The results for all the analytes in samples MYS160 and MYS161 have been validated and are all below the specified contract required detection limits (CRDLs). Samples MYS140 through MYS150 were filtered through a 0.50 ~m filter. Ail of the samples were received at the laboratory at a measured cooler temperature of 24°C. Since all of the samples were preserved adequately and received by the laboratory two to three days aftercollection,' ' ' *'f no .. adverse effect on data quality is expected. The laboratory analyzed all of the samples for arsenic, lead, selenium, .... and thallium by Thermo Jarr~ll Ash ICAP61E Trace Analyzer 'according to Method 200.7' in the CLP Inorganic SOW. The instrument detection limits .,:~'i ' r' (IDL) for ars'ehic~" iead,;'selentum,.and thallium were 5elow 'the CRDLs specified for these analytes in the"Inorgantd SOW.'~ The analytical results with qualifications are listed in Table lA.

The matrix spike recovery ,results for antimony and chromium in QC sample MYS156 did not meet .the 75-125% criteria for accuracy. The percent recovery and possible percent bias for each analyte are presented below and are based on an ideal recovery of 100%. :i ....

The results reported for antimony.and chromium in all of the samples may ? be biased low, and where non-d6tected, false negatives may .exist. ESAT-QA- 9A- 12267/23806M03 .RPT ' · According to the SOW (ILM03.0), when the pre-digestion.spike recovery results for ICP analytes (except silver) fall outside the control limits of 75-125%, a post-digestion spike must be performed for those elements that do not meet the specified criteria. Post- digestion spike recovery results of 101.9% and 107.3% were obtained for antimony and chromium, respectively, in QC samp!a MYS156. Since the post-digestion spike recoveries were acceptable, the low pre- digestion spike recovery results of 58.2% and 72.8% obtained for antimony and chromium, respectively may indicate poor laboratory technique or matrix effects which may interfere with accurate analysis, depressing the analytical result. C The absolute value cf the result (-15.7 #g/L) obtained for ~elenium in the initial analysis of sample MYS152 was above ~he CRDL of 5.0 ~g/L. The high absolute value of the negative resul~ obtained for selenium may be.due to the high concentration of iron (interferent), which is present in the sample at 453,000 ~g/L. The laboratory diluted the sample at a factor of 5 and performed a reanalysis. The result obtained for selenium in the reanalysis of sample MYS152 was non-detected. Consequently, the quantitation limit reported in Table lA for selenium in sample MYS152 was raised by the dilution factor. D. In the analysis of the field duplicate pairs, the following relative percent differences (RPDs) were obtained for the analytes listed below. MYS146 D1 MYS157 D2 MYS147 D1 MYS158 D2 Dissolved Total Metals Analyte RPD RPD Aluminum --- 117 Arsenic --- 117 Barium --- 107 Cadmium --- 117 Calcium - - - 59.0 Chromium --- 126 Iron 189 125 Lead --- 106 Magnesium --- 104 Manganese 23.0 124 Mercury --- 126 Potassium --- 86.1 Vanadium --- 117 Zinc 167 113 Aluminum was measured at 1400 ~g/L in field duplicate sample MYS146 but not detected in field duplicate sample MYS147. The analysis of field duplicate samples is a measure of both field and analytical precision. The results are expected to vary more than laboratory duplicates (±20 RPD or ±CRDL criteria for precision) since sampling variability is included in the measurement. The imprecision in the results of the analysis of the field duplicate ESAT-QA-9A-12267/23806M0~.R~T -~ ICF KAISI~R pair may be due to the sample matrix, high levels of solids in sample, poor sampling or laboratory technique, or method defects.

If yoU are a frequent .user of validated GC/MS 'data from ~he EPA Contract LaboratorY Program (CLP) in Region IX,'you will notice some differences in the reporting format for the Tentatively Identified Compounds ..(TICs)' reported for Y.0ur-s~mples. ~: In the past, Region IX data reviewers have transcribed the TIC results reported bY" the laboratory ont° a-'table (Table lC'), a~d have "assigned rankings '~(A, B, or C) for' the Probability that compound identification is correct. The transcription is very time .consuming and labor intensive, and the ranking very subjective. The reVieWers will now simply' include annotated copies 'of the TIC reporting forms submitted by the laboratories into the data validatio~ report. Reviewers will continue to evaluate the TICs-for spurious or mis-identified data, and will annotate the forms accordingly. We believe that the old method of reporting'TICs resulted in a large expense in time 'and money without 'contributing much "value added# to the report. I would welcome any comments or questions you might have on our new reporting format. Please feel free to call me at (415) 744- 1499.

(URS) to conduct a Site Inspection (SI) of BC Laboratories in Bakersfield, Kern County, California. · * BC Laboratories was identified as a potential hazardous waste site and entered into the Comprehensive Environmental Response, Compensation, and Liability Information .. System (CERCLIS) on August 5, 1991 (!). A Preliminary Assessment (PA)..wa~ pe, rformed ~'.: for the EPA on September 13, 1993 (2). The purpose.of.the PA was to re~ie.w..~ex~ting information on the site and its environs to. assess., the, threats' ff any, posed _to public health, welfare, or the environment, and to determine if further investigation under CERCLA/SARA is warranted. After reviewing the PA, the EPA decided that further .. investigation of BC Laboratories would be necessary to more completely evaluate the site using the EPA's Hazard Ranking System (HRS).criteria. The HRS assesses the relative threat associated with the actual or potential releases of hazardous substances from the site. The I-IRS is the primary method of determining a site's eligibility for placement on the EPA's National Priorities List (NPL). The NPL identifies sites at which the EPA may conduct remedial response actions. This SI report is the result of URS' recent investigation. 1.1 Apparent Problem BC Laboratories (BC) operated an analytical laboratory on the site property from 1977 to 1990 (2, 3). Analyses performed at BC included metals, plant tissues, potable water, plant nutrient, and soil characteristics (2, 3). Wastewater generated during laboratory activities was discharged to a septic tank located at the rear of the building. A seepage pit, located approximately 10 feet west of the septic tank, was excavated to contain final liquid products after undergoing a breakdown process in the septic tank (2, 3, 4). The unlined seepage pit was excavated to an approximate depth of 20 feet below ground surface (bgs) in sandy and gravelly geologic materials possessing moderately high hydraulic conductivity (5, 6, 7). Depth to the unconfined aquifer underlying the site has historically ranged from 35 to 150 feet bgs (8). The depth to groundwater in the unconfined aquifer at the time of a May 1995 sampling event was approximately 19 feet bgs (9). Recharge to ~' '~' URS Consultant~, Inc. ~ ..

