Initial Water Handling

The ECN protocol for initial handling of water samples (WH)


Protocol file


Site types that use this protocol


From the moment water samples are gathered they begin to deteriorate as a result of chemical and microbiological processes. Three methods of slowing this deterioration are used in ECN - filtration, cold storage, and (for Aluminium and iron determinations only) acidification.


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.
