City of Redlands, Development Services Project No. 62934.22 May 8, 2013 1.0 INTRODUCTION AND BACKGROUND This document presents the results of the SCS conducted for the APN 0171-022-13, (Site), an approximate 1 .37-acre property located on the north side of Redlands Boulevard, approximately 400 feet west of Texas Street in the City of Redlands, California. The approximate location of the Site, within its regional setting, is presented on Figure 1 . The Site is vacant except for five large, corrugated sheet metal (steel/tin) ASTs, a transfer tank, and associated piping, located in the northeast portion of the parcel, as shown on Figure 2. LOR was retained by the City of Redlands to perform the SCS. The work was performed in accordance with the USEPA-approved SAP, dated November 7, 2012 (LOR' 2012). The primary objective of the SCS was to determine whether potential contaminants were present in the subsurface soils beneath the Site at concentrations that could present a potential hazard to human health or the environment. During the SCS, subsurface soil within the parcel boundary and samples of the contents of the ASTs and transfer tank were collected and analyzed to achieve the stated objective. 2.0 SITE DESCRIPTION AND HISTORY The Site is 1.37 acres of vacant property, except for the northeast portion which contains the five ASTs, transfer tank, and associated piping. The ASTs are approximately 25 feet in diameter and 20 feet high. The transfer tank is partially buried with approximately 4 feet underground and 2 feet aboveground. The transfer tank is approximately 6 feet in diameter, and is the same corrugated sheet metal construction as the ASTs. Steel pip/ng, that ran both overhead and underground, is present in the area of the ASTs. An old concrete retaining wall is present along the south side of the ASTs. The remainder of the Site is vacant, with numerous trees and bushes present. The Site is relatively planar with an overall slope to the south. A small drainage grate to a storm drain in West Redlands Boulevard is present near the south- center portion of the property. The area of the Site is commercial, with railroad tracks and vacant land to the north, vacant land to the east and west, commercial properties to the southeast and a park south of West Redlands Boulevard (Figure 2). The City of Redlands has no specific developments plans for the Site; however, the Site is currently designated open space/park with no anticipated future land use change. l � �� '�� GEOTECHNICAL GROUP,INC. City of Redlands, Development Services Project No. 82934.22 May 8, 2013 2.1 Site History The Site is owned by the City of Redlands, which has been the owner since the early 1950s. Ownership prior to the City of Redlands, and prior uses with respect to the product the ASTs contained, could not be readily determined. However, based on the development of the adjacent parcels, to the east by 1915, it is possible that the onsite ASTs, transfer tank, and associated piping were constructed in that time period, and may have been associated with the adjoining oil company business. The Site, based on aerial photographs, Sanborn Fire Insurance Maps, and onsite observations, has been vacant land, except for the five large ASTs, associated piping, and underground transfer tank, all located in the northeast portion of the parcel. The 1930 aerial photograph shows the west portion of the parcel as part of the Zanja Creek, and lower in elevation than the area of the ASTs. Redlands Boulevard does not go past the Site because of the Zanja Creek. In the 1938 aerial photograph, Redlands Boulevard is present, and the west portion of the Site is filled in. In both the 1930 and 1938 aerial photographs, the ASTs are present. It is unknown what product(s) were stored in these ASTs, but diesel, kerosene, heating oil, and/or smudge pot oil are likely to have been stored in the ASTs. Soil staining is evident at the base of some of the ASTs, whether through vandalism or natural breakdown of the ASTs. 3.0 ENVIRONMENTAL SETTING The Site is located in a commercial area at the west end of the downtown area of Red|ondm' Vacant land is located to the east, with commercial businesses located to the southeast. To the north are railroad tracks and vacant land, followed by Stewart Avenue, and then a school. South of the Site is Redlands Boulevard followed by a park, and Mission Zanja Creek. There are no other sensitive environmental receptors in the area of the Site. Redlands has a Mediterranean climate with hot, dry summers and mild, relatively wet winters. The prevailing wind generally blows from the west-northwest. Temperatures in the summer can exceed 95°F, but with low humidity. In the winter, high temperatures may not rise above 55°F during rainy days. On average, January is the coldest month with an average high/low of 68nF/43»F' while August is the hottest with an average high/low of 95vF/84oF. Redlands receives 10.22 inches of precipitation annually with most of it occurring in the winter and early spring, especially January through March, with January being the wettest month. 