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.

-
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…
-
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…

Why is the ʻAiea-Hālawa GAC-IX filter being proposed for removal after 9 quarters? What standards will be used to determine acceptable PFAS levels?
The granular activated carbon-ion exchange (GAC-IX) filter operational duration is flexible and not tied to a specific number of performance periods. Instead, the operational duration is dictated by site-specific conditions, regulatory requirements, and data objectives. The Navy proposal is to remove the filter after nine quarters. However, the filter will…
