Comparison of Ln Measured PCE Concentration (ug/L) with Ln Model Estimated PCE Concentration (ug/L): Manual Method. This figure depicts the relationship between measured PCE concentration and model estimated PCE concentration using the manual method. There was a moderate level of correlation between measured and modeled PCE concentrations using the manual method (ρ = 0.54, p < 0.001) but the magnitude of correlation was lower than that of the automated method.
