These are all the known bacteria, viruses, molds, yeasts, and protozoa that can be killed by UV Light,
followed by the UV dose required to do the job. Scientists are still finding more with further
investigation. http://www.ultraviolet.com/microorgan.htm
How UV light works
When microbes are exposed to UV light, the nucleus of the cells absorbs the UV energy, which
“scrambles” the DNA structure. This sterilizes the cell and it can no longer reproduce. Thus, because it
cannot reproduce (which is how an infection takes off) it is considered dead and no possible threat.
The thicker the organism, the more light (contact time within the UV light chamber) is needed to reach
the organism’s DNA structures. Take giardia.
Giardia is a parasite that is much larger than any bacterium. It is a multi-cellular creature. The amount of
light needed to scramble the DNA in giardia is more than ten times that is used to kill the infectious
hepatitis virus and more than 20 times needed to kill the dysentery bacteria.
When it comes to water purification and water treatment, UV light kills many
more microbes than chlorination. The hepatitis virus can survive swimming around in chlorinated water
for a considerable time, but is quickly wiped out by UV Light.
Why are there no UV Light water treatment sites in this county? Actually, there are, but they are very
few. In the US, our chemical companies have way too much clout, or to put it in a way we can all
understand, they have more lobbyists than the UV light enthusiasts have.
What are the cons to Chlorination?
1.
The production of chlorine is energy intensive and wasteful.
2.
Byproducts of chlorine production are toxic to aquatic life.
3.
Byproducts are carcinogenic.
4.
Chlorine is a hazardous substance. Storage, transportation, and handling are a potential safety hazard.
5.
Chlorine is much less effective in deactivating virus than in deactivating bacteria, and still not as effective as UV Light in
deactivating both.
6.
Chlorine attacks your arteries and is a powerful contributing cause to Cardiovascular Disease and has been linked to
colon cancers.
7.
Chlorine in the blood forms calcium carbonate, the main cause of strokes (prior to the chlorination of water, Transient
Ischemic Attacks (TIA) and strokes were nearly unknown).
In a 1992 study that made front-page headlines, and was reported on in the July issue of the American Journal of Public Health
researchers at the Medical College of Wisconsin in Milwaukee found that people who regularly drink tap water containing high
levels of chlorine by-products have a greater risk of developing bladder and rectal cancers than people who drink un-chlorinated
water. The study estimates that about 9 percent of all bladder cancer and 18 percent of all rectal cancer cases are associated with
long-term consumption of these by-products. This amounts to over 20,000 new cases each year.
UV light is the Ultimate in water disinfection. (UV light only works on biological contaminants) Chemical contaminants need other
forms of filtration. A proper water analysis would help determine the right form of filtration needed for your potential situation.
Proper sizing (contact time needed) of UV light system is extremely important when buying a UV system for biological
disinfection.
"The drinking of chlorinated water has finally been officially linked to an increased incidence of colon
cancer. An epidemiologist at Oak Ridge Associated Universities completed a study of colon cancer
victims and non-cancer patients and concluded that the drinking of chlorinated water for 15 years or more
was conducive to a high rate of colon cancer."

Drinking Water Act in 1996 banned plumbing devices with pure lead pipe but still allows low
levels of lead. Homes built before 1986 are more likely to have lead pipes, fixtures and solder.
However, new homes are also at risk: even legally "lead-free" plumbing may contain up to 8
percent lead. The most common problem is with brass or chrome-plated brass faucets and
fixtures which can leach significant amounts of lead into the water, especially hot water.

Detected contaminants include caffeine, which was the highest-volume pollutant, codeine,
cholesterol-lowering agents, anti-depressants, and Premarin, an estrogen replacement drug
taken by about 9 million women. Also chemotherapy agents were found downstream from
hospitals treating cancer patients. Final results from the study are expected to be released in the
fall. For additional information about the U.S.G.S. study check the website:

Chloramine is a disinfectant put into many municipal water supplies. In recent years it has often
replaced chlorine for two main reasons. The first is that it is much longer lasting, so it continues to
provide a disinfectant action in supply pipes, where chlorine typically loses its capacity to
disinfect. The second is that it does not react with organics nearly as readily as does chlorine.
The reaction products of chlorine and organics (chlorinated organics) are very toxic to people,
and water supply operators elect to use chloramine to reduce this toxicity.

to rinse bacteria from the pipes before summer. During that time, officials said yesterday, lead
level test results in homes with lead service lines were 25 percent to 30 percent lower than they
would have predicted. (http://www.washingtonpost.com/wp-dyn/articles/A43649-2004May20.html)

15) Nitrate in drinking water is also associated with increased risk for bladder cancer, according to a
University of Iowa (UI) study that looked at cancer incidence among nearly 22,000 Iowa women.
The study results suggest that even low-level exposure to nitrates over many years could cause
increases in certain types of cancer, said Peter Weyer, Ph.D., associate director of the UI Center
for Health Effects of Environmental Contamination (CHEEC) and one of the study's lead authors.
The study was published in the May 2001 issue of the journal Epidemiology. "From a public
health perspective, source water protection is a main concern. Sources of nitrate which can
impact water supplies include fertilizers, human waste, and animal waste," Weyer said. "All of us,
rural and urban residents alike, need to be more aware of how what we do as individuals can
impact our water sources and, potentially, our health."
