# Executive Summary

There are 18 active and two inac tive, 12.5 million gallon capacity , field

- constructed underground storage tanks (USTs) located at the Red Hill Bulk Fuel Storage Facility (RHSF). Previous environmental site investigations indicated a release had occurred and contaminated the groundwater underlying the RHSF

.
The United States (U.S.) Navy implemented a groundwater monitoring program, which includes collecting quarterly groundwater samples from U.S. Navy W ell 2254

- 01 (RHMW2254

- 01) and four groundwater monitoring wells (RHMW01, RHMW02, RHMW03 , and RHMW05 ) installed in the RHSF lower access tunnel. The U.S. Navy W ell 2254

- 01 is located approximately 3,000 feet downgradient from the RHSF and provides approximately 24 percent (%) of the potable water to the Pearl Harbor Water System (PHWS)

. The groundwater samples are analyzed for petroleum constituents and compared against State of Hawai ‘ i Department of Health (DOH) Drinking Water Environmental Action Levels (EALs ) (DOH, 200 9 ).
In response to increasing concentrations of chemicals of potential concern (COPC s ) in the groundwater monitoring wells within the facility (specifically RHMW02) during 2008, plans were made to conduct four quarterly sampling events starting in August 2009 and ending in April 2010 at the following outside (non

- tunnel) moni toring well locations :
RHMW04;
Oily Waste Disposal Facility M onitoring W ell 01 (OWDFMW01) ; and

H ā lawa Deep Well 2253

- 03 ( HDMW2253

- 03).

The four consecutive quarterly sampling events indicated all COPC concentrations were below the EALs for samples collec ted at monitoring well RHMW04 . In January 2010 concentrations of total petroleum hydrocarbons ( TPH ) diesel range organics ( DRO ) were above the EALs at OWDFMW01 and HDMW 2253

- 03 . As a result, quarterly monitoring was discontinued at RHMW04 and continued at the two remaining outside monitoring wells

. T his groundwater monitoring report presents the analytical results for samples collected on July 21, 201 1 at the two outside monitor ing wells ( OWDFMW01 and HDMW2253

- 03 )

. Laboratory analytical results indicate t hat a ll COPC concentrations during the July 2011 groundwater sampling event were below the EALs

. Dissolved lead was detected in monitoring well s OWDFMW01 and HD MW 2253

- 03 at estimated concentration s of 0

. 27 micrograms per liter ( μ g/L) and 0.12 μ g/L , respec tively

. All other COPCs were not detected at or above the limits of detection (LODs) and limits of quantitation (LOQs ). All LODs and LOQs were generally below t he EALs. In the case where an EAL for a specific COPC is less than the LOQ, it is generally a cceptable to consider the LOQ in place of the EAL (DOH, 2009). The results of this groundwater monitoring event indicate significant concentrations of COPCs detected within the facility are not impacting these two outside monitoring wells.Quarterly Gr oundwater Monitoring Report

# Section 1 Introduction

This report presents the results of the July 2011 quarterly groundwater monitoring event at the two outside monitoring wells (OWDFMW01 and HDMW2253

- 03) at the RHSF, Pearl Harbor
, O‘ahu, Hawai‘i (Figure 1

- 08

- D

- 1930, Contract Task Order (CTO) HC14.
This grou ndwater monitoring event is considered supplemental to the quarterly groundwater monitoring program conducted within the tunnels of the RHSF. This supplemental groundwater monitoring was conducted in response to increasing concentrations of COPCs in a gro undwater monitoring well within the RHSF, specifically RHMW02
, during the October 2008 groundwater monitoring event

. The field activities performed for the July 2011 quarterly groundwater monitoring event were conducted in accordance with the procedures d escribed in the Work Plan

, Long

- Term Monitoring, Red Hill Bulk Fuel Storage Facility, Pearl Harbor, O‘ahu, Hawai‘i (Environet, 2010).


# 1.1 Project Objective

The groundwater monitoring was performed to evaluate the presence of COPCs in groundwater surrounding th e RHSF. The groundwater monitoring was conducted to ensure the DON remains in compliance with DOH UST release response requirements as described in Hawai ‘ i Administrative Rules (HAR) 11

- 281 Subchapter 7, Release Response Action.


