In addition, this report presents the remediation status for the Site. This work was conducted in response to the State of California ' Regional Water Quality Control Board — Central Valley Region (RWQCB) letter dated August 26, 2003, and also in compliance with subsequent RWQCB directives, the latest of which is dated May 29, 2007. ' Discussion of Groundwater Monitoring and Remedial Data Based on the groundwater analytical data from the Third Quarter 2007, groundwater beneath ' the Site is no longer impacted with fuel constituent COCs from past activities, except for a reoccurrence of MtBE at 100 µg/L.in MW-2. Historically, the principal impact to groundwater was by extremely low concentrations of MtBE (the only COC to have been reported since ' October 10, 2003). MtBE has been reported as non-detect at MW-1 since July 2004 and at MW-3 since October 2004. Throughout that time,the groundwater table elevation fell and rose as much as four (4) feet. Generally, when the groundwater elevation rises it will bring groundwater into contact with residual fuel mass, if present, in the `smear zone' and dissolved- ' phase concentrations will increase. Therefore, it is unlikely that any significant fuel- hydrocarbon mass remains beneath the Site. The reoccurrence of MtBE at MW-2 is anomalous, since MtBE has not been reported at that well for ten (10) quarters. E2C will evaluate the laboratory analytical data generated from the next sampling event to determine if additional actions, if any, are warranted. ' In, June 2006, (as reported in E2C's Second Quarter 2006 Groundwater Monitoring Report, Third Quarter 2006 Groundwater Monitoring Report, Additional Assessment Report of Findings ' and Remediation Status Report, dated November 28, 2006) E2C conducted soil vapor extraction activities to assess whether an unidentified source of fuel constituents was present at the Site. During the testing, the low vapor influent concentrations reported during the additional assessment testing (consisting of an 8-hour continuous test) compared closely to the influent concentrations reported at remedial system shutdown in August 2004. These low concentrations indicate the presence of very minor residual fuel constituent impact in the vadose zone, if any. A significant quantity of fuel constituents were removed from startup through the end of August 2004. -The fuel constituent removal rate showed a rapidly declining trend, from an initial rate of nearly 600 lbs/day at start up (May 14, 2004) to a rate at system shut down of 33 lbs/day (see Table 5 graph). This declining rate suggested a rapid depletion of the `source' material. MtBE concentrations in groundwater were eliminated immediately. This operational data, combined with the June 2006 additional assessment test data, indicated' that remediation may be complete. In order to verify this E2C, implemented an approved Pilot Test Workplan to assess whether a residual mass of fuel constituents occurs near the former UST pit. In May 2007, (as reported in E2C's Residual Mass"Assessment Report of Findings, Human Health Risk Assessment and Request for Site Case .Closure, dated June 11, 2007) E2C ' conducted soil vapor extraction activities for an assessment of residual fuel and to perform a human health risk assessment. Based on current concentrations of fuel constituents in the subsurface at the Site, non-detect in groundwater (except for a reoccurrence of 100 gg/L of MtBE at MW-2) and very low in soil (35 ppmV at end of May 2007 testing), SVE remedial ' E2C Remediation 1 ' Proiect Number 1812BK26 September 24 2008 operations have reduced subsurface fuel constituents to levels that do not pose threats to human health or groundwater. ' Conclusions Based on the site assessment work and groundwater monitoring data obtained at the Site to ' date, E2C concludes the following: ■ In the Third Quarter 2007 the groundwater flow direction was interpreted to be southerly at a gradient of 0.0078 ft/ft; ' ■ The average groundwater table elevation decreased 3.16 feet since the Second Quarter 2007. Recharge and or discharge from the Stine Canal, located along the eastern boundary of the Site, does not appear to control groundwater flow beneath the Site; ' ■ In the Third Quarter 2007, groundwater samples were reported as non-detect for the fuel constituent COCs, except for the reported 100 Vg/L of MtBE at MW-2. COCs have been reported as non-detect for thirteen (13) consecutive quarters at MW-1 and for ' twelve (12) consecutive quarters at MW-3; ■ During its limited operation period (May 14, 2004 through August 31, 2004), between 7,700 Ibs and 8,000 Ibs of fuel constituents were removed from the subsurface at the ' Site; ■ Additional Assessment testing (consisting of an 8-hour continuous test) conducted on June 15, 2006 at vapor extraction point VE-FD demonstrated that no significant fuel ' constituent mass is present beneath the former fuel dispenser island, no benzene or MtBE were present, and that only very minor fuel constituents might remain in the vadose zone; ' Additional Assessment testing (conducted between May 29, 2007 and May 31, 2007) at vapor extraction points VES-As, VES-Bs, VES-Ad, VES-Bd and VES-C demonstrated that no significant fuel constituent mass is present beneath the former UST area, no ' benzene or MtBE were present, and that only very minor fuel constituents might remain in the vadose zone; ■ An assessment of human health risk shows that limited residual fuel impact to medium- depth soils beneath the Site poses no threats to human health or the environment; and • Based on current concentrations of fuel constituents in the subsurface at the Site, non- detect in groundwater (excepting the reoccurrence of MtBE at MW-2) and very low in soil (35 ppmV at end of May 2007 testing), SVE remedial operations have reduced subsurface fuel constituents to levels that do not pose threats to human health or the environment; and ' Based on the above conclusions, it is E2C's professional opinion that further remediation at this Site is not necessary at this time, however, continued monitoring at is warranted to verify the recent detection 'and to evaluate the need for additional remediation, if 1 warranted. Recommendations ' Based on the data presented in this report and the above conclusions, E2C makes the following recommendations: • Continue groundwater monitoring on a semi-annual basis; ■ Analyze groundwater samples for BTEX and five fuel oxygenates. (includes MtBE) using EPA Method 8260b and TPHg using EPA Method 8015M on a quarterly basis; and • Continue status reporting on a semi-annual basis until MtBE concentrations at MW-2 warrant Site Closure. ' E2C Remediation 2 ' Project Number 1812BK26 September 24,2008 r1.0 INTRODUCTION E2C Remediation (E2C) has completed semi-annual groundwater monitoring activities, which were conducted in the Third Quarter 2007, for the Former Niagara Car Wash facility (Site) located at 1700 Stine Road in Bakersfield, California. In. addition, this report presents the remediation status for the Site. This work was conducted in response to the State of California Regional Water Quality Control Board — Central Valley Region (RWQCB) letter dated August r 26, 2003, and also in compliance with subsequent RWQCB directives, the latest of which is dated March 12, 2007. 1.1 Site Description The Site is currently utilized as an operating car.wash (W hitewater Car Wash) located in ' Bakersfield, California, at 1700 Stine Road between Stine Road and Hasti Acres Drive (see. . Figures 1A and 1 B for Site Location Maps). The Site encompasses approximately 1.7 acres and is located approximately 200 feet south of Ming Avenue. The Site is located in Section 11, Township 30 South, Range 27 East MDBM. Three (3) 12,000:gallon gasoline underground storage tanks (USTs) were located as shown on Figure 2 (Site Plan). The USTs were removed in April 2003. The fuel dispensers under the ' canopy area were removed, as well as the associated piping. One (1) 2,000-gallon waste oil UST is still located at the Site as shown on Figure 2. ' 1.2 Site Hydrogeology Regionally, the depth to groundwater had been estimated at approximately 190 feet bgs ' according to the 1996 Water Supply Report published by the Kern County Water Agency. During March 2003 drilling activities, first encountered groundwater was found at a depth of approximately 163 feet bgs. In July 2005 groundwater was encountered at approximately 170 feet bgs. ' The surrounding area well survey identified four (4) production wells within a 2,500-foot radius of the Site. All of these wells were noted to be,operating during a field reconnaissance. 