Title: Procedure for quality assurance for RIVPACS compatible macro-invertebrate samples analysed to the taxonomic level needed for the BMWP-score system
Author: Environment Agency
Document Type: Monograph
This document describes the quality assurance procedures for all macro-invertebrate samples collected in accordance with the standard methods for RIVPACS and analysed to the level required by the BMWP-score system. This includes samples for which the principal analysis will be to BMWP level but where some taxa have been identified further, either particular groups, or taxa whose further identity is readily apparent. This includes samples collected for GQA, as well as samples collected for other strategic and operational purposes. The purpose of this Environment Agency document is to provide standardised procedures for the quality assurance of macro-invertebrate samples collected by procedures compatible with RIVPACS and analysed to the level needed for the BMWP-score system. This includes samples analysed for General Quality Assessment (GQA).
