Former Warehouse Area, Site Investigation Report; Volume 2 (Appendices): Buckley Air National Guard Base, Aurura, Colorado.

This Site Investigation (SI) Report presents the results of the Former Warehouse Area (FWA) Site Investigation at the Buckley Air National Guard Base (Buckley ANGB or Base) located in Aurora, Colorado. Work was conducted under the Installation Restoration Program (IRP). The purpose of the SI was to confirm the presence and determine the nature of soil and groundwater COPC at the FWA. The FWA SI was accomplished by conducting a sequential environmental field investigation involving a geophysical survey, followed by a drilling and sampling program that included collecting and analyzing soil gas, soil, and groundwater samples within the FWA. This FWA SI report defines the nature of COPC present at the FWA, identifies potential source areas for COPC, and characterizes site geology and hydrogeology. All site investigation activities were conducted in accordance with the Final Former Warehouse Area Site Investigation Work Plan, dated October 4, 1996, prepared by Stone & Webster for the Departments of the Army and the Air Force National Guard Bureau. The methods and procedures presented in the Work Plan followed U.S. EPA guidance documents and Air National Guard (ANG) requirements. Detailed background information based on previous investigations conducted at the Buckley ANGB are not presented in this report. Instead, summary information is presented and documents containing the detailed site information are referenced. ; ADA338713
