Extended Bioventing Testing Results at Site FSA-1 (Former Tank Nos. 19 and 20), Air Force Plant 4, Texas
Abstract
Parsons Engineering Science, Inc. (Parsons ES) is pleased to submit the results of the extended bioventing testing at Site FSA-1 at Air Force Plant 4 (AFP4), located in Fort Worth, Texas. Soil gas samples were collected, and in situ respiration testing was performed by Parsons ES from 7 through 10 April 1997 to assess the extent of remediation completed during approximately 1 year of full-scale air injection bioventing. The purpose of this letter is to summarize site and bioventing activities to date, present the results of the most recent respiration testing and soil gas sampling, and make recommendations based on site data. The as-built bioventing system and sampling/respiration testing locations are illustrated on Figure 1. Table 1 (attached) summarizes soil analytical results and compares detected concentrations to the Texas Natural Resource Conservation Commission (TNRCC) soil screening criteria. The attached Tables 2 and 3 provide results of initial and 1-year soil gas sampling and respiration testing, respectively.
