MRODUCTION j <br /> At the request of Mr. Michael Hakeem of HAKEEM, ELLIS, SIMONELLI AND MARENGO, <br /> Advanced GeoEnvironmental,Ine.(AGE)has prepared this Preliminary Site Assessment Report as i <br /> required by the San Joaquin County Public Health Services-Environmental Health Division(PHS- � <br /> EHD) for soil assessment at the former Delta Paper Company facility at 401 S. Lincoln Ave., <br /> Stockton, California (Figure 1). This report describes the procedures used for collecting and <br /> preserving-`soil and groundwater samples, analyses of selected soil and groundwater samples, <br /> findings,and recommendations. <br /> The purpose of the investigation was to assess the potential presence of petroleum hydrocarbon <br /> compounds in soil/groundwater resulting from former site operations as identified during a Phase <br /> I site assessment of the property.Areas of potential environmental concern to be investigated include <br /> an outdoor cru.5bi ng area with visible hydrocarbon staining on concrete within a secondary <br /> enclosure,two former fuel tank sites and two sites with disturbed pavinglasphalt patched concrete. <br /> Assessment was for total petroleum hydrocarbons"all"and chlorinated hydrocarbons. <br /> 2.4. SCOPE OF WORK <br /> Advanced GeoEnvironmental, Inc. (AGE) proposed the collection of soil samples to assess for <br /> petroleum hydrocarbon-unpacted soil or chlorinated hydrocarbon-impacted soil in areas of potential <br /> environmental concern at the site. The scope of work consisted of the tasks outlined in the AGE- <br /> prepared Preliminary Site Assessment Work Plan dated 21 July 1999,and primarily was to advance <br /> soil borings, collect soil samples for laboratory analysis in areas identified as having potential <br /> environmental concerns_ Additionally, one groundwater sample from boxing 81 and one liquid <br /> sample from within a discovered UST was collected and analyzed. Procedures for groundwater <br /> sampling and analysis are discussed in section 2.2. <br /> 2.1. SOIL SAMPLE COLLECTION AND ANALYSIS <br /> AGE advanced 4 soil probe borings at selected areas of potential environmental concern.The soil <br /> probe boring locations are shown on Figure 2. Three probe borings were attempted adjacent to the <br /> secondary enclosure for the crushing machine. The conditions were not conducive for direct-push <br /> techniques,so that boring was not completed. One soil probe boring was advanced adjacent to each <br /> of the two fbrnr er(?)fuel tanks,and two soil probe borings were advanced in an area of disturbed <br /> concrete and asphalt patched concrete. <br /> Advanced GeoEnvtroamental,Inc. <br /> r <br />
