O'Brien & Gere Engineers, Inc. (O'Brien & Gere) has been retained by Central Transport,
I
Inc. (CTI) to conduct additional investigations at their Charlott~ facility. The investigations were
i
outlined in a Ground Water Assessment Plan which was submitled to the State of North Carolina,
I
Department of Environment, Health and Natural Resources, Ditision of Solid Waste Management
'
(State) on April 30, 1993. The investigations were conducted J response to a letters dated April
I
I
1 and May 12, 1993 from the State to "determine the vertical exl:ent of the plume" which has been
detected in the vicinity of MW-7 (See Figure 1). This monitorfug well is located near two former
lagoons located at the CTI Charlotte terminal site.
Brie1fly restated, the results of the previous investiga,ions conducted at the site have
indicated that ground water contamination exists in the vicinity Jt MW-7. The direction of ground
i
water flow :is to the southwest on the eastern portion of the sit~. The results of a fracture trace
analysis (See Report dated November 1990) suggest that one fracture lineation is present at the
Charlotte siite and apparently underlies the naturally occurring! depression in which Pond 3 and
i
former Lagoon 2 are situated. The general ground water gradietjt in the fracture at the site is from
'
north to south. The fracture system separates two distinct grohnd water flow regimes. Ground
I
water flowing from the west and ground water from the east a~parently coalesce in this fracture.
I
Ground water in the fracture flows southward as it leaves the site~ Wells MW-11, MW-13 and MW-
16 are in a low area of the site where this change in ground Vl\ater flow direction is believed to
occur. This, together with ground water level data, indicates that wells MW-11, MW-13 and MW-16
are located downgradient of the former lagoons.

3.0l General i
The supplemental field investigations were cond,cted at the CTI Charlotte, North Carolina
facility from May 23 through May 27, 1993 (well instiation) and June 7 through June 9, 1993
(ground water sampling and elevation measurement). Iese field investigations included:
• the installation of an additional bedrock bonitoring well (MW-18);
• the performance of a field survey to h~rizontally and vertically locate the oew
bedrock monitoring well; j
• the measurement of ground water elevat ons; and
• the collection and analysis of one ro nd of ground water samples from ten
monitoring wells located at the site.
The following subsections describe the procedurjs implemented in conducting each of the
field investigations.

3.02 Monitoring Well Installation I
From May 23 through May 27, 1993, a bedrock onitoring well, designated MW-18, was
installed at the CTI facility at the location shown on Fi res 1 and 2. This monitoring well was
installed to provide additional information for evaluating the local ground water flow direction and
I
quality at the facility. The drilling for the bedrock mon~~oring well borehole and well installation
' I wen: performed by McCall Brothers, Inc. of Charlotte, ~orth Carolina using an air rotary drilling

On Monday, May 23, 1993 a boring was complete to 60 feet and a six-inch protective casing
was installed and grouted in place to 60 feet. The b rehole was located midway between the
location of MW-7 and MW-17. When it was attemp ed to deepen the borehole through the
protective casing the following day, the fonnation im ediately below the end of the protective
casing collapsed and the driller was unable to keep the borehole open. The borehole was
abandoned by filling the protective casing with grout an , installing a concrete cover at the surface.
A second six-inch protective casing was installe4 to a depth of 88 feet below the surface.
Thi:1 borehole was located approximately 15-20 feet sof h of MW-17. The casing was grouted in
place and the borehole was advanced through the cas,g. A small amount of ground water was
detected at approximately 123 feet below the surface. iter consultation with Ms. Laurie Martin,
Hydrogeologist of the State of North Carolina, the bor~hole was extended to 130 feet below the
surface. A 2 inch diameter, 0.01 slot PVC screen was installed from 110 to 130 feet below the
surface. A clean sand pack was installed in the annulair space between the well screen and the
bornhole. This sand pack extended from the base of the borehole to a height of approximately two
'
feet above the top of the well screen. A two-foot thick btjntonite seal was then placed on top of the
sand pack. The remaining annular space between the bJrehole wall and the well casing was filled
'
with a cement grout. The grout extended to the ground surface, where a sealing cap with a lock was
placed on the well and a protective flush mount cover with concrete pad was installed over the well.
The well construction diagram for monitoring well MW-18 is provided in Figure 5. Table 1
summarizes the well specifications for monitoring well ?vfW-18.
The well was developed for approximately 3.5 hq~rs using air lift with an in-line air filter.
I
The drill cuttings, plastic sheeting and developmbt water were placed in storage drums,
labeled and left on site for disposal by CTI.

The shallow ground water in the Charlotte area o urs in the clayey to sandy soil as an
unconsolidated water table aquifer. The unconsolidated aqu er acts as a reservoir which transmits
water to the bedrock. The bedrock ground water is conta ed in the joints, fractures, cleavage
planes, bedding planes, and solution channels in the rock (IJegrand, 1952). The flow of
ground water within the unconfined aquifer is dictated by topography; in other words, the surface
of the water table roughly mimics the land surface. Within the bedrock aquifer, however, ground
water flow is controlled by the system of joints and fract~res (Legrand, 1952). Although the
' I underlying bedrock is recharged with ground . water that, has been transmitted through the
overburden, there is apparently insufficient recharge to maintain a continuous saturated zone above
the bedrock.
Two flow regimes appear to exist on the site. The ground water flow direction on the
western side of the former lagoons is to the east toward the fracture and ground water flow
directiorn on the eastern side of the former lagoons is southwest toward the fracture. The
topography of the site suggests that the two flow regimes merge in the fracture south of the former
'
' lagoon 2 and ground water leaves the site flowing in a southerly direction. Prior to January 1992
I
I
CTI sporadically operated a production well which is in the vic~ity of MW-15. During its operation
I a second flow pattern existed on the eastern side of the site. ; The practical effect of pumping the
production well was to create a hydraulic gradient away from the lagoons, and toward the
production well. The production well has not been operated since Westinghouse Remediation
Services, Inc. completed the lagoon excavation in January 1992. It has been observed that shutting

off the production well allowed the ground water flow direction to return to its natural, generally
southward trend.
It should be noted that in a fractured bedrock aquifer, both a hydraulic pathway and
hydraulic potential are needed for ground water flow to occJ. A pathway can be a joint or fracture
I
in the bedrock. Potential is indicated by ground water elevatfons, with potential ground water flow
from higher to lower elevations. Data has been collected ref arding potential and pathways. (See
November 1990 report). 1

