EXECUTIVE SUMMARY
Recent and historical water table levels at the R Reactor Seepage Basins (RRSBS) suggest
that a “perched” water table may exist directly beneath the RRSBS based on regulatory
documentation and groundwater modeling. Additional studies were conducted in the summer
of 1999 of the shallow groundwater system to determine if the water beneath the RRSBS is
actually perched or whether the shallow water table is in direct communication with the
underlying “transmissive zone”. Direct Push or Cone Penetrometer Technology (CPT) was
used to investigate the shallow water table beneath the basins. CPT soil moisture and
resistivity tests combined with CPT lithologic data (tip, sleeve, friction ratio, and pore
pressure) were performed at 10 locations. The CPT pushes were pushed to approximately
105’ to obtain a saturation profile from the surface to the top of the “transmissive zone” in
the Upper Three Runs Aquifer. Shelby tube samples were taken with the soil moisture
analysis to validate and confirm moisture percentage.
Upon completion of the field investigation the following sources of data were integrated to
determine the characteristics of the shallow water table:
. CPT data (moisture%, resistivity data, pore pressure, tip, sleeve, and friction ratio)
● Permeability data
● Water level and potentiometric data to determine head relations
. Contaminant Data
All the data indicate that perched water conditions occur on a seasonal basis during extremely
wet periods as were experienced in the spring of 1998. There is significantly less mounding
of the water table beneath the RRSBS with water levels being 10–15 feet lower during 1999.
This is due to the “draining” of the upper water table due to dry conditions in the summers of
both 1998 and 1999 along with the effects of the asphalt cover over the basins. CPT data
further indicates that the 1998 water levels were located on top of silty and clayey layers in
March 1998. In addition, the confining-like characteristics of the “A” and “AA” horizons
and the positive potentiometric surface of the underlying “Transrnissive” zone impede
vertical movement of groundwater from the surface to the “transmissive zone”. This
interpretation is corroborated by the extent of Sr-90 contamination in the upper water table
DU zone &d the absence of Sr-90 contamination in the lower DL (“transmissive” zone).
Therefore, contamination from the Principal Threat Source Material (PTSM) associated with
the RRSBS will not easily migrate into the underlying “transmissive zone”.

1.0 Introduction
Recent and historical water table levels at the R Reactor Seepage Basins (RRSBS) (Figure 1)
suggest that a “perched” water table may exist directly beneath the basins. Recent regulatory
documentation (WSRC, 1998) and groundwater modeling (Jones and others, 1998) both
indicated that additional study of the shallow groundwater system is needed to determine if
the water beneath the RRSBS is actually perched or whether the shallow water table is in
direct communication with the underlying “transmissive zone”. The understanding of the
shallow water table in relation to the hydrology of the area is essential for the ongoing
feasibility study for the waste unit. Whether or not the water table is perched may impact the
remedial alternative selection for the Principal Threat Source Material (PTSM). If the water
table is “perched”, then it is part of the soil column above the “Transmissive zone” (which
would become the first viable aquifer zone). If this is the case soil leachability would be
considered from the contaminant source to the “transrnissive zone for the purpose of remedial
technology selection”. The focus of this report is the summer 1999 investigation of the
shallow groundwater system using cone penetrometer technology (CPT) characterization
methods to determine if the water table is perched beneath the RRSBS.
The characterization plan for this study was documented in a Workplan Addendum outlining
additional field characterization for the RRSB Workplan/RFI/RI for the RRSB (WSRC,
1999a).
1.1 Hydrogeology and Extent of Contamination
There are four hydrostratigraphic units that are important to contaminant migration. Figure 2
is a conceptual hydrogeological model for the RRSB area. The seepage basins are located in
undifferentiated surface soils of varying thickness. The “A” and “AA” horizons immediately
beneath the seepage basins, and correspond to the Upland Unit and Tobacco Road Formation.
The “A” and “AA” horizons both are similar to confining units with relatively low hydraulic
conductivities (average 1.Ox10-7 crnlsc and 1.Ox10-6 cmlsec, respectively). The
“Transmissive” zone underlies the “AA” horizon, and correlates to the Irwinton Sand of the
Dry Branch Formation. This zone has relatively high hydraulic conductivity averaging
1.Ox10-4crnlsec.
