### EXECUTIVE SUMMARY

This quarterly groundwater monitoring report presents the results of the third quarter 2013 groundwater sampling conducted on July 22 and 23, 2013, at the Red Hill Bulk Fuel Storage Facility [RHSF], Joint Base Pearl Harbor-Hickam [JBPHH], Hawaii. The RHSF is located in Halawa Heights on the Island of Oahu. There are 18 active and 2 inactive Underground Storage Tanks [USTs] located at the RHSF. The State of Hawaii Department of Health [DOH] Facility Identification [ID] number is 9-102271. The DOH Release ID numbers are 990051, 010011, and

020028.

The groundwater sampling was conducted as part of the long-term groundwater and soil vapor monitoring at the RHSF, under Naval Facilities Engineering Command [NAVFAC] Contract Number N62742-12-D-1853. The sampling was conducted in accordance with the approved Work Plan [WP]/Sampling and Analysis Pl an [SAP] prepared by Environmental Science International [ESI].

On July 22 and 23, 2013, ESI personnel collected groundwater samples from five monitoring wells at the RHSF (wells RHMW01, RHMW02, RHMW03, RHMW05, and RHMW2254-01). A summary of the analytical results is provided below.

 RHMW01 – Total Petroleum Hydrocarbons as di esel [TPH-d] (99 micrograms per liter [μg/L]) and naphthalene (0.048 μg/L) were detected. None of the chemical constituents analyzed for were detected at concentrations above the DOH Environmental Action Levels [EALs].

 RHMW02 – TPH-d (2,500 μg/L), Total Petroleum Hydrocarbons as gasoline [TPH-g] (55 μg/L), acenaphthene (0.52 μg/L), fluorene (0.23 μg/L), 1-methylnaphthalene (21 μg/L), 2-methylnaphthalene (9.1 μg/L), naphthalene (73 μg/L), ethylbenzene (0.17 μg/L), and xylenes (0.45 μg/L), and dissolved lead (0.135 μg/L) were detected. TPH-d, 1-methylnaphthalene, and naphthalene were detected at concentrations above the DOH EALs for both drinking water toxicity and gross contamination.

 RHMW03 – TPH-d (48 μg/L) and naphthalene (0.064 μg/L) were detected. None of the chemical constituents analyzed for were detected at concentrations above the DOH EALs.

 RHMW05 – Naphthalene (0.033 μg/L) was detected. None of the chemical constituents analyzed for were detected at concentrations above the DOH EALs.

 RHMW2254-01 – Total lead (0.300 μg/L) and naphthalene (0.099 μg/L) were detected. None of the chemical constituents analyzed for were detected at concentrations above the

DOH EALs.

Since the wells were last sampled (April 2013), groundwater contaminant concentrations in four wells (RHMW01, RHMW03, RHMW05, and RHMW2254-01) remained at low concentrationsContract No. N62742-12-D-1853 Contract Task Order 0002

### and did not change significantly, or were not detected. Only the groundwater samples from

RHMW02 showed concentrations of contaminants of potential concern [COPCs] exceeding the

DOH EALs.

TPH-d concentrations detected in well RHMW01 during the last sampling (April 2013) event increased above the DOH EALs for both drinking wa ter toxicity and gross contamination for the first time since February 2012. During this round of sampling, TPH-d was detected at a concentration just below the DOH EAL for gross contamination, but well below the drinking

DOH EALs.

2-Methylnaphthalene concentrations detected in the primary and duplicate samples collected from well RHMW02 during this sampling event decreased to concentrations below the DOH EALs. TPH-d concentrations detected in the samples collected from well RHMW02 decreased, but still exceeded the EALs and were consistent with previous analytical data. This decrease is consistent with a decrease in TPH-d concentration in well RHMW01 during this event.

With the exception of 2-methylnaphthalene, concentration of COPCs in well RHMW02 have not changed significantly. TPH-d, 1-methylnaphthalene, 2-methylnaphthalene, and naphthalene concentrations have been decreasing since groundwater monitoring was initiated in 2005. This is the first sampling event since July 2012 that 2-methylnaphthalene concentrations have been detected below both the drinking water toxicity and gross contamination DOH EALs.

Based on the results of the groundwater monitoring, continuing the groundwater monitoring program at the RHSF is recommended. If TPH-d concentrations in well RHMW02 significantly increase, the monitoring frequency should be increased to monthly in accordance with the

RHSF Groundwater Protection Plan.Contract No. N62742-12-D-1853 Contract Task Order 0002

### SECTION 1 – INTRODUCTION

This quarterly groundwater monitoring report presents the results of the third quarter 2013 groundwater sampling conducted on July 22 and 23, 2013, at the RHSF, JBPHH. The RHSF is located in Halawa Heights on the Island of Oahu. The purpose of the sampling is to (1) assess the condition of groundwater beneath the RHSF with respect to chemical constituents associated with jet fuel propellant and marine diesel fuel, and (2) to ensure the Navy remains in compliance with DOH UST release response requirements as described in Hawaii Administrative Rules 11-281 Subchapter 7, Release Response Action. The DOH Facility ID
number for the RHSF is 9-102271. The DOH Release ID numbers are 990051, 010011, and

020028.

