There
have been a number of cases, particularly in the subsurface vadose zone, where
contaminants have moved much more quickly than expected.
Recent examples include the apparent movement of radionucleides from
storage tanks into the groundwater at the Hanford
reservation and at the
Nevada Test Site. The
establishment of an effective monitoring methodology, particularly a
cost-effective one, is required. This
project will develop a geophysical method that uses a combination of electrical
and magnetic field measurements to provide high-quality, three-dimensional
images of the subsurface. To do this
in a cost effective fashion, the method is designed to make use of existing
wells including metal cased ones. Phase
I will develop a model to provide optimal configurations of electrical and
magnetic sensors, test the ability of the method to obtain measurements through
metal well casings, and determine the design criteria for a field system.
To compliment these theoretical studies, tests with commercially
available magnetic sensors will be performed to determine if the method will
work inside metal casings and the level of accuracy that can be achieved.
Commercial Applications and Other Benefits as described by the awardee: The technology should provide for the cost effective monitoring of many sites that are not accessible to any commercial technology. For example, the method could be used in the Tank Farms at the Hanford Reservation using existing metal cased wells.
