AWWA B700-49 pdf download.The Fluoridation of Public Water Supplies
The water supply industry has al- ways been progressive in matters per- taining to public health and welfare. It has initiated extensive research on subjects pertaining to water quality and has been prompt to adopt new proc- esses and techniques when these have been found to improve the quality of public water supplies. It has coop- erated closely with public health agen- cies. The problem of caries control by the fluoridation of public water supplies has not followed the old patterns which have led to past changes and improve- ments in water supplies. Whereas pub- lic health agencies and the water works industry have generally agreed upon the changes to be made to produce bet- ter community health, the present de- mands for the fluoridation of water sup- plies are coming from the public and the press in advance of any final decision among public health authorities that artificial fluoridation will be effective against dental caries. • The water works industry recognizes these demands of the public it serves and wishes to coop- erate with civic and public health au- thorities, from whom it must receive direction, in the solution of the prob- lem of reducing dental caries.
One of the factors which further ex- perimental studies may be expected to reveal is what might be termed the cli- matological or geographical factor. It would be highly desirable to have number of additional fluoridation stud- ies in different states. These experi- ments should he so distributed geo- graphically as to provide specific in- formation on the optional concentration of fluoride, needed under particular climatological conditions. It is quite possible that more than 1 ppm. might be required in areas having a low mean annual temperature, such as the Da- kotas, while 0.5-0.6 ppm. might suffice where climatological conditions are reversed, as in the deep South or the Southwest.AWWA B700-49 pdf download.
