Confirmation samples tested from - <br /> p SB I show that the sediments <br /> below the depth of 25 feet at this location are-free of detectable petroleum <br /> hydrocarbons. This depth is where a soil sample collected from the bottom of <br /> the remedial re-excavation (RE-BS-25 feet) which tested positive for <br /> petroleum hydrocarbons. <br /> The depth -- <br /> p to groundwater at this site (approximately �- feet- see attached <br /> Figure 3 Water Level Map) suggest that any remaining hydrocarbons above 25 <br /> feet should not pose a threat to groundwater. An approximate 30 foot buffer <br /> may exist between the last detectable contamination in the excavation and the <br /> water table. <br /> Geological Technics Inc. concludes that evidence gathered during this <br /> investigation suggest that groundwater study is not warranted. <br /> Therefore, Geological Technics Inc. recommends that no further action take <br /> place and that this site be considered for closure. <br />�f - <br />
