1.0 INTRODUCTION In accordance with ICF Kaiser Engineers' (ICF KEs') Work Plan of March 9, 1994 and our Addendum to the Work Plan of June 9, 1994, we have performed a soils and ' groundwater investigation to assess subsurface environmental conditions at the former Union Ice facility, located at 425 North Union Street, Stockton, California. This report begins with a ' summary of historical investigation and remediation efforts at the site, and then presents the results of our recent investigation. ' 2.4 BACKGROUND OF SITE AND PREVIOUS INVESTIGATIONS ' The former Union Ice facility is located at 425 North Union Street, Stockton, ' California. The site is situated north of Lindsey Street, east of the Union Pacific Rail Lines, south of a vacant lot and west of Union Street (Figure 1) Union Ice owned and operated an ice manufacturing plant on the site for over 100 years In 1989, Arctic Ice purchased the ' facility from Union Ice. storage tanks designated Tanks #1 through #4, Four single-wall steel undergroundg g g � were located on the site (Figure 2). Tanks #1 and #2 were 10,000-gallon diesel fuel tanks ' Tank #3 was a 500-gallon tank, which likely contained fuel oil prior to its end of use in late 1940's. Tank #4 was a 250-gallon waste oil tank for used motor and compressor oils In ' September of 1989, all of the tanks and associated piping were removed from the site by SEMCO under permit and direction of the San Joaquin County Environmental Health ' Division. Soil sampling from the bottom of each tank excavation was performed to evaluate past p g potential leakage/over filling of the tanks. The soil samples were analyzed for total petroleum hydrocarbons as gasoline (TPH-G), total extractable petroleum hydrocarbons (TPH-E), oil and grease, benzene, toluene, ethylbenzene, and total xylenes (BTEX), chlorinated ' hydrocarbons, metals, and ethylene dibromide. Analyses of the sample collected beneath Tank #3 detected 12,000 mg/kg motor oil. Analyses of the sample collected beneath the northern portion of the product line of Tanks #1 and #2 detected 78 mg/kg diesel. Soil samples collected from beneath Tanks #1, #2, and #4 were non-detect, although visual
