Arsenic Fact Sheet
Background
Arsenic (abbreviated As) can occur naturally in well water. There are two forms of arsenic: pentavalent arsenic (also
called As(V), As(+5), and arsenate), and trivalent arsenic (also called As(III), AS(+3), and arsenite). Although both
forms are potentially harmful to human health, trivalent arsenic is considered more harmful than pentavalent arsenic.
In well water, arsenic may be pentavalent, trivalent, or a combination of both. Additional information about arsenic in
water can be found on the Internet at the U.S Environmental Protection Agency (USEPA) website at: www.epa.gov/
safewater/arsenic.html.
Testing Your Water
Arsenic in water has no color, taste or odor. It must be measured by a lab test. Public water utilities must have their
water tested for arsenic. You can get the results from your water utility. If you have your own well, you can have the
water tested. The local health department or the state environmental health agency can provide a list of certified
labs. The cost is typically $15 to $30.
Pentavalent vs. Trivalent Arsenic Reduction
This system is very effective at reducing pentavalent arsenic from drinking water. This model was tested in a lab
and proven to reduce 50 parts per billion (ppb) pentavalent arsenic to below 10 ppb, the USEPA standard for safe
drinking water. RO systems are not as effective at removing trivalent arsenic from water. This model will not convert
trivalent arsenic to pentavalent arsenic. If you have free chlorine residual in your water supply, any trivalent arsenic
will be converted to pentavalent arsenic and reduced by this Reverse Osmosis system. 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) may not convert all of the trivalent arsenic to pentavalent
arsenic. Water systems using an in-line chlorinator should provide a one-minute chlorine contact time before the
Reverse Osmosis system. 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.
Maintenance
It is strongly recommended that you follow the maintenance instructions in your owner’s manual and have your water
tested periodically to make sure the system is performing properly. See replacement element information above for
recommendations on maintaining your Reverse Osmosis drinking water treatment system.
