With regard to lead in the water, you're absolutely right, and I completely agree that there is no safe level of lead in our drinking water. I support local authorities, local councils, in their testing of water. I think there is a co-relation the member is wanting to draw with some of the products that are used by plumbers that may then lead to leaching of lead into drinking-water supplies. I have to say that some of the information that I have seen with regard to resting doesn't demonstrate that, doesn't prove that.
