River Coquet 29. Mr. Beith asked the Secretary of State for the Environment whether he is satisfied that serious levels of pollution will not arise in the lower reaches of the River Coquet and in the sea off Amble this summer. Mr. Marks The lower reaches of the River Coquet are shown as class 2 in the River Pollution Survey and no scientific evidence is available on the condition of the sea off Amble. I have no reason to expect any serious increase in pollution in either this summer.
