EXECUTIVE SUMMARY
Alcatel Network Systems (Alcatel)Raleigh,North Carolina facility is located at 2912 Wake
Forest Road.The facility has been in operation since 1958 under various ownerships and
conducting various operations,including electroplating and printed circuit board manufacturing.
Historical RCRA permitted operations included the storage of hazardous wastes and the drying
of dewatered wastewater treatment sludge.A wastewater treatment plant operated on site from
1978 to 1991,treating 200,000 to 350,000 gallons per day of aqueous wastes.Currently,the
facility's function is limited to research/development and administration.
During the operational history of the facility,releases of specific volatile organic compounds
(VOCs)and metals occurred.A previously conducted RCRA Facility Assessment (RFA)
identified several solid waste management units (SWMUs)and two areas of concern (AOCs).
As of this writing,all previously identified SWMUs have been closed and several voluntary
cleanup operations have been completed in AOC #1 (Drainage system alleyway).Although both
AOCs are addressed in this report,most effort has been directed towards satisfYing data
deficiencies associated with AOC #2 (former printed circuit board manufacturing area).
AOC #1 is located in an alleyway on the north side of the main building while AOC #2 is
located within the footprint of the main building.A RCRA Facility Investigation Workplan (RFI
Workplan)was submitted to the North Carolina Department ofEnvironment,Health,and Natural
Resources (NCDEHNR)in October 1994 and subsequently approved by letter dated July 14,
1995.This document detailed a plan for completing previously initiated assessment ofsuspected
soil and ground water contamination at the facility.
During pre-acquisition auditing on the neighboring Keebler property,regulated constituents were
discovered in the ground water.In response to this finding and in a cooperative effort with the
adjacent landowner,Alcatel initiated voluntary ground water assessment activities prior to the
approval of the RFI Workplan by NCDEHNR.These voluntary actions were conducted in
•
•
accordance with the established RFI Workplan and its addendums.During the assessment,
Alcatel installed an additional 12 ground water monitoring wells on the Alcatel facility and on
the Keebler property (adjacent to the south).
The ground water investigation resulted in the delineation of a VOC constituent plume spanning
three distinct hydrolithologic units.The VOC plume within the saprolite occupies approximately
9.75 acres and within the weathered and competent bedrock comprises approximately 10.50 acres.
Evaluation of core and drilling data indicates that the vertical extent of the aquifer,and VOC
plume,is less than 100 feet below grade.In one boring,no water was discovered between a
depth 80 and 150 feet.The most transmissive hydrolithologic unit is the partially weathered rock
zone spanning approximately 15 feet between the saprolite and competent bedrock.
A soil investigation was conducted beneath the floor of Alcatel's main building to determine if
a continuing source of regulated constituents was present.Sampling concentrated in areas near
the current and former outside building walls and former plating trenches.Other than trace
amounts,no VOCs were detected in AOC #2 soil samples and low concentrations ofcopper and
lead were detected in selected soil samples.Evaluation of metals sampling data indicates low
concentrations of copper and lead occur within the halo of previously remediated areas of AOC
#1.Further remedial excavation of soil contamination is not anticipated.
As a result of the off-site migration ofthe VOC plume,interim corrective measures (ICM)will
be pursued to mitigate further down gradient movement of the plume.This effort will initially
ensue on a voluntary basis.

1.0 INTRODUCTION
1.1 Facility Description
The Alcatel Network Systems (Alcatel)facility is located at 2912 Wake Forest Road in
Raleigh,Wake County,North Carolina.The facility is located in an industrial park
setting near the intersection of Wake Forest Road and the Raleigh Belt-Line (1-440).The
facility is situated on a 24-acre site which consists ofa 234,000 ft2 main building,storage
and maintenance buildings,security buildings,parking lots,and landscaped "natural"
areas.Within the main building,research and development,sales and marketing,
purchasing and accounting,information systems,administration,and a cafeteria occupy
the majority of the space.A Topographic Location Map ofthe facility and the Alcatel
and Keebler Site Map are included in the Appendix (see Figures).
The Kellogg Corporation,a division of ITT,began operation ofthe facility in 1958.At
that time,electronic and telecommunications equipment were produced.At a later date
the name of the facility was changed to ITT;however,it continued manufacturing
electronic and telecommunications equipment.In 1987,Alcatel Network Systems
Corporation purchased the property.Electroplating operations were conducted at the
facility as part of the process for manufacturing printed circuit boards.In 1990,as a
result ofcorporate re-structuring,the name was changed to Alcatel NA Network Systems
Corporation and changed again to Alcatel Network Systems,Inc.,its current name.
During its history,several additions have been made to the main building,as shown on
the drawing titled Building Additions Diagram (see Figures).
During the latter years,when the facility conducted manufacturing processes,a wastewater
pretreatment plant (WWTP)was in operation at the site.Beginning in 1978,the WWTP
treated 200,000 to 350,000 GPD of aqueous wastes from:printed circuit board

•
manufacturing,non-contact cooling/heating water,air compressor condensate,and cooling
tower water.Treated effluent generated by the WWTP was discharged to the City of
Raleigh's publicly owned treatment works (POTW).Dewatered metal hydroxide sludges
from the WWTP were stored in roll-off containers used solely for that purpose.
As a variety of chemicals were utilized in the manufacturing process,Alcatel obtained a
RCRA permit to store the following hazardous wastes at the site:FOOl,F002,FOOS,
F006, F008,DOOI,D002,and D008.As authorized by the permit,these wastes were kept
in 55 gallon containers which were stored on two uncovered pads at the site.The permit
also authorized the drying of dewatered wastewater treatment sludge by evaporation
during storage in a roll-off container located on the former sludge treatment container
storage pad.In addition to roll-off containers and drums,in-ground holding tanks
received aqueous tin,lead,copper,chromium,nickel,mineral acids,caustics,and
ammonium bifluoride wastes from the printed circuit board manufacturing processes.
Those wastes were then treated through the wastewater treatment plant,along with the
rinse waters from the printed circuit board manufacturing process.
The printed circuit board manufacturing operations at Alcatel ceased in 1990.At that
time,all circuit board manufacturing equipment was decontaminated and sold.Currently,
the operation of the facility is limited to research/development and administration.
Structures associated with the manufacturing process,such as holding tanks and plating
trenches,were decontaminated and decommissioned following the shut-down of
manufacturing operations.The WWTP was also closed and decontaminated in 1991.The
former WWTP equalization basin was converted into a chilled water storage tank unit
which is currently used as part of the facility HVAC system.The remaining WWTP

equipment was dismantled,the area was decontaminated,and a level concrete floor was
poured over the existing floor.The area was converted for use as a maintenance area.
1.2 Description of Areas of Concern
Two AGCs,designated AGC #1 and AGC #2,are listed in the RCRA permit for the
Alcatel facility.AGC #1 is located in an alleyway on the north side ofthe main building.
AGC #2 is the former printed circuit board manufacturing area,located within the main
building.Characteristics of each AGC are provided below.
1.2.1 AOC #1
Prior to the termination of circuit board manufacturing operations,a concrete
drainage system was constructed in the alleyway behind the main building.This
system was designed for the collection and treatment of stormwater runoff.
During construction of the new system,soil impacted by volatile organic
compounds and metals was discovered beneath the old asphalt.The investigation
which ensued identified distinct soil impact areas that are now referred to as AGC
#1.
AGC #1 is located in the alleyway on the north side of the main building,as
shown on the drawing titled Location ofImpacted Areas (see Figures).Previous
uses ofthis area have included waste and chemical storage;the area has also been
the location of holding tanks for process materials.A WWTP was formerly
located on the eastern end of the alleyway.The storage areas for wastes and
process materials,as well as the wwrP,have been decontaminated and closed
since decommissioning of the former manufacturing process.Previous
environmental investigations in this area identified four areas (Area 1,Area 2,
•Alcatel Network Systems RFI
NeD 003 185238
February 1996
Page 4
•
•
Area 3,and Area 4)which have exhibited soil contamination.Previous studies
also included the installation of two ground water monitoring wells in the
alleyway.
Area I was an area approximately 15'by 14'(see the drawing titled RFIArea 1,
in Figures)located along the main building,approximately mid-way in the
drainage alleyway.Area 2 was an area approximately 40'by 20',as shown on
the Westinghouse Environmental and Geotechnical Services,Inc.(WEGS)diagram
titled Area No.2 (see Figures),located along the former process sump,on the
east end of the alleyway.Within these areas,soil contaminated by copper and
lead was identified and excavated.The contamination has been attributed to leaks
in subsurface process lines located in the areas.Approximately 277 tons of soil
have been excavated from the two areas as part ofa voluntary remediation effort.
The excavated soil was shipped to GSX in Pinewood,SC,for disposal.
Area 3 was located on the western end of the alleyway and covers an area of
approximately 30'by 10'as shown on the drawing titled RFI Area 3 (see
Figures).Soil sampling from this area indicated the presence of volatile organic
compounds (VOCs).Specifically,the chlorinated compounds:1,I,I
Trichloroethane (TCA),I,1,2 Trichloroethane (2-TCA),1,1 Dichloroethane
(DCA),1,2 Dichloroethane (2-DCA),1,1 Dichloroethene (DCE),and
Tetrachloroethene (PCE)were detected in varying concentrations.Approximately
92 tons of soil were excavated from this area during remedial efforts.The
excavated soil was shipped to GSX in Pinewood,SC for disposal.

