Investigations of Study Area 43L Historic Gas Station Site at Fort Devens, Massachusetts have resulted in the decision that no further hazardous waste studies or remediation are required at this site. Study Area 43L was identified in the Federal Facilities Agreement between the U.S. Environmental Protection Agency and the U.S. Department of Defense as a potential site of contamination. Fort Devens was placed on the National Priorities List under the Comprehensive Environmental Response, Compensation and Liability Act as amended by the Superfund Amendments and Reauthorization Act on December 21, 1989. In addition, under Public Law 101-510, the Defense Base Realignment and Closure Act of 1990, Fort Devens was selected for cessation of operations and closure. In accordance with these acts, numerous studies, including a Master Environmental Plan, an Enhanced Preliminary Assessment, and an underground storage tank removal program, have been conducted which address Study Area 43L. An investigation of subsurface soil at Study Area 43L was conducted by Kurz Associates in 1989 as part of an underground storage tank removal program at Fort Devens. The three underground storage tanks were removed, and were observed to be in good condition. The headspace of nine soil samples from each excavation were screened for total volatile organic compounds with a photoionization detector. Concentrations ranged from 0.4 to 6.8 parts per million. Four composite soil samples were collected from the excavations for total petroleum hydrocarbon analysis. The concentrations ranged from 57 to 108 parts per million. After assessing the distribution and migration potential of the contaminants at the station, it was concluded by Fort Devens personnel that groundwater was not being impacted and that current site conditions, at the time, posed no significant risk to potential receptors. Based on this assessment, the excavations were backfilled, and no additional investigation was conducted.
