CONSTRUCTI( 1.0 INTRODUCTION This report presents the results of a site characterization to detennine the extent of tliesel fuel contamination of soil at the ARB Construction Yard at 1500 South Union Avenue, in Bakersfield, California (Plate 1). Groundwater Resources, Inc. (GRI) conducted the investigation. A vadose plume of fuel hydrocarbons with a diameter of approximately 55 feet to a depth of 60 feet was confirmed to exist beneath the tank excavations. Included with this report are the fmdings, an evaluation of the site, and some suggested remediation alternatives. 2.0 BACKGROUND On September 20 and 21, 1989 nine tanks were removed from the site. The tanks had been used to fuel the construction equipmeni·ãt thé-Ÿàid and contained either diesel, gasoline or waste oil. Please refer to the plot plan, Plate 2 for the tank locations. Soil samples taken during the excavation at depths of two feet and six feet below the bottom of the tanks indicated TPH (diesel) at a maximum concentration of 1190 ppm, gasoline at 8400 ppm, and benzene with a maximum of 20.9 ppm. Two waste oil tank locations were also tested for lead ( 19.3 mg/kg max.), TaX (nd), and oil and grease (62537 mg/kg max). These results were included in the tank closure report dated October 24, 1989. The purpose of this site characterization was to detennine the vertical and lateral extent of the hydrocarbon plume. A plan for this work was filed with your office in a letter dated December 14, 1989. In accordance with that plan, eight borings were drilled and samples of soil were collected on February 14 through 16, 1990. The samples were analyzed for BTXE using the DHS approved 8020 method, and TPH (diesel). Some of the samples were also tested for TPH (gasoline). 3.0 BORINGS AND SAMPLING PROCEDURES Eight borings were drilled as shown on the plot plan, plate 2. The borings were made with an eight inch diameter continuous flight hollow stem auger. Drilling was performed by Melton Drilling of Bakersfield, California, under supervision of a GRI geologist. The cores were taken at five foot intervals with a California split spoon sampler and described as they were collected. Logs of each boring are presented as plates three through ten. All samples were immediately sealed, labeled and placed on ice for transport to BC Laboratory. A chain of custody document (appendix B) was maintained from collection to delivery to the lab. All augers and downhole equipment were steam cleaned between borings and the sampling equipment was washed and double-rinsed to prevent cross contamination, in accordance with the sampling protocol in appendix C. 4.0 FINDINGS 4.1 Laboratory Analysis of Soil Samples The contours on the plot plan and on the cross sections (Plates 11 through 14) will show APRIL 3, 1990IPage 1 GROUNDWATER RESOURCES, INC. ~ .. , , A.R.D.

Contours drawn on the benzene results produce an essentially identical volume in shape, size and location to that of the TPH contours. Positive responses to the portable Pill meter used on site occurred from 35 feet to 60 feet in boring B1, and were supported by low level positives in the laboratory analyses. Similarly, low levels were found in B3 to a depth of 90 feet. In the most distant borings, B8 and B9, no substantial Pill readings were found, no odors were detected and no positive analytical results were obtained. Borings B-3, B- 8 and B-9 serve to establish the maximum lateral and vertical extent of the plume. --- 4.2 Geology and Hydrology As can be seen in the attached soil borings, the soil consists of fine to coarse-grained stream deposits. Silty fine sand is the dominant soil type. Clayey silt intervals occur generally between 30 and 50 feet, but these are not laterally extensive. No clear correlation can be seen between the soil type and hydrocarbon levels. No groundwater was encountered, nor were any low penneability horizons found which might retain perched water. According to the Kern County Water Agency (J.D. 4) Report for 1988, the depth to the uøœnfine<¥ aquifer is approximately 180 feet. The rapid decline in hydrocarbon levels in Boring B3 between 50 and 60 feet and the consistently low or non-detectable levels from 60 to 120 feet would indicate that the plume has not migrated very far below 60 feet. 5.0 REMEDIATION AL TERNA TIVES 5.1 No Action Due to the 100 ppm level of benzene found at 40 feet and the 7900 ppm TPH (gasoline) at 50 feet in boring B3, a no action option cannot be considered. 