An Environmental Services Company QUARTERLY GROUNDWATER MONITORING WELL SAMPLING REPORT: On November 29, 1990, Uriah Inc. staff collected one groundwater sample from each of four of the six existing groundwater monitoring wells located at 3505 Pierce Road, Bakersfield, CA. Two of the existing wells (#MW-1 and #MW-2) were not sampled as they were found to contain no groundwater at this time. METHODOLOGY The volume of water stored in each well was calculated by measuring the total well depth and the depth to water using an electrical sounding tape. Each well was then purged of three or more well volumes, using a clean, new, polyethylene bailer until the pH, conductivity, and temperature were stabilized. Measurements of pH, conductivity, and temperature are referenced within APPENDIX "A", attached. In each case, subsequent to the purging of each well, a groundwater sample was collected using a new, disposable, polyethylene bailer lowered into the well just below the water surface. The sample was immediately transferred into two (2) 40 ml. Volatile Organic Analysis (VOA) vials, promptly sealed with teflon-lined, screw caps, labeled, placed on blue ice, and then transported under chain of custody to a certified hazardous waste analytical laboratory for analysis for Total Petroleum Hydrocarbons as Gasoline (TPH-G), benzene, toluene, total xylenes, and ethylbenzene (BTX&E) using D.O.H.S.L.U.F.T. method with individual constituents by EPA Methods 5030/8020. Extracted groundwater, in addition to that acquired for laboratory analysis, was placed into a covered DOT drum for on site storage pending receipt of laboratory data. LABORATORY RESULTS Copies of all laboratory results as received from the certified hazardous waste analytical laboratory are enclosed within APPENDIX "A", attached. Certified analytical results are 464 Lindbergh Avenue · Livermore, California 94550 · (415) 455-4991 summarized in the following chart: SAMPLE # MATRIX TPH-G (B T X E) (ppb) (ppb) MW-1 water --- well dry, no sample obtained--- MW-2 water --- well dry, no sample obtained--- MW-3 water 18,.000 200 3,800 3,110 260 MW-4 water N.D.

An Environmental Services Company June 15, 1990 Mr. Sam Rohn Region Environmental Coordinator Union Carbide- Linde Division 2420 Camino Ramon San Ramon, CA 94583 Re: Completion of Site Characterization at 3505 Pierce Road, Bakersfield, CA. Dear Mr. Rohn: Uriah, Inc. has completed the Site Characterization at the above referenced facility as set forth in our proposal dated March 28, 1990 and according to the guidelines and requirements set forth by the Kern County Department of Environmental Health Services and Central Valley Regional Water Quality Control Board. METHODOLOGY In addition to the three 2" groundwater monitoring wells installed on October 17 and 18, 1989 and November 28, 1989 (see Uriah~s Site Characterization Report dated January 26, 1990), three additional 2" groundwater monitoring wells (MW- 4, MW-5, and MW-6) were installed at the locations shown in Figure 1 attached on May 1, 1990. All groundwater monitoring wells were advanced using a truck- mounted, 8" outside diameter, continuous-flight, hollow-stem auger(s) by employees of Melton Drilling under the direction. of Uriah Staff Geologist, Walter Floyd. Soil samples were obtained at 5 foot intervals for lithologic evaluation (using the Unified Soil Classification System) and/or laboratory analysis. The samples were collected within clean, brass sample tubes (1.92 inches in diameter and 6.0 inches in length) placed within a California Modified Split Spoon Sampler driven through the hollow stem of the drilling auger. Immediately upon the opening of the sampler and the removal of the sampling tubes, the ends of each tube were wrapped in foil, fitted with plastic caps, sealed with black electrical tape, labeled, placed on dry ice, and transported to a certified hazardous waste 464 Lindbergh Avenue · Livermore, California 94550 · (415) 455-4991 analytical laboratory under chain of custody for analysis for Total Petroleum Hydrocarbons as Gasoline (TPH-G), benzene, toluene, total xylenes, and ethylbenzene (BTX&E) using D.O.H.S. L.U.F.T. method and EPA Method 5030/8020. Soil samples obtained below groundwater were collected using a standard split spoon sampler for logging purposes only. All work was reviewed by a California Registered Professional Civil Engineer. Ail soil samples collected during the course of drilling MW- 4 and MW-6 appeared free of significant contamination with no discoloration or odor present. However, a strong hydrocarbon odor was noted during the course of drilling MW-5 beginning at 20' below grade. Groundwater was encountered at a depth of 33 feet in MW-4, MW5, and MW-6. Ail three wells were constructed of 2-inch inside diameter, threaded, Schedule 40 PVC risers attached to 0.020 inch slotted PVC well screen. In each case, the perforated section of the well casing extends 15 feet below and 5 feet above the first encountered groundwater. The sand pack consisting of #3 Monterey Sand extends from the bottom of the boring to 2 feet above the perforations. A 3 foot thick bentonite seal was placed above the sand pack. The remaining annulus was tremie filled with a grout bentonite mixture. The sidewalls of MW-6 caved in after the sand pack was placed creating a natural sand pack above the Monterey Sand pack; therefore, the bentonite plug was not emplaced until a depth of 10 feet. Copies of the Boring Logs and Monitoring Well Construction Details are enclosed as APPENDIX IIBll . Ail tailings from the drilling were placed on visqueen, covered and stored on site pending the receipt of certified laboratory analysis for the determination of proper disposal. The hollow stem augers were steam cleaned prior to arrival on the site. All sampling equipment was steam cleaned prior to being brought on site and between all samplings. Groundwater monitoring well MW-4 was developed and sampled by Mr. Floyd on May 2, 1990. Monitoring wells MW-5 and MW-6 were developed and sampled by Mr. Floyd on May 3, 1990. The three previously installed groundwater monitoring wells (MW-l, MW- 2, and MW-3 were also sampled by Mr. Floyd. Uriah's well, MW- 1 installed on October 17, 1989 had silted up as had a well previously placed at the site by Krazan Associates. In each case,.depth to groundwater was measured using an electric tape and each well was then purged of three well volumes using a WaTerra brand hand pump. Measurements of pH, conductivity, and temperature were acquired and recorded as referenced within APPENDIX "C", attached. Subsequent to the development of each well, a groundwater sample was acquired within a clean, disposable, polyethylene bailer lowered into the well just below the water surface. Upon being brought to grade, the water sample was immediately transferred into two 40 ml Volatile Organic Analysis (VOA) vials. Each vial was promptly sealed with a teflon-lined screw cap, marked, and placed on blue ice for transportation to a State certified hazardous waste analytical laboratory under chain of custody for analysis for Total Petroleum Hydrocarbons as Gasoline (TPH-G) using TPH by D.O.H.S. L.U.F.T. method with individual constituents (BTX&E) using EPA Method 5030/8020. Extracted groundwater, in addition to that acquired for laboratory analysis, was placed into a covered DOT drum for on site storage pending receipt of laboratory data. The wells were surveyed by Mr. Floyd using a transit and rod on May 3, 1990. The elevation of the groundwater was measured with respect to an on site datum which was given an arbitrary elevation of 100 feet. The datum selected was the east end of the loading dock located closest to the liquid Argon storage tank. Data acquired by Uriah to date does not support a Kern County Water Agency Report that the direction of groundwater flow fluctuates seasonally. Additional data should be acquired / anddeveloped prior to the formation of a conclusion in this /~ matter. Uriah measured the flow direction in November of 1989, and found it to be to the Southwest. At this time, recharge from the Kern River would be expected to be at/near its minimum. The flow direction was again measured during May 1990, a time when Spring runoff from the mountains should maximize recharge, however, flow direction was found again to be Southwest (see Figure 2); although slightly different than when previously measured in that contours were somewhat altered. This is probably due to the water table lowering, exposing a gravel lens with differential flow. This gravel lens is depicted in the Geologic Cross Sections attached as Figures 5, 6, and 7. Also, the water table was found to be five feet lower than when measured the previous Fall indicating that no significant recharge had been supplied to this aquifer. Because of below average precipitation, it is possible that the amount of water flowing in the Kern River was insufficient to supply hydraulic recharge.

