An Electrical Approach to Groundwater Exploration

Rutgers University: Electrical Environmental Geophysics
Abstract 
Nuclear Magnetic Resonance (NMR) is an upcoming technique that is actively being researched for the exploration of groundwater. To aid in this research, a series of Electrical Resistivity (ER) measurements were conducted to confirm the location of the groundwater table. Upon collection of data, the results were inverted using a publicly available inversion software package. Using the Wenner array, an area of lower resistance was detected between 2 to 5 meters (m). Subsequent research indicates this is within the expected depth to groundwater of 4 to 8 m. In addition to the Wenner array, a Dipole-Dipole dataset was collected from the same electrode line as the Wenner and one additional electrode line. The resulting inversion indicated the lower resistance area is between 0 to 5 meters. Elevated levels of data error and due to substantial surface ponding it is unclear if the resulting lower resistance zone is a result of shallower groundwater, poor data, or the results of infiltrated surface water. Further data collection to confirm the location of groundwater is warranted.

Comment [LDS1]: VERY NICE EFFORT ON THIS. GOOD ASSESSMENT OF THE DIFFERENCES BETWEEN THE DIPOLEDIPOLE AND WENNER DATASETS. YOUR ASSESSMENT OF THE ERRORS WAS NOT CLEAR TO ME – I.E. HOW YOU ACTUALLY INCORPORATED THE ERRORS INTO THE INVERSION. OTHER THAN THAT, WELL RESEARCHED AND VERY NICELY PRESENTED GRADE – 94% Comment [LDS2]: Title is non-specific. It would have been better to be something much more focused on your study. Comment [LDS3]: Very nice abstract

Introduction 
Electrical Resistivity (ER) measurements have been used for many years to aid in the exploration of natural resources (Wenner 1916). In 1942, Gus E. Archie modeled observed conduction to soil properties. This relationship, commonly referred to as Archie’s law, is:

however, the general principles of...
