San Joaquin Street <br /> Stockton, California 95201 <br /> Attention Mr. Michael J. Infu ma Jr., R.E.H.S. N0 ; <br /> TRANSAMTAL <br /> ANALYTICAL DATA AND CONCLUSIONS r N6T lAf <br /> 1044 SOUTH AURORA STREET <br /> STOCKTON, CALIFORNIA <br /> Dear Mr. Infurna: <br /> As requested, this letter presents a summary of investigation work performed and analytical <br /> data collected by PFS Environmental Inc (PES) for Sims-LMC Recyclers (LMC) during their <br /> pre-acquisition assessment of the property located at 1044 South Aurora in Stockton. This <br /> work was performed under permit number 92-3454 issued by the San Joaquin County Public <br /> Health Services. <br /> OVERVIEW OF INVESTIGATION AND FINDINGS <br /> PFS conducted the site investigation on October 13, 1992 which consisted of angering nine <br /> shallow soil borings to a maximum depth of 3.0 feet below ground surface. The locations of <br /> the borings are presented on the attached site plan. Soil samples were collected at :lepths of <br /> 2.5 and 3.0 feet in each of the borings. These depths represent the first encountered fine <br /> grained soil under a layer of compacted gravel fill with some evidence of asphaltic material. <br /> This fill material was apparently imported to improve the surface of the site for traffic and <br /> �torage purposes. Upon collection of soil samples, the gravel surfacing materials were <br /> replaced within the shallow holes to the ground surface resulting in (1) no change to the near <br /> surface soil conditions and (2) no possibility of providing a potential conduit for contaminants <br /> to impact the subsurface. <br /> Soil samples were collected and composited in the laboratory to prepare three samples for <br /> chemical analysis. The compositing sequence and the results of the chemical analysis are <br /> presented on the attached Tables i and 2 for organic and inorganic contaminant indicators <br /> respectively. The laboratory reports, prepared by Coast-to-Coast Analytical Services are also <br /> 1682 Novato Boulevard • Suite 100 • Novato, California 94947 • (415) 899-1600 • FAX (415) 899-1601 <br />
