Figure 1: Contour plot of the concentration of gold in the pond 2 hours after the release of 48 µg/g ionic gold SRM 3121. After two hours, the gold had not yet dispersed significantly, and large amounts were still concentrated at the contamination site.
Figure 2: Contour plot of the concentration of gold in the pond 24 hours after the release of 48 µg/g ionic gold SRM 3121. After 24 hours, the gold appears to have dispersed relatively evenly among all points in the pond.
