SECTION I - INTRODUCTION
The following subsections describe the system and the authority and purpose of the inspection.
Inspection Objectives
From June 3 through June 7, 2024, the United States Environmental Protection Agency (EPA) and the EPA's
contract inspectors from ERG (referred to as the EPA inspection team) conducted an announced Compliance
Evaluation Inspection under Section 1445 of the Safe Drinking Water Act (SDWA), 42 U.S.C. §300j-4, of the
NAVFAC's Joint Base Pearl Harbor-Hickam PWS (HI0000360) (System or JBPHH). The purpose of the inspection
was to evaluate the System's compliance with the SDWA and the National Primary Drinking Water Regulations
(NPDWR) found in Title 40 of the Code of Federal Regulations (40 C.F.R.) Part 141 and the EPA Administrative
Consent Order the System signed on June 2, 2023. The inspection also included a special sampling event to
help EPA assess the System's compliance with the SDWA as well as other applicable regulations, including the
Hawaii Department of Health Administrative Rules. The scope of the inspection was an onsite review of the
water source, treatment facilities, equipment, operation, maintenance, and monitoring compliance of a PWS
to evaluate the adequacy of the PWS, its sources and operations, and the distribution of safe drinking water.
Personnel from the Hawaii Department of Health (HDOH) accompanied the EPA inspection team. While HDOH
has assumed primary enforcement responsibility to implement the SDWA PWSS program for the state of
Hawaii, EPA still retains inspection and enforcement authority in Hawaii.
EPA notified Rear Admiral Steve Barnett of the System via letter delivered by electronic mail that an inspection
would be conducted on June 3 through 7, 2024. The Notice of Inspection is provided in Appendix B.
Information regarding the reason and statutory authority for the inspection was discussed with System
representatives during the inspection.
This report is based on information supplied by the System representatives through interviews and written
statements, observations made by the EPA inspection team, and records and reports maintained by the
System. As part of the inspection process, the EPA inspection team made direct observations, took
photographs, took measurements, and reviewed relevant documents. Information gathered from EPA, State,
and public records prior to, during, or after the onsite inspection are referenced in this report as applicable.
System Description
According to the Safe Drinking Water Information System (SDWIS) database, the System serves a population of
65,230 people. It is a community water system as defined by 40 C.F.R., Part 141, Subpart A. The EPA inspection
team confirmed the population served with System representatives during the inspection process via
conversations and document review. The System is a groundwater system that serves military installations and
military housing through unmetered connections.
The NAVFAC operates and manages four PWSs (JBPHH, Camp Stover, Naval Computer and
Telecommunications Area Master Station Pacific, and Pacific Missile Range Facility Kauai) in the state of
Hawaii. System representatives informed the EPA inspection team that NAVFAC operates and maintains its
four PWSs primarily with the same personnel, Supervisory Control and Data Acquisition System (SCADA),
emergency response equipment, and other shared resources. Due to the NAVFAC's management practice,
some system information such as the amount of operational hours expended solely on JBPHH could not be
confirmed. The PWSs are not interconnected to supply JBPHH with either an emergency or routine water
source. The System has emergency interconnections with the Honolulu Board of Water Supply (BWS) and
System representatives estimated that those interconnections may provide up to 3 million gallons per day
(MGD) if activated.

Joint Base Pearl Harbor-Hickam
Inspection Dates: June 3-7, 2024
The System employs water treatment operators who have various responsibilities across the PWSs that
NAVFAC operates and manages. The HDOH provided a list of three Class 4 distribution system operators who
are registered with HDOH to operate the System, The EPA inspection team requested but did not receive an
organizational chart of the System personnel or a list of certified operators with operator information prior to
the end of the inspection. Post-inspection, the System provided a list of certified operators, of which four were
at the Class 4 level - the document did not go into detail on what responsibilities the operators have within
the operation. Refer to Appendix D for a log of documents the EPA inspection team requested before and
during the inspection.
The System's source water is three groundwater sources from a system of tunnels and shafts.
System
draws the Waiawa Shaft supply always operating^^^^^^^H to
meet water demand. Water demand at the time of the inspection was approximately
representatives stated that water demand can routinely fluctuate from approximatelyHtoj^^^H. The
System disinfects with sodium hypochlorite and fluoridates with sodium fluoride before the entry point to the
distribution system.sources include the Aiea Halawa Shaft and the Red Hill Shaft, which were also
equipped to disinfect and fluoridate when in operation, These sources were not in production at the time of
the inspection and were physically disconnected from the distribution system. The System removed the
groundwater supplies from production in 2021 due to concern of fuel contamination in the water supply.
The System was the sole water supply to the Aliamanu Military Reservation (AMR), which is a consecutive
water system (PWS HI0000337).
The System has approximatelv|^^^^J of water mains, a series ofjj^^ booster pump stations, anc
finished water storage ground tanks/reservoirs to distribute the water supply throughout the varied
topography of the area to maintain an approximate average ofB pounds per square inch (psi) of water
pressure within the distribution system. A newly installedmain was in service at
the time of the inspection and of the^^H reservoirs were in service. |
SECTION II- INSPECTION ACTIVITIES
The following subsections describe the inspection activities completed by the EPA inspection team. Appendix
A includes photographs taken during this inspection that support the report findings
Opening Conference
The EPA inspection team arrived at the System, located at 0800 HST on June
3, 2024, for the inspection. Refer to Appendix C for the opening conference sign-in sheet. Personnel from the
United States Department of the Army (Army) were also present as the EPA inspection team was conducting
an inspection of AMR and JBPHH concurrently throughout the week, Mike McFadden and Christopher Chen
presented credentials to Captain Robert Kleinman, P.E., NAVFAC Public Works Officer, and informed him that
this was an EPA Region 9 inspection to determine compliance with the Primacy Agency requirements, the
NPDWR, and the SDWA.

