1. These harmonized values were agreed upon by representatives of USEPA and Health Canada for the purpose of evaluating
products to the requirements of this Standard.
2. Influent challenge levels are average influent concentrations determined in surrogate qualification testing.
3. Maximum product water level was not observed but was set at the detection limit of the analysis.
4. maximum product water level is set at a value determined in surrogate qualification testing.
5. Chemical reduction percent and maximum product water level calculated at chloroform 95% breakthrough point as
determined in surrogate qualification testing.
6. The surrogate test results for heptachlor epoxide demonstrated a 98% reduction. These data were used to calculate an
upper occurrence concentration which would produce a maximum product water level at the MCL.

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 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. Information about arsenic in water can be found on the Internet at the US
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 PWC-670 system is designed to remove
pentavalent arsenic. It will not convert trivalent arsenic to pentavalent arsenic. The
system was tested in a lab. Under those conditions, the system reduced 0.050 mg/L
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 if the system is working properly. The RO
component of the PWC-670 system must be replaced every 20 months to ensure 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.
