WORKPLAN
FOR NCSU LOT 86
GROUNDWATER REMEDIAL DESIGN
1.0 STATEMENT OF THE PROBLEM
The North Carolina State University (NCSU) Lot 86 Site (Lot 86) is a 1 .5-acre site
located on the west side of Raleigh, North Carolina. The Lot 86 site served as a
disposal site for chemical and low level radioactive wastes generated in the
educational and research laboratories at NCSU from 1 969 to 1980. The wastes
were disposed in subsurface trenches and covered with native soils. The waste
deposited in the trenches is respons_ible for the groundwater and soil contamination
present on site.
The site was placed on the National Priority List (NPL) in October 1 984. A
Remedial Investigation Report was completed June 10, 1994. A Draft Feasibility
Study was prepared in February 1996. A Record of Decision (ROD) was issued by
the Environmental Protection Agency (EPA) on September 30, 1 996. EPA selected
groundwater pump and treat and in-situ soil mixing and encapsulation as the
remedy for this site.
Mid-Atlantic Associates, P.A. has been retained to prepare this Remedial Design
Work Plan (Work Plan) for groundwater remediation at Lot 86. The Work Plan will
be followed by preliminary and final remedial designs before groundwater
remediation is implemented at this site. The goal of the remedial action is to restore
the groundwater to its beneficial use. Groundwater contamination may be
especially persistent in the immediate vicinity of the contaminants' source,: where
concentrations are relatively high. The ability to achieve remediation levels at all
points throughout the plume cannot be determined until the extraction system has
been implemented, modified, as necessary, and plume response monitored over
time.
2.0 BACKGROUND SETTING
2.1 Site Description
The Lot 86 site is northeast of Carter-Finley Stadium and immediately south of the
Wade Avenue Extension right-of-way and is surrounded by state-owned property
(Figure 2. 1). The site is bound on the west by the stadium parking area and

surrounded by trees on the three remaining sides. The nearest water supply well is
reportedly located approximately 2,000 feet southeast of the site at the Medlin
residence.
Groundwater occurs in the silty clay/granular soils (residual and saprolite) and in the
underlying crystalline bedrock under generally waster table (unconfined) conditions.
The unconsolidated soils aquifer is chiefly replenished by the infiltration of
precipitation where the aquifer is exposed. The shallow unconsolidated residual
soil/saprolite water-bearing unit exists .at depths ranging from 20 feet to 40 feet
below land surface, and flows west/northwest toward Wade Avenue.
2.2 Site History
The Lot 86 site was used as a hazardous chemical and low level radioactive waste
disposal site beginning in 1969. The waste was generated in the University's
educational and research laboratories. The site was divided into two separate
areas as shown on Figure 2; 1; the western area received the hazardous chemical
waste, and the eastern area received low level radioactive waste. Burial of waste
was discontinued in November 1980, to comply with the regulations promulgated
under the Resource Conservation and Recovery Act (RCRA).
The chemical wastes were placed in trenches and covered with approximately two
feet of native soils. There are 22 trenches approximately ten feet deep and from
50 _to 150 feet in length. Types of chemicals buried at the site include solvents,
pesticides, inorganics, acids, and bases. NCSU reported that it had disposed of
approximately 11,000 cubic yards of chemical waste at the site. Quantities
reported included lightly contaminated soils and water as well as actual waste
materials.
Radiological wastes were buried in nine trenches approximately 6 feet deep and 50
to 120 feet long. The depth of wastes in the bottom of the trenches was reported
to be two feet with four feet of native soil cover material. Most of the waste was
in solid form, primarily animal carcasses ranging in size from rats to whole sheep.
Radionuclides present in the waste include tritium, carbon-14, iron-59, and
phosphorus-32.
The site was placed on the National Priority List in October 1 984, based on results
from an inspection completed in June 1984. '
2.3 Existing Data
A significant amount of site data has been collected during previous investigations.
Thirty-three wells were installed near the site prior to 1993 and ongoing .sampling

