' : ' -:,: - - _ Lz'C ' ENVIRONMENTAL MANAGEMENT CONSULTANTS SITE BACKGROUND - GEOLOGY . The site is located at an elevation of approximately 395 feet above MSL, and the topography slopes slightly to the south (see Figure 1). The site Is located in the southern portion of the Great Valley geomorphlc province. The Great .Valley Is a north-south-trending valley approximately 400 miles long by 50 miles wide, the southern portion of which is referred to as the San Joaquin Valley. The surface of the San Joaquin Valley Is underlc~in by Unconsolidated, Quaternary alluvial sediments. The alluvial sediments are underlain by older, predominantly lake bed deposits. These deposits lie unconformably on Miocene-Pliocene marine sediments, which extend to a crystalline basement at a depth of approximately' 30j300 fbg (California Division of Mines and Geology, 1965, Geologic Map of California, Bakersfield Sheet)i The Quaternary deposits form a homocline dipping gently to the north-northwest. The alluvium consists of silty sands and fine-grained to coarse-grained sands, with Intervals of finer grained sandy silts and clay. The deposits are alluvium consisting of poorly Indurated and dissected fan and lake bottom deposits. Surface soils are classified by the Soils Conse.rvation Services as Kimberllna - Urban Land - Cajon Complex and are characterized as 35 percent Kimberlina fine, sandy loam with moderate permeability; 30 percent Urban land with Impervious surfaces and altered fills; and 20 percent Cajon loamy sand with high permeability. HYDROGEOLOGY Surface water and groundwater in the San Joaquin Valley are derived predominantly from the Sierra Nevada to the east and are transported by five major rivers, the southernmost being the Kern River. The subject site Is located approximately 2 miles south of the Kern River. The depth to the regional unconfined aquifer is estimated to be In excess of lEVI fbg at the site, and the groundwater gradient Is anticipated to be to the south-southwest, toward the ancient Kern Lake bed (Kern County Water Agency (KCWA), 1998, 1997 Report on Water Conditions, Improvement District No~ 4, February 1, 1998). Perched groundwater at depths as shallow as 20 feet Is known to be present less than 1 mile to the east of the site, along the abandoned course of the Kern River, but Is not known to extend to the site (KCWA, 1998, 1995 Water Supply Report, January 1998). HOLGUIN, Mr. Phli-Holland ~ Yum Yum ShopPing Center ~ FAHAN February 26, 1999 - Page 3 ~ & ASSC~IATES, INC. ENVIRONMENTAL MANAGEMENT CONSULTANTS - SITE EVALUATION-METHODS - To conduct an LDI, three soil borings (B-1 through B-3) were drilled using a:hollow stem auger drill rig to a depth of 25 fbg in the areas of the former USTs and dispensers based uPon photographs of the former service station provided to HFA by the current property owner (see Figure 2 for the soil boring locations). SOIL INVESTIGATION AND SAMPLING RESULTS Prior to conducting the Current assessment, underground utilities such as water, electricity, and sewer were mapped by Underground Service Alert of Northern'California; HFA performed, the drilling and sampling on January 27, 19991 using a hollow-stem auger drill rig operated by Melton Drilling Company of Bakersfield, California. Soils encountered during drilling Included silt to well-graded sand and minor Intervals of silt (see Attachment 1 for the logs of exploratory borings and Attachment 2 for the soil boring and sampling procedures). Groundwater was not encountered during drilling. Soil samples were collected at 5-foot Intervals, and the soil samples collected from depths of 15 and 25 fbg were submitted .to HFA Environmental Laboratories, a California state-certified laborafory, for analysis. The six soil samples were analyzed for TPH as gasoline using EPA Method 8015 (M) and BTEX and MTBE using EPA Method 8020. Adsorbed-phase TPH as gasoline, BTEX, and MTBE concentrations were not detected In the soil samples collected from soil borings B-1 through B-3 (see Figure 2, Table 1 - Summary Of Soil Sample Analytical Results, and Attachment 3 for the laboratory reporf). CONCLUSIONS 1. Adsorbed-phase gasoline hydrocarbon concentrations were not detected In any of soil samples collected from the three soil borings drilled by HFA at the site. 2. Based on the findings of this soil assessment, the BFDESD will likely not require any additional soil Investigation activities and will likely consider the site for closure. hiT HOLGUIN Mr: Phil Holland FAHAN Yum Yum Shopping Center February 26, Page 4 ENVII~ONMENTAL MANAGEMENT CONSULTANTS , - Holguin, Fahon & Associates, Inc., trusts that you will find this Leak Detection Investigation Report to your satisfaction.

