INTERNATIONAL TECHNOLOGY CORPORATION <br /> In March, IT generated a work plan for the installation of three new groundwater monitoring <br /> wells, two vadose wells and a soil vapor collection system. The work plan submitted to San <br /> Joaquin County in March and implemented in April through August 1991. <br /> Results of the investigation revealed that both groundwater and unsaturated soils had been <br /> impacted by petroleum hydrocarbons. Maximum hydrocarbon concentrations in soil were <br /> encountered near the former fuel dispenser and piping locations and in the south wall of the <br /> former fuel tank excavation. Distribution of hydrocarbons in groundwater is consistent with <br /> the measured direction of groundwater flow. <br /> In December, 1991, 1T was contracted by BP Oil Company to conduct a pilot study to <br /> examine the applicability of soil vapor extraction (SVE) as a remedial alternative for <br /> petroleum hydrocarbon impacted soils. IT was also contracted to further investigate <br /> groundwater quality. As the groundwater phase of the investigation is on going, it will be <br /> discussed under separate cover. The following report details SVE test methods, calculations <br /> and conclusions. <br /> IV#)03-10-92JUST)0WbIER 2 <br />
