In the article, C&EN senior editor Marc S. Reisch explains that the technology - termed membrane filtration - also removes bacteria and chlorine-resistant parasites such as Cryptosporidium and Giardia. Starting with highly contaminated water, membrane filtration can produce potable water that can be purer than water from pristine reservoirs or deep artesian wells, the article notes.
Reisch describes a growing market for membrane filtration in Florida, Texas, California and other locales that must treat brackish water. Much of the demand in the United States results from increasingly stringent Federal regulations for drinking water drawn from surface sources. Demand for the technology also is strong abroad, especially in areas such as the Middle East that face severe water shortages and produce drinking water by desalination of sea water. A related C&EN story focuses on global chemical industry efforts to make safe, secure sources of drinking water more widely available.-American Chemical Society

Filtration resources & certification facts
Excellent story! Here are some valuable drinking water filtration
resources you can use in the future.
Solid carbon block technology is considered the most effective method
for reducing contaminants of health concern. In addition to the
removal of cysts, a solid carbon block filter also reduces:
· chemicals; MTBE, TCE
· pesticides;
· herbicides;
· disinfections byproducts;
· heavy metals;
· cysts; Crypto bug
· asbestos
· particulates
· chlorine.
. Arsenic

How do you choose a water filter? What does the filter actually reduce
or remove? And finally what does it cost? These answers are found by
doing a little research or home work will call it. Doing such will
save you a lot of money and provide you with pure "healthy" drinking
water. The bottom line is you must get a Data Performance Sheet by the
NSF national sanitation foundation to compare filters. These "proof of
performance" sheets show exactly what the filter does and for how many
gallons. If you can't get one from the manufacturer or from who ever
is trying to sell you one, simply say no thanks!

NSF International, The Public Health and Safety Companyâ„¢, a
not-for-profit, non-governmental organization, is the world leader in
standards development, product certification, education, and
risk-management for public health and safety. For more than 59 years,
NSF has been committed to public health, safety, and protection of the
environment. While focusing on food, water, indoor air, and the
environment, NSF develops national standards, provides learning
opportunities through its Center for Public Health Education, and
provides third-party conformity assessment services while representing

The Importance of Certification
In the last decade, interest in home water treatment products has
grown tremendously. Unfortunately, it isn't always easy for consumers
to know whether or not a particular product will actually be as safe
and effective as the manufacturer claims at reducing various
contaminants from your water supply.
NSF has a long history of developing and running independent product
testing programs. In fact, we are the leading independent tester of
home water treatment products on the market today. With our
state-of-the-art laboratories and highly skilled staff, we have the
knowledge and expertise to effectively evaluate water treatment
products, including:
Adsorption filters (i.e. carbon, charcoal, KDF, ceramic)
Reverse osmosis systems
Water softeners
Distillation systems
Ultraviolet disinfections products.
As an added assurance for consumers, NSF requires that all products
meet annual re-certification requirements. Unannounced plant
inspections and periodic retesting of all certified products are
required of all NSF-listed companies. This unique requirement allows
us to ensure that the products we certify continue to meet all stated
requirements year after year.
Note: NSF has tested & certified over 4000 different filters. It's
important to understand we have 400 plus manufacturers of water
filters alone world wide. Having said this "why" would you purchase a
water filter that is NOT tested & certified by NSF. It all comes down
to this: Talk is cheap and facts are hard to find in the drinking
water filtration industry! NSF is were you will get the facts.
Ultimately it comes down to this: What does the filter do & how much
does it cost?
NSF Data performance sheets is were to find "what it does".
Price: For a $1.00 a week you can have pure healthy drinking water. If
you are spending "more" it's costing you too much.
