SAMPLE DELIVERY GROUP CASE NARRATIVE

Client: FPM Remediations Job No: FC2733

Site: Joint Base Charleston AFB; N Charleston, SC Report Date: 3/6/2023 2:11:07 PM

On 02/16/2023, 15 Sample(s), 1 Trip Blank(s) and 0 Field Blank(s) were received at SGS North America Inc - Orlando. at a maximum corrected temperature of 2.2 C. Samples were intact and chemically preserved, unless noted below. A SGS North America Inc. - Orlando Job Number of FC2733 was assigned to the project.

Laboratory sample ID, client sample ID and dates of sample collection are detailed in the report’s Results Summary Section.

Specified quality control criteria were achieved for this job except as noted below. For more information, please refer to the analytical results and QC summary pages.

MS Volatiles By Method SW846 8260D Matrix: AQ Batch ID: V1A1749

Sample(s) FC3038-10MS, FC3038-10MSD were used as the QC samples indicated.

FC2733-11: Sample re-analyzed beyond hold time.

FC2733-14: Sample re-analyzed beyond hold time.

Matrix: AQ Batch ID: VI2823 Sample(s) FC2733-2MS, FC2733-2MSD were used as the QC samples indicated.

Matrix Spike /Matrix Spike Duplicate Recovery(s) for Benzene are outside control limits. Outside control limits due to high level in sample relative to spike amount.

FC2733-11: Confirmation run.

SGS North America Inc. - Orlando certifies that data reported for samples received, listed on the associated custody chain or analytical task order, were produced to specifications meeting the Quality System precision, accuracy and completeness objectives except as noted. Estimated non-standard method measurement uncertainty data is available on request, based on quality control bias and implicit for standard methods. Acceptable uncertainty requires tested parameter quality control data to meet method criteria.

SGS North America Inc.- Orlando is not responsible for data quality assumptions if partial reports are used and recommends that this report be used in its entirety.