1 The Stine Canal (irrigation and runoff) traverses the Site from northeast to southwest between the carwash building"and Stine Road. The canal continues beneath the Site as a concrete pipe culvert which extends from north of Ming Avenue to the southern boundary of the Site. The canal is an unlined channel to the south of the Site. Water generally flows in the canal on a year-round basis. 1.3 Site History A detailed Site History was discussed in the June 17, 2003 report, `Site Characterization Report of Findings, Report of Surrounding Area Well Survey, SVE System Installation and Pilot Test Report of Findings & Workplan to Implement Remedial Action, Former Niagara Car Wash, 1701 Stine Road, Bakersfield,'California'(1 RAP). In March 2003, E2C installed one (1) groundwater monitoring well to assess groundwater conditions at the Site. In addition, six (6) VE wells were installed and two (2) 40-foot soil 1 borings were advanced on either side of the`dispenser islands. Upon completion of the well installations, the remediation wells were plumbed to a manifold in the equipment pad area. This work was reported in the Site Characterization. Report of Findings, dated June 17, 2003. In a letter, dated August 26, 2003, the RWQCB requested additional groundwater characterization. ' E2C Remediation 3 ' Prot ect Number 1812BK26 September 24.2111 Groundwater monitoring wells MW-2 and MW-3 were installed during the week of September 28, 2003, after which the wells were developed. Initial.groundwater monitoring/sampling was conducted at the new wells in October 2003 and that data was reported in the Fourth Quarter 2003 Groundwater Monitoring Report, dated February 2004. In May 2005, vapor extraction well (VE)-VE-FD was installed at the Site, as approved by the RWQCB in a letter dated March 15, 2005. Installation of the well was reported in the following 1 document: First Quarter 2005 Groundwater Monitoring. Report, Second Quarter 2005 Groundwater Monitoring Report, Third Quarter 2005 Groundwater Monitoring Report, and Remediation Status Report, Former Niagara Carwash, 1701 Stine Road, Bakersfield, California, ' dated September 5, 2005. In June 2006, (as reported in E2C's Second Quarter 2006 Groundwater Monitoring Report, Third Quarter 2006 Groundwater Monitoring Report, Additional Assessment Report of Findings and Remediation Status Report, dated November 28, 2006) E2C conducted soil vapor extraction activities to assess whether an unidentified source of fuel constituents were present at the Site. During the testing, the, low vapor influent concentrations reported during the additional assessment testing (consisting of an 8-hour continuous test) compare closely to the influent concentrations reported at remedial system shutdown in August 2004. These low concentrations indicate the presence of very minor residual fuel constituent impact in the vadose zone. Since the radius of influence at VE-FD is at least 105 feet, the additional assessment testing ' demonstrated that no significant fuel constituent mass is present within the radius of influence of VE-FD. If significant residual fuel constituents were present in the vadose zone beneath the former fuel dispensers, or in the vicinity of the.former USTs, reported influent concentrations would have reflected this and resulted in higher influent concentrations that increased throughout the duration of the test. 1 In May 2007, (as reported in E2C's Residual Mass Assessment Report of Findings, Human Health Risk Assessment and-Request for Site Case Closure, dated June 11, 2007) E2C conducted soil vapor extraction activities for an assessment of residual fuel and to perform a human health risk assessment. Based on current concentrations of fuel constituents in the subsurface at the Site, non-detect in groundwater and very low in soil (35 ppmV at end of May 2007 testing), SVE remedial operations have reduced subsurface fuel constituents to levels that do not.pose threats to human health or groundwater. In I r 9 7 In a letter, May 2 , 200 , the RWQCB requested a reduction in the frequency of the monitoring to a semi-annual basis. E2C Remediation 4 Proiect Number 1812BK26 September 24 2008 2.0 SEMI-ANNUAL GROUNDWATER MONITORING Semi-annual groundwater-monitoring activities were conducted on July 17, 2007. ' 2.1 Groundwater Elevation Monitoring The initial task performed was evaluating the wells for presence of free-product using a clear ' bailer. Free-product was not present in any well. The depth of freestanding groundwater was then measured to the nearest one-hundredth (0.01) of a foot using a Solinst water level indicator and an attached measuring tape. Current semi-annual groundwater monitoring data are summarized in Table 1 and are presented with historical groundwater elevation data in Table 2. ' The groundwater flow direction for the Third Quarter 2007 has been interpreted as southerly at a gradient of 0.0078 foot of vertical drop.per foot of horizontal distance (ft/ft) (see Figure 3), a very flat gradient. In the Third Quarter 2007, the groundwater table elevation decreased an average of approximately 3.16 feet across the Site (see Table 2). Based on historical groundwater flow directions interpreted at the Site, it does not appear that recharge or discharge from the Stine.Canal control the groundwater flow direction beneath the ' Site. This is likely due to the depth (156 feet bgs or greater) at which groundwater occurs beneath the Site. Therefore, groundwater flow beneath the Site may be regionally controlled and/or controlled by regional pumping.southeast of the Site. 2.2 Groundwater Sampling Groundwater was purged at each monitoring well by hand bailing using a new disposable bailer. A minimum of 3 casing volumes was removed from each well prior to sampling groundwater., A casing volume is calculated by multiplying the height of the freestanding water column in the well by the cross-sectional area of the well casing. The temperature, pH and conductivity of the purged water were measured periodically to verify sufficient purging, as indicated by stable measurements on field instruments. When the measurements were within 10% of the previous readings-the groundwater was considered stable for sampling (see Appendix A for Third Quarter 2007 groundwater purge data sheets). Each sample was collected using a new disposable bailer. Liquid in the bailer was decanted into two 40-milliliter volatile organic analysis (VOA) vials. Each VOA was sealed using a tight fitting Teflon-lined screw cap. Care was taken so that no headspace or bubbles existed after sealing each VOA with the lid. All samples were labeled and documented on a Chain-of- ' Custody record immediately after sealing. The samples were placed into an iced cooler maintained at 4° Centigrade for transport to the analytical laboratory. Note: For this sampling event, the sample labeled MW-4 on the Chain-of-Custody is a duplicate of the sample from ' MW-3. 2.2.1 Purge Water Recycling Groundwater sampling purge water was transported to Remedy Environmental Services of Bakersfield, California for recycling (Appendix C contains copies of the non-hazardous purge water transport manifests and the recycling certificates). ' E2C Remediation 5 1 Proiect Number 1812BK26 September 24.2008 2.3 Groundwater Chemical Analyses Groundwater samples were transported to and analyzed at ProVera Analytical Laboratories, ' Inc. (ProVera) (State Certification #2606) of Bakersfield, California in accordance with State guidelines and EPA protocols for the following: • Total Petroleum Hydrocarbons as gasoline (TPHg) using EPA Method 8015M; ' • The volatile aromatic compounds of benzene, toluene, ethylbenzene, and xylenes (total) (BTEX) using EPA Method 8260b; and • The five fuel oxygenates of methyl tertiary-butyl ether (MtBE), tertiary-butyl alcohol (TBA; a.k.a. tert-butanol), di-isopropyl ether (DIPE), ethyl-tertiary-butyl ether (ETBE), and tertiary amyl methyl ether (TAME) using EPA Method 8260b. Note: In a letter, dated February 9, 2006, the RWQCB directed the.discontinuation of annual analysis of groundwater samples using EPA Method 8260b full-scan. 