Stamuface TweatiSation Report <br /> cW&. a*«m Property, Trey,cw <br /> L Project No.WWI <br /> January 15,1993 <br /> U Groundwater <br /> Laboratory analysis indicated that the <br /> contained' "!i Cohn 'Wil Bit IM M i <br /> Benzene and TPHOG were reported as nondetectable in the <br /> groundwater sample. Results of the groundwater laboratory analyses are summarized in <br /> Table 1. <br /> �,. Appendix B contains the laboratory data sheets, QA/QC data, and chain of custody <br /> documentation. <br /> 7.0 CONCLUSIONS <br /> Based on the results of this investigation, RESNA concludes that: <br /> l • Soil samples collected from borings SB-1, SB-11, and SB-19 were reported as <br /> nondetectable (not detected at or above method detection limits) for total petroleum <br /> hydrocarbons as oil and grease (TPHOG) and benzene, toluene, ethylbenzene, and <br /> xylenes (BTEX). <br /> • The groundwater sample collected from boring SB-11 was reported to contain <br /> j toluene (13 pg/ f), ethylbenzene (3.4 pg/ f) and xylenes (22 Pg/ f). Benzene and <br /> j, TPHOG were reported as nondetectable. <br /> • Based on nondetectable laboratory results and no obvious petroleum product odor <br /> or staining of the soil samples collected on the southern property boundary, <br /> oca <br /> approxi e y det' o die soutemperty undary. <br /> • Based on the low levels of volatile organics present in the groundwater sample <br /> L • <br /> collects fin boring SB-11161 <br /> o Iowever, the levels"184 are we below the State Primary r <br /> Maximum Contaminant Levels for toluene (2,000 pg/ f), ethylbenzene (680 Pg/ t)' <br /> and xylenes (1,750 jug/ 1). <br /> REPORTM121892.P& 5 <br />
