[ASI]) is pleased to submit the following Site Characterization Addendum Report (SCAR) on behalf of our client, Mr. Roger Gibson, who is the owner of the Scott's Ivy Exxon site located at 4260 Ivy Road in Charlottesville, Virginia (Figure 1). The site is currently being leased and operated by Mr. Scott Ramm, President of Wise Street Corporation. This SCAR study was required by the Virginia Department of Environmental Quality (VDEQ) following their receipt of a Phase II Subsurface Investigation and a Site Characterization Report (SCR) that documented a release of petroleum at the site. The VDEQ assigned the site PC#2013-6113 and requested the SCAR in a directive dated June 17, 2013. The Scott's Ivy Exxon site is currently being operated as a gasoline and diesel fueling station and as an automotive repair shop. Two buildings are present at the site; the southern building is used as an automotive repair shop (service building) and the northern building is a residential rental property. Gasoline and diesel fueling dispensers are present to the south of the service building. The gasoline fueling island is supplied by two active underground storage tanks (USTs). According to the VDEQ UST database, these tanks have capacities of 8,000 gallons and 12,000 gallons, and were installed in 1998. The diesel fueling dispenser is supplied by a 500-gallon aboveground storage tank (AST). The site's residential building is supplied by a heating oil UST of unknown capacity. A railroad runs along the northern boundary of the site. An aerial photograph site layout map is included as Figure 2 and an illustrated site plan map is included as Figure 3. 1.1 Summary of Previous Investigations at Subject Site Phase I Environmental Site Assessment SIG, then operating as ASI, was contracted by Mr. Scott Ramm to conduct a Phase I Environmental Site Assessment (ESA) (ASI 2013a) as part of the due diligence process for a future real estate transaction. The ESA revealed that the site has been used as a gasoline station since at least the 1950s, and possibly longer. It also revealed that there have been two documented past releases from USTs at the site. The first release was reported in February 1997 (PC#1997-5102) and the second release was reported in November 1998 (PC#1999-5133) following the removal of three 6,000-gallon gasoline USTs. Both releases have since been closed. The conclusions of the Phase I ESA included the recommendation that a Phase II Subsurface Investigation be conducted at the site. Phase II Subsurface Investi ag tion SIG, then operating as ASI, was contracted to conduct a limited Phase II Subsurface Investigation (ASI 2013b) to address concerns that were identified during the Phase I ESA. The purpose of the limited Phase II Subsurface Investigation was to provide a screening -level assessment of overburden soils and groundwater for the presence of potential contaminants at the site. -1- Site Characterization Addendum Report SIG Project No. 3361-100 Scott's Ivy Exxon August 15, 2013 The limited Phase II Subsurface Investigation revealed that the area in the vicinity of the site's gasoline UST basin had been impacted by a petroleum release, as evidenced by elevated levels of gasoline constituents in soil and groundwater samples collected hydraulically downgradient from the UST basin. An elevated concentration of total petroleum hydrocarbons (TPH) -gasoline range organics (GRO) was detected in a soil sample collected from a boring located downgradient from the UST basin, and elevated concentrations of benzene, toluene, ethylbenzene, and xylenes (BTEX) were detected in a groundwater sample collected from the same boring. The TPH-GRO concentration detected in the soil sample exceeded VDEQ UST reporting levels. Additionally, benzene, ethylbenzene, o-xylene, and total xylenes concentrations detected in the groundwater sample exceeded Virginia Voluntary Remediation Program Tier III screening levels. Limited subsurface investigation and sampling conducted at other areas of concern did not yield evidence of environmental impact at the time of the investigation and at the locations investigated. The VDEQ Valley Regional office was contacted by telephone and email, and was notified of the discovery of contamination in the vicinity of the site's UST basin. Site Characterization Study Following the results of the Phase II Subsurface Investigation, the VDEQ issued a directive dated April 17, 2013, requesting that a Site Characterization Study be conducted at the Scott's Ivy Exxon site. SIG, then operating as ASI, was contracted to conduct this study (ASI 2013c). The SCR study focused on identifying the magnitude and extent of contamination associated with a release of petroleum hydrocarbons at the site. The study included installing four monitoring wells near and downgradient from the site's UST basin. These wells (MW-1, MW-2, MW-3, and MW-4) were then surveyed, gauged, purged, sampled, and analyzed for petroleum constituents. A falling -head slug test was then conducted on MW-2 to determine the aquifer's hydraulic conductivity. Additionally, soil samples were collected and analyzed for petroleum constituents during drilling of the borings for the wells. Two surface water samples were also collected from Little Ivy Creek, and were analyzed for petroleum constituents. The subject site's domestic well was also sampled and analyzed for petroleum constituents. Elevated concentrations of petroleum contaminants were discovered at the site in the adsorbed -phase. Laboratory analysis of