In a groundwater assessment done for the Albemarle County, ENSAT
Corporation divided the county into `hydrologic units'. Below is ENSAT's
description of the unit in which lies the property:
The Newark Basin unit is characterized by low relief topography,
which exists over Mesozoic basin geology. The unit is underlain by
the Newark Supergroup which consists of sandstones, siltstones and
shales. Soils within this area are dominated by the Totier, Rapidan,
and Penn series. The Totier soil series are deep and well drained and
are formed from weathered Triassic red shale. These soils are found
on uplands and range in slope from 2-15%.
The Rapidan soil series are also deep and well drained and are formed
in weathered products of Triassic conglomerate. The Rapidan, like
the Totier, are found on uplands and range in slope from 2 -25 %. The
Penn series are moderately deep and well drained and are formed
from the weathered products of Triassic red shale. The Newark Basin
hydrogeologic unit includes the Scottsville Basin located in the
southern portion of the County and a much smaller area of the
Barboursville Basin located in the northern portion of the County.