Inspection Dates: June 3-7, 2024
The opening conference included a discussion of System details; active and inactive sources; treatment;
distribution system; staffing; operations and SCADA systems; maintenance and asset management; and
emergency response planning. In addition, the opening conference also included discussion on EPA's plan to
collect drinking water samples at multiple locations, including the three JBPHH sources, AMR's entry point to
the distribution system (EPDS), and a few residences and childcare centers within the JBPHH and AMR
distribution systems.
The EPA inspection team collected sampling at all sample sites for a subset of analytes listed in Navy's
Extended Drinking Water Monitoring (EDWM) Plan1, and are listed below (see Appendix G for analytical
results):
• 1,2 dibromoethane (commonly known as ethylene dibromide)
• Benzene
• Ethyl benzene
• Toluene
• 1,2,4-trimethylbenzene
• 1,3,5-trimethylbenzene
• Xylenes (total)
• M,p-xylenes
• o-xylenes
• JP-5 as combined TPH - gasoline range
• JP-5 as combined TPH - diesel and oil ranges
• Copper
• Lead
• Beryllium
• Mercury
• 1-methylnaphthalene
• 2-methylnaphthalene
• Naphthalene
• Benzo[a]pyrene
In addition, PFAS samples were collected at the locations below. The PFAS samples were tested for over 70
different PFAS analytes (see Appendix G for a full list of analytes and results from the three shafts).
Waiawa Shaft
Red Hill Shaft
Aiea Halawa Shaft
- AMR EPDS
Navy raised four concerns regarding EPA's collection of PFAS samples that they believed exceeded EPA's
authority:
1. The collection of PFAS samples at the two^^^H sources (Red Hill Shaft and Aiea Halawa Shaft);

2. Alleged that PFAS sampling at AMR was unprecedented as AMR was part of the distribution system2;
3. Raised concerns about the extensive PFAS sampling relying on a modified EPA method 537.1; and
4. PFAS sampling beyond the 29 PFAS analytes listed within EPA's Unregulated Contaminant Monitoring
Rule.
These concerns were annotated directly onto the Notice of Inspection for JBPHH. The EPA inspection team
acknowledged the concerns and its intent to move forward with the inspection and sampling plan under the
authority granted by the SDWA; any concerns may also be communicated to EPA's leadership. While Navy and
Army disagreed with the PFAS sampling, both clearly stated they would not impede the collection of any
samples.
Physical Assets Inspected
The EPA inspection team conducted an array of field activities to evaluate the drinking water system, including
the assets listed here in the remainder of Section II. The physical inspection occurred over five consecutive
days.
The following descriptions are based on information provided to the EPA inspection team by the System and
observations made during the inspection. Observations are described in Section III of this report.
Halawa Reservoirs S-l and S-2
The two reservoirs share a fenced perimeter and
e EPA inspection team observed the location of the Halawa Reservoir S-2's isolation valves, one
below-grade and one above-grade, that System representatives stated were closed to isolate and drain the
reservoir. The System representatives operated a spigot on the reservoir side of one isolation valve and no
water flowed from it. The EPA inspection team observed from ground level a considerable amount of
corrosion and a failed coating on the reservoir but did not fully evaluate the structure or the interior^^J
(Photograph
Photograph 2).
The coating on the sidewalls of the Halawa S-l Reservoir had failed, exposing a substantial percentage of the
reservoir sidewall primer layer and steel to the weather, and resulting corrosion has impacted the sidewall
structural integrity (Photograph 3). The sidewall has evidence of dozens of exterior patch repairs (Photograph
4 and Photograph 5). The sidewall also has unrepaired areas of corrosion with metal loss in multiple locations
that ranged in size from 1 to 6 inches in diameter. The reservoir base is corroded with metal loss around the
perimeter (Photograph 6, Photograph 7, and Photograph 8).
The Halawa S-l Reservoir had a locked shoebox-style hatch access that was gasketed to prevent
contamination. The EPA inspection team observed isolated vertical corrosion streaks above the water line that
2 Note: Army collected samples for six PFAS analytes under the Unregulated Contaminant Monitoring Rule (UCMR) 3 and collected
samples for 29 PFAS analytes in 2023 under UCMR 5. Results were non-detect.

