Executive Summary

There are 18 active and two inactive, 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 Well 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 Well 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, 2009).

In response to increasing concentrations of chemicals of potential concern (COPCs) in the 

groundwater monitoring wells within the facility (specifically RHMW02) during 2008, plans 

were made to conduct four quarterly monitoring events starting in August 2009 and ending in 

April 2010 at the following outside (non-tunnel) monitoring well locations:

• RHMW04;

• Oily Waste Disposal Facility Monitoring Well 01 (OWDFMW01); and

• Hālawa Deep Well 2253-03 (HDMW2253-03).

The four consecutive quarterly monitoring events indicated that all COPC concentrations were 

below the EALs for samples collected at monitoring well RHMW04. In January 2010, 

concentrations of total petroleum hydrocarbons (TPH) diesel range organics (DRO) were above 

the EALs at OWDFMW01 and HDMW2253-03. As a result, quarterly monitoring was 

discontinued at RHMW04 and continued at the two remaining outside monitoring wells. This 

groundwater monitoring report presents the analytical results for samples collected on April 26, 

2012 at the two outside monitoring wells (OWDFMW01 and HDMW2253-03).

Laboratory analytical results indicate that all COPC concentrations during the April 2012 

monitoring event were below the DOH Drinking Water EALs with the exception of TPH-DRO 

at a concentration of 220 micrograms per liter (μg/L) in monitoring well OWDFMW01. 

TPH-DRO was detected at a concentration of 160 μg/L in monitoring well HDMW2253-03 

above the DOH Groundwater Gross Conatamination EAL but below the DOH Drinking Water 

EAL. Lead was detected at a concentration of 0.71 μg/L in monitoring well HDMW2253-03. 

Acetone was detected at an estimated concentration of 2.8 μg/L in monitoring well 

OWDFMW01. Benzene was detected at estimated concentrations of 0.71 μg/L in monitoring 

well OWDFMW01 and 0.20 μg/L in monitoring well HDMW2253-03. All other COPCs were 

not detected at or above the limits of detection (LODs) or the limits of quantitation (LOQs). 

LODs and LOQs were below the EALs for the majority of COPCs. In the case where an EAL

vi

for a specific COPC is less than the LOQ, it is generally acceptable to consider the LOQ in place 

of the EAL (DOH, 2009).

All COPC concentrations prior to the April 2012 monitoring event had been below EALs for at 

least the past six consecutive quarterly monitoring events dating back to October 2010. 

However, the April 2012 event showed TPH-DRO concentrations increase above the DOH 

Drinking Water EAL in monitoring well OWDFMW01 and above the DOH Gross 

Contamination EAL in both monitoring wells. In both of these TPH-DRO results, the analyst 

noted that the chromatogram of the samples were mainly non-diesel hydrocarbons within the 

boiling point range of diesel fuel. Massachusetts Department of Environmental Protection 

(MADEP) extractable petroleum hydrocarbon (EPH) analytical results in the October 2011 

monitoring event indicated that the detected hydrocarbons were most likely from non-petroleum 

sources. The reported TPH-DRO concentrations are not considered TPH-DRO, but 

non-petroleum hydrocarbons. The groundwater monitoring program results still indicate that 

concentrations of COPCs detected within the facility are not impacting the two outside 

monitoring wells. It is recommended that quarterly sampling remain the same and attention be 

paid to COPC concentrations at both monitoring wells for signs of contaminant migration.

Section 1 Introduction

This report presents the results of the April 2012 quarterly groundwater monitoring event at the 

two outside monitoring wells (OWDFMW01 and HDMW2253-03) at the RHSF, Joint Base 

Pearl Harbor-Hickam (JBPHH), O‘ahu, Hawai‘i (Figure 1-1). The groundwater monitoring was 

performed by Environet for the Department of the Navy (DON), Naval Facilities Engineering 

Command (NAVFAC) Hawai‘i under Environmental Technical Services, Contract Number 

N62742-08-D-1930, Contract Task Order (CTO) HC21.

This groundwater 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 groundwater 

monitoring well within the RHSF, specifically RHMW02, during the October 2008 groundwater 

monitoring event. The field activities performed for the April 2012 quarterly groundwater 

monitoring event were conducted in accordance with the procedures described 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 the RHSF. The groundwater monitoring was conducted to ensure that 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 implemented a groundwater monitoring program, which includes collecting 

quarterly groundwater samples from U.S. Navy Well 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 Well 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 Drinking Water EALs (DOH, 2009).