soil samples collected at the site during the limited Phase II Subsurface Investigation and the SCR study yielded TPH-GRO concentrations ranging between 240-1,300,000 micrograms per kilogram (µg/kg). The highest concentrations were measured in samples collected in the vicinity of the site's UST basin, although a concentration of 650 µg/kg was measured at the furthest hydraulically downgradient location (MW-4). Soil samples collected from the monitor well locations were also analyzed for TPH- diesel range organics (DRO), and the only sample to exceed laboratory detection levels was MW-1 (31 milligrams per kilogram). Elevated concentrations of TPH-GRO, total BTEX, and MTBE were discovered in groundwater samples collected during the SCR study. The highest concentrations of these constituents were measured in the vicinity of the site's UST basin, which was determined to be the most likely primary source of gasoline contamination at the site. -2- Site Characterization Addendum Report SIG Project No. 3361-100 Scott's Ivy Exxon August 15, 2013 The timing of this release is unknown. Elevated concentrations of these constituents were also measured in the furthest hydraulically downgradient well (MW-4), which is located 46 feet west of and hydraulically upgradient from Little Ivy Creek. The primary direction of groundwater contaminant plume migration was determined to be toward the east-northeast, which is comparable to the direction of groundwater flow at the site. The SCR study determined that existing contaminant concentrations posed a potential threat to human receptors, as the site's domestic supply well was found to be impacted by MTBE. It was also determined that the possibility of impact to the western adjacent property's domestic water supply well existed. Existing groundwater contaminant concentrations were also determined to pose a potential threat to Little Ivy Creek, which is located 120 feet east of the UST basin, because it is likely that groundwater from the subject site discharges to the creek. The SCR study concluded with a recommendation that an addendum to the SCR study be completed to further characterize soil and groundwater conditions at the subject site. SIG recommended the following course of action: (1) installation and sampling of additional monitor wells to further delineate upgradient and lateral extents of groundwater and soil contamination at the site; (2) installation and sampling of piezometers near Little Ivy Creek; and (3) sampling and analysis of a sample from the western adjacent property's domestic water supply well. 2.0 SITE LOCATION, HYDROLOGY, AND REGIONAL GEOLOGY The Scott's Ivy Exxon site is located at 4260 Ivy Road in Charlottesville, Virginia. The elevation of the study area portion of the subject site is approximately 514 feet above mean sea level (amsl). The subject site slopes gently to the east. The site is within the western portion of the Piedmont Physiographic Province, and is underlain by crystalline rock of the Blue Ridge Anticlinorium. Bedrock lithology beneath the site is porphyroblastic-biotite-plagioclase-augen gneiss (stratigraphic symbol Ybg), which is Middle Proterozoic (Grenville) in age (Virginia Division of Mineral Resources, 2003). Storm water drainage from the site would be expected to drain to the southeast toward Little Ivy Creek, which is located immediately adjacent to the site's southeastern boundary at a distance of 120 feet from the subject site's UST basin (Figure 2). Little Ivy Creek flows to the northeast, where it becomes a tributary to the Rivanna River. The Rivanna River supplies water to the Rivanna River Reservoir, which provides water to the City of Charlottesville, Virginia. The Rivanna River converges with the James River, which is a major tributary of the Chesapeake Bay, after flowing out of the Rivanna River Reservoir. No surface water bodies exist on the site. According to the U.S. Department of Agriculture's (USDA's) Natural Resources Conservation Service (MRCS), the Hiwassee clay loam with 7 to 15 percent slopes (soil series 42C3) underlies the northern half of the site, and the Chewacla silt loam (soil series 16) underlies the southern half of the site. The Hiwassee clay loam is generally present on 7 to 15 percent slopes and forms stream terraces. It is typically a well -drained soil, -3- Site Characterization Addendum Report SIG Project No. 3361-100 Scott's Ivy Exxon August 15, 2013 with a depth to groundwater of greater than 80 inches (USDA NRCS 2013). The Chewacla silt loam is typically present on 0 to 2 percent slopes and forms stream flood plains. It is generally a somewhat poorly -drained soil, with a depth to groundwater of 6-18 inches, depending on proximity to a stream (USDA NRCS 2013). It should be noted that depth to groundwater measurements at the site were observed to range from approximately 7-9 feet below ground surface (bgs) during this SCAR study. The Chewacla silt loam underlies the SCR study's entire area of investigation. 