Most people in the U.S drink fluoridated tap water. However, water fluoridation has become a controversial hot topic in recent years.
This is because research and studies have raised questions about the need to fluoridate our drinking water. Rather unsurprisingly, several social activist groups petitioned the EPA to ban the addition of fluoride in tap water in 2016, citing all the potential health risks related to overexposure to the infamous element.
Needless to say, over 200 million Americans still drink fluoridated water and will continue to do so for at least a couple of years unless the government decides to halt the practice.
That said, fluoride levels in public but also private water supplies can vary, depending on factors like how much fluoride is added in the first place,
So, before you rummage to find safety measures, it’s wise to find out the concentration of fluoride in your water supply. How to test water for fluoride? Here’s a quick guide to help you.
Key Takeaways
These are the ways you can test your water for fluoride:
Most but not all major U.S. cities fluoridate their water. The easiest way to find out if your tap water is laced is to contact your local government or water utility. They should be able to tell you whether or not your tap water is fluoridated and by how much. Concentrations are usually measured in ppm or mg/L.
If you prefer to do your own testing for whatever reason or you use a private well, you can take matters into your own hands.
Here are the three most suitable ways to test fluoride concentrations in water.
The most reliable way to test your water for any sort of contamination is to conduct a professional lab test.
Apart from detecting the exact amount of fluoride in your very own home water supply, a lab test highlights the presence of all competing contaminants that are swimming in your water – if you pay for it. This key information helps you select the best method to treat your water, not just one contaminant.
However, you must look for an EPA-certified laboratory to ensure it follows protocol and withholds high levels of testing. We recommend: SimpleLab with their service Tap Score.

Alternatively, you can find a lab near you at the EPA’s website.
Once you have selected a lab, here is what you need to do:
If you are looking for the most economical and easy method to test your water, fluoride test strips are your best bet. They are easy to use and give results almost instantaneously.
All you have to do is dip a strip in a glass of plain tap or well water and hold it in for a few seconds.
Remove from the glass and wait for a minute before comparing it to the color chart provided on the packaging.
Similar to DIY fluoride water test kits, you can use a reactive testing kit at home easily. Here’s how to use it:
When talking about fluoridated water levels and their safety, we must consider two figures:
When municipal water supplies first started adding fluoride to their water – in the year 1962 – the recommended range was 0.7 to 1.2 milligram per liter. Today, it’s 0.7 mg/L as explained above.
The main reason for the decrease in fluoride levels was brought about after health experts pointed out that Americans now have access to multiple other fluoride sources.
Since fluoride is an element found in abundance in the Earth’s crust, it is also naturally present in almost all water bodies. Besides, foods rich in fluoride include spinach, grapes, and tea & coffee.
Over the past couple of decades, multiple studies have begun to challenge the assumptions about the need and safety of ingesting additional fluoride via drinking water.
The real problem nowadays is, fluoride is everywhere: For example in processed foods and beverages like soda, in dental products, and in some medicines too. This additional fluoride is what causes the real danger.
Here are a few potential problems that can arise due to the overconsumption of fluoride over a long time.
Almost 99% of fluoride that enters our body is stored in our teeth and bones. As a result, over-exposure can lead to discolored and disfigured teeth in children under six years.
Characterized by painful and stiff bones, skeletal fluorosis occurs when excess fluoride deposits in your bones.
Since 1% of fluoride makes its way to our brain cells, an overdose may cause sleep-related issues, fatigue, and depression.
Fluoride can suppress the function of the thyroid gland interfering with the hormones in your body. In bad cases, it may result in hyperthyroidism which opens up your body to a host of other illnesses.
