# 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 Bu lk 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 fr om U.S. Navy Well 2254-01 (RHMW2254-01) and four groundwater monitoring wells (RHMW01, RHMW02, RHMW 03, 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 appr oximately 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 Ha wai‘i Department of H ealth (DOH) Drinking Water Environmental Action Levels (EALs) (DOH, 2009).
In response to increasing concentrations of ch emicals of potential concern (COPCs) in the groundwater monitoring wells w ithin 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) monitoring well locations:

 RHMW04;

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

 H ā lawa Deep Well 2253-03 (HDMW2253-03).
The four consecutive quarterly sampling events indicated all COPC conc entrations were below the EALs for samples collected at monitori ng well RHMW04. In Janua ry 2010 concentrations of total petroleum hydrocarbons (TPH) diesel ra nge 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 21, 2011 at the two outside monitoring wells (OWDFMW01 and HDMW2253-03).
Laboratory analytical results indicate that all COPC con centrations during the April 2011 groundwater sampling event were below the EALs. Benzene was detected in monitoring well HDMW2253-03 at an estimated concentr ation of 0.42 micrograms per liter ( μ g/L). Xylenes and toluene were detected in monitoring well OW DFMW01 at estimated concentrations of 0.39 μ g/L and 0.21 μ g/L, respectively. Benzene was also detected in the monitoring well OWDFMW01 duplicate sample at an estimated concentration of 0.29 μ g/L. Benzene was not detected in the OWDFMW01 primary sample. 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 the EALs. In the case where an EAL for a specifi c COPC is less than the LOQ, it is generally acceptable to consider the LOQ in place of th e EAL (DOH, 2009).

# Section 1 Introduction

This report presents the results of the April 20 11 quarterly groundwater m onitoring event at the two outside monitoring wells (OWDFMW01 a nd HDMW2253-03) at the RHSF, Pearl Harbor, O‘ahu, Hawai‘i (Figure 1-1). The groundwater monitoring was performed by Environet for the Department of the Navy (DON), Naval Facili ties Engineering Comma nd (NAVFAC) Hawai‘i under Environmental Technical Services, Cont ract Number N62742-08- D-1930, Contract Task Order Number HC14.
This groundwater monitoring event is consider ed supplemental to the quarterly groundwater monitoring program conducted with in the tunnels of the RHSF. This supplemental groundwater monitoring was conducted in response to increas ing concentrations of COPCs in a groundwater monitoring well within the RH SF, specifically RHMW02, during the October 2008 groundwater monitoring event. The field activities perf ormed for the April 2011 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 ev aluate the presence of COPCs in groundwater surrounding the RHSF. The groundwater monitori ng was conducted to ensure the DON remains in compliance with DOH UST re lease response requirements as described in Hawai‘i Administrative Rules (HAR) 11-281 S ubchapter 7, Release Response Action. 

# 1.2 Background

The U.S. Navy implemented a groundwater m onitoring program, which includes collecting quarterly groundwater samples from U.S. Navy Well 2254-01 (RHMW2254-01) and four groundwater monitoring wells (RHMW01, RH MW02, RHMW03, and RHMW05) installed in the RHSF lower access tunnel. The U.S. Navy We ll 2254-01 is located approximately 3,000 feet downgradient from the RHSF and provides approxima tely 24 percent of the potable water to the PHWS. The groundwater samples are analyzed fo r petroleum constituents and compared against DOH Drinking Water EALs (DOH, 2009).
In response to increasing con centrations of COPCs in the gr oundwater monitori ng wells within the facility (specifical ly 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:

 RHMW04;

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

 H ā lawa Deep Well 2253-03 (HDMW2253-03).Quarterly Groundwater Monitoring Report – Outside (Non-Tunnel) Wells Red Hill Bulk Fuel Storage Facility, Pearl Harbor, O‘ahu, Hawai‘i Section 1 Introduction June 2011