2 L OR GEOTECHNICAL GROUP,INC. City of Redlands, Development Services Project No. 62934.22 May 8, 2013 3.1 Topography The Site sits at an elevation of approximately 1,300 feet amsl. The topography of most of the Site is relatively planar with a gentle fall to the west-southwest. In general, storm water is by sheet flow to Redlands Boulevard, however, there is a small drainage channel located west of the area of the ASTs, which flows to a small drainage inlet/storm drain grate along the south side of Redlands Boulevard. This drainage grate (storm drain inlet) is present near the south center portion of the Site and carries storm water runoff from Redlands Boulevard, and to a much lesser degree the Site, to the unlined channel (Za jaCrneh) nouthofRed|andmBou|evard. 3.2 Geology The area of the Site is an alluviated valley floor lying between the San Bernardino Mountains to the northeast and the hills of the Redlands area and the Badlands area to the south and southeast. The dominate drainage for the region is the Santa Ana River which lies approximately 3.2 kilometers (2 miles) to the northwest. Erosion of the surrounding highlands and subsequentdeposition in the lower regions by the Santa Ana River and its tributaries has resulted in the deposition of alluvial units over the valley floor. The thickness of these alluvial units is in the vicinity of the Site is approximately 550 to 600 feet. 3.3 Hydrogeology The Site is located in the Bunker Hill Subbasin, which is situated within the Upper Santa Ana Valley Groundwater Basin. The Bunker Hill Subbasin consists of the alluvial materials that underlie the San Bernardino Valley. This subbasin is bounded by contact with consolidated rocks of the San Gabriel Mountains, San Bernardino Mountains, and Crafton Hills, and by several faults. The southern boundary is the Banning fault, the east boundary is the Redlands fault, the San Andreas fault is roughly the northern boundary, the Glen Helen fault abuts the northwest boundary, and the southwest boundary is the San Jacinto fault. The Santa Ana River, Mill Creek, and Lytle Creek are the main tributary streams in the subbasin (California Department of Water Resources, 2004). The Bunker Hill Subbasin contains several groundwater contamination plumes, which locally includes the Redlands plume, located between Judson Street and Waterman Avenue. This contamination plume is primarily composed of TCE and perchlorate, with lower levels of PCE and DBCP. 3 � �� ]�� GEOIECHP4ICAL GROUP,INC. City of Redlands, Development Services Project No. 62934.22 May 8, 2013 Recent groundwater well data from the Cooperative Well Measuring Program, Fall 2008 (Western Municipal Water District and San Bernardino Valley Municipal Water District, 2009) and the California Department of Water Resources (DWR) website indicate that the current depth-to-groundwater beneath the Site is over 180 feet below the ground surface (bgs), and has been slowly dropping over recent years. The nearest well in the Cooperative Well Measuring Program is State Well No. O1S03VV20H001S (Well #41), located approximately 500 feet south-southeast of the Site, situated just west-northwest of the intersection of Texas and State Streets. This well has groundwater measurements reported from April of 1993 to November of 2008. The groundwater levels recorded over this time period ranged from approximately 118 to 235 feet bgs. Some of these measurements wre recorded during active pumping of the well. Groundwater monitoring wells placed approximately 600 feet east of the Site, encountered water at approximately 186 feet bgs. The regional groundwater flow direction is towards the Santa Ana River, generally in a westerly direction, coincident with the fall in local ground surface topography. 4.0 GEOPHYSICAL SURVEY Prior to sampling activities, a geophysical survey was conducted to identify potential (unknown) subsurface features that may be present beneath the Site. The geophysical survey was conducted by Mr. Donn Schwartzkopf with Terra Geosciences, under the direction of this firm. Mr. Schwartzkopf has over 28 years of professional experience, and is a California Licensed Professional Geologist (PG 4094), Certified Engineering Geologist (CEG 1459), and Professional Geophysicist (PGP 1002). Color photographs taken during the geophysical survey activities are presented within Appendix A. 4.1 Electromagnetic Survey To investigate potential subsurface objects or features of metallic composition, we performed an electromagnetic search around the ASTs, utilizing a deep-search, Fisher W1-Scope Gemini-3 metal detector. This instrument will detect any large-sized metallic and/or conductive anomalous objects. Using this EM detector method oma primary search tool is the preferred reconnaissance method to evaluate whether buried metallic and/or conductive objects are present. This EM survey method transmits a radio frequency signal (81.93 kHz) into the ground, wherein if a conductive object is encountered, an electromagnetic field will be generated around that object, which the receiver unit will detect. The depth of signal penetration