This system has been tested for the treatment of water containing pentavalent arsenic (also known
as As(V), As(+5), or arsenate) at concentrations of 0.30 mg/L or less. This system reduces pentava-
lent arsenic, but may not remove other forms of arsenic. This system is to be used on water supplies
containing a detectable free chlorine residual at the system inlet or on water supplies that have been
demonstrated to contain only pentavalent arsenic. Treatment with chloramine (combined chlorine) is
not sucient to ensure complete conversion of trivalent arsenic to pentavalent arsenic. Please see the
Arsenic Facts section of this Performance Data Sheet for further information.
Pentavalent vs.Trivalent Arsenic Removal
These systems are very effective at reducing pentavalent arsenic from drinking water. These models were tested in a
lab and proven to reduce 300 parts per billion (ppb) pentavalent arsenic to below 10 ppb, the USEPA stan-dard for safe
drinking water.
RO systems are not as effective at reducing trivalent arsenic from water. These models will not convert trivalent arsenic
to pentavalent arsenic. If you have free chlorine residual in contact with your water supply for at least one minute any
trivalent arsenic will be converted to pentavalent arsenic and reduced by this RO. Other water treat-ment 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 the trivalent 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.
Maintenance
It is strongly recommended that you follow the maintenance instructions and have your water tested periodically to make
sure the system is performing properly. See replacement element information above for recommenda-tions on maintain-
ing your Reverse Osmosis drinking water treatment system.
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]. Al-
though 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. Addition-
al information about arsenic in water can be found on the Internet at the U.S. Environmental Protection Agency
(USEPA) website: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 wa-
ter 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.
