Thank you, Mr. Chairman. My other question has to do with monitoring and trying to evaluate where some of these cancer-causing components could come from. My concern with the water question in McPherson is with regard to traces within the water and also the usage of chlorine over the last number of years; the possible connection of that to cancer. This is something that the community should look at with regard to ... You say you're in charge of health, environment and monitoring. As a department, do you evaluate water or do you just leave that up to the Department of Public Works? When it becomes a health issue, do you guys seriously look at the possible effects it may have?
