The property is a gasoline service station/minimart currently in the process of fuel dispenser <br />upgrade. On April 12, 2002, under the direction of San Joaquin County Environmental Health <br />Department (EHD), twelve soil samples were collected from beneath the dispenser islands at the <br />subject site. The samples were analyzed by Associated Laboratories for benzene, toluene, <br />ethylbenzene, xylenes (BTEX) and oxygenated fuel additives by EPA Method 8260 and for total <br />petroleum hydrocarbons as gasoline (TPHg) by EPA Method 8015M. Methyl tert butyl ether (MTBE) <br />and Tert butyl alcohol (TBA) were detected at low levels in dispenser soil samples #11 and #12. No <br />other oxygenates, TPHg or BTEX were detected in any sample. Sample locations are shown on <br />Figure 2. Analytical results are summarized in Tablel. <br />Based on the analytical results, EHD filed an Unauthorized Release Report and has required further <br />investigation of the extent of contamination. Ground Zero submitted the Workplan for Soil <br />Excavation and Sampling to EHD on May 7, 2002. The Workplan proposed limited excavation of <br />contaminated soil in the vicinity of dispenser samples #11/#12 and confirmation soil sampling. <br />Fieldwork <br />Fieldwork took place on May 15, 2002.
