Is there a remediation standard the Navy must comply with?
Under Hawaiʻi Administrative Rules, Section 11-280.1-65.3 (pdf), the Navy must remediate to the standards in Table 1 or propose a different standard for Hawai'i Department of Health's (DOH) approval. To date, the Navy has not proposed, and the DOH has not approved, a different remediation standard.

Federal Agencies and Organizations Addressing Environmental Asthma
EPA works with federal agencies, national nonprofit organizations and EPA regional offices to encourage integration of outreach and education on environmental asthma triggers.

Is the Navy required to investigate and remediate all confirmed releases from the Red Hill Facility, even those before the 2021 JP-5 releases?
Yes, as part of the closure process, the Navy is required to investigate and remediate all historical releases, including those that occurred prior to November 2021. The Navy is conducting site assessments and investigations to determine the location, nature, and extent of contamination, as well as develop a conceptual site…

EPA Announces $10.5 Million for Tennessee to Address PFAS in Drinking Water
U.S. Environmental Protection Agency (EPA) has announced $10,528,000 in new Emerging Contaminants in Small or Disadvantaged Communities (EC-SDC) grant funding to address PFAS and emerging contaminants in Tennessee communities that need it most.
-
Why does it take so long before laboratory reports are finalized?
The regulatory agencies require the Navy to follow a rigorous, step by step quality assurance process, increasing the time to produce the final report. Following the 2021 releases at Red Hill, regulators required much more frequent sampling, which created a surge in samples and led to a backlog in sample…
-
Why would regulators allow a drinking water well to operate or reopen within a mile of the Red Hill Release?
From a scientific standpoint, the migration of petroleum contamination in groundwater has been studied extensively across the nation. It is well documented that petroleum plumes do not typically travel far from where they enter the environment. At Red Hill, routine samples are collected from approximately 47 wells to monitor the…
-
Navy labs modified reports after they were issued – is this normal?
Validating data can result in revisions. This is normal and an indication the lab is performing the appropriate data quality checks. The data validation process can take a long time. Regulators have access to and review both the validated and unvalidated data.
-
Did delays in reporting results between May and November 2021 prevent regulators from conducting in-depth analysis of water contaminants and impacts to Red Hill Shaft?
No. During this time period, preliminary data spreadsheets were submitted to the Hawai’i Department of Health (DOH) within two to three months after sample collection. The results were posted on DOH’s website and presented to the public by DOH at the October 28, 2021 Fuel Tank Advisory Committee (FTAC) meeting…
-
Will remedial options besides natural attenuation be considered?
Yes. The Navy will be required to submit a remediation plan. As with any site, the regulators will require multiple remedial alternatives to be considered and evaluated by the Navy. However, additional data about impacts to the vadose zone are needed before plans can be developed and before regulators can…

EPA Announces $9.8 Million for South Carolina to Address PFAS in Drinking Water
U.S. Environmental Protection Agency (EPA) has announced $9,829,000 million in new Emerging Contaminants in Small or Disadvantaged Communities (EC-SDC) grant funding to address PFAS and emerging contaminants in South Carolina communities that need it most.
-
Is the Navy currently considering any active remediation technologies?
The Navy continues to investigate the nature and extent of contamination and will propose remedial options based on the results. While natural attenuation will continue to be an important mechanism for reducing fuel levels in the aquifer, targeted active remediation of contaminants in the vadose zone and potentially the shallow…
