8 AECOM City of Guelph 20 Annual Groundwater Monitoring Report Former IMICO Site. Introduction and Background The City of Guelph retained AECOM to undertake groundwater monitoring activities throughout 20 at the Former International Malleable Iron Company (IMICO) site (the Site) located at 200 Beverly Street, Guelph, Ontario (Figure ). Currently the Site is owned by the City of Guelph. The site is approximately 5.2 ha (3 acres) in size and is currently inactive. Prior to 989, the Site operated as a foundry. Since that time all structures have been decommissioned and demolished. A preliminary site assessment and investigation was completed in 989 and 99 by Proctor & Redfern that identified several subsurface contaminants present at the Site (Proctor & Renfern, 99a; Proctor & Renfern, 99b). Reports identified various metals, petroleum hydrocarbons (PHCs), volatile organic compounds (VOCs), and polynuclear aromatic hydrocarbons (PAHs) in soil and groundwater at concentrations above the Ministry of the Environment (MOE) standards. In 994 Provincial Orders were placed on the site under the Environmental Protection Act Sections 7, 8, 43 and 97. The Order identified contaminated areas that existed at the site and ordered that work be completed to investigate and remediate contamination. A hydrogeologic site investigation completed by Gartner Lee Limited (now AECOM) in 998 identified several locations where groundwater and soil concentrations exceeded the applicable standard for zinc, lead, PHCs, VOCs, and PAHs. In 2004, Provincial Officer s Order (Order Number 766-5LAL3S) were received for Former IMICO site. As per the Order, groundwater monitoring wells were drilled at 490 York Road, adjacent to the Site. Hydraulic testing and groundwater monitoring were completed on the newly installed wells OW28S, OW28D, OW29S, OW29D, OWS, and OWD. Results demonstrated that concentrations of trichloroethylene (TCE) and various PHCs above the MOE standards continued to be present in the soil and groundwater at the Site (GLL, 2004). The report also concluded that the TCE concentrations found on Site were likely coming from the general vicinity of well nest OW, located at 490 York Road. A Phase I and Phase II Environmental Site Assessment, and a preliminary Remedial Action Plan (RAP) were completed in 2007 by Decommissioning Consulting Services Limited (DCS). The RAP recommended several potential remedial options, one of them included conducting a risk assessment (RA) for industrial/commercial/community use, and to sever the property to allow for more immediate usage where contamination is no longer present or that an RA determines to be acceptable. Semi-annual groundwater monitoring and quarterly water levels have been obtained by AECOM since 998. In 20, the groundwater monitoring events occurred in June and September. Groundwater levels were also recorded in December 20. This report presents results from all groundwater monitoring that occurred in Geologic Setting The surficial geology of the Site is comprised of fill material that is approximately.4 m to 3.2 m in thickness and includes foundry sand and slag, underlain by native silty fine sand till, underlain by dolostone bedrock. The sand layer ranges in thickness from m in the western portion of the property to 3. m in the southeastern portion of the property. The upper portion of the dolostone bedrock is considered to be highly fractured and therefore porous. The depth of bedrock ranges from.4 m (at OW2) to 3.2 m (OW8-II) below ground surface. The average hydraulic Former IMICO 20 Annual Groundwater Monitoring Report -FINAL.Docx

9 AECOM City of Guelph 20 Annual Groundwater Monitoring Report Former IMICO Site conductivity measured in the shallow monitoring wells ranges from 3.2 x 0-6 m/s to 2.5 x 0-4 m/s. The hydraulic conductivity for the monitoring wells screened in bedrock is approximately 5.0 x 0-6 m/s. Monitoring wells installed at the Site are completed into two groundwater zones (shallow and deep) that appear to have differing groundwater chemistry. The shallow zone is composed of overburden and shallow, highly fractured bedrock. The deep zone is composed of deeper more competent bedrock at a depth of at least.5 m below grade. 3. Methods Prior to commencing groundwater monitoring events and recording water levels, the monitoring wells were opened and allowed to equilibrate with atmospheric pressure. This was completed to ensure that water level measurements were representative of the hydraulic head in the respective wells. Groundwater monitoring occurred June 6 and 7 and September 9 and 20, 20. Groundwater levels were also recorded on December 5, 20. Groundwater and product levels were recorded using an electronic interface level tape in June, and a water level tape in September and December, 20. The interface and water level tapes were decontaminated between each well with a liquinox and water solution, followed by methanol, and rinsed with distilled water. Groundwater levels were measured from the top of the monitoring