A major investigation focused on widespread pollution by ‘forever chemicals’ called PFAS. It launched on the front page of the Guardian and involved seven stories over three days. Working with European media partners such as Le Monde and Süddeutsche Zeitung, and using data sourced by Watershed, we created a UK and Europe-wide map showing where PFAS pollution has been found.
We ran five further stories, one examining a PFAS manufacturer on the River Wyre where we had sampled for and found PFAS in high concentrations, a second on the PFAS legacy of a massive oil depot fire, the third was an explainer on the chemicals, the fourth examined solutions to the problem, the fifth looked at the political reaction to the stories, and a further story on PFAS was written by staff writers. Finally, we were interviewed about PFAS for the Guardian’s podcast.
