To facilitate your review, analytical data summary tables and figures showing detected concentrations at sample locations are attached . Samples for the third quarter monitoring event were collected July 20, 2000 through July 24, 2000 . Monitoring results (Tables I and 2) indicate that the remedy continues to be protective of potential human and ecological receptors. Findings that support this conclusion include: I Jppcr 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 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 0.043 ug/1 (below the Site groundwater beta-BHC performance standard) 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) . I awer Black Creek Aqnifer • 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, MW-38L and MW-39L, which adjoin Aberdeen and Ray's Mill Creeks . 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, indicate that pesticide concentrations in groundwater at these locations are below analytical detection limits. These results demonstrate that pesticides in downgradient area groundwater do not extend to Aberdeen and Ray's Mill Creeks . • Pesticides were not detected in surface water sample SW-01, collected at the head of McFarland's Branch. 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 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 . 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 arc 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 • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • ·• • • • • • • • • • • • e • C 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 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 .