5.2 Excavation Excavation of the plume to a depth of 55 feet with the sides sloped a 45 degree angle will require the removal of approximately 20000 cubic yards of soil. The cost of such a massive undertaking is prohibitive, so this option also is not considered. 5.3 Vapor Extraction Vapor extraction will provide the most efficient and cost effective means of remedi- ating the contaminated soil. Extraction wells will reduce hydrocarbon levels in the plume to essentially the non-volatile components of the diesel fuel. With a high volume flow of fresh air through the plume, the diesel TPH will also oxidize and biodegrade to low levels, thereby reducing the toxicity and mobility of the remaining hydrocarbons. APRIL 3, 1990IPage 2 GROUNDWATER RESOURCES, INC. " :< . , A.R.D. CONSTRUCTION ~ No short tenn threat to air, soil, surface waters or to bioreceptors exists in the present state. However, a long tenn threat to groundwater does exist in that the liquid plume has apparently traveled to a depth of about 90 feet, or half the depth to the unconfined water table. No perched water was found from which a penneability barrier to protect the main aquifer could be inferred. Groundwater draining through the plume is very likely to carry with it dissolved hydrocarbons to the aquifer. ~. -. ....~....-.. _....~ -'~ ...., .,,....~=.. -' . -- 5.32 Well Configuration GRI recommends installation of four 4-inch diameter PVC cased vapor extraction wells. One of these is to be placed in the center of the plume, near boring B3, and the others in a triangular pattern around the center well (refer to the plot plan for the proposed well locations). The sandy soil texture and the lack of laterally extensive penneability barriers will allow for a radius of influence of a single well of more than 30 feet. Because of the low levels of hydrocarbons found at 90 feet and the substantial vapor concentrations (as indicated by the portable PID meter) at that depth, remediation should be extended to approximately 100 feet. The center well will have two zones of perforations, one near the maximum depth of the plume and one at the depth of the highest hydrocarbon concentrations, in the 30 to 60 foot range. The. twoz9Pÿ~~will.beJs.Qlf,1œçU:nmH1aç~pther with an intermediate level seal of bentonite in the casing-boring..annulus. With such a "dual zone" completion, the major portion of the plume can be extracted through the shallower set of perforations in a predominantly horizontal flow direction. Since most of the air flow will be between the perforations and the air "source" (the surface), remediation at depth will be reduced in effectiveness. The lower set of perforations will be properly positioned for remediation of the deeper portion of the plume. 5.33 System Operation A 25 cubic feet per minute pump rate is planned! This flow rate will produce an average soil gas flow velocity of 3.2 feet per day at the perimeter of the plume and a minimum rate of 2.4 feet per day at the perimeter equidistant from the lateral wells. Th~.p'lu~~_\y_i},L~~ fullY swept with.one fresh air volume per day, or 30 volumes per month. At this rate, tl.!~~~j~~~y...pL!Þ~ r~medi~~ll be accomplished in the first month. In the initial operation of the process, a plug will be installed in the center well inside the casing between the two perforation intervals to confine all extraction to the most severely contaminated portion of the plume. Very high concentrations of volatiles are expected in the first days or weeks after start-up, followed by a steady decline. Hydrocarbon levels_and air flow rates between the extraction wells and the surface equipment will be monitored closely. After the shallow zone hydrocarbon levels are reduced to non-detectable, the plug will be removed and extraction will then proceed through the - lower set of perforations for remediation of the deeper portion of the plum~This sequence will avoid drawing any of the most severely contaminated portion of the plume in a downward direction which would increase the volume of affected soil as well as reduce the contaminant to groundwater separation distance. APRIL 3, 1990IPage 3 GROUNDWATER RESOURCES, INC. ·" , . , A.R.D. CONSTRUCTION 5.34 Surface Facilities The expected high concentrations of hydrocarbon vapor in the extraction system in the early stages will require some fonn OÎztheIJn~",,2.