I I I CALIFORNIA SHEET METAL FACILITY January 1993 Page 1 I.O INTRODUCTION John McCauley has authorized PIWAREA ENGINEERING INC. (PIWAREA) to prepare this Site Contamination Workplan for Preliminary Site Assessment at the California Sheet Metal site located at 601 Eureka Street, Bakersfield, CA 93305. The Bakersfield City Fire Department Hazardous Materials Division is the lead regulatory agency. This Work Plan is for additional assessment activity at the Eureka Street facility. 1.1 PURPOSE The site assessment described in this Workplan has the following objectives: Further assess the lateral and vertical extent of on-site and off-site vadose zone contamination involving gasoline, and the gasoline constituents volatile aromatic, benzene, toluene, ethyl benzene, and xylene (BTEX). 1.2 SCOPE OF WORK The scope of services described in the Workplan include: Locating underground utilities using California Sheet Metal as-built drawings (if available) as well as Under- ground Service Alert (U.S.A.); Advancing two soil borings, one to the northwest and the remaining boringto the southeast of the existing boring cluster. The two borings will be advanced to a minimum depth of ten feet of unimpacted soil below a depth of twenty-five feet. Steam cleaning of all drilling and sampling equipment prior to and between each boring to avoid cross- contamination; Collecting soil samples at depths to be evaluated in the field. Initially, samples will be collected at approximately five foot intervals beginning at ten feet and continuing until total depth. The samples will be collected using a standard California split-spoon sampler .equipped with brass tubes, steam cleaned prior to use. These samples will be field screened and selected samples will be chosen for chemical analysis; I I I I I I I I I I I I I I I I I ! CALIFORNIA SHEET METAL FACILITY January 1993 Page 2 Field Screening will be accomplished using a photo- ionizing detector equipped with a 10.0er lamp. Soil samples will be placed in mason jars to approximately 50% capacity, shaken', and let stand for approximately 15 minutes. A standard headspace reading will be collected at this time; Soil samples collected for chemical analysis will be collected in brass tubes and sealed with teflon liners, end caps and tape. The sealed tubes will be placed in a cooler with blue-ice and transported to a DHS certified laboratory under chain-of-custody procedures; Analysis of selected soil samples for fuel hydrocarbons as gasoline and gasoline constituent volatile aromatics using DOHS Luft Method (purge and trap for gasoline) and EPA Method 8020, respectively; * Prepare field boring logs; Prepare a written preliminary investigation and evaluation report summarizing the results of the investigation with conclusions and recommendations. The report will be reviewed by a California Registered Geologist or civil Engineer. 1.3 SCHEDULE PIWAREA anticipates beginning work described herein within one week upon approval from the City and authorization to proceed from John McCauley. The soil borings can be drilled and sampled in approximately one working day. The analytical data will be reported within three weeks and the report will be completed within one week after receipt of the analytical results. 2.0 BACKGROUND The California Sheet Metal facility is located at 601 Eureka Street, Bakersfield, California as shown on Exhibit 1. FACILITY DESCRIPTION The facility as shown is not to scale, see Exhibit 2. The facility was used for fueling equipment. Previously located at the site was one 550 gallon gasoline underground storage tank and dispenser. I I I I I I I I I I I I I I I I I I I CALIFORNIA SHEET METAL FACILITY January 1993 Page 3 2.2 PROJECT HISTORY On or about December 17, 1991, an underground fuel tank (gasoline) was removed from the above referenced property location. Soil samples were collected from beneath the dispenser area. These samples were analyzed for total petroleum hydrocarbons (TPH) and volatile aromatic (BTXE). Gasoline constituents were detected beneath the tank (Exhibit 3). The analytical results indicated concentration in excess of state and county guidelines. On or about March 19, 1992, WILSON & ASSOCIATES, INC. (W&A) completed a total of six borings to assess the vertical and lateral extent of sub-surface contamination. A report dated September 2, 1992 was prepared by W&A for the six borings and is attached as Exhibit 3. The report recommended that two additional borings be completed to further assess the lateral extent of any contamination. John McCauley contracted PIWAREA to prepare this Workplan and implement a Site Characterization Study. 3.0 WORKPLAN PIWAREA proposes to assess and define the lateral and vertical extent of the contamination of the soil by completing two additional borings to the northwest and southeast of the former tank location. 