This study includes a survey to estimate the health risks associated with possible exposure to hyper-fluoridated water. This survey aims to determine the groundwater quality in some rural centers of pre-rif of Taza region, focusing on fluorides, and assess the health risks associated with them. A hyper-fluorinated character was revealed in 73% of analyzed water (1.52 to 5.90 mg/L), with some contents which equals 2 to 4 times the guideline value (<1.5 mg/L). The survey among populations using these waters showed that 98% of 52 respondents are in contact with water containing fluoride concentrations above 1.5 mg/L. Thus, 75% of subjects have stained teeth of varying severity, while 17.3% complained of some signs that could be associated with skeletal fluorosis. Furthermore, the survey revealed an ignorance of the population of the problem of fluoride.
