Análise da fluoretação da água de abastecimento público do município de Goiânia: relevância socioambiental

Abstract

The fluoridation of public water supply is one of the most effective alternative for combating dental caries in the population and is already considered a procedure of great importance in public health, in addition to having legal protection through specific laws and regulations. Water treatment plants are responsible for the adequate addition of fluoride ion in water for human consumption. However, accelerated urban growth in large cities can hinder water supply and consequently adequate water treatment. This study was developed in order to analyze the physical-chemical quality and fluoridation of public water supply in the city of Goiania, observing its socio-environmental relevance. For this purpose, 8 samples of Jaime Câmara Water Treatment Plants (João Leite) and Eng. Rodolfo José da Costa e Silva (Meia Ponte) were collected from November 2018 to May 2019. The analyzes were performed according to the recommended parameters CONAMA Resolution No. 357 of March 17, 2005. The results indicated limnological changes in the compounds called "oils and greases" and "sulfide" of the two stations. The fluoridation of the two analyzed stations followed the standards determined by CONAMA. The progressive growth of the Goiania microregion however suggests a future problem in the water supply of the region and a consequent setback in the adequate treatment of water for human consumption due to the increase of residues of the population