3.1 SOIL BORING DEPTHS AND LOCATIONS Two soil borings will be drilled to a depth of approximately forty feet. Soil samples will be collected at five foot intervals beginning at ten feet and continuing until ten feet of unimpacted soil is encountered below a depth of twenty- five. The proposed locations are shown on Exhibit 4. The locations have been chosen to provide lateral definition in the vadose zone. B-7 will be placed to the northwest of the existing boring cluster and B-8 will be located in the alley to the southeast of the existing boring cluster. These borings will further assess the lateral extent of contamination. I I I I I I I I I I I I I I I I I I CALIFORNIA SHEET METAL FACILITY January 1993 Page 4 4.0 METHODS The following sections will describe in detail the methods to be employed in implementing this Workplan. 4.1 BORING METHODS The borings will be advanced using a Mobile Drill B-53 rig, or equivalent, with a six inch or larger hollow stem continuous flight auger in accordance with ASTM Method D 1452-80 for soil investigations and sampling by auger borings. The augers will be steam cleaned prior to drilling each boring. The lithology and other pertinent data will be recorded on a field boring log in accordance with ASTM Method D 2488-84 for visual description and identification of soils. Cuttings and other spoil from the borings will be placed in appropriate D.O.T. approved 55-gallon drums until verified, with analytical results, whether or not the soil is contaminated. If the material is contaminated, a written plan will be submitted by the facility operator to the City for their approval before treatment and/or disposal occurs. Disposal will be the responsibility of the Facility Operator and should occur within 90 days of completion of drilling. The facility operator has contracted with PIWAREA to remove all cuttings, etc. from the facility. PIWAREA intends to sent the soil to a recycler. Back filling of any soil boring or part thereof, will occur by pouring a bentonite cement mixture into the boring. 4.2 SOIL SAMPLING Soil samples will be collected through the auger in 2-inch brass sleeves driven in a split-spoon sampler by a 140 pound hammer with a 30-inch drop in accordance with ASTM Methods D1586-84 for split barrel sampling of soil and D1587-83 for thin-walled tube sampling of soils. The brass sleeves and sampler will be steam cleaned prior to each use. The blow counts, recovery, and lithology will be recorded on the field logs. Lithology will be described in accordance with ASTM procedure D2488-84 (Standard Practice for Description and Identification of Soils). One brass sleeve with soil from each interval will be capped, sealed, labeled in accordance with EPA protocols, recorded on a chain of .custody form, placed in a cooler at four degrees centigrade or less, and transported to a California Certified Laboratory with the chain of custody for the specified analysis. I I I I I I I I I I I I I I I I I I I CALIFORNIA SHEET METAL FACILITY January 1993 Page 5 4.3 SOIL ANALYSIS The soil samples will be analyzed by B.C. Laboratories, a California State Certified Laboratory, in accordance with State guidelines and EPA protocols. The samples will be analyzed for fuel hydrocarbons, as gasoline, and the gasoline constituents volatile aromatics using the DOHS Luft Method (purge and trap for gasoline) and EPA Method 8020, respectively. 4.4 FIELD SCREENING OF SOIL SAMPLES Soil samples will be collected using three six-inch brass tubes installed inside a split-spoon sampler. The middle sample tube will be immediately capped and stored in an iced cooler upon collection. The bottom tube will be used for lithologic description, and the top tube will be used for field screening. The material from the top tube will be placed in mason jars to approximately 50 percent capacity, shaken, and stored for a period of 15 minutes. A standard headspace reading will be collected at this time and noted on the boring log. 5.0 QUALITY ASSURANCE PLAN This section describes field and analYtical quality-assurance procedures to be followed during the investigation. 5.1 SAMPLE COLLECTION AND HANDLING PROTOCOL Proper sample collection and handling are essential to assure quality of data obtained from a sample. Each sample therefore, will be collected in a brass tube, preserved correctly for the intended analysis and stored for no longer than the permissible holding time prior to analysis. Protocol to be applied in this project is described in section 4. 