3.0 SOIL INVESTIGATION 3.1 Soil Sampling Methodology Prior to completing soil borings at the site, Miss Utility was contacted and a request was made for utility clearance. Due to the presence of numerous underground utilities at the site, a private utility locator was also mobilized to the site. The locations of the soil borings/wells were not marked prior to Miss Utility clearance, so it was requested that the entire site be marked. The final locations of the soil borings/wells were determined during private utility marking to ensure that the borings would not be drilled into existing utility lines. Soil sampling was conducted during the drilling of four soil borings at the site on July 12, 2013. Drilling was conducted by Certified Environmental Drilling, from Charlottesville, Virginia. A hollow -stem auger drilling rig was used to complete the borings, which were drilled to a diameter of eight inches and to total depths ranging between 15-20 feet bgs. All of the produced drill cuttings were contained and placed in 55-gallon drums. Soil cores were collected at 5-feet depth intervals with a 2-foot length, 2-inch diameter split -spoon sampler during drilling. These soil cores were logged by an SIG geologist to create geologic logs of each of the borings. Soil was collected from the cores and placed in Ziploc® bags at 5-foot intervals. The soil was then screened using a photoionization detector (PID) for the presence of volatile organic compounds (VOCs). Monitoring wells were then installed in the borings after drilling was completed (see Section 4.1). Figure 4 illustrates the locations of these wells (MW-5 through MW-8), as well as the locations of wells installed in May 2013 (MW-1 through MW-4). Appendix A includes geologic logs and well completion details for wells MW-1 through MW-8, as well as for Borings 1 and 2, which were drilled during the limited Phase II Subsurface Investigation. A soil sample was only collected from well MW-7, at a depth of 9.0-11.0 feet bgs, because this was the only screened sample to record an elevated PID reading. This sample was submitted to Phase Separation Sciences, Inc. (Phase Sciences), of Baltimore, Maryland, for laboratory analysis of TPH-GRO and TPH-DRO via EPA Method 8015B. 3.2 Soil Screening and Analytical Results PID readings of soil collected from wells MW-5 through MW-8 ranged between 0.1 and 138.2 parts per million. An elevated PID reading was only recorded in MW-7, at a depth of 9.0-11.0 feet bgs. PID readings of soil collected from wells MW-5 through MW-8 are Site Characterization Addendum Report SIG Project No. 3361-100 Scott's Ivy Exxon August 15, 2013 summarized in Table 1, below. Table 1 also contains PID readings from wells MW-1 through MW-4, which were drilled during the initial SCR investigation. Sampling results indicate that both TPH-GRO and TPH-DRO were detected in the MW-7 soil sample. At a concentration of 37,000 µg/L, the detected TPH-GRO concentration was significantly elevated. Analytical results of the aforementioned soil sampling, as well as results from the initial SCR investigation and the Phase II Subsurface Investigation, are summarized in Table 2, below. The laboratory data report and chain -of -custody documentation, as provided by Phase Separation Science, is included in Appendix B.

Elevated concentrations were discovered both hydraulically upgradient (MW-1) and downgradient (Boring 1, MW-3, MW-7) from the UST basin. Soil contamination appears to extend primarily in a downgradient direction from the UST basin. TPH-GRO soil contamination also appears to extend laterally to the south of the UST basin, but does not appear to extend north of the UST basin. TPH-DRO concentrations in soil were below laboratory detection levels in all of the borings except MW-1 and MW-7. The highest PID readings were recorded in saturated silty clay layers present at a depth of approximately 9- 15 feet bgs, which are subsequently the depths from which the majority of the soil samples were collected.

While the exact source and timing of the petroleum release is not known, a previous VDEQ pollution complaint case was assigned to the property following UST closure activities that did require the removal of petroleum impacted soil. 3.4 Localized Site Geology from Soil Cores Soil cores and drill cuttings collected during SCAR, initial SCR, and the limited Phase II Subsurface Investigation provided insight into geologic conditions at the subject site. The borings indicate that 13-20 feet of unconsolidated soil (overburden) overlies augen gneiss bedrock in the study area portion of the subject site (Appendix B). The nature and orientation of fracturing in the bedrock is unknown. The borings installed at the subject site's study area indicate that, in general, approximately 11 feet of silty -clay overlies more permeable silty -sand, sand, and/or sand and gravel layers. The permeable layers are comprised of sandy layers of variable thickness interbedded with silty -clay layers. The exact thicknesses and sediment characteristics of the permeable layers varies between the borings. Apparent bedrock outcrops exist along the western portion of the property, indicating that depth to rock may vary across the site. 4.0 GROUNDWATER INVESTIGATION 4.1 Monitor Well and Piezometer Installation WON Site Characterization Addendum Report SIG Project No. 3361-100 Scott's Ivy Exxon h August 15, 2013 Four soil borings were completed as monitoring wells at the site on July 12, 2013. These wells were designated as MW-5, MW-6, MW-7, and MW-8 (Figure 4). The well locations were selected based on groundwater contaminant data obtained during the initial SCR study, with the purpose of the wells being to further delineate the magnitude and extent of the groundwater contamination plume. Additionally, two shallow piezometers (P-1 and P- 2) were installed with a hand -auger near Little Ivy Creek on July 23, 2013. Both of these piezometers were installed on the eastern adjoining property to the subject site (Eaton property). SIG was given permission to install these piezometers