Geophysical surveys integrated in preremedial site investigations for a landfill in New Mexico

Abstract

Surface geophysical surveys were integrated in a preremedial site investigative program at a landfill in New Mexico belonging to the Bureau of Land Management. The purpose of this program was not only to conduct the investigation but also to establish a sound technical framework for future site investigations in that geologic _,nd hydrogeologic setting. The emphasis was on identifying initial characterization procedures that would decrease the need for sampling and drilling on a random grid. A prior preliminary assessment and site investigation indicated the presence of some hazardous waste compounds but yielded contradictory information about the locations of trenches and pits.