The groundwater sampling was conducted as part of the long-term groundwater and soil vapor monitoring at the RHSF, under NAVFAC Contract Number N62742-12-D-1853. The sampling was conducted in accordance with the appr oved WP/SAP prepared by ESI (ESI, 2012).

### D ESCRIPTION



### The RHSF is located on federal government land (zoned F1- Military and Federal), located in Halawa Heights, approximately 2.5 miles northeast of Pearl Harbor (Figure 1). It is located on a low ridge on the western edge of the Koolau Mountain Range that divides Halawa Valley from Moanalua Valley. The RHSF is bordered on the north by Halawa Correctional Facility and private businesses, on the west by the United Stat es of America [U.S.] Coast Guard reservation, on the south by residential neighborhoods, and on the east by Moanalua Valley. A quarry is located less than a quarter mile away to the northwest. The RHSF occupies 144 acres of land and the majority of the site is at an elevati on of approximately 200 to 500 feet above mean sea

level.

The RHSF contains 18 active and 2 inactive USTs that are operated by Naval Supply Systems Command Fleet Logistics Center [NAVSUP FLC] Pearl Harbor (formerly Fleet and Industrial Supply Center). Each UST has a capacity of approximately 12.5 million gallons. The RHSF is located approximately 100 feet above the basal aquifer. The USTs contain Jet Fuel Propellant-5 [JP-5], Jet Fuel Propellant-8 [JP-8], and Marine Diesel Fuel [F-76]. The current status of the

USTs are summarized in Table 1.1.

Five groundwater monitoring wells (wells RHMW01, RHMW02, RHMW03, RHMW05, and RHMW2254-01) are located within the RHSF lower access tunnel (Figure 2). Two groundwater monitoring wells (wells HDMW2253-03 and OWDFMW01) are located outside of the RHSF tunnel system. Monitoring data for the two wells located outside the tunnel are included in a
separate report.

Monitoring wells RHMW01, RHMW02, RHMW03, and RHMW05 are located inside the underground tunnels. Monitoring well RHMW2254-01 is located inside the infiltration gallery of the Department of the Navy [DON] Well 2254-01. The DON Well 2254-01 is locatedContract No. N62742-12-D-1853 Contract Task Order 0002

### 1.2 P HYSICAL 

### S ETTING



### Climatological conditions in the area of the RHS F consist of warm to moderate temperatures and low to moderate rainfall. The RHSF is leeward of the prevailing northeasterly trade winds. The average annual precipitation is approximately 40 inches, which occurs mainly between November and April (State of Hawaii Department of Land and Natural Resources [DLNR], 1986). Annual pan evaporation is approximately 75 inches (DLNR, 1985). Average temperatures range from the low 60’s to high 80’s (degrees Fahrenheit) (Atlas of Hawaii, 1983).

Oahu consists of the eroded remnants of two shield volcanoes, Waianae and Koolau. The RHSF is located on the southwest flank of the Koolau volcanic shield. Lavas erupted during the shield-building phase of the volcano belong to the Koolau Volcanic Series (Stearns and Vaksvik, 1935). Following formation of the Koolau shield, a long period of volcanic quiescence occurred, during which the shield was deeply eroded. Following this erosional period, eruptive activity resumed. Lavas and pyroclastic material erupted during this period belong to the HonoluluContract No. N62742-12-D-1853 Contract Task Order 0002

### Volcanic Series (Stearns and Vaksvik, 1935).

In the immediate area of the RHSF, Koolau Volcanic Series lavas dominate, although there are consolidated and unconsolidated non-calcareous deposits in the vicinity that consist of alluvium generated during erosion of the Koolau volcanic shield. South-southwest of the RHSF, and in isolated exposures to the west, are pyroclas tic deposits formed during eruptions from three
Honolulu Volcanic Series vents, Salt Lake, Aliamanu, and Makalapa (Stearns and Vaksvik, 1935). Based on established geology and records of the drilled wells (Stearns and Vaksvik, 1938), the RHSF is underlain by Koolau Volcanic Series basalts. The area of the RHSF is

classified as Rock Land , where 25-90% of the land surface is covered by exposed rock and there are only shallow soils (Foote, et al., 1972).