•
Area 4 was located in the central portion of the alleyway and measures
approximately 30'by 25',as shown on the WEGS diagram titled Area No.4 (see
Figures).This area was the former location ofa chemical processing shed.Soil
and asphalt samples collected in this area contained extractable lead at
concentrations below regulatory limits.To date,no soil and/or asphalt have been
excavated from this area.
Additional assessment work was conducted in the vicinity of the facility's former
wastewater treatment plant,located at the extreme eastern end ofAOe #1.During
decommissioning of the treatment plant and prior to converting the plant's
equalization basin to its current use a chilled water holding tank,monitoring wells
MW-6 through MW-9 were installed to determine if a release had occurred from
the treatment plant basin.Examination of basin and monitoring well chemical
data has indicated that no impact has occurred.
Remedial efforts have been successful in the removal of contaminated soil from
Aoe #1.Confirmatory samples collected following excavation activities in Area
1,Area 2,and Area 3 verified the effectiveness of the remedial effort.As no
process,chemical,or waste storage areas remain active within Areas 1-4 and in
consideration of analytical results from previous investigations,no additional
investigative activities were designated for AOC #I during this investigation.
Results of previous investigations are appended to this report and will be
referenced in Section 4.0.

AOC #2 is the former printed circuit board manufacturing area,located within and
beneath the main building.During previous manufacturing operations,
electroplating and chemical plating processes were conducted in this area.The
process incorporated coated,concrete,in-ground trenches which acted as conduit
for rinse water and as secondary containment for process piping.These trenches
were located in the floor of the building,within the area designated Former
Printed Circuit Board Area as shown on the drawing of the same title (see
Figures).TCA was used in this area for the cleaning of printed circuit boards.
A distillation unit (still),used to purify TCA,was also located in this area.
All process areas (troughs,distillation equipment,etc.)and/or chemical/waste
storage areas which formerly operated in this area have been decontaminated and
decommissioned.The former process trenches were thoroughly decontaminated
and the concrete was examined for evidence of corrosion and/or deterioration.
Deteriorated concrete was removed and wipe tests were performed to determine
if process chemicals had penetrated into the concrete.The results of these tests
were negative,and the trenches were filled with concrete.The area is now used
for office and laboratory space,and as a print shop.
Previous environmental investigations around the facility and beneath the floor of
the former manufacturing area have identified VOCs in the soil and at the water
table.Specifically,the compounds TCA,2-TCA,DCA,2-DCA,DCE,PCE,
Trichloroethene (TCE),Trichlorofluoromethane (TCFM),Benzeneand Chloroform
have been detected in ground water samples.These compounds were not present
in soil samples with the exception of one sampling location where 1,I DCE was

•
detected near the water table.Copper was detected in both soil and ground water
samples;however,concentrations were generally at or near assumed background
levels.The drawing titled Laboratory Analytical Results (Sept.1993)(see
Figures)gives the concentrations of compounds detected during previous
investigations.
Benzene has only been detected in one sample during one sampling event at a
concentration of 2.5 ug/L.Due to this frequency,the low concentration,and the
lack of an apparent source,benzene is thought to be a laboratory artifact,and not
clearly present in ground water beneath the Alcatel facility.To date,no soil or
ground water remedial actions have been conducted within AOC #2.

2.0 ENVIRONMENTAL SETTING
2.1 Regional Geology and Hydrogeology
Wake County is located within the northeastern portion of the Piedmont physiographic
province of North Carolina.The regional terrain is generally rolling,with elevations
ranging between 200 and 500 feet above mean sea level (MSL)within the county.The
topography is dissected by dendritic streams which allow for relatively good drainage.
The Piedmont physiographic provmce IS comprised of several somewhat parallel
metamorphic "belts."The metamorphic belts are areas ofregionally metamorphosed rocks
which have been delineated and characterized based on their metamorphic grade.Wake
County resides within a high grade metamorphic zone known as the Raleigh Metamorphic
Belt,or the Raleigh Terrane.The region is bounded on the west by rocks of the Carolina
Slate Belt,and on the east by rocks of the eastern Slate Belt.The Raleigh Terrane is
comprised primarily of medium to high grade,mica schists and felsic gneisses.Local
granitoid intrusions are also common in the region (Stoddard,et.a!.,in Wright and Zullo,
1991).
The Piedmont is characterized by a soil veneer derived from weathered bedrock,or
saprolite,which overlies competent bedrock.The thickness of the saprolitic soil varies
considerably between locations,but is generally thicker in areas where topographic slope
is low,and infiltration from precipitation is abundant.Competent bedrock occurs at
varying depths below the saprolite,and is typically fractured by jointing and/or faulting.
Joints are most prevalent at shallow depths where overburden pressures are minimal,
whereas faults extend to considerable depths.
•Alcatel Network Systems RFI
NeD 003185238

Page 9
•••••••'':
The pnmary mode of ground water storage within the saprolite is between the
intergranular pore spaces,while storage within the bedrock occurs largely within the
fracture system.Ground water recharge to the saprolite and bedrock is generally
accomplished by infiltration from precipitation,with surplus conditions beginning in the
Autumn and continuing through Winter.Discharge of stored water occurs primarily as
baseflow into surface water bodies.Movement ofstored ground water varies considerably
with rock type and the degree ofweathering.Common hydraulic conductivity values for
saprolite range from less than one to several feet per day;values for fractured rock vary
greatly.
2.2 Site Geology and Hydrogeology
The soil and unconsolidated materials beneath the facility have been documented as being
a residuum of a granitic protolith,with thicknesses varying from approximately 3.5 to
greater than 20 feet.Typically,the soils are soft to very dense,white to red-brown,
clayey to silty,very fine sands.They are typified as containing abundant mica particles,
prevalent white quartz and feldspar rich zones,local abundance of coarse fragments,and
dark brown mottles.Generally,the soils are classified as ML and 8M under the Unified
Soil Classification system.
Three hydrolithologic zones have been identified at the site.The first zone is a highly
weathered saprolite material consisting ofsilt,sand,and clay sized particles.The second
zone discontinuously underlies the first zone,and is comprised of partially weathered
bedrock (PWR).The third unit is bedrock,consisting ofa fractured metamorphic bedrock
comprised of zones of granite,pegmatoidal granite,and gneiss.

