Box Plots

The boxplot shows the analyte bias and variability of the blind organic QA data. The plot also shows outliers and quartile ranges of the recovery data.

Extreme values have been "clipped" or removed from the plot and designated as such with a blue dot.

All data is provisional and may change if the OBSP deems necessary.

Note: If an analyte of interest is not seen in the method listing, there is no OBSP data available for that analyte
