Table 2 Groundwater Level Data
I. Table 2 indicates that the depth to groundwater for monitoring well MW-11 is 29.26 feet (ft),
resulting in a groundwater elevation of 400.75 ft. However, the Groundwater Sampling
Form submitted for monitoring well MW-11 indicates that the well was dry at the time of
gauging and that no groundwater sample was collected. Please correct Table 2 to reflect
these dry conditions.
Table 3 Summarized Results of Laboratory and Field Analyses -
Groundwater Samples Collected September 2008
2. Table 3 indicates that the groundwater sample collected from monitoring well MW-12D in
September 2008 contained 4._89 milligrams per liter (mg/L) dissolved oxygen. However,the
Groundwater Sampling Forms indicate that the groundwater sample collected from
monitoring well MW-12D in September 2008 contained 4.69 mg/L dissolved oxygen. Please
clarify this discrepancy.
3. Table 3 indicates that the groundwater sample collected from monitoring well MW-171 in
September 2008 contained no detectable concentration of chloroform (at a laboratory
detection limit of25 micrograms per liter (µg/L)). However, the laboratory analytical results
indicate that the groundwater sample collected from monitoring well MW-171 in September
2008 contained 1,400 µg/L chloroform. Please clarify this discrepancy.
4. Table 3 indicates that the groundwater sample collected from monitoring well MW-17D in
September 2008 contained 1.1 µg/L 1, 1-dichloroethane. However, the laboratory analytical
results indicate that the groundwater sample collected from monitoring well MW-17D in
September 2008 contained 1.0 µg/L 1,1-dichloroethane. Please clarify this discrepancy.
5. Table 3 indicates that the groundwater sample collected from monitoring well MW-47 in
September 2008 contained no detectable concentration of trichloroethene (at a laboratory
detection limit of 0.5 µg/L). However, the laboratory analytical results indicate that the
groundwater sample collected from monitoring well MW-47 in September 2008 contained
1.9 µg/L trichloroethene. Please clarify this discrepancy.

RE: Results of September 2008 Groundwater Sampling/Analysis
and Updated Groundwater Modeling
Attached are results of groundwater sampling and mrnlysis conducted by Piedmont Geologic during September 2008
at tl1e Nortl1 Carolina State University (NCSU) Lot 86 site. The following materials are included.
• Site map;
• Tabulated monitoring-well construction details;
• Tabulated September 2008 groundwater level data;
• Tabulated summarized results of laboratory m1alysis of September 2008 groundwater analysis;
• September 2008 groundwater smnpling forms;
• Laboratory report for September 2008 groundwater samples.
As outlined in tl1e \Vorkplanfor Additional Groundwater Sampling/Analysis and Groundwater Modeling, dated July
JO, 2008, tlie September 2008 groundwater sampling/analysis event represents tl1e first of two interim groundwater""-'
sampling/analysis events planned for September 2008 and Jmmary 2009 utilizing 18 selected shallow, intermediate,
and deep monitoring wells. The purpose of tl1e activities is to evaluate and track short-term effects of site
groundwater recovery, including potential adverse downward migration of groundwater contaminants induced
tl1rough operation of tl1e site groundwater extraction (OWE) system. The September 2008 groundwater
sampling/m1alysis event also represents U1e first groundwater monitoring event following shutting down tlie. GWE
system deep (bedrock) recovery wells in June 2008. This was done in response to increased groundwater
contaminm1t concentrations in some deep monitoring wells between tlic May 2005 (prior to startup of U1e OWE
system in December 2006) and May 2008 (following startup of the GWE system) groundwater monitoring events.
Monitoring wells included in the interim groundwater san1pling/analysis progran1 are listed as follows witl1
rationale.

