When collecting samples, what must be kept as part of the record?

When collecting samples, maintaining clear and organized records is essential for ensuring the integrity and traceability of the sampling process. A site sketch and unique identification codes serve as vital components in this documentation.

A site sketch provides a visual representation of the sampling location, which can be crucial for understanding environmental conditions, the layout of the area, and where specific samples were taken. This helps in future assessments, whether for analysis, monitoring, or compliance purposes. Unique identification codes are equally important as they allow for the precise tracking of samples throughout the testing and analysis process. They help differentiate between samples and provide a clear reference that can be linked directly back to the site and the conditions at the time of sample collection.

Collectively, these records ensure accuracy in data retrieval and analysis, facilitate communication among stakeholders, and adhere to regulatory standards, making them indispensable in the field of environmental monitoring and assessment.
