Executive Summary 

This quarterly groundwater monitoring report presents the results of groundwater sampling 

conducted on October 13, 2009 at locations surrounding the United States (US) Navy Bulk Fuel 

Storage Facility at Red Hill, Oahu, Hawaii (the Facility). The sampling and reporting was 

conducted by TEC Inc. (TEC) for the Fleet and Industrial Supply Center (FISC) at Pearl Harbor, 

Hawaii. This report is part of a series of quarterly groundwater monitoring reports, supplemental 

to the groundwater reports for the groundwater monitoring wells within the Facility, provided by 

the US Navy to the State of Hawaii Department of Health (HDOH) in accordance with HDOH’s 

release response requirements. Currently, there are 18 active and 2 inactive, 12.5 million gallon, 

field-constructed underground storage tanks (USTs) located at the Facility. 

Background 

In 2002, the US Navy installed a groundwater monitoring well (currently named RHMW01) into 

the basal aquifer, directly down-gradient from the Facility, within the lower access tunnel. 

Groundwater samples from this well indicated that petroleum from the Facility has migrated to 

the basal aquifer (AMEC, 2002). In 2005, the US Navy began quarterly monitoring of the 

aquifer to protect their down-gradient drinking water resource associated with the US Navy Well 

2254-01. US Navy Well 2254-01 is located approximately 3,000 feet down-gradient from the 

Facility USTs and provides approximately 24% of the potable water to the Pearl Harbor Water 

System (PHWS). 

By September 2005, the US Navy had installed two more groundwater monitoring wells 

(RHMW02 and RHMW03) within the Facility UST system and a groundwater monitoring well 

within the US Navy Well 2254-01 infiltration gallery (RHMW2254-01). Since 2005, these wells 

have been sampled quarterly for Total Petroleum Hydrocarbons (TPH) quantified as DieselRange Organics (DRO) and Gasoline Range Organics (GRO), Volatile Organic Compounds 

(VOCs), Polynuclear Aromatic Hydrocarbons (PAHs), and dissolved lead. 

In response to increasing concentrations of contaminants of potential concern at the groundwater 

monitoring wells within the facility (specifically RHMW02) during 2008, plans were made to 

conduct quarterly sampling at the following monitoring well locations: 

 RHMW04, up-gradient of the Facility; 

 Oily Waste Disposal Facility monitoring well 01 (OWDFMW01), down-gradient of the 

Facility; and 

 Halawa Deep Well 2253-03 (referred to as HDMW2253-03 in this report). 

During the summer and fall of 2008, HDOH updated their Environmental Action Levels (EALs), 

which resulted in significant changes to the action levels associated with methylnaphthalenes. 

The HDOH Drinking Water toxicity EAL for these compounds was 240 g/L. This 

concentration assumed that methylnaphthalenes were not human carcinogens. Once evidence 

emerged and was accepted by the US Environmental Protection Agency (USEPA) that 

methylnaphthalenes are carcinogenic to humans, HDOH adopted more rigorous EALs of 4.7 

g/L for 1-methylnaphthalene and 24 g/L for 2-methylnaphthalene (HDOH, 2008).

Red Hill Fuel Storage Facility December 2009 

 ____________________________________________________________________________________________ 

2 

The HDOH Drinking Water EAL for naphthalene was also updated during this process. 

Previously, HDOH based their naphthalene EAL on USEPA Region 9 Preliminary Remediation 

Goal (USEPA PRG) of 6.2 g/L, which is associated with a non-cancer Hazard Index of 1. In 

deference to the California Department of Public Health’s Drinking Water Notification Levels, 

(HDOH, 2008) HDOH updated their naphthalene drinking water EAL to 17 g/L. 

Finally, the HDOH Drinking Water EAL for TPH-DRO was increased from 100 g/L to 210 

g/L, although the Groundwater Gross Contamination EAL for TPH-DRO remains 100 g/L. 

Current Results 

On October 13, 2009, three groundwater samples (i.e., RHMW04, OWDFMW01, and 

HDMW2253-03), along with the required quality control samples (duplicate, matrix spike, and 

matrix spike duplicate) were collected for analysis. Samples were analyzed for TPH-DRO, 

TPH-GRO, VOCs, PAHs, and dissolved lead. 

No HDOH Drinking Water EALs were exceeded and no contaminants of concern were detected 

above the laboratory method detection limit (MDL). 

