6 1.1 Purpose GROUND PENETRATING RADAR SURVEY AND LIMITED PHASE II SUBSURFACE INVESTIGATION Parcels 1 and 2 along Forest Boulevard ( Block) East St. Louis Housing Authority East St. Louis, Illinois 1.0 INTRODUCTION ATC was retained by Sherman Carter Barnhart Architects to conduct a Ground Penetrating Radar Survey and Limited Phase II Subsurface Investigation of Parcels 1 and 2 along Forest Boulevard in East St. Louis, Illinois (the Site ). The Site is located north of Forest Boulevard with Parcel 1 having an address of Forest Boulevard and Parcel 2 being located in the 4300 block of Forest Boulevard, in East St. Louis, Illinois The objective of the investigation was to evaluate the subsurface soil and groundwater conditions at the Site for potential contaminant impact. This report presents a brief site history and the results of the subsurface investigation conducted on June 19 and 22, Site Description The Site consists of 10 parcels of land in the 4200 and 4300 blocks of Forest Boulevard, East St. Louis, St. Clair County, Illinois (refer to Figure 1 in Appendix A). The parcels located between North 42nd Street and North 43rd Street are referred to as Parcel 1 and the parcels east of North 43rd Street are referred to as Parcel 2. Parcel 1 contains six parcels of land, and Parcel 2 contains four parcels of land. Parcel 1 addresses are listed as 4201, 4209, and 4219 Forest Boulevard with Parcel Numbers , (023), (024), (025), (026), (027). Parcel 2 was not identified with any official address, but is located in the 4300 block of Forest Boulevard with Parcel Numbers , (020), (021), (022). The Site is currently vacant land and can be accessed from Forest Boulevard to the south. 1.3 Summary of Previous Assessments Based on the findings of the Phase I Environmental Site Assessment (PIESA) finalized by ATC on July 2, 2018, the following concerns were identified in connection with the property. ATC reviewed historical fire insurance maps for the property. After review of the maps, ATC discovered that an auto repair facility was formerly located on parcel number (eastern portion of Parcel 1 (4219 Forest)). In front of the auto repair facility (south side) there were two identified petroleum storage tanks. ATC attempted to obtain records regarding the former facility from the Illinois Environmental Protection Agency (IEPA) and the Office of Illinois State Fire Marshall (OSFM), but was unable to gather any pertinent documents on the property. At the time of the site visit, ATC did not observe evidence of the tanks at the surface of the location. However, due to the lack of records for this location, ATC was unable to determine if the tanks were underground storage tanks and/or are still in place on the property. The prior presence of petroleum storage tanks and a former auto repair facility on Parcel 1 is considered to be a recognized environmental condition to both this parcel and the adjoining western portion of Parcel 2 (across North 43 rd Street).

7 GROUND PENETRATING RADAR SURVEY AND LIMITED PHASE II SUBSURFACE INVESTIGATION Parcels 1 and 2 along Forest Boulevard ( Block) East St. Louis Housing Authority East St. Louis, Illinois Due to the potential for the tanks at the former auto repair facility to still exist and the lack of closure documentation at the property, a Vapor Encroachment Condition could not be ruled out. This limited Phase II subsurface investigation is intended to determine if subsurface environmental impacts are present beneath the Site. 2.0 SCOPE OF WORK The scope of work for this site investigation included the following principal tasks: Prepare a Health and Safety Plan (HASP) in accordance with the Occupational Safety and Health Administration (OSHA) 29 CFR ; Notify the State of Illinois utility locator service (JULIE) at least 72 hours prior to commencement of drilling activities; Conduct a limited ground penetrating radar (GPR) survey in the area of 4209 and 4219 Forest Boulevard; Complete eight (8) environmental soil borings at the Site; For each soil boring, conduct continuous soil sampling, evaluate each soil sample for staining, odors, or other physical evidence of impairment, and monitor the samples for the emission of total organic vapors using a photoionization detector (PID); Install 1-inch temporary wells in all eight (8) of the borings; Collect one soil sample from each of the eight (8) environmental borings and one (1) groundwater sample (if present) from each of the temporary wells for laboratory analysis; and Prepare a report to document the project activities and present the results of the Ground Penetrating Radar Survey and Limited Phase II Subsurface Investigation. 3.0 FIELD ACTIVITIES The Illinois state utility locator service (JULIE) was contacted 72 hours prior to commencement of field activities to have public utility lines marked in the vicinity of the Site. In addition, to minimize the risk of potential exposure to chemical and physical hazards associated with the subsurface investigation activities, a site-specific HASP was prepared. 3.1 Ground Penetrating Radar Survey A GPR survey was conducted at the Site on June 19, 2018, in an effort to determine if underground storage tanks are still present at the Site. The survey was completed in the area of 4209 and 4219 Forest Boulevard on Parcel 1. The area of the GPR survey is Project No. Z035CVR005 2 ATC Group Services LLC

