[Determining the optimal fluorine dose in the drinking water of the South Center hydrological region of Haiti]. / Détermination de la dose optimale de fluor de l'eau destinée à la consommation humaine de la région hydrographique Centre-Sud de la république d'Haïti.

This study aims at determining the optimal dose of fluorine in the drinking water in the South Center region of Haiti. This region has an average daily temperature ranging from 17 to 33 C. Water samples were collected from November 15th to December 20th 2000 on the water resource of some of the counties of the hydrological South Center region of Haiti. The results show that the concentration of fluorine in this region varies between 0 and 0.83 mg/litre. However, the calculated optimal dose based on the temperature measured show that fluorine concentration of water should be between 0.7 and 1 mg/litre.