Non-Detected TPH-G...Total Petroleum Hydrocarbons as Gasoline B...Benzene T...Toluene X...Total Xylenes E...Ethylbenzene Low levels of volatile gasoline compounds were detected throughout the soils encountered during the advancement of MW- 4 (BK-4). This is believed to be vapor phase migration throughout the sands present in the unsaturated zone. Significant levels of soil contamination are present in MW-5 at a depth 20 feet below grade and again at a depth of 30 feet. Low levels of volatile gasoline constituents were detected in soil above 20 feet in MW-5 and are also believed to be vapor phase migration. Only very low levels of toluene were detected in soil at a depth of 5 and 10 feet below grade in MW-6 (BK6). Significant TPH-G and BTX&E contamination of groundwater was found to be present in the three groundwater monitoring wells just newly installed (MW-4, MW-5, and MW-6), as well as the previously installed wells (MW-2 and MW-3), with the exception of MW-1 which resulted in no detectable levels of contamination. The ~ ~.~,- n ..... ern end of the former tank pit (location of ,~T., 3), appears to be the area of maximum contamination. Iso- concentration contour maps are enclosed as Figures 3 and 4. The contour lines between wells were determined mathematically. The lines outside of the wells were approximated. It is believed that the gravel lens in the area of MW-4 and MW-5 is providing a conduit for contaminant migration. It is recommended that a computer model be developed and used to design an in-situ bioremediation treatment system utilizing an injection-extraction system to detoxify soil .and grOundwater simultaneously should remediation become necessary. Until the model is developed, it is proposed that we proceed with quarterly groundwater monitoring of all wells in order to determine contaminant plume~ patterning over time and to assist with the model calibration.

RECOMMENDATIONS FOR COMPLETION OF SITE CHARACTERIZATION AT: 3505 PIERCE ROAD, BAKERSFIELD, CA MARCH 28, 1990 Uriah Inc. An Environmental Services Company March 28, 1990 Mr. Sam Rohn Region Environmental Coordinator Union Carbide- Linde Division 2420 Camino Ramon San Ramon, CA 94538 RE: Recommendations for Completion of Site Characterization at 3505 Pierce Road, Bakersfield, CA. Permit No.: 050033 Dear Mr. Rohn: As indicated within Uriah's report of January 26, 1990, "Site Characterization at Baker's Welding...", data acquired and developed attendant to the installation of three on-site ground- water monitoring wells revealed that, on November 28, 1989, hydraulic gradient in the area under investigation was Southwest. Due to the close proximity of the site boundary to the former tank pit, it appears likely that contaminated groundwater has moved off site- possibly beneath Highway 99. As a result of Uriah's investigative efforts to date, work performed by others, and data available from the Kern County Water Agency, it appears likely that fluctuations in the direction of groundwater flow at the Pierce Road site occur regularly; apparently in response to influences imposed by the seasons and surface waters in the immediate area (i.e. the Kern River, Calloway Canal, and water treatment plant lagoon). Thus, to fully characterize the site in question, it appears necessary to study groundwater conditions as they occur 360 degrees around the former tank pit. - In consideration of/the sandy soils at the Pierce Road site and the resultant C~oclivit~ for vertical rather than lateral migration of contami~nan~, the low levels of gasoline and aromatic constituents previously detected within the soil, and the toxicologic and environmental impact potentials typically associated with these levels, Uriah believes that it is most appropriate to complete characterization of the site through 464 Lindbergh Avenue · Livermore, California 94550 · (415) 455-4991 comprehensive definition of groundwater conditions. It is proposed, therefore, that three additional 2" diameter ground- water monitoring wells be installed to the Northwest, West, and Southwest of the former underground storage tank pit. By circumscribing the source of contamination in this manner, and then sampling and monitoring all wells at least quarterly for one year, elevation and water quality data will be acquired which will: 1) Reveal specific seasonal changes in the flow regime if, in fact, such changes do occur. 2) Determine whether contamination is moving as a non-aqueous phase liquid and/or as dissolved constituents. 3) Provide data which will permit development of isoconcentration contour maps which may be used to determine how contaminant migration patterns change in response to seasonal fluctuations in the flow regime. 4) Permit modeling of transport factors, biotic and abiotic attenuation pathways; and the development of a risk assessment which will address fully the potential for public health and environmental impacts. If the proposal for the installation of additional groundwater monitoring wells is approved, each boring would be advanced to a depth of approximately 40 feet, 15 feet below the point at which groundwater is expected to be encountered. Drilling would be accomplished with a truck/trailer mounted rig equipped with 8" outside diameter, continuous-flight, hollow stem augers. Each boring would be continuously logged using the Unified Soil Classification system and samples would be obtained at five foot intervals and at the top of the capillary fringe within a California Modified Split Spoon Sampler driven through the hollow stem of the drilling auger(s). Immediately upon the opening of the sampler, the ends of the 1.92 inch diameter x 6.0 inch long, clean brass sampling tubes contained within would be wrapped with aluminum foil, fitted with plastic caps, sealed with black electrical tape, labeled, and placed on dry ice for transportation to Chromalab, Inc. of San Ramon, CA, or other certified hazardous waste analytical laboratory, under chain of custody. It is proposed that soil samples be analyzed for Total Petroleum Hydrocarbons as Gasoline (TPH-G), benzene, toluene, total xylenes, and ethylbenzene (BTX&E) using EPA Methods 5030/8015-8020. The limits of detection for TPH-G in soil is li0 parts per million (ppm), and for benzene, toluene, total xylenes, and ethylbenzene 0.05 ppm. Monitoring wells will be constructed in accordance with protocol set forth on Page #1 of Appendix "A". The slotted section of the well will extend 15 feet below and 5 feet above the first encountered water. The sand pack will extend 18-24 inches above the slotted section. A 2-4 foot thick bentonite seal