Groundwater is present in the “A” and “AA” horizons and the “Transmissive” zone. The
hydraulic characteristics of the “A” and “AA” horizons are not well understood because these
strata behave more like confining units than aquifers. The vertical mobility of the
2 WSRC-TR-99-O0330, Rev. O, RRSB Soil Moisture and Resistivity Field Investigation with CPT
groundwater within these low permeability units is also not well understood. Figure 2
illustrates how the groundwater in the “A” and “AA” (DU) horizons is at similar head to the
potentiometric surface of the “Transmissive” zone (DL) to the west of the waste units. This
is supported by the water table surface of the “A/AA” and potentiometric surface of the
“Transrnissive” zone (Figures 3 and 4). In the area underlying the RRSBS the groundwater
surface associated with the “Transmissive” zone (DL) drops toward the “Old” R Area
Discharge Canal, which indicates the aquifer discharges into the canal. However, in the same
area the water table surface associated with the “AlAA” horizon (DU) is relatively flat lying
when compared to the “Transmissive” zone (DL) which suggests minimal connection
between the two water bearing units.
The majority of the Contaminants of Concern (COCS) associated with PTSM have not
migrated significantly within the vadose zone, and tend to remain within the contaminated
soils in the backfilled basins. However, a portion of the Sr-90 associated with the PTSM, has
migrated to the groundwater within the “A” horizon. Am-241, Pu239/240 are also
contaminant migration constituent of concern (CMCOCS) are therefore predicted to migrate
from the PTSM to the groundwater at activities above their respective maximum contaminant
level (MCL). The potential for migration of contaminants in the groundwater within the “A”
horizon, to deeper stratigraphic units, is dependent upon the connection between the water
bearing units. Therefore it is very important to have a good understanding of the hydraulic
characteristics of these hydrostratigraphic units, and the degree of connectivity of the units, to
make good predictions of contaminant transport. In addition, this information is critical to a
proper selection of remedial alternatives.
1.2 Field Characterization Methodology using the Cone Penetrometer Soil Moisture&
Resistivity Probe
Soil Moisture Probes were evaluated at the Savannah River Site in 1996 and 1997 (Argonne
National Laboratory, 1997) through the Site Characterization and Analysis Penetrometer
System. The soil moisture probe is used in conjunction with direct push technology to obtain
real-time data to measure subsurface volumetric soil moisture. Shelby tube samples are taken
with the soil moisture analysis to validate and confirm moisture percentage. In addition,
resistivity log profiles were used in conjunction with the soil moisture percentage
measurements. Based on prior studies conducted at the SRS, the soil moisture percentages
increase as the probe approaches the saturated zone, while the resistivity decreases with the
WSRC-TR-99-O0330, Rev. O, RRSB Soil Moisture and Resistivity Field Investigation with CPT 3
increase in water in the pore space of the sediments (WSRC, 1999, Argonne National Labs,
1997).
CPT soil moisture and resistivity tests combined with CPT lithologic data (tip, sleeve,
friction ratio, and pore pressure) were performed at 10 locations (Figure 5 and Table 1). The
CPT pushes were pushed to approximately 105’ through the undifferentiated surface soils,
“A” Horizon and “AA” Horizon to obtain a saturation profile from the surface to the top of
the “transmissive zone” in the Upper Three Runs Aquifer. The CPT pushes were terminated
at the top of the “Transmissive zone”. Two of the CPT pushes (RR-19A and 19-B) were
inside the RRSB fence (Figure 5), and required RCO/HP coverage. The locations within the
RRSB fenced area were chosen based on the RRSB RFI/RI characterization work that
delineated the extent of contamination (Figure 6). The locations are in non-contaminated
areas within the fence (Figure 5 & 6).
The remaining 8 pushes were completed outside the fence and did not require RCO/HP
coverage (Figure 5). All of the locations are being done near existing lithologic pushes to
maximize hydrogeologic data in the area for interpretive purposes. Shelby tubes were
collected at 3 locations for soil moisture percentage and porosity. Shelby tube samples were
collected, sealed, and stored according to WRSC-3Q5.

on 7/1/99. Details of the daily activities
connection problems required repeating Iseveral of the pushes to ensure quality data was collected. Other than the electrical m
malfunctions, the remaining field work went smoothly. Appendix B contains plots of the 10
pushes with sleeve and tip stress, friction ratio, pore pressure, resistivity, and volume percent I
moisture plotted.
Shelby Tube Samples were collected at RR-3, RR-7, and RR-9. Table 2 summarizes the
results. Figures 7 -9 illustrates the sample locations and percentages in relation to the CPT
data and June water levels at nearby RPC-3 DU and DL. Soil samples were taken in clear B
tubing in four foot sections. The samples were then examined to determine where to take the
sample based on the CPT results and lithologic type. Samples were analyzed by LAW I
Engineering and Environmental Services in Atlanta, GA for Grain Sieve Wash 200 (ASTM
D422) and volumetric soil moisture content, density and porosity (EM1 110-2-1906). IAppendix C provides the detailed results from LAW Engineering and Environmental
Services.
