The Coal Authority is working with the Environment Agency to clean up pollution from abandoned mines.
The River Nent is the second worst metal polluted river in England. The discharge from the Haggs Level is one of the major mine water discharges into the River Nent. Others include the Caplecleugh and Rampgill Levels further upstream and the Nent Force Level in Alston.
As a consequence, the aquatic life in the River Nent is severely damaged by the high metal concentrations.
To address the pollution, we are developing a proposal to build a mine water treatment scheme to clean up the polluted water discharging from the Haggs Level in Nentsberry before it reaches the River Nent.
This will improve the water quality within the watercourse and improve the environment for wildlife and people.
