Abstract
The purpose of the radiological survey was to identify areas of elevated gamma radiation in Operable Unit 1 as compared to normal background levels. The purpose of the infrared survey was to identify any heat signatures associated with the ongoing subsurface smoldering event in one of the non-radiological cells in Operable Unit 2, and to help delineate the extent of this event. EPA chose to use the ASPECT airplane for this survey due to access issues on the site that prevented ground-based scanning, specifically the heavy vegetation on parts of the landfill. The responsible parties at the site conducted a ground-based radiation survey as part of the Operable Unit 1 Remedial Investigation and EPA chose to refresh the radiation survey and reconfirm its results. The ASPECT radiological survey confirmed the previous data showing surface gamma emissions above background levels in a portion of Area 2 of Operable Unit 1, but this area above background levels is within the fenced area of the site and is inaccessible to the public, so it does not pose a public health risk. The results are consistent with previous studies indicating that the radiological wastes remain in the previously identified areas of Operable Unit 1, Areas 1 and 2.
