61 <br />tank T-4, the soil was a reddish brown sandy clay from which a slight gasoline odor was <br />noted. In sampling location T4-2 from beneath former tank T-4 the soil was a reddish <br />brown to an olive green sandy clay from which a gasoline/diesel odor was noted. <br />Observations of the bottom of the excavation indicated that this discolored soil was <br />limited to an area one to two feet deep and two to three feet across. <br />In addition, at the request of the SJCPHS soil samples were obtained from beneath the <br />three former product dispensers (identified as D-1 through D-3) and the product supply <br />line trench (identified as PL -1) (see Figure 2). At a depth of approximately three feet <br />the soil was noted to change from a dark brown sandy clay to a reddish brown sandy <br />clay to clayey sand. This reddish brown soil was believed to represent the native soil <br />and at the request of the SJCPHS samples were obtained from the top of this reddish <br />brown soil. Sampling at these locations was performed by using a backhoe to <br />excavate to the proper depth and then bringing up a volume of relatively undisturbed <br />soil for examination and sampling. <br />Product dispenser D-1 was located on the southeast end of the pump island (farthest <br />from the excavation) and the sample from this location was identified as D-1. Product <br />dispenser D-2 was located in the center of the pump island and the sample from this <br />location was identified as D-2. Product dispenser D-3 was located on the northwest <br />end of the pump island (nearest the excavation) and the sample from this location was <br />identified as D-3. A sample was also obtained from the center of the product supply <br />line trench adjacent to dispenser D-2 and was identified as sample PL -1. <br />The soil from beneath former fuel dispensers D-1, D-2 and D-3 was a reddish brown <br />sandy clay to clayey sand. At sample location D-1 a slight gasoline/diesel odor was <br />noted, at location D-2 a gasoline/diesel odor was noted, and at location D-3 no <br />=J1 <br />MMw:\24.2G1%USTAPT 126 -OCT -981 <br />
