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) directives, the latest of which is dated October 29, 2008. ' Discussion of Groundwater Monitoring and Remedial Data Groundwater samples collected in the First Quarter 2009 were all reported as non-detect for the ' fuel hydrocarbon constituents of concern (COCs). During the site remediation period, fuel constituents were removed from the subsurface until only very low residual concentrations were present. 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. This declining rate suggested a rapid depletion of the ' `source' material. This operational data, combined with the June 2006 additional assessment test data, indicated that remediation appeared to be complete. In order to verify this, E2C, implemented an approved Pilot Test Workplan to assess whether a residual mass of fuel constituents was still present 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 the findings of very low residual soil-gas in soil (35 ppmV and less) and current concentrations (non-detect) in groundwater in the Third and Fourth ' Quarters 2008, SVE remedial operations appear to have reduced subsurface fuel constituents to levels that do not pose threats to human health or groundwater. ' At the request of the RWQCB, E2C submitted a Workplan to perform a soil-gas assessment. (SGA) on October 16, 2008 for installing three (3) soil gas investigation monitoring wells with collection of soil-gas samples to evaluate the potential for any remaining fuel hydrocarbon mass to pose an inhalation health risk at the Site. The SGA plan was approved by the RWWQCB by letter October 29, 2008. SGA sampling wells have been installed at the Site. Sampling of soil- gas at the installed SGA points will be conducted by the end of the Third Quarter 2009. Should ' soil-gas of the applicable fuel hydrocarbon compounds not be.detected at concentrations approaching or exceeding California Human Health Screening Levels (CHHSLs) a request for No Further Action (NFA) for this Site will be prepared and submitted. ' Conclusions Based on the site assessment work and groundwater monitoring data obtained at the Site to ' date, E2C concludes the following: ■ In the First Quarter 2009, the groundwater flow direction was interpreted to be east- southeasterly at a gradient of 0.0024 ft/ft, and the average groundwater table elevation ' increased approximately 0.25-foot; ■ In the First Quarter 2009, groundwater samples were reported as non-detect for the COCs. COCs have been reported as non-detect at July 27, 2004 at MW-1 since July ' 2004, at MW-2 since April 2008 and at MW-3 since October 2004; ' E2C Remediation 1 Proied Number 1812BK26 May 15.2009 ■ 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 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 was 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; and • An assessment of human health risk indicated that limited residual fuel impact to medium-depth soils beneath the Site posed no threats to human health or the environment. Recommendations ' Based on the data presented in this report and the above conclusions, E2C makes the following recommendations: • Continue groundwater monitoring and reporting on a quarterly basis as directed in the. ' RWQCB letter dated October 27, 2008; . • Implement the SGA and report the results; and ' • If the SGA finds that soil-gas for the applicable fuel hydrocarbons does not approach, or exceed the CHHSLs, then a Request for No Further Action for this Site will be submitted. E2C Remediation 2 Project Number 1812BK26 May 15,2009 1.0 INTRODUCTION E2C Remediation (E2C) has completed First Quarter 2009 quarterly 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) directives, the latest of which is dated October 29, .2008. ' 1.1 Site Description The 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 1A and 113 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. ' 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'(TRAP). 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 3 Proied Number 18128K26 May 15. 2009 . 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 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 near 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 the findings of very low residual soil-gas in soil (35 ppmV and less) and current concentrations, non-detect in groundwater in Third- and Fourth Quarters 2008, SVE remedial operations appear to have reduced subsurface fuel constituents to levels that do not pose threats to human health or groundwater. ' In a letter, dated October 27, 2008, the RWQCB requested an increase in the frequency of the monitoring from semi-annual to quarterly. At the request of the RWQCB, E2C submitted a Workplan to perform a soil-gas assessment (SGA) on October 16, 2008 for installing three (3) soil gas investigation monitoring wells with collection of soil-gas samples to evaluate the potential for any remaining fuel hydrocarbon mass to pose an inhalation health risk at the Site. The SGA plan was approved by the RWWQCB by letter October 29, 2008. SGA sampling wells have been installed at the Site. The SGA will be completed by the end of the Third Quarter 2009. Should soil-gas of the applicable fuel hydrocarbon compounds not be detected at concentrations approaching or exceeding California Human Health Screening Levels (CHHSLs) a request for No Further Action(NFA) for this Site will,be prepared and submitted. E2C Remediation 4 Project Number 1812BK26 May 15,2009 2.0 GROUNDWATER MONITORING E2C conducted First Quarter 2009 quarterly groundwater-monitoring activities on March 10, 2009. 