Arsenic Facts
Arsenic (abbreviated As) is found naturally in some well water.
Arsenic in water has no color, taste, or odor. It must be measured by
a laboratory 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. Information
about arsenic in water can be found on the internet at the U.S.
Environmental Protection Agency website: www.epa.gov/safewater/
arsenic.html.
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). In well water, arsenic may be pentavalent,
trivalent, or a combination of both. Special sampling procedures
are needed for a lab to determine what type and how much of each
type of arsenic is in the water. Check with the labs in your area to
see if they can provide this type of service.
Reverse osmosis (RO) water treatment systems do not remove
trivalent arsenic from water very well. 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) 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.
The RC250 system is designed to remove pentavalent arsenic. It
will not convert trivalent arsenic to pentavalent arsenic. The system
was tested in a lab. Under testing conditions, the system reduced
0.30 mg/L (ppm) or 0.050 mg/L (ppm) pentavalent arsenic to 0.010
mg/L (ppm) (the USEPA standard for drinking water) or less. The
performance of the system may be different at your installation.
Have the treated water tested for arsenic to check whether the
system is working properly.
The RO component of the RC250 system must be replaced
every 24 months to ensure that the system will continue to
remove pentavalent arsenic. The component identification and
locations where you can purchase the component are listed in the
installation/operation manual.
