Each AnalyticalMethod has a methodId (the official method designation such as "8260B" or "200.8"), an agency (the body that published it, like "EPA" or "ASTM"), and an analyteGroup indicating which class of chemicals the method covers. When an AnalyticalResult is linked to an AnalyticalMethod, regulators can verify that the correct analytical procedure was applied. Recording the method is often a regulatory requirement in quarterly monitoring reports and site characterization documents.
