Sampling Event Site

The siteId on a SamplingEvent connects the field sampling record to a specific site so that AnalyticalResults can be plotted in that site's concentration trend charts and compared against the ThresholdSetAssignments active for that site. When compliance reports are generated for a permit, all SamplingEvents for the relevant siteId are retrieved together to show the full monitoring history. Assigning the correct siteId at import time is critical — results attached to the wrong site will not be caught by that site's exceedance detection.
