HC Deb 04 February 1974 vol 868 c234W
Dame Joan Vickers

asked the Secretary of State for the Environment, in view of evidence that there is a dangerous level of lead content in Plymouth domestic water supply, if he will have this matter investigated at the point at which it reaches the consumer, to ascertain whether it is within the limits considered safe by the World Health Organisation.

Mr. Rossi

As a matter of routine, water supply undetakings—and Plymouth is no exception—test the effectiveness of the treatment given to plumbo solvent waters by analysing for lead content samples of water taken from houses with lead pipes. Samples of water taken from such houses in Plymouth show a lead content within the limits recommended by the World Health Organisation.