# 1.2 Background

The U.S. Navy i mplemented a groundwater monitoring program, which includes collecting quarterly groundwater samples from U.S. Navy W ell 2254

- 01 (RHMW2254

- 01) and four groundwater monitoring wells (RHMW01, RHMW02, RHMW03 , and RHMW05 ) installed in the RHSF lower access tun nel. The U.S. Navy W ell 2254

- 01 is located approximately 3,000 feet downgradient from the RHSF and provides approximately 24 % of the potable water to the PHWS

. The groundwater samples are analyzed for petroleum constituents and compared against DOH Drink ing Water EALs (DOH, 200 9 ).
In response to increasing concentrations of COPCs in the groundwater monitoring wells within the facility (specifically RHMW02) during 2008, plans were made to conduct four quarterly sampling events starting in August 2009 and e nding in April 2010 at the following outside (non

- tunnel) monitoring well locations:

- 2 The four consecutive quarterly sampling events indicated a ll COPC concentrations were below the EALs for samples collected at monitoring well RHMW04. In January 2010 concentrations of TPH

- DRO were above the EALs at OWDFMW01 and HDMW2253

- 03. As a result, quarterly monitoring was discontinued at RHMW04 and contin ued at the two remaining outside monitoring wells . T his groundwater monitoring report presents the analytical results for samples collected on July 21
, 201 1 at the two outside monitor ing wells (OWDFMW01 and HDMW2253

- 03). The following sections provide a description of the site and information on the RHSF and USTs.



## 1.2.1 Site Description
The RHSF is located on the island of O ‘ ahu, Hawai ‘i, approximately 2.5 miles northeast of Pearl Harbor in H ā lawa Heights (Figure 1

- 1) . Land adjacent to the north of the RHSF is occupied by the H ā lawa Correctional Facility and private businesses. Land to the south and west of the facility includes the Coast Guard Reservation and other residential neighborhoods . Moanalua Valley is located east of the facility ( Environet, 2010 ).
The Navy Public Works Department operates a potable water infiltration tunnel approximately 1,550 feet hydraulically downgradient from the RHSF ( Environet, 2010 ). The U.S. Navy W ell 2254

- 01 is located approximately 3,000 feet downgradient (west) of the RH SF and provides approximately 24 % of the potable water to the PHWS , which serves approximately 52,200 military consumers ( The Environmental Company, Inc. ( TEC ) , 2008).



## 1.2.2 Facility Information
The RHSF consists of 18 active and two inactive USTs operated by th e U.S. Naval Supply System Command Fleet Logistics Center
, Pearl Harbor, formerly Fleet and Industrial Supply Center ( FISC ) Pearl Harbor. Each UST has a capacity of 12.5 million gallons. The RHSF is located approximately 100 feet above the basal aquifer ( Dawson Group, Inc. , 2006)

. In 2002, the U.S. Navy installed a groundwater monitoring well (RHMW01) into the basal aquifer, directly down

- gradient from the RHSF, within the lower access tunnel. Groundwater samples from this well indicated that petroleum f rom the RHSF has migrated to the basal aquifer (AMEC Earth and Environmental, Inc., 2002). In 2005, the U.S. Navy began quarterly monitoring of the aquifer to protect their down

- gradient drinking water resource associated with the U.S. Navy Well 2254

- 01.
By September 2005, the U.S. Navy had installed two more groundwater monitoring wells (RHMW02 and RHMW03) within the RHSF UST system, a groundwater monitoring well (RHMW04) north of the RHSF (adjacent to the U.S. Navy Firing Range), and a groundwater monito ring well within the U.S. Navy Well 2254

