'Ille :Remedial Investigation/Feasibility sttrly (RI/FS) for the North
carolina state University (NCSU) lDt 86 site includes the preparation of
project planning reports, subccu1LLa<-tin;J procurement, site investigation,
data evaluation arrl risk assessment, arrl evaluation of potential remedial
alternatives. 'Ille NCSU lDt 86 site served as a disposal site for
chemical arrl low-level radioactive wastes generated in educational arrl
research laboratories at NCSU. 'Ille U.S. Environmental Protection Agency
(USEPA) Region N has identified NCSU as the sole responsible party.
Previous investigations of the site comucted by NCSU identified offsite
migration of =ntaminants in ground water. 'Ille results of these
investigations indicate the need for additional information =ncernin:J
the types arrl volume of waste material buried onsite, levels of
=ntamination in ground water arrl soil, arrl current arrl future public
health an::l environmental hazards posed by the site. 'Ille proposed RI is
designed to evaluate potential health arrl environmental risks arrl to
provide the infonnation required to evaluate arrl select renmial
alternatives to mitigate such risks.
'Ille RI includes sampling of ground water from existing nonitoring wells
arrl one nearby residential well; installation arrl sampling of seven new
monitoring wells; geological arrl hydrogeological testing; deep borings to
define depth to bedr=lc; definition of waste trerx::hes using geophysical
techniques arrl limited excavation; surficial arrl subsurface soil sampling
onsite arrl offsite; arrl identification an::l mapping of potential leachate
seeps. Records searches will be comucted to determine the types arrl
volume of waste disposed onsite arrl the locations arrl =nstruction
details of nearby private wells.

U.S. Envirornrental Protection kJerc:! (USEPA) in response to Work
Assigrnnent Number 64-46G7 un:ier Contract Number 68-01-7250. Preparation
of this Work Plan was accamplished p.u:suant to the Work Plan Memorarrlum
(WH-1) for the North carolina state University (NCSU) IDt: 86 site date:i
October 10, 1986, arrl approved by USEPA Region IV on November 5, 1986.
Canp Dresser arrl McKee, Inc. (CI:M) prepared a Forward Plannirg Study
(FPS) for the NCSU lot 86 site un:ler the USEPA REM II contract (Work
Assigrnnent 70-4LG5). ,'Ihe report, date:i August 26, 1985, included a
description of the site arrl vicinity, a SUl!U10rY of the history of site
operations, arrl a review of the data collected durirg previous site
investigations. 'Ihe FPS also identified information deficiencies arrl
data gaps as a b3.sis for development of subsequent rerredial investigation
(RI) activities. In addition, the study presente:i a preliminary
evaluation of rerredial alternatives for the site. 'Ihe FPS has been used
as the basis for this Work Plan, supplemented by data obtained recently
from NCSU arrl from the site visit perfo:rmed by ESE in October 1986.
'.Ille purpose of this Work Plan is.to describe the work that will be
perfonned to collect the data needed to define present arrl future health
arrl envirornrental risks arrl to evaluate potential rerredial alternatives.
'.Ibis Work Plan describes the technical S=!)e arrl presents an estimate:i
cost, level of effort (IDE) hours, arrl schedule for the COI1pletion of the
RI arrl feasibility study (FS) .
'.Ille primary objectives of the NCSU lot 86 site investigation are to:
o Locate arrl characterize the wastes disposed onsite to evaluate
contaminant migration potential arrl to assess remedial
alternatives/technologies relevant to source control.

of reroodial alternatives/technologies.
o Olaracterize geological an:l. hydrogeological parameters for
assessment of contaminant fate an:l. transport an:l. evaluation of
reroodial technologies.
'Ihe RI is designed to collect data to supplement infonnation previously
collected in other investigations an:l. to meet the objectives stated
above. Evaluation of reroodial alternatives will be based up:m both new
an:l. existing data. 'llle proposed RI will be performed in a single phase,
although a limited second-phase investigation may be required if groun::l
water an::ljor soil contamination are more widespread than anticipated;
however, this Work Plan does not include cost estimates for additional
sampling an:l. analysis activities.
'Ihe RI addresses the low-level radioactive disposal area in a limited
fashion due to difficulties in accessing NCSU records an:l. data for this
area. It is anticipated that these recorqs will be available for
examination in the early stages of the RI, at which time the need for
additional investigation will be determined. Proposed activities related
to the low-level radioactive disposal area include a detailed review of
disposal records an:l. 11Pnitoring data (to be provided by NCSU), limited