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 

monitoring events starting in August 2009 and ending in April 2010 at the following outside 

(non-tunnel) monitoring well locations:

• RHMW04; 

• Oily Waste Disposal Facility Monitoring Well 01 (OWDFMW01); and

• Hālawa Deep Well 2253-03 (HDMW2253-03).

The four consecutive quarterly monitoring events indicated that all 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 continued at the two remaining 

outside monitoring wells. This groundwater monitoring report presents the analytical results for 

samples collected on April 26, 2012 at the two outside monitoring 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 Hālawa Heights (Figure 1-1). Land adjacent to the north of the RHSF is occupied by 

the Hālawa 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 Well 

2254-01 is located approximately 3,000 feet downgradient (west) of the RHSF 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 the United States Naval 

Supply Systems Command (NAVSUP) Fleet Logistics Center (FLC) 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 from 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 

monitoring 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 aromatic 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 monitoring well (RHMW05) was installed within the lower access tunnel

between RHMW01 and RHMW2254-01. It was installed 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 Study 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. HDMW2253-03 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).

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 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).

1.2.4 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 toxicity 

EAL for these compounds was 240 μg/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 adopted more rigorous EALs 

of 4.7 μg/L for 1-methylnaphthalene and 24 μg/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 μg/L to 17 μg/L (DOH, 2009). 

Finally, the DOH Drinking Water EAL for TPH-DRO was increased from 100 μg/L to 210 μg/L, 

although the DOH Groundwater Gross Contamination EAL for TPH-DRO remains 100 μg/L.

Section 2 Monitoring Activities

Groundwater monitoring was conducted on April 26, 2012 in accordance with the site specific 

Work Plan (Environet, 2010). Field activities were documented in the field notebook (Appendix 

B).

2.1 Groundwater Gauging

Groundwater gauging measurements were taken at the two monitoring wells (OWDFMW01 and 

HDMW2253-03) prior 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 procedures described in Procedure I-C-3, Monitoring Well 

Sampling (DON, 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 monitoring 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 (total depth of 142.8 feet below top 

of casing (bTOC)) and HDMW2253-03 (large casing diameter of approximately 12 inches from 

the top of casing to approximately 50 feet below the groundwater surface, and the well is open 

[not cased] from approximately 50 feet 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 conductivity, dissolved oxygen, turbidity, and oxidation reduction 

potential. Readings were recorded on Groundwater Sampling Log data sheets (Appendix C).

2.2.2 Groundwater Sample Collection

Groundwater samples were collected from OWDFMW01 using four-inch and two-inch 

disposable bailers directly into laboratory provided, specially cleaned sample containers.

Groundwater samples were collected from HDMW2253-03 using a four-inch double stop 

disposable bailer directly into laboratory provided, specially cleaned sample containers. Due to 

the well construction characteristics of HDMW2253-03, 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. Dissolved lead samples collected from HDMW2253-03 required 

laboratory filtration due to the double stop bailer required to collect the sample.

2.2.3 Sample Management and Shipment

Each sample container sent to the laboratory was assigned a project-specific chain of custody 

identification 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-E, Record Keeping, Sample 

Labeling, and Chain-of-Custody (DON, 2007).

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, storage, 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 April 2012 groundwater monitoring event, two sets of primary groundwater samples, 

one set of duplicate groundwater samples and one set of quality control (QC) groundwater 

samples 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 procedures 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 10% of primary samples and analyzed for the same 

COPCs. 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 protocols 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 to the procedures 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; they 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 was 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® U-22 water quality meter) was conducted between monitoring locations according 

to the procedures described in Procedure I-F, Equipment Decontamination (DON, 2007). 

Decontamination water generated at monitoring well OWDFMW01 was disposed of in the 

RHSF’s lower tunnel oil/water separator sump.

2.7 Investigation-Derived Waste Management 

Investigation-derived waste (IDW) was managed in accordance with the procedures described in 

Procedure I-A-6, IDW Management (DON, 2007). The various potential waste streams included 

the following: 

 personal protective equipment (PPE), including: nitrile gloves, etc.; 

 liquids, including: equipment rinse water and purged groundwater; and

 disposable sampling equipment and supplies, including: bailers, poly sheeting, etc.

Equipment rinse water and purge water from OWDFMW01 was disposed of in the RHSF’s 

lower tunnel oil/water separator sump. Purge water from monitoring well HDMW2253-03 was 

disposed of in the surrounding grass (as directed by DLNR) since it was of drinking water 

quality. Spent PPE and non-contaminated sample jars and bottles (acid-free) were disposed of 

on a daily basis as solid waste.