- 01 infiltration gallery (RHMW2254

- 01). Since 2005, RHMW01, RHMW02, RHMW03, and RHMW2254

- 01 have been sampled quarterly for TPH

- DRO, TPH

- gasoline range organics (GRO), volatile organic compounds (VOCs), polycyclic a romatic hydrocarbons (PAHs), and dissolved lead.
Due to increasing concentrations of COPCs at the groundwater monitoring wells within the RHSF (specifically RHMW02) during 2008, response measures were warranted. In April 2009, another groundwater monitori ng well (RHMW05) was installed within the lower access tunnel@A@A@A@A@A@A@A@A@?@?@?@?@?@?@?@?@?@?@?@?@?@?@?@?@?@?!(OWDFMW01RHMW2254-01RHMW05RHMW01RHMW02RHMW03HDMW2253-03SVMP02SVMP03SVMP04SVMP06SVMP08SVMP10SVMP12SVMP14SVMP16SVMP18SVMP20SVMP05SVMP07SVMP09SVMP11SVMP13SVMP15SVMP17Hālawa Industrial ParkHālawa Correctional FacilityHālawa StreamRHMW04U.S. Navy Well 2254-01Hālawa Shaft Board of WaterSupply Pump Station (2354-01)Coast GuardReservationMoanaluaVillageNavy FiringRange@?Soil Vapor Monitoring Points@AGroundwater Monitoring Wells!(Board of Water Supply Pump StationHalawa Correctional FacilityRed Hill Naval ReservationHālawa Stream1,00001,000500FeetFigure 1-1Groundwater Monitoring WellLocation MapLEGEND ̄USGS, 2005SOURCEPearl HarborQuarterly Groundwater MonitoringReport-Outside (Non-Tunnel) Wells,Red Hill Bulk Fuel Storage Facility,Pearl Harbor, O'ahu, Hawai'iQuarterly Groundwater Monitoring Report

- 5 between RHMW01 and RHMW2254

- 01. It was install ed to identify the extent of contaminant migration in groundwater before it reaches the infiltration gallery at RHMW2254

- 01.
Additionally, plans were made to sample three monitoring wells surrounding and outside of RHSF: RHMW04, OWDFMW01, and HDMW2253

- 03 (Figure 1

- 1 and Table 1

- 1). RHMW04 was installed to evaluate groundwater within the basal aquifer upgradient from RHSF. OWDFMW01 (originally known as MW08) was installed into the basal aquifer in 1998 for a Phase II Remedial Investigation/Feasibility Stu dy for the Red Hill Oily Waste Disposal Facility (Earth Tech, Inc., 2000). It is located geographically down

- gradient of the USTs and U.S. Navy Well 2254

- 01. HDMW2253

- 03 is controlled by the State of Hawai ‘ i Commission on Water Resource Management. HDMW 2253

- 03 is located between the RHSF and the municipal drinking water supply well which is operated by the City and County of Honolulu Board of Water Supply (Hālawa Shaft Pumping Station 2354

- 01) (Figure 1

## 1.2.3 UST Information The USTs were constructed in the early 1940s. The tanks were constructed of steel and currently contain Jet Propellant (JP)

- 5 fuel, JP

- 8, and marine diesel fuel (F

- 76). Previously, several tank s stored Navy Special Fuel Oil, Navy Distillate, aviation gasoline, and motor gasoline. Each tank measures approximately 245 feet in height and 100 feet in diameter. The upper domes of the tanks lie at depths varying between approximately 100 feet and 20 0 feet below the existing ground surface (TEC, 2006).



## 1.2.4 Regulatory Updates During the summer and fall of 2008, DOH updated their EALs, which resulted in significant changes to the action levels associated with methylnaphthalenes. The drinking water toxici ty EAL for these compounds was 240 μ g/L. This concentration presumed that methylnaphthalenes

were non

- carcinogenic. Evidence that they are human carcinogens has now been accepted by the U.S. Environmental Protection Agency (EPA). As a result, DOH adopte d more rigorous EALs of 4.7 μ g/L for 1

- methylnaphthalene and 24 μ g/L for 2

- methylnaphthalene, corresponding to a residential tap water scenario, and a one in a million cancer risk (DOH, 2009).
Also, the drinking water EAL for naphthalene was increased from 6.2 μ g/L to 17 μ g/L (DOH, 2009). Finally, the DOH Drinking Water EAL for TPH

- DRO was increased from 100 μ g/L to 210 μ g/L, although the DOH Groundwater Gross Contamination EAL for TPH

- DRO remains 100 μ g/L.Quarterly Groundwater Monitoring Report

# Section 2 Monitoring Activities

G roundwater monitoring was conducted on July 21, 2011 in ac cordance with the site specific Work Plan (Environet, 2010). Field activities were documented in the field notebook (Appendix A)

. 