will be placed above the sand pack. The remaining annulus will be tremie filled with grout. Proposed well development procedures appear as Pages #2 and 3 of Appendix "A". Fluids produced from the development process would be held on site in a secured container until laboratory results are received and appropriate disposal protocol developed. Tailings will be stored on site on visqueen and covered also pending receipt of laboratory data. Samples from each developed well would be acquired with a clean acrylic or teflon bailer lowered into the well to a point immediately below the water surface. Each water sample would be transferred to one (1) amber glass sample bottle and two (2) Volatile Organic Analysis (VOA) vials, promptly sealed with teflon-lined screw caps, labeled, placed on blue ice and trans- ported to Chromalab, Inc. under chain of custody for analysis for TPH-G and BTX&E using EPA Methods 5030/8015-602. The limit of detection for TPH-G in water is 30 ppb (parts per billion), and for benzene, toluene, total xylenes, and ethylbenzene 0.3 ppb. Assurance of sample quality will be provided through the use of blanks and/or duplicates of soil and water samples as specified by the Kern County Department of Environmental Health Services. All sampling equipment will be steam cleaned or thoroughly scrubbed with alconox solution followed by a distilled water rinse prior to being brought on site and between all samplings. All professional work will be performed by/under the direction of a Uriah staff geologist supervised by Mr. Eddy Tabet, a Registered Professional Engineer. If you have any questions regarding this proposal, or if we may otherwise of assistance, please contact either of the undersigned at (415) 455-4991.

The well was developed with the use of a hand pump until the groundwater was clay and/or silt free. The well was then purged using a hand pump until the pH, conductivity, and temperature were stabilized and the groundwater was observed to be relatively free of sandy silt and other grit material. The pH, conductivity, and temperature measurements acquired are referenced on Chart I, attached. The groundwater sample was collected with a new, disposable polyethylene bailer and appeared clean and contained little, if any, suspended soil sediment. The sample was promptly transferred from the bailer into two (2) 40 milliliter capacity Volatile Organics Analysis (VOA) vials and a one liter amber glass sample bottle, immediately sealed with teflon-lined screw caps, labeled, placed on blue ice and transported to a certified hazardous waste analytical laboratory under chain of custody for analysis for using EPA Methods . All development and sampling equipment was cleansed with a solution of Trisodium Phosphate (TSP) prior to use.

APPENDIX B HEALTH AND SAFETY PROCEDURES FOR EXPLORATORY SOIL BORINGS TO BE PERFORMED AT 3505 PIERCE ROADt BAKERSFIELDt CA: The following protocol for personnel involved in the above referenced project is considered generally appropriate; however, modifications may be imposed by their consultants, and/or the County of Kern in response to site specific conditions. HEALTH AND SAFETY STAFF Mr. Walter Floyd, Uriah Staff Geologist PUBLIC HEALTH/ENVIRONMENTAL HAZARD ASSESSMENT Hazards associated with the performance of exploratory soil borings are those related to: 1). Exposure to the hydrocarbon contaminated soils being explored, 2). The potential for ignition of flammable/explosive vapors, and 3). The physical hazards associated with working with/near heavy equipment. HAZARDS OF CHEMICAL EXPOSURE All soils to be handled are contaminated with gasoline and diesel fuel. The most toxic constituents present are believed to be the aromatic constituents of gasoline- benzene, toluene, xylenes, and ethylbenzene (BTX&E); with benzene the most toxic of these having been identified as a carcinogen and forming as much as 3.5% of gasoline by weight. Due to the volatile nature of the aromatics, the most significant route of potential exposure would appear to be via inhalation. Secondary routes of exposure would include dermal (by direct contact with contaminated soil) and by the incidental ingestion of gasoline contaminated dusts. The measures prescribed for the minimization of risks associated with the aforementioned routes of exposure are described below. HAZARDS ASSOCIATED WITH FLAMMABLE VAPORS Although by and large the levels of gasoline within soil are not extremely high, it is recognized that there is a potential for vapors to collect within the flammable range. The measures for early detection of these vapors are described below. PHYSICAL HAZARDS The physical hazards attendant to the performance of exploratory soil borings are those associated with working on/near mechanized equipment. Appropriate procedures attendant to the operation of equipment to be utilized on this project are already in force and are well known to our staff. Further, work-rest cycles will be established and adhered to so as to provide adequate rest periods; liquids will also be available to preclude problems associated with heat stress. RISK FACTORS AND ASSOCIATED MITIGATION PROCEDURES Type of Risk Route of Exposure Mitigating Factor(s) Chemical .............. Inhalation ........... -Air purifying respirators with organic vapor and dust filters. -A hydrocarbon vapor survey meter will be used to determine exposure. Chemical ......... Dermal/Ingestion .......... -Optimum use of equipment to minimize direct exposure to the soil. -Use of protective clothing. -The nature of the project does not involve the uncontrolled release of toxic materials. Flammable Vapors ....... --. ................. -A hydrocarbon vapor meter will be used to determine the percent of the lower explosive limit (LEL) present at the excavation. Physical ............... --. ................. -Physical hazards attendant to this project are no different from those associated with drilling projects involving non- regulated materials. -The use of trained and experienced staff; properly attired and using appropriate and well-maintained equipment. WORK AREA Only authorized personnel will be permitted within the work area. This area will be clearly marked and monitored. DECONTAMINATION PROCEDURES General procedures for handwashing and disposal of soiled clothing will be adhered to. Ur, An Enuironmental SITE CHARACTERIZATION AT: BAKER'S WELDING 3505 PIERCE ROAD, BAKERSFIELD, CA JANUARY 26, 1990 464 Lindbergh Avenue · Livermore, California 94550 · (415) 455-4991 Uriah Inc. An Environmental Services Company January 26, 1990 Mr. Sam Rohn Union Carbide- Linde Division 2420 