Dr. Martin Luther King Jr. Boulevard South Bend, Indiana 46601 Prepared by: Project No. 26-0526 April 20, 2026 Filed in Clerk's Offic OCT 1 2 2026 . Bianca Tirado City Clerk, South Ben Limited Subsurface Investigation 2018-2026 S. Main Street, South Bend, Indiana 1.0 INTRODUCTION 1.1 Purpose and Background On behalf of the City of South Bend Department of Community Investment (City), Heron Environmental, LLC (HERON) has prepared this Limited Subsurface Investigation (LSI) to document activities that have been completed at the parcels of vacant land located at 2018-2026 S. Main Street, in South Bend, Indiana (the Property). HERON understands that the Property is being considered for residential development. A Phase I Environmental Site Assessment of the Property was previously completed by Professional Service Industries, Inc. (PSI), dated March 23, 2026. PSI concluded that there were no Recognized Environmental Conditions (RECs), controlled-RECs, historical-RECs, significant data gaps, or potential vapor encroachment conditions (VECs) identified in connection with the Property. According to the PSI report the Property was originally developed with residential structures as early as 1917 with residential use continuing through the 1950s and by the 1950s the Property also supported commercial use including a furniture store, apartment complex, and several automobile garages. The Property reportedly transitioned to vacant land by 1975 and was redeveloped for commercial use between 1980 and 2010. Commercial operations initially consisted of silo construction and later conveyor millwright work and from 1987 to 2005 was occupied by Engineered Material Improvement (EMI) for abrasive blast cleaning and peening services. EMI abandoned the Property in 2005. The City, as prospective purchaser, submitted a Comfort Letter Request to the Indiana Department of Environmental Management (IDEM) Indiana Brownfields Program (IBP) in March 2010 based on the findings of a Phase I Environmental Site Assessment, dated March 15, 2010, prepared by Wightman Petrie, Inc. (WPI) for the EMI facility. WPI identified the following RECs in connection with the Property: • Equipment containing hydraulic oil and other hazardous substances is still inside the building, • Containerized fluid in the building that was not labeled or properly containerized, • Suspected asbestos containing material (ACM) were identified on the roof of the building as well as the vent pipe wraps, insulation, floor tiles and ceiling tiles, • Spent abrasive materials are present in particulate form throughout the interior of the building and caked on the asphalt paving south of the building in an area that apparently contained a dust collector. The following reasonable steps were recommended in the Comfort Letter, dated May 5, 2010: 1. The containerized chemicals inside the building should be characterized, removed and properly disposed. 2. The hydraulic equipment should be drained of product. Both the product and the equipment should be properly disposed. 3. All friable asbestos should be inspected/removed by a licensed Indiana asbestos abatement contractor prior to any building demolition, including proper notification of IDEM's Office of Air Management. 4. The spent abrasive material/ dust identified inside the building, as well as to the south of the building, should be characterized and properly disposed. 5. Samples should be collected from the water pits identified inside the building to determine the water's composition and proper disposal method. The City acquired the property in October 2011, and the building was subsequently demolished in 2012 Page 11 April 20, 2026 Limited Subsurface Investigation 2018-2026 S. Main Street, South Bend, Indiana with all the reasonable steps outlined in the Comfort Letter reportedly addressed. The City has indicated to the prospective developer that they will maintain responsibility for environmental issues that may be encountered during development. As such, the City requested HERON conduct environmental investigation to assess the potential for such environmental issues and the scope of work presented herein was completed in response to the request. 1.2 Property Location and Description The Property is in St. Joseph County, Portage Township, within the incorporated area of the City of South Bend, situated on the east side of S. Main Street, on the northeast corner of the intersection with Donald Street. The Property consists of three parcels ofland, Parcel Nos. 71-08-13-355-002.000-026, 71-08-13- 355-003.000-026, and 71-08-13-355-004.000-026, totaling approximately 1.07-acres. The Property is currently vacant land and is depicted on a 2023 aerial photograph provided as Figure 1 in Appendix A. 2.0 SCOPE OF WORK 2.1 Soil Sampling Methodology On April 7, 2026, nine soil borings were completed at the Property. Soil boring locations are presented on Figure 2 in Appendix A, which incorporates a 2005 aerial photograph to depict boring locations in relation to historical EMI commercial use. The borings were advanced in 5-foot intervals and soil samples were collected from every 2-foot interval and split into two portions. For each sample, one portion was placed directly into a laboratory provided sample container and placed on ice in a cooler, while the other portion was placed in a plastic baggie for field screening. Field screening was completed with a photoionization detector (PID) to detect the presence of volatile organic vapors in parts per million (ppm). Soil conditions and field screening results were recorded on soil boring logs completed for each boring, which are provided in Appendix 8. One soil sample from each soil boring was submitted for laboratory analysis of volatile organic compounds (VOCs) via US EPA Method 5035/8260, polynuclear aromatic hydrocarbons (PAHs) via US EPA Method 8270, and Resource Conservation and Recovery Act (RCRA) metals (arsenic, barium, cadmium, chromium, lead, mercury, selenium, and silver) via US EPA Method 6010. Soil samples for VOCs analysis were collected using 5-gram terra-core samplers and US EPA field preservation SW-846 Method 5035A. The sample containers were placed on ice in a cooler for delivery to Microbac Laboratories in Merrillville, Indiana. 