SUMMARY OF SOIL CONTAMINATION INVESTIGATIONS <br /> and <br /> SOIL REMEDIATION PLAN <br /> for <br /> Roy's Towing <br /> 3570 East Miner Avenue <br /> Stockton, California <br /> 1.0 Introduction <br /> Ground Zero Analysis, Inc. (Ground Zero) has completed several phases of environmental <br /> investigation at the subject site on behalf of Roy and Norma Knoll. The location of the site is <br /> shown on Figure 1. <br /> 2_0 Purpose <br /> The purpose of this document is to summarize the results of investigations undertaken to <br /> determine the nature and extent of soil contamination at the subject site; to present and evaluate <br /> remedial alternatives for soil remediation; and to propose a remediation plan. <br /> 3_0 Background <br /> The subject site is a towing service yard located in Stockton, California. The property is <br /> bounded by East Miner Avenue to the north, Highway 99 to the east, Highway 4 to the south, <br /> and a small business property to the west. One structure, used for office space and parts storage <br /> is currently located on the property. Prior to Right of Way (ROW) acquisition, the parcel <br /> owned and occupied by Roy's Towing was larger than at present and included a second structure <br /> used as a mechanics' shop/workshop. This shop was located east of the existing structure. The <br /> eastern portion of the site, approximately 50-60 feet wide and 430 feet long, was acquired by <br /> the California Department of Transportation (CalTrans) for Highway 99 improvements. A site <br /> plan is depicted on Figure 2. <br /> On February 1, 1988 California Department of Health Services (DHS) personnel inspected the <br /> property and observed apparent soil staining, primarily in the vicinity of the warehouse/office <br /> building and the workshop. Samples were collected from surface soil near the two structures <br /> as well as from a small sump inside the warehouse building and from two storage containers. <br /> Laboratory analysis reported that some of the surface soil samples contained elevated <br /> concentrations of petroleum hydrocarbons and/or lead. The sample collected from the sump <br /> contained elevated lead concentrations and detectable levels.of petroleum hydrocarbons. <br /> MAreperW\summay 1 <br />