Camino Ramon San Ramon, CA 94583 Re: Site Characterization At 3505 Pierce Road, Bakersfield, CA Dear Mr. Rohn: Uriah, Inc. staff have completed the installation of three (3) two-inch groundwater monitoring wells at the above referenced location according to the guidelines and requirements set forth by the Kern County Department of Environmental Health Services and the Central Valley Regional Water Quality Control Board in the area formerly occupied by a 10,000 gallon underground unleaded gasoline storage tank...the focus of a known fuel leak event in December, 1987, in order to determine the lateral and vertical extent of fuel hydrocarbon contamination of soil and groundwater. METHODOLOGY A literature review conducted by the previous consultant Krazan and Associates, revealed a report by the Kern County Water Agency, 1987, which stated that" The groundwater gradient is from the southeast to northwest, 'perpendicular to the Kern River." The report went on to say that the direction of groundwater flow may reverse seasonally depending upon whether the Kern River is acting as a source of recharge or discharge. With this in mind, it was decided to place a well to the southeast (#MW-l) in what was believed to be the downgradient position on October 17, 1989. A second well (#MW-2) was advanced adjacent to the building Northeast of the tank pit on October 18, 1989. (See Figure 1 for specific well locations). The location of all wells was pre-approved by Delores Gough, Hazardous Materials Specialist for the Kern County Department of Environmental Health Services. 464 Lindbergh Avenue · Livermore, California 94550 · (415) 455-4991 An attempt was made to utilize an existing groundwater monitoring well installed by Krazan and Associates in order to determine groundwater gradient; however, we were unable to utilized the well due to the fact that the screened interval had completely filled with silt. It was also noted upon visual inspection of the well, that no surface cover was in place over the well. This well was subsequently abandoned with the prior approval of Dan Starkey, Hazardous Materials Specialist for the Kern County Department of Environmental Health Services, on November 28, 1989 by filling it with grout and advancing a new well in its place (see Figure 1) on that same day. Uriah's groundwater monitoring wells were advanced using a truck-mounted, 8" outside diameter, continuous-flight, hollow-stem auger(s) by employees of BSK & Associates Drilling Company for #MW-1 and #MW-2 and employees of Melton Drilling for #MW-3 under the direction of Uriah Staff Geologist, Walter Floyd. Soil samples were obtained at 5 foot intervals for lithologic evaluation (using the Unified Soil Classification System) and/or laboratory analysis. The samples were collected 'within clean brass sampling tubes (1.92 inches in diameter and 6 inches in length) placed within a California Modified Split spoon Sampler driven through the hollow stem of the drilling auger. Immediately upon the opening of the sampler, the ends of the sampling tubes were wrapped in aluminum foil, fitted with plastic caps, sealed with black electrical tape, labeled, placed on dry ice, and transported to a certified hazardous waste analytical laboratory under chain of custody for analysis. Soil samples obtained below groundwater were collected using a standard split spoon sampler for logging purposes only. All %~ork performed was under the supervision of a Registered Professional Civil Engineer. All soil samples collected during the course of drilling #MW-1 and #MW-2 appeared clean with no discoloration or odor noted to be present. Groundwater was encountered at a depth of 27' in both #MW-1 and #MW-2. Soil samples obtained at depths of 5, 15, and 25 feet in both #MW-1 and #MW-2 were subsequently analyzed for Total Petroleum Hydrocarbons as Gasoline (TPH-G), benzene, toluene, total xylenes, and ethylbenzene (BTX&E) using DoO.H.S.L.U.F.T. method for TPH-G and EPA Method 8020 for individual constituents. The third monitoring well (#MW-3) was advanced in the same manner as previously referenced. During the course of drilling this %~ell, a strong hydrocarbon odor of the soil was noted beginning at 20 feet below grade. Groundwater was encountered at a depth of 28.5 feet. Soil samples were collected at depths of 5, 10, 15, 20, 25, and 28 feet in the same manner.as noted above and then analyzed for Total Petroleum Hydrocarbons as Gasoline (TPH- G), benzene, toluene, total xylenes, and ethylbenzene (BTX&E) using D.O.H.S.L.U.F.T. method for TPH-G and EPA Method 8020 for individual constituents. Ail three wells were constructed of 2-inch inside diameter, threaded, Schedule 40 PVC risers attached to 0.020 inch slotted PVC well screen. In each case, the slotted casing extends above the groundwater surface to account for fluctuating groundwater levels. A 3 foot bentonite seal was placed above the screened interval in each well to protect groundwater from surface water infiltration. Each well was completed with a cement grout mixture pumped into the boring with a tremie line. Copies of the Boring Logs and Monitoring Well Construction Details are enclosed as Attachment B. Ail tailings from the drilling were placed on visqueen, covered and stored on site pending the results of certified laboratory analysis for the determination of proper disposal. The hollow stem augers were steam cleaned prior to arrival on the site. All sampling equipment was steam cleaned prior to being brought on site and between all samplings. Groundwater monitoring wells #MW-1 and #MW-2 were developed and sampled by Mr. Floyd on October 19, 1989. Monitoring Well #MW-3 was developed and sampled on November 29, 1989. (See The Groundwater Monitoring'Well Development and Sampling Report enclosed as Attachment B. The wells were surveyed by Uriah, Inc. staff using a transit and rod on November 28, 1989. An on site datum was used to obtain an elevation of the wells relative to each other. Groundwater gradient was determined to be South 30 degrees West, or roughly parallel to the Kern River (see Figure 2 attached). This most recent data differs from gradient information supplied by the Kern County Water Agency report on water conditions in Improved District #4, 1987 Report. According to the report, groundwater flow was Northwest, perpendicular to the Kern River, which would be the expected direction of groundwater flow when free of other influences. The lagoon near the water treatment plant approximately a quarter of a mile away and the Calloway Canal appear to have a significant influence on the hydraulic gradient at this site.