# 2.1 Groundwater Gauging

Groundwater gauging measurements were collected at the two monitoring well s (OWDFMW01 and HDMW2253

- 03) pr ior to purging and sample collection. A Solinst water level meter was used to measure the depth to groundwater to the nearest 0.01 foot within monitoring well OWDFMW01, according to the proced ure s described in Procedure I

- C

- 3, Monitoring Well Sampling ( DO N , 2007). The depth to groundwater for monitoring well HDMW2253

- 03 was measured by a Department of Land and Natural Resources ( DLNR ) employee prior to well purging (Table 1

- 1).


# 2.2 Groundwater Sampling
Groundwater samples were collected from the two monitorin g wells according to the procedures described in Procedure I

- C

- 3, Monitoring Well Sampling ( DON , 2007).



## 2.2.1 Monitoring Well Purging
Due to the well construction characteristics of OWDFMW01 and HDMW2253

- 03 ( large casing diameter o f approximately 12 inches from the top of casing (TOC) to approximately 50 feet below the groundwater surface then the well is open [not cased] from approximately 250 f eet below TOC (bTOC) to 1, 575 feet bTOC ), three well casing volumes were not purged prior to sampling. Instead, water was purged using disposable bailers until three or more successive water quality parameter measurements had stabilized within 10 % . A Horiba ® 

### U

- 22 multi

- parameter water quality meter was used to measure hydrogen activity (pH), temperature, specific conduct ivity, dissolved oxygen, turbidity, and oxidation reduction potential. At least six readings were recorded on Groundwater Sampling Log data sheets (Appendix B)

. 

## 2.2.2 Groundwater Sample Collection
G roundwater samples were collected from OWDFMW01 and HDMW2253

- 03 using four

- inch and two

- inch disposable bailers. Groundwater samples were collected directly into laboratory provided
, specially cleaned sample containers already containing the appropriate preservatives (i.e., nitric acid for dissolved lead analysis). The dissolved lead samples were filtered in the field and placed in polyethylene bottles containing the appropriate preservative.



## 2.2.3 Sample Management and Shipment Each sample container sent to the laboratory was assigned a project

- specific chain of custody i dentification number and a descriptive identification number. The sample identifiers provided specific data unique to each sample and were entered into the field notebook. The samples were labeled according to the procedures described in Procedure III

- 2 Following sample collection and labeling, the sample containers were packaged with bubble
wrap and placed into individual ZipLoc bags, then immediately into insulated coolers with ice for preservation. The samples were shipped via FedEx to the laboratory on the same day of collection. The samples were managed under standard chain of custody protocol and documentation from collection to delivery to the laboratory. Sample handling, storag e, and transport were performed according to the requirements described in Procedure III

- F, Sample Handling, Storage, and Shipping ( DON , 2007).


# 2.3 Analytical Program
During the July 2011 groundwater monitoring event
, two sets of primary groundwater samples,

o ne set of duplicate groundwater sample s , and one set of quality control (QC) groundwater sample s were submitted to APPL, Inc. located in Clovis
, California

. Groundwater samples were analyzed for VOCs and TPH

- GRO by EPA Method 8260B, TPH

- DRO by EPA Method 8015B, PAHs by EPA Method 8270D SIM, and dissolved lead by EPA Method 6020. The results of the laboratory analyses are presented and discussed in Section 3

. 

# 2.4 Field Quality Control Samples
Field QC procedures were followed to ensure viability and integrity of sample analytical data. Field duplicates were collected according to the procedure s described in Procedure III

- B, Field QC Samples (Water, Soil) ( DON , 2007) and the Work Plan (Environet, 2010). Field duplicate samples were collected at a minimum of 1 0 % of primary samples and analyzed for the same contaminants. Field rinsate samples were not required since disposable bailers were used.


