Author: National Rivers Authority
Document Type: Monograph
In order to protect our water supplies, our wildlife and the centre of much of our recreation, it is important to know the state of our rivers and to assess correctly which rivers have truly recovered and which need improvement. This report sets out one of the ways in which the quality of rivers in England an Wales will be reported and compared in future. It gives results which will form the baseline against which progress towards cleaner rivers will be measured. The NRA set out a way of classifying river quality which combines direct measurements of pollution with information on the biological life found in rivers . The classification may be used, as required by the Secretaries of State, for Statutory Water Quality Objectives issued under the 1991 Water Resources Act. It also allcws comparisons with the past and ensures a correct ranking of river quality in different parts of England and Wales.
