Figure 7: Chlorine demand (dark shading) and computed average pit propagation rates (light shading) based on  mV (versus Ag-AgCl). No propagation rate is shown for tests in which was not observed. Conditions are grouped by respective changes to the control water quality (ANOM, Bozonated NOM, Csodium acetate/d-glucose), and the control tests are shown with hash marks in each grouping. S and L indicate small- and large-scale tests, respectively.
