§ Mr. Harold Walker
asked the Secretary of State for the Environment what is the degree of pollution of the River Torne at Doncaster; and how this compares with the condition of the river before the establishment of the Coalite plant at Rossington.
§ Mr. Eldon Griffiths
Volume 1 of the Report of the 1970 River Pollution Survey classified the River Torne as264W Grade III. A supplementary survey, now in progress, will show the changes in river conditions since the 1970 survey.
