RE: April 2002 Sampling Event
Downgradient Area Monitoring Report
Geigy Chemical Corporation CERClA Site
Aberdeen, North Carolina
Dear Giezelle:
VIA QYEBNIGUI DEi JYEBY
On ·behalf of Olin Corporation, Syngenta Crop Protection, and Kaiser Aluminum & Chemical
Corporation (the Companies), please find attached one copy of the analytical results for the April
2002 sampling of the Geigy Site downgradient area. To facilitate your review, analytical data
summary tables and figures showing detected concentrations at sample locations are attached .
Samples for the monitoring event were collected April 9, 2002 through April 11, 2002. Findings of
the monitoring results (Tables 1 and 2) include:
Upper Black Creek Aquifer
• BHC isomer concentrations in monitoring wells located west of the groundwater extraction
system (i.e., in the downgradient area) are comparable to, or slightly less than, levels found
during the previous (October 2001) monitoring event.
• Trace levels ( estimated concentrations) of alpha-Chlordane, dieldrin, endrin ketone, gamma-
Chlordane, and heptachlor epoxide were reported at several locations for the first time during
the downgradient remedy. The estimated concentrations are at levels that are very near their
associated method detection limit and therefore may reflect instrument noise or non-Site
related sample carry-over rather than changes in groundwater quality conditions .

• Pesticides were not detected in sentinel wells MW-32L and MW-39L, which adjoin
Aberdeen and Ray's Mill Creeks, respectively. Aldrin, dieldrin and delta-BHC were detected
in sentinel well MW-38L, located adjacent to Aberdeen Creek, at estimated concentrations .
• BHC isomer concentrations in monitoring wells MW-31L, MW-32L, MW-37L MW-40L,
PZ-2, PZ-3 and PZ-5, which lie upgradient of area streams, are comparable to, or slightly less
than, levels found during the previous (October 2001) monitoring event.
• BHC isomer concentrations in monitoring wells MW-25L and MW-27L are higher than
levels found during the previous (October 2001) monitoring event, but are otherwise
comparable to, or lower than, all other preceding monitoring events .
• Pesticides were not detected in well MW-36L, which serves as a sentinel monitoring point
for Town Well No. 2 .
• Trace levels (estimated concentrations) of aldrin, alpha-Chlordane, dieldrin, endrin ketone,
gamma-Chlordane, and heptachlor epoxide were detected at select locations. The estimated
concentrations are at levels that are very near their associated method detection limit and
therefore may reflect instrument noise or non-Site related sample carry-over rather than
changes in groundwater quality conditions .
5ta'am S'urfoce Water '
• Alpha, beta-, delta-and gamma-BHC were detected at McFarland's Branch surface water
locations SW-01, SW-02 and SW-03. Concentrations of BHC isomers detected at these
locations are at levels that are protective of potential human and ecological receptors .
• Estimated concentrations of alpha-, oeta-, delta-, and gamma-BHC were detected in surface
water samples SW-04, SW-05, SW-06, SW-07, SW-08 and SW-11-2 from Aberdeen Creek,
and are at levels that are protective of potential human and ecological receptors. Alpha-,
beta-, and delta-BHC concentrations are comparable to monitoring results obtained for these
locations during October 2000 .
• Pesticides were not detected in surface water samples collected from Ray's Mill Creek .
Privot'! We{[ S'uryey
• 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 .
In accordance with the sampling frequency described in the approved Remedial Action Work Plan,
monitoring of the downgradient area will be conducted every six months during years four and five
of the remedy. The comprehensive monitoring event will be conducted during October 2002 .
