Quality Control Measures Describe sample-handling procedures including sample preservation and transportation: After collection, samples were placed in laboratory-supplied containers and labeled. The samples were then placed in an ice filled cooler for preservation and transported to the laboratory for applicable analysis. Describe decontamination procedures used; To reduce the risk of cross contamination, new disposable latex gloves were worn during each sample collection. The decontamination procedures outlined below are used for field equipment (e.g., hand augers, split spoon sampling device, trowels) that come into direct contact with the material being sampled and that is used more than once at a particular site. All sampling equipment was decontaminated between each sample by using alconox and distilled water. Describe time and date samples were collected and date submitted to lab; Samples were collected at the site between 1520 and 1630 on October 13, 2020. The samples were logged into the laboratory October 16, 2020 (see laboratory reports and associated Chain-of-Custody Forms in Appendix C). Describe samples collected for quality control purposes (e.g. duplicates, field blanks, trip blanks, etc.). Include methods used to obtain these samples and analytical parameters; No quality control samples were utilized for this assessment. Describe how results of quality control samples may have affected your interpretation of soil, groundwater or surface water sample results; No quality control samples were utilized for this assessment. E. Investigation Results Describe results of Site Sensitivity Evaluation (SSE), (if SSE was not conducted, explain why not); A surface water body is located approximately 1,800 feet to the northeast of the subject property and a water well located approximately 1,500 feet to the west. In addition, underground utilities such as storm sewer, sanitary sewer, water lines, etc., are typically considered potential vapor collection points and conduits for vapor/contamination travel, which are located near Old Statesville Road and WT Harris Boulevard.

Therefore, not all TICs are identified and quantitated using individual standards. TIC listings are prepared utilizing a computerized library search routine of electron impact mass spectral data and evaluation of the relevant data by a mass spectral data specialist. Quantitation isaccomplished by relative peak area of the TIC compared to that of the nearest internal standard from the total ion chromatogram. TICs are identified and quantitated only if the peak area is 10% or more of that of the nearest internal standard. 1 Cp 2Tc 3Ss 4Cn 5Sr 6Qc 7Gl 8Al 9Sc ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Excel Civil & Environmental Associates 2020102 L1274449 10/27/20 14:56 32 of 74 ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Excel Civil & Environmental Associates 2020102 L1274449 10/27/20 17:45 32 of 74 ONE LAB.

NATIONWIDE.GLOSSARY OF TERMS Guide to Reading and Understanding Your Laboratory Report The information below is designed to better explain the various terms used in your report of analytical results from the Laboratory. This is not intended as a comprehensive explanation, and if you have additional questions please contact your project representative. Results Disclaimer - Information that may be provided by the customer, and contained within this report, include Permit Limits, Project Name, Sample ID, Sample Matrix, Sample Preservation, Field Blanks, Field Spikes, Field Duplicates, On-Site Data, Sampling Collection Dates/Times, and Sampling Location. Results relate to the accuracy of this information provided, and as the samples are received. Abbreviations and Definitions (dry)Results are reported based on the dry weight of the sample. [this will only be present on a dry report basis for soils]. MDL Method Detection Limit. MDL (dry)Method Detection Limit. RDL Reported Detection Limit. RDL (dry)Reported Detection Limit. Rec.Recovery. RT Retention Time. RPD Relative Percent Difference. SDG Sample Delivery Group. (S) Surrogate (Surrogate Standard) - Analytes added to every blank, sample, Laboratory Control Sample/Duplicate and Matrix Spike/Duplicate; used to evaluate analytical efficiency by measuring recovery. Surrogates are not expected to be detected in all environmental media. U Not detected at the Reporting Limit (or MDL where applicable). Analyte The name of the particular compound or analysis performed. Some Analyses and Methods will have multiple analytes reported. Dilution If the sample matrix contains an interfering material, the sample preparation volume or weight values differ from the standard, or if concentrations of analytes in the sample are higher than the highest limit of concentration that the laboratory can accurately report, the sample may be diluted for analysis. If a value different than 1 is used in this field, the result reported has already been corrected for this factor. Limits These are the target % recovery ranges or % difference value that the laboratory has historically determined as normal for the method and analyte being reported. Successful QC Sample analysis will target all analytes recovered or duplicated within these ranges. Original Sample The non-spiked sample in the prep batch used to determine the Relative Percent Difference (RPD) from a quality control sample. The Original Sample may not be included within the reported SDG. Qualifier This column provides a letter and/or number designation that corresponds to additional information concerning the result reported. If a Qualifier is present, a definition per Qualifier is provided within the Glossary and Definitions page and potentially a discussion of possible implications of the Qualifier in the Case Narrative if applicable. Result The actual analytical final result (corrected for any sample specific characteristics) reported for your sample. If there was no measurable result returned for a specific analyte, the result in this column may state “ND” (Not Detected) or “BDL” (Below Detectable Levels). The information in the results column should always be accompanied by either an MDL (Method Detection Limit) or RDL (Reporting Detection Limit) that defines the lowest value that the laboratory could detect or report for this analyte. Uncertainty (Radiochemistry)Confidence level of 2 sigma. Case Narrative (Cn) A brief discussion about the included sample results, including a discussion of any non-conformances to protocol observed either at sample receipt by the laboratory from the field or during the analytical process. If present, there will be a section in the Case Narrative to discuss the meaning of any data qualifiers used in the report. Quality Control Summary (Qc) This section of the report includes the results of the laboratory quality control analyses required by procedure or analytical methods to assist in evaluating the validity of the results reported for your samples. These analyses are not being performed on your samples typically, but on laboratory generated material. Sample Chain of Custody (Sc) This is the document created in the field when your samples were initially collected. This is used to verify the time and date of collection, the person collecting the samples, and the analyses that the laboratory is requested to perform. This chain of custody also documents all persons (excluding commercial shippers) that have had control or possession of the samples from the time of collection until delivery to the laboratory for analysis. Sample Results (Sr) This section of your report will provide the results of all testing performed on your samples. These results are provided by sample ID and are separated by the analyses performed on each sample. The header line of each analysis section for each sample will provide the name and method number for the analysis reported. Sample Summary (Ss)This section of the Analytical Report defines the specific analyses performed for each sample ID, including the dates and times of preparation and/or analysis. Qualifier Description B The same analyte is found in the associated blank. C4 The reported concentration is an estimate. The continuing calibration standard associated with this data responded low. Data is likely to show a low bias concerning the result. J The identification of the analyte is acceptable; the reported value is an estimate. J0 J0: The identification of the analyte is acceptable, but the reported concentration is an estimate. The calibration met method criteria. J3 The associated batch QC was outside the established quality control range for precision. J4 The associated batch QC was outside the established quality control range for accuracy. 1 Cp 2Tc 3Ss 4Cn 5Sr 6Qc 7Gl 8Al 9Sc ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Excel Civil & Environmental Associates 2020102 L1274449 10/27/20 14:56 70 of 74 ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Excel Civil & Environmental Associates 2020102 L1274449 10/27/20 17:45 70 of 74 ONE LAB.
