Every time untreated sewage is dumped in our rivers millions of microplastic particles also make their way into the water. When these discharges take place during low river flows, the microplastics settle on the riverbed, coated in a cocktail of chemicals and pathogens. These particles can be mistaken for food by hungry fish, thereby threatening fish populations and the wider river ecosystem.
Professor Jamie Woodward from The University of Manchester has been investigating just how deep this problem runs. It was his team's research that revealed the River Tame in Greater Manchester has the highest concentration of channel bed microscopic particles ever recorded.
Professor Woodward's research showed more than just the level of contamination. It revealed that the only way such high levels of microplastics could be found on the river bed was through the dumping of untreated wastewater outside of permitted conditions - that's because conventional sewage treatment is very effective at removing the microplastic particles from wastewater. Water companies dispute his findings, although he is world-renowned as a physical geographer with expertise in river catchment systems and his microplastic research has been published in Nature journals where peer review and editorial scrutiny are of the highest order. Two years after the publication of this work the water companies have not come up with a better explanation for these microplastic data.
DEFRA and United Utilities were invited to join us on this podcast to discuss the issue of microplastics, but both declined. You can hear their statements.
Professor Woodward asserts that untreated wastewater must be being discharged into rivers during low flows and dry weather. This is not permitted and should only happen in "exceptional circumstances". The implications of his work on microplastics are in good agreement with other independent studies of water company behaviour that have identified dry weather spilling of wastewater as widespread.
As we delve deeper into this pressing environmental crisis, we tackle the UK's consideration of a wet wipe ban and explore potential strategies to staunch the flow of microplastics at source. Professor Woodward's innovative sampling methods are put under the spotlight, and we grapple with the troubling role of microbeads from personal care products and industrial processes in contributing to microplastic pollution. We're not just here to expose the problem - join us as we champion the noble cause of cleaner rivers and consider practical solutions to this urgent issue. Tune in to this eye-opening discussion for an insight into the silent threat lurking in our waterways and how we can fight back.