indicated some areas of corrosion on interior roof features (Photograph 9). The EPA inspection team observed
that the water was clear to the floor of the reservoir and there was a sediment layer on the floor of the
reservoir. The amount of sediment could not be estimated due to limited visibility through the access hatch
(Photograph 10). The roof had evidence of some exterior patch repairs and unrepaired areas of corrosion that
ranged in size from 1 to 6 inches in diameter (Photograph 11 and Photograph 12). Multiple locations along the
roof perimeter had evidence of ponded water with corrosion at some weld seams (Photograph 13).
The Halawa S-l Reservoir vent was intact with fine mesh screening. The System representatives stated that
the overflows of both reservoirs at the site combine to one below-grade access pit. The overflow was flush to
the floor of the access pit with fine mesh screening. The access pit contained the drain outfall and the storm
water outlet of the access pit, according to System representatives (Photograph 14).
Aiea Halawa Shaft and Halawa Booster Pump Station
;m representatives operated a shaft pump during the inspection to provide
water for sampling.I
and was rerouted with temporary hose connections to an offsite area to discharge onto the surface when the
shaft pumps are periodically operated (Photograph 15 and Photograph 16). System representatives described
line-shaft
pumps were in place and System representatives statedthat^operational. When operated,
the System uses^J pump at less than the permitted water allocation and the shaft capacity to reduce the
risk of introducing elevated chloride levels to the supply.
The EPA inspection team observed a garden hose connected to a shaft pump air relief discharge that was not
screened and resting on the floor (Photograph 17). A penetration in the pump room floor above the shaft
supply had a plug inserted that was loose around its perimeter and had a cable inserted through it, potentially
not sealed from contaminants (Photograph 18). A shaft site tube and access point had corroded electrical
conduit connections near floor level with openings to the shaft not sealed from contaminants (Photograph 19
and Photograph 20).
The onsite water treatment facilities have and disinfection and
fluoridation equipment in place. Chemical feed systems were out of operation since the source is considered
non-potable.
The EPA inspection team observed a free chlorine analyzer in the sodium hypochlorite chemical building that
tested sample flow from the distribution system, not from the Aiea Halawa Shaft entry point. The value on the
analyzer read 0.54 milligrams per liter (mg/L). The EPA inspection team tested a grab sample from the same
sample point for comparison that resulted in a value of 0.66 mg/L.
Although the sodium hypochlorite feed was out of service, System representatives stated that it could be
reactivated within a day if needed. The EPA inspection team observed corrosion on a chemical system pump in
the chemical feed area (Photograph 21).

Red Hill Shaft and Red Hill Booster Pump Station
The Red Hill Shaft groundwater source was taken out of operation in late 2021 due to concern of fuel
contamination in the water supply and was not in operation as a water supply source at the time of the
inspection. System representatives operated a shaft pump during the inspection to provide water for
sampling. was physically disconnected from the System's distribution system and was

