The letter stated: Thank you for your letter dated March 9, 2020, requesting clarification on how holding times in the SW-846 Compendium, from sample collection to preparation and analysis, are interpreted, particularly for holding times greater than or equal to 7 days. While we do not agree that the holding time guidelines or associated sample preservation recommendations published in SW-846 are technically deficient, we understand and agree that inconsistent interpretations of how holding times are evaluated across EPA programs can create inadvertent problems or lead to confusion for sample collectors, laboratories, and data users. The SW-846 Methods Team will revise guidance related to holding times to be consistent with the interpretation above, and this interpretation will also be incorporated into Chapters 3 and 4 at the next available opportunity.