'in a letter, dated May 29, 2007, the RWQCB requested a reduction in the frequency of monitoring to a semi-annual basis. 2.3.1 Summary of Third Quarter 2007 Groundwater Analytical Data The analytical laboratory report for the Third Quarter 2007 is included as Appendix B. The July 1 17, 2007 groundwater analytical data are presented in Table 1, are presented with historical analytical data in Table 3, and are summarized following: • BTEX compounds were reported as non-detect at all three (3) wells; • TPHg was reported as non-detect afall three (3) wells; ■ MtBE was reported at one (1) well (MW-2) at a concentration of 100 4g/L; and • TAME, TBA, DIPE, and ETBE were reported as non-detect at all three (3) wells. ' 2.4 AB 2886 Compliance Groundwater analytical data for this quarter have been uploaded to the GeoTracker database in accordance with State of California Assembly Bill 2886 (AB 2886). Groundwater elevation data have also been uploaded to the database. Finally, a copy of this status report has also been uploaded to the database. Appendix D contains copies of the available upload confirmation ' reports through the Third Quarter 2007. Any upload confirmation reports not included in this report will be included in the next semi-annual status report. ' 2.5 Discussion of Groundwater.Monitoring Data Based on the groundwater analytical data from the Third Quarter 2007, groundwater beneath the Site is no longer impacted with fuel constituent COCs from past activities, except for a reoccurrence of MtBE at 100 µg/L in MW-2. Historically, the principal impact to groundwater was by extremely low concentrations of MtBE (the only COC to have been reported since ' October 10, 2003). MtBE has been reported as non-detect at MW-1 since July 2004 and at MW-3 since October 2004. Throughout that time, the groundwater table elevation fell and rose as much as four (4) feet. Generally, when the groundwater elevation rises it will bring groundwater into contact with residual fuel mass, if.present, in the `smear zone' and dissolved- 1 phase concentrations will increase. Therefore, it is unlikely that any significant fuel- hydrocarbon mass remains beneath the Site. The reoccurrence of MtBE at MW-2 is anomalous, since MtBE has not been reported at that well for ten (10) quarters. E2C will evaluate,the laboratory analytical data generated from the next sampling event to determine if additional actions, if any, are'warranted. 1 E2C Remediation 6 Proiect Number 1812BK26 September 24.2008 ' 3.0 REMEDIATION STATUS REPORT Remedial operations at the Site were previously conducted utilizing a vapor extraction system ' (VES). To date, six (6) vapor extraction (VE) wells have been installed at the Site. Two (2) of the VE wells (VES-AD and VES-BD) are screened deep (approximately 75 to 110 feet bgs), three (3) (VES-AS, VES-BS and VE-FD) are screened shallow (approximately 10 to 75 feet bgs) and one (1) (VES-C) is screened at medium depth (approximately 40 to-85 feet bgs). On May 14, 2004, the VES equipment (Baker Furnace 250-CFM Thermal/catalytic Oxidizer with a propane-powered generator) was brought on line. The system, prior to shutdown on August 31, 2004, was operating with wells VES-AS, VES-BS, and VES-C open and with VES-AD and VES-BD closed. This wellfield configuration yielded the highest influent concentration. During remedial system operations, the wellfield configuration was adjusted on a weekly basis to 1 optimize the system effectiveness. Note: During the first ten (10) days of system operation, the oxidizer shut down intermittently ' due to low temperature or low pressure, so that only seven (7) days of actual runtime were achieved. This problem was repaired and the system operated continuously until August 31, 2004 when the SJVAPCD Startup Inspection was conducted. During the inspection, the SJVAPCD Inspector indicated that an individual Permit To Operate (PTO) would also be required for the generator providing the electrical power. As such, the remediation system was shut down pending receipt of the additional PTO. It must be noted that the SJVAPCD originally permitted the site remediation equipment with a propane generator. A permit application for the generator was prepared and submitted to the SJVAPCD for their review and approval. On December 8, 2004, the SJVAPCD issued the PTO. Upon receipt of the PTO, E2C reviewed the permit conditions, which included a mandatory requirement for independent monthly testing of the generator emissions. This required testing consisted of monthly Site visits to measure/test the generator emissions for an extensive suite of analytes. E2C solicited bids from several independent testing contractors and determined that testing costs and propane costs would increase operational costs significantly, and that electrical service provided.by PG&E would be substantially more cost-effective. Therefore, E2C applied to PG&E for installation of the permanent power supply. E2C received the contract documents from PG&E and found the cost to install permanent power to be excessive. 1 However, on June 15, 2006, E2C conducted additional assessment testing on extraction well VE-FD, and the results of that testing demonstrated.the presence of very minor fuel constituent impact to the vadose zone soils. In May 2007, E2C conducted an assessment of residual subsurface gasoline mass at the Site using SVE testing at existing VE wells in the area of the former underground storage tanks (USTs). The work was conducted in accordance with a Workplan dated February 22, 2007, which was approved by the RWQCB by letter, dated March 12, 2007. Initially, all VE wells were individually tested to determine which well, or combination of wells, would yield the highest influent concentration(s). VES-C showed the highest concentrations during this testing; however, concentrations dropped at this well until at the end of testing 28 hours later, the concentration at VES-C was only 35 ppmV, a fuel hydrocarbon removal rate of ' only 2.1 pounds per day (Ibs/day). This indicates that continued operation of an SVE system would extract soil vapors at less than 2.1 Ibs/day over any long-term period. Additionally, testing of the shallow and deep zones individually and collectively yielded very low (25-50 ' ppmV) influent concentrations. As such, the minor mass of fuel hydrocarbons remaining beneath the Site does not warrant continued remedial action. E2C Remediation 7 1 Project Number 18126K26 September 24.2008 Based on current concentrations of fuel constituents in the subsurface at the Site, non-detect in groundwater (except for a reoccurrence of 100 gg/L of MtBE at MW-2) and very low in soil (35 ppmV at end of May 2007 testing), SVE remedial operations have reduced subsurface fuel ' constituents to levels that do not pose threats to human health or the environment. 