1.0 INTRODUCTION

1.1 Project Description

Golder Associates Inc. (Golder) has been contracted by the U.S. Army Corps of Engineers, Alaska District

(USACE) to perform a subsurface exploration program and provide geotechnical and chemical data reports for the CLR 043 Fire Station Project at Clear Air Force Station (AFS), Alaska (Figure 1). Clear AFS is an active and secure United States Government military installation located near Anderson, Alaska.

The CLR 043 Fire Station Project includes a fire station facility, asphalt pavements, and a sanitary sewer lift station. The fire station will be located on a currently undeveloped lot north of Building 200 and west of the baseball field on Clear AFS (Figure 2).

This report summarizes the field work, results of analytical chemistry laboratory testing, and chemical data quality review that was conducted in accordance with the Statement of Work (SOW, Revised 06 December

2016) for Contract No. W911KB-17-D-0002 Task Order No. 0001.

1.2 Purpose and Scope

The work described in this Chemical Data Report was performed to supplement the geotechnical data and determine the presence, if any, of constituents identified in the Sampling and Analysis Plan (SAP) that might impact project design/siting at the CLR 043 Facility. Chemical testing was specified by USACE in the SOW, and reiterated in a Sampling and Analysis Plan (SAP) prepared by Golder. The SAP also outlined sample handling procedures and data quality assurance and quality control requirements for the chemical testing

(Golder 2017a). Prior to conducting the field investigation, the SAP was submitted to the Alaska

Department of Environmental Conservation (ADEC) for review, and a copy was included with the Work

Plan for the overall field investigation (Golder 2017b).

The geotechnical exploration included drilling and sampling to evaluate the subsurface conditions within the project site and determine the engineering characteristics of the foundation soils. Results of the geotechnical exploration and analyses are presented in a separate Geotechnical Data Report (Golder

2017c). Borehole logs from the Geotechnical Data Report are included in this report for completeness and ease of reference.

April 2017 2 1670545

2.0 FIELD INVESTIGATION METHODS

The field investigation was performed in accordance with the Work Plan (Golder 2017b) and chemical sampling and testing was performed as outlined in the SAP (Golder 2017a), as summarized in the following sections. There were no significant changes or deviations from the SAP for this project.

2.1 Subsurface Drilling

The drilling program took place from January 31 through February 6, 2017. This program consisted of drilling and sampling 13 geotechnical boreholes to nominal depths between 15 and 30 feet at the locations shown in Figure 2. The drilling effort was performed by Wininger Drilling (Wininger), of Wasilla, Alaska.

Wininger utilized their truck-mounted Mobile B-53 drill, equipped with 4-inch air rotary equipment to install casing and a 340-pound auto-hammer. Upon completion of the test borings, they were backfilled with drill cuttings or gravel.

The borehole numbers shown on the borehole logs in Appendix A and in Figure 2 are the identification numbers used by Golder in the field (i.e. G17-CLR-01 through G17-CLR-13) and also the permanent identification number assigned by USACE (i.e. AP-2215 through AP-2227) after completion of drilling. Prior to commencing drilling activities, conflicts with underground utilities were cleared through the statewide utility clearance process, as well as through Clear AFS personnel. The completed permits are attached in

Appendix D.

As detailed in Section 3.2, no staining, petroleum odors, sheen, or PID readings above 20 ppm were observed during this investigation; therefore, as detailed in the SAP (Golder 2017a), there were no investigative derived waste (IDW) soil cuttings generated during this project.

2.2 Soil Sampling and Logging

Samples were obtained by collecting either a grab sample for the near-surface interval or by using unlined split-spoon samplers at depth. Split spoon samplers consisted of a three-inch split-barrel tube typically advanced 24 inches into the soil ahead of the air-rotary casing using an automatic hammer equipped with

340-pound hammer weight that free-falls 30 inches. Samples were collected at the surface, 2.5-foot intervals to 10 feet, and at five-foot intervals thereafter.

For samples above the groundwater table, Golder qualified environmental personnel (QEP) conducted field screening (detailed in Section 2.3) immediately after the split spoon sampler was recovered and opened.

Samples selected for analytical laboratory testing (detailed in Section 2.4) were then collected directly from the split spoon sampler following the procedures outlined in the SOW, SAP, and the ADEC Field Sampling

Guidance. Soil samples for geotechnical laboratory testing were collected after those for analytical laboratory testing, and were logged, bagged, and visually classified in the field.

April 2017 3 1670545

2.3 Field Screening

Field screening was performed on all samples, and included inspecting the soil samples for evidence of petroleum hydrocarbons (i.e., sheen, odor, and staining) and testing sample headspace for volatile organic vapors using a photoionization detector (PID) equipped with a 10.6-electronvolt (eV) lamp in accordance with the methods detailed in the SAP.

