2.44 Data Validation and Data Assessment Corrective Action<br />

Corrective actions may be required for field activities and analytical work based on the outcome of data<br />

validation and data assessment activities as well as site audits. Corrective actions may include<br />

resampling and reanalysis, especially when critical sample results are rejected during the data validation<br />

process.<br />

The following situations require corrective action based on data validation and data assessment:<br />

Critical sample results are rejected<br />

Background sample data are rejected<br />

Excessive blank contamination, rendering data to be questionable<br />

QC criteria exceeding allowable limits<br />

Results with extremely high detection limits<br />

Data completeness not meeting project requirements (90 percent for field data, 95 percent for<br />

analytical data)<br />

Proper procedures not implemented in the field or in the laboratory<br />

Data is not legally defensible<br />

All corrective actions of this type will be documented by the Data Validator(s) and Data Officer or<br />

designee and approved by the PM.<br />

2.45 Laboratory Corrective Action<br />

Corrective action in the laboratory may occur prior to, during, and/or after analyses. The laboratory must<br />

perform corrective actions on all out-of-control events (e.g., initial calibration, continuing calibration,<br />

verification, blanks, spikes, etc.) immediately and must bring analytical processes into control prior to<br />

proceeding with the analyses. Corrective action reports must be prepared for each out-of-control event,<br />

and must document the actions taken, the resolution of the problem, and the return to analytical control.<br />

If corrective action does not rectify the situation, the laboratory will contact the PM for resolution.<br />

14.1.3 Sample Control Nonconformance<br />

The following conditions constitute a sample control nonconformance, which typically occurs prior to<br />

analyses:<br />

Incorrect/incomplete or missing C-O-C<br />

Custody seal not intact<br />

Broken sample container<br />

Insufficient sample volume<br />
