When field staff collect a groundwater sample, they assign a sample identifier that appears on the sample container, the chain-of-custody form, and ultimately the lab's analytical report. The sampleId stored on the SamplingEvent matches this label, enabling cross-reference between Piper's AnalyticalResults and the laboratory's chain-of-custody documentation. This traceability is required in many environmental compliance programs to demonstrate that reported results correspond to a specific, documented sample collection event.