Section 3 Groundwater Analytical Results

This section provides a summary of analytical results for groundwater samples collected from 

the two outside monitoring wells on April 26, 2012. Complete analytical laboratory reports are 

provided in Appendix D. 

3.1 Summary of Groundwater Analytical Results

OWDFMW01

TPH-DRO was detected in monitoring well OWDFMW01 at a concentration of 220 μg/L, which 

was above both the DOH Drinking Water EAL (210 μg/L) and Groundwater Gross 

Contamination EAL (100 μg/L) (Table 3-1). The analyst flagged the result noting that the 

chromatogram of this sample was mainly non-diesel hydrocarbons within the boiling point range 

of diesel fuel. The true TPH-DRO concentration is likely lower, but is reported at a higher 

concentration due to non-diesel hydrocarbons being detected by the analytical method.

Acetone was detected in monitoring well OWDFMW01 at an estimated concentration of 2.8 

μg/L, which is below the DOH Drinking Water EAL (22,000 μg/L) and Groundwater Gross 

Contamination EAL (20,000 μg/L). Benzene was detected in monitoring well OWDFMW01 at 

an estimated concentration of 0.71 μg/L, which is below the DOH Drinking Water EAL (5 μg/L) 

and Groundwater Gross Contamination EAL (170 μg/L).

No other COPCs were detected at or above the LODs and LOQs in monitoring well 

OWDFMW01. All LODs and LOQs were generally below the EALs. In the case where an EAL 

for a specific COPC is less than the LOQ, it is generally acceptable to consider the LOQ in place 

of the EAL (DOH, 2009).

HDMW2253-03

TPH-DRO was detected in monitoring well HDMW2253-03 at a concentration of 160 μg/L, 

which was below the DOH Drinking Water EAL (210 μg/L) and above the Groundwater Gross 

Contamination EAL (100 μg/L) (Table 3-1). The analyst flagged the result noting that the 

chromatogram of this sample was mainly non-diesel hydrocarbons within the boiling point range 

of diesel fuel. The true TPH-DRO concentration is likely lower, but is reported at a higher 

concentration due to non-diesel hydrocarbons being detected by the analytical method.

Lead was detected in monitoring well HDMW2253-03 at a concentration of 0.71 μg/L, which 

was below both the DOH Drinking Water EAL (15 μg/L) and Groundwater Gross 

Contamination EAL (5,000 μg/L). Benzene was detected in monitoring well HDMW2253-03 at 

an estimated concentration of 0.20 μg/L, which is below the DOH Drinking Water EAL (5 μg/L) 

and Groundwater Gross Contamination EAL (170 μg/L).

No other COPCs were detected at or above the LODs and LOQs in HDMW2253-03. All LODs 

and LOQs were generally below the EALs. In the case where an EAL for a specific 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 generally within the control limits. The relative 

percent difference (RPD) of field duplicates for all analytes were within the 50% criteria, except

for 1-methylnapthalene, 2-methylnapthalene, naphthalene, ethylbenzene, and lead. These

analyte concentrations ranged from not detected to very low concentrations below the EALs. 

Small variation in concentrations at very low (approaching decimal) levels will likely result in 

RPDs greater than 50%. The RPDs greater than 50% reported for this event would thus not have 

a significant effect on the overall data quality. The trip blank that accompanied the outside well 

samples did not contain detectable levels of any COPCs. Therefore, the data quality control 

results indicate that the data obtained for this monitoring 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, January 2011, 

April 2011, July 2011, October 2011, and January 2012 groundwater monitoring events. These 

constituents were also not detected above the EALs during this current groundwater monitoring 

event (April 2012).

TPH-DRO concentrations in OWDFMW01 significantly decreased from January 2010 (1,490 

μg/L) to April 2010 (288 μg/L). The concentrations of TPH-DRO at this monitoring well have 

decreased to non-detect in the previous six (October 2010, January 2011, April 2011, July 2011, 

October 2011, and January 2012) consecutive monitoring events (Table 3-3). During the April 

2012 monitoring event, the TPH-DRO concentration increased to a level above the EAL. 

However, the elevated concentration was mainly due to non-diesel hydrocarbons detected by the 

analytical method.

The concentrations of TPH-DRO at HDMW2253-03 decreased to non-detect for eight 

consecutive groundwater monitoring events from April 2010 to January 2012 (Table 3-3). 

