What does the “verify” triangle in the graph legend items signify?
The verify triangle indicates that the previous sample (or one of the previous 2 samples for 1 of 2, or both of the previous samples in 2 of 2 resampling mode) went over the limit line. This means that the data point in question is being used to verify the preceding value. If the preceding exceedance is verified by the current point, then the graph title will include “verified exceedance.” As new data comes in on the well/constituents, if it continues to exceed the limit, the sample concentrations will continue to have triangle data markers until the concentration drops below the limit for the required number of verifications.