Samples were taken at RR-3 beginning at a depth of 5 feet. A total of 10 samples were taken
ending at 101.5 feet. Again, samples were taken based on the lithology and in relation to the 9
response on the CPT moisture percentage curve (Figure 7). Generally, the results match well
with the laboratory results and the predicted moisture from the CPT probe. In the upper 30I
feet of RR-3 there is variability of approximately 15% moisture percentage in interbedded
sandy, silty and clayey sediments. In the lower portion of RR-3 the moisture percentage is
relatively stable with variability of approximately 10Yo.

Samples were taken at RR-7 beginning at 3 feet. A total of 6 samples were taken ending at
23 feet. The agreement is good for the correlation between the laboratory values and CPT
probe predictions for soil moisture. There is approximately 15% variability in the laborato~
values in the highly interbedded sandy, silty, and clayey sediments in the upper 30 feet of ,
RR-7. There is excellent correlation between the lithology defined by the friction ratio with
the pore pressure response, resistivity and moisture percentage curves (Figure 8).
Samples were taken at RR-9 beginning at 6.0 feet. A total of 6 samples were taken ending at
27 feet. Again, agreement is relatively good for the correlation between the laboratory values
and CPT probe predictions for soil moisture. The sediments are not as highly interbedded in
RR-09 as in RR-03 and RR-07. This is reflected in the higher moisture percentage values
around 15 feet. Correlation is good between the Iithology defined by the friction ratio with
the pore pressure response, resistivity and moisture percentage curves (Figure 9).
Figure 10 illustrates an east-west cross-section labeled A – A’ (traverse location on Figure 5)
through sample points RR-9, RR- 19A, and RR-3. The cross-section also illustrates the water
table DU elevations and the “Transmissive” zone potentiometric surface DL elevations in
March 1998 and June 1999. This relation will be discussed in the next section.
Figure 11 is a 3-dimensional grid of the soil moisture probe data over the RRSB data. The
grid illustrates that the lower percent moisture is near the surface in the surface soils and “A”
horizon and the higher percent moisture is correlative with the elevation of the
“Transmissive” zone potentiometric surface. The moisture percentage is relatively stable
below this surface.
3.0 Interpretation
The purpose of the study was to determine if “perched” water conditions exist in the shallow
water table system at the RRSBS, Upon completion of the soil moisture probe and resistivity
study other data was combined to better resolve and understand the characteristics of the
shallow hydrogeology.
The RPC wells that rim the RRSBS (Figure 5) were installed in March 1998. During
installation the region experienced unusually heavy rains from the “El Nine” effect of Pacific
Ocean heating. Upon completion of the well installation water table measurements indicated
an extremely high water table surface, sometimes within 0.5 feet of the ground surface
(Appendix D and Figure 3). The monthly water table measurements begun in August 1998
WSRC-TR-99-O0330, Rev. O, RRSB Soil Moisture and Resistivity Field Investigation with CPT 7
continue to be collected. The water levels have dropped significantly since March 1998.
Appendix D contains the hydrography for the RPC wells around the RRSBS. Figures 7 – 9
illustrate the water level differences experienced from March 1998 until June 1999 at RPC-
3DU/RR-03, RPC-7DU/RR-07, and RPC-9DU/RR-09. At all three locations the water table
has dropped significantly ranging from 10 – 15 feet with very small differences currently
observed between the upper DU “A/AA” horizon water table screen and the lower DL
“transmissive” zone screen of 2 – 5 feet.
Figures 3 and 4 and Figures 12 and 13 illustrate the March 98 and June 99 water table surface
for the DU screens and DL screens, respectively. Notice, that there is significantly less
mounding underneath the basins in June 99 for the upper water table surface in the DU
screens. This is interpreted to be from the “draining” of the upper water table due to dry
conditions that have been experienced in the summers of both 1998 and 1999 and the effects
of the asphalt cover over the basins. The soil moisture probe data supports this interpretation.
