Continuing calibrations shall be compared to the initial calibration curve to determine<br />

that the analytical system is performing within acceptable range. QC sample results<br />

(LCSs , laboratory duplicates, <strong>and</strong> MS/MSD) shall be compared against stated<br />

acceptance criteria for accuracy <strong>and</strong> precision. QC data must meet acceptance levels<br />

prior to processing the analytical data. If QC st<strong>and</strong>ards are not met, the cause shall be<br />

determined. If the cause can be corrected without affecting the integrity of the analytical<br />

data, processing of the data shall proceed. If the resolution jeopardizes the integrity of<br />

the data, reanalysis shall be performed, if still within holding time. If the holding time<br />

will be exceeded, the decision regarding reanalysis will be made upon conferring with the<br />

Parsons PM or his designee.<br />

An administrative review will be performed by the laboratory project manager on each<br />

data deliverable package. The review will ensure that all requirements of the laboratory<br />

<strong>and</strong> the data deliverables have been met <strong>and</strong> are complete.<br />

A review of at least 10 percent of all data deliverable packages by a laboratory QA<br />

officer must take place prior to the administrative review <strong>and</strong> final release of the data<br />

deliverable. The data packages will be r<strong>and</strong>omly selected for review.<br />

8.2 LABORATORY DATA REPORTING FLAGS<br />

The following qualifiers must be used by the laboratory when reporting sample results.<br />

Qualifier Description<br />

J The analyte was positively identified, the quantitation is an estimation,<br />

<strong>and</strong>/or the analyte was positively identified but the associated<br />

numerical value is greater than the SQL but less than the PQL.<br />

U The analyte was analyzed for, but not detected. The associated<br />

numerical value is at or below the MDL.<br />

B The analyte was found in an associated blank, as well as in the sample.<br />

8.3 ASSESSMENT OF DATA USABILITY<br />

The Project Chemist will assess data usability <strong>and</strong> apply data qualifiers to the analytical<br />

results based on adherence to method protocols <strong>and</strong> laboratory-specific QA/QC limits.<br />

8.3.1 Data Usability Assessment<br />

The laboratory deliverable will include the following information:<br />

• Case narratives;<br />

• Chain-of-custody forms;<br />

• Summary of results by sample;<br />

• Holding times;<br />

• Sample temperatures during shipping <strong>and</strong> storage;<br />

• Summary of QC results (method blanks, equipment blanks, laboratory duplicates,<br />

LCS, MS/MSD, etc.);<br />
