Analytical guidelines for water samples

Analytical guidelines for laboratories processing ECN water samples (WAG)


Protocol file


Site types that use this protocol


Water samples collected at ECN sites are analysed by several laboratories. Whilst each laboratory has full responsibility for managing its own analytical resources, participating laboratories have an obligation to conduct analyses under controlled conditions, and to provide documentation of methodology, information about significant changes in methodology, and information about validation procedures. This document sets out guidelines for laboratory water sample analyses.

Note: this was formerly the AG protocol.


Our field activities


Now that autumn has arrived the ECN fieldwork calendar begins to quieten down. We cease monitoring most terrestrial invertebrates apart from spiders. In rivers and lakes we make the last freshwater invertebrate survey of the year.
