1.4.2 PESITCIDES <br /> 1.4.2.1 Bromacil <br /> Soil <br /> A total of 240 soil samples was collected and ana�zed for bromacil. Seventeen <br /> of the samples consisted of surface soil grabs, and the remaining 223 samples <br /> were collected from 91 soil borings. Sample locations generally corresponded to <br /> j locations of monitor wells contaminated above criteria levels and/or adjacent to <br /> t suspected soil contaminant source locations. Bromacil was detected in only 2 of <br /> the 223 boring samples and in 1 of the 17 surface samples. Boring Sample 7-A, <br /> located near a railroad spur track in the North Balloon Area, contained bromacil <br /> at a concentration of 2.16 gg/g. Boring Sample 82-A, located near MW cluster <br /> 413 in the western part of the North Balloon Area, contained bromacil at a <br /> concentration of 4.60 gg/g. Surface grab soil Sample 5-10 contained bromacil at <br /> a concentration of 2.06 gg/g. All other samples analyzed for bromacil were <br /> below the USATHAMA CRL of 0.97 gg/g. Offpost soil sampling and analyses'for <br /> bromacil were limited to the two background surface grab Samples 5-16 and <br /> 5-17. Bromacil concentrations in both samples were below the USATHAMA CRL <br /> of 0.097 gg/g. State of California criteria currently do not exist for.bromacil in <br /> i <br /> I soils. <br /> 1-76 <br />
