GROUNDWATER REMEDIAL DESIGN
1.0 STATEMENT 01 THE PROBLEM
The North Carolina State University (NCSU) Lot 86 Site (Lot 86) is a 1.5-acre site
located on the west ~ide of Raleigh, North Carolina. The Lot 86 site served as a
disposal site for chelnical and low level radioactive wastes generated in the
educational and resea~ch laboratories at NCSU from 1969 to 1980. The wastes
were disposed in subsurface trenches and covered with native soils. The waste
deposited in the trenches is responsible for the groundwater and soil contamination
present on site.
The site was placed on the National Priority List (NPL) in October 1984. 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, 1996. EPA selected
groundwater pump arid 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) [tor groundwater remediation at Lot 86. The Work Plan will
be followed by preliminary and final remedial designs before groundwater
remediation is implemehted 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, mcidified, 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 Extensioh right-of-way and is surrounded by state-owned property
(Figure 2.1). The site i~ bounded on the west by the stadium parking area and

surrounded by trees oh the three remaining sides. The nearest water supply well is
reportedly located apbroximately 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 I
underlying crystalline bedrock under generally water table (unconfined) conditions.
The unconsolidated ~oils aquifer is chiefly replenished by the infiltration of
precipitation where the aquifer is exposed. The shallow unconsolidated residual
soil/saprolite water-be1aring unit exists at depths ranging from 20 feet to 40 feet
I 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 beginninb 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
I was discontinued in November 1980, to comply with the regulations promulgated
under the Resource cdnservation and Recovery Act (RCRA).
The chemical wastes lere placed in trenches and covered with approximately two I
feet of native soils. 1here 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 fo~r 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 1984, based on results
from an inspection conipleted 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 bJen conducted since the early 1980s (Figure 2.2). In 1993,
I eight new stainless steel monitoring wells were constructed during the Remedial
Investigation. Sample1s were collected from the eight new wells, 11 existing wells,
and one domestic w~II (Medlin residence). Groundwater analytical results from
these 20 wells are sJmmarized in Table 2.1. In Table 2.1, the balded analytical
results are actual me~sured levels, while the "less than" values indicate laboratory
detection limits. The r\iinimum and maximum detected levels for each contaminant
in these 20 wells are Jummarized in Table 2.2.
Groundwater analyticli results indicated that volatile organic chemicals (VOes)
were the most prev~lent group with low levels of semivolatile organics and
pesticides detected. \/Oe concentrations are notably higher in the shallow aquifer
than in the bedrock a~uifer, with the highest concentration near the landfill. voes
were not present in b~ckground and upgradient wells. The highest dissolved voe I 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; benzene
14,000 µg/I in MW-3~S; carbon tetrachloride 6,400 µg/I in MW-37S, chloroform -
63,000 µg/I in M'«-37S; methylene chloride -18,000 µg/I in MW-37S;
tetrachloroethene -5,000 µg/I in MW-37S; and trichloroethene -1,300 µg/1 in
MW-36S. Low levels bf voes were detected in some of the deep wells.
All of the semivolatilJs and pesticides detected in the groundwater were at low I
level concentrations. Within the semivolatile organic group, three parameters were
detected in samples I 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 w~s detected at 570 mg/I in MW-37, and napthalene was
detected at 31 mg/I in1 MW-36S. Pesticides (chordane, dieldrin, and lindane) were
detected in shallow wJlls MW-34S, MW-35S, and MW-37, respectively.
I
The following metals Jere detected in downgradient wells at concentrations above
those present in th1e upgradient wells (maximum detected levels are in
parentheses): arsenic I (110 µg/1), barium (960 µg/1), calcium (28,000 µg/1),
chromium 17 (µg/I), cobalt (89 µg/I), copper (68 µg/I), lead (31 ~Lg/I), magnesium
I 5,600 (µg/I), mangane'se (20,000 µg/I), nickel (73 µg/1), potassium (15,000 µg/I),
sodium (20,000 ~Lg/I), kine (660 ~Lg/I).
All groundwater samplL were analyzed for carbon-14 and tritium. earbon-14 was
I detected in only in MW-38 above the detection limit of 500 pico-curies per liter
I •
(peill) at 522 pei/1. T[ritium was detected at three wells at concentrations ranging
from 711 pei/I to 6,000 pei/1, which are well below the Mel of 20,000 pei/1.
