Seattle, Washington 98134 UNDERGROUND TANK RELEASE, TEXACO SERVICE STATION, 240! OAK STREET, BAKERSFIELD, KERN COUNTY You submitted Fourth Quarter 2003 Groundwater Monitoring Report (Monitoring Report) dated 2 February 2004 and Site Assessment Report (Assessment Report) dated 20 February 2004. Delta Environmental Consultants, Inc., Monrovia (Delta) prepared the Monitoring and Assessment Reports. The Monitoring Report documents a quarterly groundwater monitoring event at the above-referenced site on 21 October 2003. The Assessment Report summarizes investigation conducted on 5 February 2004. Low concentrations of hydrocarbons not matching the diesel standard were detected in soil samples from borings lateral to the diesel and gasoline underground storage tanks (USTs). Analytes were not detected in samples collected during the fourth quarter 2003 groundwater monitoring event. Previous subsurface soil investigation and groundwater monitoring indicates that gasoline- and diesel- range petroleum hydrocarbons and the fuel oxygenate methyl tertiary butyl ether (MTBE) leaked at the subject facility degrading soil and that MTBE has degraded groundwater. We conclude that previous site investigations suggest that higher hydrocarbon concentrations may exist beneath the UST systems, but that the general absence of analytes detected during groundwater monitoring events and the very shallow-depth to-groundwater suggest that a significant mass of impacted soil is not-present beneath the UST systems. We do not request additional site investigation. Continue quarterly groundxvater monitoring during the first and second quarters of 2004. "Full scan" EPA Method 8260 and dissolved lead analyses may be discontinued. General minerals, nitrate and total Kjeldahl nitrogen analyses may also be discontinued provided that these analyses were conducted during the first quarter 2004. Summaries of the Monitoring and Assessment Reports and our comments follow. Monitoring Report Summary Blaine Tech Services, Inc., San Jose (Blaine Tech) collected groundwater samples from monitoring wells MW-1 through MW-5 on 21 October 2003. Depth-to-groundwater was measured from 19.89 to 24.57 feet below the tops of the casings (below TOC). Groundwater flow direction was toward the south with a water table slope of 0.006 feet per foot. California Environmental Protection Agency Recycled Paper Mr. Tony Palagyi - 2 - 30 March 2004 The samples were analyzed for total petroleum hydrocarbons as gasoline (TPH-g) by EPA Method 8015M, and for the analytes that typically comprise a "full scan" EPA 8260B analysis, including benzene, toluene, ethylbenzene, and xylenes (BTEX), MTBE, TBA (tertiary butyl alcohol), di-isopropyl ether (DIPE), ethyl tertiary butyl ether (ETBE), tertiary amyl methyl ether (TAME), 1,2-dichloroethane (1,2-DCA) and 1,2-dibromoethane (EDB) by EPA Method 8260B. The samples were also analyzed for dissolved lead by EPA Method 6010B. No analytes were detected in the samples. MTBE was detected in MW-3 at 17 p.g/L during the 18 June 2003 monitoring event. Other analytes were not detected during the 18 June 2003 event. MTBE was detected in MW-4 at 3.4 gg/L during the 3 September 2003 event. Other analytes were not detected during that event. Assessment Report Summary DeltaArilled_barings_SB=Lthro. ugh. SB:32o_ a_maximurn_depth_o f. approximately_3.1_feet bel~w-g.r-ound surface (bgs) using direct-push technology on 5 February 2004. Soil samples were collected at five-foot intervals. Delta logged soils encountered as poorly-graded sands with interbedded layers of sandy silt, silty sand, and clayed silt. Groundwater was encountered at approximately 23.5 feet bgs. Soil samples were analyzed in the laboratory for TPH-g and TPH-d by the DHS LUFT Method, and BTEX and the fuel oxygenates MTBE, TBA, TAME, D~E, ETBE, and ethanol by EPA Method 8260B. Analytes were not detected in SB-1. TPH-d was detected from 5.2 to 390 milligrams per kilogram (mg/kg) in four of five samples collected from SB-2. TPH-d was detected at 5.2 mg/kg in one of the five samples collected from SB-3. Other analytes were not detected in SB-2 and SB-3. Laboratory analytical reports note that chromatographic patterns for these detections do not .match the diesel standard. Delta suggests that TPH-d detections may result from natural compounds present in subsurface soils. Comments A release from the underground storage tank (UST) system has contaminated soil and degraded groundwater quality beneath the site. Previous soil and groundwater investigation was summarized in KHM Environmental Manag_eme__n.t_'s.' G~RA_.SP Site Assessment Report dated 9 May 2003. Low concentrations of TPH-g, TPH-d, MTBE, and TBA were detected in subsurface soils .at sampling point~ adjacent to the gasoline and diesel UST systems. Low concentrations of MTBE were detected in groundwater samples collected from on-site monitoring wells during previous groundwater monitoring events. With one exception, MTBE has not been detected in groundwater during the last two monitoring events. Low concentrations of TPH-d were also detected in soil samples collected from borings adjacent to the diesel and gasoline USTs during the 5 February 2004 investigation. Chromatographs for these detections do not match standard diesel chromatographs and TPH-g and other analytes were not detected. Delta suggests that the TPH-d detections result from natural compounds in subsurface soil. This hypothesis is possible, but should be verified by detections of the same natural compounds in background soil samples. We presently conclude that soil and groundwater investigations conducted lateral to the diesel and gasoline UST