The shaft is designed pumps of^^^^Jcapacity each. System representatives
described efforts to troubleshoot vibration issues and stated that^^^^^J was fully operational, Hwas
physically disconnected to accommodate the emergency GAC effluent connection, and the remaining^®
were offline for an ongoing repair project.
The EPA inspection team observed an open access through the floor of the pumproom above the shaft supply
that was not sealed from contaminants. The opening is typically sealed via a water tight cover; however, it was
accessible for ongoing well recovery and remediation-related efforts. The immediate area is adjacent to the
sodium fluoride chemical feed area and active construction activity (Photograph 23 and Photograph 24). All
treatment tanks for sodium fluoride application had been taken out of service but^^J retained solution
and/or chemical (Photograph 25 and Photograph 26).
The Booster Pump is
with two split-case horizontal pumps that pump to the Red Hill Tanks. System representatives stated that a
distribution system operator controls the pumps remotely to maintain water level in the tanks above^^^|.
Red Hill Tanks S-316 and S-685
The tanks on this site are bolted steel tanks with a capacity of
housing units. The tanks
The Red Hill Tank S-316 had vegetation up to 3 feet tall within the fenced area at the bottom of the access
steps and sporadic vegetation elsewhere around the tank foundation (Photograph 27 and Photograph 28). The
roof had a locked and gasketed access hatch. The vent was screened with fine mesh. The interior floor was not
visible to assess if a sediment layer had accumulated. The overflow discharged outside of the fenced area and
was not visible from the tanks without scaling down a short embankment. The overflow flapper valve had a
gasket and closed completely; it did not have an internal fine mesh screen.
The Red Hill Tank S-685 had vegetation at the bottom of the access steps and sporadic vegetation elsewhere
around the tank foundation (Photograph 29, Photograph 30, and Photograph 31). The tank base had a gap
between the metal bottom flange and the concrete foundation that was not sealed from water or vegetation
(Photograph 31). The roof had a locked and gasketed access hatch. The vent was screened with fine mesh. The
interior floor was not visible to assess if a sediment layer had collected. The overflow discharged outside of
the fenced area and was not visible from the tanks without scaling down a short embankment. The overflow
flapper valve had a gasket and closed completely; it did not have an internal fine mesh screen.

The EPA inspection team observed that the sodium hypochlorite disinfection system consisted of one 330-
gallon tote stored outside the day tank room (exposed to direct sunlight), two 330-gallon totes with
containment serving as day tanks in the day tank room, four 330-gallon totes in a chemical storage room
under cover, and a separate chemical application room with two chemical feed pumps and accessory
equipment (Photograph 32 and Photograph 33). System representatives explained that the tote exposed to
direct sunlight was temporarily stored there for transfer and would be moved shortly after. System
representatives stated that operators record the chlorine level in the day tank daily, refill the day tanks from
the totes in the chemical storage area as needed, relocate any exterior 330-gallon totes to the chemical
storage area as space allows, and reorder sodium hypochlorite at an approximate rate of^^^^-gallon totes
per week. The System has an inline chlorine analyzer^^^^^^^^^^^^^^^^^^J and displayed a result
of 0.61 mg/L at the time of the inspection.
The EPA inspection team observed that the sodium fluoride disinfection system consisted of approximately 70
50-1 b sodium fluoride bags stored on a pallet in the center of the chemical feed room,^| chemical saturator
tanks, and^| chemical feed pumps with accessory equipment. The EPA inspection team observed that the
sodium fluoride chemical feed suction lines were suspended unsupported across a walkway at risk of being
displaced by personnel (Photograph 47). System representatives stated that operators refill the saturator unit
based upon observations of the fluoride residual. The System has an inline

The Camp Smith Tank S-326 is similar to Camp Smith Tank S-325 in location, type, construction, and size but
according to System representatives has not been inspected since approximately May 2013 (Photograph 34).
The tank capacity is^^^^fgallons. The roof had an access hatch and vent in a locked rooftop shelter. The
aluminum access cover was flush to the floor level, loosely attached, and not gasketed (Photograph 35 and
Photograph 36). The vent was screened with fine mesh. The EPA inspection team observed that the interior
floor had a sediment layer covering all visible areas, but the depth could not be determined. The overflow
discharged to ground level and was not downturned. The overflow flapper valve was counterweighted and
had a seal but did not close completely and had no internal fine mesh screen (Photograph 37). When the
overflow flapper was lifted for inspection, a gecko or lizard ran out of the overflow.
The Camp Smith Tank S-327 was labeled S-684 but referred to by System personnel also as S-327 (Photograph
38). The System information states that the tank capacity is^^^J gallons but System personnel stated that
the maximum volume it can be filled to is^^^J gallons due to the elevation of the tank (Photograph 39).
The roof had a locked and gasketed access hatch and a vent that was screened with fine mesh. The EPA
inspection team observed that the center safety climb rail on the access ladder extended above the top ladder
rung, which restricted access to the roof (Photograph 40). Tree limbs extended over the aluminum roof of the
tank (Photograph 41). The roof perimeter had collected several inches of debris from the trees and had
vegetation growing from it (Photograph 42). The EPA inspection team observed that sediment covered the
floor of the tank and was estimated to be at least 1 inch deep (Photograph 43 and Photograph 44). The
sidewall of the glass-fused to steel tank had weathered, chalky, cracking, and missing caulk sealant at the
bolted panel junctions (Photograph 45). The interior overflow discharged below grade within a grated
stormwater pit. The discharge end was at the bottom of the pit and had a flapper valve that was not accessible
for further evaluation at the time of the inspection (Photograph 46).
Cybersecurity Review
The EPA inspection team conducted a cybersecurity review with System staff. Refer to Appendix C for Sign-In
Sheet related to the review. Any observations associated with this review were discussed onsite and are not
included in this report for security reasons.
Records Review
Records were reviewed before, during, or after the onsite inspection. Appendix D lists documents requested
or reviewed during this inspection that support the report findings. The System did not provide the majority of
the documents requested by the EPA inspection team prior to the conclusion of the inspection. During the
inspection, the System stated that documents were available to be reviewed.