An Environmental Services Compan GROUNDWATER MONITORING WELL DEVELOPMENT AND SAMPLING REPORT On October 19, 1989, Uriah, Inc. staff collected one ground- water sample from each of the-newly installed monitoring wells (~MW-1 and ~MW-2) located at Baker's Welding, 3505 Pierce Road, Bakersfield, CA. On November 29, 1989, a water sample was also collected from the. third newly installed well (#MW-3). Methodology The well depth and depth to groundwater for each well were measured using an electric measuring tape. Groundwater monitoring wells #MW-1 and ~MW-2 were purged using a clean, acrylic bailer. Well ~MW-3 was purged'using a hand pump. Water was purged from the wells until the pH, conductivity, and temperature were stabilized and the groundwater was observed to be relatively free of sandy silt and other grit material. The pH, conductivity, and temperature measurements acquired are referenced on Chart I, attached. The groundwater sample was collected from each well with an acrylic bailer which had been cleansed with a trisodium phosphate solution (TSP) and then rinsed thoroughly with distilled water prior to collecting the sample. The sample in each case appeared clean and contained little, if any, suspended soil sediment. The sample was promptly transferred from the bailer into two (2) Volatile Organics Analysis (VOA) vials, immediately sealed with teflon-lined screw caps, labeled, placed on blue ice and transported to a certified hazardous waste analytical laboratory under chain of custody for analysis for Total Petroleum Hydrocarbons as Gasoline (TPH-G), benzene, toluene, total xylenes, and ethylbenzene (BTX&E) using EPA Methods 5030/602. Laboratory ResUlts The laboratory results as received'from the certified hazardous waste analytical laboratory are enclosed. 464 Lindbergh Avenue · Livermore, California 94550 · (415) 455-4991 Conclusions Ail constituents analyzed for in groundwater sample #MW-1 were found to be below detection limits. However, all constituents analyzed for in groundwater sample ~MW-2 and #MW-3 were found to be above detection limits except for total xylenes in sample #MW-2.

An Environmental Services Company PROPOSAL FOR SITE CHARACTERIZATION AT: 3505 PIERCE ROAD, BAKERSFIELD, CA 464 Lindbergh Avenue · Livermore, California 94550 · (415) 455-4991 Uriah Inc. An Environmental Services Company Nay 22, 1989 Mr. Sam Rohn Union ~arbide- Linde Division 2420 Camino Ramon San Ramon, CA ~4583 Re: Proposal For ~ Site Characterization gt 3505 Pierce Road, Bakersfield, California Dear ~. Rohn: Uriah, Inc. is pleased to present the following proposal For a site characterization to de%ermine the vertical and lateral exbent of Fuel hydrocarbon contamination of soil and groundwater at the above referenced site. SITE HISTORY The site is currently occupied as Baker's ~elding & Supply Company and is located along the western side of Pierce Road between Gilmore gvenue and ~otty Street in Bakersfield, California. The site consists of a warehouse/office complex with an attached retail showroom; loading docks; above-ground liquid propane, oxygen, nitrogen, and argon stomago tanks as ~ell as a 10,000 gallon underground gasoline storage tank. The tank is approximately 18 years old and has been used For the storage of unleaded gasoline For company-operated vehicles and equipment. There is a septic system located to the east of ~he building. The entire site is paved ~ith asphaltic concrete and is enclosed by a six-foot chain link Fence. gccordin~ to inFo~mation available, on Novembem 10,000 ~allon underground gasoline sto~a~e tank was precision 464 Lindbergh Avenue · Livermore, California 94550 · (415) 455-4991 tested and was Found to be uncertiFiable by a Petro-tite'line _. and tank tightness test. The tank passed the tightness test after the leak was located and repaired. In December, 1987, employees noticed a sluggishness in the pumping of the Fuel From the tank until on December' 2B, 1987, no Fuel could be pumped From the tank.. Rt that time, Fuel was discovered in a manway around the submersible pump. The Fuel along with a small amount of soil, was removed. From the manway. It was suspected at that time that the Fuel leaked From the union between the sumersible pump and the Red Jacket Leak Detector. The reconciliation of inventory records indicated that between 200 and 600 gallons of Fuel may have been lost. ~ preliminary site characterization was performed by Krazan ~ ~ssociates, Inc. on May 17, 1988 to determine whether fuel hydrocarbons were present in the soil and/or groundwater in the vicinity of the unleaded gasoline storage tank in question. During the course of the investigation, a single soil boring was advanced near the submersible pump end of the underground storage tank to a depth of approximately 40 Feet below grade. ~ groundwater monitoring well was also advanced to a depth of approximately 40 Feet with groundwater encountered at an approximate depth of 24 feet. /'he monitoring well was placed at the end opposite the fill end, or North of the underground tank. (See site map attached). The results of the analysis of soil and groundwater samples obtained from the exploratory boring and the monitoring well and analyzed by BC Laboratories, Inc., a California State Certified Hazardous Waste ~nalytical Laboratory located in Bakersfield, CA, disclosed significant concentrations of Total Petroleum Hydrocarbons as Gasoline in both soil and groundwater. (See copies of the analytical data attached). RE6ION~L HYDRO~EOL06IC CONDITIONS ~ccording to Krazan & ~sociates, Inc., the topography of the referenced site is Fairly level with the subsurface materials composed primarily of unconsolidated materials deposited by the Kern River and its tributaries. These ~lluvial deposits are generally composed of sands, silty sands, and some minor gravel derived From Sierra Nevada source rocks. The site is located within the San Joaquin Valley Hydrologic Study ~rea. The area is primarily an arid to semi-arid environment. Thirty-seven groundwater basins and areas of potential groundwater storage have been identified in this area. The storage capacity is known to be approximately 5?0 million acre-feet. There is a two-aquifer system in the vicinity of this project site. ~n upper, unconfined aquifer which is separated from the lower, confined aquifer by an aquitard known as the "300-foot clay". This clay layer is believed to be present beneath the site. According to Krazan & ~ssociates, Inc., the groundwater level below this site is approximately 20 feet. The groundwater gradient is from southeast to northwest, perpendicular to the Kern River. The groundwater level below the project site is highly variable and depends on the volume of water in the Kern River.