Fig. 8. Bromide concentration in the model domain as a function of time. Results are for Simulation S-3. Maximum initial concentrations in the simulations are more than 10000 mg kg^–1; however, the color bar has been truncated at 40 mg kg^–1 to more clearly show the growth of the plume. In this figure, the simulated borehole LAWS-01 lies at x = 25 m, while Ports 1 through 4 are located at elevations of z = 76.5, 54, 44.5, and 22 m, respectively. The approximate locations of the ports are marked on the images as black circles.