&~~ The type of equipment to be used is not detennined at this time. This will depend upon cost, availability and source pennitting restrictions from the APCD. A pennit to operate from the APCD will require source testing of the system in a pilot operation mode after well construction. Within about one month after startup the hydrocarbon concentrations should be drastically reduced. At that time an evaluation will be done regarding the continuation of the thennal system versus switching to activated carbon for long tenn low level remediation. Monitoring will be done to comply with APCD pennitting requirements and to provide the data needed for daily operations and for timing of conflI'IIlation borings. 6.0 TANK EXCAVATIONS AND SOIL PILES The north-central tank excavation shown on the plot plan was lined with plastic and backfilled to stabilize the borings around the excavation and to provide a platfonn for the drilling of B3. The soil used was from the stockpiles left on the surface from the tank excavations. A portable PID meter was used to screen the soil for hydrocarbons. No contaminated soil was replaced into the excavation. The other two excavations remain open, and of the four soil stockpiles on the location, one is shown in the Preliminary Site Assessment (October 24, 1990) to have elevated hydrocarbon levels." The open excavations are to be backfilled and compacted using the clean stockpiled soil. A GR! Geologist will be on the location to screen the soil with a PID meter. . Qm'Am~na~~n segregated and re-covered pending remediation. At this point, the contaminated soil on the surface can be assessed as to the volume of soil and the hydrocarbon levels in it. When this infonnation is available, a plan for remediation of the soil on the surface can be submitted. ."' 7.0 WASTE OIL SAMPLING (SHOP AREA) Additional samples were collected from two waste oil tank locations at the shop area, shown on the plot plan. At the northeast corner of the shop building a sample was collected using a back hoe from a point about 8 feet below the bottom of the tank. A test of that sample for oil and grease (method 413.1) showed 44 ppm. This compares to tests in the preliminary assessment of 44 ppm at 6 feet and 36 ppm at 2 feet. (Maximum lead and TOX for this location were 11.3 ppm and ND respectively.) A shallow boring was drilled inside the shop to investigate the depth of contamination beyond the six foot depth in preliminary assessment. In the previous work, stained and contaminated gravely clay was found from the concrete pad to the 6 foot depth. At 2 feet and 6 feet below the base of the mechanic's pit oil and grease at 62537 and 61 ppm respectively were found. The clay was penetrated at about 10 feet and native sandy soil was encountered. A sampling attempt at 14 feet failed because the loose APRIL 3, 1990IPage 4 GROUNDWATER RESOURCES, INC. · , A.R.D. CONSTRUCTION dry sand ran out of the bottom of the sampler. A sample, was collected at 19 feet and it produced a 34 ppm oil and grease result (method 413.3). The preliminary assessment levels for lead at 2 and 6 feet, respectively were 42.6 and 8.96 ppm. TOX levels were ND for both. 8.0 LIMITATIONS The discussion and conclusions presented in this report are based on: - The test borings performed at the site. - The observations of field personnel. - The results of laboratory tests performed by BC Laboratories, Bakersfield, California. - Our understanding of the regulations of Kern County and the California Regional Water Quality Control Board. It is possible that variations in the soil or groundwater could exist beyond the points explored in this investigation. Also, changes in the hydrogeologic conditions found could occur at sometime in the future due to variations in rainfall, temperature, regional water usage, or other factors. The services provided by GR! have been conducted in a manner consistent with the levels of care and skill ordinarily exercised by professionals currently practicing under similar conditions in California. No other warranty, expressed of implied, is made. Respectfully Submitted, GROUNDWATER RESOURCES, INC. (GRI) A~þ<~~-/ the;; r~ Rex J. Young State Registered Geologist #720 Gary J.

