an interaction between sunlight, salt in the water, and a chemical
element called Bromine. When these mix, the salty ice releases
bromine into the air and starts a cascade of chemical reactions
called a “bromine explosion.” These reactions rapidly create more
molecules of bromine monoxide in the atmosphere. Bromine then reacts
with a gaseous form of mercury, turning it into an ozone-eating
pollutant that falls to Earth’s

Fluoride Is Everywhere. Does It Make Sense to Keep Adding It To Water Supplies?
Most are aware that fluoride is intentionally added to a growing number of foods and products ostensibly for the protection of children's teeth. The following article, excerpted from Dr. Joseph Mercola's email newsletter, reveals a surprising source of fluoride that you might not be aware of.
Dr. Mercola's Introduction
Jeff Green has been an activist in the movement to
eliminate a toxic fluoride from your water supply for the past 15
years.With more than 60 percent of U.S. water supplies
currently fluoridated, chances are you're one of the 170 million
Americans who drink fluoride on a daily basis. In a previous interview, Green delved into the sordid
history that made water
fluoridation a reality in the first place. If you missed it, I highly recommend taking the time to watch
But fluoridated water is not the sole source of harmful
fluoride. Here, the discussion focuses on some of the lesser known
sources of fluoride exposure.
A Primary Source of Fluoride: Your Food!
While toothpaste and drinking water would appear to be
the leading sources of fluoride exposure, probably the most
common source of exposure is actually non-organic foods! The
reason for this is because of the widespread use of fluoride-based
According to Green, non-organic food could account for as
much as one-third of the average person's fluoride exposure!
This is important, as many people are under the mistaken
assumption that by avoiding fluoridated water, they've eliminated the
primary source of fluoride. But if you're still eating
conventionally-farmed foods, your fluoride exposure is still likely
is actually sodium aluminum fluoride... This sodium aluminum fluoride
is especially effective at killing bugs," Green explains.
"It's also very sticky, so when they spray it, it's more likely
to stick on your produce, unless you're... really working at trying
to get it off of it. As time has gone on, and... everybody said
fluoridation must be really great, they ramped up the amount of
residue [allowed on food] from these fluoride-based pesticides. They
have petitioned the EPA to be able to allow it, and they come out
with larger and larger [allowable] amounts."
Amazingly, based on the assumed safety of such
fluoride-based pesticides, iceberg lettuce can now contain a whopping
180 parts per million (ppm) of fluoride—that's 180 times higher
than what's recommended in drinking water!
assumption is that on a head of lettuce, you're going to peel off
those outer layers and you're not going to eat much of that. Whether
you do or not; that's up to you... Romaine lettuce and what we call
leaf lettuce are allowed to have 40 ppm, with the assumption that
it's down inside there and you're going to have to do more cleaning.
But because it's so sticky, it's almost impossible [to wash off]
unless you go back to the old ideas of the Fuller brush... produce
brushes that you... scrape this stuff off with. The majority of
people don't make that extra effort to be able to take it off."
Citrus fruits are allowed to be contaminated with 95
ppm's of sodium aluminum fluoride. Potatoes may have 22 ppm's on the
outside and up to two ppm's on the inside. Raisins can have up to 55
ppm's. But of all the foods, grapes are perhaps one of the
foremost sources of fluoride exposure.
Bet you would not have guessed that!
Grapes are a major source of fluoride because, first of
all, they're heavily sprayed with cryolite, and second, white grape
juice is typically used as the base, or filler juice in all sorts of
juice drinks. So if you drink any kind of juice on a regular basis,
you're probably getting hefty doses of cryolite, i.e. fluoride-based
pesticide... Cereals, mechanically deboned meats, and black or green
tea are a few other sources that may surprise you.
for example was measured at 10 parts per million," Green
says. "Shredded Wheat: 9.4 parts per million. Why is it so
high? One, they use pesticides on the grains. Two, they use
[fluoridated] water... So you actually have higher concentrations
than you ever found in the water where it was being made.
As for mechanically deboned meats, the source of the
fluoride is the animal itself, which is exposed in the same manner as
humans—through feed and water—which then comes out during the
manufacturing process. Black and green teas are naturally high in
fluoride, even if organically-grown without pesticides. This is
because the plant readily absorbs fluoride thorough its root system,
including naturally-occurring fluoride in the soil. According to
Green, there are reports of people who have developed crippling
skeletal fluorosis from drinking high amounts of iced tea alone.

