Programmatic Sampling and Analysis Plan Project Number:60657245 Table 2.3 —Quality Assurance Objectives QC Sample and/or Activity Data Quality Indicators Use to Assess Measurement DQIs Measurement Performance Criteria Performance Precision—Laboratory See laboratory limits MS/MSDs and/or LCS/LCSD For Laboratory Duplicates the following criteria will be Laboratory Duplicates used: • If the parent sample and duplicate values are >5xRL, then <20% RPD for water samples(<35%soil and other matrices). • If the parent sample or duplicate sample value is <5xRL,then absolute difference is<1 xRL for water samples <2xRL for soil and other matrices). See analytical method and/or DoD QSM 5.3 Calibration—Initial and Continuing Precision—Field For Field Duplicates the following criteria will be used: Field Duplicates • If the parent sample and duplicate values are >5xRL, then <30% RPD for water samples(<50%soil and other matrices). • If the parent sample or duplicate sample value is <5xRL,then absolute difference is<2xRL for water samples <3xRL for soil and other matrices).

The process through which data will be accepted or rejected will be based on specific data verification and validation criteria. AECOM personnel experienced with sampling and analytical protocols and procedures will perform the data validation in accordance with the established criteria and the intended use of the data. Stage 213 data validation will be performed on laboratory data packages. This will include review of chain of custody forms, laboratory receipt checklist, sample related QC data and QC acceptance criteria linked to field samples, requested spike analytes as appropriate (LCS, matrix spikes), QC sample frequency, initial calibration summaries, initial and continuing calibration verification summaries, instrument performance check summaries, and preparation logs. Data validation qualifiers will be applied as necessary in accordance with Table B-15 of DoD QSM version 5.3, or the associated applicable criteria. AECOM 7
