What is a chain of custody record?

A chain of custody record is critical in maintaining the integrity and accountability of samples throughout the testing process. This form documents the handling of a sample from the moment it is collected until it is reported on. It includes details such as who collected the sample, the time and date of collection, how the sample was stored, and who transferred it at each stage of the process. This rigorous documentation is essential to ensure that the results of the tests are valid and can be trusted, particularly in legal and regulatory contexts where the quality of drinking water is concerned.

Maintaining a proper chain of custody is crucial for upholding the reliability of the data collected, as any gaps or inconsistencies in the record could lead to questions about the authenticity of the sample handling process and the resulting test outcomes.