During the April 2012 monitoring event, the TPH-DRO concentration increased slightly to a 

level below the EAL. However, the elevated concentration was mainly due to non-diesel 

hydrocarbons detected by the analytical method.

The October 2010 detection of acetone at an estimated concentration below the DOH Drinking 

Water EAL was the first at monitoring well OWDFMW01. Acetone was also detected at an 

estimated concentration in the trip blank sample during that same event. This suggested that 

acetone was introduced to the samples during transport to and from the laboratory and was not 

representative of groundwater at OWDFMW01. The concentration of acetone decreased to 

non-detect for five consecutive monitoring events from January 2011 to January 2012. Acetone 

was again detected at an estimated concentration at monitoring well OWDFMW01 in the April 

2012 monitoring event. The April 2012 detection marked the second event in which acetone was 

detected at an estimated concentration at the monitoring well. However, none of the trip blanks

for this monitoring event contained traces of the analyte, indicating that acetone was present at 

very low levels in the groundwater.

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 monitoring event or during April 2011. 

Estimated concentrations of lead below the DOH Drinking Water EAL were detected at both 

wells during the July 2011 and October 2011 monitoring events. Lead was detected at estimated 

concentrations below the DOH Drinking Water EAL in monitoring well HDMW2253-03 and in 

monitoring well OWDFMW01 in the January 2012 monitoring event. In the April 2012 

monitoring event, lead was detected at a concentration below the DOH Drinking Water EAL at 

HDMW2253-03 and was not detected at OWDFMW01. Lead concentrations in both monitoring 

wells have fluctuated below the DOH Drinking Water EAL. The concentrations, at which lead

has been detected, were very low to be of concern relative to the DOH Drinking Water EAL.

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 OWDFMW01 in April 2011; 

however, it was not detected in the July 2011 monitoring event. It was detected at an estimated 

concentration below the DOH Drinking Water EAL in HDMW2253-03 in the October 2011 

monitoring event. During the January 2012 monitoring event, benzene was detected at an 

estimated concentration below the Drinking Water EAL in monitoring well OWDFMW01. 

During the April 2012 monitoring event, benzene was detected at estimated concentrations 

below the Drinking Water EAL at both OWDFMW01 and HDMW2253-03 (Table 3-1). 

Benzene concentrations have fluctuated below the DOH Drinking Water EAL in monitoring 

wells HDMW2253-03 and OWDFMW01. The estimated concentrations, at which benzene has 

been detected, were very low to be of concern relative to the DOH Drinking Water EAL.

The April 2011 detections of xylenes and toluene below the DOH Drinking Water EALs in 

OWDFMW01 were the first at these monitoring wells. Xylenes and toluene were not detected in 

the July 2011, October 2011, January 2012, and April 2012 monitoring events (Table 3-1). 

Xylene and toluene concentrations have exhibited no trends in both monitoring wells. The April 

2011 xylene and toluene detections were estimated concentrations and were very low to be of 

concern relative to the DOH Drinking Water EALs.

Recommendations

4.1 Summary

TPH-DRO was detected at concentrations of 220 μg/L and 160 μg/L in monitoring wells 

OWDFMW01 and HDMW2253-03, respectively during the April 2012 groundwater monitoring 

event. The concentration detected at monitoring well OWDFMW01 was above both the DOH 

Drinking Water EAL (210 μg/L) and the DOH Groundwater Gross Contamination EAL (100 

μg/L). The concentration at monitoring well HDMW2253-03 was above the DOH Groundwater 

Gross Contamination EAL (100 μg/L). Lead was detected at a concentration of 0.71 μg/L in 

monitoring well HDMW2253-03, which was below the DOH Drinking Water EAL (5 μg/L) and 

the DOH Groundwater Gross Contamination EAL (5,000 μg/L). Acetone was detected at an 

estimated concentration of 2.8 μg/L in monitoring well OWDFMW01, which is below the DOH 

Drinking Water EAL (22,000 μg/L) and the DOH Gross Contamination EAL (20,000 μg/L). 

Benzene was detected at a estimated concentrations of 0.71 μg/L and 0.20 μg/L in monitoring 

wells OWDFMW01 and HDMW2253-03, respectively, which are below the DOH Drinking 

Water EAL (5 μg/L) and the DOH Groundwater Gross Contamination EAL (170 μg/L). No 

other COPCs were detected in monitoring wells HDMW2253-03 and OWDFMW01 during the 

April 2012 monitoring event.