•
Thirty-three ground water monitoring wells have been installed at the site.Seventeen
wells are located on the Alcatel property,and 16 are located on the Keebler property
immediately south of the Alcatel facility.Static ground water level measurements have
been taken in each well at various times in order to determine head distributions and the
direction of ground water flow.Consistently,the direction of ground water flow within
the saturated wne has been toward the west-southwest,along a relatively uniform
gradient.
Ground water flow in the bedrock unit is generally to the southwest,with an apparent
"trough"in the potentiometric surface beneath the main building.Vertical ground water
flow is typical of a recharging area,with an upward gradient existing local to the stream
which transects the western portion of the study area.
2.3 Topography and Surface Water Hydrology
The area immediately surrounding the Alcatel facility is characterized by moderate to
steep slopes.To the north,east,and south of the facility,the natural grade slopes
moderately toward the south and southwest.To the west of the facility (across Wake
Forest Road),the natural grade steepens and slopes toward the east.The topography of
the site and surrounding properties has been extensively modified by construction and
landscaping activities.Area and facility topography are shown on the drawings titled
Area Topography and Facility Topography (see Figures).
An unnamed gaining perennial stream traverses the western portion of the facility.The
stream begins approximately 4,000 feet up-gradient of the facility and discharges
approximately 2,500 feet down-gradient into Crabtree Creek.The baseflow of the
unnamed stream is attributed to shallow ground water discharge.Discharge from storm
•,'',I

•
sewers and runoff from parking areas,as well as natural overland flow during
precipitation events,also contribute water to the stream.The direction of water flow in
the unnamed stream is towards the south.At its confluence with Crabtree Creek,the
direction of stream flow changes to the southeast.The unnamed stream and Crabtree
Creek are the only two ground water receptors in close proximity to the study area.
Several surface water features are located in the region.These features include streams,
ponds,stormwater detention basins,lakes,and rivers.The City of Raleigh (which
includes the Alcatel facility)relies on surface water for the potable public water supply.
Falls Lake Reservoir,located approximately 16 miles north of the site,is the source for
the public water supply.Additionally,no water supply wells are reported within a two
mile radius of the site.
2.4 Climate
The Raleigh area is characterized by a humid,subtropical climate with mild Winter and
warm Summer seasons.Typically,July is the warmest month and January is the coldest
month,with mean monthly temperatures of 77.70 F and 39.60 F,respectively.The annual
mean humidity is 70%,with humidity values typically being higher in the Summer and
Fall months.
Average monthly precipitation varies by season.Historically,the month with the greatest
precipitation is August with an average 4.44 inches,while the month with the least
precipitation is October with an average 2.73 inches.The normal mean annual
precipitation is 41.76,and the 10-year,24-hour storm event for this area produces
approximately 5.50 inches ofrainfall.Snowfall has been documented to occur between
the months of November through April,with a mean annual snowfall of 7.20 inches.

3.0 METHODS OF INVESTIGATION
Page 12
•
This section describes RFI methodology employed for areas deficient or void of pre-existing
assessment data.The information obtained from these methods is intended to augment results
of previous voluntary assessment actions performed at the site.Further reference to previous
investigative work is addressed in Section 4.0.
3.1 Soil Investigation
During the months of May and June 1995,a soil investigation was conducted beneath
AIcateI's main building.Ten soil borings were advanced beneath the floor of the main
building to depths of approximately II feet below grade,or to auger refusal,whichever
was encountered first.Soil borings were concentrated in two areas:in the area along the
exterior wall of the original 1958 building (vicinity of SBR-l),and in the vicinity of
former plating trenches (SBR-7 and 9).Please reference the Soil Sampling Locations
drawing (see Figures).
The sample collection procedure was similar for each boring.First,an electric rotary
hammer or jackhammer was used to cut a small hole in the concrete floor.A clean,
stainless steel hand auger was then used to advance the boring and to facilitate sample
collection.Borings were identified by the convention "SBR-I,2,3 ..."with the sample
identification suffixes "A","B",and "C"corresponding to the following depths below
grade:
Ibl=A,;",)=1-=2=ft==B,,;,)=4-=5=fi=t=C,.;)=9=-1=0=o=r=10=-=1l=f=t===="11
Samples obtained from the boring for monitoring well MW-13s were identified with
suffixes "A"and "B"corresponding to the following depths below grade:

•
Upon retrieval,the samples were split into two aliquots.The first aliquot was placed in
labelled,laboratory supplied containers,and maintained on ice pending selection for
possible laboratory analysis.The second aliquot was placed into clean,plastic,zip-lock
bags,evacuated of air and maintained on ice pending field analysis.In accordance with
the RFI Workplan,all soil samples were field analyzed for pH and the presence of organic
vapors. Soil pH was determined using SW-846 Method 9045.To screen for the presence
of organic vapors,a measure of soil was placed in a clean,plastic zip-lock bag and
allowed to volatilize in direct sunlight or a heated area for approximately ten minutes.
An organic vapor analyzer (OVA)was then used to screen the headspace in the sample
bags for organic vapors.All field analytical results are summarized in Table 1 included
in the Appendix (see Tables).
The following samples were selected for laboratory analysis:MW-13sA,MW-l3sB,
SBR-lA,SBR-lC,SBR-2A, SBR-3A,SBR-3C,SBR-4A,SBR-4C, SBR-5, SBR-6,SBR-
7,SBR-8A,SBR-8B,SBR-9A,and SBR-9C.Auger refusal was encountered at depths
of approximately five feet below grade in borings SBR·5,6,and 7.As a result,
laboratory soil samples were composited using soil collected from the "A"and "B"depth
intervals in these borings.
Samples selected for laboratory analysis were placed in labelled,laboratory supplied
containers,maintained on ice,and delivered to Paradigm Analytical Laboratories,Inc.
(PAL)in Wilmington,NC.The samples were analyzed for volatiles by 8W-846 Method
8260,and copper and lead by Method 6010.Laboratory analytical results are summarized
in Table 2 (see Tables).Complete analytical reports,including Chain ofCustody records,

The hand auger was decontaminated following the procedures outlined in the RFI
Workplan.All soil cuttings were containerized in 55 gallon drums and temporarily stored
on site.Following completion ofthe borings,the boreholes were backfilled with mixture
of Portland cement and bentonite,with the exception of one borehole which was
converted to a monitoring well (MW-13s).Following the insertion of well construction
materials,the top 12 inches were repaired with a concrete mixture of Portland cement and
clean filter sand.
3.2 Monitoring Well Installation
Prior to this investigation,twelve monitoring wells (MW-Is through MW-12s)existed on
the Alcatel property and none on the adjacent Keebler property.Coincidental to this
investigation,eleven monitoring wells were installed on the Keebler property by Aquaterra
during pre-acquisition auditing activities.The discovery of VOCs in Keebler's ground
water prompted the submittal of an addendum to Alcatel's RFI Workplan,resulting in
the installation of four monitoring wells (all on the Keebler property)in addition to the
seven originally planned.All previous and new well installation activities ultimately
resulted a total of 33 monitoring wells installed on the combined properties,18 of which
are associated with the Alcatel property and 15 with the Keebler property.
Two recovery wells were installed during the RFI activities,RW-l and RW-2.RW-l was
originally intended to be constructed as a deep monitoring well;however,due to high
water yielding conditions in the partially weathered rock and the risks associated with
grouting surface casing in this zone,this well was completed as a six-inch J.D.recovery
well.Recovery well RW-2 was installed for aquifer pump testing.

Wells within the study area are identified by well function,number,depth,and property
location codes (e.g.MW-2s,MW-12dk).The following convention has been used:
Well Function:"MW"denotes Monitoring Well
"RW"denotes Recovery Well
Well Number:
Well Depth:
Location:

