' 27 November 2000 <br /> • AGE-NC Project No 98-0520 <br /> Page 3 of 3 <br />' TPH-g,TPH-d,BTEX, DIPE, ETBE, TAME and TBA compounds were not detected in the ground <br /> water samples from the site <br />' Analytical results from ground water samples are summarized in Table 2 The laboratory reports <br /> (MAI Laboratory ID 53212-53216), quality assurance and quality control (QA/QQ reports and <br />' cham-of-custody forms are included in Appendix B <br />' 4.0. SUMMARY AND CONCLUSIONS <br /> The following conclusions were drawn from the results of this investigation <br />' • The ground water flow direction in November 2000 at the site was toward the northeast <br /> • MTBE was detected an groundwater samples collected from two of the monitoring wells on <br /> Ithe site The detection of MTBE was less than the State of California-Department of Health <br /> Services maximum contaminant level <br /> I • TPH-d was detected in the ground water sample from MW-3 at a concentration of 77 �Lg/l <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 finding`s were based mainly <br /> upon analytical results provided by an independent laboratory Evaluations of the <br /> geologic/hydrogeologic conditions at the site for the purpose of this investigation are made from a <br /> limited number of available data points (i a soil and monitoring well ground water samples), and <br /> subsurface conditions may vary away from these data points No other warranty, expressed or <br /> Iimplied, is made as to the professional recommendations contained in this report <br /> I <br />
