Figure 2.

Prediction residuals between observed and predicted a) GW violation class, b) SW violation class, c) mean GW concentration, d) mean SW concentration, e) % of GW systems in violation, and f) % of SW systems in violation per catchment. Prediction Class Error: True Negatives are catchments without observed violations that are predicted to not be in violation, True Positives are catchments with observed violations that are predicted to be in violation, False Positive are catchments without observed violations that are predicted to be in violation. Conc. Residuals and % in Viol. Residuals: the amount of over (positive values) or under (negative values) prediction in mg/L or %, respectively.