The asphalt area also contains the 2-foot-diameter circular lid of the septic tank, a smaller-diameter circular lid of the seepage pit, and a 3- to 4-inch depression in the soil resulting from the hand-augured hole left from a soil sample that was collected by a BC consultant. The septic tank consisted of two partitions and was approximately 6 feet deep. The top of the septic tank was approximately 2 feet bgs. An underground pipe led from the septic tank to'the seepage pit, or leach field, located approximately 10 feet west of the septic tank. The seepage pit is approximately 20 feet deep, with a gravel surface and concrete-lined walls. The diameter of the bottom of the seepage pit is approximately 4 feet..The geologic material in the seepage pit area was sandy to the extent that the hole kept collapsing on itself as it was being excavated. Specific details of the installation of the front septic tank are not available. A grassy area, where a second septic tank was reportedly installed, is located at the front of the property adjacent to Pie..rce Road... The front, septic tank is believed to contain bathroom wastes only. A parking lot is located at the inortheastem portion ol; the s~i~e.''' The parking lot is the location of a former underground storage tank (UST) and is demarcated by a triangular-shaped raised asphalt surface (see Figure 2-2, Site Facility Map) (3). 2 3 Operational History The former'BC site ~was a ~,acant lot prior to 1974, when the property was developed a:s a soap manufacturirig facility by Mr. David Anders6n. (2, 21, 22). Two septic tanks were installed at the time of site development. The front septic tank was installed to receive regular bathroom wastes. The rear septic tank was installed for the purpose of receiving wastewater, caustic soda, and vegetable oils associated with the soap manufacturing operation (5, 22). =Permits outlining details of the installation of the tanks are not available (23, 24). The seepage pit extended to a depth of approximately 20 feet bgs with a diameter of 4 feet in coarse-grained unconsolidated geologic material '(5). When soap manufacturing ceased to be profitable, Mr. Anderson began a business engaged in building aircraft vacuum stainless-steel tanks (5). After approximately 2 years of on-site operations, Mr. Anderson sold the property to Mr. Eglin in 1977. Mr. Eglin is the current owner of the property,.and he moved BC to.its current address at 4100 Atlas Court in Bakersfield in 1990 (2, 3, 5, 20). The BC facility initially conducted general agricultural chemical testing, performing plant tissue analysis for nitrogen, potassium, and phosphorUs 'content, as well as soil analysis and potable water analysis (2, 3). The BC site evolved .into a wet chemistry lab, reportedly performing only metal and inorganic analyses (2). According to the BC owner, no organic analyses were ever performed at the former BC site. The owner of BC operated another laboratory for organic analyses, located at 3014 Union Avenue in Bakersfield (3). Between 1977 and 1990, Kern Environmental Services (KES) transported all containerized wastes generated during laboratory operations, from the site (2). Hazardous waste manifests are available for the wastes transported off-site after 1985, when it became law to retain these documents (2). During BC's operational history, up to 12 drums containing hazardous waste were stored in the rear yard of the facility in 55-gallon .drums. The drums were placed upon a concrete pad, which was bermed to a height of approximately 2 inches on three sides (3). The drums were periodically removed from the premises by a licensed transporter to a permitted facility under a hazardous waste manifest. The wastes consisted of acids and caustics used in the laboratory analyses. After the chemical analyses were performed, these substances, including whatever, metals were detected, were neutralized before being placed in the drums (3)... Wastewater generated during laboratory activities was discharged into the rear septic tank (3). A 1,000-gallon UST, which contained refined p~troleum, was removed from the parking -. lot area of the site in March !.987 .(2, 3, 25). · It should be noted that petroleum products are excluded from the definition .of a hazardous substance, pollutant or contaminant under sections 101(14)and 104 (a)(2): of CERCLA.(26') 2.4 Regulatory Involvement 2.4.1 U.S. Environmental Protection Agency (EPA) BC is listed in the Resource Conservation and Recovery Information Service (RCRIS) database as of February' 21, 1995 as a small-quantity generator under the name BC 'Labs, Inc. (RCRA ID No. CAD981379977) (27). The notification date is listed as February 5, 1986. The approximate annual amount of hazardous waste, liquids and solids, generated at the Pierce Road facility, was appr. oximately 12,000 pounds. The solid wastes included soil remaining from sample analyses (28). A separate listing in the database shows BC Laboratories, Inc. (RCRA ID No. CAD982437899) as a large-quantity generator (27). The notification date for this site, located at 4100 Atlas Road in Bakersfield, is January 18, 1991. Neither site is listed as a RCRA treatment, storage, and'disposal facility (TSDF) in RCRIS. BC currently operates a laboratory at 4100 Atlas Road, which conducts both organic and inorganic analyses (28). Consultants, Inc. Page 7 I1' I~ Roy F. Weston, Inc. (Weston) conducted a Preliminary Assessment (PA) for the EPA on September 13, 1993. During the PA, no soil or groundwater samples were collected. An observed release of contaminants to soil or groundwater could not be documented. The site was evaluated based upon a potential to release metals to groundwater targets (2). 2.4.2California Environmental Protection Agency Department of Toxic Substances Control (Cai-EPA DTSC) The Cai-EPA DTSC Fresno District does not maintain files on BC (29). :. The site is not listed in the Cai-EPA DTSC active annual workplan sites (30). 2.4.3California'Regional Water Quality ContrOl Board, Central Vall'ey Regi~, (RWQCB) The RWQCB does not maintain file$ on the" former' BC site, and :has no regUlatory involvement with the site (31).'

The site file includes a 1989 hazardous materials list of chem!cals u.s..ed, and stored on. the premises. The f'de also includes information on the 1987 UST removal (32).. 2.4.6 San Joaquin Valley Unified Air Pollution ContrOl 'District (sJVUAPCD) ..

No contaminants were detected at the site, and the KCEHD issued closure to the tank. The site is not listed on the KCEHD "leaker's list" (25, 32, 34). GeoPlus Consulting Services (GeoPlus), Phase I and Phase II Investigations, 1991- on-site soil ~ampling was condu:cted as a result of the 1991 Phase I report, prepared by GeoPlus Consulting serVices (GeoPlus), which indicated that the septic tanks located on the site property may pose an environmental threat (35). A Phase II investigation was subsequently conducted..by Ge0P!.us' in Janua.ry 1992. One composite soil sample was collected a~t depths of 19 and 18 feet bgs..The sample location was between the ·septic ~'tank and the seepage, pit (see Figu~'~ 2-2, Site F~cility Map). The sample was analyzed for California Assessment Manual (CAM) metals, ignitability, reactivity, and corrosivity. Only arsenic, detected at 4.1 milligrams per kilogram (mg/Kg), was above the Cancer Risk Screening Concentration health-based benchmark of 0.33 mg/Kg (36). No other metal exceeded established benchmark values. No soil samples were collected to establish background concentrations for metals. The sampling event by GeoPlus' is insufficient to make any definitive statements regarding the absence or preSence of hazar~lous substances contamination of soil because only one composite soil sample was collected, no background samples were collected, and only one analysis Of the sample was conducted. No regulatory agency oversaw the sampling (6). 3.2 EPA Sampling 3'.2.1 Purpose and Description pf Sampling Event Under direction of the EPA, URS prepared a Field Sample Plan (FSP) to collect groundwater samples at the BC site. The FSP was reviewed by the EPA's Quality UR$ Consultant., Inc. Page 9 Assurance Management Section and the EPA Site Assessment Manager. The final FSP was approved by the EPA on July 17, 1995. The groundwater sampling effort was conducted by URS on July 19 and 20, 1995 to assess whether groundwater had been impacted by site activities; specifically, to assess whether heavy metal contaminants and organics in downgradient shallow groundwater exceed background concentrations. Eleven HydroPunch® groundwater samples were collected, including two equipment blanks (equipment rinsate samples), one field duplicate sample, and eight environmental samples (HP-1 to HP-8), one of which was a double volume sample to allow for laboratory Quality Control (QC) analyses (see Figure 3-1, Sample Location Map). The samples were analyzed for metals, filtered and unfiltered, according to the Contract Laboratory Program Analytical Services (CLPAS) Statement of Work (SOW) (ILM03.0), with no modifications. Samples were additionally analyzed according to CLPAS SOW (OLM02.0) for volatile organic analysis O/OAs). The groundwater: Samples were collected utilizing a cone penetrometer (CPT) direct-push method. No subsurface .. soil samples were collected at the groundwater sampling points. 3.2.2 Deviations from Sampling Plan Decontamination procedures for field equipment, specificall~ the 3/4-inch bailer, were not followed,' as a peristaltic pump was used to obtain the required sample volume. Instead of a bailer, dedicated teflon tubing was used to bring formation water directly into the sampling containers in order to avoid lengthy periods of time. in collecting the samples by using such a small bailer. Because dedicated tubing was used at each sampling location, no decontamination of equipment was necessary. The .equipment blank sample containers for VOA were filled with distilled water, rather than de-ionized water, as stated in the sample plan..The sample numbers are designated WER-01 and WER-02. The compounds detected in these samples included methylene chloride and acetone, which are also common laboratory contaminants.. 3.2.3 Discussion of Sample Results The samples were analyzed for metals, filtered and unfiltered, according to the CLPAS SOW (ILM03.0) with no modifications... The samples Were additionally 'analyzed according to CLPAS SOW (OLM02.0) for volatile organic analysis O/OAs). Selected results are presented in Tables 3.1 and 3-2. ..... URS Coneultant., Inc.'