by the property owner, Mr. Louis Eaton, during a phone conversation on June 28, 2013. The purpose of the piezometers was to allow for determination of whether a detectable concentration of petroleum -contaminated groundwater from the subject site was migrating to Little Ivy Creek. All of the site's monitoring wells were constructed of 2-inch diameter, threaded polyvinyl chloride (PVC) well casing and slotted screen, completed to depths ranging between 13-20 feet bgs (Table 3). The bottom 10 feet of each well is comprised of slotted screen, with blank casing comprising the remainder of the well. The wells were completed in the following manner: (1) the well's screen and casing were placed in the open borehole; (2) the annular space around the screen and casing was filled with #2 or #3 silica sand from the bottom of the boring to a depth of 1-2 feet above the top of the well screen; (3) a 1-foot thick layer of bentonite pellets was placed above the silica sand; (4) the remaining annular space was grouted, and flush -mounted well covers were cemented in place. Illustrations of the individual well completions are included with the Appendix A geologic logs. Both of the site's piezometers were installed in 3-inch diameter hand-augered borings. They were constructed of 2-inch diameter, threaded PVC well casing and slotted screen. Completion depths of P-1 and P-2 were 6.78 feet bgs and 8.27 feet bgs, respectively. The bottom four feet of both piezometers are comprised of slotted screen, with blank casing comprising the remainder of the piezometers. The annular space around the screen and casing was filled with #3 silica sand, from the bottom of the boring to approximately one foot bgs. Bentonite pellets were then used to fill the annular space from the top of the sand to the ground surface. Both piezometers were completed with 1-2 feet of casing stickup and a locking cap. On July 23, 2013, the distances from P-1 and P-2 to the water surface of Little Ivy Creek were 21 feet and eight feet, respectively. The relative elevations of the new monitoring wells' and piezometers' top -of -casings (TOCs) were surveyed in reference to MW-1 through MW-4 TOC elevations, which had been surveyed at the site during SCR activities. The benchmark utilized to survey MW-1 through MW-4 was the northeastern corner of the UST basin's easternmost rectangular fuel -fill access box, which was assumed to have an elevation of 514.00 feet amsl, based on Google Earth elevation data. Additionally, the elevations of Little Ivy Creek's water surface at points directly adjacent to P-1 and P-2 were measured. TOC elevations of all monitoring wells and piezometers, as well as the total depths of the wells, are included in Table 3, below. -7- Site Characterization Addendum Report SIG Project No. 3361-100 Scott's Ivy Exxon August 15, 2013 Table 3 Summary of Well, Piezometer, and Little Ivy Creek Gauging Results Gauging Location Total Well Depth (feet bgs) TOC Elevation (feet amsl) Date Gauged Depth to Water from TOC (feet) Product Thickness (feet) Groundwater Elevation (feet amsl) MW-1 15 514.29 5/16/2013 9.55 0 504.74 5/28/2013 9.82 0.01 504.47 7/23/2013 9.29 0 505.00 MW-2 14 513.25 5/16/2013 8.78 0 504.47 5/28/2013 9.08 0 504.17 7/23/2013 8.54 0 504.71 MW-3 13 513.39 5/16/2013 8.66 0 504.73 5/28/2013 9.07 0 504.32 7/23/2013 8.57 0 504.82 MW-4 14 513.15 5/16/2013 9.09 0 504.06 5/28/2013 9.32 0 503.83 7/23/2013 8.89 0 504.26 MW-5 20 512.23 7/23/2013 7.31 0 504.92 MW-6 15 513.20 7/23/2013 8.26 0 504.94 MW-7 15 514.29 7/23/2013 9.43 0 504.86 MW-8 15 514.14 7/23/2013 7.93 0 506.21 P-1 6.78 509.83 7/23/2013 5.81 0 504.02 7/31/2013 5.96 0 503.87 P-2 8.27 509.85 7/23/2013 6.51 0 503.34 7/31/2013 6.45 0 503.40 LIC, adjacent to P-1 NA NA 7/23/2013 NA 0 503.50 7/31/2013 0 503.45 LIC, adjacent to P-2 NA NA 7/23/2013 NA 0 503.43 7/31/2013 0 503.50 bgs = below ground surface; TOC = top -of -casing; amsl = above mean sea level; LIC = Little Ivy Creek; NA = not applicable 4.2 Groundwater Sampling SIG personnel returned to the Scott's Ivy Exxon site on July 23, 2013 to gauge, develop, and collect samples from all of the site's monitoring wells. SIG determined the relative groundwater elevations in the wells by first measuring the depth -to -water (DTW) in the wells. The DTW value was then subtracted from the well's TOC elevation, yielding the Site Characterization Addendum Report SIG Project No. 3361-100 Scott's Ivy Exxon August 15, 2013 elevation of groundwater in the well. Table 3 below summarizes the resulting groundwater elevations, as well as the elevations of Little Ivy Creek's water surface at points directly adjacent to P-1 and P-2. Table 3 also includes groundwater elevations in P- 1 and P-2 and water surface elevations in Little Ivy Creek near these piezometers, which were re -measured on July 31, 2013. Based on the groundwater elevations measured during the July 23, 2013 sampling event, a groundwater equipotential map was created and is included as Figure 6. The map shows that groundwater flow direction at the site is influenced by the presence of Little Ivy Creek. The groundwater equipotential lines exhibit the pattern of a typical gaining -stream hydraulic setting, where groundwater discharges to a surface stream. The range of water table fluctuation at the site is not well known, due to a limited number of monitoring events. However, it was observed that groundwater levels in wells MW-1 through MW-4 were approximately 0.5 feet higher than levels measured on May 28, 2013. Free product was observed in