ADDENDUM TO THE
RI/FS WORK PLAN
GEIGY CHEMICAL CORPORATION SITE
ABERDEEN, NC
Task 12 -Ground Water Investigation
12.1 Monitoring Network
Based on the results of the initial hydrogeologic investigation conducted at the site, an
expanded ground water assessment program is necessary to further characterize the
hydrogeologic conditions and contaminant distribution at the site and vicinity. As part of
this expanded assessment program, seven shallow monitoring wells (Wells MW-7S through
MW-13S) will be installed to further delineate the lateral extent of site-specific contaminants
and to evaluate the presence of regional contaminants in the uppermost (water table)
'•
aquifer (Figure 1).' The seven shallow monitoring wells will be located in off-site areas to
the north and south which are downgradient or potentially downgradient of the limits of the
existing monitoring well network. As an additional task, two deep on-site monitoring wells
(MW-14D and MW-15D) will be installed within the intermediate aquifer at the locations
shown in Figure 1. These wells will be located in the eastern portion of the site in areas
which are upgradient of the existing monitoring well network.
In addition to attempting to delineate the areal extent of contaminants, the locations of the
seven shallow monitoring wells will also provide supplemental information on stratigraphy
and the lateral continuity of the uppermost aquitard. The well borings will be drilled to the
top of this aquitard. The seven shallow monitoring wells will also provide water level data
which will be used to determine the ground water flow pattern in the vicinity of the site. In
particular, the shallow monitoring well locations will provide an expanded network of water
level data points that is needed to determine ground water flow directions around the
topographic divide at the site. Three of the shallow monitoring wells (MW-7S, MW-8S, MW-
9S) will be installed north of the site at positions which are located north of this topographic

divide. These wells will serve to define ground water flow and to assess potential
contaminant migration to the north of the site. In the event a northwest component of
ground water flow exists at the site, these monitoring wells would be positioned
downgradient of existing wells MW-2S and MW-3S, where shallow ground water
contamination has been detected, and the east end of former Warehouse A, where potential
source areas of contaminated soil were located.
The four shallow monitoring wells to be installed south of the site (MW-10S, MW-11S, MW-
12S and MW-13$) will allow a determination of the ground water flow pattern associated
with a topographic basin in that area. The axis of the topographic basin, located
approximately 200 feet south of the railroad tracks, may coincide with a ground water
divide. This divide is anticipated to parallel another probable ground water divide located
directly beneath the site. Thus, for the area located south of the railroad tracks and north
the topographic basin, the ground water flow direction in the shallow aquifer is anticipated
to be to the south or southwest. The ground water flow direction in the shallow aquifer
located south of the topographic basin is anticipated to be to the northwest. The proposed
southernmost monitoring well (MW-11 S) would therefore allow an assessment of ground
water quality south of the topographic basin.
The two deep monitoring wells (MW-14D and MW-15D) will be installed in order to better
understand upgradient site boundary conditions and to assist U.S. EPA in determining the
source of the regional presence of trichloroethene in the intermediate aquifer. The location
of these wells in relation to existing wells MW-1 D, MW-4D and MW-6D will enable the
calculation of the hydraulic gradient and ground water flow direction within the intermediate
aquifer near the eastern site boundary.
The shallow monitoring wells are anticipated to be drilled by the hollow-stem auger method.
The deep monitoring wells are anticipated to be drilled by hollow-stem and/or mud-rotary
methods. Except as noted below, the drilling methods, well construction, and well
development procedures will be the same as for the initial monitoring well drilling program
as described in Section 12 of the RI/FS Work Plan. Soil cuttings generated during the

installation of monitoring wells will be containerized and stored on-site pending the results
of analyses for site-specific parameters.
The newly installed shallow monitoring wells will be sampled and analyzed for Target
Compound List (TCL) pesticides and volatile organic compounds. Where appropriate,
selected wells from USGS well cluster GS-02-02 will be sampled for TCL pesticides. The
ground water sampling procedures in Section 12 will be followed. Ground water samples
will be collected from the shallow monitoring wells in accordance with Section 12.1 o of the
RI/FS Work Plan.
The two newly installed deep monitoring wells will be sampled and analyzed for TCL
pesticides and volatile organic compounds.
In order to further evaluate whether the detection of trichloroethane in Phase I RI monitoring
wells MW-4D and MW-6D is site related, ground water samples will be collected from well
PZ-1, existing D-series monitoring wells, and the Allred and Powder Metals Products wells.
The Allred and Powder Metal Products wells are located hydraulically upgradient of the site.
Ground water samples from the above wells will be collected in accordance with Section
12.10 of the RI/FS Work Plan and analyzed for TCL volatile organic compounds.
A summary of the proposed ground water analytical program for this phase of the RI is
presented in Table 1.
