AUTOMATING SHALLOW SEISMIC IMAGING
Our current EMSP project continues an effort begun in 1997 to develop ultrashallow seismic imaging as a cost-effective method applicable to DOE facilities. The objective of the present research is to refine and demonstrate the use of an automated method of conducting shallow seismic surveys--an approach that represents a significant departure from conventional seismic-survey field procedures. Recent tests involving a second-generation mechanical geophone-planting device have shown that large numbers of geophones can be placed quickly and automatically and can acquire good data. In some easy-access environments, this device is expected to make shallow seismic surveying considerably more efficient and less expensive. Another element of our research plan involves monitoring the cone of depression of a pumping well that serves as a proxy location for fluid-flow at a contaminated site. In May 2001, we collected data from a well site at which drawdown equilibrium had been reached. That information is being interpreted and evaluated. The development of noninvasive, in-situ methods such as placing geophones automatically and using near-surface seismic methods alone or in concert with ground-penetrating radar to identify and characterize the hydrologic flow regimes at contaminated sites supports the prospect of developing effective, cost-conscious cleanup strategies for DOE and others.