SOIL BORING AND SAMPLING PROCEDURES SOIL BORING AND SAMPLING PROCEDURES SITING Soil borings were positioned as noted In the report. TRUCK-MOUNTED DRILLING AND SOIL SAMPLING PROCEDURES Each soil boring was manually drilled for the first 5 feet to establish that the area was clear of subsurface struCtures. The soil borings were drilled with 8-inch-OD, hollow-stem augers to the depths noted in the report. During the drilling process, soil cuttings were continuously monitored in conformance with the monitoring procedures, and data was recorded on logs of exploratory borings by a state of California registered geologist. Soil samples were collected with a California-modified, split-spoon sampler at intervals consistent with the wOrk plan, unless a change in lithology was. noted, in which case an additional sample was collected. The sampler was outfitted with 2.5-inch by 6-inch stainless steel or brass sleeves. When the sample was withdrawn, the ends of the sleeve were covered with aluminlum foil or TeflonTM tape followed by plastic caps. Sample preservation, handling, and transportation procedures were consistent with HFA's QA/QC procedures. SOIL BORING MONITORING PROCEDURES Cuttings from soil borings were continuously classified according to the Unified Soil Classification System (USCS) and logged by a state of California registered geologist. Specific geologic and hydrologic information that was collected included stratigraphy (i.e., layer thickness, unit correlation, aquifer thickness, depth to groundwater, and confining units, if any), relative permeability, observed porosity, plasticity, moisture content, soil type, structure, size, and other features that could affect contaminant transport. Specific geologic and hydrologic information that was obtained during soil boring construction includes the following: · Stratigraphlc characteristics: thickness, correlation of units, extent (horizontal and vertical) of aquifers and confining units, If any; · Observed porosity; · Volatile organic content; · Particle-size distribution; · Moisture content; · Plasticity; · Strength; · Mineral composition; · Depth to groundwater; · Soil type, structure, size; and · Distribution of soil type. ~ ~ _ Soil B(~L~..g and Sampling Procedures Page 2 The data was recorded on Individual logs of exploratory borings, including observations regarding the types and quantities of waste materials encountered and any PID readings. This data was recorded on a standardized log sheet.In the Field Log Book. Specific information that was recorded Is listed In Table 1, below. TABLE 1.

The typed log of exploratory boring is on a form Identical to that used In the field log book. Each log of exploratory boring includes a graphic log in which a'symbol for each USCS soil group Is included for each soil Interval. ~ ~ ' Soil B and Sampling Procedures Page 3 DATA REDUCTION The data.'complled from the soil borings has been summarized and analyzed. A narrative summary of the soil characteristics was also presented. The logs of exploratory borings were checked for the following Information: · Correlation of stratigraphic units among soil borings; · Identification of zones of potentially high hydraulic conductivity; · Identification of the confining formation/layer; · Indication of unusual/unpredicted geologic features (fault zones, fracture traces, facies changes, solution channels, buried stream deposits, cross-cutting structures, plnchout zones, etc.); and · Continuity of petrographic features such as sorting, grain-size distribution, cementation, etc. Soil boring locations were plotted on a properly scaled map. The purpose of each soil boring/plezometer/monltoring well/pit/soil sample is Indicated on the map. Depending on the results of this analysis, the soil stratigraphy of the site Is presented In a scaled stratlgraphlc column (if soil stratigraphy is laterally homogeneous) or, more likely, in a scaled cross section or a fence diagram (if soil is laterally heterogeneous). Specific features that may Impact contaminant migration (e.g., fault zones or impermeable layers) are discussed in narrative form and supplemented with graphical presentations as deemed appropriate. DECONTAMINATION PROCEDURES Prior to each Sampling episode, the sampling equipment was decontaminated using a non-phOsphate soap and water wash, a tap water rinse, and two deionized water rinses. The drill string was decontaminated with a steam cleaner between each soil boring. WASTE MANAGEMENT AND DISPOSAL The cuttings from the soil borings were stored In 55-gallon, Department of Transportation-approved drums. Each drum was labeled with the date on which the waste was generated and the numbers of the soil borings from which the waste was withd~awn. The drums were stored at the site of generation until sample analyses were obtained. Sample analyses and an inventory of drums were then given to the client, who coordinated proper disposal of the soil, according to Regional Water Quality Control Board requirements. ~ FAHAN ~ & A~qOCIATE~, INC.