5.2 SAMPLE IDENTIFICATION AND CHAIN OF CUSTODY PROTOCOL Sample identification and Chain of Custody procedures are designed to assure sample quality and to document sample possession from the time it is collected to the time of its ultimate disposal. The container for each sample submitted for analysis will have a label affixed with the identifying number or the number will be inscribed directly on the container if feasible. The analytical laboratory will assign I I I I I I I I I I I I I I I I I I CALIFORNIA SHEET METAL FACILITY January 1993 Page 6 a separate sample number to that sample for internal sample coordination and identification. A description of the sample including the sample number and other pertinent information regarding its collection and/or significance will be written in field notes and/or a boring log being prepared by the site engineer. These field documents will be kept in a permanent project file. All samples will be analyzed by a State certified laboratory for the analysis requested. A properly completed Chain of Custody Form will be submitted to the analytical laboratory along with the samples. The laboratory assigned number will be properly entered on the form. A quality control officer at the lab will verify integrity of the samples submitted, proper sample volume correctness of containers issued, and properly executed Chain of Custody Form. Pertinent information will be entered into a log book kept by the laboratory. 5.3 ANALYTICAL QUALITY ASSURANCE In addition to routine calibration of analytical instruments with standards and blanks, the analyst is required to run duplicates and spikes on ten percent of analysis to assure an added measure of reliability and precision. Accuracy is verified through the following: 1. U.S. EPA and State certification of results; 2. Participation in inter-laboratory round robin program; "Blind" samples are submitted for analysis by the quality control office on a weekly basis. These are prepared from the National Bureau of Standards specification of EPA reference standards; 4. Verification of results with an alternative method. 6.0 SITE SAFETY PLAN Appendix A contains a Site Safety Plan which complies with Worker Right to Know Regulations and CAC Title 26. APPENDIX A SITE SAFETY PLAN I I I I I I I I I I I I i I I I I CALIFORNIA SHEET METAL FACILITY January 1993 Page 7 INTRODUCTION A Site Safety Plan (SSP) has been designed to address safety provisions needed during the site soil assessment/remediation. Its purpose is to provide established procedures to protect all on-site personnel from direct skin contact, inhalation, or ingestion of potentially hazardous materials that may be encountered at the site. The SSP establishes personnel responsibilities, personal protective equipment standards, decontamination procedures, and emergency action plans. PIWAREA seeks to enter property described above for the purpose of conducting a site assessment consisting of up to four borings to evaluate the extent of soil impaction. Soil samples will be collected at five-foot intervals during exploratory drilling using a California modified split-spoon sampler through a hollow-stem auger. All possible efforts will be made to collect undisturbed samples. Each sample to be chemically analyzed will be collected in a brass sleeve, capped with lined plastic lids, sealed with tape, and placed on ice in a cooler immediately. All Chain of Custody protocol will be followed. Drilling equipment will be brought to the site and operated by a subcontractor: Soils Engineering, Inc. 4700 District Blvd. Bakersfield, CA 93309 C-57 License #253192 The SSP described means for protecting all on-site personnel from deleterious contamination or personal injury while conducting on-site activities, as described below, will meet all requirements promulgated by the California Department of Health Services. SITE BACKGROUND; This property is a fueling facility located on Eureka Street, Bakersfield, California. The facility contained one 550 gallon gasoline tank, and associated dispensers. I I I I I ! I I I I I I I I I I I I CALIFORNIA SHEET METAL FACILITY January 1993 Page 8 RESPONSIBILITY OF KEY PERSONNEL; Ail personnel on-site will have assigned responsibilities. Mr. John R. Wilson of PIWAREA, will serve as Project Manager and On-Site Engineer. He will also serve as Site Safety Officer (SSO). As SSO, Mr. Wilson will assure that on-site personnel have received a copy of the SSP. Personnel will be required to document their full understanding of the SSP before admission to the site. Compliance with the SSP will be monitored at all times by the SSO. The SSO will appropriate personal protective equipment, listed below, and will conduct a training session to assure that all are aware of safe work practices. In the training session, personnel will be made aware of hazards at the site and will utilize the Material Safety Data Sheets for information on compounds to be encountered. Mr. John Wilson will also be responsible for keeping field notes, collecting and securing samples, and assuring sample integrity by adherence to Chain of Custody protocol. On-site employees will take reasonable precautions to avoid unforseen hazards. After documenting understanding of the SSP, each on-site employee will be responsible for strict adherence to all points contained herein. Any deviation observed will be reported to the SSO and corrected. On-site employees are held responsible to perform only those tasks for