§ Mr. Tom ArnoldTo ask the Secretary of State for the Environment if he will list in theOfficial Report the definitions used in classifying river pollution and the name and classification of each river in the area covered by the North West river authority.
§ Mr. Heathcoat-AmoryThe definitions used in the current general river classification system in England and Wales are set out in detail in the report of the 1985 river quality survey, a copy of which is in the Library. The most recent information centrally available concerning the quality of individual rivers in the area until recently covered by the North West water authority (for which the north-west region of the NRA is now responsible) is also contained in that report.
