This document documents the monitoring activities. In addition, the Remediation Status Report for the Site is presented. Summary of First Quarter 2004 Groundwater Monitoring On January 27, 2004, groundwater was monitored and sampled at the Site. The groundwater samples were chemically analyzed at a State of California-Certified analytical laboratory for the fuel hydrocarbon constituents of Total Petroleum Hydrocarbons as gasoline (TPHg), Total Petroleum Hydrocarbons as diesel (TPHd), a full-scan of volatile organic compounds (VOCs), which includes the volatile aromatic compounds of benzene, toluene, ethylbenzene, and xylenes (total) (BTEX), 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), the lead scavengers of 1,2-Dichloroethane (1,2-DCA) and 1,2-dibromoethane (EDB; a.k.a. ethylene dibromide), and dissolved lead. Finally, groundwater samples were also analyzed for inorganic parameters and metals. Summary of Remediation Status The SJV APCD permit has been issued for the Site and the Site remedial equipment has been contracted for construction. In addition, a Request for Modification to the Permit To Operate will be submitted to the SJVAPCD for their review on an expedited basis. The equipment should be completed in late March 2004 with subsequent installation and startup followed by long-term full- scale remediation. Conclusions Based on the site assessment work and groundwater monitoring data obtained at the Site to date, E2C concludes the following: · The groundwater flow direction and gradient beneath the Site is not known, however based on the configuration of the limited fuel hydrocarbon impact to groundwater, the flow direction is estimated as southerly; · Pumping from nearby water wells, specifically' CWS 158-01, and recharge from the Stine Canal could influence groundwater flow beneath the Site; · Principal fuel hydrocarbon impact to soils is in the Source Area, the former UST cluster; · Groundwater beneath the Site has been minimally impacted, based on low reported detections of fuel hydrocarbon compounds in groundwater samples; · MW-1 is located at/near the southwest leading edge of the groundwater plume and MW-3 is located near the southeast leading edge of the groundwater plume;'and . · Due to the low concentrations of dissolved-phase fuel hydrocarbons in groundwater, it may not be necessary to conduct additional groundwater characterization, as the existing downgradient wells are located at/near the leading edges of the groundwater plume. Recommendations Based on the data presented in this report and the above conclusions, E2C makes the following recommendations: · Continue groundwater monitoring and sampling on a quarterly basis; · Analyze groundwater samples for BTEX and five fuel oxygenates using EPA Method 8260B and for TPHg using EPA Method 8015M; · Analyze groundwater samples for 1 ,2-DCA and EDB for two additional quarters. If these compounds continue to be reported as non-detect, a recommendation will be made to discontinue these analyses; E2C Remediation 1 · I I I I I I I I I I I I I I I I I I I Proiect Number 1812BK03 March 3. 2004 a Discontinue the analysis for lead; · Discontinue the supplemental groundwater analyses; · Prepare and submit a Modification Request to the SJVAPCD for the existing Authority To Construct. The request will include a propane-fueled generator to provide electricity for the vapor extraction unit; · Mobilize the remedial equipment when construction is completed, construct the equipment compound enclosure, and implement full-scale remedial operations with weekly maintenance visits; and · If fuel hydrocarbon compounds increase in concentration and persist in groundwater at MW-3 and/or MW-1, this data will be evaluated and, if warranted, a Workplan for Additional Downgradient Groundwater Characterization with installation of additional well(s) may be submitted.

This report documents the groundwater monitoring activities and the results. In addition, the Remediation Status Report for the Site is presented. The work was performed in accordance with the State of California Regional Water Quality Control Board - Central Valley Region (RWQCB) letter dated August 26, 2003. 1.1 Site Description The Site is a currently operating car wash (Whitewater Car Wash) located in Bakersfield, California, at 1700 Stine Road between Stine Road and Hasti Acres Drive (see Figure 1 for Site Location Map). 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,OOO-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 have also been removed along with the associated piping. One (1) 2,OOO-gallon waste oil UST is still located at the Site as shown on Figure 2. The surrounding area is a mixed commercial and residential area along Stine Road and Hasti Acres Drive. The Stine Canal (irrigation and runoff) traverses the Site from northeast to southwest, between the carwash building and Stine Road. 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 September 2003 groundwater was encountered at approximately168 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 was observed to be flowing in the canal during a field reconnaissance. 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 & Work plan to Implement Remedial Action, Fonner 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 two (2) dual completion VE wells and one (1) single completion VE well were installed. Finally, two (2) 40-foot soil borings were advanced on either side of the dispenser islands. Upon completion of the well installations, trenches were excavated and the wells were plumbed to a manifold by the equipment area. Upon completion of plumbing, the trenches were backfilled and completed with concrete caps. This work was reported in the Site Characterization Report of Findings dated June 17, 2003. Based on their review of this work, the RWQCB requested additional groundwater characterization in a letter, dated August 26, 2003. EzC Remediation 3 · I I I I I I I I I I I I I I I I I I I Proiect Number 1812BK03 March 3 2004 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. 