Soil samples will be placed in mason jars to approximately <br /> 50% capacity, shaken, and let stand for 15 minutes. At this time, a <br /> standard head space reading will be collected; <br /> 6. o Soil samples for analysis will be collected in brass tubes and sealed with <br /> end caps having a teflon liner separating the soil from the caps. The <br /> sealed tubes will be placed in a cooler with blue ice and transported to a <br /> California certified laboratory under Chain of Custody procedures on a daily <br /> basis; <br /> Analysis will be run on selected soil samples for all constituents using EPA <br /> methods��0 end 8015 modified; � (��r �_ ;�,� t , �� ( <br /> V �J� <br /> L o Preparation of a written report summarizing the lateral and vertical extent <br /> of contamination, type and concentration, and source of the contamination. <br /> 1.3 SCHEDULE <br /> Thorne Environmental anticipates beginning work described in this work plan within one <br /> week upon approval by the SJHD. The soil borings should be completed within one and <br /> a half weeks of mobilization to the site. This time estimate is dependent upon the <br /> exact number of borings required, the availability of a qualified drilling rig, the <br /> occurrence of good weather, and other factors including client needs and site specific <br /> conditions. Upon completion of boring advancement, a written report will be submitted <br /> to De Rollo Mazda. The written report will include; <br /> o Description of area geology; C <br /> ` o Site plan showing locations of borings; 1 <br /> o Copy of boring logs; <br /> o Summaries of laboratory analysis; <br /> O Copies of laboratory results; <br /> o Interpretation of data regarding vertical and lateral extent of contamination, <br /> concentration of contaminations as well as the source of the contamination; <br /> o Recommendations regarding contaminated remediation or disposal. <br /> 2.0 BACKGROUND <br /> De Rollo Mazda's former facility is located at Grant and Miner Avenues in the City of <br /> Stockton, San Joaquin County, California, as shown on Figure 1. <br /> 2 <br />
