Further written evidence from the Chiltern
Society (HSR 81A)
I understand that the Transport Committee inquiry
into High Speed Rail is seeking evidence relating to the impact
on the environment.
Please find attached a link to a report on our website,
"Concerns arising from the Geology and Hydrology of the ground
underlying the High Speed (HS2) routes through the Chilterns".
The report was produced in November 2010 and shared with HS2 Limited.
It highlights the fractured nature of the chalk aquifer below
the Misbourne Valley, and the risks from tunnelling therein, particularly
the risk of polluting the aquifer, which feeds the Colne Valley,
which supplies 20% of London's water. Also the risk of losing
a globally rare chalk stream habitat.
The Report in full can be found at:
