According to the Centers for Disease Control and Prevention (CDC), fluoride is a mineral that occurs naturally in all water sources, including rivers, lakes, and groundwater. It is also added to public water supplies to help prevent tooth decay. The CDC recommends that all public water supplies contain at least 0.7 milligrams of fluoride per liter of water (mg/L).
The United States Public Health Service recommends that all public water systems add fluoride to their water. This is because fluoride helps prevent tooth decay, which is a major problem for both children and adults. The amount of fluoride in water varies depending on where you live.
In general, the level of fluoride in water should be between 0.7 and 1.2 ppm (parts per million).
Fluoride Levels in Water by City
Fluoride is a mineral that occurs naturally in many water sources, including rivers, lakes, and the oceans. It can also be added to public water supplies to help prevent tooth decay. The level of fluoride in water varies depending on where you live.
Here is a list of average fluoride levels in water by city:
City Fluoride Level (ppm)
Atlanta, GA 0.7
Baltimore, MD 1.2
Boston, MA 0.9
Buffalo, NY 1.1
Charlotte, NC 0.8
Chicago, IL 1.0
Denver, CO 1.3
El Paso, TX 0.6
Fort Worth, TX 0.8
Fresno, CA 0.7
Honolulu, HI 0 ppm (fluoride is not added to the public water supply)
Houston, TX 0.8

What is the Level of Fluoride in Drinking Water?
Fluoride is a mineral that occurs naturally in many waters and is added to others. The level of fluoride in drinking water varies depending on the source of the water and whether it has been treated. Community water systems add fluoride to their water to help prevent tooth decay.
The amount of fluoride added to community water systems is regulated by the Environmental Protection Agency (EPA).
The level of fluoride in well water depends on the geological formation through which the groundwater has passed. Some minerals, such as calcium and magnesium, can bind with fluoride and make it less available for absorption by the body.
Other minerals, such as silica, can increase the solubility of fluoride and make it more available for absorption. The pH of well water can also affect how much fluoride is absorbed by the body. acidic waters tend to have higher levels of dissolved fluoride than basic or neutral waters.
The EPA has set a maximum contaminant level goal (MCLG) for fluoride in drinking water at 4 mg/L. This goal is not enforceable, but rather serves as a guide for communities when considering adding fluoride to their public drinking supplies. The EPA has also set an enforceable maximum contaminant level (MCL) for fluorides in public drinking water at 4 mg/L .
Water systems that exceed this MCL must take steps to reduce their levels of fluorides .
While some people believe that there are health benefits associated with consuming low levels of fluoridated drinking water, others are concerned about possible adverse health effects from exposure to too much Fluoride . A 2006 report from the National Research Council concluded that “it is apparent that infants who drink formula reconstituted with optimally fluoridated tapwater may be exposed daily to more than 100 times greater amounts [of Fluoride ] than what would trigger” dental fluorosis , a condition marked by white spots or streaks on teeth .
Studies investigating potential links between exposure to high levels of Fluoride and other health conditions have had mixed results, and further research is needed before any conclusions can be drawn .
How Much Fluoride is in a Glass of Tap Water?
The level of fluoride in a glass of tap water can vary depending on the source of the water. For example, according to the National Sanitation Foundation (NSF), levels of fluoride in surface water can range from 0.01 to 4.0 mg/L, while levels in ground water can be as low as 0.002 mg/L or as high as 10 mg/L. The U.S Environmental Protection Agency has set the maximum contaminant level for fluoride at 4 mg/L.
With that said, a 2008 study by the Centers for Disease Control and Prevention (CDC) found that the average level of fluoride in tap water across the United States was 0.7 mg/L. So, if we assume that the average level of fluoride in tap water is 0.7 mg/L, then a glass of tap water would contain about 0.035 mg of fluoride.
How Much Fluoride is in Bottled Water?
Fluoride is a mineral that occurs naturally in many water sources, including bottled water. The amount of fluoride in bottled water varies depending on the source of the water and the treatment methods used. Most bottled waters contain some fluoride, but the levels are usually much lower than what is found in fluoridated tap water.
The United States Environmental Protection Agency (EPA) has set an enforceable limit for fluoride in public drinking water at 4 milligrams per liter (mg/L), or 4 parts per million (ppm). This level is based on the best available science to prevent tooth decay. Some communities add fluoride to their public drinking water to help reach this level, while others do not need to because their natural levels are already at or above 4 ppm.
The FDA has no legal limit for fluoride in bottled water, but they encourage manufacturers to list the fluoride content on the label if it exceeds 0.6 mg/L. Bottled waters that contain added fluorides must be labeled as such and state the exact concentration of fluoride added.
So how much fluoride is actually in bottled water?
It depends…but it’s often less than what you’d find in public drinking water, and sometimes there is no added fluoride at all. If you are concerned about your exposure to fluoride, check the label before you buy or contact the manufacturer directly with any questions.
Does Tap Water Have Fluoride in It?
Yes, most tap water in the United States is fluoridated. This means that it contains a small amount of fluoride, which can help prevent cavities.
How Much Fluoride Should Be In Your Water?
Conclusion
Fluoride is a mineral that occurs naturally in many water sources, including rivers, lakes, and oceans. It can also be found in some ground water supplies. Fluoride is added to public water supplies to help prevent tooth decay.
The level of fluoride in drinking water is regulated by the Environmental Protection Agency (EPA). The EPA has set the maximum contaminant level goal for fluoride at 4 milligrams per liter (mg/L) or 4 parts per million (ppm). This means that if the levels of fluoride in a public water supply exceed 4 mg/L, the water utility must take steps to reduce the levels.
The amount of fluoride that people are exposed to from drinking fluoridated water varies depending on the level of fluoride in the water supply and how much water they drink. Studies have estimated that people who drink fluoridated water containing 1 mg/L of fluoride could receive an average dose of 0.7 mg/day of fluoride from drinking 2 liters (about half a gallon) of fluoridated water per day. Children who drink more than 2 liters of fluoridatedwater per day could receive doses greater than 0.7 mg/day depending on their age and weight.
A 2008 study found that children living in areas with high levels of naturally occurring fluoride in their drinking water had lower IQ scores than children living in areas with low levels of naturally occurring fluoride.