CA 93301 Re:Site Characterization Workplan ARB, I nc . 1500 South Union Ave. Bakersfield, CA 93307 Dear Ms. Crumoler: On September 20. 1989. under Permit No~ A983-25, nine underground storage tanks were removed at the above referenced facility. The Preliminary Site Assessment Report was submitted on October 24. 1989. Groundwater Resoursas.. Inc. {GRI) has been retained to investigate potential SOl j contamination that was observed during the removal project. This facility was in operatlcn untll mld-1989 as the headquarters, storage and maintenanc8 locatlon for ARB, Inc. The property consisted of offiçes. mechanics shop areas. warehousing, vehicle and equlpment storage for the construction activities of the owner. The underground storage tanks consisted of motor vehicle fuels (gasoline ana diesel) and two waste oil disposal tanks. ARB, Inc. has relocated their operations to another facility in Bakersfield and the site at 1500 South Un10n Avenue currently is not in daily use. The tank removal activlties were in anticipation of placing the property on the market Tor sale. The preliminary assessment was conducted under the guidelines of UT-30, with ai 1 soil samples being analyzed by a State Certified Laboratory. BC Laboratories. Inc. of Bal<ersfield. The available inventory records of the underground tanks do not show any inventory discrepancies. Only one tank removed during the project indicated any physical leal~age through small holes in the tanl~ shell. It is believed that piping system problems have accounted for the indications of potent1al soil contamination identified in the remaining tank areas. MAILING ADDRESS: P.O. BOX 9383, BAKERSFIELD, CA 93389 LOS ANGELES (2] 3) 724-3 J 47 (805) 835-7700 r " Ms. Turonda crum~r 4IÞ Resource Management Agency Department of Environmental Health Services December 14, 1989 Page Two We will investigate the facility by using a planned approach, using the preliminary site assessment data and visual observations made during the removal project. The enclosed Plot Plan 2 indicates the locations of the former tank areas and we have selected soil boring locations based on an evaluation of laboratory results. In order to complete the proposed borings. we recommend that the excavated soil be screened on site using a photoionization detector and GRI Geologist. The excavated soil will be separated on site. Clean soi 1 wi 11 be used as additional bacl~fi 11 material for the existing excavations. Soil with detectable concentrations will be segregated and secured on site for future disposal or treatment. This wi 11 allow clean imported backfi 11 material to be used and compacted so that borings can be safely conducted. The current plan is to conduct a minimum of ten soil borings at this facility to properly conduct the Site Ch~zation. In order to advance the SOi 1 borings, a hollow-stem auger rig will be utilized, using a California Modified Split Spoon Sampler. This wi I 1 allow fer undisturbed SOl I samples to be obtained at intervals of every five feet. The complete definition of the vertical and riorlzont.al extent of any potent.ial so;1 ~ontamination will be 3ch -; e'/ed . During the site boring project, all borings will be logged, sampled at fi'/E 7~Ot int.er\/als ç"nd a"t. rnaJ:Jr 'lithological changes.

For your review, we have included in the appendix, a copy of the GRI Sampllng Protocol and Health and Safety Plan, which will be utilized on si~e during the project. The Health and Safety Plan will be tailored to this site and augmented by pre-work Tailgate Meetings for all personnel involved with this project.

Soil borings drilled by the hollow stem auger util1ze continuous flight ho'llow stem augers. 2. Augers, samplers and all downhole equipment are steam cleaned prior to use. In the field steam cleaning 1S done between borings to minimize the potential for cross-contaminätion. 3. A G.R.I. geologist observes the worK, visually lags the salls, and collects samples at appropriate intervals. 4. The Unified Soils Classification System is utilized to classify sails encountered. Additional gaolog1cal observations are noted as appropriate. 5. Soi'( samples destined for Jöboratory analysls are collected by a modified California Split Spoon. This sampler uses three, six lnch long, by two and one- half inch diameter (o.d.) tubes~ Various tubes can be utillzed to accommodate the type of analysis necessary: Brass All organlcs and general analyses (not to þe used for copper or Zlnc analysis) Stainless Steel All organ1cs and metals analyses for copper and zinc (not to be used for chrome or nicKel analyse~) Plastic All metals analyses (not to be used for organics) ~. . groundwater resources inc. WJï e TEST BORING PROCEDURES (Cont'd) 6. The tubes are cleaned and prepared in the G.R.I. laboratory. Tubes are scrubbed, inside and outside, with a brush and TSP, rinsed, dryad, and pacKed in clean containers with seals. Tubes are delivered to the drilling site in these closed containers to preserve the state of cleanliness. 7. After the sample(s) have been removed from the sampler, the sampler is completely disassembled and scrubbed in TSP and tap water. It is then rinsed in clean tapwater and reassembled with three clean tubes. 8. Dirty tubes are field washed in TSP solut.ion, rinsed with water, and reused. 9. The sampler is driven by a 140 pound hammer with a 30 inch free fall. Blow counts are recorded as number of blows per inch of drive. 10. The sampler is driven 18 inches at each sampling interval. The first (or lowest) tube is generally retained as the sample for analysis. The ot.her two tubes are retained for back-up or split samples. 11. A sand catcher is used in the sampler where loose soi Is are anticipated. This Wl I prevent. the soil from falling out of the sampler. 