This report considers the development of Environmental Quality Standards for the general ecosystem and special ecosystem uses. Biological assessment methods are reviewed that could be applied to measure the quality of waters identified for general ecosystem use and the suitability of methods as a basis for standards is considered. For rivers and canals, the use of invertebrate monitoring and RIVPACS is recommended as a basis for the derivation of standards. However, further testing of the RIVPACS model and application of BMWP scores is recommended. Also, the monitoring of other parts of the biological community should be considered and suitable techniques developed. A potentially useful technique for general habitat assessment, the Conservation Potential Index, has been developed in this project. For other categories of controlled surface waters further research is required to develop suitable methods, though approaches that enable natural variability in communities to be quantified such as the RIVPACS approach may be the most suitable.