MW-1 during the May 28, 2013 well gauging event (Table 3). Although free product was not observed in MW-1 during the July 23, 2013 well gauging event, product globules and a significant sheen were noted on the surface of MW- 1's purge water. A minimum of three well volumes of water was purged from each well prior to collecting groundwater samples. Groundwater samples were then collected from all of the wells using disposable bailers, and were placed in a refrigerated cooler. A duplicate sample was collected from MW-2, and was labeled as Field Duplicate. Samples collected from the monitoring wells were submitted to Phase Sciences for laboratory analysis of TPH-GRO via EPA method 8015B, BTEX via EPA method 8021B, and methyl tert-butyl ether (MTBE) via EPA method 8021B. Samples collected from the piezometers were submitted for laboratory analysis of VOCs via EPA method 8260B. A groundwater sample was also collected from the subject site's domestic well on July 23, 2013. Additionally, upon receiving authorization from Mr. Joseph Richmond, the owner of the western adjoining property, the domestic well on the Richmond property (Richmond Well) was sampled on July 31, 2013. The locations of the subject site's domestic well and the Richmond Well are shown in Figure 2. Both samples were submitted to Phase Sciences for laboratory analysis of VOCs via EPA method 8260B. 4.3 Groundwater Analytical Results Groundwater samples collected from the site's monitoring wells were submitted for laboratory analysis of TPH-GRO, total BTEX, and MTBE. The resulting analytical data showed that these constituents were detected at concentrations exceeding laboratory detection levels in samples collected from all of the site's monitor wells except MW-5 and MW-8. TPH-GRO concentrations ranged from below laboratory detection levels to 18,000 µg/L. Total BTEX concentrations ranged from below laboratory detection to 4,489 µg/L. MTBE concentrations ranged from below laboratory detection level to 65 µg/L. The highest concentrations of all of these constituents were measured in MW-I. Site Characterization Addendum Report SIG Project No. 3361-100 Scott's Ivy Exxon August 15, 2013 Groundwater samples were collected from both piezometers installed along the banks of Little Ivy Creek, and were submitted for laboratory analysis of VOCs. Analytical results showed that VOC concentrations in P-1 were below laboratory detection levels for all analyzed constituents. VOC concentrations in P-2 were below laboratory detection levels for all analyzed constituents except MTBE, which had a concentration of 1.1 µg/L. Groundwater samples collected from the subject site's domestic well and the adjoining Richmond Well were collected and submitted for laboratory analysis of VOCs. It should be noted that the VDEQ's water treatment contractor (Culligan) installed treatment equipment at the site that was in place prior the SCAR sampling event. In the sample collected from the subject site's domestic well, all analyzed VOC constituents were below laboratory detection levels except chloromethane, which had a concentration of 2.9 µg/L. In the sample collected from the Richmond Well, all analyzed VOC constituents were below laboratory detection levels except MTBE, which had a concentration of 6.0 µg/L. Analytical results yielded from groundwater sampling of the monitor wells, piezometers, and domestic water supply wells are summarized in Table 4, below. Additionally, groundwater sampling results from the initial SCR study and limited Phase II Subsurface Investigation are included in this table. Laboratory certifications and chain -of -custody documentation from the SCAR sampling event are included in Appendix B. 4.4 Discussion of Groundwater Analytical Results The installation of wells MW-5 through MW-8, as well as piezometers P-1 and P-2, provided improved insight into groundwater flow at the site. Shallow groundwater flow direction at the site during the July 2013 sampling event, as determined by gauging data from the monitor wells and piezometers, is toward the east-southeast (Figure 6). Groundwater appears to be flowing directly toward Little Ivy Creek, in a more easterly - southeasterly direction than initially thought during the SCR study. Installation of the piezometers has lead to an improved understanding of groundwater - surface water interactions between the shallow groundwater system and Little Ivy Creek. Groundwater elevations in the piezometers and surface water elevations in Little Ivy Creek at locations adjacent to the piezometers were determined on two separate occasions (July 23, 2013 and July 31, 2013). Both monitoring events yielded similar results; the groundwater elevation in P-1 was approximately 0.5-foot higher than the adjacent Little Ivy Creek water surface elevation, and the groundwater elevation in P-2 was approximately 0.1-foot lower than the adjacent Little Ivy Creek water surface elevation. -10- Site Characterization Addendum Report SIG Project No. 3361-100 Scott's Ivy Exxon August 15, 2013 Table 4 Summary of Groundwater Sampling Analytical Results Well ID Sampling Date Benzene (µg�L) Toluene (Ng�L) Ethyl- benzene (Ng/L) Total Xylenes (Ng/L) Total BTEX (Ng/L) TPH- GRO (µg/L) MTBE (µg/L) Chloro- methane (µg/L) MW-1 5/16/2013 73 <10 4,700 510 5,283 17,000 1 95 NA 7/23/2013 58 11 3,900 520 4,489 18,000 65 NA MW-2 5/16/2013 4.0 <1.0 10 6.4 20.4 520 8.5 NA 7/23/2013 4.3 <1.0 1.0 5.1 10.4 780 10 NA Field Duplicate (MW-2) 7/23/2013 3.7 <1.0 1.0 5.2 9.9 630 8.1 NA MW-3 5/16/2013 21 <1.0 47 16.2 