Landfill cleanup site — Restorical Research
528 S 108Th St Historical Fill
West Allis, 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 is an unlicensed historical waste site where foundry sand, construction debris, and other industrial fill material were deposited well before 1986, extending to depths of approximately 14 feet. Soil sampling dating to 1991 confirmed severe contamination already in place, including diesel range organics at 39,000 PPM, lead at 480 PPM, and elevated concentrations of PAHs, BTEX, petroleum hydrocarbons, cadmium, and PCBs. In 2014, two buried 55-gallon drums containing oil were uncovered from the fill during nearby highway interchange construction. The site is an active Wisconsin DNR Environmental Remediation Program case, with a site investigation workplan approved and contamination confirmed to have migrated to adjacent properties and a railroad right-of-way. 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.

The foundry sand, construction debris, and industrial fill at this property were deposited by operations conducted well before 1986, with soil sampling as early as 1991 confirming that severe contamination — including diesel range organics at 39,000 PPM, lead, PAHs, BTEX, cadmium, and PCBs — was already entrenched to depths of approximately fourteen feet, and with two buried 55-gallon drums of oil uncovered from the fill during nearby highway construction in 2014. The site investigation now underway under the Wisconsin DNR Environmental Remediation Program, together with the remediation of confirmed off-site migration to adjacent properties and a railroad right-of-way and the long-term monitoring and compliance obligations that will follow, represent future costs that the historical carriers insuring the businesses that operated here before 1986 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.
