Mr. Meacher: To ask the Secretary of State for the Environment what monitoring is conducted (i) by his Department and (ii) on behalf
of his Department and agencies which report to his Department on the effects of the concentration of copper deposits in drinking
water supplies dormant for periods of over six hours. [40474]
Mr. Clappison: The Water Supply (Water Quality) Regulations 1989 require water companies to take a specified number of samples for
analysis for copper each year from consumers' taps in randomly selected properties in each of their water supply zones. The
specified number is between one and 24 samples per year depending on the size of the zone. The samples collected are the first litre
of water drawn off by the sampler. This water will have been in contact with any pipework, including copper pipework, for varying
periods including up to six hours and possibly more.
The results are provided annually to, and are audited by, the drinking water inspectorate. In 1995 the 31 water companies in England
and Wales analysed 10,616 samples for copper. All samples were within the standard in the regulations of 3,000 micrograms per litre.
