The dataset contains the results of analyses of surface water samples collected by AGS in the summer of 1999. Three lakes, three creeks, one stream and two rivers were sampled as part of a water sampling program carried out by AGS in the Athabasca Oil Sands in-situ area of Alberta. This area extends from approximately 55.34 degrees north latitude to 55.96 degrees north latitude, and 110.5 degrees west longitude to 111.8 degrees west longitude. The datum is NAD83. The dataset contains information on laboratory measured pH and conductivity, major, minor and trace element concentrations, as well as stable isotope ratio values of oxygen and hydrogen. AGS staff collected the samples using a discrete sampling method. The sample bottle was dipped into the surface water body and partially filled with water, rinsed and the water was discarded. The bottle was then filled and capped. The sample was subsequently filtered on site using a 0.45 micron filter. A sample was acidified for minor and trace-element analysis. Separate samples were collected for stable-isotope analysis. The major, minor and trace-element concentrations were determined by Norwest Labs of Edmonton. The stable isotope values were determined by the University of Calgary stable-isotope lab. The data are as they were received from the laboratories. A change in focus for the second year of the program meant much of the data were not included in the final report, and so were not interpreted to any extent. The data have not been processed or modified.
