Details

This map shows the rivers in Cornwall and Devon that are polluted by at least one metal, which includes cadmium, lead, zinc, copper, nickel, arsenic and iron, due to abandoned metal mines.

These rivers are marked in the colour purple.

In this part of the UK, the Water and Abandoned Metal Mines programme manages the Wheal Jane mine water treatment scheme to limit the amount of metals entering watercourses.

Wheal Jane is labelled and its approximate location is shown as a green circle.

Known mine water discharges are shown as a black cross inside a red circle.

Black triangles show abandoned mine waste sites that are causing serious environmental harm.