84.2 1,800 25 NA 7/23/2013 13 <1.0 53 15.1 81.1 1,600 14 NA MW-4 5/16/2013 31 <1.0 33 15.5 79.5 1,600 14 NA 7/23/2013 30 <1.0 25 15.8 70.8 2,400 15 NA MW-5 7/23/2013 <1.0 <1.0 <1.0 <3.0 <6.0 <100 <1.0 NA MW-6 7/23/2013 <1.0 <1.0 <1.0 <3.0 <6.0 <100 5.7 NA MW-7 7/23/2013 44 14 110 135.8 303.8 3,600 21 NA MW-8 7/23/2013 <1.0 <1.0 <1.0 <3.0 <6.0 <100 <1.0 NA P-1 7/23/2013 <1.0 <1.0 <1.0 <3.0 <6.0 NA <1.0 <1.0 P-2 7/23/2013 <1.0 <1.0 <1.0 <3.0 <6.0 NA 1.1 <1.0 Scott's Ivy Domestic 5/28/2013 <1.0 <1.0 <1.0 <3.0 <6.0 NA 20 <1.0 Well 7/23/2013 <1.0 <1.0 <1.0 <3.0 <6.0 NA <1.0 2.9 Richmond Domestic Well 7/31/2013 <1.0 <1.0 <1.0 <3.0 <6.0 NA 6.0 <1.0 Boring 1 3/21/2013 210 180 4,200 12,470 17,060 NA NA NA µg/L = micrograms per liter or parts per billion; BTEX = benzene, toluene, ethylbenzene, and xylenes; TPH-GRO = total petroleum hydrocarbons -gasoline range organics; MTBE = methyl tert-butyl ether; NA = not analyzed for this constituent The relationship between P-1 and the creek indicates that groundwater is being discharged to the creek (i.e. gaining -stream system), and the relationship between P-2 and the creek indicates that surface water is being discharged to the groundwater system (i.e. losing - stream system). Prior to collecting gauging data from the piezometers, it was expected that gauging data would indicate the presence of a gaining -stream system at both locations, as groundwater at the site flows toward Little Ivy Creek. A possible explanation for the losing -stream system observed near P-2 is that Little Ivy Creek has incised to bedrock at this stream gauging location, which has slowed incision and resulted in an elevated stream -11- Site Characterization Addendum Report SIG Project No. 3361-100 Scott's Ivy Exxon August 15, 2013 level. The uneven bedrock surface observed during monitoring well installation makes it possible for a short section of the creek to have incised to bedrock while other sections of the creek have not. The relationship between P-2's groundwater level and the elevation of Little Ivy Creek adjacent to P-2 should be monitored during future sampling events. Elevated concentrations of dissolved -phase TPH-GRO, total BTEX, and MTBE were detected in samples collected during SCAR sampling. Isoconcentration maps of dissolved - phase benzene, total BTEX, and MTBE were developed to aid in contaminant plume analysis, based on analytical data collected during the July 2013 sampling event (Figures 7, 8, and 9, respectively). The resulting MTBE concentrations from the site's domestic well and the Richmond Well were not included in Figure 9 because these wells were completed in fractured bedrock, whereas the monitoring wells were completed in overburden. The general direction of contaminant plume migration appears to follow groundwater flow direction, toward the east-southeast. The highest concentrations of these constituents were measured in MW-1. The total BTEX concentration measured in MW-1 was significantly higher than concentrations measured in any of the other monitoring wells. The additional monitoring wells and piezometers installed during the SCAR study have aided in defining the extent of contamination at the site. The upgradient, north -lateral, and downgradient extents of contamination appear to be well defined, although the full downgradient extent of MTBE is unknown, as MTBE was detected in the furthest downgradient monitoring location (P-2). The south -lateral extent of contamination remains unknown, as elevated contaminant concentrations were measured in the furthest south monitoring well (MW-7). MTBE was detected in the subject site's domestic well during the initial SCR study at a concentration of 20 µg/L, and also during a separate sampling event conducted on June 25, 2013 by the VDEQ's water treatment contractor, at a concentration of 14.9 µg/L (Appendix B). The SCAR sample from the site's domestic well was collected "downstream" of the treatment equipment and MTBE was not detected. Chloromethane was detected at a concentration of 2.9 µg/L. The source of the Chloromethane is unknown, but could potentially be associated with any chlorination activity that may have occurred as part of the water treatment equipment installation, as chlorination of petroleum -impacted water can generate chloromethane as a byproduct (U.S. Department of Health and Human Services 1998). MTBE was also detected in the adjacent Richmond Well at a concentration of 6.0 µg/L. This detection, along with the documented presence of MTBE in the subject site's domestic well, suggests that contamination has migrated to the deeper, fractured bedrock aquifer into which these wells are completed. Contaminant levels detected in the Field Duplicate sample, which was a duplicate sample collected from MW-2, were within 19% of concentrations measured in the MW-2 sample for all analyzed constituents. The analyzed Field Duplicate concentrations differed from the MW-2 concentrations by the following percentage differences: benzene -14%, toluene 0%, ethylbenzene 0%, total xylenes +2%, TPH-GRO 19%, and MTBE -19%. -12- Site Characterization Addendum Report SIG Project No. 3361-100 Scott's Ivy Exxon E August 15, 2013 5.0 FINDINGS AND RISK ASSESSMENT This SCAR study focused on building upon work completed during the initial SCR study, with the focus being to further identify the magnitude and extent of contamination associated with a release of petroleum hydrocarbons at the Scott's Ivy Exxon site. Work completed as part of the SCAR study included the installation of