and detection varies, 4 � �� GEOTECHNICAL GROUP,INC. { City of Redlands, Development Services Project No. 62934.22 May 8, 2013 depending on several factors such as ground mineralization and moisture, length of burial time, and the size, shape, and depth of the object. Typically, this instrument can detect a 55-gallon drum to a depth of 1O± feet bgs and automobile-sized objects to 25± feet bgs. Larger UST-sized objects should be very detectable and therefore, the ' | possibility that a buried UST or other such large-sized metallic and/or conductive target not being detected is considered to be low. The EM scanning located all the underground piping associated with the ASTs. No piping went outside of the area of the ASTs. No other significant subsurface metallic object(s) or feature(s), such as USTs or drums, were detected. The EM scanning was followed up by the use of GPR. A GSSI S|A° SYSTEM-2 GPR unit was used to help verify the presence of known subsurface cavities and unknown objects/features. For this project, a 400-MHz antenna was used, due to its higher resolution record in the upper 10± feet of the subsurface. Data are collected by inducing a pulse of electromagnetic energy at very high frequencies into the ground using a continuous survey mode. As the electromagnetic waves are transmitted into the scanned surface, a portion of the induced pulse is then reflected back to the antenna from various boundaries at depth. These signals or reflection data are then received at the transducer and sent to the system control unit, where the returns are displayed in real-time on the digital control unit screen, and stored in the in-board computer hard drive of the SIR-2. GPR can provide high-quality data of near-surface conditions; however, it has some limitations. GPR is most effective in areas with resistive near-surface soil types such as dry gravel and sands. Clayey, silty, nooint, or conductive soils often severely limit the depth of penetration by absorbing the energy and not transmitting it. Based on the subsurface soils present at the Site, it appears that silty soils underlie the upper foot to two feet, thus possibly reducing the effectiveness of the GPR survey. The GPR scans verified the presence of underground piping, and no other significant buried objects were detected. Based on the results of the geophysical survey, no cavities or other subsurface features were identified. Underground piping associated with the ASTs are located within the area of the ASTs, with no piping located outside the area of the ASTs. 5 � �� GEOTECHNICAL GROUP,INC City of Redlands, Development Services Project No. 62934.22 May 8, 2013 5.0 FIELD SAMPLING Field narnp|ingactiyitias were conducted in general conformance with the SAP (LOR, 2012). The field sampling program was designed to address areas of potential environmental concern identified in the SAP. Bulk samples were collected from the ASTs and transfer tank. Soil samples were collected in two distinct areas. The first area of soil sample collection was from the area of the ASTs and other selected locations believed to be representative of historical operations at the Site with potential for environmental contamination. The second area of soil sample collection was the remaining area of the Site to verify the absence of any potential contamination. Grab samples consisted of the direct collection of the AST and transfer tank contents into appropriate containers. A Gooprober" push rig was used for Soil sampling. A PID was used for field screening of VOCs, where applicable, during soil sampling activities. Sampling activities took place between December 12 and 18' 2012. The boring locations are presented on Figure 3. Select color photographs taken during field sampling activities are presented within Appendix A. 5.1 Bulk Sampling Bulk sampling was conducted to obtain samples of the contents of the five ASTs, piping, and transfer tank. The five ASTs were numbered in the field by others, marked in red paint as 1 through 5. To sample the ASTs, either an existing opening was used or an opening was made in the AST to obtain the sample. Bulk samples from the ASTs were collected directly into clean glass jars. In two of the ASTs (Tanks 2 and 4), there was a lot of water present, and the samples collected had a lot of water along with some tank sludge. In Tank 2, the sludge on the bottom of the tank was incidentally stirred up prior to sampling. In Tank 4, the sample was collected without stirring the bottom of the tank. Sludge samples with no significant water were obtained from Tanks 1, 3, and 5. The transfer tank is approximately 6 feet in height, ond.hed about 4 feet of water in it. Debris is also present inihm transfer tank. A sample of the water in the transfer tank was obtained in appropriate glass and plastic bottles, by direct submergence of the containers. All of the aboveground piping was dry, no significant residual material was present, and therefore, no sampling of the aboveground piping was conducted. 