Title: Method for the assessment of river water quality using benthic macroinvertebrates
Author: National Rivers Authority Anglian Region
Document Type: Monograph
Abstract:
A differential response of river fauna and flora to varying water quality has been recognised for many years. Since the early sixties this response has been utilised by authorities responsible for river management as a convenient way of assessment of water quality. The methods have been developed to produce a means of classifying rivers in terms of water quality. Since water quality is not an absolute concept, the use of biota for its assessment has been found to be considerably more effective if used in a bcomparative mode. Biological assessment is complementary to chemical monitoring and is a useful indicator of the effects of pollution control. A select group of the river biota, the macroinvertebrates, has been found to be particularly suitable for this work. This group has become the most widely used section of the biota used for monitoring purposes. The advantage of these organisms is that they provide an integrated assessment of water quality and an audit of ecological quality.
