No gasoline or other petroleum compounds were detected in the <br /> sample from 35 feet in the same boring. <br /> tGroundwater <br /> The groundwater sample from the soil boring B-1 was submitted for analysis at <br /> California State Certified Laboratories'; (Sherwood Laboratories in. Hilmar, <br /> DHS#1400). The sample was analyzed as"follows: <br /> • Total Petroleum Hydrocarbons as Gasoline (EPA Method 8015(m), I� <br /> • Benzene, Toluene, Ethyl Benzene and Xylene (BTEX by EPA Method 602) <br /> • Methyl t-butyl Ether ((MTBE) by EPA Method 8260). <br /> • Total Extractable Petroleum Hydrocarbons (TEPH) by EPA Method <br /> 351018015m <br /> 2937 Veneman Ave.,#B240 Geo-Phase Environmental Inc.