Groundwater in Hawaii exists in two principal types of aquifers. The first and most important type, in terms of drinking water resources, is the basal aquifer. The basal aquifer exists as a lens of fresh water floating on and displacing seawater within the pore spaces, fractures, and voids of the basalt that forms the underlying mass of each Hawaiian island. In parts of Oahu, groundwater in the basal aquifer is confined by the overlying caprock and is under pressure. Waters that flow freely to the surface from wells that tap the basal aquifer are referred to as

artesian

.

The second type of aquifer is the caprock aquifer, which consists of various kinds of unconfined and semi-confined groundwater. Commonly, the caprock consists of a thick sequence of nearly impermeable clays, coral, and basalt, which s eparates the caprock aquifer from the basal aquifer. The impermeable nature of these materials and the artesian nature of the basal aquifer severely restrict the downward migration of groundwater from the upper caprock aquifer. In the area of the RHSF, there is no discernible caprock.

Groundwater in the area of the RHSF is part of the Waimalu Aquifer System of the Pearl Harbor Aquifer Sector. The aquifer is classified as a basal, unconfined, flank-type; and is currently used as a drinking water source. The aquifer is considered fresh with less than 250 milligrams per liter of chloride and is considered an irreplaceable resource with a high vulnerability to contamination (Mink and Lau, 1990).

The nearest drinking water supply well is DON Well 2254-01, located in the infiltration gallery within the RHSF. The DON Well 2254-01 is located approximately 2,400 feet downgradient of the USTs (Figure 2).

1.3 B ACKGROUND



### The RHSF was constructed by the U.S. Government in the early 1940s. Twenty USTs and a series of tunnels were constructed. The USTs were constructed of steel and they currently contain JP-5, JP-8, and F-76. Several tanks in the past have stored DON special fuel oil, DON distillate, aviation gasoline, and motor gasoline (Environet, 2010). The fueling system is a selfcontained underground unit that was installed into native rock comprised primarily of basalt withContract No. N62742-12-D-1853 Contract Task Order 0002

### some interbedded tuffs and breccias (Environet, 2010). Each UST measures approximately 245 feet in height and 100 feet in diameter. The upper domes of the tanks lie at a depth varying between 100 feet and 200 feet below ground surface [bgs].

In 1998, Earth Tech conducted a Phase II remedial investigation/feasibility study for the Oily Waste Disposal Facility located within the RHSF. The study involved installing well OWDFMW01 (which was originally MW08) (Earth Tech, 1999).

In February 2001, the DON installed groundwater monitoring well RHMW01 to monitor for contamination in the basal aquifer beneath the RHSF. Well RHMW01 was installed approximately 100 feet below grade within the lower access tunnel. The depth to water was measured at 86 feet below grade at the time of the well completion. In February 2001, a groundwater sample was collected from the well. Total Petroleum Hydrocarbons [TPH] and lead were detected in the samples. Lead was detected at a concentration above the DOH EAL (The Environmental Company, Inc. [TEC], 2009; DOH, 2000).

In 2005, the RHSF groundwater monitoring program was initiated. It involved routine groundwater sampling of wells RHMW01 and RHMW2254-01. Samples were collected in February, June, September, and December of 2005. Lead was detected at concentrations above the DOH EAL in samples collected in February and June. The samples collected in February and June were not filtered prior to analysis, whereas the samples collected in September and December were filtered prior to analysis. Since the samples collected in February and June were not filtered prior to analysis, the lead results were not considered appropriate for a risk assessment (TEC, 2008).

Between June and September 2005, TEC installed three groundwater monitoring wells (wells RHMW02, RHMW03, and RHMW04) within the RHSF (TEC, 2008). Well RHMW04 was installed upgradient of the USTs to provide background geochemistry information for water moving through the basal aquifer beneath the RHSF. Wells RHMW02 and RHMW03 were installed approximately 125 feet below grade within the RHSF lower tunnel and well RHMW04 was installed to a depth of approximately 300 feet bgs outside of the RHSF tunnels. In September 2005, groundwater samples were collected from the three newly installed groundwater monitoring wells (wells RHMW02, RHMW03, and RHMW04) along with the two existing wells (wells RHMW01 and RHMW2254-01). The COPCs with concentrations exceeding

DOH EALs are summarized below.

 RHMW01 – TPH-d was detected at concentrations above the DOH EAL.

 RHMW02 – TPH-g, TPH-d, naphthalene, trichloroethylene, 1-methylnaphthalene, and 2-methylnaphthalene were detected at concentrations above the DOH EALs.

 RHMW03 – TPH-d was detected at concentrations above the DOH EAL.