2.1 First Quarter 2009 Groundwater Monitoring First Quarter 2009 groundwater monitoring was performed on March 10, 2009, as follows. ' 2.1.1 Groundwater Elevation Monitoring The initial task performed was to use a clear bailer to evaluate the wells for the presence of free-product. 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 2009 quarterly groundwater monitoring data are summarized in Table 1 and are presented with historical groundwater elevation data in Table 2. The groundwater flow direction for March 10, 2009 has been interpreted as east-southeasterly at a gradient of 0.0024 foot of vertical drop per foot of horizontal distance (ft/ft) (see Figure 3). 2.1.2 First Quarter 2009 Groundwater Sampling and Analysis 1 A new disposable bailer was used to purge groundwater at each'monitoring well. A minimum of three (3) casing volumes were '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 Quarter 2009 groundwater purge data sheets). Each sample was collected using a new disposable bailer. Liquid in the bailer was decanted ' into two (2) 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-2. ' All sampling equipment was decontaminated with and Alconox wash and a double-rinsed with P 9 . distilled water. ' 2.1.3 First Quarter 2009 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 fuel oxygenate methyl tertiary-butyl ether(MtBE) using EPA Method 8260b. tE2C Remediation 5 Proiect Number 1812BK26 May 15, 2009 2.1.4 Summary of First Quarter 2009 Groundwater Analytical Data The analytical laboratory report for the First Quarter 2009 quarterly monitoring event is included as Appendix B. The First Quarter 2009 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; and • MtBE was reported as non-detect at all three (3) wells. 2.2 Discussion of Groundwater Monitoring Data Groundwater samples collected in the First Quarter 2002 were all reported as non-detect for the COCs. 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, at MW-2 since April 2008 and at MW-3 since October 2004. MtBE was reported at low concentrations at MW-2, 100 µg/L in July 2007, at 219 µg/L in February,2008, and at 53.7 µg/L in April 2008. The occurrence of MtBE at MW-2 during those sampling events appears anomalous, as MtBE had not been reported as detectable at that well for the previous ten (10) quarters and since that time (non-detect in Third and Fourth Quarters 2008 and First Quarter 2009). 2.3 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). 2.4 Quality Control Samples ' The duplicate samples collected from well MW-2.were reported to contain similar or identical concentrations of COCs as the primary samples from that well. The trip blanks were 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. 2.5 CCR Compliance Groundwater analytical data for this quarter have been uploaded to the GeoTracker database pursuant to Title 23, Division 5, Chapter 30 of the California Code of Regulations (CCR). 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 2009 monitoring event. Any upload confirmation reports not included in this report will be included in the next quarterly status report. 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 ' E2C Remediation 6 Proied Number 18121IK21 May 15.2009 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 , Iremedial 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 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 addition, in May 2007, E2C assessed 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. 3.1 Historical Remedial System Operations ' 3.1.1 Therma/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 E2C Remediation 7 Project Number 1812BK26 May 15. 2009 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 iri applicable formulas to calculate the mass of fuel constituents removed on both a monthly and cumulative basis. ' Adjustments were continual) made to the configuration of the unit to maximize vapor flow from 1 Y 9 P 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 1 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, 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 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%. E2C Remediation 8 Proiect Number 1812BK26 May 15.2009 i 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. . i 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 Fuel constituents were removed from the subsurface until only very low residual concentrations were present. 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. This declining rate suggested a rapid depletion of the 'source' material. This operational data, combined with the June 2006 additional assessment test data, indicated that remediation appeared to be complete. In order to verify this, E2C, implemented an approved Pilot Test Workplan to assess whether a residual mass of fuel constituents was still present 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 in Third and Fourth Quarters 2008 and very low in soil (35 ppmV at end of May 2007 testing), SVE remedial operations appear to have I reduced subsurface fuel constituents to levels that do not pose threats to human health or groundwater. 