pipe at all accessible monitoring wells at the Site, along the property boundary, on Beverly Road, at 490 York Road, along the Guelph Junction Railway, and on Simcoe Street. Groundwater levels were all converted to an elevation in meters above sea level (masl) using reference elevations. The following monitoring wells were sampled: Shallow Monitoring Wells: OW2, OW6, OW9-I, OW0, OW-I, OW2, OW6, OW8-I, OW9, OW22S, OW23S, OW24S, OW25, OW26S, OW27S, OW28S, OW29S, OWS. Deep Monitoring Wells: OW9-II, OW-II, OW3, OW4, OW8-II, OW22D, OW23-D, OW24D, OW25, OW26D, OW27D, OW28D, OW29D, OWD. Groundwater samples were collected from each well using dedicated inertial lift valves. During the sampling event, a water quality instrument was used to measure water quality parameters that included ph, oxidation reduction potential, dissolved oxygen, specific conductivity and temperature following every well volume that was purged. A groundwater sample was collected following the removal of three well volumes. All purge water was stored in labelled drums for subsequent handling and removal by the City of Guelph. AECOM staff wore nitrile gloves throughout each sampling event and changed the gloves between each monitoring well location. Groundwater samples were submitted to MAXXAM Analytics (MAXXAM) under a chain of custody (CoC) protocol and analyzed for parameters listed in Table B-, Appendix B. Groundwater chemistry results were compared to the standards published in Ontario Regulation 53/04 Table 2 (as amended) for potable groundwater, in an Industrial/Commercial/Community property use with coarse textured soils (herein referred to as the applicable standard ) Former IMICO 20 Annual Groundwater Monitoring Report -FINAL.Docx 2

10 AECOM City of Guelph 20 Annual Groundwater Monitoring Report Former IMICO Site 4. Monitoring Results 4. Groundwater Flow Regional topography is characterized by broad, oval-shaped rolling hills separated by poorly drained valleys, with local relief, generally sloping less than 5 m towards the south. The Site is approximately 800 m north of the Eramosa River. Groundwater contour maps were generated for shallow and deep groundwater zones for each event. The shallow groundwater zone is defined by monitoring wells that are screened in the overburden, and across the bedrock contact. The deeper groundwater zone is defined by monitoring wells screened across fractured bedrock. Groundwater and interface levels are presented in Table A-. Potentiometric contour maps representing groundwater flow at the Site are included in Figure 2 and 3. Monitoring wells OW07-33, OW07-34D, OW07-37, OW27S and OW28S have been excluded from potentiometric contour maps as they are screened in bedrock and the sand pack extends to the overburden. Therefore the water levels in the monitoring wells are mixing shallow and deep groundwater zones and are not comparable to other monitoring wells. The groundwater flow direction in the shallow zone is southerly, with a change in hydraulic head across the site of.0 m in June 20, 0.62 m in September 20, and 0.70m in December 20. In the deeper groundwater zone there is consistently hydraulic high near OW23D, and groundwater flowing away from this high during 20. The greatest changes in hydraulic heads in the deeper zone were.7 m from OW23D to OWD in June 20, 3 m from OW8-II to OW-II in September 20, and 0.82 m from OW23D to OW-II in December 20. Vertical hydraulic gradients were downward across the study area in 20, which is consistent with previous years. A 2004 report by Gartner Lee Limited indicated that Holody Electro Plating is located approximately 500 m to the northeast has a large capacity industrial well, and the water takings (which is currently unknown) may locally influence groundwater flow in the deep bedrock zone. At OW23S a light non-aqueous phase liquid was measured and ranged between 0.04 m to 0.5 m thickness over the four monitoring events in Groundwater Chemistry Results Groundwater chemistry results are included in Appendix B from the 20 monitoring events. Historical concentration figures for selected metals, volatile organic compounds (VOCs) polyaromatic hydrocarbons (PAHs), and petroleum hydrocarbons (PAHs) are presented in Figures 4 through Inorganic Parameters Inorganic groundwater results were below the applicable standard with the exception zinc at the following locations: OW6 (3,0 µg/l,,500 µ/l) OW9-I (,500 g/l, 2,000 g/l) OW3 (,500 µg/l,,900 µg/l) OW4 (2,00 µg/l, 3,200 µg/l) OW8-I (,00 µg/l,,0 µg/l) OW22S (2,900 µg/l, 4 g/l) OW24S (740 g/l,,0 g/l) Former IMICO 20 Annual Groundwater Monitoring Report -FINAL.Docx 3