Conclusions and Recommendations 

Based on the October 2009 sampling event, there is no indication of contaminant migration from 

the Facility. Quarterly groundwater sampling for TPH-DRO, TPH-GRO, VOCs, PAHs, and 

dissolved lead will continue at the Facility until such time that data indicates that a different 

monitoring plan is warranted.

1.0 Introduction

This report presents the results of the second groundwater sampling event, conducted in October 

2009 at three groundwater monitoring wells (i.e., RHMW04, OWDFMW01, and HDMW2253-

03), surrounding the Red Hill Fuel Storage Facility, Oahu, Hawaii (hereafter referred to as “the 

Facility”). The Facility consists of 18 active and 2 inactive USTs operated by FISC, Pearl 

Harbor. This groundwater sampling and analysis event is supplemental to the quarterly 

groundwater sampling and analysis at groundwater monitoring wells within the Facility (i.e., part 

of the groundwater monitoring program for the UST site in response to past UST releases, 

previous environmental investigations, and recommendations from the HDOH). 

1.1 Project Objective 

This groundwater sampling project was performed to evaluate the presence of chemicals of 

potential concern in groundwater surrounding the Facility. The project was conducted to ensure 

the Navy remains in compliance with HDOH UST release response requirements. The 

groundwater sampling program followed the procedures described in Red Hill Bulk Fuel Storage 

Facility Groundwater Protection Plan [TEC Inc. (TEC), 2008], also referred to as “the Plan”. 

This groundwater sampling event was conducted by TEC under US Navy Contract Number 

N47408-04-D-8514, Task Order No. 54, Amendment/Modification No. 01. 

1.2 Previous Reports 

This is a quarterly sampling event that is being conducted to supplement the quarterly

1.3 Background 

The following sections provide a description of the site and information on the Facility and USTs. 

1.3.1 Site Description 

The Facility is located in Halawa Heights on Oahu, Hawaii. Land adjacent to the north of the 

Facility is occupied by Halawa Correctional Facility and private businesses. Land to the south 

and west of the Facility includes the Coast Guard Reservation. Moanalua Valley is located east 

of the Facility (Dawson, 2006). 

The Navy Public Works Department operates a potable water infiltration tunnel approximately 

1,550 feet hydraulically down-gradient from the Facility (Dawson, 2006). The US Navy Well 

2254-01 is located approximately 3,000 feet down-gradient (west) of the Facility and provides 

approximately 24% of the potable water to the Pearl Harbor Water System, which serves 

approximately 52,200 military consumers (TEC, 2008). 

1.3.2 Facility Information 

The Facility consists of 18 active and 2 inactive USTs operated by Navy FISC Pearl Harbor. 

Each UST has a capacity of 12.5 million gallons. The Facility is located approximately 100 feet 

above the basal aquifer (Dawson, 2006). 

In 2002, the US Navy installed a groundwater monitoring well (currently named RHMW01) into 

the basal aquifer, directly down-gradient from the Facility, within the lower access tunnel. 

Groundwater samples from this well indicated that petroleum from the Facility has migrated to 

the basal aquifer (AMEC, 2002). In 2005, the US Navy began quarterly monitoring of the 

aquifer to protect their down-gradient drinking water resource associated with the US Navy Well 

2254-01. US Navy Well 2254-01 is located approximately 3,000 feet down-gradient from the 

Facility USTs and provides approximately 24 % of the potable water to the PHWS. 

By September 2005, the US Navy had installed two more groundwater monitoring wells 

(RHMW02 and RHMW03) within the Facility UST system, a background groundwater 

monitoring well (RHMW04) up-gradient from the Facility adjacent to the US Navy Firing Range, 

and a groundwater monitoring well within the US Navy Well 2254-01 infiltration gallery 

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

been sampled quarterly for TPH-DRO, TPH-GRO, VOCs, PAHs, and dissolved lead. 

Due to increasing concentrations of contaminants of potential concern at the groundwater 

monitoring wells within the Facility (specifically RHMW02) during 2008, response measures 

were warranted. In April 2009, another groundwater monitoring well (RHMW05) was installed

down-gradient from the USTs, within the lower access tunnel between RHMW01 and 

RHMW2254-01. It was installed to identify the extent of contaminant migration down-gradient 

before it reaches the infiltration gallery at RHMW2254-01. 

