About this file
This is an Enthalpy Analytical Test Report documenting laboratory analysis results for environmental samples. The report contains EPA Method 1633 compliant testing for Per- and Polyfluoroalkyl Substances (PFAS) in two sample matrices: soils/solids following Table B-24 parameters and non-potable water following DOD QSM Table B-24 specifications. The analysis identifies compounds including PFBA (375-22-4) with quantified results reported in ng/g for soil samples (designated C-1 and C-2). The report includes comprehensive quality control documentation, including blanks, controls, sample custody records, chain of custody documentation, and shipping records spanning multiple pages. Results are organized with case narratives, general reporting notes, summary tables, detailed analytical results, and QC data validation.
The test report appears to be supporting documentation for environmental site assessment or remediation activities, possibly related to the Navy SOF Operations Building Addition and Renovation project at NAS Oceana Dam Neck Annex in Virginia Beach. The analytical work demonstrates compliance with federal environmental testing standards and includes full traceability documentation. However, this document functions as a technical appendix or supporting reference material rather than a primary solicitation document, and does not specify response dates, pricing terms, or contract-specific requirements.

Primary b: Peak starts or ends on the baseline t: Peak starts or ends at the start or end of the trace Code d: Peak starts or ends on a drop line M: The peak start or end point was manually altered v: peak starts or ends on a valley -: The peak was manually deleted s: Peak is a shoulder on another peak X: Point manually excluded from the calibration curve !: Flagged peak l: The response would either give a negative concentration or the calibration equation is not solvable for the given response (indeterminate flag)
Secondary n: Peak was not integrated by the software Code c: Peak was integrated incorrectly by the software r: The wrong peak was integrated by the software creating a false positive result based on retention time, qualifier ratios, or other criteria

Primary b: Peak starts or ends on the baseline t: Peak starts or ends at the start or end of the trace Code d: Peak starts or ends on a drop line M: The peak start or end point was manually altered v: peak starts or ends on a valley -: The peak was manually deleted s: Peak is a shoulder on another peak X: Point manually excluded from the calibration curve !: Flagged peak l: The response would either give a negative concentration or the calibration equation is not solvable for the given response (indeterminate flag)
Secondary n: Peak was not integrated by the software Code c: Peak was integrated incorrectly by the software r: The wrong peak was integrated by the software creating a false positive result based on retention time, qualifier ratios, or other criteria
