Author: A.H. Place
Document Type: Monograph
Abstract:
During the year to the end of June 1992, 568 sites were routinely monitored to assess the quality of 3820 km of river. Table 1 gives details of 87 sites which failed their RQOs representing 493 km of river (12.9% of the total). However, 287 sites, representing 1807 km (47%), achieved water quality better than their objectives. This represents a slight improvement in overall quality since the last report. Table 2 gives details of the class achieved by all reaches. Table 2(a) is a matrix showing the total lengths of river in each class against objectives, while Table 2(b) shows this graphically.