The PID was calibrated at the beginning of every field day with 100 ppm isobutylene calibration gas and was checked at least twice a day to verify calibration (i.e., bump test), and the PID was recalibrated if the difference between the measured and reference concentration is greater than 5 percent. Using the PID, an initial reading was taken near the undisturbed soil sample immediately after the split spoon sampler was opened, which is referred to as the “cold” reading in the borehole logs in Appendix A. This “cold” reading was only used for sample selection detailed in Section 2.4.1. The sample portion collected for geotechnical testing (detailed in Section 2.2) was used for headspace testing with the PID. For this testing, the samples were placed in a sealed plastic bags and were allowed to equilibrate to a temperature above 40 degrees

Fahrenheit (°F) for at least 15 minutes. The samples were then agitated prior to measuring the concentration of volatile organics in the sample headspace using the PID. The headspace reading is referred to as the “warm” reading in the borehole logs in Appendix A.

2.4 Laboratory Sample Collection

Soil samples were selected and collected during the field exploration for chemical testing according to the

SAP. The collection methods, including sample preparation, handling, and labeling, are detailed in the

SAP. These samples were collected and sent to SGS’s Anchorage laboratory for analytical testing, who performed all the analyses, is ADEC approved for Contaminated Site analysis, and is compliant with U.S.

Department of Defense (DoD) Quality Systems Manual for Environmental Laboratories for the analytical methods used. Sample selection, collection methods, and laboratory testing performed are detailed in the following subsections.

2.4.1 Sample Selection and Analyses

Each of the boreholes had one soil sample selected for analytical testing, generally selected from the sample interval with the highest PID reading, and a second soil sample was also collected one-third of the boreholes. The selected soil samples were submitted to the laboratory for the following chemical testing:

Gasoline Range Organics (GRO), Diesel Range Organics (DRO), Residual Range Organics (RRO), Volatile

Organic Compounds (VOCs), Polycyclic Aromatic Hydrocarbons (PAH), Polychlorinated Biphenyls (PCBs), Pesticides, and the metals arsenic, barium, cadmium, chromium, lead, mercury, nickel, selenium, silver, and vanadium. Testing methods for the laboratory analyses are listed in Tables 1 through 3.

April 2017 4 1670545

2.4.2 Quality Control Samples

2.4.2.1 Field Duplicates

A total of 18 samples were collected for this project. Field duplicate soil samples were collected at a rate of at least 10 percent (one field duplicate per 10 samples) to measure the precision of the sampling and analytical processes. The field duplicate samples were collected simultaneously from the same sample interval using identical methods. Each duplicate was submitted as a blind sample to the laboratory, meaning it was labeled with a sample number different from that of the sample being duplicated. The sample numbers for the duplicates were recorded in the field logbook, and are as follows:

17-CLR043-05Q was a field duplicate of 17-CLR043-05C

17-CLR043-13Q was a field duplicate of 17-CLR043-13D

2.4.2.2 MS/MSD

Matrix spike (MS) and matrix spike duplicate (MSD) samples were used for evaluating potential matrix effects. Additional sample volume was typically collected for MS/MSD samples, and samples designated for MS/MSD analysis were generally indicated on the chain of custody form. MS/MSD analyses were performed at a minimum frequency of five percent, per analyte, and per extraction batch.

2.4.2.3 Trip Blanks

One soil sample trip blank accompanied the shipment of samples that were submitted for volatile compound analyses (all project soil samples were in a single cooler). The trip blank was analyzed to evaluate potential cross-contamination during the sample shipping and analysis process. The soil trip blank was prepared using analyte-free media at the laboratory and was shipped in a 4-oz glass jar with a septa lid.

2.4.2.4 Equipment (Rinsate) Blanks

Equipment (rinsate) blanks were collected and analyzed to evaluate potential cross-contamination due to inadequate decontamination of sampling equipment (i.e., split-spoon sampler). Rinsate blanks were collected by rinsing decontaminated sampling equipment with distilled water, which was collected in sample bottles, preserved, handled, and analyzed in the same manner as the environmental samples. One rinsate blank (17-CLR043-RB1) was collected and analyzed for the full suite of chemical testing (GRO, DRO, RRO, BTEX, PAH, PCB, Pesticides, & Metals). This single rinsate blank represents an approximate frequency of one per 20 samples collected (five percent).

2.5 Field Documentation

Field personnel documented field activities in a field logbook. All entries were written in waterproof ink and contain accurate and inclusive documentation of the field activities. Error corrections were noted using a single line to cross out the entry and were initialed.

