HC Deb 13 January 1989 vol 144 c777W
Mr. Galbraith

To ask the Secretary of State for Scotland what information he has on the fluoride levels both natural and artefact of Loch Katrine water; and if he will make a statement.

Lord James Douglas-Hamilton

The natural fluoride content of Loch Katrine water is negligible and remains consistently below 0.05 milligrammes per litre. The water supply authority does not add fluoride.