In 2006, TEC installed dedicated sampling pumps in the five wells (wells RHWM01, RHWM02, RHMW03, RHWM04,and RHMW2254-01). In July and December of 2006, groundwaterContract No. N62742-12-D-1853 Contract Task Order 0002

### SECTION 2 – GROUNDWATER SAMPLING

On July 22 and 23, 2013, ESI personnel collected groundwater samples from five monitoring wells at the RHSF (wells RHMW01, RHMW02, RHMW03, RHMW05, and RHMW2254-01). The samples were collected in accordance with DOH UST release response requirements (DOH, 2000) and the RHSF Groundwater Protection Plan (TEC, 2008). Prior to purging and sampling, the depth to groundwater and the depth to the bottoms of the wells were measured using a Geotech oil/water interface probe. No meas urable product, sheen, or petroleum hydrocarbon odor was detected in any of the wells with the exception of RHMW02. A slight petroleum hydrocarbon odor was noticed when collecting groundwater samples from RHMW02.

2.1 G ROUNDWATER 

### S AMPLING



### Prior to collecting groundwater samples, the monitoring wells were purged of water in the well casings. Each well contains a dedicated bladder pump which was used to purge the well and to collect samples. To operate the pump, a portable air compressor with an in-line filter was connected to a QED MP50 MicroPurge Basics Controller box, which was then connected to the pump. The compressor was turned on to power the pump and the controller was used to adjust the pumping rate to less than one liter of water per minute.

Water quality parameters were monitored on a periodic basis during well purging. The water quality parameters that were measured incl uded hydrogen activity [pH], temperature, conductivity, dissolved oxygen, and oxidation reduction potential. The water quality parameters were evaluated to assess whether the natural characteristics of the aquifer formation water were present within the monitoring wells before collecting the samples. At least four readings were collected during the purging process. Purging was considered complete when at least three consecutive water quality measurements stabilized within approximately 10%. The readings were recorded on groundwater monitoring logs. The groundwater monitoring logs are included in Appendix A. In addition, field notes were taken to document the sampling event. The field notes are included in Appendix B.

When the water quality parameters stabilized, groundwater samples were collected from the wells using the bladder pumps. The groundwater samples were collected no more than two hours after purging was completed to decrease groundwater interaction with the monitoring well casing and atmosphere. Prior to collecting the sample, the water level in the monitoring wells was measured and recorded to ensure that water was not drawn down. The groundwater samples were collected at flow rates of approximately 0.10 to 0.33 liters per minute. Samples collected for dissolved lead analysis were filtered in the field using 0.45 micron filters.

### EPA Method 6020, and total lead using EPA Method 200.8. The sample collected from well RHMW2254-01 was analyzed for total lead (unfiltered) as DON Well 2254-01 is a drinking water supply well. The analytical results are summarized below and in Table 2.1. A copy of the laboratory report is included in Appendix C.

 RHMW01 – TPH-d (99 μg/L) and naphthalene (0.048 μg/L) were detected. None of the chemical constituents analyzed for were detected at concentrations above the DOH EALs.

 RHMW02 – TPH-d (2,500 μg/L), TPH-g (55 μg/L), acenaphthene (0.52 μg/L), fluorene (0.23 μg/L), 1-methylnaphthalene (21 μg/L), 2-methylnaphthalene (9.1 μg/L), naphthalene (73 μg/L), ethylbenzene (0.17 μg/L), xylenes (0.45 μg/L), and dissolved lead (0.135 μg/L) were detected. TPH-d, 1-methylnaphthalene, and naphthalene were detected at concentrations above the DOH EALs for both drinking water toxicity and gross

contamination.

 RHMW03 – TPH-d (48 μg/L) and naphthalene (0.064 μg/L) were detected. None of the chemical constituents analyzed for were detected at concentrations above the DOH EALs.

 RHMW05 – Naphthalene (0.033 μg/L) was detected. None of the chemical constituents analyzed for were detected at concentrations above the DOH EALs.

 RHMW2254-01 – Total lead (0.300 μg/L) and naphthalene (0.099 μg/L) were detected. None of the chemical constituents analyzed for were detected at concentrations above the

### Historical groundwater contaminant concentra tion trends of COPCs that exceeded the DOH EALs are presented in Appendix D. A summary of groundwater contaminant trends is provided

below.

 RHMW01 – COPCs detected during this round of quarterly sampling were consistent with historical data. TPH-d has historically been detected at concentrations above the DOH EAL for both drinking water toxicity and gross contamination. TPH-d concentrations showed a decreasing trend from 1,500 μg/L in February 2005 to 79 μg/L in February 2013. The TPH-d concentration increased to 340 μg/L in April 2013, but decreased to 99 μg/L during this sampling event below both DOH EALs.

