McGee Mountain Geoprobe Study, Humboldt County, Nevada
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.