of these wells has been conducted since the early 1980s (Figure 2.2). In 1993,
eight new stainless steel monitoring wells were constructed during the Remedial
Investigation. Samples were collected from the eight new wells, 11 existing wells,
and one domestic well (Medlin residence). Groundwater analytical results from
these 20 wells are summarized in Table 2.1. In Table 2.1, the bolded analytical
results are actual measured levels, while the "less than" values indicate laboratory
detection limits. The minimum and maximum detected levels for each contaminant
in these 20 wells are summarized in Table 2.2.
Groundwater analytical results indicated that volatile organic chemicals (VOes)
were the most prevalent group with low levels of semivolatile organics and
pesticides detected. voe concentrations are notably higher in the shallow aquifer
than in the bedrock aquifer, with the highest concentration near the landfill. voes
were not present in background and upgradient wells. The highest dissolved voe
concentrations were detected in wells MW-37S, MW-36S, MW-5A, and MW-1 B in
the upper five to ten feet of the saturated zone, immediately west and northwest
of the landfill, nearest the disposal trenches. The highest concentrations measured
included: acetone -16,000 micrograms per liter (µg/1) in MW-36S; b1enzene
14,000 µg/I in MW-37S; carbon tetrachloride 6,400 µg/I in MW-37S, chloroform -
63,000 µg/I in MW-37S; methylene chloride -18,000 µg/I in MW-37S;
tetrachloroethene -5,000 µg/1 in MW-37S; and trichloroethene -1,300 µg/I in
MW-36S. Low levels of voes were detected in some of the deep wells.
All of the semivolatiles and pesticides detected in the groundwater were at low
level concentrations. Within the semivolatile organic group, three parameters were
detected in samples collected from three different wells. Bis(2-ethlyhexyl)
phthalate was detected at 41 milligrams per liter (mg/I) in the background well MW-
34D. lsophorone was detected at 570 mg/I in MW-37, and napthalene was
detected at 31 mg/I in MW-36S. Pesticides (chordane, dieldrin, and lindane) were
detected in shallow wells MW-34S, MW-35S, and MW-37, respectively.
The following metals were detected in downgradient wells at concentrations ,above
those present in the upgradient wells (maximum detected levels are in
parentheses): arsenic (110 µg/I), barium (960 µg/I), calcium (28,000 µg/I),
chromium 1 7 (~tg/1), cobalt (89 µg/I), copper (68 µg/1), lead (31 µg/1), magnesium
5,600 (µg/I), manganese (20,000 µg/1), nickel (73 µg/I), potassium (15,000 µg/I),
sodium (20,000 µg/1), zinc (660 µg/I).
All groundwater samples were analyzed for carbon-14 and tritium. earbon-14 was
detected in only in MW-38 above the detection limit of 500 pico-curies per liter
(pei/I) at 522 pei/1. Tritium was detected at three wells at concentrations ranging
from 711 pei/I to 6,000 pei/I, which are well below the Mel of 20,000 pei/1.

scope of the technical specifications will be outlined in a manner reflecting the final
specifications.
3.4 Plan for Satisfying Permitting Requirements
All activities will be performed in accordance with the requirements of applicable
federal and state laws and regulations. Disposal of soil cuttings and groundwater
will be handled by NCSU. Any off-site disposal will be in compliance with the
policies stated in the Procedure for Planning and Implementing Off-site Response
Actions (Federal Register, Volume 50, Number 214, November, 1985, pages
45933-45937) and Federal Register, Volume 55, Number 46, March 8, 1990, page
8840, and the National Contingency Plan, Section 300.400. If offsite disposal is
selected, an offsite disposal plan will identify any permits that are required, the
time required to process the permit applications, and a schedule for submittal of the
permit applications.
3.5 Draft Construction Schedule
A Draft Construction Schedule will be developed for construction and
implementation of the remedial action, which identifies timing for initiation and
completion of all critical path tasks. The schedule will specifically identify dates for
completion of the project and major milestones.
3.6 Final Pre-/Final Design
NCSU and EPA comments on the Preliminary Design and a memorandum indicating
how NCSU's and EPA's comments were incorporated will be included in the Pre-
final/Final Design. The Pre-final Design will be submitted when the design work is
approximately 90 percent complete, in accordance with the approved : design
management schedule. Comments generated from the Preliminary Design Review
will be addressed and any modification of the design as a result of incorporation of
the comments will be clearly shown. Essentially, the Pre-final Design will function
as the draft version of the Final Design.
After NCSU and EPA review and comment on the Pre-final Design, the Final ·Design
will be submitted along with a memorandum indicating how the Pre-final Design
comments were incorporated into the Final Design. All Final Design documents will

Data from the aquifer pumping test, including flow rates and drawdown in the
pumping test well and in nearby observation wells will be collected and
summarized. Additional data will include analytical tests to characterize soil
cuttings and collected groundwater.
Microsoft Access® will be used as the data management system for the Remedial
Design. All field and laboratory testing results will be entered into Access® to
facilitate efficient retrieval, sorting, and composing tables for importation into
reports. Although data may be manipulated to facilitate interpretation, the original
data will be available. on the original lab and field sheets, as well as in Access®
files. This approach will permit independent verification of results. All computer
data will be backed up daily onto magnetic tape, which will be stored offsite.
Access® is a flexible data management system; data formatting will be discussed
with NCSU before finalization.
Microsoft Office 97® will be utilized for most data management and reporting to
facilitate transfer and summary. Reports will be provided as electronic files
(Microsoft Word 97® and Excel 97®), as well as in hard copy. Schedule and