# 1-2 The four consecutive quarterly sampling events indicated all COPC conc entrations were below the EALs for samples collected at monitori ng well RHMW04. In Janua ry 2010 concentrations of TPH-DRO were above the EALs at OWDF MW01 and HDMW2253-03. As a result, quarterly monitoring was discontinued at RHMW04 and continued at the two remaining outside monitoring wells. This groundwater monitoring repor t presents the analytic al results for samples collected on April 21, 2011 at the two outside monitoring wells (OWDFMW01 and HDMW2253-03). The following sec tions 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, Hawa i‘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 busine sses. Land to the s outh 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 pot able water infiltratio n tunnel approximately 1,550 feet hydraulically downgrad ient from the RHSF (Environet, 2010). The U.S. Navy Well 2254-01 is located approximately 3,000 feet dow ngradient (west) of the RHSF and provides approximately 24 percent 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 Navy 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 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 prot ect their down-gradient drinking water resource associated with the U.S. Navy Well 2254-01.
By September 2005, the U.S. Navy had insta lled two more groundwater monitoring wells (RHMW02 and RHMW03) within the RHSF US T system, a groundwater monitoring well (RHMW04) north of the RHSF (adjacent to th e 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 ha ve 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 th e 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 – Outside (Non-Tunnel) Wells Red Hill Bulk Fuel Storage Facility, Pearl Harbor, O‘ahu, Hawai‘i Section 1 Introduction June 2011

Additionally, plans were made to sample thre e monitoring wells surr ounding and outside of RHSF: RHMW04, OWDFMW01, and HDMW2253-03 (F igure 1-1 and Table 1-1). RHMW04 was installed to evaluate gr oundwater within the basal aqui fer upgradient from RHSF. OWDFMW01 (originally known as MW08) was inst alled 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 geographi cally down-gradient of the USTs and U.S. Navy Well 2254-01. HDMW2253-03 is controlled by th e State of Hawai‘i Commission on Water Resource Management. HDMW2253-03 is locat ed between the RHSF and the municipal drinking water supply well whic h is operated by the City and County of Honolulu Board of Water Supply (H ā lawa Shaft Pumping Stati on 2354-01) (Figure 1-1).

# 1.2.3 UST Information The USTs were constructed in th e early 1940s. The tanks were c onstructed 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, av iation 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 approxima tely 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 me thylnaphthalenes. The drinking water toxicity EAL for these compounds was 240 μ g/L. This concentration pres umed that methylnaphthalenes were non-carcinogenic. Evidence th at 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 μ g/L for 1-methylnaphthalene and 24 μ g/L for 2-methylnaphthale ne, corresponding to a residential tap water scenario, and a one in a million cancer risk (DOH, 2009).
Also, the drinking water EAL for na phthalene was incr eased 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 Groundw ater Gross Contamination EAL for TPH-DRO remains 100 μ g/L.Quarterly Groundwater Monitoring Report – Outside (Non-Tunnel) Wells Red Hill Bulk Fuel Storage Facility, Pearl Harbor, O‘ahu, Hawai‘i Section 1 Introduction June 2011

# 2-1 

# Section 2 Monitoring Activities

Groundwater monitoring was conducted on April 21, 2011 in accordance with the site specific Work Plan (Environet, 2010). Field activities were documente d in the field notebook (Appendix A). 

# 2.1 Groundwater Gauging

Groundwater gauging measurements were collected at the two monitoring wells (OWDFMW01 and HDMW2253-03) prior to purging and sample co llection. 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 Natura l Resources (DLNR) employee prior to well purging (Table 1-1). 

# 2.2 Groundwater Sampling
Groundwater samples were collected from the tw o 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 and HDMW 2253-03 (large casing diameter of 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 feet below TOC to 1,575 feet below TOC), three we ll casing volumes were not purged prior to sampling. Instead, water was purged using dispos able bailers until three or more successive water quality parameter measurements had stabilized within 10 percent. A Horiba ® 

# U-22 multi-parameter water quality meter was used to measure hydrogen activity (pH), temperature, specific conductivity, dissolved oxy gen, turbidity, and oxidation reducti on potential. At least six readings were recorded on Groundwater Sampling Log data sheets (Appendix B).



# 2.2.2 Groundwater Sample Collection Groundwater samples were collected from OWDFMW01 and HDMW2253-03 using four and two-inch disposable bailers. Groundwater samples were collect ed directly in to laboratory provided, specially cleaned, sample containers already containing the appropriate preservatives (i.e., nitric acid for dissolved lead analysis). Th e dissolved lead samples we re filtered in the field and placed in polyethylene bottles cont aining the appropriate preservative.



# 2.2.3 Sample Management and Shipment Each sample container sent to the laboratory was assigned a project-sp ecific 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).Quarterly Groundwater Monitoring Report – Outside (Non-Tunnel) Wells Red Hill Bulk Fuel Storage Facilit y, Pearl Harbor, O‘ahu, Hawai‘i Section 2 Monitoring Activities June 2011



# 2-2 Following sample collection and labeling, the sa mple 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 unde r standard chain of custody protocol and documentation from collection to delivery to th e laboratory. Sample handling, storage, and transport were performed according to the re quirements described in Procedure III-F, Sample Handling, Storage, and Shipping (DON, 2007). 

