Practice English Speaking&Listening with: Black Berkey® Purification Elements: The Final Barrier against PFOA and Other PFCs in Drinking Water

Difficulty: 0

The EPA recently reported that drinking water supplies to more than 5.2 million Americans

are contaminated with a group of toxic chemicals known as Perfluorinated Chemicals (PFCs);

at levels higher than what the EPA deems to be safe for human consumption.

At, I want to help you understand critical information about PFCs,

and show you how Black Berkey® Purification Elements can help to safeguard your family's

drinking water.

What Are PFCs? What is PFOA?

PFC is the name given to a large family of chemicals called perfluorinated chemicals.

PFOA is a long-chain type of PFC.

All PFCs are man-made; they do not occur naturally in the environment.

All PFC molecules are composed of carbon to which fluorine atoms are bound; their molecular

structure gives them a slippery quality and the ability to repel other substances.

The difference between one PFC and another is determined primarily by chain length, or

the number of carbon atoms in its chemical makeup. There are two main groups of PFCs,

long-chain and short chain.

Longer chain PFCs such as PFOA and PFOS contains eight or more carbon atoms and are more persistent

in the environment and their health effects are well known.

Shorter chain PFCs contain 7 or less carbon atoms, have proven to be less persistent,

but their toxicity and effects have not been as thoroughly researched.

The two most extensively produced and studied long-chain PFCs are PFOA and PFOS and are

considered persistent organic pollutants.

This means they: - are extremely chemically and biologically

stable - remain in the environment and in the human

body, for long periods of times - are extremely resistant to breakdown when

exposed to air, water or sunlight, acid or other forces

- can travel long distances from their point of origin

Bottom Line: PFCs are not like other toxins. They have been identified as some of the most

persistent synthetic chemicals.

Where are PFCs Found?

Because of their unique chemical composition and ability to resist heat, water, dirt, grease

and stains, PFCs are found in a vast array of consumer and industrial products.

Consumer Products with PFCs:

Cookware (e.g. Teflon™, Nonstick) Food Containers or package such as French

fry boxes, pizza boxes, hamburger wrappers, and microwave popcorn bags

Personal care products Cosmetics

Paints and varnishes Stain-resistant chemicals

Water-resistant apparel Cleaning products


Industrial Uses for PFCs:

Engineering coatings Medical devices

Fire-fighting foam for oil and gasoline fires Insect baits

Printer and copy machine parts Oil production

Textiles, upholstery, apparel and carpets Paper and packaging

Rubber and plastics

Bottom Line: People can be exposed to PFCs by ingesting them; by drinking contaminated

water or eating contaminated food.

What are the Health Effects of PFCs?

When we consume food or water that contains PFCs, it is easily absorbed, begins to accumulate

in the body and the levels decrease very slowly over time.

Continued exposure to PFCs increases this level, resulting in potentially adverse health

effects. Studies in humans have shown that certain PFCs may be associated with the following:

developmental delays in the fetus and child, including possible changes in growth, learning,

and behavior decreased fertility and changes to the bodys

natural hormones pregnancy-induced hypertension and preeclampsia

increased cholesterol changes to the immune system

increased uric acid levels liver tissue damage

prostate, kidney, and testicular cancer

Bottom line: PFCs can enter your bloodstream through the air you breathe, through your

diet, through your use of nonstick products and other PFCladen items, or by drinking

tainted water.

Are PFCs in My Water?

Want to find out if the testing found PFCs in your drinking water?

The Environmental Working Group offers an interactive PFC Contamination Map that shows

every U.S. county where the chemicals were detected. Click on your county to see if your

water utility found any.

Your best protection against PFCs is to have a water purification system that is rigorously

tested to remove PFCs to below detectable levels.

Not all water filter systems have been tested to the extreme level that Berkey® Water Systems


Take a look at the test results. There's a link in the description you can click on to

see the results in more detail.

What These Tests Results Mean

Berkey® Water Systems contracted an independent lab to set the pre-filtered water concentration

of PFCs to one part per billiona level far exceeding those recently established by

the EPA.

The test results clearly demonstrate that the Black Berkey® Purification Elements remove

PFCs in water, down to the Extreme level of >99.9% at .002 micrograms per liter or two

parts per trillion.

That is the equivalent of one ounce in 7.5 billion gallons of water, or 1 square inch

in 250 square miles.
