  • Temperature blank or cooler environment must be documented; sample container should not be used.In the site-specific QAPP Contractor Addendum or ACQAP, specific information must be given on how the samples will be shipped to the laboratory, indicating how sample or information handling and custody information should be documented, such as in field notebooks and forms, and identifying the individual responsible for this (See Appendix B).

  • Temperature blank: A temperature blank is added to each sample cooler.

  • Temperature blank samples will accompany each cooler that contains samples with a temperature preservative requirement.

  • NOTE: The Temperature blank is not analyzed and it will not be combined with a sample that is intended to be analyzed.
