Thank you very much for calling me to speak in this debate, and thanks very much to the petitioners for bringing these important points to our attention. I'm not actually on this committee, so I wasn't present to hear some of these discussions in detail, but I have certainly been approached by many people in my constituency and by different petitioners.

In a fairly short contribution, what I'd really like to say is that I feel that the depth of concern is there and that people have not been reassured by the responses that have come from NRW and that have come from other agencies. It does seem to me very important that we do absolutely the maximum we can to ensure we know what is in the sediment that is being dumped so close to us here in Cardiff. So, I would certainly support the recommendation of the Petitions Committee that there should be further samples taken, and I would speak in support as well of Mike Hedges's contribution, because I think that it is our utmost duty to keep our population safe and that we should do all we possibly can to ensure that everything we can do is done.

I do think that the independent academic research would be a way forward. I certainly accept what David Melding has said—that at some point you have to have a trust in what agencies may say that are giving genuine scientific, independent views—but I don't really think we're actually at that stage from what I've heard. I think there is a clear case for having further samples taken, and I hope that that will happen.