6 � ��» �� GEOTECHNICAL GROUP,INC. City of Redlands, Development Services Project No. 62934.22 May 8, 2013 5.2 Push Rig Sampling A GeopnmbaTM push rig was used to collect soil samples from all the other locations specified in the SAP. The Gaoppnbmnw push rig, using a K800rV-Core4 soil sampling system, recovered 2.25-inch diameter soil cores in 5-foot lengths to a minimum of the desired sampling depths. Plastic sample sleeves were undisturbed to the extent possible during sample preparation. Native soils and fill materials with evidence of contamination, including visual and olfactory, were encountered in only the upper soils around the ASTs. The soils present were predominantly silty sands and sands with gravel. Fill materials were present in most of the borings at varying depths. The PID readings of the samples from the push rig soil borings ranged from 0 to 7.3 ppmv. Groundwater was not encountered during boring advancement. A soil classification chart and logs for the soil borings advanced with the push rig, which include descriptions of the lithology and select analytical results, are presented within Appendix B. The soil boring locations are presented on the Boring Location Map, Figure 3. 5.3 SAP Deviations • Deviations from the SAP consisted of no sample from the aboveground piping was obtainable, and sampling areas outside the area of the ASTs was increased from a 50- foot grid to a larger area, to compensate for the deeper boring depths attained in the area of the ASTs. 7 � ��^ �� GEOTECHNICAL GROUP,INC. City of Redlands, Development Services Project No. 62934.22 May 8, 2013 5.4 Sampling Summary Table A summary of all the samples collected during this SCS, including sample ID, sample date, sample depth, sample matrix, sample type, and analysis requested, is provided in a Sample Table, Table 5.4. 6.0 ANALYTICAL RESULTS The summary analytical results for the sludge, xvotor, and soil samples are provided in Tables 6.1, 6.2, and 6.3, with a brief overview provided in the following sections. 6.1 AST Sludge and Transfer Tank Water Samples The laboratory analytical results for the sludge and water samples obtained from the ASTs and transfer tank are presented in Table 6.1 . Select Title 22 metals (total), including barium, cadmium, chromium, copper, lead, nickel, vanadium, and zinc, were detected in the sludge samples at concentrations up to 63.3 mg/kg, 2.32 mg/kg, 1.28 mg/kg, 2.71 mg/kg, 41 .6 mg/kg, 0.701 mg/kg, 1 .10 mg/kg, and 384 mg/kg, respectively. Petroleum hydrocarbons, in the diesel range, were detected in the sludge samples at concentrations ranging from 130,000 to 938'000 mg/kg. The VOCs, naphthalene up to 6.8 mg/kg, and 1,2,4,-trimethylbenzene up to 0.85 mg/kg, were present in the AST sludge samples. PCBs, reported as Aroclor 1010 and Aroclor 1260' are present in all the sludge samples at concentrations up to 3.6 mg/kg and 2.9 mg/kg, respectively. The only sludge sample with reported concentrations of SVOCs is AST-4, with concentrations of 2-methylnaphthalene and phenanthrene at 298 mg/kg and 388 mg/kg, respectively. The water sample from the transfer tank, TT-1, had reported concentrations of select Title 22 metals (total), diesel-range hydrocarbons, and PCBs. The detected metals were reported with concentrations of barium (0.0967 pg/L), cadmium (0.0246 pg/L), copper (0.0182 //g/L)' lead (0.902 //g/L), nickel (0.0140 //0/L)' and zinc (17.2pg/L). The diesel-range hydrocarbons were reported at 46.9 pg/L). The PCBs Aroclor 1016 and 1200 were reported at concentrations of 36 pg/L and 29 pg/L, respectively. Some of the concentrations of COPC, including cadmium, zinc, 2'rnethy|nmphtho|ene' naphthalene, and PCBs Aroclor 1010 and 1260, were at levels that exceed the USEPA RSLs (USEPA, 2012) for residential soil and/or tap water. 8 � �� '��. GEOTECHNICAL GROUP,INC. City of Redlands, Development Services Project No. 62934.22 May 8, 2013 No reportable concentrations of oil-range hydrocarbons and OCPs were detected in the AST and transfer tank samples. The A & R laboratory analytical results with QC data and CoC are provided in Appendix C. 6.2 Soil Samples at ASTs The laboratory analytical results for soil samples obtained from borings placed around the ASTs are presented in Table 6.2. Select Title 22 metals (total), including barium, cadmium, chromium, cobalt, copper, lead, mercury, nickel, vanadium, and zinc, were detected in the soil samples at the ASTs at concentrations up to 67.5 mg/kg, 2'76 mg/kg, 16.4 mg/kg, 8.79 mg/kg, 17.9 mg/kg, 134 mg/kg, 0.052 mg/kg, 10.8 mg/kg, 30.7 mg/kg, and 464 mg/kg, respectively. Petroleum hydrocarbons, in the diesel and oil ranges were reported in soil samples to a maximum depth of 15 feet bgs, at concentrations uptw4,B1Omg/kg and 690 mg/kg, respectively. PCBs, reported as Arochlor 1260, was detected in four of the samples up to a maximum of 0.15 mg/kg. Concentrations of OCPs, VOCs, and SVOCs were not detected above their respective laboratory reporting limits. No COPC were reported at concentrations that are at or above the USEPA RSLs for residential soil. The A & R laboratory analytical results with QC data and CoC are provided in Appendix D. 6.3 Soil Samples at Remaining Site Area