The problems facing water are complex, with multiple sources of pollution affecting water quality. One of the lesser-known areas of the Environment Agency's work is cleaning up pollution from abandoned metal mines.
Mining played a major part in Britain's rich industrial history, but this also left thousands of abandoned mines scattered across our landscape. Almost all these mines had closed by the early 1900s but they are still releasing harmful metals including lead, cadmium and copper. This is one of the top 10 issues for water quality in England as it harms fish and river insects. Abandoned mines are the largest source of metals to British rivers and seas (click here for more information). Pollution is localised to about 1,500km of rivers - mainly in the North East, Cumbria, Yorkshire & Cornwall.
