Quality Water Filters 4 You Posting Page

Private well owners may not realize that fluoride can be in their water, just as it is in most municipal water supplies. The reason is simple: fluoride is present in just about all sources of untreated water to some degree. That phrase "to some degree" is important.
The amount of naturally occurring fluoride in water varies wildly from one location to another and this applies to well water, too. The U.S. Geological Survey did a study in 2008 on well water and found that over four percent of those sampled had fluoride levels over the EPA Secondary Maximum Contaminant Level of 2 mg/L. Some wells tested at even higher rates, exceeding 4 mg/L.
While the number of private wells that have high levels of fluoride are small in comparison to the overall numbers, it is worth noting that fluoride levels can be much higher than many people suspect. And, again, this is natural forming fluoride, not fluoride that is added to the water after it had been treated.
As you may know, many people are concerned about the possible health effects of fluoride, especially as they apply to children. Many of today's toothpastes and mouth rinses have added fluoride to their list of ingredients. When this amount is added to the fluoride naturally present in well water, the total amount can be greater than is healthy for developing teeth.
Experts suggest that the optimum fluoride level in water for good oral health should be somewhere between 0.7 to 1.2 mg/L. Well water that has more than 1.2 mg/L can increase the risk of enamel fluorosis in children under the age of eight. Well water with levels above 2.0 mg/L should be treated before allowing children to drink it.
The only way to know how much fluoride is in your well water is to have it tested by a certified lab. Once you know what the level is, you can take whatever action is needed.
A very good option for homes that wish to limit fluoride in drinking water is to install in-home water filters that are rated to remove fluoride. This should not be done unless you are using toothpaste or mouth wash/rinse that has fluoride in it. The proper amount of fluoride is beneficial to developing teeth in younger children.
For an in-home point-of-use water filter to claim it can reduce fluoride, it must meet National Sanitation Foundation (NSF) Standard 58 criteria for fluoride removal.