URS Consultants, Ino. Page 13 Analytical results of the VOA analysis indicate that all analytes were non-detect. Several of the results were qualified as non-detect, and estimated "UJ" due to contamination in equipment blanks. Acetone and methylene chloride were found in equipment blank WER-01 at concentrations of 12 and 14 micrograms per liter (l~g/L), respectively, and in equipment blank WER-02 at concentrations of 11 and 31 I~g/L, respectively. The presence of acetone and methylene chloride in the samples is most likely attributable to the use of distilled Water, rather than de-ionized water, for the equipment blanks (12). Of the samples analyzed for filtered metals, arsenic, lead, selenium, and thallium were analyzed aCcording to Method 200.7 in the CLP Inorganic SOW. The instrument detection limits (IDI,s) for arsenic, lead, selenium, and thallium were below the Contract Reporting Detection Limits (CRDL:s). specified for these analytes in the inorganic SOW. The following 'results are estimated, 'are fl~gged "J,"' and include all results' above the IDL, but below the CRDL.- These results are considered qualitatively acceptable, but quantitatively unreliable due to uncertainties in the analytical precision near the'limit of detection. In the a~alysis" 0t~'fiel'd ~tiPii'cate Piiirs', relative` percent differences (RPDs) Viried from 59.0 percent to' 126 percent.. Aluminum, for example, was measur&d at' i',~100 llg/L in field sample WFHP-07-01, but was not detected in the duplicate sample WFHP-07-02. The m~isure of field dtipliCate samiSles is a measure of both field and analytical, precision. The imprecision in the result~ ~f th;" ana'iySis'of ihe field 'dupliCate pai? may be due to the sample matrix, high levels0f solids in'the sample, poor.sampling Or laboratory technique, O'r method defects~ The effect on the :quality of the data is not known (13). Antimony and chromium in all unfiltered samples are flagged "J." The matrix spike recovery results for antimony and chromium in Quality COntrol. (QC) sample WHP-06-01 did" r~0t meet'"ihe 75 Ko' 125 percent criteria for accuracy. Results above the IDL are considered quantitatively~ uncertain. The results reported for. antimony and chromium in all the samples maybe biased low, and where non-detected, false negatives may exist (13). The absolute value of the result (-15.7llg/L) obtained for selenium in the initial analysis of unfiltered sample WI-IP-02-01 was above the CRDL of 5.0 Ilg/L. The high absolute value of the negitive' result obtained for selenium may be due to the high concentration of iron (interferent), which is present in the sample at 453,000 Ilg/L. The laboratory diluted the sample at a factor of 5 and performed a reanalysis. The result obtained for selenium in the reanalysis of sample WHP-02-01 was non-detect. Consequently, the quantitation limit reported for selenium in that sample was raised by the dilution factor (13). -. URS Consultnnt., ino. Page 14 The filtered metals and VOCs results do not support groundwater contamination from on-site activities. Although no VOC$ or filtered metals were detected through laboratory analysis, the unf'dtered metal samples indicate that some contamination from site activities may be present in groundwater underlying the site. The most frequently occurring location for metal contamination is in the unfiltered background sample WHP-02-01, which was collected from the site property. Site-related activities or temporary structures, used in BC laboratory analysis, may have contributed to the higher concentrations found in WHP-02'-01. ' The background concentrations determined from the off-site location, WHP-01-01, may be a truer repres~.ntation of background metal concentrations.. There is also s~.me suspicion that metals are migrating onto the adjacent property, .as evidenced by dpwngradient' sample conc~en!rat!..o,~?s at sample locations WHP-05 and WHP-07-01.

It is the principal mechanism the EPA uses to place sites on the National Priorities List (NPL). URS has evaluated the HRS factors discussed below, which are relative to this site. 4.1 Sources of Contamination, URS has identified one potential source of contamination at the former BC site, consisting of contaminated soil in the vicinity of the septic tank and seepage pit.

