One 500-gallon storage tank for <br /> regular. gasoline was located at the site. According to Mr. <br /> Luther Thompson of Marlowe Properties, the tank was removed in <br /> January 1988. <br /> ® Samples of native soil were collected from locations below the <br /> former tank. Results of soil analyses indicated that there has <br /> been contamination of the soil below the former tank. In <br /> response to the detected soil contamination, the tank cavity was <br /> further excavated to an average depth of approximately 17 feet, <br /> the safe operating limit of the equipment used. Laboratory <br /> results of soil samples collected from approximately 17-feet <br /> below grade indicate that a significant amount of contamination <br /> exists. <br /> This Work Plan describes further work proposed at this site, <br /> including delineation of the vertical and lateral extent of soil <br /> contamination and an evaluation of the degree to which ground- <br /> water contamination may have occurred at the site. A series of <br /> --- <br /> tasks is presented that is designed to provide necessary <br /> his-site.- <br /> ---information- for assessment-of contamination--at__t <br />