 RHMW02 – TPH-d, TPH-g, 1-methylnaphthalene, 2-methylnaphthalene, and naphthalene have historically been detected at concentrations above the DOH EALs. TPH-d concentrations during the last several rounds of sampling have shown an increasing trend, but concentrations have been lower than the high of 5,420 μg/L in October 2008 and decreased slightly during this sampling event. 1-Methylnaphthalene and naphthalene concentrations remained consistent with the last event in April 2013.

### 2-Methylnaphthalene dropped below the DOH EALs. TPH-g concentrations remained consistent and below the DOH EALs during the last two rounds of sampling, indicating the high concentrations detected in October 2012 and January 2013 may be anomalous.

 RHMW03 – COPCs detected during this round of quarterly sampling were consistent with historical data. TPH-d has historically been detected at concentrations above the DOH
EALs; however, it has not been detected at concentrations above the DOH EALs since

October 2010.

 RHMW05 – COPCs detected during this round of quarterly sampling were consistent with historical data. TPH-d has historically been detected at concentrations above the DOH EAL for both drinking water toxicity and gross contamination; however, it has not been detected at concentrations above the DOH EALs since January 2010.

 RHMW2254-01 – COPCs detected during this round of quarterly sampling were consistent with historical data. TPH-d was detected at a concentration above the DOH EAL for gross contamination in January 2008; however, it has not been detected at concentrations above

the DOH EALs since then.

Historical groundwater contaminants concentrations above the DOH EALs for both drinking water toxicity and gross contamination are presented in Appendix D.

### SECTION 3 – DATA QUALITY ASSESSMENT

A data quality assessment, which consists of a review of the overall groundwater sample collection and analysis process, was performed in order to determine whether the analytical data generated meets the quality objectives for the project. The data quality assessment was performed in accordance with the approved WP/SAP prepared by ESI (ESI, 2012). The field quality control program consisted of standardized sample collection and management procedures, and the collection of field duplicate samples, matrix spike samples, and trip blank samples. The laboratory quality assurance program consisted of the use of standard analytical methods and the preparation and analyses of Matrix Spike [MS]/Matrix Spike Duplicate [MSD] samples, surrogate spikes, blanks, and Laboratory Control Samples [LCSs].

3.1 Data Validation and Assessment

The objective of data validation is to provide dat a of known quality for project decisions. Data quality is judged in terms of Precision, A ccuracy, Representativeness, Completeness, Comparability, and Sensitivity [PARCCS]. A number of factors may affect the quality of data, including: sample collection methods, sample analysis methods, and adherence to established procedures for sample collection, preservation, management, shipment, and analysis.

Precision

Precision is defined as the reproducibility of rep licate measurements. Precision is evaluated by Relative Percentage Difference [RPD] of field duplicates and laboratory LCS/Laboratory Control Sample Duplicates [LCSDs] or MS/MSD results. Field duplicate and MS/MSD samples were collected at a rate of approximately 10% of primary samples. Field duplicates were sent to the laboratory along with the primary samples.

The RPDs of primary and field duplicate samples are provided in Table 3.1. With the exception of 2-methylnaphthalene, all duplicate RPDs are less than 20% (below 50% as recommended in the NAVFAC Project Procedures Manual [DON 2007]), and therefore, the data precision is considered acceptable. The concentration of 2-methylnaphthalene detected in the primary sample ES029 (9.1 μg/L) was close to the DOH EAL for gross contamination (10 μg/L). However, the concentration detected in the field duplicate sample ES030 (6.6 μg/L) was well below the DOH EALs. Because of this and the fact that 1-methylnaphthalene and TPH-d were detected in sample ES029 at concentrations exceeding the DOH EALs, the high RPD is unlikely to affect data usability.

The RPD of the MS/MSD results for 2-methylnaphthalene was above the acceptable maximum of 20%. This is in line with the field duplicate sample RPD results. Also, the high sample concentration in the MS/MSD samples relative to the spike amounts, likely resulted in the low precision of the recovery. All other RPDs for MS/MSD and LCS/LCSD pairs were within the
acceptance range.Contract No. N62742-12-D-1853 Contract Task Order 0002

### Accuracy

Accuracy is defined as the degree of conformity of a measurement to a standard or true value. Accuracy is evaluated through measurement of the percent recovery of an analyte in a reference standard or spiked sample. Accuracy limits for surrogates, laboratory control spike, MS, and MSD samples are established by the individual laboratory.