systems suggest the possibility of higher petroleum hydrocarbon concentrations beneath V:\UGTkProjectsklDW_filesk2004 C0rrespondencekCity of Bakersfield Cases\Texaco Sm OakSt GW-SA 3-04.doc Mr. Tony Palagyi - 3 - 30 March 2004 the systems. However, we also conclude that a significant mass of impacted soil beneath the UST systems is unlikely based on the shallow depth to groundwater (approximately 16 to 24 feet bgs) and the general absence of analytes detected during groundwater monitoring events. We do not request that you conduct additional site assessment. We request that you continue groundwater monitoring during the first and second quarters of 2004. Analysis by "full scan" EPA Method 8260 and dissolved lead may be discontinued since these analyses were conducted during the third and fourth quarters of 2003 and analytes were not detected. Continue analysis for TPH-g, TPH-d, BTEX, and the fuel oxygenates MTBE, TBA, DIPE, ETBE, and TAME. By our letter dated 6 January 2004, we requested that you conduct general minerals, nitrate, and total Kj eldahl nitrogen analyses during two non-consecutive quarters to characterize groundwater quality. You were ~6' c-ofidflct-thes~ analyses on samples from a~ least one upgradient and two d0wngradient monitoring wells. You conducted these analyses during the third quarter 2003. We requested that you conduct these analyses again during the first quarter 2004. Provided that you conducted these analyses during the first quarter 2004, these analyses may be discontinued. Please submit the First Quarter 2003 Groundwater Monitoring Report by 3 May 2004. As of the date of this letter, soil and groundwater sample analytical data have not been uploaded to Geotracker. We note that Delta has uploaded wellhead horizontal and vertical positioning data (GEO_XY and GEO_Z files), depth-to-water measurements (GEO_WELL files), and site maps (GEO_MAP files).

I I BLAINE TECH SERVICES, INC. ,METHODS AND PROCEDURES FOR THE ROUTINE MONITORING OF GROUNDWATER WELLS AT SHELL SITES Blaine Tech Services, Inc. performs environmental sampli_ng and' documentation as an independent third party. We specialize in groundwater monitoring assignments and intentionally limit the scope of our services to those bentered on the generation of objective information. To avoid conflicts of interest, Blaine Tech Services, Inc. personnel do not evaluate or interpret the information we collect. As a state licensed contractor (C-57 well drilling -water- 746684 ) performing strictly technical services, we do not make any professional recommendations and perform no consulting of any kind. SAMPLING PROCEDURES OVERVIEW SAFETY All groundwater monitoring assignments performed for Shell comply with, Shell's safety guidelines, .29 CFR 1910.120 and SB-198 Injury. and Illness Prevention Program (IIPP). All Field Technicians receive the full 40-hour 29CFR 1910.120 OSHA SARA HAZWOPER course, medical Clearance and on-the-job training prior to commencing any work on any Shell site. INSPECTION AND GAUGING Wells are inspected prior to evacuation and sampling. The condition of the wellhead is checked and noted according to a wellhead inspection checklist. Standard measurements include the depth to water (DTW) and the'total well depth (TD) obtained With industry standard electronic water level indicators that are graduated in increments of hundredths of a foot. The water in each well is inspeCted for the presence of immiscibles. When free product is suspected, its presence is confirmed using an electronic interface probe (e.g. MMC): No samples are collected from a well Containing over two-hundredths'of a .foot (0.02') of product. EVACUATION Depth to water measurements are collected by our personnel prior to purging and minimum purge volumes are calculated anew for each well based on the height of the water column and the diameter of the well. Expected purge Volumes are never less than three case volumes and are set at no less than four case volumes in some jurisdictions. Blaine Tech Services, Inc. Standard Methods & Procedures Shell Oil Products US Page 1 I I I I I I I I I I I I I I I I I I Well purging devices are selected on the basis of the'well diameter.and the total volume to be evacuated. In most cases the well will be purged using an electric' submersible pump (i.e. Grundfos) suspended near (but not touching) the bottom of the well.- PARAMETER STABILIZATION Well' purging completion standards include minimum purge volumes; but additionally require stabilization of specific groundwater parameters prior to sample collection. Typical groundwater parameters used to measure stability are electrical conductivity, pH, and temperature. Instrument readings are obtained at regular intervals during the evacuation process (no less than once per case volume). Stabilization standards for routine quarterly monitoring of fuel sites include the following: Temperature is considered to have stabilized when successive readings do not fluctuate more than +/- 1 degree Celsius. Electrical conductivit-y is considered stable when successive readings are within 10%. pH is considered to' be stable when successive readings remain constant or vary no more than 0.2 of a pH unit. DEWATERED WELLS Normal evacuation removes no less than three case volumes of water from the well. However, less water may be removed :in cases where the well dewaters and does not immediately recharge. MEASURING RECHARGE Upon completion of well purging, a depth to water measurement is collected and notated to ensure that the well has recharged to within 80% of its static, pre-purge level prior to sampling. Wells that do nOt immediately show 80% recharge or