# 2.3 Analytical Program
During the April 2011 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 presente d and discussed in Section 3. 

# 2.4 Field Quality Control Samples
Field QC procedures were followed to ensure viab ility and integrity of sample analytical data. Field duplicates were collected according to th e procedures described in Procedure III-B, Field QC Samples (Water, Soil) (DON, 2007) and the Work Plan (E nvironet, 2010). Field duplicate samples were collected at a minimum of 10 per cent of primary samples and analyzed for the same contaminants. Field rinsate samples were not required since disposab le 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 spik e 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 fiel d sample; they are not separate samples, but a special designation of an existing sample. Labor atory 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 pe rformed to ensure data quality, to prevent cross contamination, and to prevent the potential introduction of contamin ants into previously un-impacted areas. Decontamination of monito ring 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 monitori ng well OWDFMW01 was disposed of in the RHSF’s lower tunnel oil/ water separator sump.Quarterly Groundwater Monitoring Report – Outside (Non-Tunnel) Wells Red Hill Bulk Fuel Storage Facilit y, Pearl Harbor, O‘ahu, Hawai‘i Section 2 Monitoring Activities June 2011



# 2-3 

# 2.7 Investigation-Derived Waste (IDW) Management
IDW was managed in accordance with the pr ocedures described in Procedure I-A-6, IDW Management (DON, 2007). The various potential wa ste streams included the following:

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

 liquids including: equipment rins e water and purged groundwater; and

Purge water from monitoring well HDMW2253-03 was disposed of in the surrounding grass (as direct ed 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.Quarterly Groundwater Monitoring Report – Outside (Non-Tunnel) Wells Red Hill Bulk Fuel Storage Facilit y, Pearl Harbor, O‘ahu, Hawai‘i Section 2 Monitoring Activities June 2011

# 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 21, 2011. Complete analytical laboratory reports are provided in Appendix C. 

# 3.1 Summary of Groundwater Analytical Results

OWDFMW01 Benzene (only in the duplicate sample), xylenes and toluene were detected in OWDFMW01 at estimated concentrations of 0.29 μ g/L, 0.39 μ g/L, and 0.21 μ g/L which are below both the Drinking Water EAL (5 μ g/L for benzene, 10,000 μ g/L for xylenes, and 1,000 μ g/L for toluene) and the Gross Contamination EAL (170 μ g/L for benzene, 20 μ g/L for xylenes, and 40 μ g/L for toluene) (Table 3-1, Table 3-2).

All other COPCs were not detected at or above the LODs and LOQs in 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 accept able to consider the LOQ in place of the EAL (DOH, 2009).

HDMW2253-03
Benzene was detected in HDMW2253-03 at an estimated concentration of 0.42 μ g/L which is below both the Drinking Water EAL (5 μ g/L) and the Gross C ontamination EAL (170 μ g/L) (Table 3-1).

All other COPCs were not 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 accept able 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) of field duplicates for all analytes were within the 50 percent criteria. The trip blank that accompanied the outside well samples did not contain dete ctable levels of any COPCs. The data quality control results indicate that th e data obtained for this monitoring event are suitable for their intended use (Table 3-2).
Benzene, xylenes, and toluene were not detected in the laboratory blank samples (Appendix C). 

# 3.2 Groundwater Contaminant Trend

Concentrations of PAHs and VOCs were previ ously not detected above the EALs during the August 2009, October 2009, January 2010, April 2010, July 2010, October 2010, and JanuaryQuarterly Groundwater Monitoring Report – Outside (Non-Tunnel) Wells Red Hill Bulk Fuel Storage Facilit y, Pearl Harbor, O‘ahu, Hawai‘i Section 3 Groundwater Analytical Results June 2011



# 3-2 2011 groundwater monitoring events. These constituents were also not detected above the EALs during this groundwater monitoring event.

TPH-DRO concentrations in OWDFMW01 have significantly decreased from January 2010 (1,490 μ g/L) to April 2010 (288 μ g/L) and to non-detect in October 2010, January 2011, and April 2011 (Table 3-1 and Table 3-3). TPH-DRO c oncentrations at this well are decreasing.

The concentrations of TPH-DRO at HDMW2253- 03 have decreased to non-detect for five consecutive events (Table 3-3). TPH-DRO c oncentrations at this well are decreasing.

