ATTACHMENT 8 - Technical Exhibit E - Example Chain of Custody Form.pdf

This document is a Chain of Custody form (Attachment 8 - Technical Exhibit F) used for tracking and documenting sample collection and analysis. The form provides a structured template for recording critical information about scientific or environmental samples, including project details, sample locations, collection dates and times, sample identification, number of containers, and preservation status. The form includes fields for tracking the sample's chain of custody through multiple handoffs, with spaces for signatures, dates, and times when samples are transferred between personnel, ensuring a comprehensive and auditable record of sample management.

The form contains columns for logging key sample metadata such as date, time, sample location, sample identification/station, number of containers, preservative status, and requested types of analyses. A dedicated shaded area is reserved for laboratory use to record additional check-in details like sample DO (dissolved oxygen), pH, conductivity/salinity, chlorine levels, and appearance. The bottom of the form includes multiple sections for documenting who sampled the specimens, when they were collected, and the subsequent chain of custody with signatures and timestamps for each transfer of the samples.
