comprehensive site investigation and remediation objectives report

sample is possibly hot, this should be noted on the COC, to alert lab personnel in
handling the sample. COC forms are included in the appendices of reports, and
therefore shall have as professional an appearance as possible.
Samples will be packaged and transported in a manner that maintains the integrity of the
sample and permits the analysis to be performed within the prescribed holding time.
Prior to shipment, each sample container will be inspected for a label with the proper
sample identification code.
Samples will be either hand-delivered or shipped via overnight mail to the laboratory, or
picked-up by a laboratory representative. The COC forms will be sealed in a plastic bag
and transported inside the sample cooler. In addition, any shipping receipts will be
incorporated into the COC documentation. Samples will be packed in the cooler using
bubble-wrap packing materials. Any samples suspected of being highly contaminated
will additionally be sealed in Ziploc ® -type bag. The cooler will be taped closed using
custody seals provided by the laboratory to prevent tampering during transport. Upon
relinquishing the sample cooler, V3 field personnel will sign custody of the samples over
with the time and date at the bottom of the COC form. V3 will retain one copy of the
COC documentation and the laboratory will retain a second copy.
COC labels and forms provide immediate and necessary information for the processing
of samples by the laboratory, and establish historic documentation of the sampling
endeavor and tracking of samples, enabling defense of analytical data in a court of law.
The COC form serves as a link to the information provided on the sample labels, and
gives the lab overall information on the sample shipment (number of samples sent,
number of sampling containers, date, time, and other pertinent information). If
discrepancies are noted, these can be resolved early, when memories are still clear.
Visual observations or specific data on sampling locations or intervals may also be
helpful in future review of data.
