Abstract:
Each year, 22 estuaries in the region are classified in terms of their aesthetic, chemical and biological quality. In 1990 two surveys were carried out. Hie first (or "DoE Survey") was a repeat of the subjective assessment made in 1989 and previous years. This was based on the current NWC system of points allocation approved by the DoE/NWC Standing Technical Advisory Committee on Water Quality (Appendix 1). The second (or "NRA Survey") used the chemical data collected in each estuary during 1990 to provide a more objective classification for each estuary (using the same points allocation system as above). Every 5 years, the NWC classification is reported to the DoE to form part of the report of the national survey of river and estuary quality. This was last done in 1985. The 1990 NWC classification has been forwarded to the DoE.