"s"-shallow well screen usually set in unconsolidated material
"i"-intermediate well screen set in PWR or upper fractured rock
"d"-deep weIl screen set in fractured rock
"k"denotes Keebler property;the lack ofa property code indicates
the well is on Alcatel property.
The three Type II (shallow)monitoring wells were installed near the water table within
the unconsolidated materials (saprolite).MW-13s was installed inside AlcateI's main
building using a stainless steel hand auger.MW-8sk and MW~9sk were installed with a

power drilling rig using hollow-stem augers.Soil samples were collected during drilling
operations in order to classify the soils which were encountered.Split-spoon samplers
were used to collect samples during power drilling rig operations,while grab samples of
cuttings were obtained from the hand augered borehole.All shallow wells were
constructed of two-inch,Schedule 40 PVC manufactured screen and casing.The wells
were completed with locking caps,and flush-mount bolt-down covers.
Borings for the two Type II recovery wells (RW-l and RW-2)were advanced using air
percussion drilling techniques (air hammer)and were screened in the saprolite and
weatheredlhighly fractured rock zones.Fluid returns generated during drilling indicated
the transition between saprolite and hard rock was highly productive,with instantaneous
yields of RW-l reaching 100 gallons per minute (OPM).These wells were constructed
ofsix-inch,Schedule 40 PVC manufactured screen and casing.The wells were completed
with locking caps,and flush-mount bolt-down covers.
Each ofthe seven Type III monitoring wells were installed within the competent bedroCk.
The initial boreholes for these wells were advanced using an air hammer to depths
approximately two feet below the top of competent bedrock.A six-inch Schedule 40
PVC surface casing was then set and grouted into place.An exception to this was well
MW-12dk,in which a six-inch carbon steel surface casing was used due to heaving
unconsolidated material just above the bedrock surface.Surface casing grout was allowed
to cure for 12 to 24 hours.A S.2S-inch air hammer was then used to advance a borehole
into the fractured bedrOCk.Well screens spanned 10-30 feet to assure intersection with
water bearing fractures.The wells were constructed of two-inch Schedule 40 PVC

manufactured screen and casing.Each well was completed with a locking cap and flush-
mount bolt-down cover.
Yields in the fractured rock were noted to drop off significantly at depths greater than 40
feet below grade.Yields on the order of one to five GPM were typical during drilling
operations where water bearing fractures were intersected.
All cuttings and fluids generated during drilling operations were containerized and
temporarily stored on site.Containment basins Were constructed in the decontamination
area and around the boreholes for the air hammered wells.Decontamination water,as
well as fluids generated during drilling,were captured within these basins and
subsequently containerized.At the completion of drilling activities,the containment
basins were dismantled,and all material (plastic,etc.)which had come into contact with
potentially contaminated media were containerized.
All newly installed wells were developed by purging the wells of five well volumes or
until turbidity stabilized.For the shallow wells,dedicated disposable bailers were used
to develop the wells.Intennediate and deep wells were developed with a Brainard-
Kilman (B-K)hand pump.The hand pump was decontaminated between wells by
thoroughly washing the unit with Alconox soap,steam pressure washing,and a water
rmse.All water generated during the development process was containerized and
temporarily stored on site.Disposal of recovered materials is pending.

3.3 Well Sampling and Analysis
Ground water samples were collected from monitoring wells at the site to characterize
ground water quality within the aquifer system.Samples were collected from the
following monitoring wells:
ALCATELPROPERTY
MW-ls MW-2s MW-2d MW·3s MW-3d MW-4
MW-4d MW-5s MW-7s MW-7d MW-9s MW-l
MW-lls MW-12s MW·13s

MW-5sk MW-6sk MW-6ik MW-7sk MW-7ik MW-8sk
MW-8dk MW-9sk MW-9dk MW-12dk
Prior to sampling,at least three well volumes of water was purged from each well.For
the shallow wells,purging was accomplished by bailing the wells using dedicated,PVC
disposable bailers.For the deep wells,a B-K hand pump was utilized.The hand pump
was thoroughly decontaminated between wells in accordance with the procedure described
previously.All purge water was containerized and temporarily stored on-site.
The wells were allowed to recover overnight prior to sample collection.Dedicated
disposable bailers were used to collect water samples from the wells.Clean,ny Ion line
was attached to the bailers,and the bailers were slowly lowered into the well to a depth
just beneath the surface of the water.The bailer was recovered and the sample was
carefully decanted into the appropriate containers.Laboratory samples were decanted into

•
labelled,laboratory supplied containers and maintained on ice.Samples for field analysis
were decanted into clean glassware and analyzed immediately.The in-field analysis
consisted of measuring sample pH,temperature,and specific conductance,as well as
noting the physical appearance of the sample.In-field analytical results are summarized
in Table 4 (see Tables).
Laboratory samples were shipped via overnight courier to PAL in Wilmington for
analysis.The samples were analyzed for target volatiles (as specified by the Workplan)
by SW~846 Method 8260,and for copper and lead by Method 6010.Table 5 (see
Tables)provides a historical summary of laboratory analytical results for each well.
Complete analytical reports for sampling conducted during this investigation are included
in Appendix A.
3.4 Stream Sampling
Surface water samples were collected from the unnamed stream which transects the
western portion ofthe study area.Prior to sampling,the stream was examined for flow
conditions,evidence of "seeps"along the banks of the stream and suitable locations of
sampling points.Flow velocity measurements were also obtained at this time.Flow
measurements were taken approximately 100 feet down stream of Outfall A as shown on
the Water Table Surface Map (see Figures).Additionally,Outfall A served as the
general location for the up-gradient water quality sample (CS-I)while the down-gradient
sample (CS-2)was collected from Outfall B.
Flow was measured by recording the length oftime required for a float to travel a known
distance over the deepest portion ofthe stream channel (highest velocity).The float was
allowed to travel a distance of 45 feet on five successive runs.Elapsed time and the

resulting velocities are given by the following table.Baseflow discharge was calculated
from velocity information and is further described in Section 4.6.
Run I 1.52 min 29.61 ftlmin
Run 2 1047 min 32.14 ftlmin
Run 3 lAO min 32.14 ftlmin
Run 4 1.47 min 30.61 ftlmin
Run 5 1.28 min 35.16 ftlmin
Water samples were collected up-gradient (CS-I)and down-gradient (CS-2)of the study
area to determine if target constituents were being contributed to the stream during its
flow across the property.Samples were collected at the water/air interface during low-
flow (baseflow)conditions,and within the center ofthe channel.Samples were described
as relatively clear with algae particles.Clean glassware was used to collect water
samples.Upon acquisition,samples were carefully decanted into laboratory supplied
sample containers,maintained on ice,and transported to PAL for laboratory analysis.
Each sample was analyzed for volatiles by SW-846 Method 8260,and copper and lead
by Method 6010.Samples were also field analyzed for temperature,pH,and specific
conductivity.Field parameters are summarized in Table 6 (see Tables).Laboratory
analytical results are summarized in Table 7 (see Tables).Complete laboratory analytical
reports are included in Appendix A.
3.5 AqUifer Testing
Aquifer testing was performed on well RW-2 during the week of January 9,1995.RW-2
was screened from 15 to 40 feet below grade within the site's "high yield"interval.This
•Alcatel Network Systems RFI
NeD 003 185 238
February 1996
Page 21
interval spans approximately 30 feet and is composed of the entire PWR unit,the upper
portion of the fractured rock,and the lower portion of the saprolite.Interpretation of
boring logs,well development and aquifer test data indicates that this interval transmits
most ofthe site's ground water.Although water exists intermittently in deeper fractures,
yields within the fractured rock are significantly less.
A Grundfos Redi-flow 2 submersible pump was installed approximately one foot above
the bottom of the screened interval in the well.Pressure transducers were installed in
RW-2 (the pumping well),MW-2ik and RW-I and were connected to a Hermit 2000C
data logger.Water recovered during the test was routed through a totalizing flowmeter,
two parallel 50 micron particulate filters,and two 55 gallon in-line low-pressure carbon
vessels prior to discharge to the Raleigh POTW.In accordance with the requirements of
the temporary discharge permit issued by the City of Raleigh,influent and effluent
samples were collected at periodic intervals and analyzed using a field gas chromatograph.
These samples monitored breakthrough of three targeted chlorinated compounds (l,I
DCE;1,1,1 TCE;and PCE)between the carbon treatment units.Influent and effluent
analytical results are summarized in Table 8 (see Tables).
Aquifer testing consisted ofa four-hour step-drawdown pumping test,followed by a 72-
hour constant discharge aquifer test.The step-drawdown test was performed to determine
the optimum pumping rate for the 72-hour test.During the step-test,the discharge ofthe
pumping well was increased at various times and the drawdown response of the aquifer
was measured.The step test indicated a discharge on the order of7.5 gpm would produce
a suitable drawdown (about 4 feet)and limit turbulent flow conditions during the 72-hour
pump test.The aquifer was allowed to recover for twelve hours prior to commencement
of the 72-hour pump test.Step test data has been purposely omitted from the Appendix.

The 72-hour pump test commenced at 11:12 am on January 10,1995.In addition to
wells RW-l,RW-2,and MW-2ik which were connected to the data logger,water levels
were also routinely monitored by hand in wells MW-4d and MW-2sk.The test was
concluded at 11:40 am on January 13,1995.A total of 32,140 gallons of water was
discharged during the aquifer testing.Aquifer test field data is included in Appendix C.

