### Analytical Approach

The ASR and supporting laboratories (PRL and MSLs) should work together to determine an appropriate analytical approach. In doing so, they should consider information from WCIT as well as the objectives of the monitoring (e.g., initial contaminant detection, determining if clean-up goals have been met) and data turnaround times.

When monitoring objectives necessitate rapid results, laboratories should consider what steps can be taken to reduce data turnaround times. Some potential actions may include:

Use of rapid methods Performing abbreviated QC Preparation of standards and calibration of instruments prior to sample arrival Reduced data review Data that is generated quickly, without performing full QC and/or full data review, should be qualified as "Preliminary Data Pending Confirmation," and should include appropriate data qualifiers. |