11 AECOM City of Guelph 20 Annual Groundwater Monitoring Report Former IMICO Site Lead was detected slightly above the applicable standard at OW9-II at 6 g/l (June) and g/l (September) which is consistent with historical results. Overall, inorganic results were consistent with 200 data. Arsenic was reported to be above the applicable standard during initial investigations in 998, however concentrations have been at or near the laboratory detection limit for over 5 years. Therefore, arsenic is no longer considered a contaminant of concern at the Site. All other monitoring wells sampled for inorganic parameters during the program were below the applicable standard Volatile Organic Compounds (VOCs) VOCs of concern at, and within the vicinity of, the Site are trichloroethylene (TCE) and its respective degradation products including cis-,2-dichloroethylene (cis-,2-dce),,-dichloroethylene (,-DCE) and vinyl chloride (VC).,,-TCA has also been detected above the applicable standard. TCE concentrations were above the MOE standard at several monitoring wells primarily located at the eastern portion of the Site and at 490 York Street. Monitoring wells that exceeded the applicable standard for TCE in June and/or September 20, respectively included: OW25 (.8 g/l, 2.3 g/l) OW6 (0.9 g/l, and 2.2 g/l) OW8-I (9.5 µg/l, 0 µg/l) OW8-II (3.3 µg/l,.0 µg/l) OW23D (.6 µg/l,.4 µg/l) OW24S (64 µg/l, 76 µg/l) OW24D (3,400 µg/l, 5,0 µg/l) OW27S (4 µg/l, µg/l) OW28S (Not sampled, 40 µg/l) OW28D (8 µg/l, 2 µg/l) OW29S (50 µg/l, 200 µg/l) OW29D (900 µg/l,,000 µg/l) OWS (970 µg/l, 8 µg/l) OWD (Not sampled, 4,600 g/l) TCE concentrations for selected monitoring wells are depicted in Appendix B. TCE concentrations in 20 were generally higher at deep monitoring wells than at shallow locations. Also, TCE at the shallow monitoring wells generally appears to be decreasing in concentration. The presence of downward gradients at the eastern portion of the Site along with the trend of increasing TCE concentration in the deeper (bedrock) aquifer suggests that TCE is migrating from the shallow aquifer to the deeper (bedrock) aquifer in this area of the Site. The highest concentrations of TCE observed in 20 were 4,600 g/l (September) at OWD (located at 490 York Road) and at OW24D (located at the eastern portion of the Site) with concentrations of 3,400 g/l (June) and 5,0 g/l (September). Concentration versus time plots for selected monitoring wells including OW8, OW24, OW29 and OW are presented in Appendix B. Concentrations of TCE have stabilized over time at OW8-II, OW24S, OW29S, OW29D, OWS. At OW24D TCE concentrations appear to be on an increasing trend in 200 and 20, additional data is required to confirm whether the concentration of 5,0 g/l was an anomaly. At OW28S, TCE concentrations appear to vary between seasons where lower concentrations are detected in the spring/summer and higher concentrations of TCE are detected in the fall.,-dce, cis-,2-dce, trans-,2-dce, and VC were detected in several monitoring wells across the study area above the applicable standard at locations that historically had detections of TCE or are located downgradient of Former IMICO 20 Annual Groundwater Monitoring Report -FINAL.Docx 4

12 AECOM City of Guelph 20 Annual Groundwater Monitoring Report Former IMICO Site monitoring wells with detections of TCE. Dechlorination of TCE can occur by anaerobic biodegradation and abiotic degradation, as described by Wiedemeier et al. (998) and Vogel et al.,(987). Primary indicators of reductive dechlorination are the detection of degradation products of TCE which include DCE isomers, and VC. These compounds will degrade to final products including ethene, ethanol, and/or carbon dioxide. The presence of compounds such as,-dce, cis-,2-dce and VC indicate that degradation of TCE is occurring at the Site.,,-TCA was detected at OW9-I, OW2, OW8-I, OW23D, OW25, and OW26S in 20 at concentrations below the applicable standard.,-dca was detected above the applicable standard at OW26S at a concentration of 5. g/l. Concentrations of,,-tca and associated degradation product,-dca appear to be naturally attenuating at the Former IMICO site. Therefore,,-TCA no longer appears to be a contaminant of concern at the site. VOC concentrations were consistent with results observed in 200. Current and historical concetrations of TCE and,,-tca, and their primary abiotic degradation products are presented in Figure 5. Analytical results from 20 are included in Appendix B. Benzene, methlyene chloride and xylene have also historically been detected above the applicable standard, however concentrations have been at or near the laboratory detection limit across the Site since 2005.Therefore benzene, methylene chloride and xylene no longer appear to be contaminants of concern at the Site Polyaromatic Hydrocarbons (PAHs) PAHs at non detect concentration or were below the applicable standard at most monitored locations at and within the vicinity of the Site in 20. However, benzo(a)pyrene, benzo(k)fluoranthene, chrysene and fluoranthene were detected slightly above the applicable standard at OWS in 20 during both monitoring events. Benzo(a)pyrene was just above the applicable standard (0.0 g/l) at OW29S at 0.0 g/l, and OW28S at Benzo(k)fluoranthene was also slightly above the applicable standard at OW25 in September 20. Concentrations of PAHs at monitored locations continue to decrease at the Site, and are at or