HC Deb 12 May 1998 vol 312 c99W
Mr. Gordon Prentice

To ask the Secretary of State for Health if he will list the sources, in each case, of the fluoride used to fluoridate water supplies in England. [41004]

Ms Jowell

About half a million people in this country receive water which is naturally fluoridated at or about the optimum level of one part per million. A further one million people receive water which is naturally fluoridated at a lower level, but which still confers some dental benefit. Some 5 million people receive water where the fluoride content has been artificially increased to a level of one part per million. Information on the sources from which water companies obtain fluoride is commercially confidential and is not routinely collected by government.
