Abstract:
This report focuses on the biological monitoring of rivers that was undertaken in 2001 by the Environment Agency (The Agency) in England and Wales, the Scottish Environment Protection Agency (SEPA) in Scotland, the Industrial Research and Technology Unit (IRTU) in Northern Ireland and the Government Laboratory in the Isle of Man. The collection of standard macro-invertebrate samples and their analysis to the level required for the Biological Monitoring Working Party (BMWP) system is the most widely used biological technique for evaluating river quality in the water industry in the United Kingdom. Used with the computer model RIVPACS (River Invertebrate Prediction and Classification System) developed by the Centre for Ecology and Hydrology (CEH), they are the basis for the Agency's biological classification of water quality. This is used for national General Quality Assessment (GQA) river quality surveys and one of the governments Headline Indicators of environmental quality, as well as for purely operational purposes including Catchment Abstraction Management Strategies, drought orders and drought permits, and determining appropriate discharge consents. These samples are also used for assessing pollution and setting priorities for capital investment.