which they believe they are qualified for. Provisions in this SSP are mandatory and personnel associated with on-site activities will adhere strictly hereto. JOB HAZARD ANALYSIS Hazards likely to be encountered on-site include those commonly encountered when operating any mechanical equipment, such as the danger of falling objects or moving machinery. Simple precautions will reduce or eliminate risks associated with operating such equipment. A drilling contractor has been employed to deliver and operate all drilling equipment. Qualified personnel only will have any contact with this equipment. All on-site personnel, including the drilling contractor and his employees, are required to wear hard hats when in close proximity to drilling equipment. Latex gloves will be worn by persons collecting or handling samples to prevent exposure to contaminants. Gloves I I I I I i I I I I I I ! I I I ! I CALIFORNIA SHEET METAL FACILITY January 1993 Page 9 will be changed between samples, and used ones discarded, to avoid cross-contamination. Proper respiratory equipment will be 'worn if vapor contamination levels on-site exceed action levels as determined using PID. Action levels requiring respiratory apparatus will be 5 ppm, in the breathing space. Furthermore, no on-site smoking, open flame, or sparks will be permitted in order to prevent accidental ignition. RISK ASSESSMENT SUMMARY: Exposure to chemicals anticipated on-site include gasoline, diesel, benzene, toluene, and xylene (BTX). These chemicals represent a hazard because they are moderately to extremely toxic and most are highly flammable. Threshold Limit Values (TLV's), Short Term Exposure Limits (STEL's), and Toxicity Levels (LD50, oral-rat), all in mg/kg (ppm), are listed below: Compound TVL STEL Toxicity Gasoline 200 300 Benzene 10 25 4894 Toluene 100 150 5000 Xylene 100 150 4300 Benzene is considered an extreme cancer hazard. EXPOSURE MONITORING PLAN: A Photo-Ionization Detector (PID) will be used to monitor vapor concentrations around the site. Should concentrations exceed TLV's, protective measures will be taken. Passive dosimeter badges will be placed in downwind locations if PID readings indicate high levels of volatile organics in the breathing space. PERSONAL PROTECTIVE EQUIPMENT: Personnel on-site will have access to respirators with organic vapor cartridges. Replacement cartridges will be available on-site as needed. When handling samples, the on-site personnel will wear latex gloves. Hard hats will be worn by all personnel on-site when in proximity of drilling equipment. I I i I I i I I I I ! I I I i I I I CALIFORNIA SHEET METAL FACILITY January 1993 Page 10 WORK ZONES AND SECURITY MEASURES: Access to the site will be restricted to authorized personnel. A set of cones, placecards, or wide yellow tape, surrounding the site will define the perimeter. The Project Manager will be responsible for site security. DECONTAMINATION MEASURES: Avoidance of contamination whenever possible is the best method for protection. Common sense dictates that on-site personnel avoid sitting, leaning, or placing equipment on possibly contaminated soil. Ail personnel will be advised to wash their hands, neck and face with soap and water before taking a break or leaving the. site. Respirators will be washed with soap and water following each day's use. Drilling and sampling equipment used will be decontaminated by steam-cleaning. Sampling equipment will be decontaminated before each sample is taken and drilling equipment will be decontaminated before each boring is commenced. GENERAL SAFE WORK PRACTICES: Drillers and other on-site personnel will be briefed each day in "tailgate" meeting as to the day's goals and equipment to be used. Anticipated contaminants and emergency procedures will be reviewed. Appropriate personal protective equipment will be put on and verified correct by SSO, including respirator fit. Drilling and sampling equipment will be steam-cleaned before being brought on-site. Split-spoon sampling equipment will be steam-cleaned before each use. Augers will be steam-cleaned between borings. The On-Site Engineer will oversee operations and log boring in consultation with drillers. The Sample Coordinator will assure that proper protocol is used at all times in collecting and handling samples. TRAINING REQUIREMENTS: The SSO will conduct a pre-site training session which will include all points of MSDS forms, contaminant properties, warning signs, health hazard data, risk from exposure, and I I I i I I I I I I I i I i I I I I I CALIFORNIA SHEET METAL FACILITY January 1993 Page 11 emergency first aid. Ail chemicals to be covered and the SSO will assure that everyone fully understands site hazards. MEDICAL SURVEILLANCE PROGRAM: According to CFR 29, 1910.120, paragraph (f), employees who wear respirators 30 days or more during one year or who have been exposed to hazardous substances or health hazards above established permissible exposure