4.0 RESULTS OF INVESTIGATION
Page 23
•"\'~',
Findings of the RFI are presented in this section.As stated previously,this RFI is intended to
augment findings of previous assessment and remedial efforts.Several voluntary actions have
occurred at the facility,each of these actions is summarized below.As necessary,complete
reports or pertinent portions theteof are included in the Appendix for clarification.Although
results of this RFI are the focus of this section,previous information has been included where
appropriate for explanation and understanding.
4.1 Summary of Previous Actions -AOC #1
During retrofit and construction ofthe drainage system alleyway,Alcatel discovered areas
exhibiting soil discoloration and unusual odors.An investigation ensued which identified
three locations of impacted soils.A fourth area was later identified during equipment
dismantling activities.AGC #1 is defined by these four soil impact areas.
This section provides a summary of previous investigative and remedial work at the
facility regarding AGC #1.Details of each previous phase are provided in the actual
reports,located in Appendix D.These reports are also on file with NCDEHNR-DSM.
Pursuant to the requirements ofthe RFI Workplan,these reports are incorporated in this
RFI by reference.
4.1.1 AOC #1 Areas 1 and 2
Facility modifications and associated environmental samplingperformed by Alcate1
identified two areas where soil had been discovered with elevated levels of copper
and lead.Voluntary remedial actions were pursued by Alcatel to remedy the
condition.Westinghouse Environmental and Geotechnical Services,Inc.(WEGS)
was contracted to perform the remedial activities.WEGS summarized their
Alcatel Network Systems RFI

•
remedial activities in three reports titled Environmental Cleanup Area No.1,
Environmental Cleanup Area 2,and Environmental Cleanup Area 2 Addendum
(provided in Appendix D).
At both areas,no further remedial action was recommended due to the toxicity
characteristic sampling results.A total of 277 tons of soil have been removed
from Areas I and 2.Location diagrams,sampling results,and waste manifests for
the removed soil are included in the referenced reports.
4.1.2 AOC #1 Area 3
Voluntary remedial action was taken by Alcatel to remove soil impacted by VOCs
at Area 3.A total of 92 tons of impacted soil were removed and properly
disposed as a result of this effort.In late 1990,National Environmental
Technologies,Inc.(NET)was contracted by Alcatel to delineate any remaining
soil containing VOCs in the vicinity of Area 3.
Additional VOC impacted soil was identified as a halo around the Area 3
excavation;however,due to the presence offoundation structures,these soils were
inaccessible to further excavation.Additionally,the potential of leaching VOCs
from the soil is reduced by the presence of concrete over the entire area.
Subsequent remedial work at Area 3 has not been pursued due to the structural
interferences and reduced leaching potential.Location diagrams,sampling results,
and remedial data regarding Area 3 are included in NET's February 1991 report
titled Phase I Soil and Groundwater Impact Assessment (Appendix D).

Additional sampling was perfonned concurrent with the Area 3 investigation to
detennine if VOCs were present at Areas I and 2 following the excavation
activities mentioned above.Sampling results indicated VOCs are essentially
absent from these areas.These sampling results are also included in the Phase I
report referenced above.
4.1.3 AOC #1 Area 4
Area 4 previously contained a shed-like structure housing two chemical reaction
tanks.The structure and tanks were dismantled and removed as part of Alcatel's
tennination of printed circuit board manufacturing operations.As the tanks
processed lead containing solutions,WEGS was contracted to perform lead
sampling at Area 4 following dismantling activities.Their assessment is
summarized in a report titled Field Sampling and Analytical Services·Area No.
4 Soil Sampling (provided in Appendix D).
Analytical results ranged from below quantitation limit (BQL)to 1.3 mg/L in
TCLP extracts and from BQL to 21,100 mg/Kg as total lead in soil.WEGS
indicated that "the lead contamination is limited in the soil to a depth of
approximately one foot and in the overlying paving materials."A sampling
location diagram and sampling results are included in the referenced report.No
remedial action has occurred in Area 4 as of this writing.
4.2 Summary of Previous Actions·AOC #2
The NET report titled Phase I Soil and Groundwater Impact Assessment (Appendix D)
was the first ofthree reports which addressed soil and ground water contamination in the
area now referred to as AOe #2.Objectives of the report included assessment of ground

water quality and characterization ofthe hydrogeological conditions at the site.Pursuant
to these objectives a passive soil gas survey was conducted,five monitoring "wells were
installed and falling head aquifer tests were performed.
Due to the soil gas survey being conducted beneath the floor slab of the main building,
results were less than conclusive;however,results did indicate that potential ground water
impacts may be relatively widespread.Subsequent installation offive shallow monitoring
wells (MW-1 s through MW-5s)confirmed this suspicion by the identification of certain
VOCs in ground water samples recovered from the wells.
The aquifer characterization study revealed uniform weathering to the PWR/hard rock
interface,a consistency in hydraulic conductivity between the three wells tested,and a
consistent hydraulic gradient between the well locations.Hydraulic conductivities ranged
from 3.02 to 5.72 ft.lday with gradients ranging from 0.16 to 0.19 ft.lft.Further chemical
and physical data regarding this study can be found in the referenced report.
Additional ground water quality work was accomplished during closure of Alcatel's on-
site waste water treatment plant.This work was performed independently of the above
mentioned assessment activities and resulted in the installation of four additional ground
water monitoring wells.Monitoring wells MW-6s through MW-9s were installed up"and
down-gradient of the treatment building.Sampling results from these wells indicated no
impact to ground water occurred as a result of the operation of the treatment plant.
Further voluntary ground water investigative work was initiated in June 1993 and
continued into October of the same year.This work is represented by two NET reports
dated August 11,1993 and October 22,1993 and titled Results of Ground Water

Investigation and Report ofGround Water Investigation,respectively (see Appendix D).
During these investigations,several borings were advanced inside the Alcatel main
building for the purpose of water quality and soil assessment.Results indicated that little,
if any,soil contamination was present;however,VOC impacted ground water
encompassed an area of approximately four acres in the vicinity of the main building.
The installation of monitoring wells MW-lOs through MW-12s was accomplished during
the studies.
4.3 S&ME Soil Sampling on Keebler Property
During environmental auditing activities associated with future development of the
Keebler property,Soil &Materials Engineers (S&ME),under subcontract by others,
sampled soils on the Keebler property to establish baseline conditions.Their assessment
was conducted during the period February through April 1995.
During their study,S&ME collected soil samples from II points on the Keebler property.
Four of these points were located on the northeast portion of the property,outside the
present Structures.Seven points were located inside the Keebler building,in the vicinity
ofmonitoring wells MW-7sk and MW-7ik.Locations ofthe sampling points are depicted
on the Soil Boring Locations drawing (see S&ME Soil Sampling,AppendiX D).
The soil borings were advanced with a stainless steel hand auger.All soil samples were
screened for the presence of organic vapors using a Toxic Vapor Analyzer (TVA)and an
OVA.Depths of the soil borings ranged from 4.3 feet to 7.3 feet below grade.Soils
were described as clayey to silty sands and sandy silts to fine sands.Rock fragments
and/or partially weather rock (PWR)were encountered in six ofthe borings.Soil samples
for laboratory analysis were selected from grab samples obtained during boring

