The Safe Drinking Water Act
requires EPA to revise the existing 50 parts per billion (ppb) standard for
arsenic in drinking water. On January 22, 2001 EPA adopted a new standard (read

, and public water systems
must comply with the .0010 milligrams per liter (mg/L) standard beginning
January 23, 2006. EPA is making clear that when a monitoring result is
expressed in milligrams per liter (mg/L) rather than ppb, that any monitoring
result greater than 0.010 mg/l is a violation of the January 2001 arsenic
standard. EPA has amended the arsenic Maximum Contaminant Level (MCL) to express
it as 0.010 mg/l.
In the United States, there are over 4,000 municipalities that have drinking
water with higher levels of arsenic more than the maximum contaminant limit (MCL).
Arsenic is widely distributed throughout the earth's crust, and is a problem in
some ground and well water. Arsenic contamination is largely the result of
minerals from weathered rocks and soils which become dissolved in ground water.
Although tasteless and odorless, arsenic is highly toxic and carcinogenic.
Long-term exposure to even low levels can be
detrimental to human health. Arsenic in drinking water has been
linked to cancer of the bladder, lungs, skin, and kidney, nasal passages, liver
and prostate. Ingestion of arsenic can also have non-cancer effects in the
cardio-vascular, pulmonary, immunological, neurological and endocrine systems.
Integrated Water Systems Arsenic
Treatment Platform incorporates ArsenX as its Arsenic removal media. ArsenX
technology requires lower capital than traditional technologies, is simple to
install and to operate, and doesn't require additional real estate or plumbing
for backwash purposes.
ArsenX Advantages:
It is considered a
GREEN
product – environmentally safe!
It's re-usable, which makes it
very cost-effective.
Has an optimum binding surface
area and great fluid mechanics, increasing efficiency.
Doesn't collapse or break down,
minimizing maintenance.
Backwash not required.
ArsenX media was developed by Purolite and SolmeteX. Purolite and SolmeteX scientists have developed and commercialized an innovative, cost-effective and reliable process for the safe removal of arsenic from municipal water supplies and private wells. Manufactured in the US and with NSF-61 approval for use in drinking water, ArsenX utilizes the advances in nanotechnology to prevent arsenic contamination. ArsenX is an ANSI/NSF 61 certified, iron oxide based media that utilizes nanatechnology to modify the surface chemistry to produce a sorbent media with the exceptional affinity and capacity for arsenic – both arsenate and arsenite