The September 2008 groundwater samples were collected using eiU1er tlic low-flow technique or tl1e traditional
purge and sample technique in accordance witl1 tl1e site groundwater sampling and analysis plan. Groundwater
samples were submitted to Pace Analytical Services, Inc. in Huntersville, North Carolina and analyzed for volatile
organic compounds (VOCs) by EPA Metl1od 6230. Site monitoring well MW-11_:"as dry during the September
2008 sampling event and, therefore, no groundwater sample was collected from tl1e well.
Rcsulls of laboratory analysis of September 2008 groundwater samples were used to update tl1e initial groundwater
graphical models presented in the August I, 2008 project memorandum (Results of Initial Groundwater Modeling).
The updated groundwater modeling was completed using the Surfer 8® modeling and contouring software,
. produced by Golden Software, Inc. Six groundwater data sets were incorporated into tl1e groundwater models, listed
as follows.
I. May 2005 groundwater potentiometric surface data for tl1e shallow, intermediate, and deep aquifers.
2. May 2005 groundwater chloroform concentration data for tl1e shallow, intermediate, and deep aquifers.
3. February 2008 groundwater potentiometric surface data for tl1e shallow, intermediate, and deep aquifers.
4. May 2008 groundwater chloroform concentration data for the shallow, intermediate, and deep aquifers.
5. September 2008 groundwater polcntiometric surface data for tl1c shallow, intermediate, and deep aquifers.
6. May-September 2008 ground waler chloroform concentration data for tl1e shallow, intermediate, and deep
aquifers.
Data sets no. 1 and 2 represent conditions prior to startup of tl1e site GWE system in December 2006. Data sets no.
3 and 4 represent tl1e first groundwater monitoring event following startup of tl1c site GWE system. The GWE
system was down during May 2008 ground waler potentiometric surface measurements. As a result, u,c previous

potcntiometric surface dak1 from February 2008 was used in the post-GWE system startup models. Data set no. 5
includes groundwater potentiometric surface data collected during a full-round of monitoring-well gauging
conducted as part of tlie September 2008 groundwater sampling event. Data set no. 6 incorporates tlic September
2008 groundwater analysis results, plus the previous, May 2008, groundwater analysis results for monitoring wells
tliat were not sampled during September 2008.
May 2005 groundwater potcntiometric-surface contour maps (attached) based on shallow, intermediate, and deep
monitoring-well data show apparent groundwater flow patterns under non-pumping conditions prior 10 startup oftlie
GWE system in December 2006. February 2008 groundwater potentiomctric-surface contour maps show
deflections of groundwater potentiometric-surface contours around GWE system recovery wells indicating
groundwater flow toward and capture by tlie recovery wells for all tliree aquifer zones. llie September 2008
groundwater potcntiometric-surfacc contour map for tlie shallow monitoring wells shows a similar pattern as tlie
February 2008 map for the sanie wells. The September 2008 groundwater potentiometric-surface contour maps for
tlic intermediate and deep monitoring wells appear similar to tl1e May 2005 maps for tlie same wells, indicating that
tlic pre-GWE system lateral flow patterns for these aquifer zones has been re-established. A comparison of
groundwater potentiometric-surfacc elevations for individual shallow, intermediate, and deep well clusters (Table 2),
such as MW-llS/MW-IJJ, MW-12S/MW-12I, MW-12D, and MW-16S/MW-16!/MW-16D, show upward
potentiomctric gradients between deep and shallow aquifer zones, indicating a desirable upward component of
groundwater flow.
A comparison of May 2005 and May-September 2008 groundwater chloroform isoconcentration contour maps for
the shallow monitoring wells indicates some shrinkage of the lateral extent of Ilic groundwater chloroform
distribution, especially in tlie core of the plume. A comparison of May 2005 and May-September 2008 groundwater
chloroform isoconccntration contour maps for the intermediate monitoring wells indicates an expansion of t11e
groundwater chloroform plume between May 2005 and May 2008, then a contraction of the plume between May
and September 2008. A comparison of May 2005 and May-September 2008 groundwater chloroform
isoconccntration contour maps for the deep monitoring wells indicates an apparent expansion of the groundwater
chloroform plume between May 2005 mid September 2008.
Following arc generalized trends in groundwater chloroform concentrations between tl1e May 2005, May 2008, and
September 2008 groundwater monitoring events. Chloroform was selected for the evaluation as the historically
most-prevalent groundwater contaminant generally detected at tl1e highest concentrations in site groundwater
samples. Monitoring wells witl1 detected chloroform concentrations between May 2005 mid September 2008 arc