advancement.These samples were submitted to PAL in Wilmington,NC for laboratory
analysis of Volatile Organics by EPA Method 601.No volatile compounds were detected
during analysis ofthe soil samples.Complete laboratory analytical data for these samples
are included in Appendix D (see S&ME Soil Sampling).
4.4 RFI Soil Investigation
Soil sampling activities concentrated on areas beneath the main building which may be
acting as a source for the ground water pathway.Investigative activities were
concentrated in three areas:I)Near the north (outside)wall of the main building;2)
Near the location of the east (rear)wall of the original 1958 building;and,3)Near the
former plating trenches.Soil samples collected from beneath the floor of the main
building did not indicate impact by volatile constituents,however,several samples showed
elevated concentrations of copper and/or lead.The majority of samples exhibiting
elevated metals concentrations were collected near the north wall ofthe building bordering
AOC #1.Soil sampling locations are shown on the drawing titled Soil Sampling
Locations (see Fignres).AOC #1 and AOC #2 are shown by drawings titled Location
of Impacted Areas and Former Printed Circuit Board Manufacturing Area (see
Figures),respectively.
As the identification of potential sources of contamination was an important objective of
the soil investigation,soil samples collected from beneath the main building were
analyzed for total metals.This analysis quantifies concentrations of metals in the soil,
either free or bound within mineral or chemical structures,but gives no indication as to
the mobility (i.e.,leachability)of the constituent.Initial examination of analytical data
for total copper suggested that a correlation exists between sample location and total
copper concentration.Because of this,analytical data was statistically examined to
•Alcatel Network Systems RFI
NCD 003185238
February 1996
Page 29
•
confirm such a correlation,and to identify samples having a concentration that may be
naturally occurring.
In consideration ofprevious sampling results in Areas I through 4 and realizing the close
proximity of AGe #1 to AGe #2,it was necessary to statistically compare AGe #1 and
AGe #2 for the purpose of source identification.As many samples were acquired near
the wall between AGe #1 and AGe #2,a frequency analysis was performed to determine
if a correlation exists between sample location and total copper concentration.For the
frequency analysis,a two by two matrix was established.The options for the matrix are
shown below:
Near Outside Wall Near Outside Wall
Low Copper Concentration High Copper Concentration
I II
Away from Outside Wall Away from Outside Wall
Low Copper Concentration High Copper Concentration
III IV
where:
Near the Outside Wall is defined as a sampling location which is inside the main building at a distance
less than or equal to 10 feet from the outside wall;
Awayfrom the Outside Wall is defined as a sampling location which is inside the main building at a
distance greater than IO feet from the outside wall;
Low Copper Concentration is defined as samples having a total copper concentration of iess than or
equal to 10 mglkg;
High Copper Concentratian is defined as samples having a total copper concentration equal to or
greater than 10 mglkg.
•Alcatel Network Systems RFI
NCD 003 185 238
February 1996
Page 30
Analytical results for 21 soil samples were used during the frequency analysis.Sixteen
of the samples were obtained during this RFI (results in Appendix A)and five were
obtained during NET's October 1993 investigation (see report titled Report of Ground
Water Investigation,October 22,1993 in Appendix D).The frequency analysis resulted
in the following distribution:
Near Outside Wall Near Outside Wall
Low Copper Concentration High Copper Concentration
(0)(9)
Away from Outside Wall Away from Outside Wall
Low Copper Concentration High Copper Concentration
(11)(1)
The correlation ofhigh total copper concentrations in close proximity to the north outside
wall (Quadrant II)implies that the source for copper detected in soil beneath the main
building is located near the AOC #I1AOC #2 boundary or completely within AOC #1.
With the exception of sample SBR-7 (near the former plating trench),it appears that
releases within AOC #I are the likely source for copper detected in AOC #2 soils.The
highest copper concentration was detected in sample SBR-8B at 74 mglkg.Conversely,
concentrations detected away from the AOC #I1AOC #2 boundary (Quadrant III)may
closer approximate naturally occurring concentrations.The geometric mean concentration
of total copper for these II samples is 1.45 mg/kg.
•Alcatel Network Systems RFI
NCD 003185238
February 1996

•
Soil samples were also analyzed for total lead.Analysis of this data does not result in a
similar correlation as compared with the data for total copper.Concentrations of total
lead varied from BQL (below quantitation limit)to 10.7 mglkg.As no correlation
between location and concentration was noted during evaluation ofthe data,it is difficult
to determine a likely background concentration or remaining source area,if any,for the
constituent.
Copper and lead remaining in AOC #1 and AOC #2 soils are not accessible via air
inhalation,water ingestion or soil ingestion pathways.All soils identified as having
concentrations of copper or lead are contained beneath concrete structures.This
arrangement virtually eliminates leaching to ground water and prohibits direct contact by,
humans,eliminating the soil ingestion pathway.Exposure via the air ingestion pathway
is essentially non~existent as chemical complexing or volatilization processes would be
required to liberate the constituents.
Although care should be exercised when using published risk-based concentrations for
setting constituent no-action levels,it is important to note the difference between
concentrations detected in site soils and published risk-based data.For example,the
October,1995 EPA Region III risk-based concentration table lists a copper concentration
of 82,000 mglkg for the industrial soil ingestion pathway,well over 1000 times the
highest concentration discovered at the Alcatel facility.Risk-based lead data was not
included in the EPA report.
4.5 Hydrogeological Investigation
A total of thirty~threeground water monitoring wells have been installed at the site for
the purpose of determining ground water quality and water levels within the three
•Aleatel Network Systems RFI
NCD 003 185 238

Page 32
•
hydrolithologic units of the study area.Geologic logging during the installation of these
wells has provided key infonnation regarding the lateral and vertical hydrogeological
relationships between these units.Although some water level variation exists between the
saprolite and deeper fractured rock,the entire system is interconnected and functions as
a single aquifer.Interpretation of rock core and drilling infonnation place the bottom of
the aquifer at a depth of approximately 100 feet below grade.
4.5.1 Profile of the Aquifer System
Boring logs and well construction data (Appendb:B)were used to generate
hydrogeologic cross-sections for the study area (see Figures).The orientation of
each of the three sections is shown on the Cross-Section Location Map (see
Figures).Although more detail is provided on the boring logs,variations within
the subsurface are depicted as three distinct hydrolithologic units on the sections.
These units are:the unconsolidated materials (saprolite),PWR,and hard rock
(bedrock).
Observations during drilling and well installation activities indicate that the water
bearing zone having the highest yield is the PWR and upper twenty feet of the
fractured rock.This zone is composed ofa mixture of unconsolidated materials,
weathered rock and fractured bedrock and represents the transition from saprolite
to hard rock.The thickness and degree of weathering of the high yield zone
varies somewhat across the site.The lateral thickness change of the PWR,as
depicted on the cross-sections,is a good indication of this variability.
Above the high yield zone is the saprolite,composed ofunconsolidated sands,silts
and clays.This material is derived from the chemical and physical weathering of
•Alcatel Network Systems RFI
NCD 003 185 238

•
the bedrock.The degree of weathering of the saprolite is largely unifonn
throughout the site.Relic structures and remnant foliations were present at all
locations where split-spoon samples were obtained.
Below the high yield zone is hard fractured rock composed of granite and gneiss.
A rock core was obtained from the boring for MW-4d at Alcatel for the purpose
of characterizing the fractured rock.Within the 37.5-foot core interval (from 30
to 67.5 feet below grade),seven sub-equally spaced fractures were noted.The
width ofthese fractures varied from slightly less than one millimeter in the upper
portion of the core to ''paper''thickness with depth.Most fractures were within
felsic and pegmatoidal felsic zones,and were relatively "clean"with little iron or
magnesium precipitates present.The fractures within mafic zones appeared to be
at least partially filled with a dark-colored,clay-like material,which can be
attributed to the hydrous weathering of biotite.Recovery of the core was 100
percent.
Observations during drilling activities indicate that the fractures pinch out with
depth.Aquaterra attempted to install a deep monitoring well at the MW-2k nest.
This well is identified as MW-2dk on the boring logs (Appendix B).The log
indicates that competent bedrock was encountered at 28.5 feet and continued
through a depth of 150 feet below grade.Fractures dissipated with increasing
depth and no water was encountered from 80 to 150 feet.The well was not
completed due to dry conditions and the loss of drilling tools in the borehole.

