§ Dr. Miller
asked the Secretary of State for Scotland what research is taking place into the evidence of the connection between heart disease and the water supply particularly in the Glasgow area.
§ Mr. Gordon Campbell
Much research on this subject has been undertaken in many parts of the world, and the connection is fairly clearly established. The research was reviewed at a Meeting in October, 1969, a report of which was given in my Chief Medical Officer's "Health Bulletin" for July, 1970, of which I am sending the hon. Member a copy.
