Fluoride

*Cambria, Friesland, Randolph, Wyocena & Harmony Grove do NOT add fluoride to their water. The water in these municipalities has insufficient fluoride for children's dental health. All other municipal systems in Columbia County are fluoridated. Do NOT take additional fluoride supplements if using fluoridated water.

*MOBILE HOME PARKS:

Fall View Estates - use fluoridated Fall River water
Riverview - use fluoridated Columbus water

Note:  This is not a complete list - test your water if you are not certain if there is fluoride in it. 

For more information on Fluoride see the Columbia County Health Fluoride Page..
