Enviroprobe performed a soil resistivity testing with Wenner Array 4-point Method in Moorestown, NJ. This method is the most used test method to measure the resistivity of soil for electrical grounding design. The Wenner array consists of a line of four equally spaced electrodes. Current is injected through the outer electrodes and potential is measured between the inner electrodes. The testing utilized an Advanced Geoscience Inc. (AGI) SuperSting R8 resistivity system and was done in a perpendicular pair at the test location using the standard traverse setup with the maximum “a” spacing as 100'.
