Phase II Site Assessment Report Roberts Metals 1803 South Stockton Street, Lodi, California 1.0. INTRODUCTION At the request of Mr. Bill Maxwell of Maxwell Properties,Advanced GeoEnvironmental,Inc. (AGE) has prepared the enclosed Phase II Site Assessment Report for the property at 1803 South Stockton Street, Lodi, California(the site). The location of the site is illustrated on Figure I. Major features on the site and soil probe boring locations are illustrated on Figure 2. The work was performed to assess for possible environmental concerns associated with the property. This investigation was performed in accordance with guidelines of the San Joaquin County Public Health Services - Environmental Health Division (PHS-EHD) and of the Central Valley Regional Water Quality Control Board for the investigation of underground storage tank (UST) sites. Background information is summarized in the AGE work plan titled Phase II Site Assessment Work Plan, dated 31 January 2001. The scope of work included advancing five soil probe borings, collection and analysis of soil samples and abandonment of the soil borings. 2.0. PROCEDURES On 08 February 2001, five soil probe borings (P1 through P5) were advanced at the site as part of the site assessment. The field work was conducted as outlined in the AGE work plan. Soilprobe borings P 1 through P5 were advanced utilizing atruck-mounted Geoprobe 5400 equipped with 1.125-inch diameter probe rods using "direct push" technology. Each soil probe boring was advanced vertically to a depth of 15 feet bsg. The soil probe borings were sampled at discreet five-foot intervals using a 1.125" Geoprobe soil sampling assembly loaded with four six-inch brass sleeves. Upon sample retrieval, the ends of the second sleeve were covered with Teflon sheets, capped and sealed with tape. Each preserved sample was logged on a chain-of-custody form, placed in a chilled container and transported to McCampbell Analytical Inc. (MAI), a California Department of Health Services (DHS)-certified laboratory. The samples collected from 5-feet bsg in each boring were analyzed for total recoverable petroleum hydrocarbons (TRPH) and halogenated volatile organic compounds (HVOCs) in accordance with EPA methods 418.1 and 8010, respectively. Prior to sample collection, Geoprobe soil sampling equipment was thoroughly rinsed with,clean water after being washed with a solution of Alconox. Geoprobe rods were thoroughly cleaned prior to boring advancement. Advanced GeoEnvironmental,Inc.