included in tl1e May 2005, May 2008, and September 2008 groundwater monitoring events, all showed increasing
groundwater chlorofonn concentrations between May 2005 and May 2008, then decreasing groundwater chloroform
concentrations between May 2008 and September 2008. Of the four deep monitoring wells included in botl1 tlie
May 2005 and May 2008 groundwater monitoring events, three showed increasing groundwater chloroform
concentrations and one showed decreasing groundwater concentrations over that time pericxl. Of the four deep
monitoring wells included only in tl1e May 2005 and September 2008 groundwater monitoring events, two showed
increasing groundwater chloroform concentrations and two showed decreasing groundwater concentrations. Of the
two deep monitoring wells included in all tl1rce groundwater monitoring events, both showed increasing
groundwater chloroform concentrations between May 2005 and May 2008, one showed an additional increase in

groundwater chloroform concentration between May 2008 and September 2008, and one showed no significant
change between May 2008 and September 2008.
Tiw increasing trend in groundwater chloroform concentrations that was observed in tl1e intermediate monitoring
wells between May 2005 and May 2008 appears to have reversed between May and September 2008, concurrent
witl1 shutting down tlw deep GWE system recovery wells. Insufficient data is currently available to define deep
groundwater chloroform concentration trends witl1 respect to deep re,covery well operation. Furtl1er evaluation of
deep groundwater chloroform concentrations may be possible following tl1e planned January 2009 groundwater
monitoring event.

RE: Preliminary Evaluation of Results of May 2008 Groundwater Sampling/Analysis and
Recommendations for G \VE System Modifications
This memorandum provides a preliminary evaluation or tlie results of laboratory analysis of May 2008
groundwater samples and provides recommendations for modifications to the groundwater extraction
(GWE) system operational strategy at the Nortl1 Carolina State University (NCSU), Lot 86 Supcrfund site
in Raleigh, Nortl1 Carolina. Site groundwater sampling was completed in May 2008 by Piedmont
Geologic under contract witl1 NCSU.
Site monitoring well specifications arc attached as Table I, and tabulated results of laboratory analysis of
May 2008 groundwater samples are provided as Table 2. It is noted tliat site groundwater level data from
U1c May 2008 groundwater sampling event have been provided to NCSU under separate cover.
Site monitoring wells arc segregated into shallow (water-table saprolite), intermediate (deeper saprolite),
and deep (bedrock) divisions based on well deptl1 and screen interval, as follows.

Shallow 382-413 Residual soils/saorolite
Intermediate 355 -377 Saprolite/weatl1ered rock
Deep <345 Competent crystalline bedrock
The site GWE system incorporates a total of 17 groundwater recovery wells. Thirteen of tl1esc are shallow
groundwater recovery wells, ranging in deptl1 from approximately 50 to 80 feet below grade
(approximately 378 to 345 feet NGVD) and screened in saprolite. The remaining four are deep
groundwater recovery wells, ranging in depU1 from approximately 118 to 152 feet below grade
(approximately 310 to 265 feet NGVD), and screened in bedrock. Pump intake levels or 380 feet NGVD
for shallow recovery wells and 370 feet NGVD for deep recovery wells were selected d_uring tl1c system
design phase wiU1 tl1e intention to maximize induced groundwater flow from deeper to shallower aquifer
zones.
Groundwater potentiomctric surface contour maps for U1e shallow, intermediate, and deep monitoring
wells are attached as Figures I U1rough 3. For each set of monitoring wells two contour maps arc

