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 make informed decisions about remediation. Regulators will rely on site-specific data collected from site assessment and site investigation to evaluate any proposed remedial options based on the best available science and technology. We will consider the limitations of all remedial options and seek a suite of different techniques to optimize clean-up.