3.1 Historical Remedial System Operations ' 3.1.1 Thermal Oxidizer The remedial system consisted of vapor extraction using a Baker Furnace 250-CFM thermal oxidizer capable of adding a modular catalytic cell as concentrations fall. The unit's minimum operating temperature in thermal mode was 1,400 deg. F. This temperature was set to maximize vapor oxidation at reasonable electrical unit cost via the propane-powered generator. The unit was equipped with a regenerative or PD type vapor extraction blower. For improved reliability and safety, the valve controls, actuators, and components were controlled by relay logic switches. The unit was equipped with a water knockout pot, automatic air dilution Icapability, and a noise-reducing muffler. This equipment was designed to shut down and lock out in the event of a system malfunction. The various safety features include high and low oxidizer bed temperatures, high and low ' blower pressure, high intake'LEL, high and low air pressure, high and low exhaust temperature, and water knockout malfunction sensor. At least 99% destruction efficiency is stated in the manufacturer's specifications for the unit. Prior to shutdown, the remediation equipment was monitored on a weekly basis to perform routine maintenance, record oxidizer parameters (temperature, flow rate and operating hours)' and measure influent and effluent constituent concentrations. Although the oxidizer parameters were continuously recorded digitally on a Zip disk, weekly monitoring of these parameters verifies accuracy of the measuring devices. Fuel constituent concentrations were also measured in the field using a portable hydrogen flame ionization detector (FID) and the data were used in applicable formulas to calculate the mass of fuel constituents removed on both.a monthly and cumulative basis. ' Adjustments were continually made to the configuration of the unit to maximize vapor flow from the wellfield while maintaining the chamber temperature above 1,400 degrees Fahrenheit (°F) as required in the SJVAPCD permit and below the manufacturer's recommended temperature limit of 1,850 OF in the stack. Note: Due to declining influent concentrations, a catalytic cell was added to the system on August 18, 2004. ' 3.2 Compliance with SJVAPCD Permit To Operate Compliance was demonstrated by monitoring of the influent and effluent streams with a FID or PID instrument during regular system operations and weekly monitoring visits. From May 14 through May 24, 2004, the influent averaged 4,800 ppmv with `zero' effluent, which equated to 100% destruction efficiency. Field records including sampling results, cumulative runtime, flow rate, and catalytic oxidizer temperature will be maintained and retained for a minimum of two (2) years. When operating, system operation temperature was maintained at a minimum of 1,400 degrees Fahrenheit (°F) in the combustion chamber of the thermal oxidizer, and at a,minimum of 600°F after the August 18, 2004 conversion to catalytic operation. I3.2.1 August 2004 Influent/Effluent Analytical Data On August 31, 2004, during the SJVAPCD Startup Inspection test, Tedlar@ bag samples were ' collected from the influent and effluent sample ports. The samples were submitted to ProVera for analyses Total Petroleum Hydrocarbons as gasoline (TPHg) using Modified EPA Method ' E2C Remediation 8 1 Proiect Number 1812BK26 September 24 2008 ' TO-3 and for volatile aromatics (BTEX) using Modified EPA Method TO-15. The results are summarized following (the data was previously reported): ' The influent BTEX components were reported at a total concentration of 64 ppmv, and the effluent concentration was reported as non-detect; ■ The influent TPHg were reported at.a concentration of 500 ppmv, and the effluent concentration was reported as non-detect; and Based on this data, the TPHg/BTEX destruction efficiency was 100%. 3.3 Fuel Hydrocarbon Mass Removal Rates Hydrocarbon removal rates were estimated using two different methods of calculation. The first method uses a straight-line extrapolation of influent measurements based on actual hourly run- time. Using this method, the mass of fuel constituents removed, from startup through August 31, 2004, was calculated at approximately 7,700 pounds (Ibs) (see Table 4). The second - nmethod uses the average-influent-over the-average daily--ruri=time per month.. Using-this-____- - method, the total mass of fuel constituents removed, from startup through August 31, 2004, was calculated at approximately 8,000 Ibs (see Table 5). ' 3.4 Discussion of Remedial Efficiency A significant quantity of fuel constituents were removed from startup through the end of August 2004. The fuel constituent removal rate showed a rapidly declining trend, from an initial rate of nearly 600 Ibs/day at start up (May 14, 2004) to a rate at system shut down of 33 Ibs/day (see Table 5 graph). This declining rate suggested a.rapid depletion of the `source' material. MtBE concentrations in groundwater were eliminated immediately. This operational data, combined 1 with the recent additional assessment test data, indicated that remediation may be complete. In order to verify this E2C, implemented the approved Pilot Test Workplan in May 2007 to assess whether an unidentified mass of fuel constituents exist near the former.UST pit. The results of the SVE testing in the former UST area demonstrated that benzene and MtBE were absent in the subsurface soils, and that the minor residual-mass offuel hydrocarbons in the vadose zone did not pose a risk to human health or the environment. 4.0 ' CONCL USIONS Based on the site assessment work and groundwater monitoring data obtained at the Site to date, E2C concludes the following: ■ In the Third Quarter 2007 the groundwater flow direction was interpreted to be southerly at a gradient of 0.0078 ft/ft; ■ The average groundwater table elevation decreased 3.16 feet since the,Second Quarter 2007. Recharge and or discharge from the Stine Canal, located along the eastern boundary of the Site, does not appear to control groundwater flow beneath the Site; ■ In the Third Quarter 2007, groundwater samples were reported as non-detect for the fuel constituent COCs, except for the reported 100 pg/L of MtBE at MW-2. COCs have been reported as non-detect for thirteen (13) consecutive quarters. at MW-1 and for ' twelve (12) consecutive quarters at MW-3; ■ During its limited operation period (May 14, 2004 through August 31, 2004), between 7,700 Ibs and 8,000 lbs of fuel constituents were removed from the subsurface at the Site; ' E2C Remediation 9 Project Number 1812BK26 September 24.2008 ■ Additional Assessment testing (consisting of an 8-hour continuous test) conducted on June 15, 2006 at vapor extraction point. VE-FD demonstrated that no significant fuel constituent mass was present beneath the former fuel dispenser island, no benzene or MtBE were present, and that only very minor fuel constituents might remain in the vadose zone; ■ Additional Assessment testing (conducted between May 29, 2007 and May 31, 2007) at vapor extraction points VES-As, VES-Bs, VES-Ad, VES-Bd and VES-C demonstrated that no significant fuel constituent mass is present beneath the former UST area, no benzene or MtBE were present, and that only very minor fuel constituents might remain in the vadose zone; ■ An assessment of human health risk showed that limited residual fuel impact to medium-depth soils beneath the Site poses no threats to human health or, the environment; and ■ Based on current.concentrations of fuel constituents in the subsurface at the Site, non- detect in groundwater (excepting the reoccurrence of MtBE at MW-2) and very low in soil (35 ppmV at end' of May 2007 testing), SVE remedial operations have reduced subsurface fuel constituents to levels that do not pose threats to human health or the environment; and ■ Based on the above conclusions, it is E2C's professional opinion that further remediation at this Site is not necessary at this time, however, continued monitoring at is warranted to verify the recent detection and to evaluate the need for additional remediation, if warranted. 5.0 RECOMMENDATIONS Based on the data presented in this report and the above conclusions, E2C makes the following recommendations: ■ Continue groundwater monitoring on a semi-annual basis; ■ Analyze groundwater samples for BTEX and five fuel oxygenates (includes MtBE) using EPA Method 8260b and TPHg using EPA Method 8015M on a quarterly basis; and ■ Continue status reporting on a semi-annual basis until MtBE concentrations at MW-2 warrant Site Closure. 1 1 I E2C Remediation 10 Project Number 1812BK26 ember 24'200 e Sent 8 . 6.0 LIMITATIONS AND REPORT CERTIFICATION E2C performed this investigation in accordance with the generally accepted standards of care existing in,California;at this time.'

