HC Deb 16 December 1976 vol 922 cc828-9W
Mrs. Renée Short

asked the Secretary of State for Social Services what is his estimate of the number of people who are drinking naturally fluoridated water.

Mr. Moyle

I assume that the Question relates to areas where the water supply constantly contains fluoride naturally at about the optimum level for dental protection of one part of fluoride per million parts of water. The only notable instance in England is Hartlepool, where the water undertaking serves about 100,000. In several other areas this level of naturally occurring fluoride is not constantly attained, because of variations in water supply arrangements.
