Three dimensional ERT image showing an array of many surface electrodes (red dots on the image block). In this case, a grid of electrodes was used to characterize the locations of resistivity features, likely voids or fractures in shallow basalt layers using a 1 x 1 m grid of electrodes.Proposed well and surface line layout for a Permeable Reactive Barrier showing surface lines in green and wells with red electrodes and yellow labels.
Monitoring soil saturation during air sparging activities. Data collection at an arsenic-contaminated Permeable Reactive Barrier site.
3-D images, created with MPT inversion software, of the PRB at East Helena showing the barrier resistivity and IP from 7 to 15 m below ground surface. Electrode locations are shown as red dots.