8 GROUND PENETRATING RADAR SURVEY AND LIMITED PHASE II SUBSURFACE INVESTIGATION Parcels 1 and 2 along Forest Boulevard ( Block) East St. Louis Housing Authority East St. Louis, Illinois depicted in Figure 2 in Appendix A. The GPR survey was performed at the Site by Ground Penetrating Radar Systems, Inc. (GPRS). The GPR survey utilized a GSSI SIR processing unit with a 400 MHz antenna. The GPR instrument is a real-time locator that scans horizontally and vertically to a depth of approximately two to three feet at this Site. The ground penetrating radar survey was also used to clear utilities in the shallow subsurface at each boring location at the Site. Due to soil conditions present, the penetration depth of the GPR scan was limited to about two to three feet below ground surface. While this penetration depth was less than ideal, the resulting survey did not detect the presence of any anomalies consistent with the presence of an underground storage tank in the upper two or three feet of the subsurface. Appendix B contains a brief survey report from GPRS. 3.2 Phase II Subsurface Investigation The following field activities were conducted at the Site on June 22, 2018, to assess the potential presence of contaminant impact to soil and groundwater Boring Installation A total of eight (8) soil borings (B-1 through B-8) were installed at the Site utilizing a hand auger/direct push probe rig operated by Geo Drill, Inc. of Waterloo, Illinois. The borings were installed in the vicinity of the former auto repair facility and on the adjacent areas to the east and west. The Site is depicted on Figure 1 and the locations of the borings are illustrated on Figure 2 in Appendix A. The eight (8) borings were advanced to approximately 24 feet below land surface (bls). ATC geologists were on Site during the investigation activities to observe the drilling procedures, to visually classify soils in accordance with the Unified Soil Classification System (ASTM D-2488), and to evaluate the soil samples for staining and other indications of contamination. The soil borings were sampled on a continuous basis to the terminus depth of each boring using a hand auger or four-foot stainless steel sampler lined with disposable acetate liners. Soil samples were field-screened for the presence of total organic vapors with a PID. Geologic and hydrogeologic conditions and the PID measurements were recorded on the soil boring logs, which are provided in Appendix D. The subsurface material consisted primarily of clay Sample Collection Soil Sampling No significant visual or olfactory indications of contamination were observed during this subsurface investigation. Soil samples yielding the highest PID reading or located in the vicinity of the water table in each boring were submitted for laboratory analysis. Soil samples were collected in laboratory-supplied sample jars and preserved in accordance with Method 5035 protocols where appropriate. Samples for laboratory analysis were then placed in an ice filled cooler pending delivery to the testing laboratory. Chain-of-custody Project No. Z035CVR005 3 ATC Group Services LLC

9 GROUND PENETRATING RADAR SURVEY AND LIMITED PHASE II SUBSURFACE INVESTIGATION Parcels 1 and 2 along Forest Boulevard ( Block) East St. Louis Housing Authority East St. Louis, Illinois documentation was initiated in the field and accompanied the soil samples to Pace Analytical in Lenexa, Kansas. Groundwater Sampling A total of eight (8) temporary wells consisting of 1-inch diameter, Schedule 40 PVC slotted well screen and solid riser were installed in borings B-1 through B-8. Groundwater was encountered at a depth ranging from 7.1 to 11.8 feet bls in the borings. Hydrogeologic conditions are recorded on the soil boring logs in Appendix D. Groundwater samples were collected from each boring using dedicated, disposal bailers. Samples for laboratory analysis were then placed in an ice-filled cooler pending delivery to the testing laboratory. Chain-of-custody documentation was initiated in the field and accompanied the groundwater samples to Pace Analytical in Lenexa, Kansas Backfill and Decontamination Drilling and sampling equipment was decontaminated between borings and between each sample interval using a non-phosphate detergent solution and a clear water rinse. Where applicable, temporary well materials were removed and disposed following the completion of groundwater sampling. Soil borings were backfilled with hydrated bentonite and capped at the surface to match surrounding surfaces. 4.0 LABORATORY ANALYSIS AND RESULTS Soil and groundwater samples from all eight (8) borings were analyzed for volatile organic compounds (VOCs) by USEPA Method 8260, polynuclear aromatic hydrocarbons (PNAs) by USEPA Method 8270, and the eight RCRA metals (arsenic, barium, cadmium, chromium, lead, mercury, selenium, and silver) by USEPA Method 6010/7471. Groundwater samples were lab filtered for the analyses of the eight RCRA metals. Soil analytical results are summarized in Tables 1 and 2 (Appendix C) and groundwater analytical results are summarized in Tables 3 and 4 (Appendix C). Laboratory analytical reports including chain-of-custody documentation are provided in Appendix E. Soil and groundwater laboratory results were compared to the Illinois Environmental Protection Agency (IEPA) Tiered Approach to Corrective Action (TACO) Tier 1 Soil Remediation Objectives (SROs) and Groundwater Remediation Objectives (GROs) for potentially complete exposure pathways. The TACO Tier 1 SROs and GROs are included in Tables 1, 2, 3 and 4. Based on the soil lithologies encountered in the borings, ATC believes site groundwater classifies as Class II groundwater. Additionally, East St. Louis has adopted a groundwater ordinance that prohibits the use of groundwater in the city. Based on the fact that the investigation area is located in an area which contains a groundwater ordinance, the soil and groundwater component of the groundwater ingestion exposure route is considered an incomplete pathway at the Site. A copy of the East St. Louis Groundwater Ordinance is included in Appendix F. Based on the soil laboratory analytical results, acetone, sec-butylbenzene, cumene, n- propylbenzene, arsenic, barium, cadmium, chromium, lead, mercury, and a majority of the PNAs compounds were detected in at least one of the borings. However, all the detections were below TACO Tier 1 SROs. Soil analytical results are summarized in Tables 1 and 2 Project No. Z035CVR005 4 ATC Group Services LLC

