Sampling Event Sample Date

The sampleDate is one of the most important fields on a SamplingEvent because it controls where results appear on concentration trend charts and how they are grouped in regulatory reports. All AnalyticalResults linked through the samplingEventId inherit this date as the collection timestamp. Permit reporting periods are typically defined by date ranges, so an incorrect sampleDate can cause results to fall outside the reporting window they belong to. Always confirm sampleDate matches the chain-of-custody collection date before committing an ImportBatch.