~ in the Kern River and the Calloway Canal influences the~ydrolic~conditions at the project site by providing a sourc~r-~,g--~'~harge to the unconfined aquifer. SCOPE OF ~0RK In order to define the lateral and vertical e~ent of soil and groundwater contamination known to exist at the 3505 Pierce Road,~rsfield, C~ facility, Uriah, Inc. proposes to advance eight (~e~loratory soil borings around the area occupied by the 1~00 gallon unleaded gasoline storage tank. The borings would be advanced with a truck/trailer mounted 8" outside diameter, continuous-flight, hollow-stem auger to a depth at which groundwater is encountered. Ail borings would be continuously logged by a Uriah staff geologist under the supervision of Mr. Eddy Tabet, a Registered Professional Engineer. Soil samples would be obtained at five foot intervals For lithology and/or laboratory analysis as deemed appropriate by the on site professional. Soil samples would be obtained by driving a split spoon sampler through the hollow stem of the drilling auger(s). The samples would be collected within clean brass sample tubes (1.92 inches in diameter and 6 inches in length) fitted within the split spoon sampler. Immediately upon being removed from the sampling unit, the ends of each brass tube would be promptly wrapped in aluminum foil, Fitted with plastic caps, sealed with black electrical tape, labeled, placed on dry ice, and transported to a certified hazardous waste analytical laboratory under chain of custody for analysis for Total Petroleum Hydrocarbons as Gasoline (TPH-G) with benzene, toluene, total xylenes, and ethylbenzene (BTX&E) distinction using EPA Methods 5020/8015 and 8020. ~ grab water sample will be collected From each boring using a clean teflon bailer lowered down into the boring below the water surface. Each water sample will be collected in one (1) glass amber sample bottle and two (2) Volatile Organics Analysis vials, promptly sealed with teflon-lined, scre~ caps, labeled, placed on blue ice, and transported to a certified hazardous - ' waste analytical laboratory under chain of custody for analysis For Total Petroleum Hydrocarbons as 8asoline (TPH-G) with benzene, toluene, xylenes, and ethylbenzene (BTXSE) distinction using EP~ Methods 5030/801S and 602. ~11 sampling equipment .will be decontaminated between sampling intervals by First scrubbing with trisodium phosphate (TSP) solution and water and then rinsing with deionized water. The augers used by the drill rig will either be changed or steam cleaned between borings. ~11 tailings From the borinEe will be placed on visgueen and stored on site pendinE results of laboratory analysis. The borinEs will be baokfilled ~ith' concrete or as specified by the Kern County Environmental Health Department. The detection limits of the certified hazardous waste anal~ioal laboratory are as follows: ~N~LYTE DETECTION LIMIT Soil (ppm) ~later (ppb) Total Petrolsum Hydrocarbons as Gasoline (TPH-G) ................ 1.0 30.0 Benzene ............................ 0.05 0.3 Toluene ............................ O. 1 O. 3 Xylenes ............................ O. 1 O. 3 Ethylbenzene ....................... O. 1 O. 3 The proposed locations of all borings are indicated on the attached site map. The location of the borings were selected based upon the known groundwater gradient in the area, seasonal variations in groundwater levels and the potential extent of contamination from information available. Subsequent to its acquisition, contaminant plume boundary data ~ill be developed and a Final report prepared which will present textual and ~raphic representations of contaminant concentrations, provide information re~arding local hydrogeolo~y, predict migration, and public health and environmental impact potentials ~ith the use of computer modeling. Based on the data acquired, a meaningful remedial action plan ~ill be discussed. This site characterization is based on the information currently available. Should significantly greater contamination be encountered, additional work may be required to adequately evaluate the extent of the -- - c o nt ami nat i o n. ~ Health ~nd Safety Plan has been prepared and is attached in ~ppendix C. Uriah will obtain all necessary permits for the proposed work. For your convenience, this document is presented in a form which may be accepted as an agreement. If you find this proposal acceptable, please indicate your concurrence by returning a signed copy with your initial payment. Thank you For considering Uriah, Inc. as a service provider. you have any questions, or if' we may otherwise be of assistance, please contao~ one of the undersiEned at (415) Sincerely, ~alter Flo~d ~eoloEist and Doniso g.

Health and Safety Plan APPENDIX C HEALTH AND SAFETY PROCEDURES FOR EXPLORATORY SOIL BORINGS TO .... BE PERFORMED AT 3505 PIERCE ROADt BAKERSFIELDt CA: The following protocol for personnel involved in the above referenced project is considered generally appropriate; however, modifications may be imposed by their consultants, and/or.the County of Kern in response to site specific conditions. HEALTH AND SAFETY STAFF Mr. Walter Floyd, Uriah Staff Geologist PUBLIC HEALTH/ENVIRONMENTAL HAZARD ASSESSMENT Hazards associated with the performance of exploratory soil borings are those related to: 1). Exposure to the hydrocarbon contaminated soils being explored, 2). The potential for ignition of flammable/explosive vapors, and 3). The physical hazards associated with working with/near heavy equipment. HAZARDS OF CHEMICAL EXPOSURE Ail soils to be handled are contaminated with gasoline and diesel fuel. The most toxic constituents present are believed to be the aromatic constituents of gasoline- benzene, toluene, xylenes, and ethylbenzene (BTX&E); with benzene the most toxic of these having been identified as a carcinogen and forming as much as 3.5% of gasoline by weight. Due to the volatile nature of the aromatics, the most significant route of potential exposure would appear to be via inhalation. Secondary routes of exposure would include dermal (by direct contact with contaminated soil) and by the incidental ingestion of gasoline contaminated dusts. The measures prescribed for the minimization of risks associated with the aforementioned routes of exposure are described below. HAZARDS ASSOCIATED WITH FLAMMABLE VAPORS Although by and large the levels of gasoline within soil are not extremely high, it is recognized that there is a potential for vapors to collect within the flammable range. The measures for early detection of these vapors is described below. PHYSICAL HAZARDS The physical hazards attendant to the performance of exploratory soil borings are those associated with working on/near mechanized equipment. Appropriate procedures attendant to the operation of equipment to be utilized on this project are already in force and are well known to our staff. Further, work-rest cycles will be established and adhered to so as to provide adequate rest periods; liquids will also be available to preclude problems associated with heat stress. RISK FACTORS AND ASSOCIATED MITIGATION PROCEDURES Type of Risk Route of Exposure Mitigating Factor(s) Chemical .............. Inhalation ........... -Air purifying respirators with organic vapor and dust filters. -A hydrocarbon vapor survey meter will be used to determine exposure. Chemical .............. Inhalation ........... -Optimum use of equipment to minimize direct exposure to the soil. -Use of protective clothing. -The nature of the project does not involve the uncontrolled release of toxic materials. Flammable Vapors ....... --. ................. -A hydrocarbon vapor meter will be used to determine the percent of the lower explosive limit (LEL) present at the excavation. Physical ............... --. ................. -Physical hazards attendant to this project are no different from those associated with drilling projects involving non- regulated materials. -The use of trained and experienced staff; properly attired and using appropriate and well-maintained equipment.

