HC Deb 08 July 1955 vol 543 c127W
Mr. Viant

asked the First Lord of the Admiralty why men in the Navy are supplied with water to which fluorides have been added.

Mr. J. P. L. Thomas

No fluorides are added to water specifically for consumption by men of the Royal Navy. I understand that small quantities may be added to certain municipal water supplies in the course of controlled demonstrations being planned by certain local authorities in conjunction with the Health Departments, and it may be that some naval establishments will draw water from municipal supplies which have been so treated.