The laboratory analytical results for soil samples obtained from borings placed over the remaining area of the Site and the drainage that extends from the ASTs to the storm drain along Redlands Boulevard are presented in Table 6.3. Select Title 22 metals (total), including antimony, arsenic, barium, cadmium, chromium, cobalt, copper, lead, mercury, nickel, vanadium, and zinc, were detected in the soil samples at the ASTs at concentrations up to 5.01 mg/kg, 0.62 mg/kg, 146 mg/kg, 2.27 mg/kg, 23.0 mg/kg, 7.60 mg/kg, 120 mg/kg, 661 mg/kg, 0.372 mg/kg, 30.1 mg/kg, 20.1 mg/kg, and 469 mg/kg, respectively. Petroleum hydrocarbons in the diesel range were reported in sample B-19-3 at 70 mg/kg. The OCP chlordane was reported in sample B-21-3 at ().012 mg/kg. Concentrations of oil-range hydrocarbons, PCBs, VOCs, and S\/OCs were not detected above their respective laboratory reporting limits. The concentration of chlordane reported is below the USEPA RSL for residential soil. In one sample, B-17-3, lead was reported at 661 mg/kg, which exceeds the 9 � �� GEOTECHNICAL GROUP INC. City of Redlands, Development Services Project No. 62934.22 May 8, 2013 USEPA RSL for residential soil.

The A & R laboratory analytical results with QC data and CoC are provided in Appendix E. 7.0 ANALYTICAL FINDINGS The analytical results indicate the sludge in the ASTs and transfer tank water have primarily diesel-range hydrocarbon contamination with some PCBs present. The diesel-range petroleum hydrocarbons were reported in the sludge samples and water sample up to 936,000 mg/kg and at 46.9 nnQ/L renpmntiwa|y, with the PCBs Aroclor 1016 and/or Aroclor 1260 detected in all of the samples, some at concentrations above the USEPA RSL for residential soil or tap water. Only the sample from AST-4 had reported concentrations of SVOCs, with 2-methylnaphthalene above the USEPA RSL for residential soil. In the area around the ASTs, petroleum hydrocarbons, both diesel- and oil-range, are present. The concentrations of diesel- and oil-range hydrocarbons were reported up to 4,910 mg/kg and 630 mg/kg, respectively. Except for boring B-3, these concentrations of petroleum hydrocarbons appear to be relatively shallow, within the upper 5 feet. However, deeper assessment was not conducted beneath 3 feet bgs at borings B-6 and B-7, where diesel-range hydrocarbons were reported at concentrations ranging from 490 mg/kg to 916 mg/kg. Within boring B-3, diesel-range hydrocarbons up to 980 mg/kg were encountered down to 15 feet bgs; however, no petroleum hydrocarbons were detected at 20 feet bgs. PCBs were the only other significant COPC detected in the soil samples around the ASTs. The PCB, Aroclor 1260, was reported up to a maximum concentration of 0.15 mg/kg in four of the soil samples. The reported concentrations of PCBs were all below the USEPA RSLs for residential soil. Some elevated concentrations of Title 22 metals (total), including cadmium, lead, mercury, and zinc, were reported, but are less than the USEPA RSLs for residential soil. The remaining areas of the Site had reported COPC, including elevated Title 22 metals (total), including antimony, arsenic, barium, cadmium, copper, lead, mercury, nickel, and zinc, TPH-D, and chlordane. The elevated concentrations of Title 22 metals are all less than USEPA RSLs for residential soil, except for lead at 661 mg/kg in boring B'17 at 3 feet bgs and arsenic at 6.62 mg/kg in boring B-17 at 3 feet bgs, at 10 � �� GEOTECHNICAL GROUP,INC. City of Redlands, Development Services Project No. 62934.22 May 8, 2013 3.67 mg/kg in boring B-20 at 3 feet bgs, and at 3.67 mg/kg in boring B-21 at 3 feet bgs. A TPH-D concentration was reported at 70 mg/kg in boring B-19 at 3 feet bgs. A concentration of chlordane was reported at 0`012 mg/kg in boring B-21 at 3 feet deep. 7.1 Evaluation of DQOs As provided in the SAP, three DQ0n were developed for the SCS. The first DQO involved the collection of a sufficient number of representative samples, such that potential chemical impacts to soils above the RSLs, if any, could be identified and quantified. All of the proposed sample locations were sampled and analyzed in an attempt to meet this DQO. No sample was obtained from the aboveground piping. However, it appears that the sampling and analysis conducted at the Site was adequate for all areas sampled and associated COPC. As the ASTs are still present, the vertical extent of petroleum hydrocarbons under the ASTs may not have been adequately addressed in this SCS. The second DI3CJfrom the SAP was toselect appropriate target compounds such that specific COPC were evaluated. This DQO was achieved with the planned sample analyses, based on known historical activities. Additional sampling locations and depths were added, based upon field evaluation. Analysis of COPC were conducted on samples from these additional locations and depths. The third and final DUO from the SAP was to utilize appropriate analytical methods and reporting limits such that target chemical compounds are quantified with reporting limits lower than the corresponding USEPA RSLs. This DQO was achieved for all samples and COPC, except for arsenic. The laboratory reporting limit for arsenic is 1 .00 mg/kg, greater than residential RSL at 0.39 mg/kg. All but three of the soil samples collected were non-detect at 1 .00 mg/kg. It appears the background level for arsenic is less than 1 .00 mg/kg, and therefore the reporting limit being higher than the RSL does not appear to be significant. The three samples with reported concentrations of arsenic will be discussed later. 