# 2.5 Laboratory Quality Control Samples
Laboratory QC samples were analyzed as part of the standard laboratory QC protoco ls as presented in the Work Plan (Environet, 2010). Laboratory QC for the groundwater monitoring event consisted of matrix spike (MS)/matrix spike duplicate (MSD) samples for organic analysis. Laboratory QC samples were collected and analyzed according t o the procedure s described in Procedure III

- A Laboratory QC Samples (Water, Soil) ( DON , 2007). Laboratory QC MS/MSD samples are an aliquot (i.e., a subset) of the field sample ; t hey are not separate samples, but a special designation of an existing sample . Laboratory QC MS/MSD samples were analyzed for the same constituents as the standard samples. At a minimum, one MS/MSD sample pair was required per 20 samples, including duplicates.


# 2.6 Equipment Decontamination

Decontamination of monitoring equipment wa s performed to ensure data quality, to prevent cross contamination, and to prevent the potential introduction of contaminants into previously

un

- impacted areas. Decontamination of monitoring equipment (i.e., Solinst water level meter and Horiba ®

# Section 3 Groundwater Analytical Results

This section provides a summary of analytical results for groundwater samples collected from the two outside monitoring wells on July 21, 201 1

. Complete analytical laboratory reports are provided in Appendix C

. 

# 3.1 Summary of Groundwater Analytical Results

OWDFMW01
Dissolved lead was detected in samples collected from OWDFMW01 at an estimated concentration of 0. 27 μ g/L which is below both the Drinking Water EAL ( 1 5 μ g/L ) and the Gross Cont amination EAL ( 5,000 μ g/ ) (Table 3

- 1 , Table 3

- 2 )

.
All other COPCs were not detected at or above the LODs and LOQs in samples collected from OWDFMW01

. All LODs and LOQs were generally below the EALs. In the case where an EAL for a specific COPC is less th an the LOQ, it is generally acceptable to consider the LOQ in place of the EAL (DOH, 2009).

HDMW2253

- 03
Dissolved lead was detected in sample collected from HDMW2253

- 03 at an estimated concentration of 0. 12 μ g/L which is below both the Drinking Water EAL ( 1 5 μ g/L) and the Gross Contamination EAL ( 5,000 μ g/L) (Table 3

- 1).

All other COPCs were not detected at or above the LODs and LOQs in samples collected from HDMW2253

- 03

. All LODs and LOQs were generally below the EALs. In the case where an EAL for a spec ific COPC is less than the LOQ, it is generally acceptable to consider the LOQ in place of the EAL (DOH, 2009).



## 3.1.1 Data Quality Control Results
The laboratory quality control results were all within the control limits. The relative percent difference (RPD) o f field duplicates for all analytes were within the 50 % criteria. The trip blank that accompanied the outside well samples did not contain detectable levels of any COPCs

. The data quality control results indicate that the data obtained for this monitorin g event are suitable for their intended use (Table 3

- 2).


# 3.2 Groundwater Contaminant Trend

Concentrations of PAHs and VOCs were previously not detected above the EALs during the August 2009, October 2009, January 2010, April 2010, July 2010
, October 2010 , Janu ary 2011
, and April 2011 groundwater monitoring events. These constituents were also not detected above the EALs during this July 2011 groundwater monitoring event.

- 2 2011 , and July 2011 ( Table 3

- 1 and Table 3

- 3 ). The c oncentration s of TPH

- DRO at HDMW2253

- 03 have decreased to non

- detect for six consecutive groundwater monitoring events (Table 3

- 3).

The October 2010 detection of acetone at an estimated concentration below the DOH Drinking Water EAL w as the first at monitoring well OWDFMW01. Acetone was also detected at an estimated concentration in the trip blank sample

. This suggested that acetone was introduced to the samples during transport to and from the laboratory, and is not representative of groundwater at OWDFMW01. The previous conclusion that acetone is not representative of groundwater at OWDFMW01 is confirmed in the Januar y 2011 , April 2011 , and July 2011 sampling event s as acetone was not detected in any of the samples collected

. The October 2010 detections of lead at concentrations below the DOH Drinking Water EAL were the first at these two monitoring wells (OWDFMW01 and HDMW2253

