When explora- tion targets are shallow, such as CBM, the extraction of the resource may impact potable ground water supplies.

The rapid growth of CBM develop- ment has posed difficult challenges for the impacted communities. One of those conflicts is in the extraction and disposal of produced water. CBM wells are typically shallow, and are often completed into the same for- mations that supply ground water to wells. Before CBM can be pro- duced, the hydraulic pressure of the reservoir must be reduced by partial dewatering of the aquifer.

The SP method utilizes naturally occurring electrical poten- tials. These potentials result, in part, from the electrokinetic effect, in which streaming potentials are generated by the drag of excess charge between ground water and the mineral surface. Therefore, changes in the electrical potential during hydraulic pumping serve as a proxy for changes in ground- water flow patterns and hydraulic gradient (Bogoslovski and Ogilvy, 1973; Revil and others, 2003; Rizzo and others, 2004). A surface array of non­polarizing electrodes will be used to map the electrical potential at regu- lar time intervals during the pumping test. Numerical modeling will be used to integrate the SP and hydraulic test data to solve for permeability struc- ture. By utilizing the electrical signal of ground-water movement, I hope to develop a truly interdisciplinary approach to characterizing structurally complex aquifers

Through numerical modeling, these time-lapse electrical potential data will be used in conjunction with water- level measurements to construct a high-resolution model of the piezomet- ric surface during and following pump- ColoradoGroundWater.org
