Landfill cleanup site — Restorical Research
530 S 108Th St Historical Fill
Milwaukee, Milwaukee County
Restorical Research
Preliminary Site-Specific Analysis

This property has a documented history as a landfill predating 1986. Historical insurance policies issued during those prior operations and through 1986 could help fund the multi-phase investigation and remediation work ahead under Wisconsin DNR oversight.

This property served as an unlicensed waste disposal site where foundry sand, construction debris, and drums of industrial oil were deposited across the parcel, with fill extending up to 14 feet below ground surface. PCBs detected in the fill material confirm disposal occurred before 1979, and Wisconsin DNR has designated the site a Historical Waste Site under the Environmental Remediation Program. Site investigations beginning in 1991 and a 2024 Site Investigation Workplan have confirmed residual petroleum hydrocarbons, volatile organic compounds, polycyclic aromatic hydrocarbons, lead, cadmium, and PCBs in both soil and groundwater, with the water table sitting at only five to six feet below ground surface within the permeable fill. That history could support an insurance coverage claim against the carriers who issued policies more than 40 years ago — coverage that could help fund the cleanup ahead.

Why Historical Insurance Policies May Be Accessible

Pre-1986 Commercial General Liability (CGL) policies were occurrence-based and did not contain an effective pollution exclusion in Wisconsin — and those policies may provide coverage that remains enforceable today. If contamination occurred while those policies were active, those historical insurance carriers may still have a legal obligation to fund the cleanup costs, even if the business closed or the property changed hands.

Unlicensed waste disposal operations at this property — including the deposit of foundry sand, industrial oil, and PCB-containing materials that testing confirms predate 1979 — were conducted by businesses operating well before 1986. The site investigation, remediation of petroleum hydrocarbons, volatile organic compounds, polycyclic aromatic hydrocarbons, heavy metals, and PCBs in soil and groundwater, and long-term groundwater monitoring required by the Wisconsin DNR Environmental Remediation Program across 14 feet of contaminated fill represent substantial future costs that historical pre-1986 carriers may be obligated to fund.

Restorical's role is to locate viable historical policies, determine whether a successful coverage claim is possible, and assist our clients and their legal counsel to obtain insurance coverage. Restorical then manages the claim, including accounting, to ensure the cleanup is funded in a timely manner.

The Restorical Proven Process

Task 1 — Research and Analysis
Restorical searches for viable historical insurance policies, researches the site history, analyzes the contamination impacts, and underwrites potential coverage — including a proprietary trigger analysis. At the end of Task 1, we provide a clear yes or no on whether viable insurance coverage exists to fund the cleanup, along with a strategy and recommendation specific to your situation, even if you are not the policyholder.
Task 2 — Coverage and Funding
When Task 1 confirms viable coverage, Restorical works with your legal counsel to tender the claim, negotiate and secure insurance coverage. Restorical will manage the ongoing claim process, including accounting to ensure the insurance companies are funding your remediation in a timely manner.
