To my awareness, there are only two studies for human health. The two were conducted, and the first one was in 2006, by Alberta Health and Wellness. They did a review of the health status of the community of Fort Chipewyan. In that review, they looked at not just cancers but the whole range of chronic diseases and so forth. In that study in 2006, they reported directly to the community the findings of the last study, and it reflected increased rates of diabetes, of renal disease, of hypertension, but they didn't find any increased rates of cancers at the time. However, with the continuing concerns being voiced by the community, by the physician, a more specific request was made to the Alberta Cancer Board to do a review of the first study.
They did, and this was done with the participation of the community and with the participation of federal and provincial jurisdiction, but the Alberta Cancer Board was the lead. It is the lead because it is the body that has the data on cancer for all Albertans in Alberta.
