§ Mr. Denis HowellThe Department has received representations from the London borough of Hillingdon and from one member of the public. I understand from the Rickmansworth and Uxbridge Valley Water Company that the failures of the copper piping followed the change in public water supply from a borehole to a River Thames source. The company is investigating the problem with representatives of research organisations concerned and my Deprtment has asked to be kept informed.