2.4 Groundwater Sampling Methodology Three of the borings were advanced until saturated conditions (i.e., groundwater) was encountered and temporary wells were installed using a 5-foot section of 1.0-inch diameter, 0.010-inch slotted screen PVC placed at a depth to straddle the groundwater interface and completed to the surface with 1.0-inch diameter PVC riser. A peristaltic pump was used to pump the wells until discharge became relatively free of suspended particles and groundwater samples were collected into laboratory supplied containers and submitted for laboratory analysis of VO Cs (Method 8260). Sample containers were placed on ice in a cooler for delivery to Microbac Laboratories in Merrillville, Indiana. Following sample collection, the temporary well was removed, and the borehole was backfilled with bentonite chips. Page I 2 April 20, 2026 Limited Subsurface Investigation 2018-2026 S. Main Street, South Bend, Indiana 3.0 FINDINGS 3.1 Soil Boring Findings 3.1.1 Geology Soil borings were completed to total depths of 10-feet below ground surface (ft. bgs) to assess the surficial conditions at the Property. Three of the borings, 8-3, 8-6, and 8-9 were completed to total depths of 20-ft. bgs for temporary well installation. Soil encountered at the Property generally consisted of loose silty sand topsoil from surface to approximately 1-ft. bgs, underlain by fine to coarse grained sand with varying amounts of gravel to approximately 18-ft. bgs, underlain by dense clay. Some red brick fragments were observed in the 1 to 10-ft. bgs intervals of boring 8-4, coal/slag fragments were observed in the 1 to 3-ft. bgs interval of boring 8-8, and a pale granular material, possibly incinerator residue, was observed from 4 to 7-ft. bgs in boring 8-9. Saturated soil conditions (i.e., groundwater) were encountered at approximately 15 to 16-ft. bgs. The 1 to 2-ft. bgs interval of borings B-1, B-2, 8-3, 8-4, B- S, B-6, 8-7, and B-8 were submitted for laboratory analysis to assess the soil conditions that will be encountered during development. The 5 to 7-ft. bgs interval of boring B-9 was submitted for laboratory analysis to assess the pale granular material observed. 3.1.2 Field Screening There was no visual or olfactory evidence of potential contamination (i.e., petroleum staining or odors) observed in any of the soil borings and PIO readings were below 1.0 ppm except for in boring 8-9, which reported PIO readings of 1.0 to 1.3 ppm for the 5 to 15-ft. bgs intervals. 3.1.3 Soil Analytical Results The laboratory analytical results for soil samples are presented on Tables 1, 2, and 3 in Appendix C and the complete laboratory analytical report is provided in Appendix D. Each sample reported at least one VOC above the laboratory method detection limits (MDLs) with acetone, trans-1,2-dichloroethene, ethylbenzene, methyl bromide, methylene chloride, 2- methylnaphthalene, naphthalene, tetrachloroethene, tolune, 1,2,4-trimethylbenzene, and xylenes each reported in one or more of the soil samples; however the reported concentrations were all below 0.1 milligram per kilogram (mg/kg) and several orders of magnitude below their applicable IDEM Risk- based Closure Guide (R2) Published Levels (PLs). Several PAHs were reported at concentrations above the MD Ls in the samples from boring B-2, B-5, B-6, B-7, and 8-8; however, the reported concentrations were all below 1.0 mg/kg and several orders of magnitude below their applicable R2 PLs. The metals arsenic, barium, cadmium, chromium, lead, and mercury were reported in several of the soil samples at concentrations above the MDLs but well below applicable PLs. The highest reported concentration for arsenic was 2.88 mg/kg, below the PL of 10; barium was 96.8 mg/kg, below the PL of 20,000; cadmium was 0.136 mg/kg, below the PL of 10; lead was 143 mg/kg, below the PL of 200; and mercury was 0.118 mg/kg, below the PL of 3. Reported total chromium concentrations ranged from 4.15 to 11.9 mg/kg. Chromium speciation of the samples was not conducted and there is no PL for total chromium. The long- term residential PL for hexavalent chromium (Cr VI) is 4 mg/kg and the short-term excavation PL is 3,000 mg/kg. While noting that the reported concentrations of total chromium exceed the most stringent PL for Cr VI the reported concentrations are consistent across the Property indicating they are representative of naturally occurring total chromium concentrations and not associated with Cr VI, which is typically associated with electroplating, stainless steel production, and pigment manufacturing, Page I 3 April 20, 2026 Limited Subsurface Investigation 2018-2026 S. Main Street, South Bend, Indiana which are activities not known to have been conducted a the Property. 3.2 Groundwater Analytical Results The laboratory analytical results for groundwater samples are presented on Table 4 in Appendix C and the complete laboratory analytical report is provided in Appendix D. The only VOCs reported above the MDLs were acetone at concentrations of 0.93 to 2.3 micrograms per liter (ug/1), well below the PL of 20,000; tetrachloroethylene at 0.21 to 0.51 ug/1, well below the PL of 5; and toluene at 0.18 to 0.25 ug/1, well below the PL of 1,000. 4.0 CONCLUSIONS & RECOMMENDATIONS The results of this LSI did not identify evidence of potential contaminant concentrations above the applicable IDEM published levels. Based on the results of the soil samples analysis there does not appear to be any evidence of soil impact that would require consideration for residential exposure, or for proper handling or disposal during development. The results of the groundwater samples analysis do not indicate any potential groundwater contamination originating at or migrating through the Property. There is no evidence of a potential VEC to exist at the Property. Based on these results it is HERON's opinion that no further assessment of the Property is warranted. HERON has prepared this LSI in accordance with generally accepted industry standards of practice and consisting of a scope of work that would be considered reasonable and sufficient to identify the presence of a release at the Property.