analyses of grourrl water samples for radioactivity, arrl geophysical
surveys to delineate the waste disposal trenches.
'lhe prinary focus of the proposed RI/FS is the chemical waste b.Jrial area
at the site. Waste disposal trenches will be defined usin;J geophysical
techniques with lilnited excavation to determine the disposition of wastes
in the trenches. Subsurface soil samples will be =llected adjacent to
the trenches to define the depth of soil =ntamination. Groun::l. water
samples will be =llected fran existing arrl new oonitorin;J wells on-arrl
offsite to define the extent of =ntaminant plume migration arrl potential
for =ntamination of offsite private wells. Geological arrl
hydrogeological testirg is proposed to describe the potential for
contaminant migration (as a basis for the fate an:i transport analysis of
the risk assessment) arrl for evaluatin;J the feasibility of remedial
alternatives ailned at managenent of =ntaminant migration. Samplin;J arrl
analysis of surficial soils onsite arrl offsite is proposed in the Work
Plan to determine the extent of =ntamination arrl the potential for
=ntaminant migration to potential htman arrl environmental. receptors.
'lhis Work Plan was prepared in a=rdance with USEPA arrl REM III
guidelines. 'lhe plan =nsists of six sections, including this
Introduction (Section 1.0). Section 2.0 is a surmnary of existing data,
including a brief site history arrl site description. Section 3.0
presents the scopin;J of the RI/FS, includin;J the project objectives, a
prelilninary risk assessment, prelilninary scopin;J of remedial
alternatives, determination of applicable or relevant arrl appropriate
requirements (ARAR.s) arrl data quality objectives (D';Ps), arrl scopin;J of
the RI. Sections 4.0 arrl 5.0 contain the detailed task plans for the RI
arrl FS, respectively, includin;J the rationale arrl basic requirements for
the study arrl procedures for evaluation of remedial alternatives.
Section 6.0 summarizes the estilnated schedule arrl budget for performance

3.0 SOJPING OF 'IHE RI/FS
C-REMNCSU2/WP3 .1
01/08/87
ESE has developed, consistent with recent USEPA guidan::e am policy, a
technical approach to perfoi:min;J RI/FS studies under the REM III
contract. 'lhis approach includes a f'oc1sed investigation in each stage
of the RI/FS process to ensure that the field investigation ex>llects the
data nee:led for the Endan;ennent Asses~ (EA) am for the evaluation
am selection of the most awropriate 'l"E!IIEdiaJ alternative(s). 'lhis
approach is interxled to produce data appropriate for their interxled use
am to avoid generation of data not "leCessa:cy for valid site
characterization or evaluation of 'l"E!IIEdial alternatives. 'lhis approach
also ensures that analytical am evaluative activities are perfo:cmed in a
tirrely am CX>St-effective manner.
'lhe following subsections identify the oojectives of the RI
(Section 3.1), provide a disa1ssi1J11 of ARAR am I:Q:ls (Section 3.2), am
des=i.be the scope of the investigation (Section 3.3). 'llle details of RI
implementation are presented in Section 4.0, am the Task Plan for the F'S
is presented in Section 5.0.
'lhe task stnJcture used in this Work Plan is based on the 12 staroard
RI/F'S tasks described in the menoramum fran USEPA's HazardaJs Site
Control Division (Jl.ll'le 12, 1986). 'lhis task stnJcture includes all
elements of the tasks outlined in the USEPA Region IV Statement of Work
dated September 15, 1986. 'llle staroard tasks, as used in this Work Plan,
am the tasks in the USEPA Statement of Work are cross-referenced in
Table 3-1.
3 .1 RI/FS OBJECI'IVES
'llle overall objectives of the RI/FS investigation for the NCSU Lot 86
site are to define risks to plblic health am the envi=unent, identify
the need for Expedited Response Action (ERA), am ex>llect data required

