Mr. Niall Gleeson:

It is very unfortunate that we went back last year. The predominant issue is around trihalomethanes or THMs. We are trying to address it. I will ask Mr. Laffey to come in on this. It is a tricky issue to deal with and it is not for lack of trying. We have put systems into plants that have worked for a period and then stopped working. Mr. Laffey will give a bit of background to the THMs and how we deal with them. I want the committee to understand that we are trying to deal with this issue.