dewatered wells will be allowed a · minimum of 2 hours to recharge prior to sampling. The water level at time of sampling will be noted. PURGEWATER CONTAINMENT All non-hazardous purgewater evacuated from each groundwater monitoring well is Captured and contained in on-board storage tanks on the Sampling Vehicle and/or special water hauling trailers. Effluent from the decontamination of reusable apparatus (sounders, electric pumps and hoses etc.), consisting of groundwater combined with deionized water and non-phosphate soap, is also captured and pumped into effluent tanks. Non-hazardous purgewater is transported under standard Bill of Lading documentation to a Blaine Tech Services, Inc. facility before being transported to a Shell approved disposal facility. Bla/ne Tech Services, Inc. Stmadard Methods & ?rocsdures Shell O/1 Products US Page'2 I I I I I I I I I I ,I I I I I I I I I SAMPLE COLLECTION DEVICES All samples are collected using a stainless steel, Teflon Or disposable bailers. SAMPLE CONTAINERS Sample material is decanted directly from the sampling bailer into sample containers provided by the laboratory that will analyze the samples. The transfer of sample material from the bailer to the sample container conforms to specifications contained in the USEPA T.E.G.D. The type of sample container, matedal of construction, method of closure and filling requirements are specific to the intended analysis. Chemicals needed to preserve the sample material are commonly placed inside the sample containers by the laboratory or glassware vendor prior to 'delivery of the bottle to our personnel. The laboratory sets the number of replicate containers. TRIP BLANKS Trip Blanks', if requested, are taken to the site and kept inside the sample cooler for the duration of the event. They are turned over to the laboratory for analysis with the samples from that site. DUPLICATES Duplicates, if requested, may be collected at a site. The Field Technician uses their discretion in choosing the well at which the Duplicate is collected, typically one suspected of containing measurable contaminants. The Duplicate sample is labeled "DUP" and the time of collection is omitted from the COC, thus rendering the sample blind. SAMPLE STORAGE All sample containers are promptly placed in food grade ice chests for storage in the field and transport (direct or via our facility) to the designated analytical laboratory. These ice chests contain quantities of restaurant grade ice as a 'refrigerant material. The samples are maintained in either an ice chest or a refrigerator until relinquished into the custody of the la.boratory or laboratory courier. , DOCUMENTATION CONVENTIONS A label must be affixed to all sample containers. In most cases these labels are generated by our office personnel and are partially preprinted. Labels can also be hand written by our field personnel. The site is identified with the store number and 'site address, as is the particular groundwater well from which the sample is drawn (e.g. MWol, MW-2, S-1 etc.). The time and date of sample collection along with the initials of the person who collects the sample are handwritten onto the label. C/iain of Custody records are created using client specific preprinted forms following USEPA specifications. Blaine Tech Services, Inc. Standard Methods & Procedures Shell Oil Products US Page 3 I I I I I I I I I I I I I I I ! I I Bill of Lading records are contemporaneous records created in the field at the site whe~-e the non-hazardous purgewater is generated. Field Technicians use preprinted Bill of Lading forms. DECONTAMINATION All equipment is brought to the site in clean and serviceable condition and is cleaned after use in each well and before subsequent use in any other well. Equipment is decontaminated before leaving the site. The primary decontamination device is a commercial steam cleaner. The steam cleaner is de- tuned to function as a hot pressure washer that is then operated with high quality deionized water that is produced at our facility and stored onboard our sampling vehicle. Cleaning is facilitated by the use of proprietary fixtures and devices included in the patented workstation (U.S. Patent 5,535,775) that is incorporated in each sampling vehicle. The steam cleaner is used to deC°n Yeels, pumps and bailers. Any sensitive equipment or parts (i.e.. Dissolved Oxygen sensor membrane, water level indicator, etc.) that cannot be washed using the high pressure water, will be sprayed with a non- phosphate soap and deionized water solution and rinsed with.deionized water, DISSOLVED OXYGEN READINGS Dissolved Oxygen readings are taken pre- and/or post-purge using YSI meters (e.g. YSI Model 54, 58 or 95) or HACH field test kits. The YSI meters are equipped with a stirring device that enables them to collect accurate in-situ readings. The probe/stirring.deVices are modified to allow downhole measurements to be taken' from wells with diameters as Small as two inches. The probe and reel is decontaminated between wells as described above. The meter is calibrated between wells as per the instructions in .the operating manual. The probe and stirrer is lowered into the water column. The reading is allowed to stabilize prior to collection.' OXYIDATON REDUCTION POTENTIAL READINGS All readings are obtained with either Corning or Myron-L meters (e.g. Corning ORP-65 or a Myron-L UItrameter GP). The meter is cleaned between wells as described above. The meter is calibrated at the start of each day according to the instruction manual. FERROUS IRON MEASUREMENTS All field measurements are collected at time of sampling with a HACH test kit. Blairte Tech Services, Inc.
