The site is on the :5euthwestern corner of North Cherokee Lane and Elm <br /> Street in Lodi, as shown on the Site Vicinity Map (Plate P-1). The locations of the ground- <br /> water monitoring wells relative to site facilities are depicted on the Generalized Site Plan <br /> (Plate P-2). Previous work at the site by Applied GeoSystems is documented in the reports <br /> cited in +he attached References list., <br /> A geologist from Applied GeoSys±ems visited the site on December 14 and 15, 1989, to <br /> collect ground-water samples from the five monitoring wells for laboratory analysis. The <br /> depth to the groundwater surface was measured and the water was analyzed suhjectively <br /> in each monitoring well using proceciurt a outlined in the attached Field Procedures. The <br /> geologist noted no subjective evidence of hydrocarbon product. <br /> Grounc+ water from each monitoring well wat: purged and sampled as outlined in the Field <br /> Procedures. The field geologist initiated a Chain of Custody Record that accompc.nied the <br /> samples to the analytical. laboratory. A copy of that the Chain of Custody record is <br /> attached. The purge water fr,,,,n the wells was stared temporarily onsite in properly labeled, <br /> 55-gallon, 17-E steel drums, approved for that use by the Department of Transportation, <br /> pending ren doval by Ultramar. <br /> xqr r <br />
