Regulatory Threshold Value

The thresholdValue is the core of a RegulatoryThreshold — it is the number that an AnalyticalResult's normalizedValue is measured against to determine whether an Exceedance occurred. It must be expressed in the same thresholdUnit used for normalized results so the comparison is valid. Getting the thresholdValue right is critical: entering a limit in the wrong unit (for example, mg/L when the standard is ug/L) would make the limit appear 1000 times higher or lower than intended, causing either missed exceedances or false alarms in your compliance monitoring program.
