1.0 INTRODUCTION This document is submitted as the Soil Assessment Report, for the McHenry Ave. Project located at 1303 First Street, Escalon, California hereafter referred to as the "subject property" or "site" (see Figure 1). The purpose of the soil assessment was to evaluate the recognized environmental conditions identified in the 1996 environmental investigation conducted by Kleinfelder Inc. for the purpose of providing sufficient information regarding the nature and extent of contamination to assist in making informed business decisions about the property. The scope of work for this project is outlined in the San Joaquin County Environmental Health Department (EHD) approved Work Plan for Soil Investigation Beneath Former UST's prepared by Ground Zero Inc. on 25 August 2008. 1.1 SITE DESCRIPTION The subject property consists of one parcel located at 1303 First Street, Escalon, San Joaquin County, California. The site is located within a rural residential and agricultural setting. The site is bounded by McHenry Ave. to the west, a vacant lot to the east, retail dive shop to the south, and First Street to the north. 1.2 SITE HISTORY The subject property was historically occupied by a gas station used for the retail of petroleum fuel. On 9 September 1986, under San Joaquin County EHD permit seven underground storage tanks used to store petroleum hydrocarbon fuels were removed from the property. Analytical data from the soil samples collected during tank removal activities were not submitted to EHD in an approved format. See Figure 2 for the approximate location of the former USTs. ht 1996 two borings (B-22 and B-24) were drill for the purpose of collecting soil samples as part of an environmental investigation conducted by the City of Escalon along the McHenry Ave / Hwy 120 corridor in preparation for a roadway realignment project. Soil samples collected from boring location B-24 indicated the presence of elevated petroleum hydrocarbons on site. See Figure 2 for a site map with boring locations. 12/22/2009 HANOVER ENVIRONMENTAL SERVICES, INC. 1 Soil Assessment Report McHenry Ave Project 1303 First Street, Escalon
