Abstract

This interim action is protective of human health and the environment in the short term and is intended to provide adequate protection until a final ROD is signed; the action complies with federal and Commonwealth of Massachusetts requirements that are applicable or relevant and appropriate for this limited-scope action, and is cost-effective. This action is an interim solution only, and is not intended to utilize permanent solutions and alternative treatment technologies to the maximum extent practicable for this OU. The groundwater will not be treated under the selected remedy. However, the source of groundwater contamination (the CS-19 soil OU) is currently being removed under a separate removal action (AFCEE 2003). Two feet of soil and the encompassed military munitions (MM) and/or munitions constituents (MC) debris have already been excavated from the site, and the soil has been treated in a low temperature thermal desorption unit to destroy hexahydro-l, 3,5-trinitro-l, 3,5-triazine (RDX); additional removal of soil and MM and/or MC debris at the site is ongoing. There is a statutory preference for treatment as a principal element of the remedies (i.e., reduce the toxicity, mobility, or volume of contaminants comprising principal threats through treatment). Because this interim action does not constitute the final remedy for the OU, the statutory preference for remedies that employ treatment that reduces toxicity, mobility, or volume as a principle element will be addressed by the final response action. Subsequent actions are planned to address fully the threats posed by conditions at this OU, and review of the site and the remedy will be ongoing as AFCEE and the Army continue to develop a final remedy for groundwater at CS-19. Because RDX will remain in the aquifer for several years above levels that allow for unlimited use and unrestricted exposure, five-year reviews will be conducted to ensure that the interim action continues to be protective of human health and the environment.
