Mersey suffers from major PFAS pollution

Watershed’s article in The Times reports that cancer-causing chemical loads flowing through the River Mersey catchment are among the largest recorded in the world and most of it is coming from sewage works. 

Compared with a number of river basins across the world, only the Tokyo basin carries more PFOA per square kilometre of land. For PFOS, the Mersey catchment is the third worst, after the Tokyo basin and Cape Fear in the US. The discovery was made by hydrologist Dr Patrick Byrne from Liverpool John Moores University, who monitored the Mersey for a year and calculated the forever chemical load travelling through the catchment.
