How Much Fluoride Is In a PPM (Part Per Million)?
Have you ever wondered exactly how much fluoride is in your drinking water? Usually fluoride is measured using the vague unit ppm. The abbreviation ppm stands for parts per million.
Let's say that you run a test to find out how much fluoride is in your drinking water and you find that the fluoride level is 2 ppm. That means that for every one million units of water, there are two units of fluoride.
The main problem with this measurement is that it's pretty hard for most people to actually visualize one million units of anything.
It's much easier to understand the fluoride content of water through the use of measurements that are more easily visualized and understood by our brains.
With that in mind, I've come up with some examples to help you visualize what one ppm of fluoride really represents. I decided to use one ppm of fluoride since that is the average fluoride concentration in most fluoridated water.
I've used the rough estimate available from a few different sources online that there are about 90,000 drops of water in a gallon. I'm also assuming you have pure fluoride in liquid form (which is a bit of a stretch, but use your imagination!)
How Much 1 PPM of Fluoride Really Is
If you poured 11 gallons of milk into a large container and added one drop of fluoride, you would have a concentration of 1 ppm of fluoride.
If you poured 21 2-liter bottles of Coca-Cola into a large container and added one drop of fluoride, you would have a concentration of 1 ppm of fluoride.
If you filled up an average size bathtub with water and added five drops of fluoride, you would have a concentration of 1 ppm of fluoride.
If you added 1/4 cup of fluoride to an average-sized pool (14 feet by 28 feet by 5 feet deep), you would have a concentration of 1 ppm of fluoride.
If you combined 28 and a half gallons of fluoride with all of the water that flows over Niagara Falls in an hour, you would have a concentration of 1 ppm of fluoride.
Hopefully with the previous examples, you can see that there is no exact answer to the question: How much fluoride is in a ppm?
The amount of fluoride varies along with the amount of the substance in which it is found. A standard that is usually mentioned in dental textbooks is that 1 ppm is when there is 1 milligram of fluoride in 1 liter of water.
The amount of fluoride in our water is small, but it can go a long way in reducing tooth decay.