near the applicable standard. A summary of current and historical PAH concentrations are presented in Figure 6, and analytical results from 20 are included in Appendix B Petroleum Hydrocarbon Compounds (PHC) A summary of current and historical PHC concentrations are provided in Figure 7. Most monitoring wells sampled for PHCs were below the reportable detection limit. The laboratory results are included in Appendix B. Only three monitoring wells had concentrations of PHCs above the applicable standard in 20. These included OW25 with concentrations of F3 at 760 g/l and 4,00 g/l in June and September 20, respectively. OW24D had concentrations of F of 8 g/l (June) and,00 g/l (September), and OWD had concentrations of F of,00 g/l (June) and,200 g/l (September) in 20. Concentrations were consistent with historical results Polychlorinated Biphenyls (PCBs) PCBs have been sampled at OW29S and OW29D annually, due to historical detections of PCBs. In 20, PCBs were below the laboratory detection limit at both locations. PCBs appear to be no longer a contaminant of concern at the Site, therefore it is recommended that PCBs be removed from the monitoring program Former IMICO 20 Annual Groundwater Monitoring Report -FINAL.Docx 5

13 AECOM City of Guelph 20 Annual Groundwater Monitoring Report Former IMICO Site 4.3 QA/QC In order to assess field techniques and/or laboratory precision, blind duplicate samples were collected during each groundwater monitoring event. The relative percentage difference (RPD) between the samples collected for each monitoring well were calculated and were within +/- 25 and therefore AECOM considers there to be good reliability in the data. At each monitoring event a water sample was prepared by MAXXAM to determine if samples may be impacted during travel to the lab (trip blank). The trip blank was analyzed for VOCs and no detectable concentrations resulted. 5. Conclusions The following was concluded from results during the 20 groundwater monitoring at and within the vicinity of the Site; a) Consistent with historical data, shallow groundwater flow direction is in a southerly. There is a groundwater high in the deeper zone near OW23D, and groundwater flows away from this high across the site. Vertical hydraulic gradients in the shallow zone are generally downward. b) Zinc concentrations continue to be slightly above the applicable standard at monitoring wells located at the western portion of the Site. Lead was also detected just above the applicable standard at OW9-II in 20. c) Overall TCE concentrations are decreasing. The highest concentrations of TCE observed were in September of 4,600 g/l at OWD (located at 490 York Road) and at OW24D (located at the eastern portion of the Site) at 5,0 g/l. d) PAH concentrations were below the applicable standard at all wells at the Site. However, benzo(a)pyrene, benzo(k)fluoranthene, chrysene and fluoranthene were detected slightly above the applicable standard at OWS in 20 during both monitoring events. e) Four monitoring wells had PHC concentrations above the applicable standard located at the Site, and at the 490 York Road property. NAPL was measured at OW23S and it is not analyzed for PHCs, though it is expected that PHCs are present above the applicable standard at this location. f) PCB concentrations have been below the detection limit at monitored locations since PCBs are no longer a contaminant of concern at the Site. 6. Recommendations AECOM recommends that the City of Guelph continue groundwater monitoring at the Former IMICO Site in 202, however that the program be reduced to annually with the analytical program outlined in Table 2. AECOM recommends that groundwater elevations be collected in 202 semi-annually as compared to quarterly in 20. This is recommended based on consistent groundwater elevation and flow trends from year to year Former IMICO 20 Annual Groundwater Monitoring Report -FINAL.Docx 6

Used to evaluate the variance in the measurement. Matrix Spike: A sample to which a known amount of the analyte of interest has been added. Used to evaluate sample matrix interference. QC Standard: A blank matrix to which a known amount of the analyte has been added. Used to evaluate analyte recovery. Spiked Blank: A blank matrix to which a known amount of the analyte has been added. Used to evaluate analyte recovery. Method Blank: A blank matrix containing all reagents used in the analytical procedure. Used to identify laboratory contamination. Surrogate: A pure or isotopically labeled compound whose behavior mirrors the analytes of interest. Used to evaluate extraction efficiency. (Matrix Spike): The recovery in the matrix spike was not calculated. The relative difference between the concentration in the parent sample and the spiked amount was not sufficiently significant to permit a reliable recovery calculation. (RPD): The RPD was not calculated. The level of analyte detected in the parent sample and its duplicate was not sufficiently significant to permit a reliable calculation. Page 42 of 47
