Lexington-Bluegrass Army Depot Groundwater Investigation Report, Phase I - Final. Volume IV. Lexington-Bluegrass Army Depot, Lexington, Kentucky


Book Description

This appendix provides the sampling results which serve as the basis for the baseline risk assessment evaluation of each of the two groundwater areas at the LBAD. The tables also provide the frequency of detection, average concentration detected, the range of concentrations detected, the 95 percent UCL, and the exposure concentration associated with each of the chemicals detected in the two areas. In addition, results from the two groundwater background samples are also included.




Lexington-Bluegrass Army Depot Groundwater Investigation Report, Phase I - Final. Volume II. Lexington-Bluegrass Army Depot, Lexington, Kentucky


Book Description

This baseline risk assessment section provides an evaluation of the potential risks to human health from exposure to chemicals detected in groundwater in areas of concern at the LBAD. By definition, a baseline risk assessment (risk assessment) is an analysis of the potential adverse health effects (current or future) caused by hazardous substance releases from the site in the absence of any actions to control or mitigate these releases.




Lexington-Bluegrass Army Depot Groundwater Investigation Report, Phase I - Final. Volume I. Lexington-Bluegrass Army Depot, Lexington, Kentucky


Book Description

The report presents the information and findings for ground-water and those media expected to affect groundwater (soil, sediment, surface water). A baseline risk assessment was performed to evaluate the possibility of human health and ecological effects in receptors potentially subject to exposure to chemicals contamination detected in the groundwater at LBAD. Based on groundwater flow and base activities, the site was divided into northern and southern sections for risk assessment purposes. Based on a conservative risk evaluation, both the groundwater in the northern and the southern sections of LBAD possess potentially unacceptable levels of human health or ecological risk.










Site Specific Environmental Baseline Survey for Select Building and Parking Area, Lexington-Bluegrass Army Depot, Lexington, Kentucky


Book Description

The Department of Defense (DoD) has established policy guidelines for an environmental review process to transfer, outgrant, or dispose of property by reaching a Finding of Suitability to Transfer (FOST). To support the FOST, an Environmental Baseline Survey (EBS) must be prepared for each deed transfer. An EBS for the Lexington Facility was conducted in the form of a Community Environmental Response Facilitation Act (CERFA) investigation which was finalized in April 1994. The CERFA investigation included a review of existing investigative documents; U.S. Environmental Protection Agency (USEPA), State, and county regulatory records; environmental data bases; and title documents pertaining to the Depot. In addition, the Army conducted interviews and visual inspections of the Depot as well as visual inspections and data base searches for the surrounding properties. This site specific Environmental Baseline Survey has been prepared to determine the environmental suitability of twenty two buildings and a parking lot at Lexington-Bluegrass Army Depot (LBAD), Lexington, Kentucky for property transfer. Specifically the transfer includes buildings 1, 3, 5, 6, 14, 15, 16, 17, 18, 22, 23, 101, 109, 113, 118, 150, 151, 152, 153, 220, 221, 228 and Parking Lot "C". This site specific EBS included interviews, a records review, and a visual site inspection (VSI) of the twenty two buildings. No sampling was conducted as part of this survey. The purpose of the Site Specific EBS is to update the environmental condition of the proposed transfer parcels specifically identifying any environmental changes which may have occurred since the preparation of the CERFA report. As part of the visual walkthrough of the buildings, areas containing chipped or loose paint and damaged floor tiles or asbestos containing materials were noted.
