Mr. Speaker, it is a pertinent question. Whatever we do, the guidelines we put forth have to be based on good science. Science would give us the basis upon which we could have guidelines that were reasonable, that were safe in terms of health care aspects and guidelines that were doable. Sometimes we set standards that are not attainable. We need to have attainable standards that are safe for the public and that are imminently doable, and we can do it.
A lot of the science has already been done. One very interesting thing is that a number of new water achievement capabilities have been discovered around the world. We need to extract the best information from around the world, and on a case by case basis utilize water purification mechanisms appropriate for given communities.
In my area of Victoria sewage is dumped out after only primary treatment. To my knowledge, that is not much of a problem because of where the water is and the velocity of the tides. I am sure that it would give comfort to people in Victoria to have a secondary water treatment system where we could remove a number of other substances that are bioaccumulating in our environment, the likes and consequences of which we do not know at this point in time. The bottom line is base the guidelines on good science.
