Arsenic removal
from water

Removing arsenic from water in your home is paramount, particularly if levels are detected above the EPA limit. Arsenic in water has been linked to cancer of the bladder, lungs, skin, kidney, nasal passages, liver and prostate. Non-cancer effects can include thickening and discoloration of the skin, stomach pain, nausea, vomiting, diarrhea, numbness in hands and feet, partial paralysis and blindness.

There are different forms of arsenic in water, the determination of which will lead to the most effective and safe removal technique. You will need an accurate water test from a certified testing lab to reveal which type of arsenic is in your supply, therefore proper sampling protocol is critical. Arsenic is typically identified as ASIII (Arsenic Three) or ASV (Arsenic Five). The appropriate water technology and approach will be determined by the form of arsenic, pH and other impurities (competing ions) in the water. (To read an article we had published about arsenic in water removal in Water Technology Magazine, see the link at “Arsenic Removal: The Right Way”).

Arsenic Removal Tanks


Removal technologies include arsenic specific media, Reverse Osmosis, coagulation and oxidation. To remove arsenic at the point of entry into the home or building, a system containing arsenic-specific media is installed. The media inside the tanks will “grab” arsenic out of the water. For “point-of-use” drinking water, a reverse osmosis system can be installed to remove arsenic.

For point of entry removal, we recommend a dual tank approach in case the first tank’s media exhausts prior to the scheduled service date for replacement. It’s almost impossible to pinpoint exactly when that first tank will exhaust as it’s dependent on volume used plus the water chemistry, which can vary somewhat. Having a backup tank is the safest approach for a health threat such as Arsenic.

It is equally important that the system be plumbed in correctly and maintained properly with appropriate testing intervals.
