Define the routine program
List locations, matrices, methods, analytes, expected sample counts and cadence. Identify which requirements apply to every round and which are event dependent.
Keep bottle and order records consistent
Use stable sample IDs, standard bottle sets and the current scope. Changes in locations or parameters should reach both the field team and the laboratory.
Agree operational arrangements
Provide anticipated dates, reporting recipients and project formats. Scheduling and delivery requirements are agreed for the actual program; this page does not promise unconfirmed receiving hours or turnaround.
Review revisions
A changed permit, treatment process, analyte list or reporting limit can require a new scope review before the next collection round.