Texas Comes in Fourth in "Most Polluted Waterways"Contest
Although Houston topped the list in a recent "America's Fattest Cities" listing, Texas as a whole was able to do no better than 4th in a
Texas Monthly study of the nation's most polluted waterways. Below is Sonia Smith's March 22, 2012 posting on the matter:
Texas waterways are the fourth most polluted in the nation, according to a new report from Environment Texas. Companies released some 14.6 million pounds of industrial pollutants and toxic chemicals into Texas’ waterways in 2010. Only waterways in Indiana, Virginia, and Nebraska received more industrial pollution.
“Texas’ waterways are a polluter’s paradise right now. Polluters dump 14.6 million pounds of toxic chemicals in Texas’ lakes, rivers, and streams every year,” Luke Metzger, director of Environment Texas, said in a release. “We must turn the tide of toxic pollution by restoring Clean Water Act protections to our waterways.”
Who is the worst offender? According to the report, Sanderson Farms Inc., a chicken company that handles everything from “production” to processing, dumped 1.5 million pounds of pollution—mostly nitrate compounds—into nearby streams.
Environment Texas drew up the report using water discharge data from the Environmental Protection Agency. Metzger pointed out that this report comes out as the Clean Water Act turns forty.

A Few Things You Should Know about Copepods
by Pure Water Annie
Copepods may not be high on your list of water issues unless your religious beliefs require use of kosher water. But non-Jews may also feel better about drinking and bathing in water that isn't teeming with little one-eyed crustaceans.
It is easier for a rich man riding a camel to pass through the eye of a needle than for a copepod to pass through a 20 micron filter.--Tiger Tom, Pure Water Gazette Columnist.
Copepods include several varieties of small crustaceans found both in the sea and fresh water. They live in the oceans, in ponds, in puddles, on plants, under wet forest leaves, attached to fish or corals--almost anywhere it's wet..
Copepods are typically 1-2 mm long, with
teardrop-shaped bodies and big antennae. They're so small that their bodies are almost totally transparent. In some areas copepods reach one centimeter in size, but they are usually
small enough to be invisible or barely visible to the human eye.
Although there has been of late the impression that there is an "infestation" of copepods taking place, truth is that copepods have always been around and they are important citizens of our ecosystem. It's just that we're becoming more aware of them. Public water reservoirs are also part of our ecosystem, so copepods could be expected to inhabit them. According to one source:
Reservoirs are essentially man-made lakes, and contain a regular ecosystem, including algae, copepods [and other micro-organisms, such as water fleas (Cladocera), rotifers, nematodes, ostracodes, amphipods, etc.] and fish. These are not infestations, but rather essential components of a healthy ecosystem. Copepods feed on algae, which would otherwise multiply and deplete the water of dissolved oxygen. They in turn are food for the fish. Planktonic copepods are present in reservoirs, lakes, and other bodies of slowly moving water throughout the world.
Copepods have been especially an issue in New York City. The reason is that NYC's water is very clean. Because it is so clean, the city is exempt from federal and state rules that require filtration of municipal water supplies. NYC water is chlorinated and fluoridated, but it otherwise goes to homes essentially in the condition it was in when it left the reservoir. To elaborate, cities that are required to filter their water, remove copepods with their filters, but in clean water cities like New York, San Francisco, and Boston the tiny creatures remain in the unfiltered water all the way to the consumer's home.
Copepods normally pose no risk to health in water from clean reservoirs, although they have been associated with such waterborne diseases a cholera in areas in South America and elsewhere where water is consumed untreated by chlorine. As for the religious issue, here's how Wikipedia explains it:
The matter of copepods in the water supply has raised a problem for Jewish people who observe Kashrut in that copepods, being crustaceans, are not kosher, and are not small enough to be ignored as non-food microscopic organisms (since some specimens can be seen with the naked eye). The discovery of copepods in the New York water supply in the summer of 2004 in particular caused significant debate in rabbinical circles and caused many observant Jews to buy filters for their water.
In parts of Africa, guinea worms attach themselves to copepods and cause infections when when ingested by the native population. This is prevented by use of nylon mesh as a filter. The nylon filter is approximately 150 microns, but it is tight enough to filter out the copepods (and consequently the guinea worms).
According to one source, "An old cotton sari, folded, creates a smaller effective mesh size (approximately 20-μm). This should be small enough to remove all zooplankton, most phytoplankton, and thus a large proportion of the cholera in the water (99%, according to laboratory studies)." The nylon mesh proved to be almost as effective as the folded sari.
The moral is that copepods aren't hard to filter out. Any good 20 micron filter is more than tight enough to grab them if you want to remove them from water entering your home.

||Modern cartridge-style filters with a 20 micron cartridge provide assurance of copepod-free water.