10 GROUND PENETRATING RADAR SURVEY AND LIMITED PHASE II SUBSURFACE INVESTIGATION Parcels 1 and 2 along Forest Boulevard ( Block) East St. Louis Housing Authority East St. Louis, Illinois (Appendix C). Laboratory analytical reports including chain-of-custody documentation are provided in Appendix E. Based on the groundwater laboratory analytical results, 1,2-dichloroethane was detected in boring B-6 and barium was detected in all the borings. However, the barium detections were below TACO Tier 1 GROs and the 1,2-dichloroehtane was below TACO Tier 1 GROs with the exception of the Class I groundwater component of the groundwater ingestion route. Based on the fact that the Site is located in an area with a groundwater ordinance restricting the use of groundwater and that the groundwater is expected to be Class II in the vicinity, the Class I pathway does not apply to the Site. Groundwater analytical results are summarized in Tables 3 and 4 (Appendix C). Laboratory analytical reports including chain-of-custody documentation are provided in Appendix E. 5.0 CONCLUSIONS AND RECOMMENDATIONS The relatively low levels of compounds detected in the soil and groundwater samples collected during this investigation are below current Illinois action levels, and none of the detections exceeded TACO indoor inhalation levels. Based on the results of this investigation, and the fact that no current Illinois action levels were exceeded, ATC finds no further environmental investigations are currently warranted at the Site. ATC believes this assessment adequately addresses the Contamination and Toxic Substances evaluation for HUD per 24 CFR Part 58 (summarized on HUD Form 4128), as noted in Section of the Phase I Environmental Assessment Report Vacant Lots - Parcels 1 and 2, dated July 2, Qualifications The work performed in conjunction with this assessment, and the data developed, are intended as a description of available information at the dates and locations given.

We appreciate the opportunity to work with you. If you have questions regarding the results of this scanning, please contact the lead GPRS technician on this project. Equipment Used: The following equipment was used on this project: 400 MHz GPR antenna. Typically capable of detecting objects several feet deep. Maximum effective depth depends on site and soil conditions. At this site, the maximum effective depth of the GPR was 2'. RD 7000/8000 Radio Frequency detector. Detects electromagnetic fields. Used to actively trace metallic pipes and tracer wires, or passively detect electric,communications and other lines. Work Performed Ground Penetrating Radar Systems performed the following work on this project: Scanning the specified area to locate underground utilities and other significant anomalies. A tracer signal was sent along any accessible metallic utility or tracer wire, and the area was scanned with GPR to locate any additional targets. The locations of any detected utilities and anomalies were marked directly at the site with paint, flags, stakes, or other appropriate means, and results were reviewed with onsite personnel. Scanning the areas around proposed soil borings. Typically a 10' radius around each proposed soil boring will be scanned. A total of 2 boring locations were scanned. Scanning the designated area to attempt to locate evidence of underground storage tanks and/or UST removal excavations. The locations of any USTs, associated piping, or excavations detected were marked with paint, flags, or other appropriate means, and results were reviewed with onsite personnel. The total area scanned was approximately 10,000 square feet. The scanned area is the eastern half of the originally proposed area. No underground storage tanks were detected at this site. The areas were scanned thoroughly, and no anomalies consistent with the presence of an underground storage tank could be found. Grass was recently cut from 4'-6' tall to about 8". The grass clippings were laying on the surface. While scanning this may have effected the GPR data. Page 1 of 2
