The EPA estimates that more than 13 million people in the United States drink water that contains arsenic. Arsenic is a naturally occurring element in the environment, and it can also be released into the air, water, and land through human activities.
Arsenic is a natural element with the symbol asan atomic number 33. It is a metalloid. It has many allotropes, but only the gray form is essential to industry. The main use of arsenic is in alloys of lead (for example, in car batteries and ammunition). Arsenic is a semi-metal.
Arsenic occurs in plenty of minerals, usually in combination with sulfur and metals. Arsenic is a metalloid that has various allotropes, but only the gray form is important to industry.
The main industrial use for arsenic is in alloys of lead, for example in car batteries and ammunition. Lead arsenate is used as a pesticide. Other uses include the production of glass and ceramics, pigments, and semiconductors.
Arsenic is highly toxic in its inorganic form. Organic arsenic compounds are much less toxic because they are poorly absorbed by the body. Inorganic arsenic compounds are used as pesticides and herbicides.
Arsenic and its compounds are highly poisonous and exposure to them can cause cancer and other diseases. Arsenic contamination of groundwater is a serious problem in many parts of the world.

How To Remove Arsenic From Drinking Water
In recent years, there has been an increasing concern over the health effects of arsenic exposure, particularly through drinking water. There are a number of ways to remove arsenic from drinking water, including:
1. Reverse osmosis
Reverse osmosis is a technique that uses a semi-permeable membrane to remove impurities from water. This process can remove up to 99% of arsenic from water.

2. Ion exchange
Ion exchange is a process that uses a resin to remove impurities from water. This process can remove up to 95% of arsenic from water.
3. Activated alumina
Activated alumina is a process that uses aluminium oxide to remove impurities from water. This process can remove up to 99% of arsenic from water.
Distillation is a process that uses heat to evaporate water and then condense the water vapour to create pure water. This process can remove up to 99% of arsenic from water.
5. Chemical oxidation
Chemical oxidation is a process that uses chemicals to oxidize arsenic in water, making it easier to remove. This process can remove up to 99% of arsenic from water.
Frequently Asked Questions
Am I at risk for arsenic poisoning?
Exposure to arsenic can cause cancer of the skin, lungs, bladder, and kidney. It can also cause other health problems, such as skin changes, stomach pain, nausea, vomiting, diarrhea, numbness in the hands and feet, paralysis, and blindness.
You may be exposed to arsenic if you drink water that contains it, breathe in air that contains it, or eat food that contains it. You can also be exposed to arsenic if you live in an area where there are high levels of arsenic in the soil or if you work in an industry that uses arsenic.
You can reduce your risk of arsenic poisoning by drinking only water that has been tested and found to be safe, eating a balanced diet, and avoiding exposure to arsenic in the workplace.
How do I test my water for arsenic?
The Environmental Protection Agency (EPA) recommends that you have your water tested for arsenic if you get your water from a private well. Arsenic can be found in different parts of the country, and it can enter your well water from natural sources or from contaminated groundwater.
If you get your water from a public water system, the water is regularly tested for arsenic and other contaminants. Public water systems must meet EPA’s drinking water standards.
You can have your water verified by a state certified laboratory. To find a laboratory, contact your state drinking water program or look in the phone book under “laboratories” or “water testing.” The cost of water testing varies, so you may want to call a few laboratories to compare prices.
At home test kits for arsenic are also available, but these kits may not be as accurate as tests done by a state certified laboratory.
What do the test results mean?
The EPA has set a maximum contaminant level (MCL) for arsenic in drinking water at 0.010 mg/L or 10 parts per billion (ppb). If your test results are above the MCL, you should take steps to reduce the level of arsenic in your water. You can find more information about treatment options in EPA’s brochure entitled Arsenic in Drinking Water:
What You Should Know:
If your test results are below the MCL, no further action is necessary. However, you may want to have your water tested again in the future to see if the arsenic level has changed.
What are the well-being effects of arsenic in drinking water?
Arsenic can have harmful effects on your health if you are exposed to it in high concentrations. Short-term exposure to high levels of arsenic in drinking water can cause stomach pain, vomiting, diarrhea, and cramping. Long-term exposure to arsenic in drinking water can cause cancer of the bladder, lungs, skin, and kidney, and can also cause other skin changes such as thickening and discoloration.
How can I reduce the level of arsenic in my drinking water?
If your water contains arsenic, there are several treatment options that you can use to reduce the level of arsenic in your water. Some treatment options remove arsenic from your water, while other treatment options reduce the amount of arsenic that your body absorbs.
You should contact your state drinking water program or a certified water treatment specialist to find out which treatment options are available and which option would work best for your home. You can also find more information about treatment options in EPA’s brochure entitled Arsenic in Drinking Water: What You Should Know.
Arsenic is a dangerous toxin that can have serious health consequences. If you are concerned about your exposure to arsenic, you should talk to your doctor and have your water tested. You can also install a water filtration system in your home.
