Samples were analyzed by Lancaster Laboratories,Inc.,for TPHd using method CALUFT-DRO/8015B Modified and TPHg using method <br /> N.CA LUFT Gasoline.TPHd analysis was performed without a silica gel-preparation procedure. Benzene,toluene,ethylbenzene, <br /> and total xylenes were analyzed using EPA Method 8021B. <br /> 2. Not sampled due to the presence of separate-phase oil. <br /> 3. Insufficient water in the well to sample. <br /> 4. The duplicate sample was labeled differently on the chain-of-custody form. <br /> 5. Well located on Western Farm Service Property. <br /> 6. TPHg and BTEX results are reported for the samples collected on February 14,2006. TPHd and PAH results are reported for the sample collected on March 30,2006. <br /> 7. The observed sample pattern includes#2 fuel/diesel and an additional pattern that elutes later in the DRO range. Page 2 of 2 <br />
