Climate change, rising urbanisation and agricultural intensification lead to global depletions of safe drinking water resources, and consequently reinforce the need for comprehensive monitoring frameworks.


A new exciting bacterial genome study on the River Cam has just been published in the journal eLife (“Freshwater monitoring by nanopore sequencing” by Urban, Holzer et al., The study was a collaboration of many University of Cambridge departments along with the  European Bioinformatics Institute, Wellcome Genome Campus.

In a case study, published 19 January in the journal eLife, an interdisciplinary research team at the University of Cambridge now exemplifies uses of the world’s smallest, smartphone-sized DNA sequencing device (MinIONTM, Oxford Nanopore Technologies) to monitor hundreds of different bacteria in a river ecosystem.

From the beginning, this project was done and led in an open way, involving citizen science workshops, pub talks and lots of student initiative ( Beyond the local findings regarding potentially nasty bugs in the Cam, The article provides many guidelines on cheap and simple water quality monitoring using genetics.
