The location of the site is illustrated in Figure 1 -Location Map. A plan of the site is depicted in Figure 2 - Site Plan. Field activities at the site were performed in accordance with guidelines for investigation of underground storage tank(UST) sites established by the San Joaquin County Public Health Services - Environmental Health Division (PHS-EHD) and the Central Valley Regional Water Quality Control Board (CVRWQCB). 2.0. BACKGROUND 2.1. SITE LOCATION The site is located in a business/residential area of low topographic relief in Stockton, California. The site consists of one L-shaped building along Harding Way and base-rock covered parking at the rear of the building. The site is presently occupied by a dry cleaning business, a real estate office and a sign company. 2.2. UST REMOVAL Eight underground storage tanks (USTs) were removed from the site by Falcon Energy Associates (FEA) in January 1991. It is our understanding that the tanks contained stoddard solvents used in dry cleaning processes. Tanks Nos. 1 through 7 were removed from a common excavation along the southern portion of the property (tank pit No.1). Tank No. 8 was removed from beneath the sidewalk along Van Buren Street (tank pit No.2). Analysis of soil samples collected from tank pit No.I indicated an unauthorized release of petroleum hydrocarbons, while petroleum hydrocarbons were not detected in the samples collected from tank pit No. 2.