7.2 Evaluation of DQls The SAP outlined several DUls for quantitative and qualitative indicators, including precinion, accuracy, representativeness, completeness, comparability, and method reporting limits. Precision was to be measured by the relative percent difference in the results of the field sample duplicates, MSDs, and LCSDs. The relative percent 11 � ��o �� GEOTECHNICAL GROUP,INC. City of Redlands, Development Services Project No. 62934.22 May 8, 2013 - differences for the two field soil sample duplicates were as high as 150%. However, most of the differences were around 40% or less. The wide ranges in these differences are most likely due to the heterogeneity of the soils. The two percentage differences greater than 40% and 113% were for the lead in samples B-7-3 (10.4 mg/kg) and B-7-3 DUP (2.91 mg/kg), and 150% for the diesel in samples B-19-3 (70 mg/kg) and B-19-3 DUP (non-detect at 10 mg/kg). The relative percent differences for all of the MSDs and/or LCSDs fell within the acceptable ranges up to 50%. Accuracy was to be determined by laboratory QC such as MSs, surrogate spikes, and LCSs. All of these QC measures fell within the acceptable recovery ranges, except for the elevated recoveries for some metals LCSs, LCSDs, MSs, and MSDs. The MS and MSD for zinc, associated with sample TT-1 , fell at recoveries of 200% and 206%, respectively, well above the upper end of the acceptance range at 125%. These elevated recoveries may provide at least a partial explanation for the zinc concentration in TT-1 at 17.2 mg/L, which exceeds the USEPA RSL for zinc in tap water at 4.7 mg/L. For the equipment blank associated with the soil sampling in the AST area, the LCS, LCSD, MS, and MSD for silver had very high recoveries, ranging from 673% to 702%, well above the upper end of the acceptance range at 125%. The equipment blank sample had no reported concentrations -of Title 22 metals, including silver, and therefore, the elevated recoveries for silver is not consider to be significant. The barium, vanadium, and zinc MSs and/or MSDs associated with the soil samples in the AST area were elevated above the upper end of the acceptance range at 125%. The MS and MSD recoveries for barium were reported at 165% and 159%, respectively, well above the upper end of the acceptance range at 125%. The MS and MSD recoveries for vanadium were reported at 125% and 132%, respectively, at or just slightly above the upper end of the acceptance range at 125%. The MS and MSD recoveries for zinc were reported at 131 % and 138%, respectively, just above the upper end of the acceptance range at 125%. The reported barium concentrations appear to be within the range of background concentrations, and therefore, suggesting the elevated MS and MSD recoveries for barium have not significantly affected the results. The elevated recoveries for vanadium and zinc are within 10% of the upper end of the acceptance range, and therefore, no significant impact on the analytical results is anticipated. 12 L©R GEOTECHNICAL GROUP,INC. City of Redlands, Development Services Project No. 62934.22 May 8, 2013 For the equipment blank associated with the soil sampling in the remaining area of the Site, the LCS, LCSD, MS, and MSD for silver had very high recoveries, ranging from 673% to 702%, well above the upper end of the acceptance range at 125%, similar to that for the equipment blank for the soil sampling in the AST area, as the same [l[ data was utilized for both. The equipment blank sample associated with the soil � sampling in the remaining area of the Site had no reported concentrations of Title 22 metals, including silver, and therefore, the elevated recoveries for silver is not consider to be significant. With regard to representativeness, an aerial photograph review and a geophysical survey were used in an attempt to identify locations with potential unknown sources of COPC. The results were utilized to provide rationale for sampling additional locations beyond those originally proposed. Most of the originally proposed sampling was driven by historical use features, such as former ASTs and associated transfer tank. Completeness is considered to be the percentage of proposed samples that were collected and analyzed. The goal for completeness was 90 percent or greater for each specific location or sample area. All sampling areas and locations achieved this goal. Comparability of the analytical results was ensured by the use of standardized USEPA analytical methods. Analysis of similar COPC was conducted using the same USEPA methods. The laboratory reporting limits for the soil sample analytical results were less than the USEPA RSLs for residential soil, except as previously discussed. 