o Investigate the nature am extent of ground water contaminant
migration offsite to detennine actual or potential contamination
of private water suwly wells am surface waters. 'lhis
infonnation will be used to evaluate plblic health am
environmental risks am the feasibility of remedial
alternatives/technologies aimed at management of plume

o Cllaracterize geological am hytlrcgeological parameters for
assessment of contaminant fate arxl. transport arxl. evaluation of
remedial technologies.
Relevant to these objectives, several specific questions were considered
in developing the scope arxl. tQOs for the NCSU I.at 86 site RI/FS. F.ac:h of
the follow-ing questions is addressed in more detail in later sections of
this scoping dc:x::urnern:.
o What are the potential public health arxl. environmental risks
associated with soil arxl. ground water contamination in the
vicinity of the site? What is the potential for these
contaminants to reach water supplies or neru:by surface waters?
o What types arxl. quantities of chemical arxl. radioactive wastes are
present at the site? What are the bouooaries of the waste
disposal areas arxl. to what degree are the wastes containerized?
o Are any expedited response actions required to protect the
health of neru:by residents or to prevent further offsite
migration of contaminants via ground water or surface runoff?

o Which remedial alternatives may be app1.op1:iate for the site to
eliminate sam::e areas amjor to manage offsite migration of
contamination? What data are T'JeE'dei_to evaluate these
alternatives?
o What action levels established by ARAR are necessacy, or
appropriate, to minimize or eliminate potential adverse :inq:,acts
an health or the environment?
o What~ level is appropriate for infonnatian to support_risk
assessrne..+-. an:i remedial alternative evaluation?
o How can the appropriate quality ani quantity of data be 1IDSt
efficiently collectei an:i evaluatei in the RI?
Previoos investigations of the site conducted by NCSU have not adequately
defined the sam::e volume an:i characteristics or extent of offsite
contamination, either in groond water or soils, an:i available info:cnatian
suggests that groond water sanplin;J an:i analysis did not canfOl:111 to USEPA
stan::1ards for quality assurance/quality control (QA/QC) applied to data
used in an RI/FS. Available data are useful in definin;J the scope of the
RI by in:licatin;J a general plume configuration, but the data do not
appear adequate for canfit:min,l' the presence or absence of contamination
at low concentrations or for definin;J the vertical extent of aquifer
contamination. P\Jrther ilwestigatian is required to define m:,re
ccmpletely the horizontal an:i vertical extent of groond water
contamination offsite, to determine the extent of soils contamination
onsite an:i offsite, an:i to describe the types an:i disposition of onsite
chemical waste material.
3.1.l Prel:i:minary Risk Assessrrent
A preliminary risk ar:sessrnert was perfcmned to address the potential
public health an:i enviromental risks associatei with the NCSU Lot 86

evaluated, based on a review of available infor.mation. '.the nearest

drainage ditch locatai downslope an:i north of the site adjacent to Wade
Avenue Extension. 'Ille uses of neart,y surface waters will be investigatai
during the RI.
3.1.1.3 Soil Pathway--'lhe extent of soil contamination at the site has
not been detennined. Because wastes disposed of at the site ~ ocvere:i
with fill, contamination of onsite surface soils is not expected to be
significant. However, during the site recornldissance, a survey of
surficial soils (top 3 to 4 inches) inlicatai detectable volatile
organics in several locations as measured by the HNU meter. 'lllese
observations occurrecl. IICSt frequently in areas near the !CM-lying
northwest =rner of the site, where surficial soils have ercded. Further
investigation is required to determine whether this erosion is exposing
waste material resulting in offsite migration of =ntaminatai soil during
stonn events. As previously statai, the drainage ditch downslope of this
erosional area may" feed into neart,y surface water bodies.
Additional surface soil contamination may have occurred in two localized
areas onsite. Available information inticates that three drums of
transfo:aoor oil potentially contaminatai with polychlorinatai bii:nenyls
(FCBs) may have been stored onsite prior to offsite disposal. 'lhis
storage area is believed to be alO!l:l' the northenl boundary of the site
within the chemical waste turial area. Illring site reconnaissance, a
55--gallon drum lid was foon:i in the approximate vicinity of the storage
area. 'lhe area is also locatai in an erosional area, described
previously. If spills or leaks occurred during drum storage or
transport in the area, a pathway exists for =ntaminants to be washed
offsite in storm runoff, potentially contaminating neart,y surface waters.
A secon:l onsite area of potential soil contamination is the fo:aoor
chemical storage dl.mpster area. No evidence was foon:i during the site
reconnaissance to inticate soil contamination in this area (by visual
inspection or by HNU organic vapor survey of shallow soils). Potential

