§ Mr. Gareth Wardell
asked the Secretary of State for Wales if he will give the most recent figures for the nitrate levels found in public drinking water supplies in Wales compared with acceptable standards.
§ Mr. Mark Robinson
The Welsh water authority annual report and accounts 1984–85—a copy of which is in the Library — indicates that all supplies of water passing into the distribution system were well below the 50mg/1 nitrate limit set by the EC Directive relating to the. quality of water intended for human consumption (80/778/EEC).