4.0 CONCLUSIONS Based on the site assessment work and groundwater monitoring data obtained at the Site to. . i date, E2C concludes the following: ■ In the First Quarter 2009, the groundwater flow direction was interpreted to be east- southeasterly at a gradient of 0.0024 ft/ft, and the average groundwater table elevation increased approximately 0.25 foot; _ ■ In the First Quarter 2009, groundwater samples were reported as non-detect for the COCs. COCs have been reported as non-detect at July 27, 2004 at MW-1 since July 2004, at MW-2 since April 2008 and at MW-3 since October 2004; ■ 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; ■ Additional Assessment testing 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; E2C Remediation 9 Proiect Number 1812BK26 May 15. 2009 ■ 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 was 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; and ■ . An assessment of human health risk indicated that limited residual fuel impact to medium-depth soils beneath the Site "posed no threats to human health or the environment. 5.0 RECOMMENDATIONS Based on the data presented in this report and the above conclusions, E2C makes the following recommendations: ■ Continue groundwater monitoring and reporting on a quarterly basis as directed in the RWQCB letter dated October 27, 2008; ■ Implement the SGA and report the results; and ■ If the SGA finds that soil-gas for the applicable fuel hydrocarbons does not approach, or exceed the CHHSLs, then a Request for No Further Action for this Site will be submitted.

In addition, this report presents the remediation status for the Site. This work was conductedtin response to the State of California Regional . ' Water Quality.Control Board _Central Valley Region (RWQCB) directives, the latest of which is dated October 29, 2008. Based on the results of these monitoring events, groundwater,was . reported as non-detect for all fuel hydrocarbon constituents of concern (COCs), E2C is ' recommending that the Site be considered for Case Closure, or No Further Action (NFA). Discussion of Groundwater Monitoring and Remedial Data . ' Groundwater samples collected in the Third and Fourth Quarters 2008 were all reported as non-detect for the COCs. ' During the site remediation period, fuel constituents were removed from the subsurface until only very low residual concentrations were present. 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 lbs/day. This declining rate suggested a rapid depletion of the `source' material. This operational data, combined with the June 2006 additional`assessment test data, indicated that remediation appeared to be complete. In order to verify this, E2C, implemented an approved Pilot Test Workplan to assess whether a residual mass of fuel constituents was still present 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 the findings of very low residual soil-gas in soil (35 ' ppmV and less) and'current concentrations, non-detect in groundwater in Third and' Fourth Quarters 2008, SVE remedial operations appear to have reduced subsurface fuel constituents to levels that do not pose threats to human health or groundwater. At the request of the RWQCB, E2C submitted a Workplan to perform a soil-gas assessment (SGA) on October 16, 2008,for installing three (3) soil gas investigation monitoring wells with ' collection of soil-gas samples to evaluate the potential for any remaining fuel hydrocarbon mass to pose an inhalation health risk at the Site. The SGA plan was,approved by the RWWQCB by letter October 29, 2008. The SGA has been tentatively scheduled for implementation the week ' of December 9, 2008. Should soil-gas of the applicable fuel.hydrocarbon compounds not be detected at concentrations approaching or exceeding California Human .Health Screening Levels (CHHSLs) and/or San Francisco Bay Regional Water Board Environmental Screening ' Levels (ESLs), a request for ,Nb Further Action (NFA) for this Site will be prepared and submitted. 1 E2C Remediation 1 Proiect Number 1812BK26 December 2.2008 i 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 2008, the groundwater flow direction was interpreted to be ' southeasterly at a gradient of 0.0029 foot of vertical drop per'foot of horizontal distance (ft/ft), and the average groundwater.table elevation decreased 5.73 feet; ■ In the Fourth Quarter 2008, the groundwater flow direction was interpreted to be east- ' southeasterly at a gradient of 0.0034 ft/ft, and the average groundwater table elevation decreased an additional-3.65 feet; ■ In both the Third Quarter 2008 and Fourth Quarter 2008, groundwater samples were reported as non-detect for the COCs. COCs have been reported as non-detect since ' July 27, 2004 at MW-1 and since October 7, 2004 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,-20'04 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 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 was 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; and ■ An assessment of human health risk indicated that limited residual fuel impact to medium-depth soils beneath the Site posed no threats to human health or the ' environment. Recommendations ' Based on the data presented in this report and the above conclusions, E2C makes the following recommendations: • Continue groundwater monitoring and reporting on a quarterly basis as directed in the RWQCB,letter dated October 27, 2008; • Implement the SGA and report the results; and ■ If the SGA finds that soil-gas for the applicable fuel hydrocarbons does not approach, or ' exceed the CHHSLs andlor ESLs, then a Request for No-Further Action for this Site will be submitted. 