Results from Electromagnetic Surface Surveys to Characterize the Culebra Aquifer at the WIPP (Waste Isolation Pilot Plant) Site.

摘要

The hydrologic character of the aquifer contained within the Culebra Dolomite Member of the Rustler Formation is being studied. The hydrology studies suggest that permeable portions of this aquifer may be in the form of a strip(s) which cannot be described by a uniform (horizontal or radial) flow model. Electromagnetic surface geophysical surveys were conducted over an area south of the WIPP facility to provide information on aquifer boundaries, zones of high transmissivity, etc., for the 2-D and 3-D fluid flow modeling. Approximately 20 line km of controlled-source audiofrequency magnetotelluric (CSAMT) data were acquired covering an area of approximately 12.6 square km. 20 refs., 17 figs., 6 tabs.