D.lring JxCOJ»lc'issanoe c:utside the site fenoeline, organic vapors at a
mu::enLiation of 15 ppn were detec:ta:i in one area on the northeast side

o:mtamination an::l b.lried, broken glass in::licate a possible spill, I.Jut
further investigation is warranted to detennine the extent of
o:mtamination in this area. HUman exposure to mntaminants in this area
may ooc:ur by direct mntact with soils, inhalation of organic vapors, or
.in:lirectl.y by migration of o:mtaminated runoff into surface waters near
the site.
Ambient measurements of radioactivity were taken durin;J the site
reccuu,,,Jssance both onsite an::l offsite. 'nlese measurements did not
in::licate the presence of radioactivity above backgrourxl levels in the
vicinity of the site. D.lring RI activities, measurements will be taken
c:x:mtinu=ly.
3.1.1.4 Air Pathway--'nie potential for chemical contaminant release into
the air is considered minimal if the site remains undisturtled. Ambient I air measurements with the HNlJ arourn the site shC1iled no o:mtamination
above backgrourxl for volatile organics. 'Iha only detectable releases

Altematives involving partial treatment of contaminants with contairment
of residuals will also be considered. 'llti.s Teroedial action may include
ccanbinations of the technologies diso1ssed previously with solidifi-
cation/stabilization of contaminated soils am capping. Because

12/22/86
In accordaroe with the stamaJ:d USEPA RI/FS tasks, the FS for the NCSO Lot 86 site will ccnsist of four tasks whicn will be conducted based an the results of the RI. 'lllese tasks are as follows:
Task 9-:RernediaJ Alternative Screenin;J,
Task lO-~ial Alternative EValuatian,
Task ll-Feasi.bility Stu:iy Bep:n.t, and
Task 12-Post-RI/FS Sufplr:t.
5.l REMEDIAL AlllmOO'IVE SCREENIN::; (TA&{ 9)
'llie first step in the FS process is conducted sil!lultaneously with the EA (Task 6) and the Data validation, :Reducl:icn, and EValuatian effort (Tasks 4 and 5). 'llie objective of this task is to refine the ran;re of response actions developed durin; the scopin:J p:cocss... 'lhls task will employ the data cx,llected in the Site Investigation (Task 3) and the results of the EA (Task 6). 'llie 61.lbtasks carprisin:J Task 9 will accomplish the foll~ objectives:
o Developrrent of remedial response objectives,
o Identification of aa,licable technologies and assemb1.y of alternatives, and
o SCreenin:J of rernedfoJ technologies/alternatives.
5.1.1 Ilevelopment of Remedial Response Objectives
Based on the data cx,llection in the RI and the contaminant migration pathways defined in the EA, the remedial response objectives will be developed.
Site specific response objectives will be developed usin:J a risk-'based methodology to define cleanup levels that would eliminate or minimize risks to plblic health and the environment. :EotentiaJ. contaminant migration pathways and el!pOSllr8 pathways, identified in the EA, will be examined fUrther as a basis for estil!latin:J acceptable residual

