The TRRP 13 TRRP guidance for Review and Reporting of COC Concentration Data has been updated. Some of the major changes are:

• The term sample quantitation limit (SQL) has been changed to sample detection limit (SDL).
• Review qualifiers have been added to annotate data when the laboratory is not NELAC-accredited for the analyte, method, and/or matrix.
• A few bullets in the data usability summary (DUS) section have been added to require the DUS provide information on the NELAC-accreditation status of the laboratory at the time the data were generated.
• Detectability check sample results were added to the list of reported data on the laboratory review checklist (see R9).
