where it can be reviewed in conjunction with the sample result, associated regulatory criteria and any associated data usability implications. Soil/sediments, solids and tissues are reported on a dry weight basis unless otherwise noted. Definitions of all data qualifiers and acronyms used in this report are provided in the Glossary located at the back of the report. HOLD POLICY - For samples submitted on hold, Alpha's policy is to hold samples (with the exception of Air canisters) free of charge for 21 calendar days from the date the project is completed. After 21 calendar days, we will dispose of all samples submitted including those put on hold unless you have contacted your Alpha Project Manager and made arrangements for Alpha to continue to hold the samples. Air canisters will be disposed after 3 business days from the date the project is completed. Please contact Project Management at 800-624-9220 with any questions. Page 4 of 76

Serial_No:04172317:05 Project Name: Project Number: Lab Number: Report Date: WEST ORANGE DPW IN000380.09 L2317290 04/17/23 Case Narrative (continued) NJDEP Volatile Organics in Air Canisters were released from the laboratory on March 31, 2023. The canister certification results are provided as an addendum. Any Manual integrations that were performed on the sample(s), as well as on the associated quality control samples, are noted on the individual quantitation reports. A listing of all manual integrations performed and the integration code definitions are provided in the manual integration documentation section of the data package. Please note: Dilution analysis due to exceedance of the calibration range is not required for Ethanol or Isopropyl Alcohol. GC column and trap information utilized for the analysis of this sample delivery group is detailed below: Column Type: Restek RTX-1 Column Length: 60 Meters Internal diameter: 0.52 mm Film thickness: 1.00 um Trap 1: Entech Cold Trap - no packing material Trap 2: Entech Tenax - 20 cm packing material Gaseous calibration standards were utilized for system calibration and quality control standards associated with this sample delivery group. These standards were purchased from Linde (formerly Spectra Gases). Laboratory standard procedure for QC (i.e. method blanks, LCS) and sample analysis is to withdraw a 250 mL aliquot from the canister as the "1X" analysis. For some calibration levels and samples, subsequent dilutions will be performed as needed by decreasing aliquot volumes via the instrumentation, or by performing a dilution using a second canister. Make-up air is not routinely added to canisters prior to sample analysis. Page 5 of 76
