Sarah Green (Chesham and Amersham) (LD)
It is a pleasure to serve under your chairmanship, Mr Mundell. My constituents have made no secret of how important this issue is to them. That is why it does not surprise me that so many residents of Chesham and Amersham put their name to this petition. I join their plea to stop HS2 and put on record my opposition to it.
I have had hundreds of emails about this debate, as well as various emails and meetings in which specific concerns have been raised about the construction now taking place. I could fill the time available to us by listing those concerns, but I will resist. What many locally hoped would not happen is now happening. As far as they are concerned, it is happening to them, which is why it does not surprise me that the highest number of signatories to the petition are from Chesham and Amersham.
From the daily correspondence that I receive on this issue, what strikes me is the persistent lack of trust in HS2 Ltd, which is openly acknowledged by the team at HS2. They have assured me more than once that they are working hard to address that with the local community, but we have been here before. Five years ago, in December 2016, a special report by a House of Lords Select Committee highlighted its concerns about community engagement. Three years later, the Oakervee review said something similar. I therefore ask the Minister whether he is satisfied that he is seeing enough improvement in this area from HS2 Ltd. The lack of trust is inevitably compounded by the day-to-day reality of the largest infrastructure project in Europe happening on our doorstep. Let us not forget that those affected have years of this to look forward to—a decade of debilitating disruption.
I will finish by discussing the real fears for the aquifer and water supply. The Minister will be aware of concerns about the use of bentonite. Indeed, my predecessor asked in July 2018 whether there was a plan to use bentonite under pressure when tunnelling under the Chilterns. The reply she received from the Minister at the time was that
“Bentonite will be used in the construction of the diaphragm walls for the 5 intermediate shafts. Prior to the use of bentonite in these locations the construction methodology dictates that the ground surrounding the diaphragm walls will be grouted, therefore sealing and protecting the ground water from the bentonite.”
However, the Minister will know that it has come to light that, during diaphragm wall excavation at the Chalfont St Peter vent shaft late last year, there was a significant loss of bentonite. There is a clear correlation between that loss and changes in water quality in the area. HS2 Ltd chose not to share this information with the community; we know about it only because of a freedom of information request that was submitted to the Environment Agency.
The last thing that local campaigners want to say is, “I told you so”, so I ask the Minister whether he will come and hear from residents, whose fears for our water supply are real and have not been allayed by the assurances that they have received to date. Given the repeated calls for increased transparency and openness over the years, I ask the Minister to come and meet some of my constituents and decide for himself whether HS2 Ltd’s commitment to openness and transparency is being fulfilled.
