks for bladder cancer, leukemia, and lung cancer also increase. Atypical bacteria play an important role in causing bladder cancer, especially in children. Skin cancers and other health issues such as leukemia can be caused by high-level exposure.

Surface water

Arsenic is naturally present in water that originates from surface water or groundwater. Arsenic would be flushed into subsurface waters by rainfall and soil erosion upon landing. It does not occur in this manner because arsenic can enter surface water before reaching the bottom.

Private wells

Private wells may be contaminated with various types of chemicals or pathogens. To minimize contamination of drinking water, private wells should be tested for contaminants regularly.

Water quality

Chemically, arsenic is toxic and can be found in water. The water quality may cause serious health problems such as cancer and congenital disabilities if not treated properly. These arsenic test kits detect the amount of arsenic in water to be bottled and consumed without harming people’s health.

Water testing

Many water testing kits can be purchased and used to test water for arsenic content. The following resources provide testing information:

Partial paralysis

As a metal that occurs naturally in the environment, arsenic can also enter water sources from land runoff. Arsenic can cause poisoning and other health effects despite its carcinogenic properties, including paralysis, allergic reactions, cancer, and death, even at low doses (0.01 g/L).

Calcium ions react with it, causing precipitation on surfaces where calcium channels of nerve cells are blocked, causing partial paralysis. Arsenic is a toxic metal that may be found in rocks, soils, and groundwater.

Groundwater can flow out to surface water through broken pipes or open depressions, shale pits, gutter overflows, and seepage from landfills or other sites where it has been released into the environment.

Hydrogen peroxide

One method to remove arsenic from water is via hydrogen peroxide. It may be used in freshwater, seawater, and industrial purposes. Arsenic decomposes hydroperoxide into non-toxic metal ions such as hydroxyl (OH) and hypochlorous acid (HOCl). Compounds such as these are known as oxidants because they promote the oxidation of organic substances.


Having access to clean water is essential to human health. The source of water most people have has a risk of being polluted by several pollutants, of which arsenic is one of them. Arsenic is known to be a very harmful chemical that gets in contact with groundwater. It occurs naturally through mineral deposits and finds its way to pollute water.

If you do not remove arsenic from water, it can cause cancer, skin infections, and death. A lot of processes have been put in place to get arsenic out of the water, but it takes chemical processes to get it out effectively. Many people do not know how to remove arsenic from water at home, which can become dangerous to the body.
