Why is Chlorine Present in Drinking Water?

Why should chlorine be present in our drinking water? It is for very good reasons, as the treatment and distribution of safe drinking water are considered by the U.S. Centers for Disease Control (CDC) as one of the major public health achievements of the twentieth century.

Towards the end of the nineteenth century it was found in London, UK, that water from a city well that had spread infectious diseases ceased to be dangerous after having been treated with chlorine.

Then in a few years the practice of water treatment was adopted by most of the civilized world as a means of protecting public health.

Up to those times drinking wine instead of water of dubious quality was the best assurance against illness, for those who could afford the expense.

Disinfecting the drinking water for human and animal use ensures that it becomes free of active microorganisms causing serious and life-threatening diseases, such as cholera and typhoid fever.

Chlorine is effective in killing most pathogenic bacteria and viruses. Chlorine however is not effective in killing certain protozoa like cryptosporidium.

The term chlorine refers to the chemical element Cl that exists as a poisonous yellow gas, irritant of the respiratory tract even at low concentration. As it is a very active element it is found in nature mostly as a compound, of which common table salt, sodium chloride (NaCl) is an example.

Chlorine gas is soluble in water. A common household product, bleach, is a water solution containing about 3 to 6% of sodium hypochlorite (NaOCl). This product too can be used to disinfect water in case of need.

Additional chlorination effects are the removal of iron and manganese and the residual property of continuing to hinder pathogen reproduction during the long way from the treatment facility to the house tap.

Is it safe to human health to drink chlorinated water?
It depends on whom you ask.

Some studies point to increased risk on health, while others show no additional risk.

It is generally recognized that drinking water chlorination is the process of choice for eliminating most of the life-threatening pathogens possibly present in the water reaching treating plants.

Some research efforts concentrating on the effects of certain by-products of the treatment, seem to suggest that substances like Trihalo-methanes (THM) have the potential to induce cancer in individuals as they do in laboratory animals when supplied at very high levels.

However it is commonly accepted that their presence in treated water in minimal quantities is far from threatening.

EPA regulates how much of these substances are tolerated in chlorinated water for safe use. The current EPA regulations establish a limit of 80 parts per billion (ppb), for THMs based on the annual average of eight distribution system monitoring locations.

Industrial and commercial sources, with deep interests in the use of chlorine and its derivatives, vehemently insist that independent medical sources failed to find statistically relevant results connecting chlorine with development of cancer diseases.

Other sources interpreting more strictly the results of certain research, seem to find concrete demonstration of the dangerous effects on health of chlorinated water.

Until more definitive research will authorize to settle the dispute by defining ways to sort the probable outcome of illness course according to additional contributing factors, it is possibly quite safe to assume that the present official standing of appointed authorities on water quality should be accepted except perhaps in unusual circumstances.

All sources agree that the benefits of chlorination for eliminating the presence of pathogens, are much greater than the minimal risk still remaining, if at all, relative to residual by-products.

The other existing means for obtaining a comparably safe result (ozonation, Ultraviolet light treatment, and use of chlorine compounds like chloramines and chlorine dioxide) are more expensive and do not provide sufficient advantages to promote their substitution.

It is suggested by professional experts that installing a suitable home filter at the point of use removes the nuisance of chlorine and byproducts from the drinking water.

Presentation Folders for Corporate Marketing

Folders are normally used to store important documents. But the role of folders doesn’t stop there. A presentation folder has a great part to portray in improving the growth of a business. Though most people use it to organize documents still it has become a great marketing tool that any business should not ignore.

Screen Capture Or Live Presentations?

If you have been involved in Internet marketing for a while, or for that matter just a few days, you can fail to have noticed that Video can play a major part in increasing your online presence.

Many people have tried in the past to create an online video, but I’m sure those who have tried will agree, that it is not as simple as some will have you believe. It’s just like anything else, it takes time and practice to get it right, and while I don’t think in all cases you need to produce a Hollywood type production, those who can produce a video with good basic video production techniques will succeed, while others are left behind in their wake.

Screen capture or Live Presentations

SCREEN CAPTURE – What do I mean by screen capture?… Basically it’s a method of recording the visual content of what ever you are doing live on the computer, and once the screen capture software is set up, it’s just a matter of clicking on record and you will start recording a video of what ever you want. Don’t forget you can also add a sound track and voiceover while your recording or later should you wish. This is probably the easiest way to get started with producing a video for viewing both on an internet web site, blog, or even to record for a CD or DVD

LIVE PRESENTATION – This has got to be the hardest of the 2 methods to get right, not only have you got to get the sound just right, you have to make sure you or who ever you are getting to do the live presentation, can actually pull it off.
I’m sure you have, or will see many Internet Marketers trying to do live video presentations themselves. Even those who are comfortable with live audiences such as at a seminar or workshop, just cannot quite cut the mustard when they stand or sit in front of a video camera. There is something that makes a video presenting or live video that is totally alien to most people, and that’s the fact that it’s the most unnatural thing you will ever have to do.

What I mean by that? – you may find yourself in a room alone with just a script to read from or teleprompter, a camcorder or webcam, and you have to speak to camera, just as if you are talking to someone else. It take time and practice, and I’m afraid it’s just a fact that most people simply will never be able to do it successfully, or to a degree that makes the viewer feel comfortable watching.

Recording the sound Live

It’s not always appropriate or necessary to record the sound track at the same time you produce the screen capture. Although many people seam to do this as standard practice, probably to save themselves time. It really is not good for the viewer to have to listen to anyone, no matter how interesting the topic or the person presenting, it’s really annoying to have to listen to all the umms and arrs. So if you can, I would always recommend you record the sound track separate to video.

Another trap that a lot of people fall into, is the belief that you should add the sound after you have recording the video track. This is in fact the hardest way to do it, it may take a little more planning, but the end result will be a much polished and better produced, more professional looking video by first recording the sound track, made up of the presenters voice, sounds effects and any background music.

By doing it in this order you will find the inclusion of still or moving video can easily be added to the audio content at just the right moment in time. At this stage any titles can also be added to enhance the presentation further.