GeoPlus. in December 1991,: at depths of 10 and 18 feet bgs ~6). 4.2 Groundwater Pathway 4.2.1 I-lydrogeol0gic Setting The BC Labs site is located within the San Joaquin Valley, the southern portion of the Central Valley of California. The Central Valley is a large, asymmetric trough bounded by granitic, metamorphic, and marine sedimentary rocks of pre-Tertiary age. The Central Valley is approximately 400 miles long, and averages approximately 50 miles wide. The trough has been filled with as much as 6 vertical miles of sediment in the San Joaquin · Valley.. The Kern River alluvial fan overlies the trough between the crystalline rocks of the Sierra Nevada and the marine rocks of the Coast Ranges The Kern River fan is the southernmost major alluvial fan built by streams that drain the west side of the Sierra Nevada Mountains. The marine rocks are at an average depth of 2,000 feet. The overlying continental deposits that comprise the groundwater reservoir consist of alluvial fan and lacustrine (lake) deposits (37). The continental deposits are subdivided into three lithologic units on the basis of grain size and sorting: a gravel and clay unit, a fine sand to clay unit, and a gravel to medium :'" '. URS Consultants, Ino. : Pa8e 16 sand unit (37). According to a geologic map of the Kern River alluvial fan area, the BC Lairs site is located within the gravel to medium sand unit (37). This unit consists of two separate deposits: one is of Sierra Nevada provenance and crops out along the east side of the valley, while the other unit is derived from the gravel and clay deposits of the Coast Range provenance and crops out along the northeast flank of the Elk Hills, located to the west of the site (37). The Sierra Nevada provenance fans are the best reservoir rock. In addition to the Sierra Nevada sediments, the lithologic unit that makes up the gravel to medium sand unit also consists of sediments of dissected uplands. The Sierra Nevada-. derived material consists of a basal gravel overlain by medium sand. Dissected upland- derived material is a heterogeneous deposit of sand and gravel with permeability between 10: to 104. Thickness of the gravel to medium sand unit is approximately 300 to 400 feet. ' In general, the gravel to medium sand unit contains unconfined water (37). There is a grpundwater divide that approximately underlies the Kern River. Kem'River water is the principal source of .recharge to the area (7, 37). Short-term infiltration tests made on canals in the alluvial fan area indicate that the average infiltration for a canal " segment (4.5 to 5.9 miles) .ranged between 10.2 and 28.8 percent, with an average rate of 25 percent (37). Water moves from the recharge mounds, which underlie the Kern River and the cataal.% ,to areas of he'4. vy groundwater withdrawals. .. The BC site is located on the upper portion of the Kern River alluvial fan, a high-energy dePositional environment that is both heterogeneous and anisotropic, displaying every grain size (7, 37, 38). The. lithology underlying the site, as obtained by a cone penetrometer boring during URS field sampling activities, is the following, from bottom to top:. a layer of sand to silty sand from 21.5 to 24 feet bgs; a layer of sand from 19.5 to · 21.5 feet bgs; a layer of sand to silty sand from 6 to 19.5 bgs; a layer of silty sand to sandy silt from 5 to 6 feet bgs; a layer of sandy silt to clayey silt from 2 to 5 feet bgs; and a layer of sensitive f'mes from 0 to 2 feet bgs (9). The lithology Underlying the area where the soil sample was collected by GeoPlus in 1991 has been described as coarse granular sand with some pebbles; rounded to subrounded grains; well sorted, unconsolidated, very loose; .~. dominantly quartz and feldspar; rock fragments; mica grains common; with porosity and permeability good to excellent (6). Groundwater underlying the site in the unconfined aquifer'was approximately 19 feet bgs at the time of the sampling event in July 1995; however, recent historic groundwater levels range from 35 to 150 feet bgs (8, 91 25). The groundwater gradient in the site area is · '~ ' UIIS Consultants, Inc. Page 17 0.0087 foot/feet to the southwest (39). The annual net precipitation is 0.8154 inch in the Bakersfield area (40). 4.2.2 Groundwater Targets Drinking water used by Bakersfield is derived mostly from groundwater. The following is a description of groundwater purveyors in the Bakersfield area and the population they serve. The City of Bakersfield operates 40 to 45 wells that serve 100 percent of the drinking water to approximately 60,000 people. The City of Bakersfield wells have not revealed contamination from metals, although occasionally,' refined oil products such as xylene have been detected (15). · The Oildale Mutual Water Company (OMWC) operates 12 groundw, ater wells to ser~e approximately 20,000 people. The wells contribute 5 percent or less to the total water :.supply, except in drought conditions, when OMWC serves 50 percefit' groundwatei-i The ,..:. majority of water delivered to OMWC Customers is derived from surface water pfO~,ided ,.by Kern County Water Agency (KCWA). The OMWC wells have been drilled to 600 to 1,000 feet, with perforations at 200 to 500 feet bgs. Several OMWC wells have gone out of .. service due to oil tastes, probably attributable to nearby oil fields. Two OMwC "wells contain low levels of tetrachlorethylene (PCE) most likely attributable to one of Several dry cleaners (16). ·: The California Water Service (CWS) owns approximately 130 Working groundwater wells · and serves, approximately 56,000 connections. Approximately 80 percent of the CWS system is supplied by groundwater. The remaining 20 Percent of the 'water is derived from the KCWA. The average depth of CWS wells is between 175 to 200 feet bgs. All CWS draw from the same aquifer with pumping rates ranging from 800 to l',200'gpm. Two CWS wells were closed approximately 7 years ago due to petroleum contamination, but were put back into service after a year. The wells are located approximately 1 mile from the BC site (19). Well 151-01 is located approximately 0.40 mile downgradient of the site (19). This well has a pumpage rate of 800 gpm and operates about 12 hours per · ' day during the winter season. The well has not been shut down within the last 10 years. Water quality data for well 151-01 as determined by sampling in 1992 indicated no contamination from metals (41). Well 192-01, a 5- to 6-year-old well, is located /: approximately '0.60 mile' south of the site (19). The pumpage rate is 930 gpm, and operates 24 hours per day during the summer season. This well exhibits a musky odor, " URS ©0neultinte, Ine, Page 18 but there is no contamination in that well (14). Water quality data for well 192-01 as determined by sampling in 1990 indicated no contamination from metals (42). The North of the River Municipal Water District (NORMWD) has two wells that supply approximately 30,000 people. The wells are used as standby wells as NORMWD usually uses surface water, except in drought conditions, when approximately 25 percent groundwater is used. Mercury contamination in one of the NORMWD wells has been cleaned up (17). The Vaughn Water Company provides approximately 4,240 connections with 100 percent groundwater (18). Additional private domestic wells serve an approximate population of 4,450 within 4 miles of the site (43, 44, 45, 46, 47). 4.2.3 Groundwater Pathway Cogclusions An observed release't0"g~oUndw:i~er has not been 'dOcumented at th~ former BC sitS.

The c:mal is a diversionary channel from the Kern River, "which is~located appr6×imately 1.5 miles to. the east of the site (3, 10). The Kern Rive~- drains the Southern Sierra Nevada, located to the east of the' Central Valley. The cana[ is used for groundwater recharge and irrigation (7). The canal flows from east to west through approximately 9 miles in urban Bakersfield, and then proceedS to Po,s6 Creek where it enters that water. The distance to Poso Creek from the Kern River diversion is approximately 30 miles (48). The 2-year, 24- hour precipitation f'6r' dae' Bakergfield area is apPrc~ximately 1.1 inches (49).' URS ©onsultnntn, Ino. .' Pase 19 4.3.2 Surface Water Targets There are no drinking water intakes or sensitive aquatic species located within 15 miles downstream of the site in the canal (50). There is not a permanent fish population in the canal. When the canal is activated by water from the Kern River, it is possible that fish would migrate from the Kern River, but a fish population would not be established. A small amount of fish may be caught in the canal, but the amount would range from 0 to 100 pounds of fish.' Fish species that could potentially be found in the canal include catfish, blue gill, crappie, bass and carp (51). 4.3.3 Surface Water Pathway ConcluSions " · An observed release to surface water from ~the former BC Site h~is not be'eh documented. No surface water or sediment samples have been collected for ana!Ysis; There is no documentation of a discharge of contaminants .to..the canal from the former BC site, as the hazardous substances are not .available to .re .surface ,.w. ater pathway. Surface water flows toward the ,south-southeast (rear). p.o.~ion of the site, and may be captured in the " drum storage .area (3).

