## Summary

Sites 11 and 12 are adjacent to each other with similar groundwater contamination and hydrogeologic characteristics; thus, the sites were combined into one ROD.   Site 11 consists of a former boiler house, a former diked fuel storage area, and a former deep bedrock well, known as ?F Well?. This ROD addresses groundwater contamination associated with the former F-Well, a non-operational well that was not properly abandoned until the remedial investigation from 1998-2001.  Previous actions have addressed contamination associated with the former diked fuel storage area.  Site 12 consists of Building 167, which was primarily used for the preparation of rocket casings. The two main sources of contamination at Site 12 are the former unlined wastewater sump (SWMU 37N) and the plating tank (SWMU 52.) Past removal actions at Site 12 include the removal of the former sump and excavation and disposal of contaminated soils. The primary COCs at both sites consist of VOCs and metals.  The ROD selects 1) Enhanced Anaerobic Biodegradation focusing on the areas of high concentrations of VOCs; 2) Monitored Natural Attenuation; 3) Long-term groundwater monitoring; and 4) Institutional controls to prevent the potable use of groundwater at Sites 11 and 12 and to restrict construction activities at Site 11.