It was understood from information provided to this office that this investigati°n was required by the Kern County Environmental Health Department in a letter dated 3anuary 20, 1988. This investigation was to take place in the immediate vicinity of a 10,000 gallon underground gasoline storage tank. INTRODUCTION The project site is currently developed as Baker's Welding & Supply Company and is located along the western side of Pierce Road between Gilmore Avenue and Getty Street in Bakersfield, California. This property, which is owned by Cooper and Bridges of Bakersfield, corresponds with the NWl/t, of Section 23, T29S R27E of the Mount Diablo Base Line and Meridian. The facility consists of a warehouse/office complex with an attached retail showroom; loading docks; above-ground liquid propane, oxygen, nitrogen, and argon storage tanks; and a 10,000 gallon underground fuel storage tank. This underground storage tank has been used for the storage of unleaded gasoline for company-operated vehicles and equipment. The tank is approximately 18 years old. A septic system is located east of the building. Main Office: Fresno/Clovis · 3860 N. Winery · Fresno, California 93726 · (209) 291-7337 Bakersfield (805) 393-2343 [] Visalia (209) 625-8251 [] Merced (209) 383-3993 Page No. 2 Proj. No. ESS-023 The entire site, with the exception of the building areas, is paved with asphaltic concrete and is surrounded by a six-foot chain link fence. On November 25, 1986, this underground storage tank was precision tested and was found to be uncertifiable by a Petro-tite line and tank tightness test. After the leak was located and repaired, the tank passed the tightness test. It was understood from information provided to this office that the contractor who repaired the line indicated that the leak was minor in nature and that he felt that little product had been lost. At the beginning of December, 1987, the employees noticed a sluggishness in the pumping of fuel from the unleaded storage tank. On December 28, 1987, employees were unable to pump gasoline from the underground storage tank, and fuel was discovered in the manway around the submersible pump. The fuel, as well as a_s__m__.al._l._a~_ount of soil, was removed from the manway. It was suspected that the fuel leaked from the union between the submersible pump and the Red Jacket Leak Detector. -.~- Reconciliation of inventory records indicate that between 200 and 600 gallons of fuel may have been lost. However, these values are approximate. The underground storage facility is not currently in operation pending the results of this site characterization. GEOLOGIC CONDITIONS The topography of the site is relatively level. The subsurface materials are composed primarily of unconsolidated materials deposited by the Kern River and its tributaries. These alluvial deposits are generally composed of sands, silty sands, and some minor gravel and are derived from Sierra Nevada source rocks. KRAZAN & ASSOCIATES, INC. Page No. 3 Proj. No. Eg$-023 REGIONAL HYDROLOGIC CONDITIONS The project site is located within the San 3oaquin Valley Hydrologic Study Area, which is primarily an arid to semi-arid environment. Within. the study area, 37 ground water basins and areas of potential ground water storage have been identified. Storage capacity in this study area is approximately 570 million acre-feet. Useable storage totals 80 million acre-feet. Fresh water bearing deposits (generally alluvium) have a maximum thickness of %#00 feet. The area in which the project site is located is part of the Kern County Basin. This basin currently has a declining groundwater surface problem but the severity of the problem is lessened by utilizing waters from the State Water Project. The Kern County Water Agency is one of the regulatory agencies that govern surface waters in this area. A two-aquifer system exists in the vicinity of the project site. The upper, unconfined aquifer is separated from the lower, confined aquifer by an aquitard known as the "300-foot clay". This clay layer is believed to be present beneath the project site. The depth to groundwater below the site in September, 1987 was approximately 20 feet. This groundwater depth was obtained from Well H53, which is adjacent to the Teamster's Union Hall across the street from Baker's Welding & Supply. The depth to groundwater in Well H53 has been as low as 6g feet in the fall of 1976, and as high as lg feet in September 1956. The groundwater gradient is from southeast to northwest, perpendicular to the Kern River. This information was obtained from the Kern County Water Agency report on water conditions in Improvement District t/g, 1997 Report. The groundwater level below Baker's Welding is highly variable and depends on the volume of water in the Kern River. The volume of water in the Kern River near the site is the sum of the flow measured at the Calloway Weir plus the inflow from Turnout #g. Flow in the Kern River and the Calloway Canal influences the hydrologic conditions at the project site by providing a source of recharge to the unconfined aquifer. Recent flow rates for the Kern KRAZAN & ASSOCIATES~ INC. Page No. # Proj. No. E88-023 River are summarized below. A flow rate of approximately 1,500 acre-feet at the Calloway Weir is necessary for surface flow to occur in the Kern River at Highway 178 (Rosedale Highway). Based on projected flow rates, the water level below Baker's Welding dr Supply should drop until November, 1988.

SCOPE OF THE INVESTIGATION The scope of this investigation was generally limited to the area in the immediate vicinity of the unleaded gasoline storage tank. One soil boring was advanced near the submersible pump end of the underground storage tank to KRAZAN & ASSOCIATES, INC. Page No. 5 Proj. No. E88=023 obtain soil samples to determine the vertical extent of fuel constituents in the subsoils. Qne §roundwater monitorin§ well was placed near the fill end of the tank, in a historically down-gradient direction, to detect any fuel constituents that might be present in groundwater. Upon installation of this well, water samples were obtained to determine the presence and concentration of petroleum constituents in groundwater. The soil profile was logged during the drilling process, and a literature survey was conducted to describe the regional geologic and hydrologic conditions. METHODOLOGY [n order to investigate those potentials described in the Scope of the Investigation section of this report, the following methods were employed: 1. All necessary permits were obtained prior to the commencement of the investigation. 2. The exploratory soil boring and groundwater monitoring well were advanced by means of a Mobil Drill B-61 truck-mounted drilling rig, utilizing hollow stem auger. Drilling fluids were not used while advancing the boring or monitoring well boring. 3. Drillin§ and sampling equipment used for the installation and sampling were steam-cleaned prior to advancing each soil boring. #. One exploratory soil boring was placed at a location immediately north of the underground storage tank. .5. The soil boring was advanced to a depth of 15 feet below existir~g grade. The depth of 15 feet below grade was selected based upon review of published data regarding depths to groundwater in the vicinity of the project sites and a de§tee of conservatism necessary to leave an undisturbed bu£fer between the bottom of the boring and groundwater. 6. Soil samples were obtained by means of pushing stainless steel tubes at discrete intervals (ASTM D-I587-86, "Thin-walled Tube Sampling of Soils"). KRAZAN 8: ASSOCIATES, INC. Page No. 6 Proj. No. E88-023 7. Soil samples were obtained at 5-foot intervals, commencing at an approximate depth of 5 feet below existing grade. $. Auger cuttings were placed in U.S. Department of Transportation approved [7H barrels and sealed. Each barrel was marked with identification as to the soil boring and depth from which it came. The barrels were left on site pending the proper disposal by the property owner, following results of the chemical analysis. 9. One groundwater monitoring well was placed in a location that is, historically, downgradient from the tank. The well boring was advanced to a depth of approximately 40 feet below grade. Soil samples were obtained at ~ foot intervals for logging purposes and possible chemical analysis. The well was constructed with PVC blank well casing and slotted section. The design of the monitoring wells will accommodate a 20 foot potential fluctuation of groundwater levels at the project site. I0. The groundwater monitoring well generally consists of PVC Schedule 40 flush thread solid pipe above PVC Schedule 40 pipe with 0.020" slotted openings. The filter medium for the saturated zone consists o[ a washed #16 Monterey sand. The filter medium extends to 2 feet above the slotted interval. Above the filter medium, a seal . of 3-foot thickness was established utilizing 3/S" bentonite pellets. The remainin§ annulus (£rom the bentonite seal to the surface vault) consists of a 6-sack sand/cement slurry, with approximately 3% bentonite added to reduce shrinkage away from the well pipe and to reduce the heat generated from hydration. ii. The surface vault provides a flush surface access to the locked well head. 12. Alter well development and stabilization, the well was sampled from the interface to detect the presence o[ free product on groundwater. 13. .All samples were collected, maintained and transported under chain of custody protocol to a state-approved laboratory for chemical analysis. Selected soil samples were analyzed to detect the presence and concentration of benzene, toluene, xyJenes, ethylbenzene and total petroleum hydrocarbons (gas). The water sample was analyzed to detect the presence of purgeabie aromatics and total purgeable hydrocarbons by EPA Method Number 602. 14. All field work was conducted under standards set forth by industry and deemed acceptable by various regulatory agencies.