System representatives provided the EPA inspection team with a Risk and Resiliency Assessment (RRA) and an
Emergency Response Plan (ERP), which were reviewed onsite, The RRA was certified on July 3, 2023 and the
ERP was certified July 31, 2023,
Sampling and Field Monitoring
The EPA inspection team collected both raw and treated water samples on June 3 through 7, 2024. Table 1
summarizes the samples taken during the inspection and the analyses performed. In summary, these samples
were analyzed for the 75 per- and polyfluoroalkyi substances (PFAS) analytes listed in Table 2, semivoiatile
organic compounds (SVOCs) listed in Table 4, volatile organic compounds (VOCs) listed in Table 6, total
petroleum hydrocarbons (TPHs) listed in Table 8,. metals {including mercury) listed in Table 10, and ethylene
dibromide (EDB). Prior to sample collection., the EPA inspection team determined if the raw water source or
entry point was producing water at the time of arrival. System representatives operated each source (e.g.,
pump-to-waste, pump-to-entry point) and entry point for a minimum of 10 minutes prior to the EPA
inspection team taking a sample. The System's authorized contractor removed sample tap fixtures (e.g.,
aerators), closed hot water plumbing valves to isolate treated sample taps, and otherwise prepared each raw
and treated sample site prior to sampling. The EPA inspection team flushed each raw and treated sample tap
for a minimum of five minutes prior to sample collection. The EPA inspection team measured free chlorine,
total chlorine, temperature, and pH of each sample at the time of the first sample collected at each sample
location. These field measurements are also compiled in Table 1 below. Photographs referenced in these
tables are included in the photograph log in Appendix A.
The System collected split samples immediately before or after for all the EPA samples unless otherwise
indicated below. The System's split sample results are included in the tables below for comparison. This report
does not cover data quality considerations for the System's split sample results.

PFAS Sampling
For the PFAS analysis, the laboratory used a modified version of EPA Method 537 with both liquid
chromatography tandem mass spectrometry (LC-MS-MS) and gas chromatography tandem mass spectrometry
(GC-MS-MS). Table 2 summarizes EPA's and HDOH's maximum contaminant levels (MCLs) for PFAS in drinking
water and HDOH's final action levels (Als) for PFAS in drinking water (rounded to two significant figures). Some
of EPA's MCLs are reported in units of Hazard Index (HI). The Hazard Index is displayed in Equation 1, with all
concentrations in parts per trillion (ppt), and connotated with brackets, ("[xxj").
„ Jf , ^ /[HFPO - DAp^ , f [PFBSppt] ^ , /[PFNAppt]^ , /[PFHxS^ „ ..

Table 3 contains a summary of EPA's results and the System's split sample results, including a summary of the
number of PFAS analytes detected, their detection range, and EPA MCLs that were exceeded for each sample.
Note the following quality considerations for EPA's sample results:
Method FTOH Samples
• According to the laboratory, samples were received with less than 2 days remaining on the holding
time or less than one shift (8 hours) remaining on a test with a holding time of 48 hours or less. As
such, the laboratory had insufficient time remaining to perform the analysis within holding time for the
following samples: 002, 003, 004D, 004 FB, 004, 006,. and Trip Blank. All samples were received by the
lab three days after collection. The samples were analyzed between two and eight days after their 14-
day holding time.
Method 537 IDA
• Reporting limits were raised for sample 004D due to limited sample volume.
• Target analyte HFPODA was detected in the method blank associated with the following samples: 002,
003, and Trip Blank. Therefore, the detection of HFPODA in these samples is not reliable.
The full EPA sample results are included in Table 15 and the laboratory reports in Attachment 1. Table 15 also
contains the PFAS analysis results for all environmental and quality control samples taken.
In summary:
• Exceedances: EPA's sample (004) its duplicate (0Q4D), and the System's split sample, taken at the Aiea
Halawa Shaft, exceeded the EPA and HI MCL for PFOA and PFOS. No additional exceedances in any
other samples were recorded.
• PFAS Detection: For the EPA samples, between one and 13 PFAS were detected in the samples - PFAS
concentrations were between 0.286 J and 10.9 ppt for all assets. For the System's split samples,
l
-------
Joint Base Pearl Harbor-Hickam
Inspection Dates: June 3-7, 2024
between 0 and 10 PFAS were detected in the samples - PFAS concentrations were between 0.402 J
and S.7 ppt for all assets.
• Duplicate 004 Samples: The same 13 PFAS were detected in the native (004) and duplicate sample
(004D). The results for the 13 PFAS were 0.82% to 13.8% different between the two samples, which
meets the acceptance criteria of 30% relative difference or less for duplicate samples.
• Field Blank and Trip Blank: There were no detections in the field blank (004FB), HFPODA was detected
in the trip blank: however, since this compound was detected in the laboratory method blank, this
detection is not reliable.

