In this report, the following definitions apply:- (i) Chemical Classes of Rivers Details are given in 3.1 at the back of the book. Classes are:- 1A Water of high quality suitable for potable • supply and capable of. supporting hign class game fisheries; 1B Water of less high quality than 1A, but suitable for substantially the same purpose. 2 Water suitable for potable supply after advanced treatment and capable of supporting reasonably good coarse fisheries. * 3 Water polluted to such an extent that fish are absent or only sporadically present. 4 Water grossly polluted and likely to cause a nuisance. (ii) River Quality Objective (RQO) Long term quality objectives, adopted by the then Severn-Trent Water Authority in 1979, in which all i major rivers and canaJs were classified having regard to their uses and environmental impact and which formed the basis of long-term pollution control strategy. (iii) Classification of Details are given in 3.2 at the back of the book classes Estuaries are:- A Good Quality B Fair Quality C Poor Quality D Bad Quality (iv) E C Directives Membership of the European Community by the United Kingdom imposes obligations to comply with Directives issued by the European Commission. The Directives referred to in the report are given in detail in Section 4.
