RE: Fifth Event, Second Quarter 1999 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 second quarter 1999 downgradient area
monitoring event (the fifth 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 second quarter monitoring event were collected April 12, 1999 through April 15,
1999. Monitoring results (Table I) indicate that the remedy continu~s to be protective of potential
human and ecological receptors, as well as area streams. Findings that support this conclusion
include:
I Tpper Black Creek Aquifer
• Pesticide concentrations in monitoring wells located west of the groundwater extraction
system (i.e., in the downgradient area) are 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 a concentration of 0.1 ug/1 in the groundwater sample collected on
April 14, 1999 from monitoring well MW-34D, and at a concentration of 0.13 ug/l in a
confirmatory sample collected from MW-34D on June 15, 1999. No otherTCL pesticides were
detected in the April 14, 1999 or June 15, 1999 samples 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).
Tower 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-31L and MW-32L; August 1995 for all other wells).
• Pesticides were not detected in well MW-36L as part of this or previous quarterly sampling
events for this well. Well MW-36L was installed to serve as a sentinel monitoring point for
Town Well No. 2.
• With the exception of BHC isomer concentrations reported for MW-27L and an estimated
beta-BHC concentration reported for MW-22L, 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.
• As predicted by Site groundwater flow and transport model simulations conducted for the
Downgradient Groundwater Remedial Action Work Plan, BHC isomer concentrations in well
MW-31L have experienced a slight increase due to the migration of peak BHC
concentrations towards Aberdeen Creek. The BHC isomer concentrations at MW-3!L
continue to be protective of groundwater concentrations at wells immediately downgradient
of this general area (MW-32L and MW-38L).
• Pesticides were not detected in wells MW-32L and MW-39L, which adjoin Aberdeen and
Ray's Mill Creeks, respectively. Dieldrin was the only constituent detected in well MW-38L,
located adjacent to Aberdeen Creek, at an estimated concentration of 0.054 ug/L. Dieldrin
was not detected at any other monitoring well in the Lower Black Creek aquifer.
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 the
constituents found in Aberdeen Creek surface water samples and demonstrate that pesticides
in downgradient area groundwater do not extend to Aberdeen and Ray's Mill Creeks.
• Pesticides were not detected above the reported sample quantitation limits in the surface
water sample collected from the headwaters of McFarland's Branch (SW-01).
• Alpha-, beta-, delta-and gamma-BHC were detected at surface water locations SW-02 and
SW-03 in McFarland's Branch. Concentrations detected at each location are nearly identical
to previous quarterly monitoring levels, and slightly less than the concentrations reported for
these locations during the June 1996 monitoring event. The 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.
• Estimated concentrations of alpha-, beta-and delta-BHC were detected in surface water
samples SW-04, SW-05, SW-07 and SW-08 collected on April 12, 1999 from Aberdeen
Creek. Laboratory quality control problems were associated with the analysis of Aberdeen
Creek surface water SW-06, collected on April 12, 1999. SW-06 was therefore re-sampled
on June 15, 1999. Estimated concentrations of beta-and delta-BHC were detected in this
surface water .sample at levels comparable to those reported for surface water samples

collected from SW-04, SW-05, SW-07 and SW-08 on April 12, 1999.
• Surface water and groundwater analytical results collectively reveal that the pesticides
detected in Aberdeen Creek are not Site-related. Aberdeen Creek surface water results reveal
that surface water concentrations arc 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 lies upstream of SW-08 and 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
Branch, thereby further indicating that the estimated levels of pesticides in Aberdeen Creek
are not attributable to Site conditions.
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.
The Companies are reviewing preliminary results for the third quarter 1999 monitoring event and
anticipate that the data will be reported to the Agencies next month. If you require additional
copies of the enclosed materials, or have any questions about the monitoring results, please contact
me at (423) 336-4479.
