Purpose:
In addition to maintaining defensibility and traceability of the samples relinquished on the COC, labelling of sample jars allows the lab to confirm that the correct samples as listed on the COC were received. The labels must be legible and only the Sample ID is required – additional information such as project info, sampling date is not mandatory.
Tips for Labelling:
- Soil Jars – when writing the Sample ID on the lid and the label, make sure the ID’s match. The Sample ID is only required once on a soil jar
- Truncated ID’s are acceptable, so long as the truncated ID can be matched to a full ID on the COC
- Sometimes, less is more! Additional information such as sampling date or project info is not required, however if it is included on the label, it will be checked against the information on the COC
Process:
As samples are unpacked at Bureau Veritas Laboratories, they are reviewed against the COC to confirm all items have been received. If a label is missing, illegible or does not match, the lab contacts you for instruction on how to proceed.
Examples:
- The sampling date on the sample label doesn’t match the sampling date on the COC
- The sample ID written on the lid does not match the sample ID written on the labe
- There is no sample ID written on the label
- The sample ID has been damaged (ex. water from melted ice or condensation) and is illegible
