Lord Berkeley (Lab)

My Lords, I support Amendment 147 on chalk streams. I was brought up in the Chilterns and I have been studying some of the streams there for a very long time. As other noble Lords have said, they are the most wonderful bits of the countryside, with clear water—which comes and goes, but it is usually there. I became involved in this when I opposed some of the work that HS2 was doing in trying to drill a tunnel underneath the chalk stream near Amersham. The Chiltern Society, which led the opposition, was very keen that HS2 put some boreholes down to check what the ground was like and make sure that drilling a tunnel close to underneath a chalk stream would not have any adverse effect on it. Of course, HS2, being the rather arrogant organisation it often was, said, “It is not necessary. We know everything that is going to happen there and it is all planned for. We won’t have any special protection apart from the normal tunnel construction”. Of course, HS2 was wrong and when the tunnel got to underneath the stream just west of Amersham, contamination started, water levels dropped and there was a lack of water supply in some places. It said, “Oh dear”, and did nothing about it. It is all right now—I think it has all been solved—but my point is that if this amendment had been on the statute book 10 years ago, the local people and the experts would have had much more credibility in attacking a government organisation trying to build a tunnel than has happened so far. There are probably many other examples and noble Lords have mentioned some, but it is important that we map these chalk streams and make sure that they are looked after, because they are very special.