12. After retrieval, the sample is visually logged and immediately sealed with aluminum foil lined caps, 1 abel ed, and ch i "\ led. CI ean ice chests and chern; ca 1 ice ("blue ice") are used to keep the samples cold until delivered to the chemical laboratory. Teflon seals are also available for field samples. 13. Samples are delivered to the laboratory the same day they are taken, if physically possible. If the samples must be held until the next day, they are kept frozen in a secure freezer at the G.R.I. facility. 14. Sample control is maintained by a Chain of Custody form which accompanies the sample. The form documents the time, date, and responslble person during each step in the transportation process. , .í\ groundwater resources inc. ~ e e MONITORING WELL SAMPLING PROTOCOL II. Groundwater Sampling A. All equipment that is used in a monitorlng we1 I for purging, sampling, or depth measurement 1S decontaminated by steam cleaning or a TSP wash and rinse procedure prior to use and before re-us1ng when more than one sample 1S collected. B. Purge Volume Determination The fOllowing procedure is followed to determine the appropriate purging volume prlor to well sampllng. 1. The depth-to-water is measured by a clean, electric level indicator. Measurement datum is the top of well protector. 2. Depth to the bottom of the well is measured by a clean tape and plumb bob. If possible, this is compared to the we 11 construct ion log to determi ne inconsistencies, i.e. darnäged casing, sediment in casing, etc. 3. Water volume is calculated by using the total water depth and the ins'j de d i arnete r of the cas i ng . C. Well Purging and Sampling 1. Prior to sampling, a mlnimum of three to f1ve well volumes are purged from each well to ensure that water sampled is representative of the groundwater within the formation. 2. Measurements of H, conduct1vity and temperature are taken at frequent intervals dur1ng the purge. Stabilization of these values indicates that representative formation flulds are being removed from the we 11 . " . e e ./\ > groundwater resources inc. ." MONITORING WELL SAMPLING PROTOCOL (Cont'd) 3. In the event that the well is pumped dry, and alternate procedure will be followed. Once a well is pumped dry, the water that enters the well during recovery is, by definition, representative formation water. The well will, therefore, be pumped dry and allowed to recover to 80% or more of the original water 1 eve 1 . 4. Purge water is pumped directly into barrels on site until the proper method of disposal is determined. 5. Samples are pumped or poured from a bailer into sampling bottles prepared by a state certified laboratory contracted for the particular jOb and placed in refrigerated coolers for transport to the laboratory. 6. Samples are delivered by courier, directly to the lab on the same day of sampling, whenever practical. If next day delivery is necessary, the samples are kept refrigerated at 4 degrees C overnight and delivered to the laboratory the following morning. 7. Samples are accompanied by a Chain of CustOdy form which documents the time, date and responsible person during each step of the transp~rtation process. 8. The G.R.I. coded sample numbering system allows identification of sample and client to G.R.I., whi Ie not revealing the client to anyone else. e .r\ groundwater resources inc. ."

REMEDIATION REPORT ARB INC. 1.0 INTRODUCTION Since July 3, 1991, RESNA Industries Inc. (RESNA) has been actively remediating soil by vapor ;/ extraction at ARB Inc., 1500 South Union Avenue in Bakersfield, California. On January 5, 1993, 1- RESNA advanced one soil boring CB-3 to a depth of 50 feet to collect soil samples for analysis (see Plate 2 for boring location). The following report includes background data, field procedures, laboratory analysis results, conclusions and recommendations for the site. 2.0 BACKGROUND On September 20 and 21, 1989, nine underground storage tanks were removed from the site. The tanks had been used to fuel construction equipment at the yard and contained either diesel, gasoline or waste oil (see Plot Plan). Soil samples were collected beneath the tanks and gasoline and diesel constituents were reported in the soil. A site characterization was perfonned by RESNA to define the extent of the hydrocarbons in the soil. The eight soil borings defined the plume as extending to approximately 60 feet in depth anti approximately 15 feet radially from the tank locations (see Site Characterization Report dated April 3, 1990). RESNA proposed vapor extraction of the plume and a penn it to operate the vapor extraction system was granted by the Kern County Air Pollution Control District. Since the start of the vapor extraction process a number of soil borings have been advanced into the hydrocarbon plume area to assess the current level of contaminants in the soil. Table 1 presents cumulative analytical results from these soil borings and locations are shown on the Plot Plan. One of these borings (YEW -S) was converted into a vapor extraction well to facilitate the extraction process on February 1, 1992. The original center vapor extraction well was abandoned at the same time by filling it with cement. Analytical results from soil samples collected from boring CB-2 drilled on August 13, 1992 indicate significant reduction in hydrocarbon concentrations at this location. Analytical resul.t£·from boring CB 1 indicated further extraction was necessary in a silty zone at a depth of 40 feet........On the basis of these results, the vapor extraction well was modified with packers to concentrate extraction on the silty zones between 38 to 48 feet below grade on August 22, 1992. Hydrocarbon concentrations in the effluent airstream increased substantially after this modification. Since this change an additional 2,000 pounds of hydrocarbons have been extracted for a total over 11,000 pounds removed during remediation (see enclosed vapor extraction data graphs).

