January 20, 2021. Teton Conservation District drinking water quality map report at http://fluoridealert.org/wp-content/uploads/wy.teton-county-f-map.jan-20-2021.pdf

Excerpt: Page 6: Fluoride concentrations were available at 305 sampling locations and ranged from 0 to 20.2 mg/L, with the average of all values being 1.19 mg/L. The majority of the locations, however, had internal site average concentrations ranging from 0 to 0.6 mg/L, which is below 0.7 mg/L, the recommended concentration established to help protect against tooth decay. Eighteen sampling locations recorded higher than the 2 mg/L secondary recommended limit (nuisance standard), while nine recorded higher than the 4 mg/L EPA recommended maximum containment limit (health standard; Table 3). The majority of these locations were located in the southern portion of the county, in the vicinity of Red Top Meadows (south of Wilson) and Hoback, but some locations in and around Yellowstone also show elevated fluoride.

FLUORIDE POLLUTION SOURCES IN WYOMING:

In 2008, Wyoming ranked #29 out of 48 states for Hydrogen Fluoride releases (400,923 pounds). The following data comes from EPA’s Toxic Release Inventory (TRI). “Total releases” includes both water and air pollution. It’s important to note, however, that not all industries or sources that release fluoride into the environment are included in the TRI.
