§ Mr. Bestasked the Secretary of State for the Environment what number and proportion of the total 449W United Kingdom population live in areas which have concentrations of one part per million, or in excess, of fluoride naturally occurring in water supplies.
§ Mr. Giles Shaw:Many of the sources containing naturally one part per million or more of fluoride serve either small communities or are blended in the supply system with other water which is low in fluoride. A precise figure for the number of people receiving such water is not available but an estimate for England and Wales suggest half to three quarters of a million or some 1–1½ per cent. of the population.