Potentially contaminated soil in the rear yard area at the location of the septic tank and seepage pit is covered by at least 2 feet of soil overlain by asphalt. Arsenic was detected at concentrations exceeding established health-based benchmarks at depths of 10 and 18 feet bgs; however, arsenic at 4.1 mg/Kg is within the range of normal background levels for the Bakersfield area, according to a representative of the United States Geological Survey (USGS) .(6, 52).

The site occupies 0.753 acre in a light industrial area.. The site consists of a 5,000-square-foot building, a rear unfenced yard paved with asphalt, and a concrete drum storage area.' A septic tank' and seepage pit (leach field) are also present in the subsurface under the aspha!t cover. The site is bordered by the Calloway Canal (canal) to the east, Pierce Road to the west, and the California Highway Patrol (CHP) to the south. The former BC site is curren, tly operated by Continental Labor Resources, Inc., and employees three to four workers. BC operated a laboratory for inorganic analyses at the site from 1977 until 1990. During that time, wastewater generated during laboratory activities was discharged to a rear septic tank which led to a seepage pit 0each field). Results of a December 1991 soil sampling effort initiated by the BC owner, Mr. Joseph Eglin, revealed the presence of arsenic at a concentration of 4.1 milligrams per kilogram (mg/Kg) in a composite soil sample collected at depths of 10 and 18 feet below ground surface (bgs). This level of contamination exceeds the Cancer Risk Screening health-based benchmark of 0.33 mg/Kg; however, 4.1 mg/Kg is within the range of normal background levels, according to a representative from the United States Geological Survey. No background samples were collected for comparison. The groundwater sampling effort was conducted by URS on July 19 and 20, 1995 to assess whether groundwater had been impacted by site activities; specifically, to assess whether heavy metal contaminants and organics in downgradient shallow-groundwater exceed background concentrations. Analytical results of the July 1995 URS grab groundwater sampling effort did not indicate the presence of elevated concentrations of metals or Volatile Organic Compounds (VOCs) in filtered groundwater samples. The samples were collected on-site as well as off-site for background and downgradient locations using the direct push method. An observed release of metals and VOCs have not been documented, although there is some indication that elevated concentrations of metals are present on-site, as determined by a review of analytical results from the unfiltered groundwater samples. The results of the unfiltered samples may have been artificially inflated due to the turbid conditions caused by the direct-push method of groundwater collection. ; URS C~onsult~nte, Ino, Page 24 The following are pertinent HRS factors associated with the site: · Groundwater sampling by URS in July 1995 did not reveal elevated levels of" contaminants in groundwater underlying the site. ~. · Analysis of groundwater in downgradient municipal wells has not revealed elevated levels of. contaminants associated with the site · Groundwater wells within 4 miles of '~he §ite '~provide drinking 'wate~ to" ................ approximately 182,000 people in Bakersfield ............ .. · Surface water is not used for drinking, commercial .fishing, or sensiti~ species habitat within 15 miles downstream of the site. · The s{t~'g~i'ff~'~&' iS;"~ovei'~'d with asph'~il~pa~;em~'nt;"':c06cr'~te,"arid buildings, except for a small grassy area in the front of the ;'property.,...

Kern County has jurisdiction when a UST is removed; however, there was no UST investigation conducted by KCEHD. The site is not listed on the KCEHD "leaker's list." The UST was removed and never went to further characterization. Soil samples collected at the time of the UST removal did not reveal contamination. KCEHD will photocopy their file on BC Laboratories and send it to URS. Groundwater is located at 35 feet below ground surface (bgs) at the site. 1/~/95: Ms. Von Sydow stated that the section in which BC is located is the most contaminated in Kern County. Approximately 140 sites in the area have environmental problems. There are at least 3 facilities in the Township/Range section in which BC is located that have monitoring wells due to tank leaks or other problems; Union Carbide on Pierce Street, Davis Oil on Sillect Street, and San Joaquin Drum on Gilmore. San Joaquin Drum is a State Superfund site and is located downgradient of the BC labs site. The groundwater flow direction is to the southwest The San $oaquin Drum site is contaminated with hydrocarbons, heavy metals, and other substances. Many of the businesses in the section discharged their hazardous wastes directly onto the ground surface or through injection wells. From the description that URS gave Ms. Von Sydow regarding the on-site septic tank and leach field, she believes that the original owner of the BC site created an injection well by having a brick-walled leach field with a gravel bottom. Out of 200 sites having leach lines that she has investigated, approximately 10 have discharged contaminants to the groundwater. Page 1 of 2 CAD98137997 Conta Report (continued) BC Laboratories Kern County Environmental Health Dept. (KCEHD) Discussion, continued: · . 5/22/95: The groundwater level at BC is currently approximately 10 to 20 feet bgs because of additional water in the canal derived from Sierra Nevada melt water. Thc California Highway Patrol has a Class 5 (injection well) on their property located next door to BC.

The old fan deposits are underlain by the Kern River-Chanac deposits..'., Permeability decreases in the older deposits, whereas the recent deposits have a higher permeability. The Co~,oran clay is located much farther to the west of Bakersfield, approximately 10 miles away. A ,'300-f00t. clay deposit has been described by Bob Dale in a U.S. GeolOgical Survey open-file report on Kern_ River. alluvium. There are also some deeper clay horizons underlying the "300-foot clay." An unconfined alluvial aquifer underlies the BC Labbratories (BC) site. There may be local confmement~'~fr°m the "300-foot clay" horizon, but there is no regional confinement. Based on electric logs, the regional slope is 200 feet per mile from north to south. Good water is found down to 2,700 feet below ground surface (bgs). The nearby Calloway Canal is unlined, and is good for groundwater recharge. The groundwater flow is to the west or northwest if the main source of recharge is from the Kern River. Water from some of the wells near the BC site area had a poor flavor due to petroleum content, presumably from nearby refineries.