4.2 Conclusions

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, January 2011, 

April 2011, July 2011, October 2011, and January 2012 groundwater monitoring events. PAHs 

and VOCs were also not detected above the EALs during the April 2012 monitoring event. The 

data continues to suggest that historically, TPH-DRO was the only COPC present in any notable 

quantity for the site.

TPH-DRO concentrations in OWDFMW01 significantly decreased from January 2010 (1,490 

μg/L) to April 2010 (288 μg/L) and were not detected in the subsequent six monitoring events 

(Table 3-3). The concentrations of TPH-DRO at HDMW2253-03 decreased from 322 μg/L in 

January 2010 to non-detectable levels for the eight consecutive quarterly monitoring events from 

April 2010 to January 2012. During the April 2012 monitoring event, the TPH-DRO 

concentration from OWDFMW01 increased to a level above the DOH Drinking Water EAL. 

TPH-DRO concentration in HDMW2253-03 also increased but to a level below the DOH 

Drinking Water EAL. The laboratory flagged both results noting that the chromatograms of the 

samples indicated mainly non-diesel hydrocarbons within the boiling point range of diesel fuel. 

MADEP EPH analytical results in the October 2011 monitoring event indicated that the detected 

hydrocarbons were most likely from non-petroleum sources. The true TPH-DRO concentrations

of the samples are likely lower, but are reported at higher concentrations as a result of non-diesel 

hydrocarbons detected by the analytical method.

The October 2010 detection of acetone at an estimated concentration below the DOH Drinking 

Water EAL was the first at monitoring well OWDFMW01. Acetone was also detected at an 

estimated concentration in the trip blank sample in October 2010. Acetone was not detected in 

the subsequent five monitoring events. This strongly suggested that acetone was introduced to 

the samples during transport to and from the laboratory. During the April 2012 monitoring 

event, acetone was again detected at an estimated concentration in monitoring well 

OWDFMW01 below the DOH Drinking Water EAL. None of the trip blanks for the April 2012 

monitoring event contained traces of the analyte, indicating that acetone was present at very low 

levels in the groundwater.

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 samples during the January 2011 monitoring event or during the April 2011 

monitoring event. Lead was detected at estimated concentrations below the DOH Drinking 

Water EAL at both monitoring wells during the July 2011 monitoring event. Lead was detected 

in monitoring well HDMW2253-03 at a concentration below the DOH Drinking Water EAL and 

in monitoring well OWDFMW01 at an estimated concentration below the DOH Drinking Water 

EAL during the October 2011 monitoring event. Lead was detected in monitoring wells

OWDFMW01 and HDMW2253-03 at estimated concentrations below the DOH Drinking Water 

EAL during the January 2012 monitoring event. Lead was detected in monitoring well 

HDMW2253-03 below the DOH Drinking Water EAL in the April 2012 monitoring event. Lead 

concentrations in both monitoring wells have fluctuated at very low levels below the DOH 

Drinking Water EAL.

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 OWDFMW01 in April 2011; 

however, it was not detected in the July 2011 and October 2011 monitoring events. It was 

detected at an estimated concentration below the DOH Drinking Water EAL in HDMW2253-03 

in the October 2011 monitoring event. Benzene was detected at an estimated concentration in 

monitoring well OWDFMW01 during the January 2012 monitoring event, which was below the 

Drinking Water EAL. Benzene was detected at estimated concentrations below the DOH 

Drinking Water EAL at monitoring wells OWDFMW01 and HDMW2253-03 during the April 

2012 monitoring event. Benzene concentrations have fluctuated in both monitoring wells at very 

low levels below the DOH Drinking Water EAL.

The April 2011 detections of xylenes and toluene in OWDFMW01 were the first at these 

monitoring wells. Xylenes and toluene were not detected in the July 2011, October 2011, 

January 2012, and April 2012 monitoring events. Xylene and toluene concentrations have 

exhibited no trends, and the April 2011 detections of both analytes were very low to be of 

concern relative the DOH Drinking Water EALs.

4.3 Recommendations

TPH-DRO was detected above the DOH Drinking Water EAL at monitoring well OWDFMW01 

during the April 2012 monitoring event. The TPH-DRO concentration detected above the EAL 

is believed to be the result of non-diesel hydrocarbons within the boiling point range of diesel

fuel being detected by the analytical method. MADEP EPH analytical results in the October 

2011 monitoring event indicated that the detected hydrocarbons were most likely from 

non-petroleum sources. It is recommended that quarterly sampling remain the same and 

attention be paid to concentration levels at both monitoring wells for signs of contaminant 

migration.
