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 October 9, 2001 through October 12, 2001. However, analytical results for one sample, MW-38L, indicated detections of compounds never previously detected in that well as well as the absence of the one pesticide typically detected in that well. This well was resampled on January 10, 2002. Those results were consistent with historical concentrations in that well and results from the resampling event are presented in this report . Monitoring well MW-I ID was not sampled during this event because the well was dry. Findings of the monitoring results (Tables I and 2) include: Upper 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 and the initial downgradient area groundwater-sampling event (August 1995) . • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • C extraction system are below the maximum BHC isomer concentrations forecasted for the Upper Black Creek aquifer by the transport model (see Table 3) . I rnver Black 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 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 0.033 ug/L. The detection of dieldrin in MW-38L is not considered Site-related . • 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 . • BHC levels in the Lower Black Creek aquifer are near or below the maximum concentrations forecasted by the transport model (see Table 4 ) . \tream 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, demonstrate that pesticides in downgradient area groundwater do not extend to Aberdeen and Ray's Mill Creeks . • 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 less than previous 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 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-06, SW-07, SW-08 and SW-11-2 from Aberdeen Creek . Gamma-BHC, heptachlor and heptachlor epoxide were not detected in the surface water samples collected from Aberdeen Creek. The concentrations are comparable to historical monitoring results and are at levels that are protective of potential human and ecological receptors . • The highest concentrations of pesticides in Aberdeen Creek were detected 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 similar among surface water samples collected from Aberdeen Creek at locations downstream and upstream of the confluence with McFarland's Branch, • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • C 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 . Pn"vore Well S111Yey • 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 RA WP, monitoring of the downgradient area will be conducted every six months during years four and five of the remedy . The next monitoring event will be conducted during April 2002 . Olin Corporation has recently appointed a new Project Coordinator, Ray Hom, for the Geigy Chemical Corporation CERCLA Site.