The remedial targets at this site are 10,000 ppm for TPH as diesel, 1,000 ppm for TPH as gasoline, 1 ppm for benzene, 50 ppm for toluene, 50 ppm for ethylbenzene, and 50 ppm for total xylene. Verbal approval was received from the Kern County Department Of Environmental Health Services to conduct a 50-foot confinnation boring to assess the current hydrocarbon concentrations beneath the site. The boring, CB-3, was drilled on January 5, 1993. 3.0 PROCEDURES The soil boring CB-3 was drilled with a Mobile B-53 drill rig equipped with 8-inch-diameter, hollow- stem augers. Auger flights and sampling equipment were steam-cleaned before use to minimize the possibility of downhill or crosshole contamination. Drilling was observed by a State of California Registered Geologist, and the earth materials in the borings were logged in accordance with the Unified Soil Classification System as drilling progressed. Soil samples were collected at 5-foot intervals with a California-modified, split-spoon sampler equipped with clean brass sleeves from a depth of 30 to 50 feet. Samples were be collected by advancing the auger to a point just above the sampling depth and driving the sampler into the native soil. The sampler was driven 18 inches with a standard 140-pound hammer repeatedly dropped 30 inches. The number of blows required to drive the sampler each successive 6-inch interval was counted and recorded to give an indication of soil consistency. RESNA INDUSTRIES INC. FEBRUARY 19. 1993/Page 2 ~ e e :,;: ,0 REMEDIATION REPORT ARB INC. Soil samples selected for possible chemical analysis were sealed quickly with Teflon tape and plastic caps. The samples were labeled and placed in iced storage for transport to the laboratory for analysis. Chain of Custody Records were initiated by the geologist and accompanied the samples to the laboratory. Copies of these records are attached. Soil samples were evaluated on-site with a photo ionization detector (PID), which measures hydrocar- bon concentrations in the ambient air or heads pace above the soil sample. Field instruments such as the PID can be used to evaluate relative concentrations of hydrocarbon vapor but not with the accuracy of laboratory analysis. PID-readings are presented on the Log of Boring CB-3. Samples collected from 30, 40, and 50 feet from boring CB3 were submitted for analysis. The selected soil samples were analyzed for Total Petroleum Hydrocarbons as gasoline (TPHg) by modified EPA Method 8015 and for benzene, toluene, total xylenes and ethylbenzene (BTXE) by EPA Method 8020. The tests were performed by RESNA Environmental Laboratories in Irvine, California, a laboratory certified by the State of California for the analyses. The boring was converted to a 2-inch diameter vapor extraction well with perforations between 30 and 45 feet in depth in case further remediation was necessary. . 4.0 FINDINGS 4.1 Confirmation Boring CB·3 Soil samples collected from boring CB-3 consisted of predominately loose, fine to medium grained sand to a depth of 40 feet. At 40-feet, a silty sand was encountered, which was underlain by a fine to medium grained sand with trace silt. Moderate petroleum odor was noticed in samples from 30 to 45 feet in depth. PID readings ranged from 60 to 600 ppm as shown on the boring log, Plate 3. 4.2 Analytical Results For Soil Samples Soil samples collected from 30,40, and 50 feet from boring CB-3 were submitted to RESNA Environmental Laboratories for analysis of TPHg and BTE & X constituents. The initial analytical results reported by the laboratory were 2,100 parts per million (ppm) TPHg for sample CB3-30, 12,000 ppm TPHg for sample CB3-40, and 7.5 ppm TPHg for sample CB3-50. ~he laboratory ~~.~Lthat th~ o~~E..<J..