Chain of Custody


The chain of custody portion of the collection cards should be filled out as described below:

  • If the person collecting the water sample will personally transport the sample to the Post Office (or other delivery service)
    • The collector should sign and date the first line labeled “Relinquished By” and then write Post Office (or other delivery service) on the “Received By” line.
    • Delivery services maintain their own tracking information so they do not need to sign the Chain of Custody form.

Example:

  • If the person collecting the water sample will NOT personally transport the sample to the Post Office (or other delivery service)
    • The collector should sign and date the first line labeled “Relinquished By”
    • The person they give the sample to should sign and date on the “Received By” line.
    • This procedure should be repeated until the sample is given to the Post Office.
