§ Mrs. Ann TaylorTo ask the Secretary of State for the Environment if he will give details of which of the standards set in the European Community drinking water directive are regularly exceeded by each of the water supplies in England which have been granted derogations.
§ Mr. Howard[holding answer 14 June 1989]: A list has been placed in the Library of those supplies which regularly exceed the EC drinking water directive in respect of the standard indicated and have been granted derogations by the Department under the terms of article 9 of the directive. Such derogations can be granted only where the situation is due to the nature and structure of the ground and there is no public health risk.