[ th~__~~!!!pl~~u-ª"-4h the.flt~q!llªtºgr.ª_æ§_.ge~~rated were tY~!fal of Jnineral 'spiri!~__ª1)9}10~ g<is_o]in~_ ~()I!sti~llents.. Additional fuel-fIngerprinting of soil sample 'CB3-40 was requested to confirm the level of petroleum hydrocarbons in the soil. The resulting laboratory report for sample CB3-40 states that the "fuel fingerprint most close!y!es~_I!l1>~~s.1haJ(~f mineral spirits." The concentration of mineral spirits reported in CB3-40 was 5,800 ppm.u, Mineral spirits is a heavy end hydrocarbon more representative of diesel fuel than gasoline. Analytical results for the three soil samples also indicate that only minor concentrations of BTE & X constituents remain in the soil. See Table 2 for analytical results and enclosed analytical reports. RESNA INDUSTRIES INC. FEBRUARY 19, 1993/Page 3 " e REMEDIATION REPORT e ¡~ ~ ARB INC.

The --following is a general risk appraisal of the contaminants left in-place. 5.1 Risk Assessment The following procedure from the Leaking Underground Fuel Tank (LUFf) Field Manual is recommended to detennine the leaching potential for gasoline and diesel constituents and serve as a general risk assessment of soil conditions at this site. U sing the LUff Table 2-1, a score of 49 points was calculated for the leaching potential for this site (Appendix B). This score was based on the depth of groundwater beneath the site to be approximately 145 feet beneath the base of the mineral spirit plume (groondwãterrepõrted to -be 195 feet, September, 1991, J.D. 4, Kern County Water Agency). Based on this score the maximum allowable levels that can be left in-place are 10,000 ppm TPHd, 1 ppm Benzene, and 50 ppm for Toluene, Ethylbenzene, and Xylenes. Analytical results for soil samples with the highest reported hydrocarbon concentration collected from boring CB-3 (CB3-40) and CB-2 (CB2-35) are below these maximum levels. RESNA also concludes that any remaining contaminants in the soil will have low mobility since the volatile components have been removed by the vapor extraction process, leaving mainly heavy-end hydrocarbons in the soil. The threat to the groundwater table beneath the site has been successfully removed. RESNA INDUSTRIES INC. FEBRUARY 19, 1993/page 4 ¡~ ~ e REMEDIATION REPORT e ~ ARB INC. 6.0 RECOMMENDATIONS RESNA recommends that the vapor extraction project be discontinued and no further remedial activities be conducted at this site. If this recommendation is accepted, the vapor extraction wells will be abandoned by filling the wells with neat cement and resurfacing the well locations. RESNA INDUSTRIES INC.

Table 2-1 . Leaching Potential Analysis for Gasoline and Diesel Using Total Petroleum Hydrocarbons(TPH) and Benzene, Toluene, Xylene and Ethylbenzene (BTX&E) The following table was designed to permit estimating the concentrations of TPH and BTX&~ that can be left in place without threatening ground water. Three levels of TPHand BTX&E concentrations were derived (from modeling) for sites which fall into categories of low, medium or high leaching potential. To use the table, find the appropriate description for each of the features. Score each feature using the weighting system shown at the top of each column. Sum the points for each column and total them. Match the total points to the allowable BTX&E and TPH levels. .;, r ~ .! , C't j' Îi. \1 If depth is greater than 5 ft. and less than 25 ft., score 0 points. _ If depth is 5 ft. or less, this table should not be used. If precipitation is over 40 inches, score 0 points. Levels for BTX&E are not applicable at a TPH concentration of 10ppm (gasoline) or 100ppm (diesel) (For explanation see step 6, page 27.) ¡" :1 · I :H I" : I !/ I': ; ;1' I,! 1;:11 ',! -I', ¡:i'; 'I" (;J , ;,¡~ ~,!!
