Análise do teor de flúor nas águas de abastecimento público [Title in english no available]

Abstract

There have being some controversies as to whether the fluorine level is maintained, as expected, at any point in a running water supply. ln the present research the Author tried to verify the occurrence or nonoccurrence of such variations through the resort of water treatment of Belém Novo, Porto Alegre, RS. For 15 days, in different periods of time, the Author analysed 450 samples of fluoridated water in six different points of Vila Restinga and Vila Nova Restinga. He compared the daily level rate obtained with those computed by the resort at the exit of the underground reservo ir. Thus finding no differencès statistically significant.
