1 BACKGROUND

This report has been prepared by Advanced Compliance Solutions Inc. on behalf of Atkins Aviation Services for the Hawaii Air National Guard, 154th Wing, Oahu, Hawaii. Soil Sampling Investigations were performed in preparation for demolition and reconstruction activities within the Munitions Storage Complex. The subject property includes Munitions Maintenance Building (Building 3044) and two (2) Munitions Bunkers (Facilities 3041 and 3042). The purpose of this report is to document soil sampling performed for un-paved areas within the subject property to determine what, if any, contaminants are present in soils and whether overburden requires special handling during demolition and reconstruction activities.

The chemicals of potential concern at HIANG are chlorinated pesticides and metals.

Chlorinated pesticides are synthetic compounds that in the past were legal to apply as insecticides on food crops and as termiticides in and around buildings and homes. Termiticide application was commonly employed by the Navy up until the mid to late 1980s after which the United States prohibited use and commercial production of chlorinated pesticides. Metals were identified as a chemical of potential concern based on historical uses of the subject property in general industry.

2 SAMPLING APPROACH

Only exposed, un-paved areas within the subject property were targeted for soil sampling. Soil sampling was performed on April 30, 2013 by ACSI personnel. The subject property was divided into two (2) Decision Units (DU’s); DUA which included area over and surrounding Buildings 3041 and 3042, and DUB which included the area surrounding Building 3044. DU boundaries are presented in Appendix A. Each DU was sampled using a Multi-Incremental (MI) approach in which thirty (30) discrete samples were composited into one (1) bulk sample for each DU. Sample increments were collected from the top 4-6 inches of soil in a grid like fashion using a hand held trowel and pick axe. Photographs of the sample collection techniques and increments are presented in Appendix C.

Four (4) MI samples were collected at the Munitions Complex; one (1) sample from DU-B and three (3) samples from DU-A. The triplicate samples from DU-A were collected to quantify error introduced through field sampling techniques and spatial variability. Each triplicate sample was comprised of thirty increments collected from approximately 0.5-feet apart in the same grid-like fashion within DU-A. See Appendix A for a pictorial representation of DU sampling boundaries and increments.

Soil sample collection was performed according to guidelines provided in the Hawaii Department of Health (HDOH), Hazard Evaluation and Emergency Response (HEER) Technical Guide Manual. Each sample was sent to the laboratory and analyzed for organochlorine pesticides, EPA Method 8081A and Total Resource Conservation and Recovery Act (RCRA), 8 Metals, EPA Method 6020.

3 RESULTS

Results from soil sampling analysis were compared against Environmental Action Levels (EALs) as set forth by the HDOH HEER Office for commercial/industrial use. None of the results for the Munitions Storage Complex exceeded EALs for any parameter. Thus, no special handling of soil during site preparation and grading is anticipated. Laboratory Results are provided in Appendix A and are summarized in Table 1.

Relative standard deviation for triplicate samples collected from DU-A ranged from 8-15% indicating low spatial variability and consistent field techniques. Strict chain of custody requirements were observed during sample collection and transport to the laboratory for analysis. Chain of Custody forms are included in Appendix A.

Ms. Rietow:

Please find enclosed a data report for the samples analyzed from the above referenced project for ACSI. The samples were received intact. Applicable detection limits, QA/QC data, and any issues encountered during analysis are included in the report.

The following tests were conducted:

Multi-increment sample processing by Hawaii DOH Method.

Analyses for organochlorine pesticides by EPA 8081 mod.

Analyses for total RCRA 8 by EPA 6020.

ESN appreciates the opportunity to have provided analytical services to ACSI on this project. If you have any further questions relating to the data or report, please do not hesitate to contact us.

MULTI-INCREMENT PREPARATION

DATE: 5/1/2013

PREPARED BY: N. Kippen

ESN PROJECT: D1304300203

ACSI personnel collected multi-increment samples in the field for analysis. The samples were delivered to ESN’s lab for preparation and analyses, according to DOH’s Multi-Increment Sampling Plan (HEER TGM, Section 4.2).

(Dry weights) Sample ID# Sample Weight (g)

DUAa 549.5 DUAb 486.0 DUAc 481.5

DUB 603.4

SAMPLE PREP PROCESS SUMMARY:

Each sample was emptied from their containers on to its own clean, flat baking pan. The sample was spread out evenly across the pan no more than 1” high in thickness.

Sample trays were placed on separate oven racks and air-dried overnight or until no significant moisture remained as determined by appearance.

Sample trays were removed and weighed to determine sample’s total dry weight (see above table).

Sieved entire dried sample through a #10 mesh sieve rendering particles less than two-millimeters in size.

Clumps of dirt were crushed until able to pass through the sieve, rocks and other debris were set aside.

Sieved samples were spread out evenly on flat baking pans.

A small flat spatula was used to randomly scoop up 30 to 50 small increments to fill sample containers.

Care was taken during this step to ensure that samples contained a good distribution of particle sizes. If duplicate or triplicate analysis is requested, additional samples are collected at this time. Remaining sample was returned to resealable (i.e. Zip-Loc) bags.

Samples were spread out on flat baking pans and a small flat spatula was used to randomly scoop up 15 to 30 small increments to make up the sample mass for analyses.