The October 2010 detection of acetone at an es timated concentration below the DOH Drinking Water EAL was the first at monitoring well OWDF MW01. Acetone was also detected at an estimated concentration in the tr ip blank sample. This suggested that acetone was introduced to the samples during transport to and from the labo ratory, and is not repres entative of groundwater at OWDFMW01. The previous conclu sion that acetone is not repr esentative of groundwater at OWDFMW01 is confirmed in the January 2011 sa mpling event and during this sampling event as acetone was not detected in any of the samples collected.

The October 2010 detections of lead at conc entrations below the DOH Drinking Water EAL were the first at these two monitoring we lls (OWDFMW01 and HDMW2253-03). Lead was not detected in any of the samples in the Janua ry 2011 sampling event an d during this sampling event. This suggests that the October 2010 detection of lead was an anomaly.
The January 2011 detection of benzene at an es timated concentration be low the DOH Drinking Water EAL in OWDFMW01 was the first at this m onitoring well. Benzene was detected at an estimated concentration in the duplicate sample collected from OWDFMW01 during this sampling event.
The April 2011 detections of xylenes and toluene in OWDFMW01 and benzene in HDMW2253-03 at estimated concentrations 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, April 2011

# Section 4 Summary, Conclusions, and Recommendations

4.1 Summary

Benzene was detected at an estimated concentration of 0.42 μ g/L in HDMW2253-03 during this groundwater monitoring event. This concentr ation is below the DOH Drinking Water EAL (5 μ g/L) and the DOH Gross Contamination EAL (170 μ g/L). No other COPCs were detected in HDMW2253-03 during the April 20 11 groundwater sampling event.
Xylenes and toluene were detected at estimated concentrations of 0.39 μ g/L and 0.21 μ g/L, respectively in OWDFMW01 during this groundwat er monitoring event. Benzene was also detected in OWDFMW01 duplicate sample at an estimated concentration of 0.29 μ g/L. Benzene was not detected in the OWDFMW01 primary sa mple. These estimated concentrations are below the DOH Drinking Water EALs (5 μ g/L for benzene, 10,000 μ g/L for xylenes, and 1,000
μ g/L for toluene) and the DOH Gross Contamination EALs (170 μ g/L for benzene, 20 μ g/L for xylenes, and 40 μ g/L for toluene). No other COPCs we re detected in OWDFMW01 during the April 2011 groundwater sampling event. 

# 4.2 Conclusions
Concentrations of PAHs and VOCs were previ ously not detected above the EALs during the August 2009, October 2009, January 2010, April 2010, July 2010, October 2010, and January 2011 groundwater monitoring events. These constituents were also 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 notab le quantity for the site.

TPH-DRO concentrations in OWDFMW01 have significantly decreased from January 2010 (1,490 μ g/L) to April 2010 (288 μ g/L) and to non-detect in October 2010, January, and April 2011 (Table 3-1 and Table 3-3). The concen trations of TPH-DRO at HDMW2253-03 have decreased to non-detect for five consecutive events. The data suggest that TPH-DRO concentrations are atte nuating naturally at th e two outside wells.

The October 2010 detection of acetone at an es timated concentration below the DOH Drinking Water EAL was the first at monitoring well OWDFMW01. Acetone was not detected in the January 2011 sampling event nor during this sa mpling event. This confirms 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 th e 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 sampling event nor during this sampling event. This confirms the lead detection in October 2010 was an anomaly.
The January 2011 detection of benzene at an es timated concentration be low the DOH Drinking Water EAL in OWDFMW01 was the first at this monitoring well. Benzene was again detectedQuarterly Groundwater Monitoring Report – Outside (Non-Tunnel) Wells Red Hill Bulk Fuel Storage Facilit y, Pearl Harbor, O‘ahu, Hawai‘i Section 4 Summary, Conclusions, and Recommendations June 2011



# 4-2 only in the duplicate sample from OWDFMW01 at an estimated concentration below the DOH Drinking Water EAL during th e April 2011 sampling event.
The April 2011 detections of xylenes and toluene in OWDFMW01 and benzene in HDMW2253-03 at estimated concentrations below the DOH Drinking Water EALs were the first at these monitoring wells. 

# 4.3 Recommendations

Based on the results of the field observations and analytical testing, conti nuation of the quarterly groundwater monitoring of OWDFMW01 and HD MW2253-03 is recommended to monitor the presence of COPCs in the groundwater surrounding the RHSF.Quarterly Groundwater Monitoring Report – Outside (Non-Tunnel) Wells Red Hill Bulk Fuel Storage Facilit y, Pearl Harbor, O‘ahu, Hawai‘i Section 5 References June 2011
