This paper describes an approach that can be applied to a hazardous waste site where known groundwater contamination exists are remedial action is necessary to mitigate the environmental concerns. The sampling program is conducted to locate, as accurately as possible, the position, extent and depth of contaminant source areas, and to identify the potential contaminants present as well as the potential extent of contaminant migration in the soil and groundwater. These sampling procedures utilize the maximum number of backhoe trench excavations to locate the apparent boundary of contaminant source areas and obtain composite soil samples along a prescribed coordinate grid system and field-implemented analytical techniques to screen soil samples and eliminate those of little or no contamination. Laboratory analytical procedures are used to characterize the waste constituents found in the source areas and contaminated soils, and to provide the necessary level of quality assurance. In all, the sampling program described herein maximizes the use of field-implemented analytical techniques which reduces the overall cost of laboratory analytical procedures.