an additional four monitoring wells, the installation of two shallow piezometers near Little Ivy Creek, gauging and sampling of monitoring wells and piezometers, and sampling of the subject site's domestic well and the adjacent Richmond Well. Adsorbed -phase (Figure 5) and dissolved -phase (Figures 7, 8, and 9) isoconcentration maps were prepared to estimate the areal extent of impacted soil and groundwater at the subject site. Adsorbed -phase contaminant concentrations indicate that "hot spots" are present immediately surrounding the UST basin. These hot spots exhibit significantly elevated TPH-GRO concentrations, while nearby sampled locations exhibit concentrations that were either detected at low concentrations or were below laboratory detection levels. The hot spots that have been found to contain the highest concentrations of adsorbed -phase TPH- GRO were at the location of Boring I and MW-1. The exact source and timing of the petroleum release is unknown. A previous DEQ pollution complaint case was assigned to the property in 1998 and was later closed. Work conducted during the case's active status included excavation of petroleum impacted soil. Dissolved -phase isoconcentration mapping revealed that groundwater contamination consisting of elevated levels of benzene, total BTEX, and MTBE appears to have migrated from the subject site and onto the eastern adjoining property. The additional monitoring locations installed as part of the SCAR study aided in plume delineation, as the upgradient, north -lateral, and downgradient plume extents appear to be fairly well- defined. However, the south -lateral plume extent has not yet been defined, as elevated contaminant concentrations were measured in the westernmost monitoring well (MW-7). Of the dissolved -phase petroleum constituents detected at the site, the MTBE contamination plume appears to have migrated the furthest onto the eastern adjoining property, as MTBE was detected in the furthest downgradient monitoring location (P-2). Little Ivy Creek appears to be a gaining -stream system at the location of (P-2), which could enable a direct pathway for migration of contaminated groundwater to be discharged into the creek. MTBE has been documented in groundwater samples collected from the subject site's domestic well. Based on the presence of MTBE contamination, the VDEQ had water treatment equipment installed at the site. Additionally, MTBE was detected in a groundwater sample collected from the adjacent Richmond Well during this SCAR study. Although groundwater flow direction in the shallow, unconsolidated aquifer beneath the subject site has been established, groundwater flow direction in the deeper, fractured bedrock aquifer is unknown. Based on this lack of information, it is unknown whether the source of contamination in the fractured bedrock aquifer is from a release of petroleum on the subject property or from a different source. Based on the relatively -13- Site Characterization Addendum Report SIG Project No. 3361-100 Scott's Ivy Exxon August 15, 2013 shallow depth to weathered rock (saprolite) encountered during installation of MW-8 and the presence of apparent bedrock outcrops observed along the western portion of the site, the potential for petroleum contamination identified near the existing UST fuel system to impact the bedrock aquifer does exist. The highest concentrations of both dissolved -phase and adsorbed -phase petroleum compounds were found in the vicinity of the subject site's UST basin and fuel dispensers. Although the timing of the release is unknown, the size of the dissolved -phase contaminant plumes and the weathered appearance of product globules purged from MW-1 during both the SCR and SCAR studies indicate that the release may have occurred years ago. Based on data obtained during the limited Phase II Subsurface Investigation, the initial SCR study, and this SCAR study, existing contaminant concentrations appear to pose a potential threat to human receptors, as the site's domestic supply well and the adjacent Richmond Well were found to be impacted by MTBE. Existing groundwater contaminant concentrations also appear to pose a threat to Little Ivy Creek, which is located 120 feet east of the UST basin. Detection of MTBE in the furthest downgradient monitoring location, which is located within 10 feet of Little Ivy Creek, indicates that low levels of MTBE may be discharging to the creek. 6.0 CONCLUSIONS SIG has conducted a SCAR at the Scott's Ivy Exxon site, located at 4260 Ivy Road in Charlottesville, Virginia. Based on data acquired through groundwater and soil sampling, laboratory analysis, and a review of published geologic and topographic data, SIG concludes the following: 1. A release of petroleum has impacted soil and groundwater at the Scott's Ivy Exxon site. The highest concentrations of both adsorbed- and dissolved -phase contamination appears to be present in the vicinity of the subject site's UST basin and fuel dispensers. The exact source and timing of the release are unknown. While the upgradient, north -lateral, and downgradient extents of both adsorbed- and dissolved -phase contamination have been defined, the south -lateral extent of contamination remains unknown at this time. 2. Groundwater wells are utilized in the area for domestic water supply. Sampling of the subject site's domestic well and the adjacent Richmond Well have shown that both wells have been impacted by MTBE. 3. Contaminated groundwater from the subject site has migrated onto the eastern