then be estbnated by extrapolatinJ fran reoept:or points back to so.iroe
areas, along critical migration pathways.
Devel01,i121xt of response a,jectives will also inclme :ref:inenelxt of ARARs
specific to the NCSO site.
5.1.2 Identification of Applicable Tec:hnolcxdes and Assembly of Alternatives
Based on the rerredlal response objectives, a list of applicable
technologies will be identified. 'Ihls list will contain technologies
previously diso•ssed in Section 3.0. After potential remedial
technologies have been aiosen, operable units will be defined for eadl
site condition requirin;J remediation. Each operable unit should meet at
least one response a,jective. After these operable units have been
compiled, any ~te i;tiasin;J of them will _be cansidered. Depel'ldin;
on site conditions and the adequacy of RI results, a i;tiased approach may
be desirable.
After operable units have been defined, reJTEdi al alternatives will be
identified. Each remedial alternative will be an cwerall site remedy.
'lhe no-action alternative will be cansidered as a :baseline against wch
the other alternatives can be evaluated. Alternatives wch can be
classified in each of the classes of alternatives required by the NCI?
will be identified.
5.1.3 Screening of Remedial Technologies/Alternatives
'lhe lists of technologies and alternatives discussed previously will be
screened. 'lhe a,jective of this effort is to eliminate frail further

Field activities planned for the NCSU Lot 86 site include site
i:e:::cnuiajssanoe, preliJDinary characterization, an:i sanplin; activities to
detennine contaminant 0.J1.::.e11t.Iations an:i migration in grc,.md water an:i
soil. 'Ihese RI activities are designed to provide data sufficient to
delineate sa.u:ce areas; contaminant types, distribution, an:i levels:
hydrcgeologic an:i geologic characteristics relevant to contaminant
transport: an:i actual or potential receptors.
If an evaluation of the data gathered in the RI indicates that additional
data are required to define fully the extent of o:mtamination an:i to
determine appropriate remedial alternatives, the rationale an:i
documentation for prcpose::l additional activities will be submitted to the
U.S. Environmental. Protection '/v:Jercj (USEPA) in the form of a Technical
Direction Meiroramum (Tr.M) before additional field activities are
initiate:i. 'Ihe prcpose::l approach to the NCSU RI/FS · involves only a

~ements will be made for leas.in;J a mobile office trailer that can be
deployed to the NCSU Lot 86 site area. A security perimeter will be
ccnstructed around the trailer. 'Ihis trailer will serve as ;, mmmard
post and· storage facility for performance of field sanpl.in;J and survey.in;J
activities. Present schedul.in;J requires the trailer to be deployed and
fully operational in advance of the cx:smnencement of excavation and
drill.in;J activities requir.in;J the use of the trailer. 'nle =unand post
will be maintained thlough the oarq;,letion of all major RI field
activities.
Concurrent with the establishment of the c:omman:i post, all required field
. sanpl.in;J and analytical equipnent will be obtained and tested or
calibrated as ¥CeSsazy to ensure that the equipinent is in sourxl. 'WOrk.in;J
order. 'Ihis equipnent will be deployed to the site on an as-TJeeded basis
for perfoi,nance of the respective field activities.
'nle Site Manager and Field Operations Team reader will "Werk to secure all
necessary state and local permits that will be required dur.in;J the RI
(e.g., lrater well drillinJ,/installation permits). 'nle Site Manager will
"Werk with USEPA Region IV to obtain site access agreements with NCSU. It
is urderstood that the sec:urinJ of site access agreements is the

'lhis stage of the ~ process is oavexed in FOP Sections 1.2 and 1.5.
3.6.2 stage ~Establishment of Analytical Data 9,lality
'lhe basic :requirement for the RI/FS is that data collected be of known
quality. Criteria used for definin;J data quality are:
o Precision-a measure of the repr, ,!ucibi.lity of analyses uroer a
given set of conditions,
o Accuracy-a measure of the bias that exists in a measurement
system,
o :Representativeness-the degree to which saJ!l)le data accurately
and precisely reprwent selected c:haraCU!ristics,
o Completeness-a measure of the amount of valid data obtained
fran a measurement system o:mq;,ared to the amcunt that was
expecte:l. to be obtained uroer normal conditions, and
o Comparability-an expression of the confidence with which one
data set can be o:mq;,ared to another.
Precision and accuracy are statistical ccncepts related to sampl.irq
design, methods,_ and materials. Precision is ireasured by collecting
duplicate saJ!llles and replicated analyses in order to define the sampl.irq
variance (or error) attrib.ttahle to environmental heterogeneity an:l,lor
the sampl.irq and sample preparation process. Accuracy, in tenns of
statistically estimat.irq the field concentrations, is a function of the
number of saJ!l)les. laboratory accuracy is a function of the method
detection limits (MDis) and percent reccvery. · Ar:oJr:ac-f is checked
thraJgh use of blanks and matrix spikes and assured by proper instnnnerrt:
calibration/certification.
'lhe accuracy and precision of sampl.irq data taken in this study will be
adequate tr> mmpare data against ms to be chosen for risk assessment
and feasibility studies. Potential ms for the RI/FS include:

