Figure 4

Co-produced water reservoir downwind plume mixing plot.

Background air is shown as a red dot and the downwind plume samples are the black dots. The blue line is the line of best fit for the mixing model (equation (4)) and the 90% confidence interval bands are shown in orange. Source intercept determined for the mixing model is −50.8‰ (90% CI, −55.7‰ to −45.8‰).
