We have been conducting studies in the area related to contamination and we've done toxicological work in terms of sediment toxicology in other areas.
Regarding the monitoring station that you're referring to, the position of that monitoring station before Wood Buffalo National Park was because it was entering a federal national park and we were concerned about the types of water quality that were going into that particular area. That is one of the headwater regions into the Peace-Athabasca Delta. From our perspective, we are getting baseline information in terms of fundamental water quality parameters going into that system, but we do rely on Alberta Environment and other research efforts that are going on, both within the region and in related areas, to obtain more information on many of the constituents you've talked about.
