Results of Soil Vapor Sampling at SA 6, McClellan Air Force Base, California
Abstract
This letter presents the results of the soil vapor sampling performed by Parsons Engineering Science, Inc. (Parsons ES) on 11 March 1998 and 22 May 1998 at Study Area 6 (SA 6), McClellan Air Force Base (AFB), California. Soil vapor samples were collected by Parsons ES to assess the effectiveness of more than 4 years of bioventing in remediating the volatile organic compound (VOC) and total petroleum hydrocarbon (TPH) contamination in site soil. The soil vapor sampling event was performed in accordance with the Final Sampling and Analysis Plan to Support Recommendation for No Further Investigation at SA 6 (Parsons ES, 1998) which has been reviewed and approved by the Air Force Center for Environmental Excellence (AFCEE), McClellan AFB, and the California Regional Water Quality Control Board, Central Valley Division. The SAP provides a detailed site description and history for SA 6 as well as soil and soil vapor sampling procedures and criteria to be used to support a no further investigation (NFI) recommendation. The purpose of this letter is to summarize the soil vapor sampling results and provide recommendations for confirmation soil sampling based on these results. A site layout illustrating soil vapor sampling locations and proposed soil sampling locations (Figure 1) and a table summarizing soil vapor results (Table 1) are attached.
