Arsenic (As) is a naturally occurring contaminant found in many ground waters. 

Arsenic in water has no color, taste or odor. It must be measured by an arsenic 

test kit or lab test.

Public water utilities must have their water tested for arsenic. You can obtain the 

results from your water utility contained with in your consumer confidence report. 

If you have your own well, you will need to have the water evaluated. The local 

health department or the state environmental health agency can provide a list of 

test kits or certified labs.

There are two forms of arsenic: pentavalent arsenic (also called As (V), As (+5)) 

and trivalent arsenic (also called As (III), As (+3)). In well water, arsenic may be 

pentavalent, trivalent, or a combination of both. Although both forms of arsenic are 

potentially hazardous to your health, trivalent arsenic is considered more harmful 

than pentavalent arsenic. 

RO systems are very effective at removing pentavalent arsenic. A free chlorine 

residual will rapidly convert trivalent arsenic to pentavalent arsenic. Other water 

treatment chemicals such as ozone and potassium permanganate will also change 

trivalent arsenic to pentavalent arsenic. A combined chlorine residual (also called 

chloramine) where it does convert trivalent arsenic to pentavalent arsenic, may 

not convert all the trivalent arsenic in to pentavalent arsenic. If you get your water 

from a public water utility, contact the utility to find out if free chlorine or combined 

chlorine is used in the water system.

This Watts reverse osmosis system is designed to remove up to 98% of pentavalent 

arsenic. It will not convert trivalent arsenic to pentavalent arsenic. Under laboratory 

standard testing conditions, this system reduced 0.30 mg/L (ppm) pentavalent 

arsenic to under 0.010 mg/L (ppm) (the USEPA standard for drinking water). Actual 

performance of the system may vary depending on specific water quality conditions 

at the consumer’s installation. 

The RO membrane component of this reverse osmosis system must be maintained 

according to its recommended maintenance cycle. Specific component identification 

and ordering information can be found in the installation/operation manual 

maintenance section.
