Arsenic IN WATER removal

Arsenic removal from the water supply in your home or business is extremely important for health reasons.  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 safest removal technique. You will need a water test from a certified testing lab to reveal which types and at what levels.  Proper sampling protocol is critical.  Arsenic is typically identified as ASIII (Arsenic Three) or ASV (Arsenic Five). The appropriate water filtration technology and approach will be determined by the forms of arsenic, pH and other impurities (competing ions) in the water supply.


Arsenic enters lakes, rivers and underground water naturally when mineral deposits such as rocks containing arsenic erode and dissolve. It may also enter the groundwater through the discharge of industrial and agricultural waste products.  If you live in an area previously used for agricultural purposes, residual  chemicals may have infiltrated the water supply,  Arsenic is an odorless, tasteless contaminant, therefore testing is imperative.

Arsenic Removal Tanks

Drinking Water Filtration

Reverse Osmosis Purification System installed under sink. Basement install optional.


Removal technologies include arsenic specific media, Reverse Osmosis membrane technology, 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 from your water supply

For point of entry removal, we recommend a dual tank approach as a precaution in the event the first tank’s media exhausts prior to the scheduled service date for tank 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. 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 with testing ports and maintained properly with appropriate testing intervals.  For more information on this, call us for a free consultation.