presented. One map represents potentiomctric surface contours under pre.pumping conditions,
represented by May 3, 2005 groundwater level data. The second map represents potentiometric surface
contours under pumping conditions on February 5, 2008. The maps demonstrate groundwater drawdown
and capture zones in the shallow, intermediate, and deep groundwater monitoring zones induced tJ1rough
operation of tl1e site GWE system. It is noted that tl1e GWE system was temporarily not operating during
U1e May 2008 groundwater gauging event, precluding a more updated evaluation of groundwater
drawdown/capture zones. However, previous evaluations (August 2007 and November 2007) have
demonstrated almost identical drawdown/capturc patterns in the groundwater monitoring zones,
indicating that these conditions have been consistently maintained during routine operation of the GWE
system.
Graphs of groundwater chemical of concern (COC) concentrations over time (since May 2002) for
shallow, intermediate, and deep monitoring wells are attached. Monitoring wells are included tliat; 1)
have been subjected to sampling/analysis since 2002, and 2) have had significant detected concentrations
of groundwater COCs. Benzene, chloroform, and 1,2-dichloropropane (1,2-DCP) arc included in tl1e
graphs as the most prevalently detected volatile organic compounds in tl1e historical site groundwater
samples.
Groundwater COC concentration versus time trends for shallow, intermediate, and deep monitoring wells
are described as follows.
SHALLOW MONITORING WELLS
Groundwater COC concentrations since May 2002 in U1e shallow monitoring wells have shown
combinations of generally increasing trends, generally decreasing trends, and fluctuating trends. Iri
general, monitoring wells showing decreasing trends, especially since May 2005 and startup of U1e GWE
system in December 2006, are located along tl1e perimeter of the site groundwater COC plume and
recovery well array. Monitoring wells showing increasing groundwater COC concentrations since startup
of the GWE system tend to be located toward tl1e interior of tl1e site groundwater COC plume and
recovery well array. These concentration trends would be expected due to shrinkage of tl1e COC plume
from groundwater recovery around tl1e plume perimeter and hulk-movement of groundwater COCs witl1in
U1c plume interior from tl1e COC source area (former surface impoundment). Groundwater COC
concentrations trends in individual shallow monitoring wells arc described as follows.
MW-2
Shallow monitoring well MW-2 is located near shallow recovery well RW-11 and between shallow
recovery wells RW-11 and RW-12. Groundwater COC concentrations in MW-2 have steadily decreased
since May 2002, witl1 a higher rate of decrease occurring since startup of the GWE system in December
2006.

2002.
INTERMEDIATE MONITORING WELLS
With only minor exceptions, groundwater COC concentrations in the intermediate monitoring wells,
which are screened toward Uie base of saprolite, above Uic bedrock surface, increased between May 2005
:md May 2008, concurrent witl1 startup of the GWE system in December 2006. This condition may reflect
downward migration of groundwater COCs in U1e saprolite aquifer induced U1rough pumping of the
shallow and/or deep recovery wells. Groundwater COC concentrations trends in individual intermediate
monitoring wells are described as follows.

2008. A similar increase in groundwater COC concentrations between May 2005 and May 2008 was
observed in adjacent shallow monitoring well MW-I 1.
MW-121
Intermediate monitoring well MW-121 is located near shallow recovery well RW-3, between shallow
recovery wells RW-2 and RW-3, and south of deep recovery wells DRW-C and DRW-D. Groundwater