J = Result is less than the reporting limit but greater than or equal to the method
detection limit and the concentration is an approximate value,
a - This range is only of the detected PFAS, meaning it does not include non-detect
results. The analytes that the low-end and high-end concentrations represent are
provided in parenthesis. This excludes detections of HFPODA in samples 002, 003, and
Trip Blank due to laboratory method blank contamination.
b - The exceedances for PFOA and PFOS were for EPA MC I s, HI MCI s, and HI ALs, since
these limits are the same for all three.

Table 5 provides the results for the four SVOCs tested. The EPA laboratory reports can be found in Attachment
2. Note the following quality considerations for the EPA sample results:
Method EPA 8270E Samples
• According to the laboratory, sample 008 was received above temperature (no ice in cooler; 12.8'C).
These samples were rejected for analysis.
Method EPA 525.3 Samples
• According to the laboratory, samples 008 was received above temperature (no ice in cooler; 12.8°C).
These samples were rejected for analysis.
• 2-Methylnaphthalene was detected above the method detection limit (MDL) in the method blank
associated with samples 012 and 013. No material impact on reported result as samples were
ND for this parameter.
In summary:
• Exceedances: None of the samples exceeded the HDOH MCLs or ALs for SVOCs.
• Entry Point Samples: For EPA's results, SVOCs were detected at the inactive Aiea Halawa Shaft and Red
Hill Shaft (samples 004 and 006). Sample results were below HDOH ALs and had a "J" flag - the results
were less than the reporting limit but greater than or equal to the method detection limit and the
concentration is an approximate value. For the System's split sample results, there were no
detections.

• Samples 12 and 13 were prepped or analyzed past the recommended holding time for analytes TPH-d
andTPH-o,
• The calibration verification check for sample 013 did not meet the percent difference criteria for TPH-
o.
In summary:
• Exceedances: There were no MCLs or ALs for TPH at the time of this report.
• Detections: For EPA's results, TPH-d was detected in both Waiawa Shaft locations (002, and 003), one
Aiea Halawa Shaft location (004) and in two distribution system samples (005 and 010), For the TPH-d

the time of this report. The System's split sample results did not have detections for TPH-g, TPH-d,
TPH-o,
• Duplicates: For EPA's results, the duplicate sample for site 004 (004D) was non-detect for TPH-d while
sample 004 was 68 ug/L for TPH-d. The reporting limit for this analyte is 50 ug/L, therefore the percent
difference is not within quality criteria (within 30% difference).
To appropriately review and understand EPA's TPH sample results, there are important qualifiers for
consideration. Certain results have flags that provide additional context,
A3 = The sample was prepped/analyzed past the recommended holding time.
CI = The reported concentration for this analyte is below the quantitation limit.
C4 = The calibration verification check did not meet % difference criteria for this analyte,

The laboratory used EPA Method 200,8 and 245.1 for the metal analytes. Table 10 summarizes HDOH's MCLs
for four metal elements in drinking water. HI HDOH ALs are the same as the MCLs and, therefore, not
separately summarized in Table 10. Water was flushed before sample collection.