Contact Date: 1/23/95 1/31/95 2/28/95 Contact Facsimile Number: Contacted by URS Representative: Carol Weinstein 'i',. Discussion: 1/2~95: Mr. Haslebacher stated that the underlying lithologic sediments at BC Laboratories (BC) are coarse. sand to gravel. The site is located on the high-energy deposifional environment of an alluvial fan, a jumbled .and chaotic environmenc There is some degree of perched water in this environment. Kern County Water Agency (KCWA) has a temperature equalization pond located on the north side of the Golden State Freeway, This pond supplies approximately 40 percent of groundwater used in the area. The second function of the pond is to act as recharge to groundwater. Between 1993 and 1995, the elevation of groundwater has fluctuated from 50 to 150 ' feet below the ground surface (bgs). There is considerable fluctuation in groundwater.levels, both temporally and spatially. The pond and the Calloway Canal act as short-term influences on groundwater elevation. : · There are some contamination problems in the arum A nearby business, Davis Oil Company, has an ongoing problem with petroleum contamination. Petroleum refineries have been in the area since the 1920s. Since the KCWA is near the BC site, URS will visit Mr. Haslebacher following the site visit on 1131195. 1/31/95: Mr. Haslebacber stated that there is a 6-month lag in determining what the groundwater elevations are in terms of recharge and discharge in the general area of the BC site. That means the rainfall in that area this current season will not manifest itself until sometime in the future. The Kern River is probably the major factor in determining the direction of groundwater flow from the site, which is to the southwest. The California Water Service wells are not deep wells, and there are no major production wells in the site area. Well fields for the KCWA temperature equalization pond are located approximately 10 miles to the southwest. Page 1 of 2 CAD981379977 Contact-Report (continued) BC Laboratories Kern County Water Agency (KCWA) Discussion, continued: W28/95: Mr. Haslebacher stated that, since the recharging Calloway Canal is adjacent to the site, groundwater flow direction is away from the canal, and therefore, away from the site. Mr. Haslebacher thought that the capture zones for the municipal wells, located approximately 0.45 and 0.60 mile south from the BC site, were probably too far from the BC site to capture any contamination by pumping groundwater. Mr. Haslebacher believes that thc B(~ site is riding on top of the groundwater mound, and thc mound shifts and changes on a daily basis. The depositional environment underlying the site is heterogeneous and anisotropic, and includes high- and low-energy regimes. There is probably every grain size underlying the site. During the past 3 years, the groundwater elevation has fluctuated from 50 to 150 feet bgs. Mr. Haslebacher believes that any contaminant migration would be imposaible to determine, but would likely have a vertical component, as opposed to a horizontal one. The up- and dOwngradient flow would tend to flush out metals. In addition, the nearest wells are screened very deep. If there were metals underlying the site, there would be few in the non-saturated zone ~' "-., . :'j, ,i. .Z..~ ~' .. ~ ~:, .~ ':'./ '"d>~5~'/,~5 :.*¢i~' ",,~,C~~ '~Z!?~:,'::- . :i ,~:,:~ .% ...... ,,~, ...,..;,:,: .:.~ .=. ,, ' "' ~, :, ,c; ";.',:. .

II I I Disg/ussion: URS Consultants, Inc. (URS) contacted Mr. Swain for information regarding background levels of metalsin soil and groundwater in the Bakersfield area. Mr. Swain stated that, south of Bakersfield, there are high levels Of total dissolved solids CIDS) with high selenium from outcrops of Miocene shales that are the source c~f the selenium. Uranium levels are also high in the area, and the uranium is ubiquitous.. Because the BC site is high up on the alluvial fan depositional environment, there are few naturally occurring metals with high concentrations. A recent study by U.S. Geological Survey (USGS) revealed that most of the samples out of the 297 samples taken had an arsenic concentration of less than 10 milligrams per kilogram (rog/kg). The analytical' result of 4.1 rog/kg total concentration arsenic detected in subsurface soils at the BC site is not out of line with background levels. The 4.1 rog/kg level is normal for the. Bakersfield area, and consistent with the background level.

(URS) representatives arrived on site at 1330 hours on January 31, 1995, and were met in the parking lot by Joe Eglin, owner of BC Laboratories (BC), and his son, Rich Eglin. We began a tour of the former BC site by entering the front door of the facility, now an employment procurement agency, Continental Labor Resources, Inc. (Continental). Continental currently employs 3 or 4 people. Mr. Eglin showed URS two bathrooms and office space in the front part of the building. The bathrooms discharge to a septic tank located in the front grassy portion of the property. We proceeded to the rear portion of the facility, which housed the laboratory operations. The rear portion of the building consisted of a large room with 2 smaller rooms behind the large room. With the exception of chemical reagent shelving, 6 floor drains (one drain is a floor sink), and a limimd supply of laboratory glassware, there were few signs that the large room had been utilized as a laboratory. Two of the floor drains were below safety showers. The floors in the laboratory room were intact, revealing areas where piping had been installed from floor drain to floor drain, and were then covered in concrete. Photographs taken during the Preliminary Investigation (PA) showed that the floor was covered with tiles, some of which were stained. The floor tiles have since been removed. There were no noticeable stains on the concrete. The western wall of the laboratory room is currently utilized for the storage of former BC client records. The inorganic analysis BC lab has relocated to 4100 Atlas Court. We were joined by Don Rigdon after the facility tour began. Mr. Rigdon had previously worked for David Anderson, the builder and former owner of the property. Mr. Rigdon witnessed the installation of the rear septic tank. This tank was installed to contain the rime. am generated from a soap manufacturing operation. Mr. Rigdon explained that one of the rear smaller rooms, approximately 240 square feet, was used as the chilling room for soap manufacture. Mr. Rigdon assisted Mr. Anderson in the mixing and pouring of the soap. The soap manufacturing operation was apparently unsuccessful, and Mr. Anderson sold the property to Mr. Eglin. The chilling room was later utilized by BC as a room for an Inductively Coupled Argon Plasma (ICAP) spectrometer, a metal analyses instrument. This room is currently used as a storage room, Page I of 2 EPA PA/SI $R00004 c^Do81a79977 Site Reconnaissance BC Laboratories Interview and Observation Report Comments and ObserVations (continued) I/31/95 and contained several miscellaneous items, such as a ping-pong table. The second smaller room in the rear portion of the building was used for nitrogen analysis. The southwest comer of this room had circular mst stains on the floor. The mst stains approximated the size of a 55-gallon chum. Mr. Eglin stated that no drums were stored in this area during the BC operation. A garage door from this room led to the rear of the property, which was formerly enclosed by 6-foot-high chicken-wire fencing, but is currently in poor condition, with portions of fencing down. The rear of the property consists of a blacktopped area that contained a 2-foot-cliameter circular lid of the septic tank, a smaller diameter circular lid of the seepage pit, and a 3- to 4-inch depression in the soil that resulted from the hole left from the hand-augered sample collected by Mr. Eglin's consultant. The blacktopped area is approximately 1,200 square feet, and was always blacktopped during the BC operation. A concrete area, approximately 180 square feet, is located in the northeast comer of the fenced area, and has a berm approximately 2 inches high on three sides. The unbermed side is the one closest to the building, and is the topographic low of the site property. During BC's operation, up to 12 drams containing hazardous waste were stored in this area prior to being transported off-site. The wastes consisted of acids and caustics that were used in the laboratory analyses. After the chemical analyses, these substances, including whatever metals were detected, were neutralized before they were placed in the drums. Only washdowns of the laboratory equipment went into the rear septic tank. Mr. Rigdon provided some details regarding the installation of the rear septic tank. The.septic tank consisted of two partitions, was approximately 6 feet deep, and was installed approximately 2 feet from the ground surface. A pipe led from the septic tank to the seepage pit. The seepage pit is approximately 20 feet deep, with a gravel surface and concrete-lined walls. The diameter of the bottom of the seepage pit is approximately 5 feet. The geologic material in the seepage pit area was sandy to the extent that the hole kept collapsing on itself as it was being excavated. Mr. Rigdon had no knowledge of the specific details of the front septic tank. In addition to metal analyses, BC also analyzed plant tissue for nitrogen, potassium, and phosphorus content, as well as soil analysis and potable water analysis. There was apparently no formal closure from a regulatory agency when BC ceased operations. There were no organic analyses performed at BC, nor were polychlorinated biphenyls (PCBs) stored or used on-site. BC employed approximately 40 people when the facility was operational. The BC site is locatexl adjacent to the Calloway Canal, an east to west flowing surface water body, operated by Kern County Water Agency. Site runoff from the rear of the facility in the drum storage area, and other areas as well, flows into the canal. The southeast portion of the site property is the topographic low of the site. Mr. Eglin also showed URS the former underground storage tank (UST), which is located in the southeastern portion of the current parking lot. The area was demarcated by a triangular-shaped raised blacktop surface in the parking lot.

