Samples are considered "compromised" if the following conditions are observed upon sample receipt:
* Samples are received outside of temperature specification. * Samples are received broken or leaking. * Samples are received beyond holding time. * Samples are received without appropriate preservative. * Samples are received in inappropriate containers. * COC (if utilized) is not properly completed and signed. * COC (if utilized) does not match samples received. * Breakage of any Custody Seal. * Apparent tampering with cooler and/or samples. * VOA vials contain bubbles >1/4" (6mm). * Seepage of extraneous water or materials into samples. * Inadequate sample volume. * Illegible, impermanent, or non-unique sample labeling.
When "compromised" samples are received, it is documented on the Sample Receipt Information form or on a non-conformance report (NCM); and the client is contacted for instructions. If the client decides to proceed with the analysis, the report narrative will clearly indicate any/all or the above conditions and/or the data will be appropriately qualified.