adjoining property, and appears to pose a threat to Little Ivy Creek, based on a detection of MTBE in a piezometer located within 10 feet of the creek. -14- Site Characterization Addendum Report SIG Project No. 3361-100 Scott's Ivy Exxon August 15, 2013 7.0 RECOMMENDATIONS Based on the findings of this SCAR study, SIG recommends that actions be taken to protect human and environmental receptors vulnerable to contamination originating from the subject site. SIG recommends that a Corrective Action Plan (CAP) be developed for the site to address these actions. The CAP would identify measures designed to provide clean drinking water to impacted supply wells, protect groundwater quality within the bedrock aquifer, and protect water quality within Little Ivy Creek. The site vicinity is not serviced by public water, based on discussions with the Albemarle County Service Authority. Therefore, the feasibility of installing alternate water supply wells would be evaluated in the CAP. The CAP would also present a strategy for protecting the bedrock aquifer and Little Ivy Creek from contamination originating from the subject site. Both passive and active remedial methods would be evaluated in the CAP. SIG also recommends further monitoring of contaminant levels at the site. Monitoring wells and piezometers should be sampled on a quarterly basis to evaluate dissolved -phase contaminant migration. Additionally, the subject site's domestic well and the Richmond Well should be sampled during these monitoring events to monitor VOC concentrations in the fractured bedrock aquifer that supplies drinking water to their respective properties. 8.0 LIMITATIONS The work performed in conjunction with this project, and the data developed, are intended as a description of available information at the sample locations indicated and the dates specified.

Any sample conditions not in compliance with sample acceptance criteria are described in Case Narrative Summary. Notes: 1. The presence of a common laboratory contaminant such as methylene chloride may be considered a possible laboratory artifact. Where observed, appropriate consideration of data should be taken. 2. The following analytical results are never reported on a dry weight basis: pH, flashpoint, moisture and paint filter test. 3. Drinking water samples collected for the purpose of compliance with SDWA may not be suitable for their intended use unless collected by a certified sampler [COMAR 26.08.05.07.C.2]. 4. The analyses of 1,2-dibromo-3-chloropropane (DBCP) and 1,2-dibromoethane (EDB) by EPA 524.2 and calcium, magnesium, sodium and iron by EPA 200.8 are not currently promulgated for use in testing to meet the Safe Drinking Water Act and as such cannot be used for compliance purposes. The listings of the current promulgated methods for testing in compliance with the Safe Drinking Water Act can be found in the 40 CFR part 141.1, for the primary drinking water contaminates, and part 141.3, for the secondary drinking water contaminates. 5. The analyses of chlorine, pH, dissolved oxygen, temperature and sulfite for non -potable water samples tested for compliance for Virginia Pollution Discharge Elimination System (VDPES) permits and Virginia Pollutant Abatement (VPA) permits, have a maximum holding time of 15 minutes established by 40CFR136.3.

Any sample conditions not in compliance with sample acceptance criteria are described in Case Narrative Summary. Notes: 1. The presence of a common laboratory contaminant such as methylene chloride may be considered a possible laboratory artifact. Where observed, appropriate consideration of data should be taken. 2. The following analytical results are never reported on a dry weight basis: pH, flashpoint, moisture and paint filter test. 3. Drinking water samples collected for the purpose of compliance with SDWA may not be suitable for their intended use unless collected by a certified sampler [COMAR 26.08.05.07.C.2]. 4. The analyses of 1,2-dibromo-3-chloropropane (DBCP) and 1,2-dibromoethane (EDB) by EPA 524.2 and calcium, magnesium, sodium and iron by EPA 200.8 are not currently promulgated for use in testing to meet the Safe Drinking Water Act and as such cannot be used for compliance purposes. The listings of the current promulgated methods for testing in compliance with the Safe Drinking Water Act can be found in the 40 CFR part 141.1, for the primary drinking water contaminates, and part 141.3, for the secondary drinking water contaminates. 5. The analyses of chlorine, pH, dissolved oxygen, temperature and sulfite for non -potable water samples tested for compliance for Virginia Pollution Discharge Elimination System (VDPES) permits and Virginia Pollutant Abatement (VPA) permits, have a maximum holding time of 15 minutes established by 40CFR136.3. Standard Flags/Abbreviations: B A target analyte or common laboratory contaminant was identified in the method blank. Its presence indicates possible field or laboratory contamination. C Results Pending Final Confirmation. E The data exceeds the upper calibration limit; therefore, the concentration is reported as estimated. Fail The result exceeds the regulatory level for Toxicity Characteristic (TCLP) as cited in 40 CFR 261.24 Table 1. J The target analyte was positively identified below the reporting limit but greater than the LOD. LOD Limit of Detection. An estimate of the minimum amount of a substance that an analytical process can reliably detect. An LOD is analyte and matrix specific. ND Not Detected at or above the reporting limit.
