BACKGROUND

The AMR PWS is a community water system (PWS identification No. HIQ00Q337) located on a
U.S. military housing base adjacent to Joint Base Pearl Harbor-Hickam serving approximately
6,406 people with 1,090 service connections. The system serves the residents of the Aliamanu
and Red Hill housing areas located on AMR. USAG-HI-DPW owns and operates the AMR PWS.
The Hawaii Department of Health (HDOH) administers the Public Water System Supervision
Program in Hawaii and has been granted primary enforcement responsibility (i.e., primacy)
under the Safe Drinking Water Act.

The AMR PWS consecutive system receives wholesale treated drinking water from the Joint
Base Pearl Harbor-Hickam PWS (JBPHH PWS). The AMR PWS consists of a distribution system
with three AMR-owned ground storage tanks.

According to EPA's Enforcement and Compliance History Online (ECHO), the AMR PWS has not
experienced a regulatory violation since January 2019. Violation data prior to January 2019 is
not available in ECHO.

According to NAVFAV Hawaii staff, on May 6, 202.1, a valve opening operation was incorrectly
executed during a fuel mixing operation between tank IS and tank 20 in the Red Hiil bulk fuel
storage facility. A compression wave caused the end of the main fuel line to violently displace,
which caused the lateral line for tank 20 to shear off. spilling an unknown amount of jet
propellant-5 (JP-5) fuel. The spilled JP-5 fuel reached a sump pump for collecting aqueous
firefighting foam (AFFF) and was pumped into the 14-inch overhead AFFF polyvinyl chloride
(PVC) recovery pipe system.

According to the NAVFAC Hawaii "initial Release Response Report," on November 20, 2021, a
worker operating a trolley in the lower access tunnel ("Adit 3") of the Red Hill bulk fuel storage
facility cracked a clean-out valve for the overhead AFFF recovery pipe approximately 400 feet
east of the Adit 3 Red Hiil pumping station, spilling an estimated 9,000 gallons of JP-5 fuel and
water mixture. The JP-5 fuel mixture poured onto the concrete tunnel floor to the trolley tracks
and traveled approximately 750 feet over the underlying water development tunnel to a low
spot in the tunnel. The JP-5 fuel mixture accumulated in a groundwater sump that prevents
flooding in the access tunnel. The JP-5 fuel mixture was then transferred via a sump pump to
the groundwater sump drain holding tank and a connected sump drain leach tank located
outside the Adit 3 tunnel. At some point, the JP-5 fuel mixture in the Adit 3 tunnel entered a
nearby Hume drain, leaching the JP-5 fuel mixture into the underlying basalt bedrock, and
entered the Red Hill water development tunnel.

On November 21,2021, the Navy public affairs office issued a media release to the public and
AMR regarding the JP-5 fuel spill, stating that "personnel responded to what was initially

assessed as a water leak shortly after 1700 (5:00 pm) on November 20, 202:1. This pipe is not
connected to the Red Hill Fuel tanks or main fue! pipelines, all of which arc secure. Overnight,
the release began to contain some amount of fuel which increased into Sunday (November 21,
2021) morning. Approximately 14,000 gallons of a mix of water and fuel was contained in the
lower tunnel (Adit 3) and has been recovered and transferred to an above-ground storage tank
as of midday Sunday. The Navy made initial notification to the Department of Health Saturday
night (November 20, 2021) and is providing updates Sunday. There are no signs or indication of
any releases to the environment and the drinking water remains safe to drink,"

According to the NAVFAC Hawaii "Initial Release Response Report," on December 2, 2021,
tubing connected to a photoionization detector (PID) was lowered into the Red Hill shaft,
resulting in a maximum reading of 110 parts per million by volume (ppmv) of volatile organic
compounds (VOCs). A bailer sample was also collected from the Red Hill shaft and a sheen with
fuel bubbles floating on the surface was noticed, indicating fuel had reached the water
development tunnel. The Navy public affairs office issued a media release to the public and
AMR that petroleum products had been detected in the Red Hill well and the level of the
petroleum hydrocarbons in the well were roughly 4 to 10 times below the HDOH action level.

On December 2,2021, the Army authorized evacuation of personnel, dependents, and
employees impacted by the water contamination in the AMR and Red Hill housing areas.

On December 1.1, 2021, AMR PWS staff stated that USA6-HI met with the U.S. Army Corps of
Engineers (US-ACOE} to discuss additional water treatment options.

In late December of 2021, AMR PWS staff stated that USAG-HI and US-ACOE decide to move
forward with installation of granulated activated carbon (GAC) filters on the entry points to the
AMR PWS distribution system from the JBPHH PWS.

On February 28, 2022, HDOH approved the installation of the GAC filter system on the entry
point from JBPHH PWS's S-l and S-2 tanks.

On March 16, 2022, the GAC fitters were in placed into operation.

On March 28, 2022, HDOH approved the installation of the GAC filter system on the entry point
from JBPHH PWS's Red Hill tanks.

FACILITY OPERATIONS SUMMARY

The AMR PWS is a consecutive system that receives wholesale treated drinking water from the
JBPHH PWS. Under normal conditions, water for the Aliamanu and Red Hill housing areas is
chlorinated and fluorinated at three JBPHH PWS sources (Waiawa shaft, Halawa shaft, and Red

Hill shaft) and then stored in two JBPHH PWS 6-million-gallon ground storage tanks (S-l and 5-
2) and two JBPHH PWS 250,000-gailon Red Hill ground storage tanks. Treated water then
passes through a master meter on the outlet pipe from the tanks and enters the AMR
distribution system.

Currently, treated water from the JBPHH PWS's S-l and S-2 tanks enters the AMR PWS point of
entry and undergoes additional treatment through two-stage GAC filtration, with two
treatment units operating in paraliei. Once the water passes through the filters, it is disinfected
with sodium hypochlorite before it is split between two storage tanks. The GAC filters on the
entry point from the JBPHH PWS Red Hill tanks were not in service at the time of the inspection.
AMR PWS is currently testing the filters, as the JBPHH PWS has concerns about water pressure
in the event water is needed for the AFFF system at the Red Hill bulk fuel storage site.

FIELD ACTIVITIES SUMMARY

NEIC conducted the on-site inspection on April 7, 2022. The NEIC inspection team consisted of
Hannah Branning and David Parker. Maria Alberty and Emma Young from EPA Region 9 also
participated in the inspection. Whit Somerall from HDOH was also present during the
inspection. Photographs taken by NEIC during the inspection are found in Appendix A. NEIC
conducted an inspection of the JBPHH PWS from April 4-8, 2022 (report NEICVP1463E01).

On April 7, 2022, NEIC inspectors conducted an opening meeting and presented credentials to

USAG-HI-DPW director. On April 7, 2022, NEIC inspectors conducted a closing
meeting with USAG-HI-DPW and HDOH representatives. Lists of the meeting attendees are
found in Appendix B.

NEIC assessed the AMR PWS's compliance with the SDWA. The assessment included detailed
discussions about and field observations of the distribution system, finished water storage,
pumps, pumping facilities and controls, monitoring, reporting, data verification, system
management and operation, and operator compliance with state requirements. The
assessment also included a review of records, including system maps and schematic diagrams,
monitoring records, customer complaint logs, public notifications, engineering evaluations, and
standard operating procedures.
