TPH-d was detected in soil samples collected from beneath the north-ends of both <br /> USTs,product piping and stockpiled soil at concentrations ranging as high as 5,100 parts per million <br /> (reported as milligrams per kilogram: ppm). <br /> I <br /> BTEX constituents were not detected above laboratory reporting limits in any, of the analyzed soil <br /> samples. The analytical results of selected soil samples are summarized in Table 1. The laboratory <br /> report(AAL Batch No. 98-0930-019 and PEAL Lab Sample I.D.PE3685-01)and chains-of-custody <br /> forms are presented in Appendix F and Appendix H. <br /> 4.0. FIELD INDICATIONS OF PETROLEUM- MPACTED SOIL <br /> During soil sampling activities,faint to intense petroleum hydrocarbon odors were noted from soil <br /> samples collected at the north ends of both USTs(Tank 1 -North and Tank 2 -North) and from all <br /> six stockpiled soil samples (SP-1 through SP-6). <br /> 5.0. LIMITATIONS <br /> Our professional services were performed using that degree of care and skill ordinarily exercised by <br /> environmental consultants practicing in this or similar localities. The findings were based mainly <br /> upon analytical results provided by an independent laboratory. Evaluations of the geologic/hydro- <br /> geologic conditions at the site for the purpose of this in estigation are made from a limited number <br /> of available data points(e.g. soil samples),and subsurfam conditions may vary away from these data <br /> points. No other warranty, expressed or implied, is made as to the professional recommendations <br /> contained in this report. <br /> Advanced GeoEnviron mental,Inc. <br />
