SUMMARY AND CONCLUSIONS <br /> Based upon data collected from the site, AGE concludes the following <br />' • TPH-d was detected in one soil sample(B 1-5)at a concentration of 10 m Other petroleum <br /> P PP <br /> hydrocarbons were not detected in any soil samples collected at the site The hydrocarbon <br />' Impact to soli appears to be very limited <br /> • TPH-d was detected in grab water samples at concentrations as high as 2,700 ppb <br /> • MTBE was detected at concentrations as high as 25 ppb, below the Central Valley Regional <br /> Water Quality Control Board recommended closure limit of 35 ppb <br /> I <br /> 6.0. RECOMMENDATIONS <br /> Based upon data collected from the site, AGE recommends the following <br /> No further investigation of the UST area is warranted at this time <br /> 7.0. LIMITATIONS <br /> IOur 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 upon field <br /> I measurements and 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 probe boring soil and ground water samples) and <br /> subsurface conditions may vary away from these data points No other warranty, expressed or <br /> implied, is made as to the professional recommendations contained in this report <br /> I <br /> Advanced GeoEn%ironmental,Inc <br />