MW-421
Intermediate monitoring well MW-421 is located north ofboU1 U1e shallow and deep recovery well arrays.
Groundwater COC concentrations in MW-421 fluctuated between May 2002 and May 2005, then
increased sharply between May 2005 and May 2008, concurrent witl1 startup of the GWE system.
DEEP MONITORING WELLS
All U1ree deep monitoring wells tlrnt have been routinely sampled since May 2002 showed increasing
groundwater COC concentrations between May 2005 and May 2008, concurrent wiU1 startup of the site
GWE syslcm. As described above for the intermediate monitoring wells, this increase in groundwater
COC concentrations may re11ecl downward migration of groundwater COCs from tl1c saprolitc aquifer to
U1e bedrock aquifer induced U1rough pumping of UIC deep recovery wells. Groundwater COC
concentrations trends in individual deep monitoring wells are described as follows.
MW-35D
Deep monitoring well MW-35D is located to tl1e souU1 of deep recovery wells DRW-A and DRW-B and
east of shallow recovery well RW-9. Groundwater COC concentrations in MW-35D have steadily
increased since June 2004, wiU1 a higher rate of increase occurring since startup of tl1e GWE system in
December 2006.
MW-36D
Deep monitoring well MW-36D is located soutl1 of the deep recovery well array and midway between
shallow recovery wells RW-10 and RW-13. Groundwater COC concentrations in MW-36D have
fluctuated broadly since May 2002, witl1 a sharp increase observed between May 2002 and May 2008,
concurrent wiU1 startup of the GWE system.
MW-41D
Deep monitoring well MW-41D is located well norU1Wcst ofbotl1 U1e shallow and deep recovery well
arrays. Groundwater COC concentrations have generally steadily increased since June 2004.
GROUNDWATER COC ISO CONCENTRATION CONTOUR MAPS
Groundwater chloroform isoconcentration maps for U1e shallow, intermediate, and deep monitoring wells
arc provided as Figures 4 U1rough 6. For each set of monitoring wells two contour maps arc presented.
One map represents groundwater chloroform concentrations under pre-pumping conditions, represented
by May 2005 groundwater analysis data. The second map represents groundwater chloroform
concentrations during May 2008, following startup of U1e GWE system in December 2006.
A comparison of May 2005 and May 2008 groundwater chloroform isoconcentration contour maps.for the
shallow monitoring wells indicates a significant reduction of UIC lateral extent of tl1e overall groundwater
chloroform plume in tl1e shallow saprolite aquifer, and a substantial reduction in U1e lateral extent of U1c
core of the plume (i.e., the area enclosed by 1,000 ug/L isoconcentration contour). By contrast, a
substantial expansion of UIC lateral extent of UIC groundwater chloroform plume in the deeper saprolite
aquifer (represented by the intermediate monitoring wells) appears to have occurred between May 2005

and May 2008. Insufficient groundwater monitoring data for deep monitoring wells is available for U1c
May 2008 groundwater sampling event to confidently evaluate changes in tl1e pattern of groundwater
chloroform concentrations in the bedrock aquifer.
CONCLUSIONS AND RECOMMENDATIONS
Based on U1c results of May 2008 site groundwater sampling/analysis, and in consideration of U1e
observations discussed above, the following conclusions and recommendations are made.
• Pumping of shallow recovery wells appears to be effective in mitigating lateral migration of
groundwater COCs, and in reducing groundwater COC concentrations, in tl1e upper portion of
tl1e saprolite aquifer.
• Pumping of deep recovery wells may be inducing adverse downward migration of groundwater
COCs from tl1e upper portion of U1e saprolite aquifer to the deeper portion of Uie saprolite aquifer
and tl1e bedrock aquifer.
• Collection and analysis of groundwater samples from deep monitoring wells MW-12D, MW-
13 D, MW-16D, and MW-17D is recommended to f urtl1er evaluate potential adverse downward
migration of groundwater COCs into the bedrock aquifer.
• Cessation of pumping of deep recovery wells DRW-A U1rough DRW-B is recommended for at
least a 3-monU1 period to evaluate groundwater drawdown/capture response in the shallow,
intermediate, and deep groundwater monitoring zones under the in0uence of only U1e shallow
recovery wells.
• Quarterly sampling/analysis of groundwater from selected intermediate and deep monitoring
wells may be recommended to more closely track potential further downward groundwater COC
migration from the shallow to deeper aquifer zones.
• Based on the results of above, an upward adjustment of tl1e pump intake depths for the shallow
recovery wells may be recommended to focus recovery and treatment toward the upper saprolitc
aquifer. In addition, adjusuncnts in U1e deep recovery well pump intakes may be recommended
to further treat deep saprolitc or bedrock groundwater COC concentrations without inducing
downward groundwater COC migration from tl1e upper saprolite aquifer.
