Chain of Custody
A Chain of Custody (COC) is a legal document and is required to be submitted with all samples. This document verifies the condition of the samples, provides specific instructions for analyses requested, and most importantly, establishes a record of control and transfer of the samples.
PDF and Excel versions of the OEC COC are available for download below. Please contact your Project Manager if you need assistance with this document.