RESULTS OF THIS INVESTIGATION Soil Profile One exploratory soil boring and one groundwater monitoring well were advanced to a maximum depth of #0 feet below existing grade at the project site. The soil profile generally consisted of a fine to medium grained silty sand from the surface to an approximate depth of 9 feet below existing grade. A poor to weJ] graded sand with lenses that contain minor silt and gravel were encountered to the maximum depth of our soil borings~ which were terminated at an approximate depth of #0 feet below existing grade. For more detailed information regarding subsoils encountered at the project site, please refer to the logs of borings included in Appendix A of this report. Groundwater Conditions Groundwater was encountered in our monitoring well boring at an approximate depth of 2# feet below the existing grade. Review of the Kern County ~Yater Agency Report, May 1987~ tends to corroborate our field observations. The project site was located near the Kern River, which provides recharge to the unconfined aquifer. The proximity of the project site to the Kern River and the Calloway Canal, and the historic fluctuations in groundwater level suggest that those features influence the hydrologic conditions at the project site. RESULTS OF CHEMICAL ANALYSIS A total of 4 soil samples and one groundwater sample were obtained for chemical analysis from the project site. The samples were submitted to a state-approved laboratory and analyzed to detect the presence of those KRAZAN & ASSOCIATES, INC. Page No. $ Proj. No. E88-023 constituents associated with unleaded gasoline. Soil samples were analyzed to detect presence and concentration of benzene, toluene, isopropyl benzene, para-xylene, meta-xylene, ortho-xylene, ethy]benzene, petroleum hydrocarbons and total purgeable hydrocarbons.

DISCUSSIONS OF FINDINGS One soil boring and a groundwater monitoring well were placed in the immediate vicinity of the underground storage tank location in order to obtain data which would help to identify the presence and possible movement of contaminants in subsoils and groundwater. KRAZAN & ASSOCIATES, INC. Page No. 11 Proj. No. E88-023 The soils encountered in exploratory borings at the project site consisted generally of sands and silty sands. Those soil types are generally associated with having somewhat higher rates of permeability than silts or clays. Groundwater was encountered at an approximate depth of 2~ feet below the existing grade at the project site. Review of published data regarding groundwater conditions in the area of the subject property confirmed our findings. Chemical analysis of the soil samples obtained show moderate levels of petroleum constituents present at depth. At 20 feet below grade~ the concentration of total purgeable hydrocarbons present in the representative soil sample was 170.93 ppm. The chemical analysis of the groundwater sample obtained from the monitoring well has also shown petroleum constituents to be present. The constituents noted from that analysis suggest that the character of the contaminant is that of gasoline. The compounds noted from volatile organics analysis of the groundwater sample obtained from the monitoring well were limited to benzene~ toiuene~ and xylenes. The results of the total purgeab]e hydrocarbons conducted on the groundwater sample confirm the presence of petroleum constituents with a concentration of 61.5 ppb. Benzene concentration in water was 35.7 ppb. CONCLUSIONS Based upon observations made at the time of our field investigation~ coupled with the results of chemical analysis conducted on subsoil samples obtained at the time of our drilling~ and professional interpretation along with interviews with Baker's Welding & Supply personnel, the following conclusions were made; KRAZAN & ASSOCIATES~ INC. Page No. 12 Proj. No. E88-023 1. The soil profile at the subject property generally consisted o£ sands, and silty sands from the surface to an approximate depth of #0 feet below existing grade. 2. The sands and silty sands associated with the subject property were soil types generally associated with moderate to high rates of permeability. 3. Based upon review of published data regarding historic groundwater depths in the vicinity of the subject property, groundwater has been assumed to be at an approximate depth of 20-40 feet below the existing grade. Groundwater was encountered during our drilling operations at a depth of 24 feet below existing grade. Both groundwater level and direction of gradient are anticipated to fluctuate with changing flow levels in the Kern River. 4. The results of the chemical analysis conducted on soil and water samples obtained at the project site had shown moderate levels of petroleum constituents (purgeable hydrocarbons) in soil and in groundwater (170.93 ppm in soil; 61~ ppb in groundwater). ~. Based upon review of the results of chemical analysis, coupled with review of the historic and site specific groundwater conditions associated with the subject property and its vicinity, it would appear that contamination from the underground fuel storage tank at the project site has impacted groundwater resources. The full extent of the contamination present in the subsoils and groundwater associated with this project site are unknown at this time. LIMITATIONS The findings of this report were based upon the results of field and laboratory investigations, coupled with the interpolation of subsurface conditions associated with our soil borings. Therefore, the data are accurate only to the degree implied by review of the data obtained and professional interpretation. The exploratory soil boring and monitoring well were located in the field by review of available maps and by pacing or tape measurement from existing landmarks, as interpreted from available maps. Therefore, the soil boring and monitoring well locations should be considered accurate only to the degree implied by the methods used to locate them. KRAZAN & ASSOCIATES, INC. Page No. 13 Proj. No. Egg-023 Chemical testing was done by labs approved by the State of California Department of Health Services. The results of the chemical testing is accurate only to the degree of the care of insuring the testing accuracy and the representative nature of the soil and water samples obtained. The findings presented herewith were based upon professional interpretation using state of the art methods and equipment and a degree of conservatism deemed proper as of the report date. It is not warranted that such data cannot be superseded by future geotechnical, environmental or technological developments.