In addition, this report presents the remediation status for the Site. This work was conducted in response to the State of California Regional Water Quality Control ' Board —Central Valley Region (RWQCB) letter dated August 26,-2003, and also in compliance with subsequent RWQCB directives, the latest of which is dated May 29, 2007. Discussion of Groundwater Monitoring and Remedial Data Based on the groundwater analytical data from the First Quarter 2008 semi-annual event, groundwater beneath the Site is no longer impacted with fuel constituent COCs from past - - ---.----.activities,_.except-for.-.a_-reoccurrence_of_-MtBE_at._219.µg/L_in-MW-2. the principal impact to groundwater was by extremely low concentrations of MtBE (the only COC to have been reported since October 10, 2003). MtBE has been reported as non-detect at MW-1 since ' July 2004 and at MW-3 since October 2004. Throughout that time, the groundwater table elevation fell and rose as much as four (4) feet. Generally, when the groundwater elevation. rises it will bring groundwater into contact with residual fuel mass, if present, in the `smear zone' ' and dissolved-phase concentrations.will increase. Therefore, it is unlikely that any significant fuel-hydrocarbon mass remains beneath the Site. MtBE was reported at MW-2 in July 2007 at a concentration of 100 µg/L and at 219 gg/L in ' February 2008. The reoccurrence of MtBE at MW-2 is unclear, as MtBE had not been reported, at that well for ten (10) quarters. E2C will evaluate the laboratory analytical data generated from the next sampling event to determine if additional actions, if any, are warranted. ' In June 2006, (as reported in E2C's Second Quarter 2006 Groundwater Monitoring Report, Third Quarter 2006 Groundwater Monitoring Report, Additional Assessment Report of Findings , ' and Remediation Status Report, dated November 28, 2006) E2C conducted soil vapor extraction activities to assess whether an unidentified source of fuel constituents was present at the Site. During the testing, the low vapor influent concentrations reported during the additional assessment testing (consisting of an 8-hour continuous test) compared closely to the influent concentrations reported at remedial system shutdown in August 2004. These low concentrations indicate the presence of very .minor residual fuel constituent impact in the ' vadose zone, if any. A significant quantity-of fuel constituents were removed from startup through the end of August 2004. The fuel constituent removal rate showed a rapidly declining trend, from an initial rate of ' nearly 600 lbs/day at start up (May 14, 20 04) to a rate at system shut down of 33 lbs/day (see Table 5 graph). This declining rate suggested a rapid depletion of the `source' material. MtBE concentrations in groundwater were eliminated immediately. This operational data, combined with the June 2006 additional assessment test data, indicated that remediation may be complete. In order to verify this E2C, implemented an approved Pilot Test Workplan to assess whether a residual mass of fuel constituents occurs near the former UST pit. In May 2007, (as reported in E2C's Residual Mass Assessment Report of Findings, Human Health Risk Assessment and Request. for Site .Case Closure, dated June 11, 2007) E2C conducted soil vapor extraction activities`for an assessment of residual fuel and to perform a human health risk assessment. Based on current concentrations of fuel constituents in the E2C Remediation 1 ' Pro'e t Number 1812BK26 October 3 2008 subsurface at the Site, non-detect in groundwater (except for a reoccurrence of 100 gg/L of MtBE at MW-2) and very low in soil (35 ppmV at end of May 2007 testing), SVE remedial operations have reduced subsurface fuel constituents to levels that do not pose threats to ' human health or groundwater. Conclusions ' Based on the site assessment work and groundwater monitoring data obtained at the Site to date, E2C concludes the following: ■ In February 2008 the groundwater flow direction was interpreted to be west- ' southwesterly at a gradient of 0.0067 ft/ft; The average groundwater table elevation decreased 3.14 feet since July 2007. Recharge._and_or_discharge_from_the_Stine_Canal,_located_along_the eastern bounda_ry_of ' the Site, does not appear to control groundwater flow beneath.the Site; ■ In February 2008, groundwater samples were reported 'as non-detect for the fuel constituent COCs, except for the reported 219 gg/L of MtBE at MW-2. COCs have been reported as non-detect for fourteen (14) consecutive quarters at'MW-1 and for thirteen (13) consecutive quarters at MW-3; • DIPE, ETBE, TAME and TBA have been reported as non-detect at all three (3) Site monitoring wells since they were installed in 2003; • During its limited operation period (May 14, 2004 through August 31, 2004), between 7,700 Ibs and 8,000 Ibs of fuel constituents were removed from the subsurface at the Site; • Additional Assessment testing (consisting of an 8-hour continuous test) conducted on June 15, 2006 at vapor extraction point VE-FD demonstrated that no significant fuel constituent mass is present beneath the former fuel dispenser island, no benzene or MtBE were present, and that only very minor fuel constituents might remain in the ' vadose zone; ■ Additional Assessment testing (conducted between May 29, 2007 and May 31, 2007) at vapor extraction points VES-As, VES-Bs, VES=Ad, VES-Bd and VES-C demonstrated ' that no significant fuel constituent mass is present beneath the former UST area, no benzene or MtBE were present, and that only very minor fuel constituents might remain in the vadose zone; ' An assessment of human.health risk shows that limited residual fuel impact to medium- depth soils beneath the Site'poses no threats to human health or the environment; and ■ Based on current concentrations of fuel constituents in the subsurface at the Site, non- detect in groundwater (excepting the reoccurrence of MtBE at MW-2) and very low in. soil (35 ppmV at end of May 2007 testing), SVE remedial operations have reduced subsurface fuel constituents to levels that do not pose threats to human health or the ' environment; and ■ Based on the above conclusions, it is E2C's professional opinion that further remediation, at this Site is not necessary at this time; however, the MtBE concentration at MW-2 ' warrants continued monitoring to determine whether additional remedial efforts will be required. ' E2C Remediation 2 Proiect Number 1812BK26 October 3.2008 Recommendations Based on the data presented in this report and the above conclusions, E2C makes the following recommendations:, ■ Continue groundwater monitoring on a semi-annual basis; ■ Analyze groundwater samples for BTEX and five fuel oxygenates (includes MtBE) using EPA Method.8260b and TPHg using EPA Method 8015M on a quarterly basis; ■ Discontinue analysis for'DIPE, ETBE,TAME-an'd' AME-and.TBA; and ■ Continue status reporting on a semi=annual basis until MtBE concentrations at MW-2 ' warrant Site Closure or additional activities. 1 r E2C Remediation 3 ' Pr '��ect Number 1812BK26 October 3 2008 1.0 INTRODUCTION E2C Remediation (E2C) has completed First Quarter 2008 semi-annual groundwater monitoring activities for the Former Niagara Car Wash facility (Site). located at 1700 Stine Road in Bakersfield, California. In addition, this report presents the remediation status for the Site..This work was conducted in response to the State of California Regional Water Quality Control Board — Central Valley Region (RWQCB) letter dated August 26, 2003, and also in compliance with subsequent RWQCB directives, the latest of which is dated March 12, 2007. 1.1 Site Description rThe Site is:currently utilized as an operating car wash (Whitewater Car Wash) located in Bakersfield, California, at 1700 Stine Road between Stine Road and Hasti Acres Drive (see Figures_1_A.and. 1B for Site The Site encompasses approximately 1.7 acres and is located approximately 200 feet south of Ming Avenue. The Site is located in Section 11, Township 30 South, Range 27 East MDBM. ' Three (3) 12,000-gallon gasoline underground storage tanks (USTs) were located as shown on Figure 2 (Site Plan). The USTs were removed in April 2003. The fuel dispensers under the canopy area were removed, as well as the associated piping. One (1) 2,000-gallon waste oil UST is still located at the Site as shown on Figure 2. 1.2 Site Hydrogeology ' Regionally, the depth to groundwater had been estimated at approximately 190 feet ,bgs according to the 1996 Water Supply Report published by the Kern County Water .Agency. During March 2003 drilling activities, first encountered groundwater was found at a depth of ' approximately 163 feet bgs. In July 2005 groundwater was encountered at approximately 170 feet bgs. ' The surrounding area well survey identified four (4) production wells within a 2,500-foot radius of the Site..,All of these wells were noted to be operating during a field reconnaissance. The Stine Canal (irrigation and runoff) traverses the Site from northeast to southwest between the carwash building and Stine Road. The canal continues beneath the Site as a concrete pipe culvert which extends from north of Ming Avenue to the southern boundary of the Site. The canal is an unlined channel to the south of the Site. Water generally flows in the.canal on a year-round basis. 