The U.S. Environmental Protection Agency issued a final report in March 2026 concluding that no residual fuel or fuel-related contaminants remain in the Joint Base Pearl Harbor-Hickam (JBPHH) or Aliamanu Military Reservation (AMR) public water systems following the November 2021 fuel release from the Navy’s Red Hill Bulk Fuel Storage Facility. All drinking water in the affected systems now meets federal drinking water standards. The report effectively closes the federal regulatory chapter on the most consequential military fuel contamination of an American drinking water source in recent history — but Hawaii’s state-level response, including new legislation and a proposed treatment facility, is still actively unfolding.
What Happened in 2021
Red Hill is a Navy fuel storage complex above Oahu’s primary drinking water aquifer. On November 20, 2021, an estimated 14,000 gallons of jet fuel were released into the soil above the aquifer, eventually reaching the Red Hill Shaft — a Navy drinking water intake serving JBPHH and surrounding areas. Approximately 93,000 residents of Navy housing, AMR, and connected systems were exposed to fuel-contaminated tap water. Reported symptoms included nausea, headaches, rashes, and respiratory irritation; thousands of families were temporarily relocated.
The contamination prompted:
- An immediate shutdown of the Red Hill Shaft as a drinking water source
- A state Department of Health emergency order in December 2021
- A federal Administrative Order on Consent between the Navy, EPA, and Hawaii DOH in May 2022 mandating defueling and eventual closure of the Red Hill facility
- The Navy’s commitment to permanently close Red Hill by 2027
- Years of remediation, monitoring, and community oversight
What the March 2026 EPA Report Says
The final EPA report covers public water system testing data from 2022 through early 2026. Key conclusions:
| Finding | Status |
|---|---|
| Residual fuel in JBPHH water system | None detected |
| Residual fuel in AMR water system | None detected |
| Compliance with federal drinking water standards | Yes, all standards met |
| Aquifer contamination remediation | Ongoing — separate from public water system |
The distinction between public water system status (clean) and aquifer status (still being remediated) is important. The water system that delivers tap water to JBPHH residents is now fed from sources that test clean, but the underlying groundwater contaminated in 2021 is still being addressed through a separate, longer-running cleanup effort.
Why “All Clear” Isn’t the End of the Story
EPA’s report addresses federal Safe Drinking Water Act compliance. It does not address:
- Long-term health effects in residents exposed during 2021–2022. Multiple ongoing health studies, including one through the University of Hawaii, are tracking former Red Hill water users.
- Aquifer-level remediation, which is governed by the May 2022 federal AOC and continues under Navy management with EPA and Hawaii DOH oversight.
- Closure of the Red Hill facility itself, which is on track for completion before 2028 but has experienced multiple delays.
- Trust restoration with Hawaii’s military and civilian communities, who have spent four years pressing for transparency and independent verification.
Hawaii’s State-Level Response Continues
While the federal regulatory closure is significant, the Hawaii state legislature has been actively working on independent oversight. HB1926 HD1, which passed Senate committees on March 16, 2026, would provide funding for:
- Red Hill remediation research
- Environmental monitoring independent of Navy data
- Groundwater modeling to predict contaminant transport
- Public education on water quality in affected areas
- Independent water testing and expert review of Navy water data
The bill is sponsored by legislators from districts surrounding Pearl Harbor and reflects skepticism that federal-level “all clear” findings are sufficient. The historical pattern in military environmental contamination — Camp Lejeune most prominently — has been that affected residents’ concerns ultimately proved warranted long after federal agencies declared the immediate danger past. Hawaii legislators appear determined to maintain independent verification capacity for years to come. (For comparison, see our coverage of the Camp Lejeune 2026 update.)
The Proposed Red Hill Shaft Water Treatment Facility
Separately, the Navy has proposed building a new water treatment facility at the Red Hill Shaft to treat water from that intake and bring it back into use as a drinking water source. A draft Environmental Assessment for the facility was published in late 2025; the facility would treat extracted water to meet:
- All National Primary Drinking Water Regulations
- All Hawaii Department of Health Safe Drinking Water Standards
- Specific commitments under the January 2022 Red Hill Shaft Recovery and Monitoring Plan
If approved and built, the treatment facility would represent a structural shift: rather than abandon the Red Hill Shaft as a drinking water source, the Navy would treat the water continuously to address residual aquifer contamination. The trade-off is that the operating treatment plant becomes the system’s sole defense against any future contamination event — a single barrier rather than the multi-barrier preference EPA generally recommends.
Updated Community Engagement Plan
Under the 2026 Community Engagement Plan, also adopted earlier this year, the Navy:
- Is no longer required to attend Community Representation Initiative (CRI) meetings (the citizen oversight body created post-contamination)
- Remains committed to attending Fuel Tank Advisory Committee meetings and impacted Neighborhood Board meetings
- Will host an annual Town Hall, plus open houses, drinking water information booths, and webinars
The reduction in CRI participation has been controversial. The CRI was established specifically as a vehicle for community oversight of remediation; the Navy stepping back from required attendance — even while continuing other community engagement — has been read by some Hawaii residents as a signaling shift toward case-closed treatment of the issue.
What Red Hill Means for Other Drinking Water Sources
Red Hill is the most prominent recent example of a military fuel contamination event affecting public drinking water, but it is not isolated. The Department of Defense has identified hundreds of military installations with confirmed groundwater contamination from PFAS-containing aqueous film-forming foam (AFFF), petroleum products, and other industrial chemicals. The Red Hill response framework — federal AOC, state oversight, multi-year remediation, independent monitoring — is now a template that could apply at dozens of other affected installations.

What You Can Do
-
For Hawaii residents living in or near JBPHH: EPA’s report concludes the public water system is clean, but if you have ongoing health concerns or want independent verification, the Hawaii Department of Health publishes monitoring data at health.hawaii.gov. HB1926 HD1, if enacted, would expand independent testing capacity.
-
For residents anywhere downstream of a military installation: Ask your utility whether your source water is monitored for fuel-related compounds (BTEX — benzene, toluene, ethylbenzene, xylenes) and PFAS. Both are common at military sites.
-
For households wanting redundant protection: Standard activated carbon filtration removes BTEX and most VOCs effectively. See our best under-sink water filters, best pitcher filters, and best whole-house water filters for certified options. PFAS removal requires specifically NSF/ANSI 53 + P473 certified filters.
-
For policy engagement: The Hawaii model — state legislative funding for independent monitoring of federal sites — is replicable. State legislators in any state hosting a contaminated military installation have legal authority to fund independent oversight.
How WaterVerge Tracks This
WaterVerge integrates SDWIS compliance data into city pages, including for utilities serving Joint Base Pearl Harbor-Hickam areas. As the Red Hill Shaft Water Treatment Facility’s environmental review proceeds and as Hawaii state monitoring data becomes available, WaterVerge will reflect compliance status changes. Search your city to see current drinking water data for the system serving your address.
