Installation Restoration Program. Phase II. Problem Confirmation and Quantification, Myrtle Beach Air Force Base, South Carolina. Volume 1. Revised.
Abstract:
Pursuant to the Installation Restoration Program IRP Phase II Objectives, drilling, soil-sampling, and ground-water monitoring programs were conducted at seven of the potential contaminant source areas that have been identified within the boundaries of Myrtle Beach Air Force Base MBAFB these areas include Fire Training Areas 1 and 2, LandfillsWeathering Pit 2, Fire Training Area 3, Weathering Pit 1, POL Fuel Spill Area, Flight Line Area, and Landfills 1 and 4. An additional site, the Pipeline Spill Area, was also evaluated using existing subsurface data, hand-augerOVA results, and findings from a surface geophysical survey that was conducted to delineate plumes of high-conductivity substances. All available data were then evaluated to define important site hydrogeologic conditions including the textural composition of shallow sedimentray deposits, hydraulic head relationships between upper and lower water-bearing zones, groundwater flow patterns within the watertable aquifier, groundwater quality trends, contaminantsource area relationships, and factors controlling groundwater flow andor contaminant migration.
