Title: 1996 general quality assessment (GQA) Cornwall area
Author: Environment Agency South West Region Devon Area
Document Type: Monograph
Annotation: EA additional title info: south west regional pollution prevention and control September 1997
Abstract:
This report contains the results of applying the chemical GQA Scheme to data collected during 1994-1996 from the freshwater stretches of rivers in Cornwall; these results are referred to as the 1996 assessment. This assessment uses all routine chemical samples taken between 1 January 1994 and 31 December 1996 as part of the annual GQA monitoring programmes. The results of the last biological GQA, carried out in 1995, have also been included within this report. Summary information concerning the derivation of the GQA chemical classification (Table 1), statistical methodology associated with this scheme (Table 2), and the derivation of the GQA biological classification (Table 3) are given below. Area summaries for attainment both 1996 GQA chemical grades (Table 4) and 1995 GQA biological grades (Table 5) are expressed by length (km) and as a percentage of total length.
