LEVINE•FRICKE <br /> September 15, 1993 LF 2655. 00 <br /> RESULTS OF SOIL INVESTIGATION BY LEVINE*FRICKE <br /> AND RESULTS OF 1990 UNDERGROUND STORAGE TANK REMOVAL <br /> 950 INDUSTRIAL WAY, STOCKTON, CALIFORNIA <br /> INTRODUCTION <br /> This report summarizes the results of sampling conducted by <br /> Levine•Fricke in January 1993 at 950 Industrial Way ("the <br /> Site") , located in Stockton, California (Figure 1) . <br /> The sampling was conducted in accordance with the November 24, <br /> 1992 work plan, submitted to the San Joaquin County Public <br /> Health Services Environmental Health Division (SJCEHD) , and <br /> under SJCEHD permit number 93-0013 (January 5, 1993 ; <br /> Attachment 1) . <br /> As requested by Ms. Diane M. Hinson at a January 5, 1993 <br /> meeting, data related to the removal of the underground <br /> waste-acetone storage tank (UST) is also presented in this <br /> report. This data includes analytical results for soil <br />. samples collected by a previous consultant in 1989, following <br /> the removal of the waste-acetone UST. <br /> LEVINE•FRICKE SOIL INVESTIGATION <br /> On January 28 , 1993 , five soil samples were collected by <br /> Levine•Fricke personnel, three from soil borings and two at <br /> surface soil locations (see Figure 2) . <br /> Three soil borings were completed approximately 5 feet below <br /> ground surface (bgs) using a hand auger. Soil samples <br /> (SS-1--5.5, SS-2-5, and SS-3-5) were collected from the bottoms <br /> of the borings, using a slide hammer sampling tool containing <br /> a brass tube. After sample collection, the brass tubes were <br /> capped with aluminum foil and plastic caps, labeled, and <br /> placed in a chilled cooler with ice. The sampler and the hand <br /> auger were washed with Alconox detergent and drinking water, <br /> and were rinsed with distilled water between borings. <br /> Using a hand trowel, samples SS--4-0.5 and SS-5-0. 5 were <br /> collected from surface soil locations, at an approximate depth <br /> of 0. 5 feet bgs, and placed in glass jars with plastic caps. <br /> The trowel was wiped clean between the two sampling locations. <br /> Each boring was filled with cement grout after the samples <br /> were collected. Michael Infurna of SJCEHD was present to <br /> inspect the grouting procedure. <br /> 2655\2655-SI.RPT w[k 1 <br />
