(Horizon) has prepared this letter report documenting the results of soil sampling at the subject site located in San Joaquin County as shown on Figure 1. The San Joaquin County Environmental Health Department (SJCEHD) required soil sampling as part of a dispenser pan upgrade project at the site. The upgrade project was performed by Walton Engineering, Inc. from West Sacramento. The station is located on the corner East Fremont Street and North E Street. The station building and other site features, current and former, are shown on Figure 2. Soil Sampling Soil sampling activities were performed by Horizon on March 5, 2003 in accordance with Horizon Field Methods and Procedures (Attachment A). The station was undergoing dispenser pan upgrade construction at the time of soil sampling. The product lines were disconnected and the dispensers had been removed prior to soil sampling. Soil samples were collected from beneath the removed dispensers D-1 and D-2 as directed by the SJEHD inspector. The soil samples were collected from hand auger borings with a hammer sampler at the locations shown on Figure 2. Soil samples were recovered from native sandy silt at a depth of approximately 5 feet below surface grade (bsg). No groundwater was encountered in the hand auger bore holes. The soil samples were submitted, under chain-of-custody documentation, to Kiff Analytical (Kiff), a California-certified analytical laboratory (ELAP No. 2236) located in Davis, California. The samples were analyzed for total petroleum hydrocarbons as total petroleum hydrocarbons as gasoline (TPHg), the volatile aromatic compounds benzene, toluene, ethylbenzene and total xylenes (13TEX), and the fuel oxygenates methyl-t-butyl ether (MTBE), diisopropyl ether (DIPE), ethyl-t-butyl (ETBE), tert-amyl methyl ether (TAME) and tert-butanol (TBA) by EPA Method 826013. Soil analytical results are summarized in Table 1.