1 . E2C Remediation 2 Pro lect Number 1812BK26 December 2 2008 1.0 INTRODUCTION E2C Remediation (E2C) has completed Third Quarter 2008 and Fourth Quarter 2008 quarterly 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) directives, the latest'of which is dated October 29, 2008. ' 1.1 Site Description The 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 1A and 1B 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. ' 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 1 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'(IRAP). ` ' 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 3 Project Number 1812BK26 December2.2008 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 115, 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'residua. fuel and to perform a human health risk assessment. Based on the findings of very low residual soil-gas in soil (35 ppmV and less) and current concentrations, non-detect in groundwater in Third and Fourth Quarters 2008, SVE remedial operations appear to have reduced subsurface fuel constituents to levels that do not pose threats'to human health or groundwater. ' In a letter, dated October 27, 2008, the RWQCB requested an increase in the frequency of the monitoring from semi-annual to quarterly. At the request of the RWQCB, E2C submitted a Workplan to perform a soil-gas assessment (SGA) on October 16, 2008 for installing three (3) soil gas investigation monitoring wells with collection of soil-gas samples to evaluate the potential.for any remaining fuel hydrocarbon mass 1 to pose an,inhalation health risk at the Site. The SGA plan was approved by the RWWQCB by letter October 29, 2008._ The SGA has been tentatively,scheduled for implementation the week of December 9, 2008. Should soil-gas of the applicable fuel hydrocarbon compounds not be detected at concentrations approaching or exceeding California Human Health Screening ' Levels (CHHSLs) and/or San Francisco Bay Regional Water Board Environmental Screening Levels (ESLs), a request .for N!o Further Action, (NFA) for this Site will be prepared and submitted. E2C Remediation 4 Proje t Number 1812BK26 December 2.2008 2.0 GROUNDWATER MONITORING E2C conducted Third Quarter 2008 and Fourth Quarter 2008 quarterly groundwater-monitoring activities on August 5, 2008 and October 29, 2008, respectively. 2.1 Third Quarter 2008 Groundwater Monitoring Third Quarter 2008 groundwater monitoring was performed on August 5, 2008, as follows. 2.1.1 Groundwater Elevation Monitoring ' The initial task performed was to use a clear bailer to evaluate the wells for the presence of free-product. Free-product was not present in any well. The depth of freestanding groundwater t was then measured to the nearest one-hundredth (0.01) of a foot using a Solinst water level indicator and an attached measuring tape. Third Quarter 2008 quarterly groundwater monitoring data are summarized in Table 1A and are presented -with historical groundwater elevation data in Table 2. The groundwater flow direction for August 5, 2008.has been interpreted as southeaster) at a . Y gradient of 0.0029 foot of vertical drop per foot of horizontal distance (ft/ft).(see Figure 3A). ' 2.1.2 Third Quarter 2008 Groundwater Sampling and.Analysis A new disposable'bailer was used to purge groundwater at each monitoring well. A minimum of three (3) casing volumes were 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 2008 groundwater purge data sheets). Each sample was collected using a new disposable bailer. Liquid'.in the bailer was decanted into two (2) 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. All sampling equipment was decontaminated with and Alconox wash and a double-rinsed with distilled water. 2.1.3 Third Quarter 2008 Groundwater Chemical Analyses Groundwater samples were transported to and analyzed at Pro Vera Analytical Laboratories, I 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 1 E2C Remediation 5 Proiect Number 1812BK26 December2.2008 L ■ 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. 2.1.4 Summary of.Third Quarter 2008 Groundwater Analytical Data The analytical laboratory report for the Third Quarter 2008 quarterly monitoring event is included as Appendix B. The Third Quarter 2008 groundwater analytical data are presented in Table 1A, 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 as non-detect at all three (3) wells; and ■ TAME, TBA, DIPE, and ETBE were reported as non-detect at all three (3) wells. ' 2.2 Fourth Quarter 2008 Groundwater Monitoring Fourth Quarter 2008 groundwater,monitoring was performed on August 5, 2008, as follows. 2.2.1 Fourth Quarter 2008 Groundwater.Elevation Monitoring Groundwater Elevation Monitoring was performed as detailed in Section 2.1.1. Fourth Quarter 2008 quarterly groundwater monitoring data are summarized in Table 1 B and are presented with historical groundwater elevation data in Table 2. Free product was not reported at any site well, and the groundwater flow direction for October 29, 2008 has been interpreted as east-southeasterly at a gradient of 0.0034 ft/ft. 2.2.2 Fourth Quarter 2008 Groundwater Sampling and Analysis ' Groundwater sampling and analysis was conducted as detailed in Section 2.1.2 (see Appendix C for Fourth Quarter 2008 groundwater purge data sheets). Note: For this sampling event, the sample labeled MW-4 on the Chain-of-Custody is a duplicate of the sample from MW-3. 