RE: Soil Characterization Summary Letter

I-Range 7505 Pocasset-Forestdale Road

Camp Edwards, Massachusetts 02542

Dear Mr. Johnson:

The Vertex Companies, LLC (VERTEX) is pleased to submit this summary letter and laboratory results regarding the characterization of the soil proposed for on-site reuse or disposal at the I- Range on Camp Edwards, MA (the Site).

This document provides a summary of the I-Range Berm sampling and laboratory analysis.

Range Berm Sampling

Based on information provided by the Client and site observations, the I-Range Berm consists of approximately 8,000 cubic yards (cy). Ammunition reportedly authorized for use at the I-Range only includes Enhanced Performance Rounds (ERP) which generally consist of copper casings and slugs. EPRs are reportedly lead free.

Approximately 700 cy of soil is pending characterization for potential off-site transport. The client reported that approximately thirty (30) inches of soil from the front side of the Range Berm is proposed to be removed.

VERTEX collected representative soil samples from subsections of the Range Berm as 10-point composites. One of the composite samples was collected from Firing Line 1-10 (CS-108-01). The other composite sample was collected from Firing Line 10-20 (CS-108-02). The composite samples were collected in a grid pattern in the respected subsection. Individual locations of the 10-point composite samples were collected from approximately 3” to 23” inches below the surface.

I-Range Soil Characterization

The two (2) composite soil samples collected in laboratory-supplied pre-cleaned containers, stored on ice, and transferred under chain of custody to Pace Analytical Services, of Westborough, Massachusetts for laboratory analysis, including:

Volatile organic compounds (VOCs) by United States Environmental Protection Agency (USEPA) Method 8260;

Semi-volatile organic compounds (SVOCs) by USEPA Method 8270;

Total petroleum hydrocarbons (TPH) by USEPA Method 8100;

MCP-14 metals by USEPA Methods 6010/7471;

Polychlorinated biphenyls (PCBs) by USEPA Method 8082;

Corrosivity (pH) by USEPA Method 9040C/9045D;

Conductivity by USEPA Method 9050A;

Ignitability by USEPA Method 1010;

Reactivity (cyanide and sulfide) by USEPA Method 7.3; and/or, Total solids by USEPA Method SM-2540B

Soil Screening

During the subsurface investigations, soil samples were screened in the field for the presence of total VOCs (TVOCs) using a 10.6 electron volt photoionization detector (PID) calibrated with a 100 parts per million by volume (ppmv) isobutylene gas standard to provide readings of ionizable TVOCs as isobutylene equivalents. In general, TVOC concentrations were non detected during the screening activities. The TVOC concentrations measured at each composite sample location are included in Table 1.

Soil Lithology

Based on visual classification of soils collected during the composite sampling, soils throughout the range berm generally consisted of light to dark brown fine to coarse sand with varying amounts of silt and trace organics from 0”-12” and then medium sand at 12” and beyond. Visual and olfactory evidence of impacts in soil were not observed during the subsurface investigations.

I-Range Soil Characterization

Conclusion

Based on the review of the attached analytical results, the representative composite soil samples did not exceed standards per 310 CMR 40.0361(1)(a)(2), as the location is subject to the RCS-1 Reportable Concentrations, listed at 310 CMR 40.1600 and as such, the soil will be transported and managed to an appropriate off-site facility.

Please do not hesitate to contact us should you have any questions or require additional information.

Sincerely, The Vertex Companies, LLC

Case Narrative

The samples were received in accordance with the Chain of Custody and no significant deviations were encountered during the preparation or analysis unless otherwise noted. Sample Receipt, Container Information, and the Chain of Custody are located at the back of the report.

Results contained within this report relate only to the samples submitted under this Pace Lab Number and meet NELAP requirements for all

NELAP accredited parameters unless otherwise noted in the following narrative. The data presented in this report is organized by parameter

(i.e. VOC, SVOC, etc.). Sample specific Quality Control data (i.e. Surrogate Spike Recovery) is reported at the end of the target analyte list for each individual sample, followed by the Laboratory Batch Quality Control at the end of each parameter. Tentatively Identified

Compounds (TICs), if requested, are reported for compounds identified to be present and are not part of the method/program Target

Compound List, even if only a subset of the TCL are being reported. If a sample was re-analyzed or re-extracted due to a required quality control corrective action and if both sets of data are reported, the Laboratory ID of the re-analysis or re-extraction is designated with an "R" or "RE", respectively.

When multiple Batch Quality Control elements are reported (e.g. more than one LCS), the associated samples for each element are noted in the grey shaded header line of each data table. Any Laboratory Batch, Sample Specific % recovery or RPD value that is outside the listed

Acceptance Criteria is bolded in the report. In reference to questions H (CAM) or 4 (RCP) when "NO" is checked, the performance criteria for CAM and RCP methods allow for some quality control failures to occur and still be within method compliance. In these instances, the specific failure is not narrated but noted in the associated QC Outlier Summary Report, located directly after the Case Narrative. QC information is also incorporated in the Data Usability Assessment table (Format 11) of our Data Merger tool, where it can be reviewed in conjunction with the sample result, associated regulatory criteria and any associated data usability implications.

Soil/sediments and solids are reported on a dry weight basis unless otherwise noted. Tissues are reported "as received" or on a wet 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, Pace'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 Pace Project Manager and made arrangements for Pace 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.

In reference to question H:

A Matrix Spike was not submitted for the analysis of Total Metals.

Volatile Organics

In reference to question H:

L2667281-01 and -02: Initial Calibration did not meet:

Lowest Calibration Standard Minimum Response Factor: 1,2-Dichloropropane (0.1995), 1,4-Dioxane (0.0028), cis-1,3-Dichloropropene (0.2889), trans-1,3-Dichloropropene (0.2676), 1,1,2-Trichloroethane (0.1486)

Average Response Factor: 1,4-Dioxane

L2667281-01 and -02: The associated continuing calibration standard is outside the acceptance criteria for several compounds; however, it is within overall method allowances. Associated results are considered to be biased high if the %D is negative and biased low if the %D is positive. A copy of the continuing calibration standard is included as an addendum to this report.

Total Metals

L2667281-01 and -02: The sample has elevated detection limits for all elements, with the exception of mercury, due to the dilution required by the sample matrix.

I, the undersigned, attest under the pains and penalties of perjury that, to the best of my knowledge and belief and based upon my personal inquiry of those responsible for providing the information contained in this analytical report, such information is accurate and complete. This certificate of analysis is not complete unless this page accompanies any and all pages of this report.
