I think the guidelines are working. They're comparable to international guidelines and standards. They are designed to be protective of health, and we do certainly follow up on all the new science in terms of health impacts and levels of exposure across the country, and we work closely with the provinces to get that information.
Where we see the biggest challenge, as I mentioned during the presentation, is the small community water supplies where you actually don't necessarily have the treatment technology, the operators, the funding, or the source water protection you need to provide the same level of drinking water quality you would in a larger town. This is an area where Health Canada is trying to focus very strongly in terms of helping smaller communities improve their drinking water safety, and that would include working with first nations groups.
