High levels of PFOA were found in discharge from a chemical plant. Is there any way that these chemicals can be removed from the environment? There are processes in place where if it's in the wastewater treatment process and water companies have something called granule-activated carbon as part of their process. But I was talking to one scientist and they're saying, well, they don't know that they can move all PFASs.
Madeleine Finlay speaks to environmental journalist Rachel Salvidge about PFAS, also known as ‘forever chemicals’, which have been found at high levels at thousands of sites across the UK and Europe. Rachel explains what they are, how harmful they can be, and what can be done to mitigate their effects. Help support our independent journalism at