Figures 7 (RR-03) and 8 (RR-07) illustrate that in March 1998 the DU screen zone water
levels were located on top of silty and clayey layers and therefore were exhibiting perched
conditions during that timeframe. During 1999 the DU water levels have dropped and have
stabilized with very little head separation between the DU & DL water elevations. The DU
water levels appears to have little effect on vertical groundwater movement. This is
consistent with the vertical permeabilities and horizontal groundwater flow velocities cited in
the August 1998 RFI/RI/BRA (WSRC, 1998). The average vertical permeability for the “A”
horizon is l. OXIO-Gcrn/sec and the annual horizontal movement is approximately 9.2
cmlyear. This coupled with the positive head conditions of the underlying “transmissive
zone” support the that the PSTM will not easily migrate into the underlying transmissive
zone.
The soil moisture probe CPT data (volume moisture 910,resistivity data, pore pressure, tip,
sleeve, and friction ratio) coupled with the water level data indicate strongly that perched
water conditions occur on a seasonal basis during extremely wet periods as were experienced
in March 1998. However, due to the confining like characteristics of the “A’ and “AA”
horizons and the positive potentiometric surface of the underlying “Transmissive” zone the
vertical movement of groundwater from the surface to the “transmissive zone” is not likely.
This interpretation is corroborated by the extent of Sr-90 contamination in the upper water
table DU zone and the absence of Sr-90 contamination in the lower DL (“transmissive” zone)
as reported in the RFI/RI/BRA (WSRC, 1998).

4.0 Summary
Recent and historical water table levels at the RRSBS suggested that a “perched” water table
may exist directly beneath the RRSBS based on regulatory documentation (WSRC, 1998) and
groundwater modeling (Jones and others, 1998). Additional studies were conducted in the
summer of 1999 of the shallow groundwater system to determine if the water beneath the
RRSBS is actually perched or whether the shallow water table is in direct communication
with the underlying “transrnissive zone”.
Direct Push Technology was used to investigate the shallow water table beneath the basins.
CPT soil moisture and resistivity tests combined with CPT lithologic data (tip, sleeve,
friction ratio, and pore pressure) were performed at 10 locations. The CPT pushes were
pushed to approximately 105’ through the undifferentiated surface soils, “A” Horizon and
“AA” Horizon to obtain a saturation profile from the surface to the top of the “transmissive
zone” in the Upper Three Runs Aquifer. Shelby tube samples were taken with the soil
moisture analysis to validate and confirm moisture percentage.
Upon completion of the field investigation the following sources of data were integrated to
determine the characteristics of the shallow water table:
. CPT data (volume
ratio)
. Permeability data
moisture 9ii, resistivity data, pore pressure, tip, sleeve, and friction
● Water level and potentiometric data to determine head relations
. Contaminant Data
All the data indicate that perched water conditions occur on a seasonal basis during extremely
wet periods as were experienced in March 1998. There is significantly less mounding of the
water table beneath the RRSBS with water levels being 10 –15 feet lower during 1999. This
is interpreted to be from the “draining” of the upper water table due to dry conditions in the
summers of both 1998 and 1999 and the effects of the asphalt cover over the basins.
Perched water is also indicated by the lithologic data. Careful examination of the CPT data
and water level data illustrate the March 1998 DU screen water levels were located on top of
silty and clayey layers in March 1998.
WSRC-TR-99-O0330, Rev. O, RRSB Soil Moisture and Resistivity Field Investigation with CPT 9
Furthermore, the confining like characteristics of the “A” and “AA” horizons (based on
permeability data) and the positive potentiometric surface of the underlying “Transmissive”
zone impede vertical movement of groundwater from the surface to the “transrnissive zone”.
This interpretation is corroborated by the extent of Sr-90 contamination in the upper water
table DU zone and the absence of Sr-90 contamination in the lower DL (“transmissive” zone)
as reported in the RFI/RI/BRA (WSRC, 1998). Therefore, contamination from the PTSM
associated with the RRSBS will not easily migrate into the underlying “transmissive zone”.
5.0 Recommendations
Monitoring of the R Area wells water elevations on a monthly basis should be continued. In
addition, individual monitoring of selected wells should be initiated. Electronic
instrumentation that can measure the water levels on a timed interval should be considered.
This would allow for rain events to be monitored to verify the perching of water on the silty
and clayey layers near the ground surface.
The new piezometers that were installed to monitor water levels near the R-Area Canal
should be measured on a monthly basis. In addition, these wells should be considered for
individual monitoring as well as described above.
Multi-well pumping tests are planned at the RPC-1 and P-20 cluster during FYOO. The
information from these tests should be integrated into the soil moisture/resistivity field
characterization results to further understand the shallow hydrogeology and its relation to
contaminant migration of the PTSM to the subsurface beneath the RRSBS.
