Grantline and East Roads Page 4 of 8 <br /> near an existing diesel UST:, the soil samples from Borings # 1 and <br /> was also analyzed for TPH(as diesel)/BTEX- EPA Method 3550/8015. <br /> The soil sample from Boring # 6 was analyzad for TPH(as gasoline), <br /> TPH (as diesel), oil and Grease(Standard .Method 503 .D & E), and <br /> Volatile Organic Compounds(EPA Method 8240) . These sampling <br /> parameters are requited by the Cali-ornia Water Quality Control <br /> Board for investigation of UST's. The analytical results for <br /> TPH(as gasoline) and TPH(as diesel) are shown in the attached <br /> Figure 2 entitled " TPH (as gasoline) Map". The BTEX <br /> concentrations are shown in Figure 3, entitled "BTEX Map". The <br /> analytical results are also presented in the table below <br /> ANALYTICAL SAMPLE NUMBER <br /> RESULTS <br /> r' <br /> Bl-1 B2-1 B3-1 B4-1 B5--1 B6-1 <br /> TPH (as <br /> gasoline) N.A. 500 <br /> in mg/Kg (Parts . 1300. 730 1700 3.8 <br /> per million ppm) Detection Limit 2.5 ppm <br /> TPH (as diesel) N.D.