Between July 2006 and July 2010, naphthalene was analyzed for by both EPA Methods 8260B and 8270C, and both results were reported. In September 2005 and in all data beginning in October 2010, only results using EPA Method 8270C were reported. Naphthalene has historically only been detected at concentrations above the DOH EALs in well RHMW02. In this well, concentrations of naphthalene detected in each sample by EPA Method 8260B were generally two to three times higher than those detected by EPA Method 8270C. We assume this is due to the better preservation of VOCs associated with the use of EPA Method 8260B. This suggests that the naphthalene results provided by EPA Method 8270C may be biased low. Since October 2012, naphthalene concentrations in RHMW02 have exceeded DOH EALs for both gross contamination and drinking water to xicity. The naphthalene concentration detected in July 2012 (17 μg/L) was equal to the DOH EAL for drinking water (17 μg/L) but below the DOH EAL for gross contamination (21 μg/L); it is possible that accounting for the low bias, the actual naphthalene concentration detected during this event exceeded both EALs. Naphthalene concentrations between April 2011 and April 2012 were all an order of magnitude below both EALs, and it is unlikely that decisions based on these data are significantly affected by the low

bias

Results for TPH-d in samples ES028, ES029, ES030, and ES031 were flagged “HD.” The laboratory indicated a mismatch between the calibration standard and the TPH-d chromatographic profile. Mismatches of this type are not uncommon. The chromatograms are not part of the standard laboratory package and were not reviewed by ESI.

All surrogate spike recoveries for analyzed constituents were within acceptable percent recovery limits. All LCS recoveries were within recovery limits. Naphthalene, 2-methylnaphthalene and 1-methylnaphthalene concentrations for ES029, the primary sample on which the MS/MSD were performed, we re significantly higher than the added spike concentration, which prevented an accurate evaluation of the MS/MSD recovery for these analytes.

All other MS and MSD recoveries were within acceptable recovery limits, therefore, the data accuracy for this monitoring event is considered acceptable.

Representativeness

Representativeness is the degree that data accurately and precisely represents a characteristic of a population, parameter variations at a sampling point, or an environmental condition. Representativeness was achieved by conducting sampling in compliance with the sample collection procedures described in the WP/SAP (ESI, 2012).Contract No. N62742-12-D-1853 Contract Task Order 0002

Red Hill LTM, 3Q2013 Status Report 3-3 September 2013

### Representativeness is also evaluated via compli ance with established sample holding time and sample preservation, and through the analysis of blank samples, including method blank and trip blank samples. The hold time for VOC/TPH-g analysis for samples ES028, ES029, ES030, and ES031 were exceeded by one day. According to Standard Operative Procedure II-B, Standard and Full Data Validation Procedure for GC/MS Volatile Organics by SW-846 8260B , in the Navy Project Procedure Manual, the hold time exceedance only affects aromatic volatiles (benzene, toluene, ethylbenzene, and xylene [BTEX] compounds and the BTEX portion of TPH-g) (DoN 2007). A footnote has been added to the affected results in Tables 2-1 and 3-1 to indicate a possible low bias; however, due to the low BTEX concentrations detected during this event and in previous events, this is unlikely to affect project decisions. It is unlikely that the samples were significantly affected by this delay in analysis and therefore, the groundwater sample data are considered representative of the groundwater quality on site. All other sample holding time and sample preservation were in compliance with EPA guidance.

For this sampling event, one trip blank was collected. TPH-g (21 μg/L) was detected in the trip blank at a concentration below the limit of detection [LOD]. TPH-g was detected in samples ES029 and ES030. In ES029 and ES030, the TPH-g is likely attributable to the gasoline-range organics associated with the high concentrations of TPH-d and is consistent with TPH-g concentrations detected during the last sampling event. However, concentrations of TPH-g detected in the samples were no more than approximately half of the EAL, and it is unlikely the contamination in the trip blank significantly affects data usability. Therefore, the groundwater sample data are considered representative of the groundwater quality on site. The quality control results are provided in Table 3.1.

Completeness

Completeness is defined as the overall percentage of valid analytical results (including estimated results) compared to the total number of analytical results reported by the analytical laboratory. No data were rejected for this project, and therefore the completeness goal for this project (90%), was successfully met.

Comparability

Comparability expresses the confidence with which one data set can be compared to another data set. Comparability can be related to accuracy and precision because these quantities are measures of data reliability. Data, with acce ptable precision and accuracy, are considered comparable if collection techniques, analytical procedures, methods and reporting are equivalent.

Between July 2006 and July 2010, naphthalene was analyzed for by both EPA Methods 8260B and 8270C, and both results were reported. In September 2005 and in all data beginning in October 2010, only results using EPA Method 8270C were reported. In general, EPA Method 8260B resulted in higher, and as discussed above likely more accurate, results than EPA Method 8270C. However, for the sake of comparability with results from recent events, EPAContract No. N62742-12-D-1853 Contract Task Order 0002

Red Hill LTM, 3Q2013 Status Report 3-4 September 2013
Inside Tunnel Wells



### Method 8270C was used for naphthalene analysis in this event. Consequently, the low bias associated with Method 8270C should be considered when making project decisions.