Table 11 provides the results for the samples tested for metals. The EPA laboratory reports can be found in
Attachment 3.
In summary:
• Exceedances: None of the samples exceeded the HDOH MCLs or ALs for any metals.
• Detections: For EPA's results, copper was detected in three source locations (002,. 003, and 004 and its
duplicate 004D) and in six distribution system locations (005, 008, 010, 011, 012, 013). Lead was
detected in one entry point location (004D) and one distribution system location (008), No beryllium
or mercury was detected in any of the samples. For the System's split samples, lead was detected in
two source locations (003 and 004) and in two distribution system locations (008 and 011).
• Duplicates: The same metal (copper) was detected in the native (004) and duplicate sample (004D).
The resuit for the copper was 21.2% different between the two samples, which meets the acceptance
criteria of 30% relative difference or less for duplicate samples. Lead was not detected in the native
sample (004) but was detected in the duplicate sample (004D). Since the detection limit is 0.13 ug/L
and the concentration in the duplicate sample was 0.19 ug/L, the relative difference is 37.5% and does
not meet the acceptance criteria of 30% relative difference or less for duplicate samples.

Dear Rear Admiral Bamett:
From June 3-7,2024, the United States Environmental Protection Agency, Region 9 (EPA) plans
to conduct an inspection of the Joint Base Pearl Harbor Hickam public water system (System) to
determine compliance with the requirements of the federal Safe Drinking Water Act (SDWA),
42 U.S.C. § 300f etseq. EPA inspections may include an evaluation of records, files, papers,
processes, controls, facilities and sources to determine whether public water systems or other
persons have acted or are acting in compliance with the SDWA.
The Hawaii Department of Health (HDOH) has primary enforcement responsibility under
Section 1413(a) of the SDWA, 42 U.S.C. § 300g-2(a), to ensure that suppliers of water in Hawaii
comply with the SDWA's requirements. However. EPA maintains federal oversight
responsibilities of the SDWA as well as direct enforcement authority to ensure water systems
are complying with national and EPA-approved state drinking water laws. This inspection will be
conducted under the authority vested in the Administrator of the EPA by Section 1445(b)(c) of
the SDWA, 42 U.S.C. §300 j-4 (b)(c), and duly delegated to the Drinking Water Section of the
Enforcement and Compliance Assurance Division.
EPA plans to conduct this inspection as part of EPA's comprehensive investigation of the Red
Hill Bulk Fuel Storage Facility to help ensure residents are receiving safe drinking water that is in
compliance with SDWA regulations and EPA's Administrative Consent Order signed on June 2,
2023.

Analytical test results meet all requirements of the associated regulatory program (e.g., NELAC (TNI), DoD, and ISO 17025)
unless otherwise noted under the individual analysis. Data qualifiers are applied to note exceptions. Noncompliant quality
control (QC) is further explained in narrative comments.
¦ QC results that exceed the upper limits and are associated with non-detect samples are qualified but further narration is not
required since the bias is high and does not change a non-detect result. Further narration is also not required with QC blank
detection when the associated sample concentration is non-detect or more than ten times the level in the blank.
¦ Matrix QC may not be reported if insufficient sample or site-specific QC samples were not submitted. In these situations, to
demonstrate precision and accuracy at a batch level, a LCS/LCSD is performed, unless otherwise specified in the method.
¦ Surrogate and/or isotope dilution analyte recoveries (if applicable) which are outside of the QC window are confirmed
unless attributed to a dilution or otherwise noted in the narrative.
Regulated compliance samples (e.g. SDWA, NPDES) must comply with the associated agency requirements/permits.
Measurement uncertainty values, as applicable, are available upon request.
Test results relate only to the sample tested. Clients should be aware that a critical step in a chemical or microbiological
analysis is the collection of the sample. Unless the sample analyzed is truly representative of the bulk of material involved,
the test results will be meaningless. If you have questions regarding the proper techniques of collecting samples, please
contact us. We cannot be held responsible for sample integrity, however, unless sampling has been performed by a member
of our staff. Times are local to the area of activity. Parameters listed in the 40 CFR Part 136 Table II as "analyze