April 2017 5 1670545

All pertinent information for the chemical sampling was recorded in the field logbook. The information recorded generally included the following:

Name of project, author, and date and time of entry

Location of activity and site conditions

Names and affiliations of personnel onsite

Field observations and comments

Weather conditions

Rationale for sampling locations and for any changes to sampling protocol

Site sketches

Health and safety comments

Deviations from the SAP

Calibrations and checks of field equipment

All soil sampling information

A copy of the field logbook is attached as Appendix B, and photographs from the investigation are included in Appendix C.

3.0 RESULTS

3.1 General Subsurface Conditions

Based on findings from the current geotechnical field effort, the subsurface conditions at this site generally consist of glacial outwash gravel deposits with varying sand and silt content. The gravel mostly classified as either poorly or well-graded gravel with sand (GP or GW), and as poorly or well-graded gravel with silt and sand (GP-GM or GW-GM). Silty sand or silt (SM or ML) material was observed overlying the outwash deposits in ten of the boreholes, and fill material was observed overlying the outwash deposits in three of the boreholes (Boreholes G17-CLR-08 (AP-2222), G17-CLR-09 (AP-2223) and G17-CLR-13 (AP-2227)).

In two of the boreholes, G17-CLR-05 (AP-2219) and G17-CLR-06 (AP-2220), sand layers (SP-SM) were observed within the gravel deposits near the bottom of the boreholes. Trace organic material was sporadically observed, intermixed within both the near-surface soils and deeper outwash gravel deposits.

The outwash gravel deposit was typically observed at depths starting around five feet below ground surface

(bgs). The average moisture content of the gravel (excluding the sand layers in Boreholes G17-CLR-05

(AP-2219) and G17-CLR-06 (AP-2220)) was two percent, with a maximum of four percent and minimum of one percent. Cobble-sized particles were inferred in the deposits based on direct observation of cobbles in cuttings, and drilling action.

Groundwater in the area is typically encountered at depths greater than 50 feet bgs and was not observed in the boreholes at the time of drilling.

Frozen soil, inferred as seasonal frost and not permafrost, was observed in the boreholes as summarized in the borehole logs. Permafrost was not observed to the depths explored during the geotechnical exploration. The depth of seasonal frost at this site is anticipated to vary with surface conditions.

Subsurface conditions for each borehole are presented on the borehole logs, which are provided in

Appendix A. Additional details of the subsurface conditions encountered are described in the Geotechnical

Data Report (Golder 2017c).

3.2 Field Screening Results

No soil staining, petroleum odors, or sheen on the groundwater was observed while drilling, nor were there

PID measurements of the headspace above 20 ppm. The PID headspace readings ranged from 0.1 to 8.9 ppm, and are presented in the borehole logs in Appendix A.

3.3 Analytical Results

As summarized in Tables 1 through 3, the analytical results for the soil samples collected from the CLR 043

Facility were below ADEC Method 2 cleanup levels, with the exception of arsenic results. The concentrations of arsenic in all samples were above the potential migration to groundwater cleanup level

April 2017 7 1670545

(0.20 mg/kg) that would be applicable for this site, with the results ranging from 3.54 to 20.7 mg/kg (Table

3).

Copies of the laboratory reports are presented in Appendix E, and the completed ADEC Laboratory Data

Review Checklists for those reports are attached to the chemical data quality review (CDQR) that is included in Appendix F.

3.4 Chemical Data Quality Review

The CDQR was performed by the project chemist at Bristol Environmental Remediation Services, LLC

(Bristol) to verify field measurements and analytical methods were performed according to methods in the

SAP, and that project specifications and the laboratory results have been correctly calculated and reported and meet data quality objectives (DQO). As discussed in the attached CDQR report (Appendix F), the results of this investigation and testing conformed to the requirements in the SOW and SAP.

As detailed in the CDQR, the data quality was determined to be acceptable, i.e., results were either associated with QC data that meet all QC criteria, or were associated with QC samples that did not meet

QC criteria but where DQOs were not affected. The data met DQO established for this project, and all reportable results are usable for project purposes. All sample flags recommended by the CDQR are presented in Tables 1 and 3.

April 2017 8 1670545

4.0 CONCLUSIONS

The field screening observations did not indicate evidence of soil staining, petroleum odors, or groundwater sheen. In addition, the concentrations of volatile organic vapors in sample headspace measured using a

PID were all below 20 ppm, and no IDW was generated during the investigation.

Analytical laboratory results for the soil samples collected from the CLR 043 Facility were generally below potential cleanup levels, with the exceptions of arsenic in all samples; as noted in Section 3.3 and summarized in Table 3. The project area is cleared but undeveloped, and there is no known or suspected anthropogenic sources of arsenic at the site related to the historical use. The arsenic concentrations in the tested samples ranged from 3.54 to 20.7 mg/kg, and are likely naturally occurring background levels.
