Environmental Impacts of Ironstone Mining

The major outbreak of mine water into Saltburn Gill in 1999 turned the stream bright orange and smothered the downstream ecology, the issue wasn’t resolved until 2014/15 and required the Coal Authority to construct a £7m treatment plant.

A Masters student from the University of Hull has joined our project to report on the quality of the water in the becks within our project area and how they are being affected by smaller mine water discharges that still exist from other mines.

Here sampling is being carried out to capture and record the invertebrates found in the stream bed.

The types and numbers of invertebrates can be use determine the health of the watercourse, here a caseless caddisfly larvae can been seen which is a positive indicator.
