Final Sampling and Analysis Plan for Background Sampling, Fort Sheridan, Illinois
Abstract
The existing background database for Fort Sheridan is insufficient to permit a determination of background concentrations at acceptable statistical confidence levels. This Background Sampling and Analysis Plan (BSAP) is designed to address this issue through the collection of additional background samples at Fort Sheridan to support the statistical analysis and the Baseline Risk Assessment (BRA). Some background data have been collected during previous phases of work at Fort Sheridan and are to be validated according to procedures listed in the Overall Quality Assurance Project Plan (OQAPP) (ESE, 1995). It is anticipated that the data collected under this BSAP will be combined with the validated portion of the previously collected data to constitute the complete background database at Fort Sheridan. The scope of work defined under this BSAP will provide adequate data to permit the objectives of the background sampling to be achieved even if none of the previously collected data pass the independent data validation program. Background Sampling Areas Areas for the collection of background samples were selected by the Base Realignment and Closure (BRAC) Cleanup Team (BCT) during a site visit on July 19, 1994. These areas were selected because they are believed to be unaffected by activities at Fort Sheridan based on a review of available site records and aerial photographs. Ten locations for the collection of background samples have been identified. These locations have been grouped into five areas, based primarily on physical proximity, as follows: Background Area - North; Background Area - East * Background Area - South; Background Area - West; Lake Michigan Bluff Area; Background Surface Water and Sediment Sampling Locations.