4.5.2 Fracture Trace Study
Due to the general lack ofoutcrop at the study area,fracture trace information was
obtained from researchers familiar with the area geology.Extensive geological
mapping in the Raleigh West quadrangle (which begins less than 1/4 mile west of
the Alcatel site)during the period 1992-1994 resulted in the identification ofmajor
lineations in the area.Dr.D.E.Blake,of UNC-W,identified a strong foliation
trending roughly N 20 E throughout the mapped portion of Raleigh West
quadrangle (northern half).Dips of the foliation are reported to be on the order
of60 to 80 degrees from vertical.Dr.Blake's Raleigh West N.C.map,showing
the foliation,is included in the map pocket (see Figures).Note that the Alcatel
site is positioned just offthe eastern central portion of the Raleigh West map.The
aforementioned Topographic Location Map can be used as a siting reference since
a slight overlap exists between quadrangles.
The orientation ofthe foliation is critical as weathering creates planes of weakness
in the rock along this foliation.As ground water flows along the weathered
foliation planes,plume geometry can be greatly affected.Deeper ground water
flow and plume geometry at the site appear to be affected by the foliation as both
exhibit strong north~northeast/south-southwest preferences.
4.5.3 Ground Water Flow
Water level data obtained from the monitoring wells has been used to determine
ground water flow directions and general ground water trends.These data have
been utilized to generate graphical representations ofthe water table and hard rock
potentiometric surface within the study area.The water table surface is
graphically represented on the Water Table Surface Map (see Figures).The
Alcatel Network Systems RFI

•
bedrock potentiometric surface is graphically represented on the Bedrock
Potentiometric Sutface Map (see Figures).Both maps were generated from
water level data collected on July 26,1995.
Ground water flow at the water table surface trends towards the west-southwest,
along a relatively uniform gradient.As compared to previous studies,the trends
associated with flow direction and hydraulic gradient appear to remain constant
regardless of season.Well hydrographs (Appendix C)further support this
conclusion.Shallow ground water flow appears to be influenced by the small
unnamed stream traversing the western portion of the property.Matching of
stream elevations and ground water flow lines results in a plausible configuration,
as shown on the Water Table Sutface Map.The remnant foliation in the saprolite
does not appear to contribute to a preferred flow direction as the trend of the
foliation and water table flow direction differ by at least 45 degrees.
Homogenation during advanced weathering may be responsible for this
observation.
A structural contour map of the bedrock surface was constructed to evaluate the
effect of the hard rock surface on the water table orientation.Upon examination
ofthe Bedrock Structural Contour Map and the Water Table Sutface Map (see
Figures),a similar orientation is noted for each surface.Thus,orientation ofthe
hard rock surface appears to influence the gradient and flow direction of shallow
ground water.
The pore water velocity in unconsolidated media (seepage velocity)is calculated
by the formula shown below.

•'...1"1
For the unconsolidated materials of the PWR and saprolite units,i,,,across the
study area was determined to be 0.02;K"was estimated to be approximately 15.0
ft/day from pumping test and previous slug test data (see Section 4.7);and n.«is
generally accepted to be approximately 20%.From these values,a mean seepage
velocity of 1.5 ft/day for the unconsolidated material is calculated.A lower
seepage velocity,on the order of 0.3 ft/day,results from the sole use of slug test
data obtained during previous studies.
As shown on the Bedrock Potentiometric Surface Map (see Figures),the ground
water flow direction within the bedrock is generally southwest,with an apparent
"trough"existing in the potentiometric surface beneath the Alcatel main building.
As bedrock wells have not been monitored for an extended period of time,it is
difficult to say if the "trough"is a seasonal phenomenon or a perennial feature.
In the event the trough is a perennial feature,it is likely caused by localized
differential weathering.This speculation is further supported by the greater
relative thickness of the PWR in this portion of the site.Additionally,a higher
transmissive zone would be expected to have a similar "fingerprint"on the
potentiometric surface.
The velocity of laminar flow within the fractured rock can be approximated in a
mathematical method similar to that for the unconsolidated material,in that the

variables i.." Kh,(horizontal hydraulic conductivity of the bedrock),Dr (fracture
porosity)are utilized.For the bedrock,i....across the study area was determined
to be 0.01;K",was assumed to be 2.8 E"ftlday (Freeze and Cherry,1979,p.409);
and D t was assumed to be 1.0 E~(Freeze and Cherry,1979).Entering these values
into the equation presented above yields a velocity of 0.3 ftlday for the bedrock.
This value is consistent with the slow recovery of bedrock monitoring wells
observed during well sampling activities.Additionally,this value may be typical
of bedrock at a depth of 40-60 feet below grade,however,velocity at a depth of
80-100 feet would be expected to be significantly less.
Vertical ground water flow information was obtained through comparison ofwater
level elevations at twelve well nests throughout the site.To graphically depict
vertical flow relationships across the site,a Water Level Elevation Difference
Map (see Figures)was constructed from water table and bedrock water level
elevation data.Contours on the referenced map indicate the relative difference in
water level between the upper and lower portions of the aquifer.Elevation,or
total head,differences that are positive indicate an upward hydraulic gradient
(upward ground water flow)while negative head differences indicate a downward
gradient.
Note that vertical flow on the western portion of the site is upward,in response
to the unnamed stream which traverses this area.Towards the center of the site
and eastward ground water flow is generally downward.As will be discussed in
the following section,this vertical relationship assists in understanding the
distribution of ground water constituents throughout the aquifer.

•
Most of the shallow (water table)wells on the Alcatel property have been in place
for several years,which has allowed for the collection of time-series data
regarding water levels at the site.Water level data have been plotted as
hydrographs (see Appendix C).Examination of these graphs indicate the water
levels in the wells demonstrate only minor seasonal fluctuations.With the
exception of wells MW-3s and MW-12s,which are located near the stream,a
slight declining water level trend is noted in several wells over time.This is due
largely to recent years of reduced recharge by precipitation.Lowering water
levels cannot be attributed to the nearby pumping of ground water,as the local
area is provided water via a public water system.
4.5.4 Ground Water Quality
Thirty-one monitoring wells and recovery wells RW-1 and RW-2 were sampled
on November 30 -December I,1994 (December 1994)to establish ground water
quality conditions at the site.While many of the monitoring wells were sampled
multiple times prior to this date,the December 1994 sampling represents the most
recent data for the entire site.Ground water samples were analyzed for 1,1-
Dich1oroethane (DCA),1,2-Dichloroethane (2-DCA),1,1-Dichloroethene (DCE),
1,1,1-Trichloroethane (TCA),1,1,2-Trichloroethane (2-TCA),Trichloroethene
(TCE),Tetrachloroethene (PCE),copper and lead as specified in the RFI
Workplan.Table 5 (see Tables)summarizes the December 1994 sampling event
and contains previous sampling event data.
Analytical results from the December 1994 sampling event were used to generate
two ground water quality VOC isopleth maps,one for the water table (saprolite
hydrolithologic unit)and one for the bedrock hydrolithologic unit.Total VOC

'.
isopleths were derived by summing voe constituent concentrations reported for
each well (see Laboratory Analytical Results,Appendix A).Water table and
shallow well ground water quality data were used to generate the Water Table
VOC Isopleth Map.Deep well data were used to generate the Bedrock VOC
Isopleth Map (see Figures).On each respective map,wells not used for
generation ofthe isopleths have the designation (NI)for Not Included.Due to the
low concentrations of copper and lead as compared to EPA risk-based
concentration data,isopleth maps for copper and lead constituents were not
generated.
The total voe plume at the water table appears as a roughly symmetrical,
elliptical feature (see Water Table VOC Isopleth Map)having a longitudinal axis
oriented northeast-southwest.The plume encompasses approximately 9.75 acres
in lateral extent.In the bedrock,the lower extent ofthe plume also appears as a
sub-symmetrical,ellipsoidal feature (see Bedrock VOC Isopleth Map)with a
longitudinal axis oriented north-south.The lateral extent of the bedrock plume
encompasses approximately 10.5 acres.
It is evident that plume geometry is controlled primarily by ground water flow,as
the longitudinal axis of each plume is roughly parallel to the principle flow
direction.This relationship is constant upon examination of previously reported
data for the site.Furthermore,the longitudinal axis of the bedrock plume is
roughly parallel to the foliation trend of the area.The lateral axis of each plume
is approximately two times the longitudinal axis.One difference between the
plume geometries is the steep concentration gradient along the westem boundary
of the bedrock plume.This feature is likely an artifact of the positive head

