§ Mr. Gordon Prentice
To ask the Secretary of State for Health what statutory provisions govern the responsibility of health authorities for decisions on water fluoridation. 
§ Mr. Milburn
The final decision on implementing fluoridation schemes rests with the water undertaker. The Water (Fluoridation) Act 1985 was consolidated in the Water Industry Act (1991) and Section 87 (i) of this states thatWhere a Health Authority have applied in writing to a water undertaker for the water supplied within an area specified in the application to be fluoridated, that undertaker may, while the application remains in force, increase the fluoride content of the water supplied by the undertaker within that area.