'llle ARARs for the NC:SU Lot 86 site will be diSC!JSSed in greater detail in
the RI/F'S LE4X)rts. Representativeness of sanplinJ is also extremely
important for this =lgnnent. 'llle prcposed sanplinJ plan for the NC:SU
Lot 86 site is designed to ensure that sanplinJ locations are appl.opl...i.ate
and that a sufficient number of sanples are collected to neet the
objectives of the RI/F'S. 'llle rationale for selection of samplinJ
locations and number of sanples is provided in the Work Plan for the
RI/F'S. Prcp:lsed samplinJ techniques to ensure representativeness are
described in detail in the Work Plan and in this FSAP. C'alpleteness will
be assured by making f!NBrY effort to collect and analyze all samples that
are proposed to be collected.
3.6.3 stage 'lllree-Selection of Analytical and Sa:rrpling Options
'llle analytical options chosen for the site investigation include IQO
Levels I, III, 'IV, and v. 'llle specific level or analytical option chosen
is based on the IQO level for the specific type of sanple and data
needed-IQO Level I "10I'k consists of field screening for the selection
of sanplinJ location, for a preliminary estiJDation of contaminant concen-
tration, and for health and safety precautions. For Baltples that need a
high level of data quality but are not required for potential litigation,
IQO Level III will be used. Rigoro.is WQC protocols and doc:=entation
are required for sanples that may be used for confiLmatianal water
quality; Level 'IV will be used for these samples. San'q;>les LeqUirinJ
special analytical SBLVices (SAS) will be analyzed at IQO Ievel v.

2.0 HEALTH AND SAFETY PERSONNEL
2.1 HEALTH AND SAFETY PERSONNEL DESIGNATIONS
C-REMNCSU.1/HASP.2
12/31/86
The following briefly describes the H&S designations and general responsibilities which will employed for the NCSU Project. These titles are herein identified, and the responsibilities are consistent with analogous titles and responsibilities in the REM III Program. The titles have been established to accommodate the site needs and requirements in order to ensure the safe conduct of onsite work. The number and type of H&S personnel for the NCSU site is based on the project size and scope and the particular health and safety training requirements relative to the proposed site activities or operations. The NCSU site investigation will require one full-time HSO based on review of available site information.
2;2 COMPANY HEALTH AND SAFETY SUPERVISOR (CHSS)
The CHSS has overall responsibility for development and implementation of this HASP. He also shall approve any changes to this plan, modification of any procedures as required, or any new activities proposed. ·
The CHSS is responsible for the development of any new company safety protocols and procedures necessary for field operations and is also responsible for the resolution of any outstanding safety issues which arise during the site work. All health and safety-related duties and responsibilities will be assigned only to qualified individuals by Charles C. Haury, CIH, the ESE CHSS. Authorization for personnel to perform work onsite (i.e., relative to medical exams and training) must be cleared by the CHSS.
2.3 SITE HEALTH AND SAFETY OFFICER (HSO)
The HSO will be present onsite during all NCSU field operations at Level C or higher. The HSO will be responsible for all H&S activities. Where the site is identified as modified Level D, the HSO will direct the site H&S efforts through an H&S designee approved by the CHSS. He may direct or participate in downrange activities as appropriate when this does not interfere with his primary HSO responsibility. The HSO has stop-work authorization which he will execute upon his determination of an imminent safety hazard, emergency situation, or any other potentially dangerous situations (e.g., weather conditions,) where this action is appropriate. Authorization to proceed with work will be issued by the CHSS after such action. The HSO will initiate and execute all contact with support facilities and personnel when this action is appropriate.

