Arsenic is a naturally occurring mineral found in groundwater. Arsenic is a health risk and it is regulated in drinking water because long-term exposure to Arsenic in drinking water can cause cancer in the skin, lungs, bladder, and kidneys. As you can see in the chart at right, Arsenic is concentrated in specific regions throughout the United States.
Arsenic can be removed from drinking water using an under sink Reverse Osmosis system. These systems are highly effective and can reduce and remove other drinking water contaminants, including toxic chemicals (VOCs), tri-halo-methane, lead and other heavy metals, Fluoride, Sodium, Chlorine, tastes, and odors.
Arsenic can also be removed and reduced using a water conditioning system with special Arsenic reduction resin. This method is ideal for whole house filtration to enjoy filtered water from every faucet in your home.
Pretreatment with Chlorination is recommended to convert Arsenic 3 to Arsenic 5, followed by carbon filtration. A conventional water softener is also recommended with high water hardness and a particulate filter to remove suspended solids, if excessive. A properly designed system will remove 50 ppb of Arsenic to below 10 ppb.
