Challenge
The Town of Remington, Indiana had been experiencing a water shortage in the early 2000s, and the existing water wells were not sufficient to satisfy current and future water needs. Rather than drill randomly chosen locations, Peerless-Midwest recommended that the Remington Town Council choose to conduct a geophysical survey over several hundred acres of land available for exploration on the outskirts of town. Mundell was subsequently subcontracted by Peerless to conduct the survey for the town’s groundwater resources.
Action
Mundell reviewed area borehole data and then performed an area-wide electrical resistivity survey to locate favorable areas to drill. Areas that were represented by clean sand and gravel were observed using EM34 profiles and 2-dimensional resistivity cross-sections, and additional information was gathered using borehole geophysical logging (see inset figure below) in several existing observation wells. With this information, Mundell identified several areas for possible production wells.
Results
Peerless drilled three of the recommended locations identified by Mundell and installed production wells in the two best locations (shown as stars on the above inset figure). Each new production well location encountered more than 20 ft of additional sand and gravel than had not been encountered before, and produced in excess of 800 gpm, double any prior well yields. The production wells are expected to yield at least 300 gpm under sustained pumping conditions.