3.0 SITE HISTORY AND PHYSICAL DESCRIPTION
3.1 LOCATION
C-REMNCSU.1/HASP.3
12/31/86
The NCSU site is located on Lot 86; west of Raleigh near carter-Finley Stadium in Wake County. Entrance to the site is approximately 100 feet (ft) south of the southern right-of-way of Wade Avenue Extension (Figure 3-1).
3.2 DESCRIPTION
The site covers an area of approximately 1.5 acres and was used for burial of radioactive and hazardous laboratory chemicals from 1969 to 1980.
Topography is gently rolling with broad, flat, interstream areas. surface drainage is to the northwest toward the extension and stadium parking lot, north to the highway, and to the east.
Radioactive waste was buried in the eastern half of the site, and laboratory chemicals were buried on the west side (Figure 3-2).
The site is overgrown with grass, and shrubs and east sides. The site is surrounded by a with a locked gate at the southwest corner. waste burial area is separated from the rest wire fence and locked gate.

chain-link fence
The. radioactive
of the site by a
An unnamed tributary to Richland Creek runs 400 ft east of the site, and a small pond lies about 1,600 ft west of the site. The dirt road leading to the site is used as a jogging path by university students and area residents.
The nearest water supply well is loc_ated about 2, ooo ft southeast of the site fence at the Medlin residence. Figure 3-2 shows burial areas, monitoring well locations, and site proximity to the Wade Avenue extension.
3.3 HISTORY
NCSU educational and research laboratories generated hazardous chemical and low-level radioactive wastes that were buried on Lot 86 of Farm Unit No. 1 from 1969 to 1980. The site was divided into two separate areas, as shown in Figure 3-2. The western half received the chemical waste, and the eastern half received the low-level radioactive waste in the form of animal carcasses.
Site activities are primarily concerned with the hazardous chemical waste burial area. NCSU has installed 24 monitoring wells at the site since 1982 (Figure 3-2).

The university maintains a listing of the types and ~antity of
materials buried at the site. From these records a list of
typical chemicals reported in the burials was compiled and is
presented in Table 5-1 (see Section 5.0 of this HASP). The
chemicals listed include solvents, pesticides, heavy metals,
acids, and bases.
The chemical wastes were placed in trenches located in the
northwest portion of the site. The trenches were approximately
10 ft deep and 50 to 150 ft long. After filling, about 2 ft of
cover material excavated from the trenches was used to close the
trenches. Later, the disturbed area was seeded with grass.
NCSU estimates that approximately 22 trenches totaling less than
2,000 linear feet were used. Although some of the liquid
chemicals disposed during the initial site operations were
poured into the trenches, both liquid and solid chemicals were
generally buried in metal, glass, or plastic containers. NCSU
estimates3the volume of buries hazardous waste at 890 cubic
yards (yd).
The low-level radioactive waste disposal area is regulated at
the Federal level by the Nuclear Regulatory Commission and at
the State level by the North Carolina Department of Human
Resources, Division of Facility Services, Radiation Protection
Section. There is also a NCSU Radiation Protection Commission.
According to Mr. D.W. Morgan of NCSU Radiation Protection
Office, radiological wastes were buried in trenches
approximately 6 ft deep with 4 ft of cover material. The
trenches have been mapped and waste disposal records are
available. Most of the waste is in a solid form, primarily
animal carcasses. These range in size from rats to whole sheep.
The carcasses were frozen when buried and were not ·
containerized. The most abundant radionuclide in the buried
material is tritium which has a half-life of 12.26 years. For
this half-life, after 5 years, 75 percent of the original
radioactivity remains. After 10 years, 57 percent remains.
Other radionuclides include carbon-14, iron-59, phosphorus-30,
and phosphorus-32. These four isotopes have half-lives of
5,730 years, 45.1 days, 2.5 minutes, and 14 days, respectively.
Of all these isotopes, the ones of greatest concern are tritium
and carbon-14 because of their longer half-lives. No fission
products were buried at the site.
In September 1984, NCSU acquired the capability of performing
volatile organic analyses on a routine basis using the purge and
trap method. Monitoring Wells (MW) 1, 2, 6, 7, 8, and 12 show
the greatest number of contaminants. Contaminant concentrations
are highest in Wells 1 and 6. There also appears to be a
pattern of increasing contaminant concentrations in these two
wells over the 6-month period from October 1984 to March 1985.

