RE: Draft Seventh Event, Fourth Quarter 1999 Downgradicnt 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 1999 downgradient area
monitoring event (the seventh 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 12, 1999 through October
14, 1999. Monitoring results (Table I) indicate that the remedy continues to be protective of
potential human and ecological receptors. Findings that support this conclusion include:
l Tpper Black 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 down gradient area groundwater-sampling event (June 1996 for wells PZ-5, MW-31 L
and MW-32L; August 1995 for all other wells) .
• Beta-BHC was detected at a concentration of 0.097 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.
• 4,4'-DDD, which was detected in groundwater samples collected from MW-11D, MW-18D,
MW-22D and MW-30D for the third quarter 1999 monitoring event,. was not detected in
samples collected from these wells for the fourth quarter 1999 monitoring event. The
detection of this constituent in the groundwater samples collected from these wells for the third
• • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • 1• • • ·:
quarter 1999 monitoring event is therefore considered to be non-representative of long-term Site
conditions .
• 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) .
T ower Black Creek Aquifer
• 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-3 IL 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. The detection of beta-BHC at MW-36L during the third quarter 1999
monitoring event is therefore considered to be suspect and non-representative of long-term
Site conditions, as historical monitoring data demonstrate that pesticides have otherwise not
been detected in groundwater samples collected from this well .
• 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 wells MW-22L and MW-27L,
BHC levels in the Lower Black Creek aquifer are 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
0.043 ug/L. The detection of dieldrin in MW-38L is therefore not considered to be Site-
related .
• Dieldrin and 4,4'-DDD, which were detected in groundwater samples collected from well
MW-22L for the third quarter 1999 monitoring event, were not detected in groundwater
samples collected from well MW-22L for the fourth quarter 1999 monitoring event. The
detection of dieldrin and 4,4'-DDD at MW-22L during the third quarter 1999 monitoring
event is therefore considered to be non-representative of long-term Site conditions, as
historical monitoring data demonstrate that these pesticides have otherwise not been present
in this well.
Stream Surface 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, were non-detect for
pesticides and demonstrate that pesticides in downgradient area groundwater do not extend to
Aberdeen and Ray's Mill Creeks .
• Pesticides non-detect in surface water sample SW-01 at the head of McFarland's Branch .
Beta-, and delta-BHC were detected at surface water location SW-02 on McFarland's Branch .
Concentrations detected at SW-02 are nearly identical to previous quarterly monitoring
levels, and slightly less than the concentrations reported for these locarions during the June
1996 monitoring event. Results are within the range of surface water concentrations

estimated for these locations by the transport model (Table 3-10 of the RA WP) and are at
levels that are protective of potential human and ecological receptors .
• Alpha-, beta-delta-and gamma-BHC were not detected in surface water samples collected
from Aberdeen Creek .
• Surface water and groundwater analytical results collectively reveal that the pesticides
detected in Aberdeen Creek are not Site-related .
Private Well Survey
• 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 .

~utes:
1. Based on August 1995 sampling event. Maximum concentration measured in MW-11D (alpha, delta, and gamma-BBC) 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 halflives ( +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 f,.. values.

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).

Retardation factors vary due to chemical-specific partition coefficients and range in foe. values.
