Geoprobes were developed by the environmental industry to collect water, gas and soil samples from contaminated sites at shallow depths (10-40 meters), with a minimum of environmental disturbance. A modified Geoprobe was used to collect bottom hole temperatures, and attempt to collect geothermal water samples, at the McGee Mountain geothermal property in Humboldt County, Nevada. A total of 23 holes were probed in five days for a cumulative total of 857.5 ft. at 21 sites at the project area. The probed holes ranged in depth from a maximum of 75ft to a minimum of 10ft and averaged 37.3ft. The average temperature of the 23 holes was 18.9 degrees C, corrected(from an average of 23.8 degrees C, uncorrected) with a range of 42.0 degrees C (site MMTG#19) for a maximum and 12.0 degrees C, corrected (site MMTG#1b). Since the water table was not encountered in any hole, no down-hole water samples were collected. However, water sampling was conducted at nearby springs and wells. PDF file, 15 MB file size.

This shapefile contains location and attribute data for a Geoprobe temperature survey conducted by Geothermal Technical Partners, Inc. during 2010. The purpose of direct push technology (DPT) probe activity at the McGee Mtn. Project, Nevada was to 1) determine bottom hole temperatures using nominal 1.5 inch probe tooling to place resistance temperature detectors (RTD) and 2) take water samples, if possible, to characterize the geothermometry of the system. A total of 23 holes were probed in five days for a cumulative total of 857.5 ft. at 21 sites at McGee Mountain. The probed holes ranged in depth from a maximum of 75 ft to a minimum of 10 ft and averaged 37.3 ft. The average temperature of the 23 holes was 18.9 degrees C, with a range of 12.0 degrees C at site MMTG#1b to 42.0 degrees C at site MMTG#19. . No water was encountered in any of the probed holes, with the exception of MMTG#10, and no water was collected for sampling.
