SUBSURFACE STRATIGRAPHY SURVEY
TYPE OF WORK
QRI defined the stratigraphy in the upper 100 feet of 56 acres in Hawthorne, California utilizing the Pulser™ Subsurface Survey System (Pulser™) in conjunction with existing databases. Previous lithologic studies presented chaotic bedding relationships that made it difficult to correlate from well to well. As a result, the Pulser™ technique was utilized to develop the stratigraphic framework for the site conceptual model. Additionally, the relationship between the existing lithologic and blow count databases was resolved due to the additional data provided by Pulser™. Pulser™ mapping non-intrusively delineated and refined four stratigraphic units across the project site that occurred from 0 to 100 feet below ground surface to facilitate the development of the sites conceptual model to aid in the remedial program.
