*Hydrogeologic Units Defined
Taken from the 1213012003 Albemarle County Hydrogeologic Assessment Phase ii —
Groundwater Availability and Sensitivity Assessment with Proposed Groundwater Assessment
Standards. Prepared by ENSAT Corporation, Culpeper, VA.
The process of investigating groundwater availability at the County -wide scale involved identifying distinct
hydrogeologic units and comparing the units based on groundwater availability characteristics for which data
could be obtained. Each hydrogeologic unit shares some common characteristics with regard to geology,
soils, and topography, although there is quite a bit of variability within each unit.
Nine hydrogeologic units were identified across the County, as follows, and as shown on the Albemarle
County Hydrogeologic Unit Map (Figure 2).

Figure 2 - Albemarle County Hydrogeologic Unit Map
Blue Ridge West-IW: This unit lies primarily
on the steep eastern slopes of the Blue Ridge
Mountains and is dominated by the Myersville
and Parker Soils, and to a lesser extent the
Chester. Slopes range from 2-60%. These soils
are residual in nature. The Myersville soils are
derived from weathered volcanic metamorphic
rocks (greenstone) and Parker and Chester soil
series are derived from weathered granite and
granite gneiss. These soils are considered to be
relatively deep and well drained.
Blue Ridge East-IE: The Blue Ridge East unit
overlies volcanic greenstone rock and represents
the eastern limb of the Blue Ridge Anticlinorium.
The area is characterized by the presence of a
prominent ridge and trends generally northeast
within the otherwise rolling piedmont landscape.
Portions of this ridge are known locally as Green
Mountain, Carters Mountain, and the Southwest
Mountains. This area is dominated by the Rabun
and Myersville soils and to a lesser extent, the
Catoctin. The Rabun soil series is deep and well
drained and like the Myersville soil series is
formed from weathered greenstone. The
Catoctin soil series is considered to be
moderately deep and well drained and is also
formed from weathered greenstone.
Colluvial Fans -II: The Colluvial Fan unit lies at
the base of the eastern slopes of the Blue Ridge
Mountain and is characterized by relatively steep
drainage swales that extend to more gradual sloping conditions. The area includes a series of
intermittent drainages that include ephemeral drainage ways. Many of the intermittent drainages
become perennial streams as this area includes stream bottom valleys. A significant portion of the unit
area consists of transported soils including the Braddock and Thurmont. These soils are formed in
colluvial and alluvial materials found on colluvial fans and terraces and are the product of weathered
granite, granodiorite, granite gneiss, and greenstone. Both of these soil series are deep and well
drained with slopes ranging from 2-25%. Residual soils including the Hayesville and the Chester are
also abundant. These soils are also deep and well drained and are formed on upland slopes from
weathered products of granite and granite gneiss. Slopes of these soils typically range from 2-45%.
Bedrock geology consists largely of metagranitic rock of the Blue Ridge Basement Complex and
metasedimentary, metaconglomerate and phyllite of the Swift Run Formation. The accumulation of
transported soils (colluvial and alluvial) can form "cappings" over residual soils and parent material,
which can add to the overall thickness of the overburden.
4. Piedmont Foothills -III: The Piedmont Foothills unit is characterized by rolling upland to relatively
steep topography. Soils within this area dominated by the Hayesville, Ashe and Chester soil series
which are moderately deep to deep, and generally well drained. These soils are found on the piedmont
upland and foothills of the Blue Ridge Mountain on slopes ranging from 2-45%. These soils are formed
from weathered granites and meta -granites of the Blue Ridge Basement complex. The Piedmont
Foothills area is bifurcated by Hydrogeologic Unit IV (Lynchburg).
5. Lynchburg -IV: The Lynchburg unit is characterized by a relatively narrow band that trends in a
northeast direction and includes a relatively long segment of the Mechums River valley. Soils within this
unit are dominated by the Hazel and to a lesser extent by the Elioak and Glenelg soils. The Hazel soil
series are moderately deep and well drained and are formed in the weathered products of
metagraywacke sandstone and mica schist. Hazel soils lie on uplands and their slopes range from 7-
45%. The Elioak soil series are deep and well drained and are formed in the products of weathered
micaeous metamorphic rock. Slopes of the Elioak range from 2-25%. The Glenelg soils are also deep
and well drained and are formed in the weathered products of quartz mica schist. Slopes of the Glenelg
range from 2-45%. The area is underlain primarily by the Lynchburg Formation and/or the Mechums
River Formation which consists largely of metagraywacke, meta sandstone, and graphitic schist.
6. Ragged Mountain-V: The Ragged Mountain unit is characterized by mountainous terrain located in the
southwestern portion of the County and is underlain by the metagranitic rocks of the Blue Ridge
Basement Complex. The soils in the area are dominated by the Chester, Hayesville, Ashe, and Parker
soil series. These soils are derived from weathered granite and granite gneiss and are deep and
excessively well drained. These soils range in slope from 2-45% with some slopes up to 60 percent in
the Parker soils.
7. Candler -VI: The Candler unit is underlain primarily by the Candler formation. Bedrock geology includes
phyllites and to a lesser degree laminated metasiltstone. Soils underlying the unit area are dominated
by the Manteo and Nason series. Manteo soils are shallow and somewhat excessively drained. The
Manteo soils are formed in the weathered products of sericitic schist/phyllite on uplands and range in
slope from 2-45%. The Nason soil series are deep and well drained and are also formed in the
weathered products of sericitic schist/phyllite. The Nason soils are formed on uplands and range in
slope from 2-25%.
8. Newark Basin-VII: 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% deep to moderately deep and well
drained. Slopes range from 2-25%.
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 much smaller area of the Barboursville Basin located in the northern
portion of the County.
9. Piedmont Proper-VIII: The Piedmont Proper unit is characterized by gently rolling piedmont
topography. The bedrock geology underlying the unit is mapped as Metagraywacke, quartoze schist,
and melange. Soils in the unit area are dominated by the Nason and the Manteo in nearly equal
percentages. Although these same soils also dominated the Candler unit, it should be noted that the
Manteo soils were nearly twice as prevalent as compared to the Nason. Manteo soils are shallow and
somewhat excessively drained. The Manteo soils are formed in the weathered products of sericitic
schists/phyllites on uplands and range in slope from 2-45%. The Nason soil series are deep and well
drained and are also formed in the weathered products of sericitic schist. The Nason soils are formed
on uplands and range in slope from 2-25%.
10. Barboursville -IX: This unit exists in only a small portion of the County at the area where Route 20
enters Orange County. Evidently this hydrogeologic unit was small enough that it did not factor into the
ENSAT report and therefore does not have a description like the other units. You can see an unlabeled
delineation of this unit in the map (Figure 2) along the northern County boundary near the right-hand
side.