(URS) as part of the Alternative Remedial Contract Strategy (ARCS) Program. ARCS is executed under Contract No. 68-W9-0054 for the U.S. Environmental Protection Agency (EPA) in Regions IX and X. ARCS serves as the primary guide for the integration of sa~l.jng functions into project activities for Work Assignment (WA) No. 54-27-9JZZ, Which was activated on June 14, 1993. This Field Sample Plan presents the objectives, rationale, and procedures for groundwater sampling at and in the vicinity of the BC Laboratories (BC) site. The Field Sample Plan described herein was prepared in accordance with the EPA regional guidance document entitled preparation of a U.S. EPA Region 9 Field Sample Plan for EPA Lead Superfund Pro.iects (EPA 1993). This document and the Quality Assurance Project Plan for Site Inspections (QAPjP) (URS 1992) form a set of project plans for this WA. 1.! Investigation Strategy Groundwater samples [estimated depth 20 to 35 feet below ground surface Cogs)] will be collected from the BC facility using the HydroPunch® sample collection method system. Should excessive cobbles or gravels be encountered in the subsurface, preventing the direct punch method of sample collection, the HydroPunch® hole will be abandoned and filled with neat cement grout. A second attempt to collect a sample from the same general area will be made. Should the second attempt to collect a sample at a given sample location point fail, the HydroPunch® hole will be abandoned, filled with neat cement grout, and no further attempt to collect a sample from that location will be made. In the unlikely event that the CPT meets refusal at three consecutive sampling sites (each with two attempts), this phase of the investigation will be terminated, as ' directed by the Site Assessment Manager (SAM). At the discretion of the SAM, a subsequent investigation using an 8-inch hollow-stem auger rig may be conducted. The auger rig would be used to drill to the water table, at which point the HydroPunch® would be advanced beyond the lead auger to collect the sample. The sample collection and handling methodologies will be unchanged. No subsurface soil samples will be collected. All samples will be analyzed for Contract Laboratory Program Analytical Services (CLPAS) total metals (filtered and unfiltered), and CLPAS volatile organics O/OAs). Analyses will be conducted by the EPA Region IX laboratory, according to the CLPAS SOW. All upgradient (background) groundwater samples will also be analyzed using these organic and inorganic analytical methods. BC Laboratories !~' Section No.: 2.0 Field Sample Plan Revision No.: !

Data collected will be used to generate an HRS score for the groundwater pathway for the site. The surface water, soil exposure, and air pathways are not pathways of concern. There is no existing groundwater data from on-site wells to adequately characterize groundwater. · Assess the extent of metal and/or volatile organics contamination (if any) from the seepage pit in groundwater in the area between the defunct BC facility and the downgradient property of the California Highway Patrol. .,~.. .·.

The EPA site name is BC Laboratories (BC), as listed in CERCLIS. The 13(2 Facility is located at 4100 Pierce Road in Bakersfield, Kern County, California. The property was first developed as a soap manufacturing plant. The previous owner developed the property and constructed the existing building for a soap manufacturing operation in the mid-1970s. Two septic tanks were installed at the time of the site development. The front septic tank was installed to receive regular bathroom wastes. The rear septic tank was installed for the purpose of receiving wastewater, caustic soda, and vegetable oil associated with the soap manufacturing operation. The septic tank was connected to a seepage pit via underground piping. Details of the installation of the tanks and pit are not available. The site building was occupied by the soap manufacturer for approximately 2 years. The 13(: facility began operations in 1977, at which time'it was owned and operated by Joseph Eglin. Mr. Eglin is also the current owner. BC operated as an analytical laboratory, specializing in inorganic analyses (metals), plant tissue analysis, potable water analysis, nitrogen, phosphorous, and potassium analysis, and soil analysis. 13(: discharged wastewater from washing and rinsing laboratory equipment to the rear septic tank and seepage pit. BC operated a second laboratory in Bakersfield for organic analyses. During operations, BC generated an unknown quantity of wastewater from washing laboratory glassware, which was discharged to the rear septic tank connected by underground piping to a seepage pit. Both the septic tank and the seepage pit are located in the rear (eastern) portion of the site. The seepage pit was excavated to dimensions of approximately 20 feet in depth;, with a diameter of approximately 4 to 5 feet. During excavation of the seepage pit, the geologic material was determined to be coarse-grained and unconsolidated to the extent that the excavation kept collapsing. BC Laboratories waste products generated during the inorganic analyses included diluted acids and caustics. The waste materials were stored in the rear yard of the facility in 55-gallon drums. The drums were placed upon a concrete pad, which was bermed to a height of approximately 2 inches on three sides. The stored wastes were periodically removed from the premises by a licensed transporter to a permitted TSDF under a hazardous waste manifest. BC estimates that the amount of waste hauled from the site annually was approximately 12,000 pounds, and included soil from sample analysis and liquids. According to BC representatives, polychlorinated biphenyls (PCBs) were not stored on-site. Small quantities of solvents, such as carbon tetrachloride and methyl isobutyl ketone, were used on-site for cleaning glassware. BC Laboratories Section No.: 3.0 Field Sample Plan Revision No.: ! UPS Consul~, Inc. 07/14195 ARCS EPA Region IX Page $ Contract No. 68-W9-0054/WA 54--27-gJ7.Z BC ceased operations at the Pierce Road facility and combined the inorganic laboratory with the organics laboratory at 4100 Atlas Court in Bakersfield in October 1990. All chemicals, chemical containers, and other materials associated with the BC operations at Pierce Road were removed to Atlas Court in October 1990. Only shelving for chemical reagents and boxes of BC client records remain at the site building, as observed during the site visit. The BC facility currently rents out the office space of the old laboratory building to an employment procurement office. 3.2 History of Site Investigations 3.2.1 U.S. Environmental Protection A~encv The.13C Laboratories site was listed on the CERCLIS database on August 5, 1991.

The valley is an asymmetrical synclinal trough with a more gently dipping eastern limb. It is underlain by a thick (up to 60,000 feet) sequence of sedimentary units. The elevation of the valley floor ranges from below sea level to approximately 400 feet. Sutter Buttes (with the highest province elevation of 2,100 feet) and the Kettleman, Elk, and Buena Vista hills provide the only significant' topographic relief in the province. Two major rivers, the Sacramento and the San Joaquin, and their tributaries, drain the northern and southern portions of the province, respectively. The only drainage from the pro. vince is through the San Francisco Bay and into the Pacific Ocean. The BC site is located in the Kern River alluvial fan, (the Kern River is a tributary to the San Joaquin River). The unconsolidated continental deposits that comprise the alluvial fan consist mainly of alluvium and lacustrine (lake) deposits. According to an investigation conducted at BC by GCS in 1992, the deposits underlying the site consist primarily of coarse sand. The site is adjacent to the Calloway Canal, a diversionary canal from the Kern River, which is located approximately 1 mile to the southeast. The Kern River is the principal source of recharge to the area; the BC site also receives recharge from the adjacent CaUoway Canal. Groundwater is unconfined at the site and occurs at approximately 25 feet bgs. 3.3.3 Groundwater Usaee The City of Bakersfield operates approximately 130 municipal water supply wells within 4 miles of the BC site. In addition, there are approximately 8 domestic wells serving populations ranging from 25 to 3,000. Groundwater issues of concern are: · groundwater provides drinking water to the City of Bakersfield within 4 miles of the site; · the BC site overlies an unconfined aquifer (i.e., the water table forms the upper boundary of the aquifer), which provides groundwater for municipal, domestic, and irrigation uses; and · the groundwater flow is believed to be in a southwesterly direction towards two of the City of Bakersfield's municipal supply weUs.

