U.S. Water Systems with High F Levels

Database of drinking water systems with high levels of naturally occurring fluoride; searchable by state.

Rhode Island (1993)

The Fluoride Action Network (FAN) has been unable to obtain the naturally occurring levels of fluoride in Rhode Island’s drinking water.

The Centers for Disease Control & Prevention’s (CDC) report titled Fluoridation Census 1992 accounts for the majority of data in FAN’s list of states for Naturally Occurring Fluoride Levels in U.S. Drinking Water. Unfortunately, the CDC’s 1992 Census did not list the natural levels of fluoride for Alaska, Arkansas, Hawaii, Kentucky, Maine, New York, Pennsylvania, Rhode Island, Tennessee, Vermont, and West Virginia.

FAN has tried, without success, to obtain the levels of naturally occurring levels of fluoride by state On EPA’s website, it states: “If you want the most up-to-date information about the current fluoride level in your water, contact your local water supplier directly.”

FAN will continue to seek the information for Rhode Island and will update this page when we have it.

The Oral Health Division of the CDC publishes an online list of fluoride levels in community water. This publication, called My Water’s Fluoride (MWF), notes that not all states report fluoride levels to them as the MWF is a “voluntary public disclosure web site. States choose whether they will provide their water fluoridation information to MWF. Some states choose to use other ways to notify the public about their water fluoridation program, such as a state web site.”

• The 23 states than do not provide info to MWF: AZ, CA, GA, HI, ID, MD, MO, MT, NV, NJ, NM, NY, NC, OH, OK, OR, PA, SD, UT, VA, WA, WI, WY


Please email Fluoride Action Network if you have information to share on levels of naturally occurring fluoride in Rhode Island’s drinking water.
