All testing was performed according to our laboratory's quality assurance program and met the requirements of the TNI standards except as noted in the case narrative report. Any testing not included in the lab's accreditation is identified on a Non-Certified Analytes report. All results are intended to be considered in their entirety. ALS Environmental is not responsible for use of less than the complete report. Results apply only to the individual samples submitted to the lab for analysis, as listed in the report. The measurement uncertainty of the results included in this report is within that expected when using the prescribed method(s),.and represented by Laboratory Control Sample control limits. Any events, such as QC failures or Holding Time exceedances, which may add to the uncertainty are explained in the report narrative or are flagged with qualifiers. The flags are explained in the Report Qualifiers and Definitions page of this report. Please contact me if you have any questions. My extension is 7472. You may also contact me via email at Janice.Jaeger@alsgiobal.com.

This report contains .analytical results for samples for the Tier level IV requested by the client. Sample Receigto. Seven water samples were received for analysis at ALS Environmental on 06/11/2022.Any discrepancies upon initial sample inspection are annotated on the sample receipt and preservation form included within this report. The samples were stored at minimum in accordance with the analytical method requirements. One or more samples were subcontracted to another laboratory for testing.The certified analytical report from the subcontractor has been,included in its entirety at the end of this report and includes the name and address of the subcontracted laboratory. Semivolatiles by GC/MS: Method 8270D, 768125:The lower control limit for the spike,recovery of the Duplicate LaboratoryControl Sample(LCSD)was exceeded for one or more analyte.The Laboratory Control Sample(LCS)passed limits.There were no detections of the analyte (s) in the associated field samples.The analytes affected are flagged in the LCS Summary. Metals: No significant anomalies were noted with this analysis. General Chemistry;, li No significant anomalies were noted with this analysis. Subcontracted Analytical Parameters: No significant anomalies were noted with this analysis. . Volatiles by GC/MS: Method 8260C, 06/16/2022:The upper control limit was exceeded for one or more analytes in the Continuing Calibration Verification(CCV). The field samples analyzed in this sequence did not contain the analyte(s) in question above the Method Reporting Limit(MRL). Since the exceedance equates to a potential high bias,the data quality was not significantly affected and no further corrective action was taken. Method 8260C, 06/16/2022:The lower control limit was exceeded for one or more analytes in the Continuing Calibration Verification (CCV). Since there were no detections of the analyte(s)above the MRL in the associated field samples,the quantitation is not affected. The data quality was not significantly affected and no further corrective action was taken. Method 8260C, 06/16/2022:The upper control criterion was exceeded for one or more analytes in the Laboratory Control Sample (LCS). There were no detections of the analyte(s)above the MRL in the associated field samples. The error associated with elevated recovery.equates to a high.bias. The sample data is not significantly affected. No further corrective action was appropriate. � r F-_1 f Approved by Date 07/12/2022 II Page 3 of 131 ALS Enuiranmental Sample Receipt Inf • • ALS Environmental—Rochester Laboratory 1565 Jefferson Road, Building 300, Suite 360, Rochester, NY 14623 Phone (585) 288-5380 Fax (585) 288-8475 www.aisgiobal.com RIGHT SOLUTIONS I RIGHT PARTNER Page 4 of 131 Client: Parsons Service Request:R2205340 Project: ILI-Region 1 Southold LF/452148.01000 SAMPLE CROSS-REFERENCE SAMPLE# CLIENT SAMPLE ID DATE TIME } R2205340-001 1-SUF-028-002-01 6/9/2022 1300 R2205340-002 1-SUF-028-002-02 6/9/2022 1410 R2205340-003 1-SUF-028-002-03 6/9/2022 1700 R2205340-004 1-SUF-028-002-04 6/9/2022 1715 R2205340-005 1-S U F-028-002-05 6/9/2022 1515 R2205340-006 1-S U F-028-002-06 6/9/2022 1515 R2205340-007 1-S U F-028-002-07 6/9/2022 r_I i ! 1 1J ' i t Printed 7/12/2022 9:29:26 AM Page 5 of 131 Sample Summary CHAIN-OF-CUSTODY J Analytical Request Document Section A Laboratory information Section S Client Information COC 1-SUF-028-002 Lab Name: Aly Company: Parsons Project Attention: Janice Jaeger Attention: Sara Welshaupt flame: III - Region 1 1565 Jefferson Road,Bldg 300,Suite 360 301 Plainfield Road,Suite 350 Proms Address: Rochester NY 14623 Address: Svracuse,NY 13212 Sft' Southold IF Phone: 585-288-5380 Phone: 315-SS2.3681 Num ; 1452148.01000 presernlae, er@al lobal.com Email: Sara.Weishaupt@parsons.com vat 21 z 3 t3-1 01eron ): Email: � ke9 s9 o t o o a s o 0 1 0 Section C Deliverable Requirements Purchase Order No: Report To: Sera.Weisheupt@parsons.com TAT- 10 Da Copy To: Lorralne.Weber@parsons.00m;Laura.Dramons.eom y chenberg@par Ma anne.Kosdewicz@ rsons.com; Heather.f;etUg@parsons.com jSectlon D Additional Information A Deliverables: Level 2,CAT B Report,NYSDEC EQUIS EDD I 9 Start I End Sample Sample Semple Sample a of 9 1 Depth Depth Reid Sample ID Data Time Matrix Type Cont Location ID (R R MUST BE UNIQUE Isomffiffiftis ? 3 2 21211 1 3 1 1 2 1 1-SUF-028- 131 l 1-SUF-028-002-01 �14� x WG N 18 x x x x x x x x x x 2 1-SUF-028- re34 l3I 1-SUF-028-002-02 IgLaX 1410 WG N 18 x x x x x x x x x x x 3 1-SUF-028- Mud s I i %12 1-SUF-028-002-03 9 WG N 18 x k x x x x x x x x x 4 1-SUF-028- M W l1'D 1 141 1-SUF-028-002-04 818 1-115 WG N 18 x x x x x x x x x x x 5 Feld Qualityi-SUF-028-002-05 tql?ru. 16(5 WO.

All results are intended to be considered in their entirety. ALS Environmental is not responsible for use of less than the complete report. Results apply only to the individual samples submitted.to the lab for analysis, as listed in the report. The measurement uncertainty of the results included in this report is within that expected when using the prescribed method(s), and represented by Laboratory Control Sample control limits. Any events, such as QC failures or Holding Time exceedances, which may add to the uncertainty are explained in the report narrative or,are flagged with qualifiers. The flags are explained in the Report Qualifiers and Definitions page of this report. , I Please contact me if you have any questions. My extension is 3260.

This report contains analytical results for samples for the Tier level II requested by the client. Sample Receipt: Six water samples were received for analysis at ALS Environmental on 06/11/2022.Any discrepancies upon initial sample inspection are annotated on the sample receipt and preservation form included within this report. The samples were stored at minimum in accordance with the analytical method requirements. Organic LC: Method PFC/537M, 06/22/2022:The upper control criterion was exceeded for Perfluoroheptane sulfonic acid (PFHpS)in Continuing Calibration Verification(CCV).The field samples analyzed in this sequence did not contain the analyte in question. Since the apparent problem indicated a potential high bias,the data quality was not affected. No further corrective action was required. Method PFC/537M, 06/22/2022:The upper control criterion was exceeded for 13C2=6:2 FTS and 13C2-8:2 FTS in sample s1- SUF-028-002-03.Assuming the associated native analytes performed similar to the labeled analog,the effect on the reported results was minimal.The sample was reran and the results confirmed, no further corrective action was needed.