Because of the. high-energy depositional' environment of the upper portion of an alluvial fan, the aquifer consists of coarse to fine sand and gravels, with minor amounts of clay change in composition both ....hoHzonta and vertica . · BC has nOt operated an on-site well. Groundwater flow direction in the BC vicinity. is to*' the southwest. ' '" "' :. Groundwater in the site area occurs as an unconfined aquifer, and the groundwater. flow direction is towards tWoOf Bakersfield's municipal wells;' thus, the quality of groundwater migrating from the site must be evaluated. The potential for past site' · activities to affect groundwater quality will be assessed. 5.1.2 HydroPunch® Samples Eight HydroPunch® (HP) samplesWill be installed andsar~ppled.

The depth to groundwater is anticipated to be between 20 and 35 feet bgs. The HP-II is an air-tight, water-tight sealed intake screen and sample chamber that is isolated from the surrounding environment as the tool advances. The HP-II is approximately $ feet long, with a 2-inch outside diameter (O.D.), and a wall thickness of one-quarter inch. A disposable cone is attached to the body of the HP-II, and is driven into the water-bearing formation. Soil. friction holds the disposable point in place, while the body of the HP-II is retracted, thus allowing water to enter through a screen into the HP-II. ~i Borings will be advanced utilizing the direct-punch method. When the desired depth is reached, the HP-II is attached to a hollow drive pipe of large enough inside diameter (I.D.) to permit passage of a thin bailer (3/4-inch I.D.), and lowered insid~ the hollow-stem augers. The sample chamber is then pulled back, and formation water allowed to enter the screened interval. Since these samples are groundwater grab samples, there will be no purging to constant pH, conductivity, turbidity and temperature prior to sampling; however, these parameters will be logged for each sample by reserving an aliquot of the bailed sample for field parameter measurement. Given the method of groundwater sample collection, no soil borings will be collected. ~ The amount of time that the HP-II remains in place is dependent on the lithology Of the aquifer. Groundwater samples at each location will be collected using either a 3/4-inch I.D. bailer (of 45 mi capacity), or by using a peristaltic pump fitted wiih Teflon-lined Tygon tubing. If groundwater is found at 25 feet bgs or at shallow.er depths, then it is anticipated that the peristaltic pump will be capable of drawing a sample to the surface. Depending on recharge rate, the samples would then be collected significantly more quickly than with the 45 mi bailer. The tubing will' l~e dedicated to each sample location, and thus will not be decontaminated. One set of metals groundwater samples will be filtered with a 5-micron (gm) membrane filter, and transferred to appropriate containers for CLPAS Total Metals analyses. The second set of metals samples will not be filtered and will be transferred to 1L polyethylene bottles for CLPAS Total Metals analyses. Laboratory QA/QC analyses will be conducted on the specified environmental sample, for which double sample volume will be collected. The samples for volatile organic analysis will be not be filtered; the sample aliquot for this analysis will be transferred directly into three 40 mi VOA vials, preserved with 1:1 hydrochloric acid (HCI) to give a pH of less than 2, which will subsequently be inverted to check that no bubbles are present. l~c La~r~tori~s (' ('- Section No.: S.0 Field Sample Plan Revision No.: 1 URs Consultants, Inc. 07/14/~ ARCS EPA Region IX Page 16 Contract No. 68-W9-OOS4/WA 54-27-9JZZ Table 6=4 Summary of Environmental and Control Samples BC Laboratories Analysis Env.

All down-hole equipment will then be steam-cleaned. Bailers used to collect the HydroPunch® samples will be decontaminated by the sampling team. The driUing subcontractor will provide a 55-gallon drum (or EPA- approved equivalent) to contain and transfer aU decontamination water. All equipment decontamination activities will be entered in the Equipment Decontamination Log (Appendix A, Exhibit 3.7-1).

All groundwater samples earmarked for VOC analysis 'will be coUected in preserved 40 mi VOA vials. Prior t° the 'Collection :a VOA vial sample~ a test vial will be collected and acidified with two drops of 1:1 HCI to determine '~vhether this 'quantity of acid is sufficient to reduce the pH of the sample to less than 2. If two drops are not sufficient, then further drops Of 1:1 IICI must be added with a' disposable pasteur pipet until a pH of less than 2 is achieved. A second vial must then be prepared with the number of drops of 1:1 HCI determined in the first test, to confirm that the required pH has been achieved. Since all the groundwater samples are to be collected from the same aquifer, this test need only be conducted once. BC Laboratorie~ Field Sample Plan Section No:. 7.0 UR.5 Comultant~ Inc.

These samples will be of the greatest value in characterizing metals contamination at the site, since the unfiltered samples are expected to be very turbid, due to the HydroPunch® sample collection method. · If recharge is too slow to collect the filtered metals sample, then only the three 40- mi VOA vials for volatile organics analysis will be collected. VOG samples will be collected in 40 mi VOA vials, preserved with HCI. The vial will be inverted after filling, and tapped to ensure that no bubbles are present...If ..bu~bble~. a~re observed, the VOA vial will be re-filled, and the process repeated until a VOA without bubbles is obtained..The VOA vial will then be stored on ice until shipment. .. .

If the peristaltic pump is used to collect samples, then an equipment rinsate sample will be collected by pumping DI water through the Teflon- lined Tygon tubing prior to the collection of an environmental sample (since the tubing is dedicated to each sample location and thus is not decontaminated). Since the DI water does not come into contact with the peristaltic pump, no decontamination of the pump is required..In the event that both the peristaltic pump and the bailer are used, an ~.. equipment blank sample will be collected from each device. Vola. ttle Organics Samples Organic-free water will be poured through the decoritaminated 45 mi bailer and collected in three 40 mi VOA vials.

The equipment blank sample numbers will be recorded using the Field QA/QC Summary Log (Appendix A, Exhibit 2.4~..6).' .. :: 7.7.4 Laboratory'_ _OC Samples ' ""' One sample per twenty environmental samples will be designated as a laboratory QC sample, to be used for matrix spike/matrix spike duplicate (MS/MSD) analysis. Therefore, one MS/MSD each will be required for filtered metals analysis, unfiltered metals analysis, and volatile organics analysis. Since the intention is to determine whether a significant matrix effect is present, the HP-6 has been selected as the laboratory QC sample location, since it is downgradient from the potential source area. The environmental sample collected from this location will consist of a double sample volume for each analysis. In the event that refusal is encountered at this location, an alternative downgradient location will be selected. These are, in order of preference: HP- 7; HP-8; and HP-5.
