AFP6 Geologs Archive
The Air-Force Plant No. 6 (AFP6) Geologs archive is a data repository for borehole geophysical logs, lithologic
logs, heatpulse-flowmeter measurements, and packer-test data used to characterize
the fractured-crystalline rock aquifer system at Air Force Plant No. 6, located in Marietta, Georgia. The data files can be retrieved
using the table and map links below. The Featured Borehole Logs section
provides additional information on the results of borehole logging and hydrogeologic

Featured Borehole Logs
SCT-1 is located east (downgradient) of Air-Force Plant No. 6 on property owned
Polytech Institute. It is one of several "off-site" monitoring
wells that are used to monitor ground-water conditions near Rottenwood Creek.
This well is characterized by a highly-weathered and permeable
transition zone just below the casing and discrete permeable foliation-parallel parting planes in the
deeper bedrock. Optical images collected from this borehole indicates differential
weathering parallel to
foliation and compositional layering is much stronger than weathering along joints.
The borehole geophysical logging methods used at AFP6 are described in the following