Analytical test results meet all requirements of the associated regulatory program listed on the Accreditation/Certification Summary
Page unless otherwise noted under the individual analysis. Data qualifiers are applied to indicate exceptions. Noncompliant
quality control (QC) is further explained in narrative comments.
Matrix QC may not be reported if insufficient sample or site-specific QC samples were not submitted. In these situations, to
demonstrate precision and accuracy at a batch level, a LCS/LCSD may be performed, unless otherwise specified in the
method.
Surrogate and/or isotope dilution analyte recoveries (if applicable) which are outside of the QC window are confirmed
unless attributed to a dilution or otherwise noted in the narrative.
Regulated compliance samples (e.g. SDWA, NPDES) must comply with the associated agency requirements/permits.
Receipt
The samples were received on 6/8/2024 9:35 AM. Unless otherwise noted below, the samples arrived in good condition, and,
where required, properly preserved and on ice. The temperature of the cooler at receipt time was 2.2 C.
Receipt Exceptions
The Chain-of-Custody (COC) was incomplete as received. The COC is missing Sample State, Sample Preservation, Number of
containers per sample, amd Sample Type (Grab or Composite). This does not meet regulatory requirements. The client was
contacted and responded that the sample state of collection is Hawaii, the samples were unpreserved and 4 X 250 ml bottles were
submitted for each sample and that all were grab samples.
The container label for the following sample did not match the information listed on the Chain-of-Custody (COC): 004-D
(410-175226-5). The container labels list time of 09:50, while the COC lists time of 09:46. The client was contacted, and the lab
was instructed to login as listed on the COC.
GC/MS Semi VOA
Method FTOH: The initial calibration verification (ICV) result for batch 410-520647 was above the upper control limit. Sample
results were non-detects, and have been reported as qualified data.
004 FB (410-175226-6), 004 (410-175226-7), 006 (410-175226-8) and Trip Blank (410-175226-9)
Method FTOH: The initial calibration verification (ICV) result for batch 410-519643 was above the upper control limit. Sample
results were non-detects, and have been reported as qualified data.
Method FTOH: The following sample(s) was received with less than 2 days remaining on the holding time or less than one shift (8
hours) remaining on a test with a holding time of 48 hours or less. As such, the laboratory had insufficient time remaining to
perform the analysis within holding time: 001 P (410-175226-2), 002 (410-175226-3), 003 (410-175226-4), 004-D (410-175226-5),
004 FB (410-175226-6), 004 (410-175226-7), 006 (410-175226-8) and Trip Blank (410-175226-9).
Method FTOH: For the original extraction, the following sample was received with less than 2 days remaining on the holding time
or less than one shift (8 hours) remaining on a test with a holding time of 48 hours or less. As such, the laboratory had insufficient
time remaining to perform the analysis within holding time: 001 P (410-175226-2).
The re-extraction was also out of hold, but all surrogates are within specified windows.
The initial calibration verification (ICV) result for batch 410-521665 was above the upper control limit. Sample results were non-
detects, and have been reported as qualified data.
No additional analytical or quality issues were noted, other than those described above or in the Definitions/ Glossary page.
Method PFCJDA: The recovery for the internal standard peak areas is outside of QC acceptance limits in the laboratory control
spike duplicate sample (LCSD) associated with samples: 004-D (410-175226-5), 004 FB (410-175226-6) and 006 (410-175226-8).
Since the recovery for the labeled isotopes and targets are within QC acceptance limits in this LCSD, the data is reported.

Method PFCJDA: The recovery for target analyte 3:3 FTCA is outside of QC acceptance limits in the initial calibration verification
standard (ICV) associated with samples: 004-D (410-175226-5), 004 FB (410-175226-6) and 006 (410-175226-8). Since the
recovery is high and this target analyte is not detected, the data is reported
Method PFCJDA: Reporting limits were raised for the following sample: 004-D (410-175226-5) due to limited sample volume.
Method PFCJDA: The recovery for target analyte 3:3 FTCAis outside of QC acceptance limits in the initial calibration verification
standard (ICV) associated with sample: 004 (410-175226-7). Since the recovery is high and this target analyte is not detected, the
data is reported
Method PFCJDA: The recovery for the internal standard peak areas is outside of QC acceptance limits in the laboratory control
spike duplicate sample (LCSD) associated with samples: 004 (410-175226-7). Since the recovery for the labeled isotopes and
targets are within QC acceptance limits in this LCSD, the data is reported.
Method PFCJDA: The recovery for target analyte 3:3 FTCA in the initial calibration verification standard associated with the
following samples: 001 FBP (410-175226-1) and 001 P (410-175226-2) is outside of QC acceptance limits, biased high. Since the
recovery is high and the native analyte is not detected in the sample(s), the result(s) is reported.
Method PFCJDA: Isotope dilution analyte (IDA) recoveries were outside QC acceptance criteria in sample 001 FBP
(410-175226-1). The isotope dilution technique corrects the results for the target analytes for any losses that occur during the
sample extraction and/or concentration. For all IDA's, the signal to noise was greater than 10:1, therefore the data is reported.
Method PFCJDA: Target analyte(s) HFPODA were detected in the method blank associated with the following samples: 002
(410-175226-3), 003 (410-175226-4) and Trip Blank (410-175226-9). The following action was taken: This sample(s) was re-
extracted outside the required holding time and target analyte(s) were not detected in the re-extracted method blank.
No additional analytical or quality issues were noted, other than those described above or in the Definitions/ Glossary page.
