TABLE FOUR <br /> Summary of Chemical Analysis of WATER Samples <br /> Alcohols and Fuel Oxygenates <br /> All results are in parts per billion <br /> Other <br /> Boring Ethanol Methanol MTBE Oxygenates <br /> ------ ------ ------ ------ ------ <br /> BH-A < 10 < 10 <10 < 10-<20 <br /> Notes: <br /> Non-detectable concentrations are noted by the less than symbol (<) followed by the <br /> detection limit. <br /> No TPH-G, TPH-D, BTEX, alcohols or fuel oxygenates were detected in the <br /> groundwater samples. <br /> 6 . 0 CONCLUSIONS AND RECOMMENDATIONS <br /> The only hydrocarbons detected in any of the soil samples was 13 p p m <br /> TPH-D detected in the soil sample collected from 8.0-feet bgs in the boring. <br /> The laboratory reported that this concentration was late in the diesel range <br /> and did not resemble a diesel standard. No TPH-G, BTEX or fuel oxygenates <br /> were detected in this sample. No TPH-G, TPH-D, BTEX, fuel oxygenates or <br /> alcohols were detected in either soil samples collected from 13.0 and 18.0- <br /> feet bgs or groundwater samples collected from the boring. <br /> The 13 ppm TPH-D detected in the soil sample collected from 8-feet bgs in <br /> boring BH-A is considered a very low concentration and does not represent <br /> a threat to human health, the environment or groundwater quality since <br /> no hydrocarbons were detected in deeper soil samples and groundwater <br /> samples collected from the boring. <br /> Based on these findings, it is ASE's opinion that no further assessment or <br /> remediation is warranted at this site, and ASE recommends that this case <br /> be closed by the SJCPHS-EHD. <br /> 7 .0 REPORT LIMITATIONS <br /> The results of this assessment represent conditions at the time of the soil <br /> and groundwater sampling, at the specific locations at which the samples <br /> were collected, and for the specific parameters analyzed by the laboratory. <br /> Hanson Property Report - August 1998 <br /> -5- <br />
