Working under the supervision of the United States Environmental Protection Agency (USEPA) and the Indiana Department of Environmental Management (IDEM), they have conducted a thorough remedial investigation of the soils, sediment, surface and groundwater in LaSalle Park. In addition, the USEP A collected soil samples from residential yards in the neighborhood near the park. More than 1,000 samples were collected, including more than 270 from residential properties bordering the park. The samples were analyzed in more than 3,000 laboratory tests for more than 150 contaminants. Based on the findings of that investigation, more than 4,600 tons of soil from the park and two adjacent residential yards have been removed. More than 1,200 truckloads of clean soil were used to cap 3.2 park acres and the two residential yard areas. Background • From the 1930s to 1950s, portions of what is now LaSalle Park were used as an open dump by local residents and businesses. In the 1 960s, the City acquired the land to develop the park as a neighborhood amenity. • From 1988 to 2013 , the USEPA investigated the site in coordination with the City. These investigations resulted in multiple determinations that the site was low risk and did not pose a substantial threat to public health or welfare. • In December 2013 , the USEPA listed the site under the federal Superfund program. • In 2015, the City and Honeywell agreed to investigate LaSalle Park for the presence of contamination. The City and Honeywell identified many parties who potentially dumped at the site but the USEP A has not pursued them. Investigation / Protections • From 2016 to 2020, the City, Honeywell, and the USEP A conducted further investigations. In total, more than 1,000 samples were collected, including more than 270 from residential properties bordering the park. The samples were analyzed in more than 3,000 laboratory tests for more than 150 contaminants, including lead, arsenic, PCBs, pesticides, petroleum, and chlorinated solvents. • Elevated concentrations of lead were identified in three areas of the park and near two neighboring residences. While the soils next to the residences were believed to have been impacted by historic lead paint rather than proximity to the park, the City and Honeywell agreed to remediate the impacted soils at those two residences. • The investigation results indicated contaminants present in soils and groundwater had not migrated from the park into the surrounding area. Filed in Clerk's Office AUG 2 0 2026 Bianca Tirado City Clerk, South Bend, IN • Under the USEPA's oversight, a comprehensive health risk assessment was performed to evaluate potential exposure risks for residents and park visitors. No current exposure risks were identified, but there were potential future risks from certain soil excavation activities or from using parkland to grow produce for consumption. • In 2026, the City recorded an Environmental Restrictive Covenant (ERC) to foreclose potential future exposure risks. The ERC restricts agricultural uses in the park, restricts groundwater use, and requires future excavation work to follow an agency-approved soil management plan. • LaSalle Park and the surrounding neighborhood are on municipal water service; groundwater is not used at the park. Remediation • To expedite the remediation, USEP A approved the City and Honeywell moving forward with remedial work in 2022 based on approved technical assessments. • 1n 2022 to 2023 , the City and Honeywell performed an expedited removal action to excavate more than 4,600 tons of lead-impacted soil from the park and the yard areas of the two neighboring residences. • More than 1,200 truckloads of clean soil were then used to backfill and cap 3 .2 acres of the park. All clean soil was thoroughly sampled and vetted using USEPA-approved measures. • The City and Honeywell combined have spent approximately $7 .OM on the investigation and remediation work to date. • The City and Hyperion Environmental LLLP 11 are updating the technical submissions to reflect the completion of the work and existing site conditions. • After approval of the updated technical submissions, the USEP A is expected to issue a Record of Decision, after which the City and Hyperion will seek closure of the USEPA's Superfund process for the park. 1 On June 29, 2026, Honeywell lnternational lnc. spun off its aerospace business into an independent, publicly traded company named Honeywell Aerospace Inc. Hyperion Environmental LLLP r, a subsidiary of Honeywell Aerospace, has assumed responsibility to perform investigation and remediation work for the LaSalle Park Area agreement. 1 BECK'S LAKE SITE LASALLE PARK AREA SOUTH BEND, INDIANA E-----3 0.5 0 E-3 wood. 2 !Miles Prepared/Date: ARW 12/30/2015 Checked/Date: SOM 12/30/2015 SITE LOCATION MAP FIGURE 1 LEGEND 2016 & 2019 LEAD SAMPLE LOCATON 2016 (ONLY) LEAD SAMPLE LOCATION 2019AOC INVESTIGATION SAMPLES REMEDIATION AREAS: PLACEMENT OF ONE FOOT CLEAN SOIi COVER (6.6 ACRES TOTAL) 07 ~L,J.. __ _ 08 j /· ;09 76 •J 260 716 "' DECIDUOUS TREE CONIFEROUS IHcE ---------IRRIGATION LINES I I ATHLETIC FIELD 0155-1 46 5 [ Pavillion (JfS 120 EXTENT OF FILL ?06 01S5-3 39 02S5-3 54 300 [:] 30 a ....!4 04SS-1 40 03SS-1 1 _03S5j -04'~~-3 19Qi. 1 !1,10 I I 49.
