If groundwater is found on site, what method cannot be used for closure?

When groundwater is encountered on a site, the method of closure that is not applicable is the Generic Remedy Cleanup. This is due to the fact that the Generic Remedy Cleanup typically refers to more generalized, non-specific approaches that may not adequately address the complexities involved in the presence of groundwater contamination.

Groundwater contamination demands a tailored assessment and remediation strategy that specifically considers hydrogeological conditions and the potential risks to human health and the environment. Therefore, generic methods that do not engage with the specific dynamics of groundwater pollution would not be suitable for closure processes.

In contrast, the other options are more adaptable and can be utilized in contexts where groundwater is present. Documentation audits and site assessment reports can provide detailed information about the specific site conditions, including groundwater levels and contamination. These reports can inform stakeholders and regulatory bodies about the situation and any necessary remediation actions. Additionally, soil removal techniques can be employed to remediate soil contamination, though with groundwater present, careful consideration and additional methods may also be necessary to ensure that groundwater contamination does not persist.
