i 1krCrNSOR.. SACRAMENTO ' PROJECT SUMMARY ' During the period of June. 28 through July 3 , 1991, Versar, Inc. (Versar) conducted an interim remediation/pilot study at the Pacific Bell facility located on Ashley Lane, Stockton, ' California. The interim remediation/pilot study included the installation of four soil-vapor extraction wells and a soil--vapor extraction and abatement system, the collection and analysis of soil and soil-vapor samples, the collection and collation of soil-vapor data and the preparation of this report. Mr. Stephen Wilson, Senior Geologist, and Ms. Yvonne Lembi, Geologist, supervised the drilling of the soil-vapor extraction wells, Mr. ' Stephen Wilson and Mr. James Jensen, Geologist, supervised the installation and operation of the soil-vapor extraction system. Mr. Wilson prepared this report. The interim remediation/pilot I study was performed under the supervision of Mr. James Frantes, Division Director, a registered geologist in the State of California. The following brief conclusions summarize the findings of Versar's interim remediation/pilot study: • Versar operated a soil--vapor extraction pilot study at the Pacific Bell Ashley Lane facility for a total of 93 days. The SVE system was operational for 66 days and during that time removed an estimated 0. 5 gallons of rdiesel from the impacted soils at the site. • Based on the operational data from the study, Versar concludes that the subsurface at the site is ' suitable for soil-vapor extraction implementation. However, based on the very low volume of diesel fuel recovered, the soils at the site cannot be satisfactorily remediated by soil-vapor extraction.