1.3 Site History A detailed Site History was discussed in the June 17, 2003 report, `Site Characterization Report of Findings, Report of Surrounding Area Well Survey, SVE System Installation and Pilot Test ' Report of Findings & Workplan to Implement Remedial Action, Former Niagara Car Wash, 1701 Stine Road, Bakersfield, California'(1 RAP). In March 2003,. E2C installed .one (1) groundwater monitoring well to assess groundwater conditions at the Site. In addition, six (6) VE wells .were installed and two (2) 40-foot soil borings were advanced on either side of the dispenser islands. Upon completion of the well installations, the remediation wells were plumbed to a manifold in the equipment pad area. This work was reported in the Site Characterization Report of Findings, dated June 17, 2003. In a letter, dated August 26, 2003, the RWQCB requested additional groundwater characterization. ' E2C Remediation 4 ' Pr oiect Number 1 8128 K 26 Oc tober 3 2 0 08 Groundwater monitoring wells MW-2 and MW-3 were.installed during the week of September 28, 2003, after which the wells were developed. Initial groundwater monitoring/sampling was conducted at the new wells in October 2003 and that data was reported in the Fourth Quarter 2003 Groundwater Monitoring Report, dated February 1, 2004, In May 2005, vapor extraction well (VE) VE-FD was installed at the Site, as approved by the ' RWQCB in a letter dated March 15, 2005. Installation of the well was reported in the following document: First Quarter 2005 Groundwater Monitoring Report, Second Quarter 2005 Groundwater Monitoring Report, Third Quarter 2005 Groundwater Monitoring Report, and Remediation Status Report, Former Niagara Carwash, 1701 Stine Road, Bakersfield, California, . dated September 5, 2005. ' In June 2006, (as reported in E2C's Second Quarter 2006 Groundwater Monitoring Report, Third Quarter 2006 Groundwater Monitoring Report, Additional Assessment Report of Findings and Remediation Status Report, dated November 28, 2006) E2C conducted soil vapor extraction activities to assess whether an unidentified source of fuel constituents were present at the Site. During the testing, the low vapor influent concentrations reported during the additional assessment testing (consisting of,an 8-hour continuous test) compare closely.to the influent concentrations reported at remedial system shutdown in August 2004. These low concentrations. indicate the presence of very minor residual fuel constituent impact in the vadose zone. Since the radius of influence at VE-FD is at least 105 feet, the additional assessment testing demonstrated that no significant fuel constituent mass is present within the radius of influence of VE-FD. If,significant residual fuel constituents were present in the vadose zone beneath the ' former fuel dispensers, or in the vicinity of the former USTs, reported influent concentrations would have reflected this and resulted in higher influent concentrations that increased throughout the duration of the test. In May 2007, (as reported in E2C's Residual Mass Assessment Report of Findings, Human Health Risk Assessment and Request for Site Case Closure, dated June 11, 2007) E2C ' conducted soil vapor extraction activities for an assessment of residual fuel and to perform a human health. risk assessment. Based on current concentrations of fuel constituents in the subsurface at the Site, non-detect in groundwater and very low in soil (35 ppmV at end of May ' '2007 testing), SVE remedial operations have reduced subsurface fuel constituents to levels that do not pose threats to human health or groundwater. In a letter, dated May 29, 2007, the RWQCB requested a reduction in the frequency of the monitoring to a semi-annual basis. ' 2.0 FIRST QUARTER 2008 SEMI-ANNUAL GROUNDWATER MONITORING E2C conducted First Quarter 2008 semi-annual groundwater-monitoring activities as described below. 2.1 Groundwater Elevation Monitoring The initial task performed was evaluating the wells for presence of free-product using a clear ' bailer. Free-product was not present in any well. The depth of freestanding groundwater was then measured to the nearest one-hundredth (0.01) of a foot using a Solinst water level indicator and an attached measuring tape. First Quarter 2008 semi-annual groundwater monitoring data are summarized in Table 1 and are presented with historical groundwater elevation data in Table 2. E2C Remediation 5 ' Project Number 1812BK26 October 3 2008 The groundwater flow direction for February 8, 2008 has been interpreted as west- southwesterly at a gradient of 0.0067 foot of vertical drop per foot of horizontal distance (ft/ft) (see Figure 3), a very flat gradient. The groundwater table elevation decreased an average of ' approximately 3.14 feet across.the Site since July 2007(see Table 2). Based on historical groundwater flow directions interpreted at the Site, it does not appear that recharge or discharge from the Stine Canal control the groundwater flow direction beneath the Site. This is likely due to the depth (156 feet bgs or greater) at which groundwater occurs beneath the Site. Therefore, groundwater flow beneath the Site may be regionally controlled ' and/or controlled by regional pumping southeast of the Site. , 2.2 Groundwater Sampling and Analysis Groundwater was purged at each monitoring well using a new disposable bailer. A minimum of three (30) casing volumes was removed from each well. prior to sampling groundwater. A casing volume is calculated by multiplying the height of the freestanding water column in the ' well by the cross-sectional area of the well casing. The temperature, pH and conductivity of the purged water were measured periodically to verify sufficient purging, as indicated by stable measurements on field instruments. When the measurements were within 10% of the previous ' readings the groundwater was considered stable for sampling (see Appendix'A for First Semi- annual 2008 groundwater purge data sheets). ' Each sample was collected using a new disposable bailer. Liquid in the bailer. was decanted into two 40-milliliter volatile organic analysis (VOA) vials. Each VOA was sealed using a tight fitting Teflon-lined screw cap. Care was taken so that no headspace or bubbles existed after sealing each VOA with the lid. All samples were labeled and documented on a Chain-of- Custody record immediately after sealing.. The samples were placed. into an iced cooler maintained at 4° Centigrade for transport to the analytical laboratory. Note: For this sampling event, the sample labeled MW-4 on the Chain-of-Custody Is a duplicate of the sample from ' MW-3. 2.2.1 Purge Water Recycling ' Groundwater sampling purge water was transported to Remedy Environmental.Services of Bakersfield, California for recycling (Appendix C contains copies of the non-hazardous purge water transport manifests and the recycling certificates). Groundwater Chemical Analyses Groundwater samples were transported to and analyzed at ProVera.Analytical Laboratories, ' Inc. (ProVera) (State Certification #2606) of Bakersfield, California in accordance with State guidelines and EPA protocols for the following: • Total Petroleum Hydrocarbons as gasoline (TPHg) using EPA Method 8015M; ' • The volatile aromatic compounds of benzene, toluene, ethylbenzene, and xylenes (total) (BTEX) using EPA Method 8260b; and • The five fuel oxygenates of methyl tertiary-butyl ether (MtBE), tertiary-butyl alcohol ' (TBA; a.k.a. tert-butanol), di-isopropyl ether (DIPE), ethyl-tertiary-butyl ether (ETBE), and tertiary amyl methyl ether (TAME) using EPA Method 8260b. ' Note: In a letter, dated February 9, 2006, the RWQCB directed the discontinuation of annual analysis of groundwater samples using EPA Method 8260b full-scan. In a letter, dated May 29, 2007, the RWQCB requested a reduction in the frequency of monitoring to a semi-annual basis.

