Removing Arsenic from Water

Arsenic Levels in the US

What is Arsenic?

Arsenic is a naturally occurring mineral found in groundwater.  Arsenic presents a serious health risk.  It is regulated in drinking water because long-term exposure from drinking water can cause cancer in the skin, lungs, bladder and kidneys.  As you can see from the chart above, Arsenic is concentrated in specific regions throughout the United States.

How to Remove Arsenic from Water

Arsenic is effectively removed from drinking water using an under-sink reverse osmosis system.  These systems are highly effective against more than just arsenic.  They can also remove or reduce other drinking water contaminants, including toxic chemicals (VOCs), trihalomethanes (THMs), lead and other heavy metals, fluoride, sodium, chlorine, tastes and odors.

Arsenic can also be removed or reduced using a water conditioning system with special arsenic reduction resin.  This method is ideal for whole house filtration, in order to enjoy filtered water from every faucet in your home.


It is recommended to pretreat with chlorination, to convert arsenic 3 to arsenic 5, and then followed by carbon filtration.  A conventional water softener is also recommended when there is high water hardness, as well as a particulate filter to remove excessive suspended solids.  A properly designed system can reduce 50ppb of arsenic to below 10ppb.
