-|Project summary=The Threlkeld mine was worked for lead and zinc between 1661 and 1928. The mine has a long history of causing pollution and fish kills, and the owners were first prosecuted in 1890. The mine is 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 Water Framework Directive. 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.

-Since 2010, we have been investigating the impacts from the mine with funding from Defra in partnership with the Coal Authority. Our monitoring confirms that the Woodend Low Level is one of the most polluting mine waters in the UK. Key findings from our monitoring are:
