The mines have a long history of causing pollution and fish kills, and the owners were first prosecuted in 1890. The mines are a significant source of heavy metal pollution, particularly cadmium and zinc, in Gategill Beck and the River Glenderamackin, which fails to achieve 'Good' status for the North West River Basin Management Plan. The metal pollution also affects the River Derwent and Bassenthwaite Lake Special Area of Conservation (SAC) and Site of Special Scientific Interest (SSSI). The main source of metals is the Woodend Low Level but there is also diffuse pollution from waste spoil heaps. Please search for Threlkeld mines pollution to find out more.