7.3 Quality Control Blanks The QC blanks employed throughout the SCS soil sampling activities included equipment and temperature blanks, each collected and/or used each day of sampling. 7.3.1 Equipment Blanks Equipment blanks were collected during each day of soil sample collection by passing deionized water through the soil sampling equipment. The equipment blanks were submitted to the laboratory for analysis of metals and VOCs. None of the equipment blanks had any reportable concentrations of metals or VOCs. 13 City of Redlands, Development Services Project No. 62934.22 May 8, 2013 7.3.2 Temperature Blanks Laboratory-prepared temperature blanks were placed in the sample ice chest to verify the level of sample preservation. The laboratory verified that the sample temperatures were equal to or less than 6°C. 7.3.3 Trip Blanks Laboratory-prepared trip blanks, using deionized water and acid preservative, were placed in the sample ice chest to verify that no cross contamination had occurred. The trip blanks were analyzed for VOCs. None of the trip blanks had reportable concentrations of VOCs. 8.0 SUMMARY, CONCLUSIONS, AND RECOMMENDATIONS Prior to the current SCS, the only known source of contamination at the parcel, based on visual observations of aurficia| soil contamination by petroleum hydrocarbons, was the area of the ASTs and transfer tank. A geophysical survey, conducted prior to field activities, revealed no underground piping outside of the area of the ASTs and transfer tank. The SCS by this firm involved the collection of sludge and water samples from the 5 ASTs and the transfer tank, the collection of 35 soil samples around the ASTs and transfer tank, and 14 soil samples over the remaining area of the Site, including the shallow drainage and storm drain inlet along Redlands Boulevard. The analytical results from the soil, sludge, and water samples indicate the following contaminants are present at reportable concentrations above the USEPA RSLs for residential soil and/or tap water: arsenic, cadmium, lead, PCBs, a SVOC (2- methylnaphthalene), a VOC (naphthalene), and zinc. Concentrations of diesel- and oil- range hydrocarbons were also reported, almost exclusively in the AST sludge, transfer tank water,'and AST area soil samples. Concentrations of arsenic, a naturally-occurring element, were reported in three of the soil samples analyzed for California Title 22 metals (total). The range of concentrations, reported from 3.67 mg/kg (boring B-20 and 6-21) to 6.62 mg/kg (boring B-17)' are above the USEPA RSL for residential soil at 0.39 mg/kg. However, this RSL is lower than most background soils in California. Also, the RSL is calculated for the lower end of the range for acceptable cancer risk at 10 '»' the upper end of 14 �� GEOTECHNICAL GROUP,ENO City of Redlands, Development Services Project No. 62934.22 May 8, 2013 which is at 10-4, which would translate to a RSL of 39 mg/kg. The 1996 Kerney Foundation Special Report, "Background Concentrations of Trace and Major Elements in California Soils," provides a range of arsenic in California soils from 0.6 to 11 mg/kg. The arsenic concentrations in the three samples from B-17, B-20, and B-21 fall within the expected background concentrations in California and the acceptable range of cancer risk. Also, these arsenic concentrations do not appear to be from any contaminant point source, and are likely associated with fill placed at the Site back in the 1930s, when the Zanja Creek was realigned to the south with the construction of Redlands Boulevard. The only sample with a lead concentration greater than the USEPA RSL for residential soil at 400 mg/kg was from soil boring B-17 at 3 feet bgs. This sample has a reported concentration of total (TTLC) lead at 661 mg/kg in the soil, above the USEPA RSL for residential soil at 400 mg/kg. It should be noted that this concentration is well less than the commercial USEPA RSL at 800 mg/kg. The elevated lead concentration, reported only at this one location at the Site, is anomalous, and most likely the result of the fill placed at the Site back in the 1930s, when the Zanja Creek was realigned to the south with the construction of Redlands Boulevard. This impacted soil may be very limited in area and depth. The concentration of TTLC lead in the 3-foot sample at boring B-17 does not exceed the level of 1,000 mg/kg for classification as a hazardous waste under California Title 22; however, no STLC analysis was conducted. If the property is to be used residentially or if the elevated lead is to be quantified for removal and disposal, then additional assessment, through a step-out approach to determine the lateral and vertical extent, should be conducted. Concentrations of two PCBs (arochlor 1016 and 1260) were reported in all of the AST sludge, transfer tank water, and some of the soil samples collected in the AST area. Only one of the sludge samples, AST-4, was reported with a concentration (2.9 mg/kg) of PCBs (Aroclor 1260) which exceeds the USEPA RSL for residential soil at 0.22 mg/kg. The transfer tank had concentrations of the PCBs Aroclor 1016 and 1260 at concentrations of 36 mg/kg and 29 mg/kg, respectively, exceeding the USEPA RSLs for tap water. The PCBs detected are most likely associated with the storage of smudge pot oil at one time in the ASTs and transfer tank. The planned removal of the sludge in the ASTs and water in the transfer tank will remove the materials with PCBs detected greater than USEPA RSLs for residential soil and tap water. 