1 E X E C U T I V E S U M M A R Y The Federal Aviation Administration (FAA) Eastern Service Area Environmental Cleanup (ECU) Program tasked the National Airspace System Implementation Support Contract (NISC) contract team with conducting a Preliminary Assessment/ Site Investigation (PA/SI) for the Washington Dulles International Airport (IAD) National Airspace System Equipment Building (NASEB) following a release of diesel fuel from the NASEB engine generator room. The IAD NASEB facility is co-located with the IAD Localizer (LOC) in Chantilly, Virginia (38.958669, -77.434993). Please see Appendix A to review the site’s location and surrounding areas.

On August 12, 2024, a PA/SI was conducted at the IAD NASEB. Samples were collected to assess the presence or absence of diesel constituents in soil around the site. All samples were analyzed for total petroleum hydrocarbons as diesel-range organics (TPH-DRO) and semi-volatile organic compounds (SVOCs). Based on the analytical results from the PA/SI soil samples, TPH-DRO were identified in one soil sample at concentrations exceeding 100 mg/kg which is the Virginia Department of Environmental Quality (VADEQ) limit. Remedial Action (RA) is recommended for the IAD NASEB facility.

2 I N T R O D U C T I O N The IAD NASEB facility (herein referred to as the “subject property”) is co-located with the IAD LOC on the Washington Dulles International Airport in Chantilly, VA. The subject property is approximately 11 feet by 15 feet. The ground south of the northwestern corner of the IAD NASEB was stained over an area of approximately 8 feet long, 1 foot wide, and 2 inches deep. The building was also stained approximately 9 feet east of the northwestern corner. Another area of ground staining was observed 5.5 feet east of the northwestern corner of the NASEB. Refer to Appendix A for a layout of the site and location of staining.

This trip report documents the sampling activities and results of the PA/SI conducted on behalf of the ESA ECU Program on August 12, 2024. The purpose of this PA/SI was to confirm the presence or absence of diesel constituents in soil surrounding the IAD NASEB facility.

2.1 Site History and Background

The IAD NASEB facility is located on airport grounds at 38.958669, -77.434993. The IAD airport is in Chantilly, Fairfax County, Virginia. FAA records indicate that the IAD NASEB is co-located with the LOC which was commissioned on February 1, 1972. The NASEB has a commercial power source and an emergency engine generator. On May 10, 2024, a release of fuel was reportedly observed on the gravel/soil around the IAD NASEB building at the IAD LOC site. The release appeared to originate from the day tank inside the NASEB building. There is no evidence of fuel reaching any waterbodies or storm drains around the building.

As part of the PA/SI effort, a pollution incident report was submitted to the VADEQ involving the staining at IAD NASEB on May 13, 2024 (Pollution report number #313964).

3.1 Sampling Activities

Field activities performed on August 12, 2024, were first detailed in the PA/SI Sampling and Analysis Plan (SAP). The specific purpose of this PA/SI was to obtain sufficient information to identify constituents of potential concern in soil through sampling and analysis for SVOCs and TPH-DRO(Method 8270C-SIM). This was accomplished by collecting soil samples from the surface (0-6” below ground surface [bgs]) and subsurface (variably within the 10-24” bgs interval) around the IAD NASEB. In total, 15 soil samples were collected for TPH-DRO and SVOC analyses.

All sampling activities conducted at IAD NASEB were performed in accordance with the project SAP and associated standard operating procedures for ECU program activities. All samples were received by the laboratory and confirmed to arrive in good condition.

Figures depicting sampling locations are provided in Appendix A. Copies of field logbooks detailing PA/SI field activities are provided in Appendix B. A photographic log is provided in Appendix C. The analytical results and laboratory data package are provided in Appendix D.

3.2 Sample ID’s

Table 1 contains the sample identifications (ID), analyte, description of sample location, and depth of each sample collected during the PA/SI. Appendix B contains detailed logs of sampling activities. Within each sample ID, the first digit following “IAD” denotes the soil boring location, as shown on the site figures in Appendix A. The depth from which the sample was collected is represented by the letters SS, representing a surface soil sample, or SB, representing a subsurface soil sample).

3.3 Quality Control Samples

Laboratory quality control (QC) samples (e.g., blanks and laboratory control samples) were included in the preparation batch with the field samples and collected per the specifications in the PA/SI SAP.

QC samples were collected to verify that sample results represent actual field conditions. During IAD NASEB PA/SI activities, the following QC samples were collected:

• Duplicate samples were collected at a rate of 10%, or one (1) per ten (10) samples.

o A total of one (1) duplicate sample was collected (from IAD-SB-4).

• Matrix spike/matrix spike duplicate (MS/MSD) samples were collected at a rate of 5%, or one (1) per every twenty (20) samples.

o One (1) MS/MSD sample was collected (from IAD-SS-7).

• Equipment blank samples were collected at the end of each day of sampling during this PA/SI.

o One (1) equipment blank sample was collected (IAD-EB-08122024).

Based on the reported results of the QC sample analysis, no discrepancies were identified in the sample collection or analysis methodologies.

3.4 Sampling Plan Deviations

Based on the planned sampling strategy for the PA/SI activities, minor deviations occurred. A summary of those deviations is provided in Table 2.

Table 2 Sampling Event Deviations

Deviation Summary Corrective Action Impact Could not sample the northwestern corner of NASEB due to the presence of subsurface utilities and wires

Sample locations on the northwest corner of the building were moved to the northeast

The identified exceedance in sample IAD- SS-4 remains unbounded to the north.

Confirmation samples should be collected to confirm that all exceedances have been addressed during the proposed remedial action for this site.

3.5 Field Documentation

Personnel recorded all field activities, sample collection times, and sample locations from August 12, 2024, in a field logbook, a copy of which is presented in Appendix B. Representative photographic documentation was collected and is presented in Appendix C.

Sampling locations identified in the PA/SI SAP were modified by staff in the field based on professional judgment and visual and/or olfactory observations. Final sampling locations are described in Table 1 above and can be reviewed in Appendix A.

4 R E S U L T S Samples were collected around the NASEB building on the IAD airport. The eight (8) surface soil samples were analyzed for TPH-DRO and SVOCs. Only one (1) of these samples contained TPH-DRO at a concentration above the VADEQ TPH soil screening level of 100 mg/kg. Of the five (5) subsurface samples collected and analyzed, none reported screening level exceedances. Please see the full results table in Appendix D and the site figures in Appendix A to review the location of these exceedances.

5 C O N C L U S I O N S A N D R E C O M M E N D A T I O N S The analytical data obtained from PA/SI activities confirmed a single exceedance in surface soil sample IAD-SS-4. This exceedance is bounded by clean samples vertically and horizontally in all directions except to the north which is obstructed by utilities. Based on the analytical results from the SI, a Remedial Action (RA) is recommended to excavate impacted soils for offsite disposal in the area immediately south (up to 5 feet) and west (up to 1.5 feet) of IAD-SS-4. Removal of contaminated soil to the north of IAD-SS-4 should be guided by the use of a photoionization detector (PID).