limits are required to be monitored medically. RECORD KEEPING: Documentation will be kept on personnel exposed to contaminant hazards on the job site according to OSHA regulations. These will include documentation that employees have received training on the SSP, respiratory protection, MSDS forms, and all emergency procedures. These will be reviewed during the pre-site training meeting. Exposure records on each job will be kept for 30 years to meet requirements. Included will be names and social security number of employees, medical evaluations, on-the-job logs from entry to exit, first aid administered, visits on-site by outside persons, and personal air monitoring record. CONTINGENCY PLANS: In the event of accident, injury, or other emergency, the Project Director, Senior Project Manager, or other person will notify appropriate government agencies or individuals as follows: Bakersfield City Fire Department Hazardous Materials Division 2130 "G" Street Bakersfield, CA 93301 (805) 326-3979 2.

(W&A) at the above referenced site. The purpose of the characterization was to assess the lateral and vertical extent of soil impacted by gasoline hydrocarbons associated with a former 550 gallon underground gasoline storage tank removed from the property on December 17, 1991 by CALPI, INC. of Bakersfield, California. A concentration of Total Purgeable Hydrocarbons (TPH) as gasoline was detected at 810 mg/kg, and 10,000 mg/kg at depths of two and six feet beneath the former tank. Toluene was detected at 170 mg/kg, and 275 mg/kg at depths of two and six feet beneath the tank. See attached laboratory results. The concentrations of TPH as gasoline and the gasoline constituent volatile aromatics detected in the samples from beneath the tank are in excess of Regional Water Quality Control Board (RWQCB) recommended guidelines, and resulted in the Lead Implementing Agency (LIA) which is the City of Bakersfield Fire Department - Hazardous Materials Division requesting that an initial site characterization consisting of soil borings and laboratory analysis of soil samples be performed to assess the vertical and lateral extent of gasoline impacted soil in the vicinity of the former underground gasoline storage tank. The fuel dispenser was located directly above the tank, and therefore no additional soil samples were required at this location. The scope of work for this project developed in conjunction with Mr. Joe Dunwoody of the City of Bakersfield Fire Department - Hazardous Materials Division. In addition, remedial action alternatives are presented. Work performed to date includes the following: Development of site health and safety, and technical work plans. Drilling and sampling of six exploratory soil borings to a maximum depth of 90 feet below surface grade. Laboratory analysis of nineteen selected soil samples for Total Purgeable Hydrocarbons as gasoline, and the gasoline constituent volatile aromatics.

I :1 I I PRELIMINARY SITE CHARACTERIZATION CALIFORNIA SHEET METAL SEPTEMBER 1992 PAGE NO.2 1.1 Site Description The subject site is located on the south side of Eureka Street in the City of Bakersfield, Kern County, California. The site was used as a commercial "Sheet Metal Facility". The underground fuel tank was used to provide fuel for the service trucks. The site is situated within a developed urban and commercial area. Nearby properties are primarily commercial businesses along both sides of Eureka Street, and residential areas to the south. The overall site topography is essentially flat. 1.2 Background Based on a review of analytical results, a 550 gallon underground gasoline storage tank, and dispenser located directly above the tank were removed under City of Bakersfield Permit Number BP0031 from the above referenced property. Reportedly, no soil was removed from the site during removal of the tanks. Soil Samples were collected at depth of two and six feet from beneath the removed tanks. The samples from beneath the gasoline were analyzed for the presence of total purgeable hydrocarbons (TPH) s gasoline, and the gasoline constituent volatile aromatics (BTEX). Gasoline was detected at 810 mg/kg, and 1,000 mg/kg at depths of two and six feet beneath the former tank. Benzene was detected in the two samples at 4.4 mg/kg and 98 mg/kg at depths of two and six feet. Toluene was detected at 170 mg/kg, and 275 mg/kg at depths of two and six feet beneath the tank. Ethyl benzene was detected at 19 mg/kg, and 170 mg/kg at depths of two and six feet beneath the tank. The concentration of TPH as gasoline and the gasoline constituent volatile aromatics detected in the soil samples from beneath the tank are in excess of Regional Water Quality Control Board (RWQCB) recommended guidelines, and resulted in the Lead Implementing Agency (LIA) which is the City of Bakersfield Fire Department - Hazardous Materials Division requesting that an initial site characterization consisting of soil borings and laboratory analysis of soil samples be performed to assess the vertical and lateral extent of gasoline impacted soil in the vicinity of the former underground gasoline storage tank. The fuel dispenser was located directly above the tank, and therefore no additional soil samples were required at this location.

