Mundell was retained to perform a multi-technique borehole geophysical survey to determine flow conditions in within a limestone bedrock aquifer below a former manufacturing facility. These downhole geophysical techniques were used as a preliminary step in an investigation to locate and evaluate the water quality within the bedrock fracture zones beneath the facility……Read More »

Volumetric Analysis of Aggregate Resources Using Geophysics
Mundell collected several resistivity cross-sections over a 20 acre site to approximate the volume of aggregate resources present. Only two days of data collection allowed the client to make an informed decision in regards to mining the site……Read More »
Quantification of Aggregate Resources Using Geophysics
Mundell was contracted to quantify the extent of the sand and gravel reserves located beneath an 18 acre site in central Indiana. The seven resistivity profiles collected across the site indicated not only large volumes of aggregate resources, but allowed for the identification of interbedded clay lenses that would reduce the commercial value of the property from the mining perspective. This information, collected in only two days of field work, allowed the client to evaluate the real commercial value of the property……Read More »
Use of Geophysical Surveys for Archaeological Excavation Planning
Mundell used multiple geophysical methods to evaluate a site of suspected Anasazi ruins prior to an archaeological survey. The use of multiple geophysical techniques allowed for the cross correlation of anomalous areas, enhancing the likelihood of finding features of significance, which included a pueblo with connecting rooms, several deep storage pits, and three burials……Read More »
Conductivity Mapping to Locate a Sand and Gravel Aquifer
Mundell performed an EM-34 conductivity survey over a 66 acre site to confirm the result of 8 preliminary test borings for an industrial water well. The test borings indicated very little sand and gravel resources were present. After performing the survey and analyzing the results, Mundell’s geophysical department showed the borings were just advanced in poor locations and abundant sand and gravel were indeed present beneath the site……Read More »