I
'The bedrock ground water elevation map (Figure 2) illustrates the hydraulic potential from
the June: 7, 1993, ground water elevation data collected from bedrock monitoring wells MW-6, MW-
7, MW-8, MW-9, MW-10, MW-11, MW-13, MW-15, MW-16, MW-17 and MW-18. This is
consistent with data collected in previous investigations.
Figure 6 provides a vertical cross section through w~lls MW-7, MW-17, MW-18, MW-13,
MW-16, MW-11, and MW-12. Previous investigations have in~icated components of horizontal and
I
vertical ground water flow. Evidence of a downward groun1 water flow potential is given by the
fact that ground water is at a lower elevation in the deeper wt at the well nest at MW-7 and MW-
17 (i.e. the ground water elevation in MW-7 is higher that the elevation in MW-17). This is
consistent with the well nests' relative position to the presumid location of the fracture.
Data collected during this investigation indicates a popr hydraulic connection between the
I
water be~•ringzones where MW-7 and MW-17 are screened an1d where MW-18 is screened. During
'
' installation of MW-18, a less fractured, drier confining zone approximately 35 feet thick (between
'
88 feet and 123 feet below grade) was observed. Ground wa~er elevations were 717.86 feet MSL
in MW-18 and 752.38 feet MSL in MW-17. Temperatures co+cted during ground water sampling
were approximately 80 degrees fahrenheit in wells MW-7 and\MW-17 and were approximately 75

degrees fahrenheit in well MW-18. The temperature and ground water elevation differences
support the conclusion that there is poor hydraulic connection between MW-17 and MW-18.
iEstimated bedrock ground water flow velocity was previously reported to be 0.38 ft/day or
138 ft/year (see November 1990 report).

SECTION 5 -GROUND WATER OiUALITY
' Ground water sampling has been conducted at the site sfuce October 1989. Details of these
activities are included in previous reports including the Hydrogeplogic Investigation, June 1990, the
Supplemental Phase 1 Hydrogeologic Investigation, November 1990, subsequent letter reports dated
July 11, 1991, January 17, 1992, and September 15, 1992, and a Ground Water Assessment Report
dated March 1993. Table 2 summarizes the results of grou~d water sampling that has been
'
conducted at the site. Ground water samples were analyze~ for volatiles, base neutral/ acid
extractable:1, pesticides/PCBs and metals. Volatiles and base nbutral/acid extractables have been
detected in wells MW-7 and MW-8 and were detected in MW-17 in the one round of sampling
conducted in February 1993 after its installation. (Ethyl benze@e was detected in MW-16 on one
of four sampling rounds and is considered aberrational). Constituents detected on one or more
occasions in MW-7 include 1,4-dichlorobenzene, vinyl chloriqe, benzene, 1,1-dichloroethylene,
I
I ethylbenzene, toluene, 1, 1, 1-trichloroethane, xylenes, chloroethane, chlorobenzene, 1,2-
dichloroethene and napthalene at a range of 2 ppb to 110 ppb. Constituents detected in MW-8
include acetone, methylene chloride, 1,1,1-trichloroethane, benzene, 1,1-dichloroethylene,
tetrachloro•:thene, trichloroethene at concentrations from 4 ppb to 320 ppb. Constituents detected
in MW-17 include acetone, 1,2-dichloroethene and 1, 1-dichloroethylene at concentrations of 20, 31
'
and 6 ppb respectively. Acetone was detected in the sample fro~ MW-18 at a concentration of 11
I
ppb and wa:s detected in the field blank at the same concentration. Toluene was detected at a
concentration of 6 ppb, however given the poor hydraulic connection between the water bearing
zones when: MW-7 and MW-17 are screened and where MW-18 is screened, this is believed to be
unrelated to the contamination which has been detected in MWi-7 and MW-17.

I
i
August 6, 1993
The sum of investigations conducted to date irldicate a limited area of ground water
I
' contamination in the vicinity ofMW-7, MW-8 and MW-q. Data collected during this investigation
i
indicate that MW-18 represents a clean vertical boundary,! and, as depicted on Figure 3, wells MW-
1
I 6, production well, MW-16 and the intermittent stream pefine the clean boundary of the plume
I horizontally. No additional investigations are warranted. 'fhe clean boundary was established using
'
the r•esults of sampling in the wells and the stream.
'
I Site data have not documented significant cont~mination in wells to the south or west
I
( downgradient) of the lagoons. This conclusion is based primarily on the following:
' ' 1) Confirmation of ground water flow toward the south and west from the lagoons;
' I
2) Absence of contaminants in sampling wes~ of the lagoons;
I
3) No significant contamination detected sou[th of the lagoons in at least four rounds
4)
of sampling from wells MW-11, MW-13 anp MW-16, (eight rounds on MW-11) and
No contaminants detected in two rounds oJstream samples (See September 15, 1992
report).