Additionally, plans were made to sample three monitoring wells surrounding the Facility, 

RHMW04, OWDFMW01, and HDMW2253-03. RHMW04 is adjacent to the US Navy Firing 

Range, geographically up-gradient of the USTs. It was installed to provide geochemistry for 

water moving through the basal aquifer beneath the Facility. OWDFMW01 (originally known as 

MW08) was installed into the basal aquifer in 1998 for a Phase II Remedial Investigation/ 

Feasibility Study for the Red Hill Oily Waste Disposal Facility (Earth Tech Inc., 2000). It is 

located geographically down-gradient of the USTs and US Navy Well 2254-01. HDMW2253-

03 is controlled by the State of Hawaii Commission on Water Resource Management. It is 

located cross-gradient of the Facility, between the Facility and the municipal drinking water 

supply well run by the City and County of Honolulu Board of Water Supply (Halawa Shaft 

pumping station 2354-01). 

Table 1 summarizes basic groundwater monitoring well information, Figure 1 shows 

groundwater monitoring well locations, and Appendix B includes the well construction logs for 

RHMW04 and OWDFMW01.

1.3.3 UST Information 

The USTs were constructed in the early 1940s. The tanks were constructed of steel and currently 

contain Jet Propulsion (JP)–5 fuel and F-76 (diesel marine fuel). Previously, several tanks 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 200 feet below the existing 

ground surface (TEC, 2006). 

1.4 Regulatory Updates 

During the summer and fall of 2008, HDOH updated their EALs, which resulted in significant 

changes to the action levels associated with methylnaphthalenes. The drinking water toxicity 

EAL for these compounds was 240 g/L. This concentration presumed that methylnaphthalenes 

were non-carcinogenic. Evidence that they are human carcinogens has now been accepted by the 

US Environmental Protection Agency (USEPA). As a result, HDOH adopted more rigorous 
Quarterly Groundwater Monitoring Report

6 

EALs of 4.7 g/L for 1-methylnaphthalene and 24 g/L for 2-methylnaphthalene, corresponding 

to a residential tap water scenario, and a 1 in a million cancer risk (HDOH, 2008). 

The drinking water EAL for naphthalene has also been updated during this process. Previously, 

HDOH based their naphthalene EAL on USEPA Region 9 Preliminary Remediation Goal 

(USEPA PRG) of 6.2 g/L, which is associated with a non-cancer Hazard Index of 1. HDOH 

has updated their naphthalene drinking water EAL to 17 g/L, in deference to the California 

Department of Public Health’s Drinking Water Notification Levels, a Hazard Index of 2.7 

(HDOH, 2008). 

Finally, the HDOH Drinking Water EAL for TPH-DRO was increased from 100 g/L to 210 

g/L, although the HDOH Groundwater Gross Contamination EAL for TPH-DRO remains 100 

g/L. 

2.0 Sample Collection and Analyses 

Field activities relating to groundwater sample collection were conducted on October 13, 2009. 

Groundwater samples were collected from three monitoring wells, RHMW04, OWDFMW01, 

and HDMW2253-03. Sampling and analysis were conducted according to Red Hill Bulk Fuel 

Storage Facility Groundwater Protection Plan (TEC, 2008). A total of six samples were 

collected as follows: 

 one environmental sample from RHMW04, OWDFMW01, and HDMW2253-03; 

 one duplicate sample from RHMW04 (sampled as RHMWA01 and reported as 

RHMW04D); and 

 one matrix spike and matrix spike duplicate from OWDFMW01. 

2.1 Monitoring Well Purging

RHMW04 and OWDFMW01 were purged and sampled using a dedicated pump system. Well 

purging was considered complete when no less than three successive water quality parameter 

measurements had stabilized within approximately 10 percent. Field parameters were measured 

at regular intervals during well purging and included pH, temperature, specific conductivity, 

dissolved oxygen, and turbidity. Due to the well construction characteristics of HDMW2253-03, 

the well was not purged prior to sampling, but field parameters were recorded. Rather than 

purging, a grab sample was collected at a depth below the solid casing (which extends about 50 

feet below the water table) and within the open-holed portion of the well. 

2.2 Groundwater Sample Collection 

Immediately following purging, RHMW04 and OWDFMW01 were sampled directly from their 

dedicated bladder pump system. HDMW2253-03 was sampled using a disposable bailer 

designed to collect samples at desired depths. Samples were placed into sampling containers 

with appropriate preservatives [i.e., hydrochloric acid (HCl) for volatile organic analysis, nitric 

acid (HNO3) for dissolved lead]. Dissolved lead samples were filtered in the field and placed in 

preserved bottles. Sample containers were labeled with the date, sample identification number, 

type of analysis, and sampler’s name. The containers were placed on ice in sample coolers and 

transported under chain-of-custody procedures to the certified laboratory for analysis.
