Start with the governing documents
Identify the project purpose, matrix and jurisdiction. Include the actual permit or monitoring instructions where the results will support an agency submission.
Build the analyte and method list
Name each analyte, required method, reporting unit and reporting limit. Describe total or dissolved fractions and any preparation requirements. A broad category such as metals or organics does not define the complete target list.
Connect field and laboratory work
Identify sampling points, grab or composite approach, field measurements, timing and anticipated sample volume. Resolve bottles and preservation before collection.
Set reporting expectations
Provide project identifiers, sample naming conventions, recipients and required result formats. Final scheduling and delivery conditions are agreed around the actual scope.
