RE: Eleventh Event, Fourth Quarter 2000 Downgradient Area Monitoring Report
Geigy Chemical Corporation CERCLA Site
Aberdeen, North Carolina
Dear Giezelle:
In accordance with the Downgradient Groundwater Remedial Action Work Plan (RA WP), please
find attached one copy of the analytical results for the fourth quarter 2000 downgradient area
monitoring event (the eleventh in a series of twelve quarterly monitoring events scheduled for the
initial three years of the remedy). To facilitate your review, analytical data summary tables and
figures showing detected concentrations at sample locations are attached .
Samples for the fourth quarter monitoring event were collected October 11, 2000 through October
15, 2000. Monitoring results (Tables 1 and 2) indicate that the remedy continues to be protective of
potential human and ecological receptors. Findings that support this conclusion include:
Upper Rinck Creek Aquifer
• Pesticide concentrations in monitoring wells located west of the groundwater extraction
system (i.e., in the downgradient area) remain comparable to levels found during previous
monitoring events. The lateral extent of pesticides exceeding groundwater performance
standards in the Upper Black Creek aquifer continues to be less than that observed during the
initial downgradient area groundwater-sampling event (June 1996 for wells PZ-5, MW-31L
and MW-32L; August 1995 for all other wells) .
• Beta-BHC was detected at an estimated concentration of 0.12 ug/1 in the groundwater sample
collected from monitoring well MW-34D. No other TCL pesticides were detected in the
sample collected from this well.
• BHC isomer concentrations in monitoring wells located downgradient of the groundwater
extraction system are below the maximum BHC isomer concentrations forecasted for the Upper
Black Creek aquifer by the transport model (see Table 3) .

lower Block Creek Aqwfer
• The extent of pesticides in the Lower Black Creek aquifer is similar to conditions reflected by
previous quarterly monitoring events and the baseline sampling event (June 1996 for wells
PZ-5, MW-31L and MW-32L; August 1995 for all other wells) .
• Pesticides were not detected in well MW-36L, which serves as a sentinel monitoring point
for Town Well No. 2 .
• Routine monitoring conducted by the Town of Aberdeen continues to demonstrate that Town
Well No. 2 meets Federal and State drinking water standards .
• With the exception of BHC isomer concentrations reported for monitoring well MW-27L,
BHC levels in the Lower Black Creek aquifer are near or below the maximum concentrations
forecasted by the transport model (see Table 4). Analytical results for monitoring wells
surrounding MW-27L (i.e., MW-22L, MW-25L, MW-28L, MW-36L, MW-37L and PZ-3)
indicate that the BHC levels observed at MW-27L are limited in extent and therefore are not
anticipated to affect the remedy duration or level of protection .
• Pesticides were not detected in sentinel wells MW-32L and MW-39L, which adjoin
Aberdeen and Ray's Mill Creeks, respectively. Dieldrin was the only constituent detected in
sentinel well MW-38L, located adjacent to Aberdeen Creek, at an estimated concentration of
0.035 ug/L. The detection of dieldrin in MW-38L is not considered Site-related .
Stream Su if nee Water
• Analytical results for sentinel wells MW-32L, MW-38L and MW-39L, which monitor the
Lower Black Creek aquifer prior to its discharge to surface water, demonstrate that pesticides
in downgradient area groundwater do not extend to Aberdeen and Ray's Mill Creeks .
• Beta-BHC was detected in surface water sample SW-01, collected at the head of McFarland's
Branch. However, the concentration detected, 0.011 ug/L is below the reporting limit for that
compound. Alpha, beta-, delta-and gamma-BHC were detected at McFarland's Branch
surface water locations SW-02 and SW-03. Concentrations of BHC isomers detected at SW-
02 and SW-03 are similar to previous quarterly monitoring levels. Results of all isomers are
within the range of surface water concentrations estimated for these locations by the transport
model (Table 3-10 of the RAWP) and are at levels that are protective of potential human and
ecological receptors .
• Estimated concentrations of alpha-, beta-and delta-BHC were detected in surface water
samples SW-04, SW-05, SW-06, SW-07, SW-08 and SW-11-2 from Aberdeen Creek .
Heptachlor and heptachlor epoxide were not detected in the surface water samples collected
from Aberdeen Creek. Reported concentrations of alpha-, beta-and delta-BHC isomers are
within the range of surface water concentrations estimated for these locations by the transport
model (Table 3-10 of the RA WP). The concentrations are comparable to historical
monitoring results and are at levels that are protective of potential human and ecological
receptors .
• Pesticides were detected in Aberdeen Creek in an area that lies outside of the downgradient
extent of Site-related pesticides (i.e., surface water sample SW-08, located upstream of the
confluence with Ray's Mill Creek). This finding indicates the source of pesticides detected
in Aberdeen Creek is not Site-related .
• Pesticide concentrations are nearly identical among surface water samples collected from
Aberdeen Creek at locations downstream and upstream of the confluence with McFarland's
• • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • e • • • • •
Branch, thereby indicating that the estimated levels of pesticides in Aberdeen Creek are not
attributable to Site conditions .
• Surface water and groundwater analytical results collectively reveal that the pesticides
detected in Aberdeen Creek are not Site-related .
• Pesticides were not detected in surface water samples collected from Ray's Mill Creek .
Private Well Smvey
•
•
A survey to identify newly installed residential water supply wells was performed as part of the
quarterly monitoring event by driving each road in the downgradient area and conducting a
visual inspection of the properties to locate pump houses and/or well heads. No newly installed
private wells were identified .
On January 26, 2001, the Companies contacted Terry McNeil (Director, Moore County
Department of Health) to discuss permitting of private water supply wells in Moore County .
Mr. McNeil stated that the Health Department has not historically issued, nor does it currently
issue, well permits for private water supply wells. Mr. McNeil further stated that the
Department does not keep track of new well installations in any way. Mr. McNeill indicated
that the Health Department will begin issuing permits in 2001 in an effort to track private well
installations. In the interim, the Companies will continue to maintain contact with Town of
Aberdeen officials, including frequent communication with the Town of Aberdeen Public
Works Director, to determine if additional residential wells in the downgradient area have been
installed .
If you require additional copies of the enclosed materials, or have any questions about the
monitoring results, please contact me at [phone] .

1. Based on August 1995 sampling event. Maximum concentration measured in MW-11 D (alpha, delta, and gamma-BHC) and
MW-18D (beta-BHC).
2. Simulation results represent average adsorption properties and calculated half lives.
3. Simulation results represent baseline conditions requested by EPA during 5/14/96 meeting.
4. Simulation results represent average adsorption properties and sensitivity analysis of half lives ( +200 percent).
5. Simulation results represent slowest anticipated concentration decrease with time (sensitivity analysis of adsorption ( +50-60
percent) and half lives (+550 percent)).
Retardation factors vary due to chemical-specific partition coefficients and range in {., values.
