Chain of Custody

This form is filled out at sample collection and follows the sample through every person involved in the chain of possession until it reaches the laboratory. It includes information such as sample number, location where sample was taken, preservative used in each container, type and size of container for each sample (1 L glass, 500 mL amber glass, 250 mL plastic, 40 mL VOC vials, etc), dates and times of collection, type of sample (water, soil, wastewater, etc), and the name of person collecting the sample. Every time the sample changes possession, the person relinquishing the sample and the person receiving it must sign and date/time the Chain-of-Custody form.

NO SAMPLES WILL BE TESTED UNLESS THIS CHAIN OF CUSTODY FORM IS FILLED OUT, SIGNED & SHIPPED TO US WITH YOUR SAMPLES!
