Remediation activities are currently underway in accordance with the Record of Decision, which was signed in August 2013. The cleanup plan involves excavating impacted soil and transporting offsite to a permitted disposal facility, specifically designed for the safe disposal of radiological materials. In addition, USACE plans to monitor the natural physical and chemical processes in groundwater, after the soil has been removed, as they are expected to reduce remaining contaminant concentrations.
USACE is currently conducting a five-year review. The purpose of the review is to evaluate the implementation and performance of the site remedy to determine if the remedy is and will continue to protect human health and the environment. The remedial action includes soil excavation and monitored natural attenuation for groundwater to address radioactive contamination as defined in the Record of Decision published by USACE in August 2013.