Below are the results of the site characterization. 2.0 METHODS OF INVESTIGATION 2.1 Drilling and Soil Samplin_q Prior to commencing field operations, a technical work plan was reviewed and approved by City of Bakersfield Fire Department - Hazardous Materials Division personnel. Underground Service Alert was notified 48 hours in advance of the site activities. Drilling commenced on March 19, 1992 using a CME~'" B-75 truck mounted drill rig, operated by Soils Engineering, Inc. of Bakersfield, California, and equipped with six 3/4-inch diameter hollow-stem augers. The augers were steam cleaned prior to use to minimize the possibility of cross-contamination. A total of six borings were drilled within this phase of soil characterization. One soil boring, B-1 was drilled through the approximate "center" of the tank excavation to a depth of ninety feet. A second soil boring, B-2, was drilled on the south edge of the tank excavation to a depth of thirty feet. A third soils boring, B-3, was drilled southeast of the tank excavation to a depth of forty feet. The fourth soil boring B-4, was drilled southwest of the tank excavation to a depth of forty feet. Boring number five, B-5, was drilled northwest of the tank excavation to a depth of forty feet. The sixth boring, B-6, was drilled northeast of the tank excavation to a depth of forty feet. Soil samples were collected at 5-foot intervals in each of the borings using a split-spoon sampler (ASTM D 3550 with shoe similar to ASTM D 1586) equipped with three 6-inch by 2.5-inch diameter stainless steel sleeves for soil retention. The soil samples were obtained by driving the sampler with a 140-pound hammer dropping 30 inches in accordance with ASTM D 1586. I I I I I i I I I I I I I I I I I I PRELIMINARY SITE CHARACTERIZATION CALIFORNIA SHEET METAL SEPTEMBER 1992 PAGE NO.4 The lowermost sleeve at each sample intervals was screened for total organic vapors with a photo-ionization detector (PID). Headspace vapor analysis was performed by first discarding a portion of the soil retained at one end of the sleeve to produce a headspace. The sleeve was then capped and the probe of the PID was inserted through a hole in the cap and into the headspace for~ analysis. The PID readings are recorded on the boring logs. The middle sample sleeve was immediately transferred to a glass jar, capped, security taped, labeled, and placed on ice for transportation to a California Department of Health Services (DOHS) certified laboratory. Strict chain of custody procedures were utilized for all samples collected to ensure sample integrity and to document sample possession from the time of collection to the final destination. Ail sampling equipment was washed with TSP (tri-sodium phosphate) cleanser, and rinsed with tap water and de-ionized water prior to sampling, between sample intervals, and between borings to minimize the possibility of cross-contamination. The drill auger was steam cleaned between borings, also to minimize the possibility of cross-contamination. Contaminated drill cuttings and soil sample spoils were stored in D.O.T. approved 55-gallon drums, sealed, and left on-site pending appropriate disposal. After drilling, the borings were backfilled with a 2 sack cement, sand, and bentonite clay grout to seal the abandoned boreholes. 2.2 Laboratory Analysis Nineteen samples were selected for analysis based on: a) observations and greatest PID readings of odorous soil, b) observations and PID readings of the first encountered sampling locations containing apparently uncontaminated soils, which would serve to define the lateral and vertical extent of contamination, and c) requirements that the two lowermost samples of each boring which detects gasoline hydrocarbons be submitted for analysis. The nineteen samples were analyzed at BC Laboratories for benzene, toluene, ethyl benzene and total xylenes (BTEX) by the USEPA Test Method 8020, and total purgeable hydrocarbons (TPH) as gasoline by the DOHS LUFT Manual Method. I I I I I I I I I I I I I I I I I I PRELIMINARY SITE CHARACTERIZATION CALIFORNIA SHEET METAL SEPTEMBER 1992 PAGE NO.5 3.0 RESULTS OF ENVIRONMENTAL ASSESSMENT 3.1 gub-Soil Conditions Regional Geology: The site is located in the southern part of the Great Valley. The Great Valley is a north-south trending valley, approximately 400 miles long by 50 miles wide. Surface and groundwater in the San Joaquin Valley is derived predominantly from the Sierra Nevada mountain range to the east, and is transported by five major rivers, the southern most being the Kern River. The subject site is located approximately three miles south of the Kern