Instructions for the External Chain of Custody Record/Field Test Data
Sheets for USEPA Methods TO-15 and 3C
At the request of several laboratories and consultants, the NJDEP will
allow combined External Chain of Custody Record/Field Test Data Sheets
to be utilized in place of separate sheets. These combined sheets must
be developed by the laboratory and contain all the information that is
currently required on both the NJDEP External Chain of Custody Record
and the NJDEP TO-15 Field Test Data Sheets. Single or multiple page External
Chain of Custody Record/Field Test Data Sheets are acceptable. The Laboratory
must also develop instructions for the sampler on what fields must be
filled in and how to complete the required fields on the form.
Approval from the NJDEP Office of Data Quality, Division of Remediation
Management and Response, is required prior to the implementation of the
combined External Chain of Custody Record/ Field Test Data Sheet by the
laboratory. The instructions must also be included for approval.
Upon approval from the Office of Data Quality, the integrated Chain
of Custody Record /Field Test Data Sheet must be added to in the Laboratory’s
Standard Operating Procedures for USEPA Method TO-15 and any other applicable
Laboratory Standard Operating Procedures. The revised Standard Operating
Procedures must be submitted to the NJDEP Office of Quality Assurance
for their records. |
An example of a combined External Chain of Custody Record/ Field
Test Data Sheet for USEPA Methods TO-15 and 3C is provided in the
document linked below. The one page example is courtesy of STL-Burlington
and Severn Trent Laboratories, Inc.