All TPH-g data through July 2010 were analyzed by EPA Method 8015; beginning in October
2010, EPA Method 8260B was used. There was no event where both methods were used; consequently, there is no way to directly compare the results obtained by method and to assess potential bias. However, there is no reason to believe that using either method should bias the data, and the TPH-g data for all events should be comparable.

Other than the naphthalene bias discussed above, no issues with comparability were identified. The results are considered comparable within this data set and with the data collected from recent sampling events.

Sensitivity

The limits of quantitation [LOQs] are established by the laboratory based on the LODs or
instrument detection limits, historical data, and EPA limits established for the methods. The LOQs for samples may require adjustment due to matrix interference or if high levels of target analytes necessitate dilution before analysis. Matrix interference and sample dilutions have the effect of increasing the LOQs. Laboratory LODs and LOQs for several analytes differed from the LODs and LOQs in the WP/SAP because the laboratory updates them quarterly and in some cases, dilution was necessary due to the presence of high concentrations of analytes.

LODs and LOQs for several analytes were greater than the DOH EALs (as stated in the WP/SAP), and therefore it is not possible to determine whether the analytes are present at concentrations greater than or equal to the DOH EALs. As suggested by the DOH Technical Guidance Manual, when the LOQ exceeds the DOH EAL, the project action level will be the LOQ for these analytes. The affected analytes for this monitoring event are 1,1-dichloroethane, 1,2,3-trichloropropane, 1,2-dibromo-3-chloropropane, 1,2-dibromoethane, 1,2-dichloroethane,1,3-dichloropropene, bromodichloromethane, bromomethane, chloromethane, dibromochloromethane, hexachlorobutadiene, methylene chloride, 1,1,1,2-tetrachloroethane, 1,1,2,2- tetrachloroethane, benzo[a]anthracene, benzo[g,h,i]perylene, benzo[b]fluoranthene, benzo[k]fluoranthene, dibenzo[a,h]anthracene, and ideno[1,2,3-cd]pyrene.

3.2 Data Assessment and Usability Conclusions

The PARCCS criteria were evaluated, and with a few exceptions, all criteria were met. TPH-g contamination in the trip blank shows that there may be a slight high bias in the TPH-g groundwater sample results; however, it is unlikely that this affects the usability of the data for making project decisions. Other analytes that had issues causing concentrations to be biased high or low were either not detected in groundwater samples, or were detected at concentrations well below project action levels. The data assessment concludes that all data generated during this event are usable for the intended purpose.Contract No. N62742-12-D-1853Contract Task Order 0002Red Hill LTM, 3Q2013 Status Report3-5September 2013Inside Tunnel WellsTABLE 3.1Quality Control Results for Groundwater Sampling (July 22, 2013)Red Hill Bulk Fuel Storage FacilityJuly 2013 Quarterly Monitoring ReportMethodChemical ConstituentDOH EALsRHMW02 (ES029)RHMW02 (ES030) (DUP)RPD Duplicate(%)ES TripDrinking WaterToxicityGrossContaminationResultQLOQLODDLResultQLOQLODDLResultQLOQLODDLEPA 8015B TPH-d 190 1002,500HD 50 20 152,600HD 50 20 15 4 - - - - -EPA 8260B TPH-g 100 10055150 30 1361150 30 13 10 21 J 50 30 13EPA 8270CAcenaphthene 370 20 0.52 0.2 0.05 0.021 0.51 0.2 0.05 0.021 2 - - - - -Acenaphthylene 240 2,000 N.D.

### SECTION 4 – SUMMARY, CONCLUSIONS, AND RECOMMENDATIONS

On July 22 and 23, 2013, ESI personnel collected groundwater samples from five monitoring wells at the RHSF (wells RHMW01, RHMW02, RHMW03, RHMW05, and RHMW2254-01).

The groundwater sampling was conducted as part of the long-term groundwater and soil vapor monitoring at the RHSF, under NAVFAC Contract Number N62742-12-D-1853. The sampling was conducted in accordance with the approv ed WP/SAP prepared by ESI. A summary of the analytical results is provided below.

 RHMW01 – TPH-d (99 μg/L) and naphthalene (0.048 μg/L) were detected. None of the chemical constituents analyzed for were detected at concentrations above the DOH EALs.