River. Site Soils: Soil deposits in the study area include alluvial sediments of the Kern River Formation, which dip to the southwest. The deposits are alluvium consisting of poorly graded fan deposits. The depth to the regional unconfined aquifer is approximately 200 feet below surface grade beneath the site with the direction of groundwater flow to the south (Kern County Water Agency, Improvement District No. 4, 1991 Report on Water Conditions, February, 1992).. The nearest known occurrence of perched groundwater is 2 miles to the southwest at a depth of 20 feet in the abandoned Kern River channel to the ancient Kern Lake Bed (Kern County Water Agency, 1991 Water Supply Report, May, 1992). No perched groundwater is known to exist beneath the subject site. 3.2 Subsurface Conditions Subsurface material encountered during drilling included artificial fill in the former tank pit underlain by alluvium to the total depth of each boring. The artificial fill was encountered in the upper portion of boring B-1 from the surface to approximately 10 feet. The fill consisted of a medium brown, silty sand (SM). 3.3 ~y~rogeolog~ Groundwater was not encountered in any of the borings drilled during this project. The project to the regional unconfined aquifer is approximately 200 feet below surface grade beneath the site with the direction of groundwater flow to the south (Kern County Water Agency, Improvement District No. 4, 1992 Report on Water Conditions, February, 1992). The nearest known of perched groundwater is 2 miles to the southwest at a depth of 20 feet in the abandoned Kern River channel to the ancient Kern Lake Bed (Kern I I I I I '1 I I I I I I I I I I PRELIMINARY SITE CHARACTERIZATION CALIFORNIA SHEET METAL SEPTEMBER 1992 PAGE NO.6 County Water Agency, 1991 Water Supply Report, May, 1992). No perched groundwater is known to exist beneath the subject site. 3.4 Soil Vapor Monitoring Soil samples collected during drilling were monitored with a photo-ionization detector (PID) to evaluate organic vapor concentrations. The PID was calibrated with an isobutylene standard of 100 per million (ppm) and contained an 11.8 electron volt (eV) lamp, capable of detecting benzene (9.25 eV). Boring Logs presents the PID readings as they were recorded in the field. 3.5 Laboratory Analytical Results Boring B-1 was advanced through the center of the former 550 gallon tank where (TPH) as gasoline were detected at 6,000 mg/kg at 5 feet and 15 feet, at 3,100 mg/kg at 30 feet, at 3,000 mg/kg at 45 feet and 18,000 mg/kg at 60 feet. TPH as gasoline was not detected at 75 feet, 80, 85 and 90 feet. TPH wad detected in Boring B-2 at 12,000 mg/kg at 15 feet and at 400 mg/kg at 30 feet. TPH as gasoline was detected in Boring B-3 at 30,000 mg/kg at 25 feet. TPH as gasoline was detected in Boring B-5 at 7,000 mg/kg at a depth of 40 feet. TPH as gasoline was not detected at 30 and 40 feet in B-4, at 15 feet in B-5 and at depths of 20, 30 and 40 feet in B-6. The gasoline constituent volatile aromatic benzene was detected in eight of the nineteen samples analyzed. Benzene was detected in; Boring B-1 at 5 mg/kg at 45 feet, 110 mg/kg at 60 feet and 0.084 mg/kg at 90 feet, Boring B-2 at 1,000 mg/kg at 15 feet and 0.2 mg/kg at 30 feet, Boring B-3 at 400 mg/kg at 30 feet, Boring B-5 at 0.011 mg/kg at 35 feet and 42 mg/kg at 40 feet. Benzene was not detected in B-1 at depths of 5, 15, 30, 75 80 and 85 feet, B-2 at depths of 30 feet, and 40 feet, B-6 at depths of 20, 30 and 40 feet. Toluene was detected in .thirteen of the nineteen samples. Toluene was detected in; Boring B-1 at 210 mg/kg at 5 feet, 390 mg/kg at 15 feet, 86 mg/kg at 30 feet, 160 mg/kg at 45 feet, 1,300 mg/kg at 60 feet, 0.047 mg/kg at 85 feet, 0.16 mg/kg at 90 feet, Boring B-2 at 1,500 mg/kg at 15 feet, 1.2 mg/kg at 30 feet, Boring B-3 at 3,400 mg/kg at 25 feet, Boring B-5 at 0.017 mg/kg at 15 feet, 540 mg/kg at 40 feet, Boring B-6 at 0.008 mg/kg at 40 feet. Toluene was not detected in Boring B-1 at 75 and 80 feet, B-4 at 30 and 40 feet, B-6 at 20 and 30 feet. I I I I I I I I I I I I I I I I I PRELIMINARY SITE CHARACTERIZATION CALIFORNIA SHEET METAL SEPTEMBER 1992 PAGE NO. 7 Ethyl benzene was detected in ten of the nineteen samples analyzed. Ethyl benzene was detected in; Boring B-1 at 50 mg/kg at 5 feet, 170 mg/kg at 15 feet, 71 mg/kg at 30 feet,~75 mg/kg at 45 feet, 300 mg/kg at 60 feet and 0.049 mg/kg at 90 feet, Boring B-2 at 340 mg/kg at 15 feet, 4.7 mg/kg at 30 feet, Boring B-3 at 800 mg/kg at 35 feet, Boring B-5 at 160 mg/kg at 40 feet. Etl]yl benzene was not detected in Boring B-1 at 75, 80 and 85 feet, Boring B-4 at 30 and 40 feet, B-5 at 15 feet, B-6 at 20, 30 and 40 feet. Due to the presence of "gasoline" in the soil, selected samples were analyzed for Lead. Lead was detected in B-1 at 5 feet at 39 mg/kg (TTLC) and 2.7 mg/1 (STLC), at 30 feet at 4.5 mg/kg (TTLC) at 85 feet at 4.5 mg/kg, at B-2 at 30 feet at 3.9 mg/kg, at B-6 at 20 feet at 3.6 mg/kg and at 40 feet at 8.5 mg/kg. Regional Water Quality Control Board recommended guidelines for gasoline, and the gasoline constituent volatile aromatics, benzene, toluene, recommended and total xylenes have been calculated using the LUFT methodology by multiplying the most stringent current federal or state water quality standards by a factor of 1,000 to account for attenuation due to site-specific parameters including vertical separation to 'ground water, soil lithology, fractures in subsurfaces, annual average precipitation, and any direct conduits to ground water. The limits are 1,000 mg/kg for TPH as gasoline, 1.0 mg/kg for benzene and toluene, and 50 mg/kg for ethyl benzene and total xylenes. 