- 03). Lead was not detected in any of the samples in the January 2011 sampling event or during April 2011

. Estimated concentrations of lead below the DOH Drinking Water EAL were detected at both wells during this July 2011 groundwater sampling e vent

.
The January 2011 detection of benzene at an estimated concentration below the DOH Drinking Water EAL in OWDFMW01 was the first at this monitoring well. Benzene was detected at an estimated concentration in the duplicate sample collected from OWDFMW0 1 in April 2011, however it was no t detect ed in this July 2011 groundwater sampling event

. The April 2011 detections of x ylenes and toluene in OWDFMW01 and b enzene in HDMW2253

- 03 at estimated concentration s below the DOH Drinking Water EALs were the first
at these monitoring wells.Table 3-1: Analytical Results for Quarterly Groundwater Monitoring-Outside (Non-Tunnel) Wells, July 2011

# Section 4 Summary

, Conclusions , and Recommendations

4.1 Summary

Dissolve d lead was detected at estimated concentration s of 0

. 27 μ g/L and 0.12 μ g/L in monitoring wells OWDFMW01 and HDMW2253

- 03 , respectively, during this gro undwater monitoring event

. Th ese concentration s are below the DOH Drinking Water EAL ( 1 5 μ g/L) and the DOH Gross Contamination EAL ( 5,000 μ g / L ) . No other COPCs were detected in OWDFMW01 or HDMW2253

- 03 during the July 201 1 groundwater sampling event

. 

# 4.2 C on clusions
Concentrations of PAHs and VOCs were previously not detected above the EALs during the August 2009, October 2009, January 2010, April 2010, July 2010
, October 201 0
, January and April 2011 groundwater monitoring events. These constituents were als o not detected above the EALs during this groundwater monitoring event. The data continue to suggest that TPH

- DRO is the only COPC present in any notable quantity for the site.

TPH

- DRO concentrations in OWDFMW01 have significantly decreased from Jan uary 2 010 (1,490 μg/L ) to April 2010 (288 μg/L ) and was no t detect ed the previous four groundwater sampling events (Table 3

- 1 and Table 3

- 3 ). The c oncentrations of TPH

- DRO at HDMW2253

- 03 have decreased to non

- detect able levels for the previous six consecutive q uarterly sampling events. The data suggest that TPH

- DRO concentrations are attenuating naturally at the two outside wells

.
The October 2010 detection of acetone at an estimated concentration below the DOH Drinking Water EAL was the first at monitoring wel l OWDFMW01

. Acetone was also detected at an estimated concentration in the trip blank sample. Acetone was not detected in the subsequent two sampling event s . This strongly suggests that acetone was introduced to the samples during transport to and from the laboratory. The October 2010 detection of acetone is not representative of groundwater at OWDFMW01.
The October 2010 detections of lead at concentrations below the DOH Drinking Water EAL were the first at these two monitoring wells (OWDFMW01 and HDM W2253

- 03). L ead was not detected in any sampl es during the January 2011 sampling event or during the April 2011 sampling event. Lead was detected at estimated concentrations below the DOH Drinking Water EAL at both monitoring wells during this July 2011 sampling event

. The January 2011 detection of benzene at an estimated concentration below the DOH Drinking Water EAL in OWDFMW01 was the first at this monitoring well . Benzene was again detected only in the duplicate sample from OWDFMW01 at an estimated c oncentration below the DOH Drinking Water EAL during the April 2011 sampling event

. B enzene was no t detect ed in either OWDFMW01 or HDMW2253

- 03 during this July 2011 sampling event

- 2 The April 2011 detections of xylenes and toluene in OWDFMW01 and benzene i n HDMW2253

- 03 at estimated concentrations below the DOH Drinking Water EALs were the first at these monitoring wells. Xylenes, toluene and benzene were non

- detect in both OWDFM01 and HDMW2253

- 03 during this July 2011 sampling event.


# 4.3 Recommendations

All CO PC concentrations have been below the EALs for four and six consecutive quarterly sampling events for samples collected at monitoring wells OWDFMW01 and HDMW2253

- 03, respectively. Discontinuation of the quarterly groundwater monitoring of both monitoring wells is recommended