2.0 FIRST QUARTER 2004 GROUNDWATER MONITORING The following sections describe for the groundwater monitoring and sampling activities conducted by E2C Remediation (E2C) on January 22, 2004, which represented the First Quarter 2004. 2.1 Groundwater Elevations The initial task performed was checking the well 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. The equipment was washed with Alconox soap and double rinsed prior to each use. Currently, a licensed surveyor is being contracted to survey the wells to comply with AB2866. It is anticipated that surveying will be completed in the Second Quarter 2004. However, a southerly groundwater flow direction can be interpreted (see Figure 3A) based on the groundwater chemical data. First Quarter 2004 groundwater monitoring data are summarized in Table 1A and are summarized with historical groundwater elevation data in Table 2. 2.2 Groundwater Purging and Sampling Groundwater was purged at the monitoring well using a bailer. A minimum of 3 casing volumes was removed from the 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 indicated by stable measurements on field instruments. When the measurements were within 10% of each other, groundwater in the well was considered stable for sampling (see Appendix A for 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: The sample labeled MW-4 on the Chain-of-Custody is a duplicate of the sample from MW-3. 2.3 Groundwater Analyses Groundwater· samples were transported to and analyzed at Halcyon Laboratories (State Certification #1920) in accordance with State guidelines and EPA protocols for Total Petroleum Hydrocarbons as gasoline (TPHg) using EPA Method 8015M, volatile organic compounds (VOCs) using EPA Method 8260b full-scan, which include the volatile aromatics of benzene, toluene, ethyl benzene, and total xylenes (BTEX), 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 ether (TAME, and for the lead scavengers of 1,2-dichloroethane (1,2-DCA) and 1,2-dibromomethane (EDB; a.k.a. ethylene dibromide) using EPA Method 8260b. In addition, groundwater samples were analyzed at Columbia Analytical Services (State Certification #1364) for the following analyses: · General minerals, including nitrate; · Physical parameters of hardness, pH, and Total Dissolved Solids (TDS); · Total Kjeldahl Nitrogen (TKN); and · Total dissolved lead. E2C Remediation 4 · I I I I I I I I I I I I I I I I I I I ProiectNumber1812BK03 March 3. 2004 2.4 Summary of First Quarter 2004 Groundwater Analytical Data The current analytical are presented in tabular form in Table 1 and with historical analytical data in Table 3. The analytical laboratory report for the First Quarter 2004 is included as Appendix B. January 22, 2004 groundwater analytical data are summarized below: · 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 each of the three (3) monitoring wells with the maximum concentration (14 µg/L) reported at MW-3 (see Figure 4); · TAME, TBA, DIPE, and ETBE were reported as non-detect at all three (3) wells; · 1 ,2-DCA and EDB were reported as non-detect at all three (3) wells; · Tetrachloroethylene (a.k.a. perchloroethene) was reported at well MW-2 at a concentration of 1.5 µg/L and at well MW-3 at a concentration of 1.6 µg/L (1.7 µg/L in duplicate sample); · All other VOCs were reported as non-detect at all wells; and · General mineral, nitrate and TKN analyses revealed background levels for metals, moderately low hardness, neutral pH, low to moderate TDS and minimal TKN (see Table 4). 2.5 Discussion of Groundwater Analytical Data Based on the groundwater analytical data to date, groundwater beneath the Site has been minimally impacted. MW-1 is located at/near the southwest leading edge of the groundwater plume and MW-3 is located near the southeast leading edge of the groundwater plume. Due to the low concentrations of dissolved-phase fuel hydrocarbons in groundwater, it may not be necessary to conduct additional groundwater characterization, as the existing downgradient wells are located at/near the leading edges of the groundwater plume. 3.0 REMEDIATION STA TUS REPORT A SJV APCD Authority to Construct application has been prepared and submitted by E2C, and approved by SJV APCD for the remediation equipment. PG&E was contacted to obtain an estimate of costs and installation schedule to supply electrical power. Based on the PG&E cost estimate (>$20,000) and the estimate for time to complete (approximately six months at a minimum), E2C has explored other power supply options. Based on this research, E2C has opted to purchase a propane generator-powered thermal oxidizer. In addition, a Request for Modification to the Permit To Operate will be submitted to the SJVAPCD for their review on an expedited basis. In late November 2003 E2C was made aware of a new State Cleanup Fund (Fund) policy regarding equipment purchase and leasing. This policy requires pre-approval of costs for equipment purchase. E2C prepared and submitted the Request for Pre-Approval, which was approved by the Fund in January 2004. E2C has contracted Baker Furnace to construct the equipment. Equipment delivery is scheduled for late March 2004. Upon mobilization of the equipment to the Site, an equipment compound enclosure will be constructed followed by approximately 30 days of operation to allow the equipment to stabilize (i.e., 'work out the bugs') and to verify that the equipment will meet SJVAPCD permit conditions. The SJV APCD Startup Inspection will then be scheduled and conducted with subsequent reporting. Full-scale long-term remedial operations will then proceed. The Site will be visited on a weekly basis to maintain the equipment and record remedial system parameters. These parameters will be used to calculate the efficiency of the equipment, the fuel hydrocarbon removal rates, and the mass of fuel hydrocarbons removed.