•
difference (discharge area)between the lower and upper portions ofthe aquifer in
this area.
The likely origin for the VOC plume is in the vicinity of MW-13 and Area 3 of
AOC #1.Minor spills of TCA were known to have occurred in the vicinity of
Area 3 in the early to mid-1980s and it is suspected that PCE releases occurred
near the juncture of the original 1958 and the 1963 and 1973 building additions
(see Building Additions Diagram,in Figures).As Alcatel personnel report no
known use of PCE at the facility,this constituent was likely introduced to the
subsurface through improper waste handling practices during the early operational
history of the plant.Decay products of both TCA and PCE are seen in the
analytical data.
The U_S.EPA's Risk Reduction Environmental Laboratory's (RREL)Treatability
Database (ver.5.0)was examined for specific gravity and solubility data.As
constituent concentrations near the solubility limit indicate saturation,and thus,the
potential of free-phase product,the difference between actual constituent
concentrations and reported solubilities is important.Data indicates that the target
compounds have solubilities ranging from 150 mg/L to 8690 rngIL (Table 9,see
Figures).Comparison of site laboratory analytical data with the RREL solubility
limit indicates none of the VOC concentrations are near the solubility limit.This
suggests that the free-phase product does not exist at the site.
Knowledge of the approximate date ofTCA releases (assumed to be 1984)allows
a comparison of apparent constituent velocity with calculated ground water flow
velocity.From the isopleth maps and the laboratory analytical data,TCA is

known to exist at a distance ofapproximately 960 feet down-gradient ofthe source
area.With elapsed time set at 10 years (1994-1984),0.26 ftlday is calculated for
the velocity of TCA.The linear velocity as determined from pump testing is 0.3
ftlday,or about 115%of the apparent velocity.The difference between the two
is attributed to many factors including but not limited to aquifer anisotropy,
retardation and dispersion.A similar comparison was not attempted for PCE as
the release date was unknown.
4.6 Stream Sampling
The stream transecting the western portion of the study area is a perennial stream which
receives baseflow from ground water and overland flow from precipitation events.The
stream crosses the study area with a length of approximately 1,250 feet.Much of the
stream now flows underground via galvanized steel culverts.As it crosses the Alcatel
property,a 370-foot length of the stream is exposed and accessible for sampling.The
stream is characterized by an essentially straight channel which has been artificially
modified.The bedload of the stream consists of sand-sized sediment and rip-rap blocks
which have fallen into the stream from the engineered banks.Native crystalline rock is
present in the stream bed in the northern portion of the study area.
Water depths at baseflow conditions varied from apprOXimately one to six inches,with
the apparent average depth being three inches.The average width of the channel at
baseflow conditions is approximately four feet.Accounting for channel geometry,a
cross-sectional flow area of 0.5 fl2 was calculated.The set of stream flow measurements
described in Section 3.4 were obtained for estimation of stream flow velocity during
baseflow conditions;the geometric mean ofthese measurements is 31.9 ftlmin.Using the
preceding data,baseflow discharge was calculated from the relationship shown below.

where:
Q••=(WDS)V
Q••is baseflow discharge
W is the width of the channel
D is the water depth
S is the channel shape factor (0.5)
V is the stream flow velocity
Page 42
·,
The resulting baseflow discharge is 15.9 ft'/minute or about IZO gallons/minute.
Two water samples were collected from the stream to assess water quality in the stream.
Sample CS-I was collected approximately ten feet south of the point where the stream
enters the Alcatel property (upstream of Outfall A).Sample CS-2 was collected at a
culvert (Outfall B)where the stream leaves the southwest portion of the Alcatel property.
Refer to the Water Table Surface Map for these locations (see Figures).Downstream
of Outfall B,the stream is contained entirely within the culvert.
Carbon disulfide,copper,and lead were detected in both creek samples.Carbon disulfide
was detected by Method 8240 analysis at concentrations of 11.0 uglL and 14.0 ug/L in
samples CS-1 and CS-Z,respectively.No other VOC compounds were detected.Copper
was detected at 2.5 ug/L and 3.5 ugIL in samples CS-)and CS-2,respectively;while lead
was detected at 1.7 ug/L and 1.1 uglL in samples CS-)and CS-2,respectively.From
these reSUlts,it may be concluded that the stream is not impacted by regulated constituents
form AOC #lIAOC #2,or any other portion of the Alcatel property.Complete analytical
results for the stream sampling are included in Appendix A.
4.7 AqUifer Testing
Data collected during the 72-hour aquifer test for pumping well RW-1 and observation
wells RW-2,MW-2sk,MW-Zik,and MW-4d were reduced using GWAP (Graphical Well

Analysis Package).Appendix C contains raw time and drawdown input data used for the
analysis.The resulting time-drawdown plot for each data set was graphically matched
against non-equilibrium reverse type curves for either phreatic or leaky-confined
conditions,depending on well screen position.A summary page showing the field data,
the matching non-equilibrium reverse type curve,match point values,well information
and the solution is provided for each of the five sets of data.Aquifer parameters
calculated from the five data sets are shown by the Aquifer Test Results table below.
Values for horizontal hydraulic conductivity (~)and transmissivity (T)have been
converted to daily units for clarity,storativity (S)is dimensionless.
Aquifer Test Results
Well Number K.(ft/day)T (fe/day)S
RW-I 19.89 596.45 0.1561
RW-2 17.97 359.42 0.0302
MW-2sk 12.60 226.80 0.0393
MW-2ik 40.59 1,217.81 0.0014
MW-4d 15.02 750.82 0.0130
The geometric mean hydraulic conductivity (K,,)from above is 19.40 ftlday.As the pump
test was designed to determine aquifer characteristics within the highest yielding zone of
the aquifer system,the resulting mean hydraulic conductivity value is representative of
this interval.Earlier slug testing results in the saprolite hydrolithologic unit provide a
mean hydraulic conductivity of 3.99 ftIday.In consideration of the thickness of the
saprolite unit,the thickness of the PWR and the upper fractured portion ofthe hard rock

for the site.

5.0 CONCLUSIONS AND RECOMMENDATIONS
Page 45
•
Through voluntary assessment actions previously conducted at the site and by implementation of
the October 1994 RFI Workplan,soil and ground water impacts at Alcatel's Raleigh,NC facility
have been assessed.This RFI focused mainly on AOC #2 as data deficiencies existed in previous
assessment efforts.Several assessment and remedial activities had occurred in AOC #I prior to
this investigation.
Results ofthe collective investigation identified minor VOC soil contamination remaining in the
vicinity of AOC #I Area 3.Concentrations of copper identified in AOC #2 soils are below
reported risk based levels.Previous remedial efforts within AOC #I have effectively removed
areas impacted by copper,lead and VOCs.
This investigation determined the lateral and vertical extent of the ground water VOC plume
identified during previous voluntary assessment actions.The approximate width,length and depth
of the plume is 500,1000 and 100 feet,respectively.Impacted ground water spans three distinct
hydrolithologic units.These units are the saprolite,PWR and hard rock.The linear flow velocity
of impacted ground water is on the order of 0.3 ftJday.This velocity agrees with the apparent
plume velocity for a known TCA release which occurred during the mid-I980s.Total VOC
concentrations within the center of the plume are on the order of 7000 uglL.Concentrations
attenuate sharply near the plume boundary.
Pathways for human consumption of regulated constituents are limited.The soil ingestion
pathway is practically non existent as remaining soil impact areas are covered by concrete or the
floor ofthe main building.Receptors in the ground water pathway are also limited.No ground
water production wells are located within two miles ofthe study area.Furthermore,Alcatel and
•the local area receive water from the municipal water distribution system.This system is fed by

a reservoir located 16 miles away.The only receptors in the local vicinity are the unnamed creek
which traverses the western portion of the Alcatel property and Crabtree Creek located about
4/IO-mile to the south.Water quality sampling of the unnamed creek does not confirm impact
by regulated constituents from the Alcatel facility.Results ofthe passive soil gas survey indicate
little exposure to regulated constituents via the air pathway.
Demolition and redevelopment of the neighboring Keebler property is planned.In response to
this action and in consideration ofthe plume existing on the Keebler property,interim corrective
measures (ICM)are recommended to mitigate further downgradient migration ofthe vac plume.
rCM will likely be implemented on a voluntary basis so as not to interfere with development of
the neighboring property.rCM is expected to utilize two arrays ofground water recovery wells,
one situated in the high concentration portion ofthe plume and the other acting as a containment
barrier on the southern extent ofthe plume.Ground water injection will be required to balance
the water budget for the site.During planned redevelopment activities on the Keebler property,
several existing monitoring wells will be affected.Wells will be salvaged where possible.It is
anticipated that well nest 8k will be relocated further toward the southeast.
