Water Filter System – Needed or Not?

The Ben Franklin plumber came by to do my annual water heater check. His company offers a Nature’s Miracle water filtration system. Information can be found at www.betterwaternow.com
Is this one of those snake oil water filtration systems that I shouldn’t watch out for?
Hi Kelly, thanks for writing in.
I had a look at the website for the Natures Miracle water filtration system. But before I get to that, there are some questions to ask yourself first.
Are you not satisfied with your current tap water? Is there a smell/odour that’s bothering you? Do you feel it’s unsafe for any reasons?
If you don’t have any issues with hard water when washing or doing laundry, don’t notice any bad odours or tastes from your municipal tap water, and drink it and cook with it without any second thoughts, then you don’t need any home water treatment.
It’s as simple as that.
What you should understand is that the USEPA, the American Water Works Association, the National Sanitation Foundation, the Ten States Standards and various governing bodies and other agencies work hard to ensure municipal tap water is safe.
Regulations are strict, and regular inspections by regulatory agencies ensure compliance.
The bottom line is that your tap water is safe. ANY home water system only improves the aesthetics of your tap water.
This natures miracle filtration system uses activated carbon, quartz (sand) and some sort of ion exchange resin. It’s some pretty basic technology packaged up nicely and probably priced much too high because of the clever marketing packaging.
I would watch out for any product that uses fear mongering tactics. Claims that municipal tap water is chalk full of all sorts of bad things that will make your body break out in more cancer cells than regular cells is much too hard a sell and is not true at all.
Most of the things they claim are in your tap water (if they were even there in the first place) would be removed by your treatment plant before getting to your house. Treatment plants use things like advanced oxidation techniques and activated carbon filters to ensure there are no volatile organics, pesticides, things of that nature in your water.
If there’s any lead in your water, this actually comes from the plumbing in your house. Old plumbing, old fixtures and old solder contain lead that can leach out into the water over a prolonged period of contact. This can be remedied by running your water for a minute or two to draw a fresh supply into your house. And that’s only if your plumbing is sufficiently old.
Chlorine is indeed an issue, but not at the 0.5 to 1.o part per million concentrations carried in most distribution systems. Even if this were an issue, when drinking your water your stomach acid neutralizes the chlorine. If you think it’s a problem, your cheapest solution is to keep water in a jug in the fridge. It won’t take long with air exposure for the chlorine to evaporate.
To wrap this up, your plumber is trying to sell you something you don’t really need. If there are any specific issues you are having with your water, I’d be happy to discuss them with you and point you in the direction of something that would fulfill your specific needs.
I hope I’ve answered your question. If you have any other questions or would like further clarification, please do not hesitate to write in again.

Mercury and Fluoride in Drinking Water
Published November 22, 2008 | Pat from San Diego, California writes:
I am fearful of drinking our tap water, as I have been hearing of the dangers of mercury in our water and its proliferation due to the Bush policies that have encouraged polluters to increase its concentration. But the last straw was when our local county boards started adding fluoride to our water. It was then that I started buying bottled water for all of our drinking needs.
Could you please tell me where I could take my drinking water for testing of these 2 pollutants?
Could you discuss what type of water treatment could be relied upon to remove mercury and fluoride?
I was very hopeful about buying a steam-condensing system and then I read your comments about distilled water (I presume that’s what such a system produces) and now I am fearful of distilled water too.
Hi Pat, thank you for your question.
I’d like to address fluoride first. Fluoride is an interesting chemical and has been the source of much debate among water purveyors and health professionals. While it is considered a toxic chemical in it’s concentrated forms, in trace amounts it is actually beneficial for the health and strength of teeth. Typically, water supplies that do not have a high enough naturally occurring fluoride concentration have been fluoridated to compensate for this. The argument is whether this is needed or not, as some feel there is enough fluoride in tooth paste and food items to provide for the bodies need for trace amounts of fluoride. The trace amounts of fluoride in your water will not harm you. In fact, you should check the label of the bottled water you have been using. Often, bottled water will contain as much or more fluoride as your tap waters.
I understand your concern of mercury. This contaminant is a dangerous one, and no doubt you have heard of Minimata Japan, where Minimata disease was first found, which is mercury poisoning. While mercury in your water supply is something to be concerned about, you should be much more concerned about mercury poisoning in fish.
When mercury enters a water supply, microbes can convert it to an organic form of mercury. Larger animals eat these microbes, and so on and so forth up the food chain in a process called biological magnification. This biological magnification causes a significant amount of mercury to be bound up in the muscle tissue of fish, who do not have the same capacity to remove trace mercury from their systems as mammals do.
Under the United States EPA, municipal water purveyors are required to test for mercury at a regular basis. If they detect a level above 2 parts per billion, they are then required to impliment measures to remove it as well.
Just to let you know, bottled water retailers are under no such regulation and can bottle anything they want.
Tap water is your safest alternative. Most people do not realize just how regulated municipal water is. In addition, those who sell home water products use fear mongering techniques to instill the unwarranted fear that tap water is not safe.
The municipality I work in has a policy of full disclosure. We provide detailed records of all water tests on our website, and will provide them upon request. Please do not hesitate to contact your municipality, they will be most likely be more than happy to provide test results on concentrations of mercury and fluoride.
If you still would like to test your water for contaminants at your own expense, contact the USEPA. They will be able to guide you to the closest licensed laboratory for drinking water testing. It is important to use a licensed lab, as they have met minimum quality guidelines.
Finally, please refer to this article on about.com:chemistry. It gives some useful tips about reducing fluoride from your diet from water as well as sources that are not from drinking water.
I hope I’ve answered your question to your satisfaction. If you have any other questions, or need further clarification, please do not hesitate to write in again.