The February 8, 2008 groundwater analytical data are presented in Table 1, are presented with historical analytical data in Table 3, and are summarized following: • BTEX compounds were reported as non-detect at all three (3) wells; ' • TPHg was reported as non-detect at all three (3).wells', • MtBE was reported at one (1) well (MW-2) at a concentration of 219.µg/L; and • TAME, TBA, DIPE, and ETBE were reported as non-detect at all three (3) wells. 2.2.4 Quality Control Samples The duplicate sample collected from well MW-3'was reported to contain similar or identical ' concentrations of COCs as the primary sample from that well. The trip blank.was reported as non-detect for any of the COCs at their respective detection limits, and the laboratory control samples all had recoveries within acceptable ranges. These results indicated that the analytical ' data are usable and are of adequate quality and reproducibility to satisfy data validity, requirements. 2.3 AB 2886 Compliance Groundwater analytical data for this quarter have been uploaded to the GeoTracker database in accordance'with State of California Assembly Bill 2886 (AB 2886). Groundwater elevation data ' have also been uploaded to the database. Finally, a copy of this status report has also been uploaded to the database. Appendix D contains copies of the available upload confirmation reports through the First Quarter 2008 semi-annual event. Any upload confirmation reports not ' included in this report will be included in the next semi-annual status report. 2.4 Discussion of Groundwater Monitoring Data Based on the groundwater analytical data from the First Quarter.2008 semi-annual event, groundwater beneath the Site is no longer impacted with fuel constituent COCs from past activities, except for a reoccurrence of MtBE at 21.9 gg/L in MW-2. Historically, the principal impact to groundwater was by extremely low ,concentrations of MtBE (the only.COC to have been reported since October•10, 2003). MtBE has been reported as non-detect at MW-1 since July 2004 and at MW-3 since October.2004. Throughout.that time, the groundwater table elevation fell and rose as much as four (4) feet. Generally, when the groundwater elevation rises it will bring groundwater into contact with residual fuel mass, if present, in the 'smear zone' and dissolved-phase concentrations will increase. Therefore, it'is unlikely that any significant fuel-hydrocarbon mass remains beneath the Site.. MtBE was detected at MW-2 in July 2007 at a concentration of 100 gg/L and at 219 gg/L in ' February 2008. The reoccurrence of MtBE at MW-2 is unclear, as MtBE had not been reported at that well for ten (10) quarters. E2C will evaluate the laboratory analytical data generated from the next sampling event to determine if additional actions, if any, are warranted. ' Note: DIPE, ETBE, TAME and TBA have all been reported as non-detect at all.three (3) Site wells since they were installed in 2003. These analysis should be discontinued. 1 ' E2C Remediation 7 Proiect Number 1812BK26 October 3.2008 ' 3.0 REMED/ATION STATUS REPORT Remedial operations at the Site were previously conducted utilizing a vapor extraction system ' (VES). To date, six (6) vapor extraction (VE) wells have been installed at the-Site. Two (2) of the VE wells (VES-AD and VES-BD) are screened deep (approximately 75 to 110 feet bgs), three (3) (VES-AS, VES-BS and VE-FD) are screened shallow (approximately 10 to 75 feet ' bgs) and one (1) (VES-C).is screened at medium depth (approximately 40 to 85 feet bgs). On May 14, 2004, the VES equipment (Baker'Furnace 250-CFM Thermal/catalytic Oxidizer with ' a propane-powered generator)'was brought on line. The system, prior to shutdown on August 31, 2004, was operating with wells VES-AS, VES-BS, and VES-C open and with VES-AD and VES-BD closed. This wellfield configuration yielded the highest influent concentration. During remedial system operations', the wellfield configuration was adjusted on a weekly basis to optimize the system effectiveness. Note: During the first ten'(10) days of system operation, the oxidizer shut down intermittently 1 due to low temperature or low pressure, so that only seven (7) days of actual runtime were achieved. This problem was repaired and the system operated continuously until August 31; 2004 when the SJVAPCD Startup, Inspection was conducted. During the inspection, the. SJVAPCD Inspector indicated that an .individual Permit To Operate (PTO) would also be required for the generator providing the electrical power. As such, the remediation system was shut down pending receipt of the additional PTO. It must be noted that the SJVAPCD originally permitted the site remediation equipment with a propane generator. A permit application for the generator was prepared and submitted to the SJVAPCD for their ' review and approval. On December 8, 2004, the SJVAPCD issued the PTO. Upon receipt of the PTO', E2C reviewed the permit conditions, which included a mandatory requirement for independent monthly testing of the generator emissions. This required testing.consisted of monthly Site visits to measure/test the generator emissions for an extensive suite of analytes. E2C solicited bids from several independent'testing contractors and determined that testing costs and propane costs would increase operational costs significantly, and that electrical service provided by PG&E would be substantially more cost-effective. Therefore, E2C applied to PG&E for installation of the permanent power supply. E2C received the contract documents from PG&E and found the cost to install permanent power to be excessive. However, on June. 15, 2006, E2C conducted additional assessment testing on extraction well VE-FD and the results of that testing demonstrated the presence of very minor fuel constituent impact to the vadose zone soils. In May 2007, E2C conducted an assessment of residual subsurface gasoline mass at the Site using SVE testing at existing VE wells in the area of the former underground storage tanks ' (USTs).- The work was conducted in accordance with a Workplan dated February 22,-2007, which was approved by the RWQCB by letter, dated March 12, 2007. ' Initially, all VE wells were individually tested to determine which well, or combination of wells, would yield the highest influent concentration(s). VES-C showed the highest concentrations during this testing; however, concentrations dropped at this well until at the end of testing 28 hours later, the concentration at VES-C was only 35 ppmV, a fuel hydrocarbon removal rate of jonly 2.1 pounds per day (Ibs/day). This indicates that continued operation of an SVE system would-extract soil vapors at less than 2.1 Ibs/day over any long-term period. Additionally, E2C Remediation 8 Project Number 1812BK26 October 3.2008 testing of the shallow and deep zones individually and collectively yielded very low (25-50 ppmV) influent concentrations. As such, the minor mass of fuel hydrocarbons remaining beneath the Site does not warrant continued remedial action. Groundwater is encountered at a minimum of 156 feet bgs. Based on current concentrations of fuel constituents in the subsurface at the Site, non-detect in groundwater (except for a reoccurrence of 100 µg/L of MtBE at MW-2) and very low in soil (35 ppmV at end of May 2007 testing), SVE remedial'operations have reduced subsurface fuel . ' constituents to levels that do not pose threats to human health or the environment. 3.1 Historical Remedial System Operations . 3.1.1 Thermal Oxidizer The remedial system consisted of vapor extraction using a Maker Furnace 250-CFM thermal ' oxidizer capable of adding a modular catalytic cell as concentrations.fall. The unit's minimum operating temperature in thermal mode was 1,400 deg. F. . This temperature was set 'to maximize vapor oxidation at reasonable electrical unit cost viea the propane-powered generator. The unit was equipped with a regenerative or PD type vapor extraction blower. For improved reliability and. safety, the valve controls, actuators, and components were controlled by relay logic switches. The unit was equipped with a water knockout pot, automatic air dilution capability, and a noise-reducing muffler. ' This equipment was designed to shut down and lock out in the event of a system malfunction. 