2.2.3 Fourth Quarter 2008 Groundwater Chemical Analyses ' Groundwater samples were transported and analyzed as detailed in Section 2.1.3 2.2.4 Summary of Fourth Quarter 2008 Groundwater Analytical Data The analytical laboratory report for.the. Fourth Quarter 2008 quarterly monitoring event is included as Appendix D. The Fourth Quarter 2008 groundwater analytical data are presented in Table 1 B, 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 as non-detect at all three (3) wells; and ■ TAME, TBA, DIPE, and ETBE were "reported as non-detect at all three (3) wells. 2.3 Discussion of Groundwater Monitoring Data Groundwater samples collected in the Third and Fourth Quarters 2008 were all reported as non-detect for the COCs. tE2C Remediation 6 Project Number 1812BK26 December 2.2008 L 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. MtBE was reported at low concentrations.at MW-2, 100 µg/L in July 2007, at 219.µg/L in February 2008, and at 53.7 µg/L in April 2008. The occurrence of MtBE at MW-2 during those sampling events appears I anomalous, as MtBE had not been reported as detectable at that well for the previous ten (10) quarters and in the Third and Fourth Quarters 2008, MtBE was non-detect at that well. ' 2.4 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). 2.5 Quality Control Samples ' The duplicate samples collected) from well MW-3 were reported to contain similar or identical concentrations of COCs as the primary samples from that well. The trip blanks were 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. 2.6 AB 2886 Compliance Groundwater analytical data for these quarters 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 Fourth Quarter 2008 monitoring event. Any upload confirmation reports not included in this report will be included in the next quarterly status report. 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 E2C Remediation 7 Project Number 1812BK26 December2.2008 Irequired 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 1 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 addition, 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. 3.1 Historical Remedial System,Operations t3.1.1 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 capability, 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.. E2C Remediation 8 ftiect Number 1812BK26 December2.2008 Prior,to shutdown, the remediailion 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 I measured in the field using a poitable 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 t 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. ' 3.2.1 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 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 1 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). 1 E2C Remediation t Project Number 1812BK26 December 2,2008 3.4 Discussion of Remedial Efficiency Fuel constituents were removed from the subsurface until only very low residual concentrations ' were present. 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. This declining rate suggested a rapid depletion of the `source' material. This operational data, combined with the June 2006 additional assessment test data, indicated that remediation appeared to be complete. In order to verify this, E2C, implemented an approved Pilot Test Workplan to assess whether a residual mass of fuel constituents was still present ' 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'in Third and Fourth Quarters 2008 and very low in soil (35 ppmV at end of May 2007 testing), SVE remedial operations appear to have reduced subsurface fuel constituents to levels'that do not pose threats to human health or groundwater. 4.0 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 2008, the groundwater flow direction, was interpreted to be southeasterly at a gradient of 0.0029 foot of vertical drop per foot of horizontal distance (ft/ft),,and the average groundwater table elevation decreased 5.73 feet; • In the Fourth Quarter 2008, the groundwater,flow direction was interpreted to be east- , southeasterly at a gradient of 0.0034 ft/ft, and the average groundwater table elevation decreased an additional 3..65 feet; ' In both the Third Quarter 2008 and Fourth Quarter 2008, groundwater samples were reported as non-detect for the COCs. ,COCs have been reported as non-detect since July 27, 2004 at MW-1 and since October-7, 2004 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 1 7,700 Ibs and 8,000 Ibs of fuel constituents were removed from the subsurface at the Site; ■ Additional Assessment testing 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; 1 ■ 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 was 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; and ' E2C Remediation 10 Proiect Number 1812BK26 December 2 2008 ■ An assessrnenf of human-:health risk indicated that limited'. imited residual fuel impact to medium-depth soils,..beneath the Site posed no. threats <.to human .health or the ' environment. 5:0 RECOMMENDATIONS Based on the datapresented in this,report and the above conclusions.
