Work Plan for Additional Well Installation - December 2000 <br /> FRANKLYN COLE PROPERTY (Reich's Grocery) <br /> 7505 West Linne Road, Tracy, California <br /> 1.0. INTRODUCTION <br /> At the request of Mr. Franklyn Cole,Advanced GeoEnvironmental, Inc. (AGE) has prepared the <br /> enclosed work plan for 7505 West Linne Road in Tracy, California(the site). The work plan details <br /> procedures for the installation of additional ground water monitoring wells at the site. The site <br /> setting is illustrated in Figure 1. Structures and well locations are illustrated in Figure 2. <br /> This plan was prepared to assess the methyl tertiary butyl ether (MTBE) impacted ground water. <br /> The site history and a description of previous work performed was presented in the Corrective <br /> Action Plan. A summary of soil remediation at the site was presented in Quarterly Report- June <br /> 1998 dated 15 September 1998 and other quarterly reports prepared by AGE. <br /> 2.0. SITE LOCATION AND BACKGROUND <br /> The site is located at the northwest corner of the intersection of Chrisman Road and Linne Road in <br /> a flat rural/agricultural area southeast of Tracy, California, in San Joaquin County. Jefferson School <br /> is located catacorner across the intersection, southeast of the site. <br /> 2.1. UNDERGROUND STORAGE TANK REMOVAL <br /> Two 1,500-gallon USTs, piping and dispensers were removed from the property in October 1993. <br /> Soil samples collected from beneath the dispenser at a depth of six feet contained total petroleum <br /> hydrocarbons quantified as gasoline (TPH-g) and volatile aromatics - benzene, toluene, ethyl <br /> benzene and xylenes (BTEX) were detected at concentrations as high as 48,000 milligram per <br /> kilogram (mg/kg). <br /> 2.2. SITE ASSESSMENT AND REMEDIATION <br /> In August 1994 two borings (B 1 and 132) were drilled in the area of the former fuel dispenser island. <br /> TPH-g was detected at concentrations as high as 13,000 mg/kg and hydrocarbons were encountered <br /> to depths of 35 feet below surface grade (bsg). <br /> On 22 February 1995,two additional borings(B3 and 134) were drilled north and south of the former <br /> fuel dispenser island. Low concentrations of volatile aromatics were detected in one sample from <br /> boring B4. Results of the site assessment indicated that impacted soil is present only in the area of <br /> the former dispenser island. <br />
