Author: Environment Agency South West Region Devon Area
Document Type: Monograph
Annotation: EA additional title info: December 1998
This report is divided in two parts. The first part contains the results of applying the chemical General Quality Assessment (GQA) scheme to data collected between 1995-1997 for the freshwater rivers and canals in Devon. These results are referred to as the 1997 chemical GQA. This assessment uses all routine chemical samples taken between 1 January 1995 and 31 December 1997 as part of the annual GQA chemical monitoring programme. A comparison with previous water quality is presented and it identifies significant GQA upgrades and downgrades between 1994-6 and 1997(calendar year). This information provides a statistically robust view of whether water quality is getting better or worse over time, and will help to target resources. The second part of the report contains the results of applying the River Ecosystem scheme to the rivers and canals data for Devon collected between 1995-1997. The River Ecosystem scheme provides a nationally consistent basis for setting river quality objectives (RQO's) and for reporting compliance with them.
