13. ABSTRACT (Maximum 200 words)
Ongoing investigations of the permafrost and ground water conditions in the north-central area of the Fort
Wainwright, Alaska, cantonment, north of the Chena River, show the hydrogeology of the site to be extremely
complex. Permafrost, being impermeable and discontinuous, controls the distribution and dimensions of
ground water aquifers to a great degree. Aquifers are above, below, and adjacent to permafrost, and in some
locations are within unfrozen zones surrounded by it. This complexity makes it difficult to predict the direction
and velocity of ground water flow, as well as its seasonal and annual variability. Data have been obtained from
ground-penetrating radar surveys, borehole logs, and ground water instruments. They have then been com-
bined with interpretations of aerial photographs and ground observations to delineate the permafrost and
aquifer distribution. They have also been used to develop conceptual hydrogeological models of the area. This
information is necessary to remediate ground water contamination, while furthering the basic understanding
of aquifer distribution and ground water flow in discontinuous permafrost terrain.