 RHMW02 – TPH-d (2,500 μg/L), TPH-g (55 μg/L), acenaphthene (0.52 μg/L), fluorene (0.23 μg/L), 1-methylnaphthalene (21 μg/L), 2-methylnaphthalene (9.1 μg/L), naphthalene (73 μg/L), ethylbenzene (0.17 μg/L), xylenes (0.45 μg/L), and dissolved lead (0.135 μg/L) were detected. TPH-d, 1-methylnaphthalene, and naphthalene were detected at concentrations above the DOH EALs for both drinking water toxicity and gross

contamination.

 RHMW03 – TPH-d (48 μg/L) and naphthalene (0.064 μg/L) were detected. None of the chemical constituents analyzed for were detected at concentrations above the DOH EALs.

 RHMW05 – Naphthalene (0.033 μg/L) was detected. None of the chemical constituents analyzed for were detected at concentrations above the DOH EALs.

 RHMW2254-01 – Total lead (0.300 μg/L) and naphthalene (0.099 μg/L) were detected. None of the chemical constituents analyzed for were detected at concentrations above the

DOH EALs.

Groundwater Contaminant Trends

 RHMW01 – COPCs detected during this round of quarterly sampling were consistent with historical data. TPH-d has historically been detected at concentrations above the DOH EAL for both drinking water toxicity and gross contamination. TPH-d concentrations showed a decreasing trend from 1,500 μg/L in February 2005 to 79 μg/L in February 2013. The TPH-d concentration increased to 340 μg/L in April 2013, but decreased to 99 μg/L during this sampling event below both DOH EALs.

 RHMW02 – TPH-d, TPH-g, 1-methylnaphthalene, 2-methylnaphthalene, and naphthalene have historically been detected at concentrations above the DOH EALs. TPH-d concentrations during the last several rounds of sampling have shown an increasing trend, but concentrations have been lower than the high of 5,420 μg/L in October 2008 and decreased slightly during this sampling event. 1-Methylnaphthalene concentrationsContract No. N62742-12-D-1853 Contract Task Order 0002

Red Hill LTM, 3Q2013 Status Report
Inside Tunnel Wells 4-2 September 2013 

### remained consistent with the last event in April 2013. TPH-g concentrations remained below the DOH EALs during the last two rounds of sampling, indicating the high concentrations detected in October 2012 and January 2013 may be anomalous. Naphthalene concentrations decreased slightly since the last event in April 2013.

 RHMW03 – COPCs detected during this round of quarterly sampling were consistent with historical data. TPH-d has historically been detected at concentrations above the DOH
EALs; however, it has not been detected at concentrations above the DOH EALs since

October 2010.

 RHMW05 – COPCs detected during this round of quarterly sampling were consistent with historical data. TPH-d has historically been detected at concentrations above the DOH EAL for both drinking water toxicity and gross contamination; however, it has not been detected at concentrations above the DOH EALs since January 2010.

 RHMW2254-01 – COPCs detected during this round of quarterly sampling were consistent with historical data. TPH-d was detected at a concentration above the DOH EAL for gross contamination in January 2008; however, it has not been detected at concentrations above

the DOH EALs since then.

Conclusions and Recommendations

Since the wells were last sampled (April 2013), groundwater contaminant concentrations in four wells (RHMW01, RHMW03, RHMW05, and RHMW2254-01) remained at low concentrations and did not change significantly, or were not detected. Only the groundwater samples from RHMW02 had concentrations of COPCs exceeding the DOH EALs.

TPH-d concentrations detected in well RHMW01 during the last sampling (April 2013) event increased above the DOH EALs for both drinking wa ter toxicity and gross contamination for the first time since February 2012. During this round of sampling, TPH-d was detected at a concentration just below the DOH EAL for gross contamination, but well below the drinking

DOH EALs.

2-Methylnaphthalene concentrations detected in the primary and duplicate samples collected from well RHMW02 during this sampling event decreased to concentrations below the DOH EALs. TPH-d concentrations detected in the samples collected from well RHMW02 decreased, but still exceeded the EALs and were consistent with previous analytical data. This decrease is consistent with a decrease in TPH-d concentration in well RHMW01 during this event.

With the exception of 2-methylnaphthalene, concentration of COPCs in well RHMW02 have not changed significantly. TPH-d, 1-methylnaphthalene, 2-methylnaphthalene, and naphthalene concentrations have been decreasing since groundwater monitoring was initiated in 2005. This is the first sampling event since July 2012 that 2-methylnaphthalene concentrations have been detected below both the drinking water toxicity and gross contamination DOH EALs.Contract No. N62742-12-D-1853 Contract Task Order 0002

### Based on the results of the groundwater monitoring, continuing the groundwater monitoring program at the RHSF is recommended. If TPH-d concentrations in well RHMW02 significantly increase, the monitoring frequency should be increased to monthly in accordance with the

RHSF Groundwater Protection Plan.Contract No. N62742-12-D-1853 Contract Task Order 0002
