1.0 INTRODUCTION <br /> 1 This quarterly monitoring report was prepared by American Geological Services, Inc. for <br /> Western Refrigerating and Cold Storage Company. As part of the ongoing quarterly <br /> ' monitoring and site investigation program, this report details all field activities performed <br /> on October 15, 1997 at the Tracy Cold Storage site and the results of these activities. The <br /> following sections describe the methodology employed and the results obtained during <br /> ' this sampling event. Historical ground water analytical data is also provided for each of <br /> the previous sampling events. <br /> 1 -1.1 Site Description <br /> ' The Tracy Cold Storage site is located at 24500 S. MacArthur Road in Tracy, California <br /> (Figure 1). The property includes approximately eight acres of land which is utilized as a <br /> commercial cold storage facility for agricultural products. The site is bounded on three <br /> ' sides by undeveloped agricultural land. The northern boundary of the property is shared <br /> with the Southern Pacific Railroad. No residences are located within 1,000 feet of the <br /> site. <br /> Approximately 44,000 square feet of cold storage space, various maintenance buildings, <br /> '. and an office are located on the property. Water is supplied by two on-site wells. A <br /> septic system is located on-site. <br /> ' 1.2 Site Background <br /> ' Remcor, Inc. of Pittsburgh, Pennsylvania, conducted an environmental assessment in <br /> May, 1994 to determine the current environmental condition of the site. Remcor's report, <br /> dated July 21, 1994, indicated that the potential for soil or ground water contamination <br /> ' existed on the property. Of primary concern was a former underground gasoline storage <br /> tank that had been removed in the 1970's. No information regarding tank condition, <br /> possible soil or ground water contamination, or subsequent investigations was provided, <br /> ' however, it was reported that the tank was removed because it was known to be leaking. <br /> On August 4 and 5, 1994, Remcor supervised the drilling of seven soil borings. Three of <br /> ' the borings were completed as ground water monitoring wells. Both soil and ground <br /> water samples were collected for analysis of suspected or potential contaminants. Based <br /> upon the information obtained during this investigation, it was determined that an impact <br /> American Geological Services, Inc. <br /> CA95DE-029 <br /> ' i <br />