15 L©R GEOTECHNICAL GROUP,INC. City of Redlands, Development Services Project No. 62934.22 May 8, 2013 The only sample with reported concentrations of SVOCs (2-methylnaphthalene and phenanthrene) were reported in the sludge sample collected from AST-4. One of the concentrations of SVOCs (2-methylnaphthalene), reported at 298 mg/kg, exceeds the USEPA RSL for residential soil at 230 mg/kg. The SVOCs detected are apparently associated with diesel sludge present in AST-4, arid is planned for removal. The only samples with reported concentrations of VOCs (naphthalene and 1,2,4- trimethylbenzene) were reported in the sludge samples collected from AST-3 and AST-4. One of the concentrations of VOCs (naphthalene), reported at 6.8 mg/kg in the sludge sample from AST-4, exceeds the USEPA RSL for residential soil at 3.6 mg/kg. The VOCs detected are apparently associated with diesel sludge present in AST-3 and AST-4, and is planned for removal. Concentrations of diesel-range petroleum hydrocarbons up to 936,000 mg/kg and at 46.9 mg/L were reported in the AST sludge samples and transfer tank water sample, respectively. The AST sludge and transfer tank water are planned for removal. The soils around the area of the ASTs and transfer tank had reportable concentrations of petroleum hydrocarbons, in the diesel- and oil-range up to 4,910 mg/kg and up to 690 mg/kg, respectively, to a maximum depth of 15 feet bgs. As petroleum hydrocarbons are present in the soil around/near the ASTs and transfer tank, they may also be present under the ASTs and transfer tank. Based on the multi-depth samples collected and select locations, relatively low diesel- and oil-range hydrocarbon concentrations (except for the 4,910 mg/kg of diesel in the surface sample at boring B-4), and lack of lateral detection of significant hydrocarbons, suggest the presence of residual hydrocarbons that are relatively shallow and limited laterally. 16 LOR GEOTECHNICAL GROUP,INC. City of Redlands, Development Services Project No. 62934.22 May 8, 2013 Based on the SCS, the following conclusions and recommendations can be made: • The ASTs and transfer tank have free diesel product (sludge) and petroleum hydrocarbon-contaminated water. The ASTs and transfer tank have petroleum hydrocarbon-impacted soil around/near, and possibly under, them. The deepest soil sample with significant petroleum hydrocarbons was B-3-15, collected at 15 feet bgs. It is our recommendation that the ASTs and transfer tank be cleaned of all residual free product and water, which should then be transported offsite for disposal or recycling. The ASTs and transfer tank themselves, after cleaning, should then be transported offsite for recycling. After the ASTs and transfer tank have been removed, then petroleum hydrocarbon-impacted soil should be removed. The amount of petroleum impacted soil that is removed could be limited to those areas evident of diesel and oil contamination (dark, discolored soil and odor). In those areas, we would recommend the impacted soils be removed to a depth of at least 3 feet, and replaced with clean fill material. Future development of the Site will dictate further cleanup, if necessary, of petroleum hydrocarbon-impacted soil in this area. • The PCBs, SVOCs, and VOCs present in some of the samples from the ASTs and/or transfer tank appear to be associated with remnant diesel and smudge pot oil. These contaminants will be removed with the removal of the AST and transfer tank sludge and water. • The TTLC arsenic concentrations in three of the soil samples from the area of the Site away from the ASTs indicate that the arsenic is limited in area, from a non-point source, and likely associated with fill placed at the Site back in the 1930s, when the Zanja Creek was realigned to the south with the construction of Redlands Boulevard. The reported concentrations of arsenic fall within the range of expected background levels in California, and do not appear to warrant remediation. • One boring, B-17, at 3 feet bgs, is impacted with a concentration of TTLC lead exceeding the USEPA RSL for residential soil. This elevated level of lead appears to be associated with the fill placed on the Site for the Zanja Creek realignment in the 1930s. The area of lead-impacted soil appears to be small; however, if the area of the Site near boring B-17 is to be used residentially, then additional assessment of this area is warranted to confirm the lateral and vertical extent of lead-impacted soil. The assessment should obtain deeper soil samples and step-out locations from B-17 to quantify the amount of impacted soil. 17 L©R GEOTECHNICAL GROUP,INC.
