Kingston University has been invited to play a key role in an ambitious mission: making the River Thames clean enough to drink.
The initiative, called Mayors for a Drinkable Thames, brings together local councils, mayors, and community groups across several boroughs, including Kingston, Richmond, Hounslow, Spelthorne, Elmbridge, and Runnymede. Their shared goal? To restore the health of the Thames, a river that’s not only central to London’s identity but also vital for commuters, businesses, wildlife, and thousands of everyday users—from rowers and sailors to families enjoying riverside walks.
At Kingston University, scientists from the School of Life Sciences, Pharmacy and Chemistry will take on the task of analyzing pollutants in the water. That means testing for everything from heavy metals, pesticides, and microplastics to pathogens and even traces of medicines and recreational drugs. Alongside them, a University College London team will model pollution and track sewage outflows, making the data accessible through an online platform.
By combining this science with local knowledge, the project aims to build a predictive model of river health. That model could help community groups—like Sea Scouts and outdoor education centers—plan safer activities and give residents more confidence about using the river.
The timing couldn’t be more relevant. Public concern over sewage spills has been rising, as have debates about how water in England should be regulated. A recent government review even suggested creating a single national water regulator, as well as stricter oversight of pollution, including from farming, microplastics, and so-called “forever chemicals.”
For Kingston University, the project fits perfectly with its mission to support sustainability and community wellbeing.
The Mayors for a Drinkable Thames project also links to a broader European movement. Similar efforts are already underway with the Mayors for a Drinkable Meuse initiative in France, Belgium, and the Netherlands. Both projects tie into four of the United Nations’ Sustainable Development Goals, underlining their global importance. Photo by Andrew Smith, Wikimedia commons.