9 Y The various safety features include high and low oxidizer bed temperatures, high and low ' blower pressure, high intake LEL, high and low air pressure, high and low exhaust temperature, and water knockout malfunction sensor. At least 99% destruction efficiency is stated in the manufacturer's specifications for the unit. Prior to shutdown, the remediation equipment was monitored on a weekly basis to perform routine maintenance, record oxidizer parameters (temperature, flow rate and operating hours) ' and measure influent'and effluent constituent concentrations. Although the oxidizer parameters were continuously recorded digitally. on 'a Zip disk, weekly monitoring of these parameters verifies accuracy of the measuring devices. Fuel constituent concentrations were also ' measured in the field using, a portable hydrogen flame ionization_detector (FID) and the data were used in applicable formulas to calculate the mass of fuel constituents removed on both a monthly and cumulative basis. Adjustments were continually made to the configuration of the unit to maximize vapor flow from the wellfield while maintaining the chamber temperature above 1,400 degrees. Fahrenheit (°F) as required in the SJVAPCD permit and below the manufacturer's recommended temperature limit of 1,850 OF in the stack. Note: Due to declining influent concentrations, a catalytic cell was added to the system on August 18, 2004. ' 3.2 Compliance with SJVAPCD Permit To Operate Compliance was demonstrated by monitoring of the influent and effluent streams with a FID or. PID instrument during regular system operations and weekly monitoring visits. From May 14 through May 24, 2004, the influent averaged 4,800 ppmv with 'zero''effluent, which equated to 100% destruction efficiency. Field records including sampling results, cumulative runtime, flow rate, and catalytic oxidizer temperature will be.maintained and retained for a minimum of two (2) ' E2C Remediation 9 Proiect Number 1812BK26 October 3.2008 ' years. When operating, system operation temperature was maintained at a minimum of 1,400 degrees Fahrenheit (°F) in the combustion chamber of the thermal oxidizer, and at a minimum of 600°F after the August 18, 2004 conversion to catalytic operation. 3.2.1 August 2004 Influent/Effluent Analytical Data On August 31, 2004, during the SJVAPCD Startup Inspection.test, TedlarO bag samples were ' collected from the influent and effluent sample ports. The samples were submitted to ProVera for analyses Total Petroleum Hydrocarbons as, gasoline (TPHg) using Modified EPA Method TO-3 and for volatile aromatics. (BTEX) using Modified EPA Method TO-15. The results are summarized following (the data was previously reported): ■ The influent BTEX components were reported at a total concentration of 64 ppmv, and the effluent concentration was reported as non-detect; and ' The influent TPHg were reported at a concentration of 500 ppmv, and the effluent concentration was reported as non-detect. Based on this data, the TPHg/BTEX destruction efficiency was 100%. 3.3 Fuel Hydrocarbon Mass Removal Rates ' Hydrocarbon removal rates were estimated using two different methods of calculation. The first method uses a straight-line extrapolation of influent measurements based on actual hourly run- time. Using this method, the mass of fuel constituents removed, from startup through August 31, 2004, was calculated at approximately 7,700 pounds (Ibs) (see Table 4) The second method uses the average influent over the average daily run-time per month. ' Using this method, the total mass of fuel constituents removed, from startup through August 31, 2004, was calculated at approximately 8,000 Ibs (see Table 5). ' 3.4 Discussion of Remedial Efficiency A significant quantity of fuel constituents were removed from startup through the end of August 2004. The fuel constituent removal rate showed a rapidly declining trend, from an initial rate of 1 nearly 600 Ibs/day at start up (May 14, 2004) to a rate at system shut down of 33 Ibs/day (see Table 5 graph). This declining rate suggested a rapid depletion of the `source' material. MtBE concentrations in groundwater were eliminated immediately. This operational data, combined with the recent additional assessment test data, indicated that remediation may be complete. In order to verify this E20, implemented the approved Pilot Test Workplan in May 2007 to assess whether an unidentified mass of fuel constituents exist near the.former UST pit. The results of ' the SVE testing in the former UST area demonstrated that benzene and MtBE were absent in the subsurface soils, and that the minor residual mass of fuel hydrocarbons in the vadose zone did not pose a risk to human health or the environment. 4.0 CONCLUSIONS Based on the site assessment work and groundwater monitoring data obtained at the Site to date, E2C concludes the following: ■ In February 2008 the groundwater flow direction was interpreted to be west- southwesterly at a gradient of 0.0067 ft/ft; ■ The average groundwater table elevation decreased 3.14 feet since July 2007. Recharge and or discharge from the Stine Canal, located along the eastern boundary of ' the Site, does not appear to control groundwater flow beneath the Site; E2C Remediation 10 ' Project Number 1812BK26 October 3 2008 ' In February 2008, groundwater samples were reported as non-detect for the fuel constituent COCs, except for the reported 219 gg/L of MtBE at MW-2. COCs have been ' reported as non-detect for fourteen (14) consecutive quarters at MW-1 and for thirteen (13) consecutive quarters at MW 73; • DIPE, ETBE, TAME and TBA have been reported as non-detect at all three (3) Site ' monitoring wells since they were installed in 2003; ■ During its limited operation period (May, 14, 2004 through August 31, 2004), between 7,700 Ibs and 8,000 Ibs of fuel constituents were removed from the subsurface at the ' Site; ■ Additional Assessment testing (consisting of an 8-hour continuous test) conducted on June 15, 2006 at vapor extraction point VE-FD demonstrated that no significant fuel ' constituent mass is present beneath the former fuel dispenser island, no benzene. or MtBE were present, and that only very minor fuel constituents might remain in the vadose zone; ' Additional Assessment testing (conducted between May 29, 2007 and May 31, 2007) at vapor extraction points VES-As, VES-Bs, VES-Ad, VES-Bd and VES-C demonstrated that no significant fuel constituent mass is present beneath the former UST area, no ' benzene or MtBE were present, and that only very minor fuel constituents might remain in the vadose zone; • An assessment of human health risk shows that limited residual fuel impact to medium- depth soils beneath the Site poses no threats to human health or the environment; and ' ■ Based on current concentrations of fuel constituents in the subsurface at the Site, non- detect in groundwater (excepting the reoccurrence of MtBE at MW-2) and very low in ' soil (35 ppmV at end of May 2007 testing) , SVE remedial operations have reduced subsurface fuel constituents to levels that do not pose threats to human health or the environment; and ' • Based on the above conclusions, it is E2C's professional opinion that further remediation at this Site is not necessary at this time; however, the MtBE concentration at MW-2 warrants continued monitoring to determine whether additional remedial efforts will be required. 5.0 RECOMMENDATION'S Based on the data presented.in this report and the above conclusions, E2C makes the following recommendations: ■ Continue groundwater monitoring on a semi-annual basis; ' ■ Analyze groundwater samples for BTEX and five fuel oxygenates (includes MtBE) using EPA Method 8260b and TPHg using EPA Method 8015M on a quarterly basis; ■ Discontinue analysis for DIPE, ETBE, TAME and TBA; and ' ■ Continue status reporting on a semi-annual basis until MtBE concentrations at MW-2 warrant Site Closure or additional activities. 1 E2C Remediation 11 ' October 3 2008 Project Number 1812BK26 6.0 LIMITATIONS,AND REPORT CERTIFICATION E2C performed this investigation.in.,accordance with the_generally alccepted standards,of care existing in California at.this time.
