The Challenges Facing the HS2 Tunnels and Ventilation Shafts Construction Programme in the Chilterns.

We have been in consultation with the HS2 and the Environment Agency for some years about the potential damage that could be done to the chalk aquifer that supplies the water for the River Misbourne and River Chess. As part of the project HS2 plan to drill two tunnels and a number of ventilation/access shafts through the chalk, we are concerned that this work will damage the aquifer through pollution or blocking the migration route of the water that feeds our rivers. This could result in the loss of these rare iconic rivers and the habitat and wildlife they support. The Government identified this risk and in 2016 issued a financial indemnity worth up to £70 million to Affinity Water for the loss of their water source from the aquifer as a result of this work. HS2 have agreed to attend a meeting to give us a presentation on how they intend to mitigate the risks to our rivers.

The meeting is to be held on the 20th March at Chesham Town Hall at 7pm. It is open to the public. We are looking forward to an informative and orderly meeting.