The most frequently detected compounds include benzene, carbon
tetrachloride, chloroform, 1,2-dibromoethane, dichloromethane,
1,2-dichloropropane, diethylether, ethylbenzene,
4-methyl-2-pentanone, toluene, 1,1,1-trichloroethane,
trichloroethene, and xylene. ·
The Medlin residence well and the 208 Marsh Avenue well were
sampled for volatile organics analyses on November 29, 1984.
Tetrachloroethene and xylene were detected in both wells at a
level of .10 micrograms per liter (ug/L). NCSU researchers
believe the presence of these compounds is the result of
laboratory contamination. These same compounds were also
detected in the blank run with the samples. Without knowing
more details regarding well construction and use at these
locations, it is difficult to correlate the analytical results
with results obtained at the site. Furthermore, these wells are
topographically upgradient from the site.

6.0 HAZARD ASSESSMENT
The potential for exposure to site personnel at the NCSU site is dependent on the particular task involved. Tasks include excavation and waste characterization, geophysics, soil sampling, soil boring, monitoring well installation, and ground water sampling.
The excavation activity task is the most hazardous task planned. In this task, a backhoe will be used to carefully reveal the contents of the buried waste. Potential exists for exposure to metals, alcohols, ketones, aldehydes, acids, phenolics, pesticides, amines, polynuclear aromatic hydrocarbons (PNAs), halogenated solvents, and other miscellaneous organic compounds. Some of those chemicals are known carcinogens (i.e., benzidene), extremely flammable (i.e., ethyl ether), or extremely toxic (i.e., cyanide compounds). The excavation task will be subcontracted to a firm specializing in this type of

activity. Included in the excavation task is limited character-
ization of the types and integrity of waste containers. This
activity wi~l be performed by the subcontractor. The subcon-
tractor will submit a separate safety plan the excavation and
characterization activites to be reviewed by ESE and the Ebasco
Zone Project Management Office (ZPMO). Activities will require
the use of, as a minimum, full Level c personal protection.
Level B capabilities will be available should monitoring
indicate the necessity to upgrade.
Other activities present hazards from the same group of
compounds, but to a lesser degree based on less disturbance of
buried materials. Splashing of contaminated ground water
directly on skin or breathing volatilized organic compounds are
two sources of exposure.
The overall hazard for the site is moderate, with the excavation
activity ranging from moderate to high. The potential for
chemical burns (corrosives) and fire (flammables) is also
present, especially during excavation activities.

8.0 ZONES. PROTECTION. AND COMMUNICATION
8.1 SITE ZONES (see Figure 8-1)
C-REMNCSU.1/HASP.9
. 12/31/86
The site is surrounded by a chain-link fence with a gate located near the southwest corner. The fence, a good physical barrier, will serve as the location of the hot line, except in the gate area immediately adjacent to the fence which will serve as a decontamination zone. The gate is the controlled access point through which field personnel will pass during site entry and exit.
8.2 PERSONAL PROTECTION
0.2.1 General
Level B protection will consist of hooded Saranexe coveralls, chemical-resistant steel toe boots and latex boot covers, chemical-resistant outer Solvexe gloves and inner latex gloves, and a full-face pressure demand air supplying respirator. The joints between the coveralls and boots and gloves will be sealed with duct tape. In addition, hard hats will be worn in the vicinity of all drilling operations.
Level C protection will consist of Saranexe coveralls, chemical-resistant boots and latex boot covers, chemical-resistant outer gloves (Solvexe) and latex inner gloves, and a full-face air purifying respirator (APR) with organic vapor and high-efficiency particulate absolute (HEPA) cartridges. The joints between the coveralls and boots and gloves will be sealed with duct tape. In addition, hard hats will be worn in the vicinity of all drilling operations.
If breathing zone measurements with the HNU PIO consistently indicate concentrations greater than 5 parts per million (ppm), field team members must upgrade to Level B or further define the organic vapor constituents with detector tubes.or other methods. HCN concentrations above 10 ppm also warrant upgrading to Level Bas measured by the Monotoxe HCN detector. Combustible gas concentrations greater than or equal to 25 percent of the lower explosive limit will warrant site evacuation until the source can be located and eliminated.
