August 26, 1987 AGS 87053-1 <br /> Reynolds and Brown, Tracy, California <br /> ANALYTICAL RESULTS <br /> - Four of the soil samples collected, S-0820-1, S-0820-2 , S-0820-3 , <br /> and S-0820-4, were tested for total volatile hydrocarbons (TVH) <br /> and the volatile hydrocarbon constituents benzene, toluene, <br /> ethylbenzene, and total xylenes (BTEX) (EPA Method 8020) , and <br /> total extractable hydrocarbons (TEH) (modified EPA Method 8015) <br /> by Applied GeoSystems' laboratory. Ground water sample W-0820-5 <br /> was also analyzed by Applied GeoSystems for TVH and BTEX by EPA <br /> method 502 and for TEH by modified EPA Method 8015. Copies of <br /> laboratory records of all analyses are included in the Appendix <br /> of this report. The results of these analyses are presented in <br /> Table 1. <br /> ` The results of these analyses indicate that there is no <br /> detectable contamination of the soil present below the former <br /> tanks, and only very low levels of contamination of ground water. <br /> 4 Only benzene was detected at concentrations in excess of action <br /> levels recommended by the California Department of Health <br /> Services for drinking water. <br /> 5 <br /> ,opo/ied GeOSysteinS <br />