4.0 CONCLUSIONS The data obtained from the field operations suggest that soil impacted with gasoline hydrocarbons, and the gasoline constituent volatile aromatics at concentrations in excess of RWQCB recommended guidelines exists at the subject site in the area directly beneath the former 550 gallon underground gasoline storage tank to a depth of 60-75 feet, and laterally of approximately 35 feet. Tile estimated volume of soil with concentrations of gasoline hydrocarbons in excess of 1,000 mg/kg, and volatile aromatics in excess a their respective recommended guidelines is 6,000 cubic yards. I I I I I I I I '1 I I I I I I I I I PRELIMINARY SITE CHARACTERIZATION CALIFORNIA SHEET METAL SEPTEMBER 1992 PAGE NO.8 4.1 Remedial Action Alternatives At least four options for remediation of the soil are applicable to the site 1) excavation and transportation of soil to an approved landfill or recycling facility, 2) in-situ vapor extraction, 3) excavation and uncontrolled aeration, and 4) no action. In the first action, impacted soil would be excavated and transported to a suitable disposal site or recycling firm. Due to the depth of the contaminated soil we believe that the existing means of excavation would not be suitable for this site. The next option is to treat the soil through in-situ vapor extraction. Wells are drilled into the impacted soil. The hydrocarbon vapors are extraction and treated as a unit such as a thermal oxidizer. We believe that three wells would effectively extract the gasoline hydrocarbons, and the time frame for successful treatment would be approximately six to nine months. The cost for installing the wells and below ground manifolding would be approximately $32,000.00. The monthly cost rental of an extraction unit will be approximately $8,500.00/month, or $42,5000 for five months, including the cost of electricity, and/or supplemental fuel. Verification, soil sampling and system abandonment would be approximately $17,300. Management fees including Work Plans, regulatory liaison, supervision, reports, etc. will be approximately $10,000. The overall cost is estimated to be $101,800. However, we believe that additional borings will be necessary to further define the lateral extent of the contamination. The third option is to excavate the soil and "aerate" on-site. Again due to the depth of the contamination we believe that excavation of the soil is not acceptable. The fourth option is to leave the site "as-is" and allow natural in-situ biodegradation to occur. Due to the high concentrations of gasoline and the gasoline constituent volatile aromatic we believe that there is a "risk" of leaking hydrocarbons to groundwater, which is at a depth of approximately 200 feet. Long term monitoring of the hydrocarbons may be required at additional costs. I I I I I I I I I I I ,i I I I I i'I PRELIMINARY SITE CHARACTERIZATION CALIFORNIA SHEET METAL SEPTEMBER 1992 PAGE NO.9 5.0 RECOMMENDATIONS WILSON AND ASSOCIATES, INC. would recommend that two additional borings be completed in order to assess the ~lateral extent of the contamination. One boring would be located southwest of Boring B-3, and another boring would be located northwest of Boring B-5. At the completion of the laboratory analysis. W&A would prepare a Work Plan for implementation of a vapor extraction system. 6.0 CLOSURE This report has been prepared for the exclusive use of the John McCauley as it pertains to the location of the former gasoline tank at 601 Eureka Street, Bakersfield, California. The conclusions and recommendations rendered are opinions based on information obtained within the scope of work authorized by the client. This report should not be regarded as a guarantee that no further contamination, beyond that which may have been detected within the scope of this study, is present on or beneath the site. If additional information regarding the possible presence or past use of hazardous materials at the site becomes available, then the need for further field investigation should be re-evaluated. Similarly, if suspected contamination is encountered during earthwork or construction activities, a qualified engineer or geologist should be on-site to monitor the soils and collect samples for laboratory analysis.
